It began with a fundamental mistake. For decades, families were blamed for a condition they did not cause. Mothers were labeled distant. Parents were treated as the problem. This was not simply incorrect. It caused real harm and delayed meaningful scientific progress. While the field defended a flawed theory, the biology of autism was largely ignored. Dr. Bernard Rimland challenged that directly. At a time when doing so carried professional risk, he argued, with evidence and persistence, that autism was biological. Not psychological. Not caused by parenting. That shift was not incremental. It was a course correction. And it changed everything that followed.","img_url":["https://autism.org/wp-content/uploads/2023/12/updated-Steve-crop-150x150.jpg","https://autism.org/wp-content/uploads/2018/11/researchers-400x233.png"],"video_url":[]},{"heading":"Following the Biology, Not the Narrative","paragraph":"The Autism Research Institute has remained committed to a principle that is often easier to state than to follow: follow the biology. Not ideology. Not trends. Not what happens to be most acceptable at a given moment. Over the past decade, ARI-funded research has focused on measurable biological processes: immune function, gastrointestinal health, metabolism, neurology, genetics, and environmental exposures. This is sometimes framed as narrow. It is not. It is necessary. Autism is not a single entity. It is a spectrum of biological differences that cannot be fully understood by observing behavior alone. Studying behavior without examining underlying physiology is like studying fever without asking what is driving it.","img_url":[],"video_url":[]},{"heading":"The Reality of Medical Burden","paragraph":"There is a reality that is often acknowledged quietly but not often confronted directly: Many autistic individuals live with significant, and sometimes severe, medical conditions. Not secondary issues. Central ones. Chronic gastrointestinal disease. Immune dysregulation. Severe sleep disruption. Allergies. Anxiety with clear physiological components. For many individuals, these are not peripheral concerns. They shape daily life. Ignoring these conditions in the name of reframing autism does not make them disappear. It leaves them unaddressed. ARI-funded research has focused on these challenges with increasing clarity. Studies examining gut inflammation, microbiome differences, immune signaling, and circadian disruption are not theoretical exercises. They are attempts to understand sources of discomfort, pain, and reduced quality of life. The goal is straightforward: Reduce suffering where it exists.","img_url":[],"video_url":[]},{"heading":"Systems, Not Silos","paragraph":"The science is moving in a direction that should have been obvious all along. Autism does not reside in a single system. Brain, immune system, gut, metabolism, and environmental inputs are interconnected. They influence each other continuously. Mitochondrial dysfunction, metabolic disruption, genetic susceptibility, and environmental exposure may combine in ways that produce very different outcomes across individuals. This complexity is sometimes used as a reason to simplify the argument. It should be a reason to take the biology more seriously, not less.","img_url":[],"video_url":[]},{"heading":"The Environmental Question That Remains Unsettled","paragraph":"Few areas in autism research generate more tension than environmental factors. The discussion is often polarized, either dismissed outright or pursued without sufficient rigor. Neither approach moves the field forward. ARI has taken a different position. The biology underlying individual variability, including how different systems respond to immune and environmental challenges, remains far from fully understood. Environmental influences are approached as biological variables, such as toxins and other exposures, with an emphasis on measurable effects. This includes asking questions that are often avoided. Science does not advance by declaring questions closed; it advances by asking them more precisely. Avoiding difficult questions may reduce controversy, but it does not increase understanding.","img_url":[],"video_url":[]},{"heading":"Neurodiversity and Biology: A False Divide","paragraph":"The neurodiversity movement has changed the conversation around autism in important ways. It has emphasized strengths, identity, and the need for acceptance. That contribution is crucial. But acceptance does not eliminate medical reality. Treating gastrointestinal disease, improving sleep, or addressing immune dysfunction does not alter identity. It addresses health. Framing biology and neurodiversity as opposing positions creates a false choice. It suggests that acknowledging medical challenges somehow undermines acceptance. It does not. If anything, ignoring medical issues in the name of acceptance risks overlooking suffering that is both real and, in many cases, treatable.","img_url":[],"video_url":[]},{"heading":"A Legacy of Challenging What Is Comfortable","paragraph":"Dr. Rimland did not work within the boundaries of what was comfortable or widely accepted. He challenged assumptions that were deeply embedded in the field. That remains necessary. Progress in autism research has not come from consensus. It has come from questioning it. ARI continues to support research that asks difficult questions and follows the data, even when the answers are not simple or widely agreed upon.","img_url":[],"video_url":[]},{"heading":"What Comes Next","paragraph":"The future of autism research will not be defined by a single explanation. It will be defined by integration: by bringing together genetics, physiology, environmental data, and lived experience into a more complete and nuanced understanding. It will also require greater precision, which will empower us to move beyond broad labels toward individual biological profiles. And it will require something that is often in short supply: a willingness to tolerate uncertainty while continuing to ask better questions.","img_url":[],"video_url":[]},{"heading":"The Bottom Line","paragraph":"The goal is not to resolve every debate. The goal is to improve lives. That means reducing pain where it exists. Addressing medical conditions where they are present. And being willing to examine biology without avoiding uncomfortable areas. It also means respecting individuals for who they are. These goals are not in conflict unless we choose to frame them that way. The Autism Research Institute continues to take a position that is both simple and demanding: Follow the biology. Ask the questions that others avoid. And do not turn away from what the answers reveal. Stephen M.

From the beginning, Bernard Rimland challenged the dominant view of autism as a purely psychological condition and argued that biology mattered (Rimland, 1964). That position was not widely accepted at the time, but history has proven it correct. Over the years, ARI expanded this biological focus to include genetics, nutrition, immune function, metabolism, and environmental exposures (Edelson, 2017, 2025a). The consistent message has been that autism does not arise from a single contributor, but from the interaction of multiple biological systems with the environment. One of the lessons learned over decades of research is that some of the most important influences are also the easiest to miss. They are small, commonplace, and part of everyday life. In a previous editorial, Invisible Threats: The Role of Environmental Toxins in Autism , I discussed how environmental exposures often remain underappreciated precisely because they are so familiar (Edelson, 2025b). Air pollution falls squarely into this category. ARI began paying attention to environmental factors long before large population studies were available. Early on, Rimland, Sidney Baker, Jon Pangborn, and others noticed patterns in parent reports and clinical observations that pointed toward immune dysregulation, metabolic burden, and environmental toxic load. These early efforts were not definitive, but they were consistent. Over time, many of the questions raised in those early years have become the subject of formal epidemiological and biological research (Goodrich et al., 2024; Masi et al., 2017; Oliveira et al., 2005). In this editorial, I focus on particulate matter, commonly referred to as PM. Particulate matter is a mixture of solid particles and liquid droplets, much of it produced by vehicle exhaust and other combustion sources. These particles range widely in size. Larger particles are heavy enough to fall out of the air within seconds or minutes and deposit on surfaces or in the upper airways. Smaller particles, including PM 2.5 and ultrafine particles (<2.5), can remain suspended for hours or days and travel long distances. Most people think of air pollution only when it is visible, as haze or smog on certain days. But particulate matter is present even when the air appears clear. It settles on cars and sidewalks, and more importantly, it is inhaled continuously . Exposure is not occasional. It is daily, and for many people, unavoidable. Because this exposure is constant and its effects are not immediately obvious, PM is often dismissed as background noise. Yet decades of research have established its role in heart and lung disease (see review Hamanaka & Mutlu, 2018). Only more recently has attention turned to its possible effects on other conditions (see review Brockmeyer & D’Angiulli, 2016). A growing number of studies from different countries now show associations between air pollution exposure and increased likelihood of increased brain-related disorders such as autism, Alzheimer’s disease, and dementia, particularly when exposure occurs before birth or early in life. From an ARI perspective, this trajectory is familiar. Initial observations raise concerns. Early studies provide signals. Over time, evidence accumulates across disciplines. That is exactly what has happened with particulate matter. How PM enters the body Two factors are especially important: particle size and toxicity. Particle size affects how easily particulate matter enters the body and reaches organs such as the lungs, cardiovascular system, and brain. Toxicity depends on chemical composition, and particles of the same size can produce very different immune and long-term biological effects. Ultrafine particles, produced largely by vehicle exhaust, particularly diesel emissions, are generally the most chemically reactive and inflammatory. Larger particles from sources such as wildfires and industrial emissions are typically less reactive but can still be harmful with chronic exposure. Several studies have examined how fine particulate matter may affect the central nervous system (Ishihara et a., 2025). Although air pollution has long been associated with respiratory and cardiovascular conditions, increasing attention is now being directed toward its potential neurological effects. Toxic components such as metals, microplastics, and organic compounds can, under certain conditions, move beyond the lungs and enter systemic circulation. Ultrafine particles may also reach the brain directly through the olfactory pathway or indirectly by influencing the integrity of the blood-brain barrier. Experimental and epidemiological findings suggest that chronic exposure is associated with neuroinflammation, oxidative stress, and altered neural function. Over time, these biological responses have been linked in population studies to a higher likelihood of neurological conditions, including autism, Alzheimer’s disease, and dementia. Clarifying the specific biological pathways involved remains essential for understanding how environmental exposures may influence brain development and long-term neurological health. Particulate matter is often treated as a single exposure, but it is not. The same PM level can reflect very different mixtures depending on the source, such as traffic, wildfire smoke, industrial combustion, or even suspended dust. These differences matter because chemical composition strongly influences biological impact. Combustion-related and ultrafine particles are generally more chemically reactive, more inflammatory, and more likely to carry toxic compounds on their surfaces. Over the past decade, gene expression profiling studies have helped clarify how PM affects biological systems. Despite differences in exposure conditions and PM sources, studies consistently report alterations in pathways involved in detoxification, inflammation, and oxidative stress. Findings from both animal and human exposure studies show similar patterns (Huang, 2013). Together, this evidence indicates that PM exposure can trigger coordinated changes in gene expression that influence immune and metabolic pathways. PM and autism Reports of altered detoxification pathways, chronic inflammation, and oxidative stress are not new to autism research. For decades, ARI has monitored patterns of immune activation and metabolic imbalance as a recurring theme. What is emerging more clearly now is the recognition that common environmental exposures may interact with these biological systems during critical windows of development, potentially amplifying underlying vulnerabilities (Ishihara et al., 2025; Jung et al., 2024; Wang et al., 2024). In recent years, numerous studies have linked exposure to air pollution with an increased likelihood of autism. These associations have been reported across multiple regions, including Asia (Chen et al., 2018; Li et al., 2026), Europe (Flanagan et al., 2023; Jin et al., 2024), and North America (Cloutier et al., 2025; Volk et al., 2013). Most of this research has focused on PM 2.5 and other common traffic-related pollutants. As expected in complex human studies, results vary across populations and methodologies, but the overall pattern of findings points in a consistent direction. As the research has matured, investigators have begun asking more refined questions. Does particle size matter? Are smaller particles more biologically active? Are there specific windows of vulnerability? Recent work, including analyses from the Childhood Autism Risk from Genetics and the Environment study, suggests that exposure to ultrafine particles during early childhood may be particularly relevant (Goodrich et al., 2024). This shift toward greater precision mirrors the broader evolution of autism research. Early work identifies associations. Later work clarifies timing, mechanisms, and susceptibility. ARI has encouraged this kind of careful progression from the beginning. How to prepare for PM exposure in early life Just as pregnant women are advised to avoid alcohol, cigarette smoke, pumping gasoline into their cars, and other toxic exposures, future public health recommendations may also include guidance related to air pollution. Such recommendations, potentially informed by statistical models, could take into account factors such as proximity to major roads or highways, distance from heavy traffic, and even temperature, since particulate matter can remain suspended in the air longer during warmer conditions (Leffel et al., 2025). For individuals who live in or spend substantial time in high PM environments, protective strategies may begin as early as preconception and continue through pregnancy and early childhood. These strategies could include using air purifiers in the home and workplace, wearing masks outdoors when pollution levels are elevated, and taking additional precautions to reduce exposure during a child’s early years. Other approaches may involve targeted nutritional supplementation aimed at supporting cellular resilience and detoxification pathways. As discussed in a previous editorial, the P2i program offers a comprehensive training framework for healthcare providers and families preparing for pregnancy or welcoming a new child, with the goal of reducing overall toxic burden. (See www.forump2i.com .) Continuing ARI’s legacy of careful, pattern-based inquiry As always, caution is essential. None of the conditions discussed above are caused by any single mechanism. Autism is certainly not caused by any single factor. Many autistic people are happy being autistic and see autism as part of neurodiversity, meaning all brains are different. Genetics, immune function, metabolism, and environment all play roles. The current research does not suggest that particulate matter causes autism. What it does show is biological plausibility of how pollution is impacting human experience. ARI has long emphasized that progress in autism research comes from recognizing patterns early and evaluating them carefully over time. The growing evidence linking particulate matter to neurodevelopmental vulnerability fits this pattern. These exposures are widespread, largely invisible, and part of daily life. As research advances, the most important questions may shift. Rather than asking whether particulate matter matters at all, the focus may need to move to when it matters most, how it interacts with underlying biology, and which individuals are most vulnerable. These differences likely reflect epigenetic and biological variability, since not everyone exposed to particulate matter experiences adverse effects. Addressing these questions aligns closely with ARI’s longstanding mission to integrate research, clinical insight, and real-world relevance.

CD for chlorine dioxide, or ASEA). Any medical treatment that uses “Miracle” on its label raises serious questions of old-fashioned fraud. In particular, suspicions arise with Miracle Mineral Solution, a product whose primary ingredient has side effects known to be seriously damaging. We recognize that there are off-label treatments with variable amounts of data that parents and practitioners will attempt. As pioneers in the use of a biomedical approach to autism, however, we maintain that it is critical that a treatment be considered reasonably safe before we give it to children. We do not consider MMS to meet these standards, and it violates the principal precept of medical bioethics: “first, do no harm.” While many families spend years trying to detoxify their children, MMS introduces a known toxin into their bodies. MMS has properties similar to Clorox® bleach, which can burn the upper digestive tract. The mucous threads that children expel during MMS treatment, which have been touted as worms (though laboratory analysis does not support this claim), are the body’s method of protecting itself from induced oxidative stress in the lower digestive tract equivalent to the mid-day sun in its ability to produce severe sunburn.","img_url":[],"video_url":[]},{"heading":"Long Term Effects","paragraph":"We simply cannot know what, if any, damage may occur in the long term. We have seen severe mineral deficiencies, malabsorption, loss of beneficial flora, and anemia in our patients who have undergone this treatment. The disruption of children’s gut epithelium and flora could have unforeseen consequences to their immune systems. At some point later in life, they may be also at higher risk for esophageal or stomach cancers, among other issues. Some parents of sick children report dramatic improvements in stool as well as other symptoms. Does this mean MMS is an effective treatment? Not necessarily. Nature’s strong impulse toward healing is stimulated by stress. Fasting, physical exertion to the point of exhaustion, sleep deprivation, torture, and severe physical and emotional trauma muster the resources of the mitochondria, muscles, mind, and soul to rise to the occasion. While any resulting temporary improvements may seem “miraculous,” there are safer and lower-risk ways to induce a healing response. Given these issues, we advise against using Miracle Mineral Solution at this time. We hope parents will remain critical of unsubstantiated claims that children have recovered or greatly improved in the absence of objective proof. We also strongly encourage any parents who choose to administer MMS to their children to report it to their physician so that side effects can be monitored.

For many years, professionals blamed “refrigerator parents” and prescribed psychoanalytic therapy. Once the psychogenic theory was debunked, genetic research began to dominate autism science. Today, while we know that genes play a significant role in autism, we are beginning to recognize the critical importance of another factor: the environment (Rimland, 1964). Currently, questions persist about the relative influence of genetics and environment on autism, with many people still viewing it as a purely genetic condition. However, as research findings mount, a clearer picture is forming. It is apparent that in many if not most cases, the condition arises from a complex interplay between genetic susceptibility and environmental influences (Hallmayer et al., 2011). Research increasingly shows that invisible yet potentially harmful substances can have long-lasting impacts on the fetus before birth and in the early stages of life, highlighting the need for us to take meaningful steps to reduce exposure to these substances—especially during crucial formative months in prenatal and early childhood development. I believe it is time for the autism field to move beyond the vague use of the word “environment” and begin focusing on specific environmental toxins implicated in autism. Identifying and drawing attention to these toxins will help us to guide public policy, develop targeted interventions, and protect future generations of children.","img_url":["https://autism.org/wp-content/uploads/2024/12/Edelson_12-24.jpg","https://autism.org/wp-content/uploads/2013/07/Untitled-design-48-400x225.jpg"],"video_url":[]},{"heading":"The interplay of genes and environment","paragraph":"When discussing the causes of autism, it is useful to frame the issue in terms of genetic susceptibility and environmental influences . Genetic susceptibility helps to explain why many individuals exposed to the same environmental toxin may experience little or no effect, while a small portion develop long-term disabilities. It is likely that there is no specific “autism gene,” but rather, a combination of genetic vulnerabilities that increase susceptibility to certain environmental influences. These vulnerabilities may affect systems such as the immune system, which protects the body from foreign substances, and the metabolic system, which affects the body’s ability to detoxify harmful substances.","img_url":[],"video_url":[]},{"heading":"Environmental risk factors currently implicated by research","paragraph":"Controlled studies on the effects of human exposure to toxins are of course neither ethical nor feasible, and correlational studies can only suggest an association rather than a cause-and-effect relationship. For example, autism appears to be more common in cities than in rural areas; however, this does not necessarily indicate a causal link, as better access to diagnostic services in cities likely accounts for this pattern. What adds credibility is that many of these risk factors show a distance or dispersion effect. The closer one is to a source—such as pesticides or particulate matter from vehicle exhaust—the higher the risk of autism (Shelton et al., 2014; Volk et al., 2011). In addition, replication by independent research groups in different regions of the country provides relatively strong evidence supporting a possible causal relationship (Becerra et al., 2013; von Ehrenstein et al., 2019). Environmental toxins that currently are strongly implicated in autism (see Goines & Ashwood, 2013; Landrigan et al., 2012) include: Air pollutants: particulate matter, nitrogen dioxide, ozone, carbon monoxide Pesticides: organophosphates, pyrethroids, permethrin, malathion, avermectin Metals: lead, lithium, mercury, cadmium, aluminum, chromium, arsenic, manganese Plastics and industrial chemicals: phthalates, bisphenol A, polychlorinated biphenyls (PCBs)","img_url":[],"video_url":[]},{"heading":"Patterns emerging from well-documented research","paragraph":"In addition to identifying environmental toxins that can alter fetal and early childhood development, it is important to understand the mechanisms by which they cause harm. We know that when toxins enter the body, their effects depend on several factors, particularly the ability of the immune and metabolic systems to defend against them. In addition, the level of exposure is critical. This includes both the duration and amount of exposure, as well as the timing. For example, there is evidence suggesting that certain adverse neurological events may occur during the second trimester of pregnancy (Bilder, 2019). Once toxic agents begin circulating in the body, they can trigger several well-documented biological processes linked to autism. These include brain inflammation (Vargus et al., 2005), oxidative stress (a marker of neuroinflammation; Usui et al., 2023), maternal immune activation (Ayoub, 2025; Usui et al., 2023), and disrupted cellular function. Naviaux (2020) has shown that cellular responses to toxins can initiate what is known as the cell danger response , in which the body enters a defensive state that can impair communication between cells. Interestingly, emerging research indicates that the effects of particulate matter extend to the gut microbiome (Filardo et al., 2022). Exposure to particulate matter has been associated with disruptions in gut microbial balance that are also reported in autism, including reductions in microbial diversity (Fouladi et al., 2020; Kang et al., 2017). Furthermore, decreases in Bacteroidetes and Lactobacillus —both reported in autism—have also been associated with exposure to particulate matter (Li et al., 2023; Strati et al., 2017; Liu et al., 2021; Mihailovich et al., 2024). Building on this understanding, a major study published earlier this year identified four distinct subtypes of autism (Litman et al., 2025; see ARRI 2025, Vol. 3). One subgroup, termed “broadly affected,” was characterized by severe delays in reaching developmental milestones such as walking and talking, along with pronounced social-communication challenges and marked restrictive and repetitive behaviors. This subtype closely corresponds to what is often referred to as profound or severe autism (Lord et al., 2024). Notably, autism that arises in the context of maternal immune activation during pregnancy—which can be triggered by toxic exposures or infections—is also frequently described as severe or profound (Ellul et al., 2023). What is very interesting is that both maternal immune activation profiles and de novo mutations were most prevalent in the “broadly affected” group. De novo mutations are not inherited from parents but instead arise spontaneously as errors during cellular replication, often occurring during early embryonic development. Their occurrence can be influenced by factors such as advanced parental age—a well-documented risk for both mothers and fathers (Croen et al., 2007)—as well as environmental exposures that disrupt genomic stability (Pugsley et al., 2022). This raises an important question: Could many individuals who are severely affected by autism represent cases in which toxic exposures during pregnancy trigger maternal immune activation and simultaneously contribute to the emergence of de novo mutations? Research exploring this possibility is urgently needed, as it may be relevant to more than one-quarter of the autism population (Hughes et al., 2023). In a related ongoing research project, Judith Miller, a clinical psychologist at the Children’s Hospital of Philadelphia, is conducting a comprehensive study of environmental factors to which individuals are exposed over time. She is leading a multi-year project that integrates genomic and exposomic data (the latter focusing on lifetime exposures to environmental factors) from more than 100,000 children, including about 4,000 autistic children, and links this data to detailed maternal health records. The study incorporates geospatial data on air and water quality, green space access, and a wide range of other environmental exposures to explore how genetic susceptibility and environmental context may interact in autism.","img_url":[],"video_url":[]},{"heading":"Final thoughts","paragraph":"Can we realistically reduce harmful exposures when they are so deeply tied to economic and political forces? Cleaning up pollution in the air, water, and soil is an enormous undertaking and often prohibitively expensive, but there are many practical and cost-effective steps we can take. In the near term, the highest priority should be protecting those most vulnerable: pregnant women and very young children. One promising effort in this area is P2i (Preconception to Infancy), a new initiative launched by the Northwest Autism Foundation. This comprehensive program is designed to support couples from the preconception stage through their children’s infancy, with the goal of promoting safer pregnancies and fostering healthier early development. One of the key goals of P2i is to reduce the body burden of toxic chemicals in mothers and their children. There is also growing interest in interventions to reduce the harmful effects of environmental toxic exposures in autism. Strategies focus on enhancing detoxification pathways, such as increasing glutathione synthesis and strengthening antioxidant defenses. Additional approaches that support mitochondrial function, lower oxidative stress, and modulate immune responses may further reduce toxicant burden and its neurodevelopmental impact (see Rossignol & Frye, 2012). Given the importance of efforts such as these, I believe it is time for the autism field to speak more openly and directly about specific environmental toxins and exposures. Greater transparency about these risk factors—such as exposure to certain heavy metals, pesticides, air pollutants, and prenatal stressors—will foster better public understanding and help guide prevention and policy efforts. Researchers and clinicians have a responsibility to communicate emerging evidence clearly and without unnecessary delay. Open dialogue among scientists, policymakers, and the public will accelerate progress toward reducing harmful exposures and improving outcomes for future generations. Stephen M.

ARI’s Commitment to Evidence-Based Research ARI is committed to monitoring ongoing research and sharing accurate, evidence-based information with autistic people, families, researchers, and policymakers. This includes addressing questions about environmental influences and potential medical factors, such as the use of over-the-counter medications. “We know there are subtypes of autism, with no single cause explaining the condition and no single intervention benefiting everyone on the spectrum. Research should focus on understanding these differences rather than generalizing findings to every autistic individual,” said ARI Chief Science Officer, Dr. Steve Edelson. “By identifying unique biological, developmental, and environmental factors within each subtype, we can begin to develop more targeted, effective approaches.” Acetaminophen Research The Autism Research Institute acknowledges that recent studies have examined potential associations between prenatal acetaminophen (commonly known as Tylenol in the U.S.) exposure and autism. While these studies contribute to our understanding of possible risk factors, ARI maintains that the current evidence does not establish a definitive causal relationship between acetaminophen use during pregnancy and autism. Extensive studies, including a 2024 Swedish study analyzing nearly 2.5 million births, suggest that observed associations between prenatal acetaminophen use and autism may reflect familial confounding rather than a direct causal link. Research led by Dr. Mady Hornig of Columbia University underscores the complexity of these factors. Her work highlights the role of maternal immune responses and fever, showing that inflammation during pregnancy may affect neurodevelopment independently of medication use. Preliminary evidence also indicates that acetaminophen taken to reduce fever may be neutral—or even potentially protective—though these findings remain inconclusive. Leucovorin (Folinic Acid) Research ARI has supported Dr. Richard Frye’s research related to leucovorin (folinic acid) as a potential intervention in autism, particularly for individuals with metabolic differences such as impaired methylation or glutathione production. We are encouraged by the preliminary results suggesting that leucovorin supplementation may benefit certain subgroups of individuals with autism spectrum disorders. Dr. Frye’s work represents potential progress in understanding possible biomarker-based approaches to intervention. However, we emphasize that this research is still evolving, and larger, controlled studies are needed to fully validate these findings and establish optimal treatment protocols. It is important to note that Dr. Frye’s leucovorin research explores potential therapeutic interventions rather than causative factors and should not be interpreted as supporting any specific theory about acetaminophen causation. Ongoing Commitment ARI remains committed to supporting rigorous, scientifically sound research into all aspects of autism spectrum disorders. We encourage: Continued investigation of the interplay between genetic susceptibility, environmental factors, and critical developmental periods Well-controlled studies that distinguish association from causation Investigation of maternal immune responses and inflammation as pathways to neurodevelopmental differences Research that includes autistic people and focuses on appropriate medical care Transparent communication about both the promise and limitations of emerging research Individuals, parents and healthcare providers are encouraged to make medical decisions based on established guidelines and consultation with qualified professionals, while staying informed about ongoing research developments. As Dr. Hornig notes, untreated fever during pregnancy carries known risks, and decisions regarding fever-reducing medications should be made carefully with medical guidance. “Autism is complex, and much remains to be learned,” Dr. Edelson said. “As always, ARI is committed to following the evidence wherever it leads and to providing clear, trustworthy information as new knowledge emerges.” Media Contact: [email protected]","img_url":[],"video_url":[]}],"_id":"6a34f294631514ff2252efb9"},{"title":"Editorial: Navigating New Territory – The Growing Focus on Autistic Seniors","short_description":"This editorial originally appeared in ARI’s Autism Research Review International –","image":"https://autism.org/wp-content/uploads/2025/09/IMG_7709-scaled-e1757607275433-400x426.jpg","details_url":"https://autism.org/growing-focus-on-autistic-seniors/","long_description":[{"heading":"","paragraph":"This editorial originally appeared in ARI’s Autism Research Review International – now available online.

As the prevalence of pediatric autism diagnoses has increased over the past three decades, researchers and service providers have broadened their focus to include the needs of individuals transitioning to adulthood and young adults. Today, there is increasing recognition of the importance of supporting autistic individuals throughout the entire lifespan, including old age. In a 2017 report to Congress, the U.S. Department of Health and Human Services estimated that approximately 50,000 autistic youth are expected to transition into adulthood each year in the United States. Over the coming decades, a growing wave of these individuals will be entering later adulthood. Medicaid enrollment data has shown a steady increase in service use for this group. The issue of aging in autism began to gain attention about a decade ago, and continues to grow in importance as rising numbers of autistic individuals age into their senior years. Prominent autistic individuals who are now over 60 years of age—including Temple Grandin, Stephen Shore, John Elder Robison, Wenn Lawson, Cos Michael, and Mark Rimland, the son of Dr. Bernard Rimland—highlight the relevance of this issue. Some of the needs of autistic seniors, such as the requirement for appropriate living arrangements and good health care, appear straightforward. However, many less-obvious challenges are becoming clear as we are now hearing from autistic individuals approaching their senior years as well as from clinical and community researchers who are studying aging. To explore these challenges, a dedicated group of autistic individuals and researchers has been meeting nearly monthly for approximately five years to discuss aging-related issues. This group has organized two major think tanks, resulting in published articles discussing their findings and conclusions (Edelson et al., 2023; Nicholas et al., 2025). This group is currently planning a third think tank meeting at the United Nations, scheduled for next month (October 3, 2025). In preparation for this upcoming event, several additional autistic individuals have joined the planning committee to help determine important topics for discussion. Recently, during one of their planning meetings, I was struck by the sheer number and complexity of senior-related issues identified by participants. To help prioritize these topics for the upcoming U.N. think tank, I asked the participants to rank these topics based on their perceived importance. As the result of this ranking, the identified topics have been grouped under five key areas: In the area of Physical and Mental Health in Aging , participants noted concerns related to dementia, Parkinson’s disease, extrapyramidal symptoms, and other age-related medical conditions (e.g., cancer, cardiac disease, stroke). They also stressed the importance of understanding the impact of medications on aging autistic individuals and exploring implications of hypermobility in older autistic adults (for example, those with Ehlers-Danlos syndrome). The broader spectrum of physical and mental health challenges associated with aging was recognized as posing concerns requiring urgent attention. Regarding Healthcare Access, Navigation, and Delivery , participants highlighted menopause as an area in which there are significant unmet healthcare needs. They also emphasized the importance of making healthcare systems easier to navigate and reducing administrative burdens and bureaucratic barriers. Additionally, there was considerable concern about addressing the needs of autistic seniors requiring long-term care or acute medical treatment, including issues involving hospital admissions. Preparing autistic adults to communicate effectively with healthcare providers during medical visits was also identified as a critical area, along with addressing sensory sensitivities and nutritional needs in outpatient surgery units, long-term care facilities, and other healthcare environments. Participants noted that differences in sensory processing, communication, and stress response among autistic individuals may complicate the recognition and treatment of age-related health conditions, often leading to misdiagnosis or delayed care. They also stressed that autistic individuals should receive routine preventive care, including colonoscopies, prostate screening, and mammograms. Tailored clinical approaches that account for neurodivergent aging trajectories are urgently needed. In the domain of Community, Autonomy, and Daily Life , the benefits of receiving a late autism diagnosis and self-recognition in older adults were highlighted. Community living options, regular health screenings, and protection from financial vulnerability were viewed as crucial for maintaining autonomy and quality of life. Participants noted the importance of supporting autistic individuals’ rights and legal capacity, while examining mechanisms such as guardianship and newer avenues such as supported decision-making and co-decision-making. Additionally, loneliness, social isolation, and parenting challenges faced by aging autistic adults—particularly those diagnosed later in life—were identified as vital areas of concern. Social Determinants of Health and Discrimination also emerged as critical issues, with contributors expressing deep concern about ableism, ageism, housing insecurity, retirement, and forced retirement. Intersectionality, especially involving LGBTQIA+ and other multi-marginalized identities, was underscored as needing more focused attention. Participants also suggested learning from other sectors, such as the LGBTQIA+ community, in order to better address systemic issues. Finally, End-of-Life and Palliative Care was recognized as an essential area needing more comprehensive planning and support. Participants emphasized the importance of respectful and informed end-of-life decision-making and palliative care tailored specifically for autistic individuals, including making clear and accessible communication readily available. The richness and complexity of the issues discussed illuminate an undeniable reality: Proactive engagement and systemic preparation are vital. Addressing these topics not only will aid autistic adults in navigating their later years but also will help to build an essential framework for policymakers, caregivers, support persons, healthcare providers, and society at large. Enhanced research, informed policy development, and dedicated resources will ensure that autistic seniors can live with dignity, autonomy, and comprehensive support. Critical to this aim is the key role and contribution of autistic people themselves in determining their priorities and what is needed in their middle and later years. It is crucial that ongoing dialogues and forthcoming initiatives foster increased awareness among autistic individuals, families, support networks, healthcare practitioners, and policymakers. Collectively, these collaborative efforts can drive meaningful changes in both practice and policy, ultimately creating a world where autistic seniors can thrive throughout their aging process. Although awareness of the needs of the aging autistic community is increasing, the time for action is now. We must seize this momentum to ensure that autistic seniors experience the highest possible quality of life, made possible by informed, compassionate care, oversight, and support and a well-designed infrastructure capable of meeting their evolving needs.

Adolescence, she explains, is a transformative stage characterized by significant psychological, social, emotional, and hormonal shifts, typically spanning ages 10 to 24. Within this broader period of adolescence, puberty specifically marks the biological maturation that leads to reproductive capacity and further psychosocial development (5:10) . For autistic individuals, who often experience challenges with social communication, adaptability to change, and sensory sensitivities, navigating these developmental milestones can be particularly complex. The presenter explains that early onset puberty can increase the risk for mental health problems, such as anxiety, depression, and suicidality, which are already more prevalent in adolescents with autism (05:58) . Until recently, research on puberty and autism has been limited. Some recent studies suggest that while social cognition might improve during puberty, social withdrawal can intensify, and about a third of youth experience significant psychosocial problems. Further, female-presenting autistic people have reported challenges with emotion regulation and heightened sensory experiences during menstruation (08:06) .

She outlines a recent publication by her team which found that pubertal assessments by parent or child are not reliable indices of precise pubertal staging, compared to physical exams (11:05) . Corbett and her team use all three methods of measurement in their studies to compare perceived development with physical indices. The speaker touches on models and frameworks used to help understand the links between mental health, puberty, and autism. A study published by Corbett and colleagues in 2020 shows that autistic females experience significantly earlier breast development and onset of menses compared to typically developing females, while pubertal onset for autistic males is similar to neurotypical males (13:15) . A longitudinal study assessing the progression of puberty in the same participants between 10 and 15 years of age verified these findings. Corbett reiterates that pubertal onset “sets into motion a cascade of events which may magnify and further complicate an already vulnerable trajectory, especially in females (17:00) .” Pubertal Development Measurement in Children With and Without Autism Spectrum Disorder: A Comparison Between Physical Exam, Parent- and Self-Report (Corbett et al., 2019) Pubertal Timing During Early Adolescence: Advanced Pubertal Onset in Females with Autism Spectrum Disorder (Corbett et al., 2020) Examination of pubertal timing and tempo in females and males with autism spectrum disorder compared to typically developing youth (Corbett et al., 2022)","img_url":[],"video_url":[]},{"heading":"Altered cortisol levels in autism","paragraph":"The speaker describes the Hypothalamic-Pituitary-Adrenal (HPA) axis, which plays a vital role in our stress response by triggering a neuroendocrine cascade to produce cortisol. Cortisol, she continues, is a widely used biological marker found in blood and saliva (19:00) . Normally, cortisol levels peak in the morning and decline throughout the day. However, Corbett’s research consistently shows that autistic children exhibit significant variability in cortisol levels, with persistently elevated evening cortisol and a “blunted slope” compared to their allistic peers. This means their cortisol doesn’t rise or drop to the same level, impacting their ability to feel energized during the day and rest well during the night (20:30) . Another longitudinal study on cortisol trajectory further revealed that HPA axis maturation is impacted by age, puberty, sex, and an autism diagnosis, where females had higher overall cortisol and higher evening cortisol than the males in both groups (22:00) .

A study conducted by Corbett and Dr. Jessica Schwarzman found that depressive symptoms are significantly higher in both autistic males and females as early as 10-13 years of age. Parents corroborated these findings, reporting higher depressive symptoms in their autistic children, especially in females (25:25) . The presenter therefore asserts that screening and intervention for depressive symptoms for autistic individuals should begin very early in adolescence. She notes that symptoms were often related to interpersonal problems and feelings of worthlessness, which are crucial intervention targets (28:00) . Corbett outlines a recent longitudinal study on the trajectory of depressive symptoms which revealed that while autistic individuals reported significantly higher depression symptoms at age 10, their symptoms actually decrease through adolescence, contrasting with an increase seen in allistic youth around ages 14-15 (30:00) . The speaker notes that if replicated, this data warrants significant attention, potentially pointing to earlier identification and treatment for autistic youth. Higher depressive symptoms in early adolescents with Autism Spectrum Disorder by self- and parent-report compared to typically-developing peers (Schwartzman & Corbett, 2020) Diagnostic- and sex-based differences in depression symptoms in autistic and neurotypical early adolescents (Schwartzman et al., 2022) Trajectory of depressive symptoms over adolescence in autistic and neurotypical youth (Corbett et al., 2024)","img_url":[],"video_url":[]},{"heading":"Hormonal differences","paragraph":"Corbett explains that imbalances in hormones such as testosterone may modulate autism phenotypes. However, there is limited research regarding variations in testosterone during adolescence in autism (34:15) . She details a recent study comparing salivary testosterone between autistic and allistic groups and male vs. female participants, with considerations of developmental stage. Data show that in autistic youth, both males and females exhibited significantly elevated testosterone compared to allistic youth. While male testosterone levels rapidly increased as expected during adolescence, females initially had higher testosterone until around 11.5 years of age before plateauing. Corbett states that these findings may suggest testosterone does play a role in autism, especially during periods of hormonal change (36:00) . Salivary testosterone in male and female youth with and without autism spectrum disorder: considerations of development, sex, and diagnosis (Muscatello et al., 2022)","img_url":[],"video_url":[]},{"heading":"Gender diversity in autistic young people","paragraph":"Adolescence is a time of profound self-exploration, including gender identity, or a person’s innate sense of gender. The speaker highlights recent research suggesting a higher prevalence of gender diversity in individuals diagnosed with autism or having autistic traits compared to their allistic peers. Corbett’s team used both self-report and parent report questionnaires to confirm this finding in autistic children (37:00) . Parents of autistic children reported significantly greater “gender body incongruence” in their children compared to parents of allistic children. Furthermore, within the autistic group, those assigned female at birth reported significantly more experiences of gender body incongruence than those assigned male. Self-reports from autistic youth also indicated significantly more reports of both “gender diversity” and “non-binary diversity” (40:00) . A follow-up study assessing gender diversity throughout adolescence found that gender incongruence was relatively stable across puberty in males (autistic and allistic). In contrast, autistic females endorsed greater incongruence around age 10, followed by a short plateau and then another increase. Allistic females reported the opposite pattern. Corbett summarizes these findings, highlighting the sex-based differences that indicate greater gender diversity in autistic females assigned at birth (AFAB). She also reiterates that gender identity formation is nuanced and likely influenced by pubertal progression, hormone patterns, and psychosocial factors (42:00) .

Autistic young people also have a higher rate and earlier onset of depression and a greater prevalence of gender diversity, especially in females. The speaker underscores the need for comprehensive measurements of psychological variables based on self-report, parent-report, and clinical-report. She emphasizes the need to identify risks and opportunities for resilience to elucidate and support the dynamic transition of puberty (43:00) . Corbett and her team recently received funding to renew their longitudinal study of pubertal development. The renewed study aims to examine pubertal development through age 17 by observing physical development, hormones, menstruation, social communication, and internalizing symptoms. It also aims to observe the nervous system during these periods in a group of more than 300 participants (45:00) . She notes an ongoing female development study before the Q&A (47:30) .
