A growing number of autism researchers with the disorder are reshaping the field.

Roughly 1 in 125 people have autism spectrum disorder globally

The disorder has been increasingly diagnosed as its definition has grown broader and as clinicians have become more adept at identifying it—with some estimates suggesting the figures are much higher. These figures include people across the spectrum, some of whom live mostly independent lives, while others require life-long care and assistance.

Autism occurs among women, too

Males have higher rates of diagnosed autism than females, but recently scientists and people with autism have been exploring if females have been disproportionately missed in screening and if girls are perhaps masking their symptoms better, leading to missed diagnoses.

Autism rate increases are mostly among those with milder symptoms, not individuals with severe symptoms.

Autism spectrum disorder, defined in 2013, was previously categorized as numerous disorders.

Researchers are exploring neural links between Alzheimer's and autism

Recent DNA sequencing and molecular biology studies suggest that similarities in genes, neural circuitry and patterns of disease warrant further exploration to potentially better understand both conditions and how to treat them. (Some users may encounter a paywall.)

Autism research has faced significant cuts under Trump

One of the largest areas of halted research was at the Department of Education where its Institute of Education Sciences had studies underway focused on developing and evaluating school-based interventions for students with autism. DOE was significantly cut back as part of federal government layoffs.

Diagnosis as an adult can have huge benefits, including helping someone with ASD to feel real

This first-person account of a woman diagnosed with autism at age 31 covers her experience of why it was useful for her to receive her diagnosis as an adult and how it helped her to understand her life and her feelings of 'being an imposter.'

Watch this behind-the-scenes interview about the first person ever diagnosed with autism

Two reporters from The Atlantic tell the story behind their effort to track down the first diagnosed autism patient, Donald Gray Triplett, in Forest, Mississippi, and how his life turned out decades later.

1 in 31 kids in the US has autism

That figure comes from an analysis published by the US Centers for Disease Control and Prevention based on data gathered on eight-year-olds in 2022. Its figures mark a significant increase from 2000, when the estimated autism figure was one in 150, but improvements in diagnosis and changes to the disease criteria that broadened the diagnostic criteria are widely believed to be driving that increase.

The sibling of someone with autism has a 20% chance of developing ASD

The disorder is strongly linked with inheritance, and research suggests that if one child has ASD, there's a one in 5 chance the next child will develop autism, which is seven times more likely than the general population.

Some UK doctors pushed for broad 'do not resuscitate' orders for autistic adults during COVID

The controversial push was to create such orders without individuals' or their families' consent, underscoring modern-day prejudice against people on the spectrum.

Risk factors linked with ASD include older parents, preterm births, and toxic prenatal exposures

Though researchers agree that there is a strong genetic component to ASD development, certain environmental factors heighten that risk, with studies suggesting older parents, premature birth, maternal obesity, and air pollution exposure in utero all elevate risks of ASD development. There is no connection between receiving vaccines and ASD development.

Even if you have some ASD-linked gene variations you may not develop ASD

Individual environment and life experiences affect how genes perform in the body, potentially adding methyl groups to DNA that affect their function and turning genes on and off—which may heighten or reduce disease risk.

Gene expression patterns are similar between ASD, schizophrenia, and bipolar disorder

Postmortem brain tissue analysis suggests there are genetic and epigenetic similarities between individuals with autism, schizophrenia and bipolar disorder. All three conditions appeared to have activation of genes in astrocytes and suppression of specific genes that function at the junction between neurons, called synapses.

Autism and ADHD may have overlapping symptoms and someone can have both disorders

This video explores similarities and differences between these two disorders, which both have genetic causes. Challenges with attention, hyperactivity, and impulsivity are typical of ADHD. Fidgeting, problems picking up on social cues, emotional dysregulation, and being oblivious to time may occur with both disorders—though the impetus for these behaviors may differ.

'Love on the Spectrum,' a popular Netflix reality show, is following people on the autism spectrum as they navigate romantic relationships

This is one of Netflix's biggest shows, something this podcast says is due partly to the fact that the series both scratches the itch for people who enjoy reality dating viewing and the program is conducted in a nonexploitative, sensitive way that makes viewers truly want the best for the people navigating these situations.

A new schizophrenia healthcare model is giving patients more of a role in shaping their own treatments, with good results.

Support groups can offer insights into current and potential treatments

Beyond connecting with patients with similar experiences, support groups can also become centers for advocacy and for sharing research advances and medical experiences, including potential side effects from novel therapies or clinical trials.

Researchers are investigating how altering the gut microbiome may influence the development of rheumatoid arthritis, which is an autoimmune disease.

Autoimmune disease prevalence and incidence are on the rise—but no one knows why

Researchers theorize that environmental factors, including shifts to less healthy diets, air pollution, infections, stress, climate change, and exposures to xenobiotics—substances like pesticides, plastics, and toxins that incite immune responses—may all be fueling epigenetic changes to our bodies that make people's immune responses go awry.

Patients are a part of the progress

Navigating a cancer diagnosis can be terrifying and overwhelming. There is a robust community of patient advocates dedicated to prevention and diagnosis, research and clinical trials, legislation, needs of individual cancer types, among others. See how patient advocacy improves cancer research leading to improved treatment options and patient care.

Minorities are largely underrepresented in medical research, which compromises our understanding of how conditions and treatments may affect various populations, but recent efforts, like the African Ancestry Neuroscience Research Initiative and new genome research studies, are seeking to close that gap.

Scientists identify hundreds of genes responsible for OCD

Researchers analyzed the DNA of more than 53,000 people with OCD and identified 30 areas in the genome linked to the disease, containing 249 genes of interest. Of those, several were linked to other brain disorders, paving the way for genetic treatments of various mental illnesses.

People with schizophrenia are excluded from psychedelic research

Individuals with this mental health condition are routinely eliminated from any psychedelic research due to concerns about triggering or worsening psychosis. Yet there is little high-quality research in this area, raising questions about if further research into this question is warranted as interest grows in using psychedelics for therapeutic purposes.

Five advancements in arthritis research

It is estimated that nearly 350 million people worldwide are currently suffering from arthritis. This resource explores five of the most promising recent advancements in arthritis research as scientists work towards improved treatments and continue the search for a cure.

Advance genetic research by playing these scientific video games

Computers produce so much information that researchers can't properly analyze all the data produced, and the overload can also lead computers to make mistakes. Researchers are increasingly turning to citizen scientists—members of the public who are willing to volunteer—to help them make sense of data when computers can't. This article details a few of the ways you can contribute to genetics research by playing video games.

Recent evidence raises the question of whether conventional wisdom about amyloid plaques and their connection to Alzheimer's is wrong.

Does our fear of Alzheimer's create stigma around its treatment?

Surveys suggest our fear of Alzheimer's as a disease outranks that of heart disease and cancer. This piece argues our fear of aging and the slipping away of our mental capacities make it more difficult to treat Alzheimer's compassionately.

Psychedelic drugs are having a scientific renaissance

After decades of repression, psychedelic research is making a resurgence. Hear from a host of experts in this 20-minute video on what that could mean for the future of mental health. The current science on psychedelics believes LSD can cause a particular brain network to quiet or deactivate.

SAD uniquely affects people with attention-deficit hyperactivity disorder

Those with ADHD—chronic issues with attention and executive function—are primed for SAD. Many are disproportionately evening chronotypes (more awake in the evening), have a delayed sleep phase, and have low sensitivity to light in the morning. This podcast explores the overlap between these two groups.

Audism is institutionalized discrimination against deaf people

Promoting the idea of hearing-at-all-costs in medical and education settings has created division in the deaf community and influenced decisions about learning sign language.

Positive role models are a benefit of support groups

Meeting individuals who are going through similar life experiences or navigating similar health journeys can provide inspiration and be a benefit of attending in-person or online support groups.

Autoimmune disorders are one of the top 10 killers of young and middle-aged women

Studies in the US and the UK, though conducted decades ago, have underscored that autoimmune diseases, when grouped together, are a top killer of women.

35% of polled Americans said they'd view people differently if they knew they had a mental illness.

Researchers found that reading ‘Harry Potter’ made children more tolerant

Psychological research showed that children and young adults who read Harry Potter developed greater empathy and more accepting attitudes toward marginalized groups.

A top Alzheimer's researcher was accused of faking results

In 2021, an investigation revealed photo manipulation in images from a seminal 2006 paper by researcher Sylvain Lesné on the role of amyloid plaques in progressive Alzheimer's disease. The revelation rocked the field, leaving many wondering whether they had tried to build on fabricated results. (Some users may experience a paywall.)

Why are women more likely to suffer autoimmune diseases than men?

A majority of Americans with autoimmune diseases have more than one X chromosome, a typical marker of the female biological sex, according to a study published in February of 2024. During fetal development, cells side with one X chromosome over the other, preventing the overproduction of X-chromosome-specific proteins and shutting down the twin chromosome. This article explores how this X-chromosome inactivation can lead to autoimmune disorders by generating antibodies to the body's own tissues.

Adults are developing food allergies that they didn’t have as children

Research published in 2019 found that almost half of 40,000 surveyed adults with food allergies developed a new food allergy as adults, underscoring that our immune systems may newly misclassify substances later in life.

Researchers found that reading 'Harry Potter' made children more tolerant

Psychological research showed that children and young adults who read Harry Potter developed greater empathy and more accepting attitudes toward marginalized groups.

How can octopuses and MDMA help scientists understand the human brain?

Research shows that psychedelics may induce something called "critical periods" in the adult brain, which can make our brains more open to learning and changing, like they once were back in early childhood. Psychedelics similarly change how social creatures like octopuses behave, which demonstrates that these animals could help us better understand our own neurobiology.

Why CAR-T therapy has become one of the main focus areas for autoimmune diseases

The therapy, originally targeting cancer, involves taking a patient's own T cells, genetically reprogramming them to recognize and attack a specific target and then infusing them back into patients. For autoimmune diseases, the therapy instead programs them to target immune cells that are causing problems, restoring immune system tolerance.

Six of history's most unethical human experiments, from deliberate flu exposure to withholding syphilis treatment

Some of the progress made in mental health treatment, vaccines, blood transfusions, and more came about before the advent of consent and ethics committees, resulting in serious physical and psychological harm that participants in studies were not even anticipating.

The commercial and therapeutic potential of psychedelics

A 2006 study into the potential therapeutic benefits of psychedelics sparked a renewed interest in the field of psychedelic research, a development that has cascaded into commercialized ventures and experiences. This article details how growing research into the psychological benefits of psychedelics is matched by the rise of anecdotal reports, book deals, businesses, and corporate claims seeking to capitalize on psychedelic potential.

The Individuals with Disabilities Education Act improved the lives of many children with disabilities

Before the IDEA, many individuals lived in state institutions and received little education—only one in five attended public schools. Today, US public schools now educate over two-thirds of children with disabilities in general education classrooms.

Meeting someone with common healthcare challenges can be life-changing

The understanding that comes from meeting others who have similar experiences can provide hope that life can get better, the solace of affirmation, and make navigating a new diagnosis or a rare illness, in particular, much easier.

Multiple new research paths may lead to slowing (or even reversing) aging

Aging has always been inevitable, but fasting, epigenetic reprogramming, and parabiosis seem to help people stay young. By studying centenarians, memory, and even the humble roundworm, scientists are looking for the genetic basis to live not just a long life, but a healthy one.

The scandal that rocked stem cell research

In 2014, a Japanese research group published a paper suggesting ordinary cells could be reverted to pluripotent stem cells by subjecting them to external stressors. The results generated interest but could never be replicated. The lead researcher was accused of fraud, and the group’s supervisor committed suicide.

Gut microbiome rewrites may help reduce allergies

Researchers are investigating different strategies to determine if one day they could give people a combination of gut microbes to set them up for fewer allergies. In animal research, scientists have already prevented severe allergic responses in allergy-prone mice—supplying them with gut microbes from healthy, non-allergic human babies.
