What the Research Actually Says

Autism Prevalence: 1 in 31

The CDC's Autism and Developmental Disabilities Monitoring (ADDM) Network report published in 2025 found that about 1 in 31 children aged 8 (32.2 per 1,000) across 16 US sites had been identified as autistic in 2022. That is up from 1 in 36 in the 2020 data and 1 in 44 in the 2018 data. The report describes increased identification, particularly among very young children and previously underidentified groups. Identified prevalence was 3.4 times higher in boys (49.2 per 1,000) than girls (14.3 per 1,000). The boy-to-girl ratio has narrowed from 4.2 in 2018 to 3.4 in 2022, but the CDC cautions that this should not be read as better identification of girls, because the absolute gap between boys and girls actually widened.

The Double Empathy Problem

Damian Milton's paper proposed that the communication difficulties between autistic and non-autistic people are mutual, not a one-sided deficit in autistic people. A 2020 study by Crompton and colleagues tested this with a story-passing task: autistic people shared information with other autistic people as well as non-autistic people did with each other, but much less information was shared in mixed groups,, and mixed pairs reported lower rapport. The implication: the burden of accommodation should not fall entirely on autistic people.

ABA and PTSD Symptoms

This study surveyed 460 autistic adults and caregivers of autistic children online. It reported posttraumatic stress symptoms in nearly half of participants who had been exposed to ABA, and found that ABA exposure predicted a higher rate and more severe symptoms. Participants were recruited through social media and support groups and adults could be self-diagnosed, so the sample may not be representative, and the study cannot prove causation. In December 2025 the journal published an expression of concern about the study. It is consistent with first-person autistic accounts describing distress from compliance-based therapies, but its findings should be read with that caution in mind.

Camouflaging and Mental Health

This study of 262 autistic people looked at why, where, and at what cost they camouflage (mask). Camouflaging heavily across many settings, and switching between camouflaging in some settings but not others, were both linked to poorer mental health. Autistic women were more likely than men to camouflage for "conventional" reasons, such as getting by at work. The findings support what autistic advocates have long said: pressure to hide being autistic has real costs.

Autistic Burnout

This community-based study, built on 19 interviews and 19 public internet sources, described autistic burnout as chronic exhaustion, loss of skills, and reduced tolerance to stimulus. Participants described it as caused by life stressors that added to their cumulative load, plus barriers to support that left no relief. The authors concluded it appears distinct from occupational burnout or clinical depression. Participants associated recovery with acceptance and social support, time off or reduced expectations, and doing things in an autistic way, including unmasking.

Late Diagnosis and Identity

In this study, 77 adults described what it was like to realize they were autistic in adulthood. Six themes came up: feeling different from others, riding an emotional rollercoaster, striving to accept themselves, finding strategies to improve their lives, maintaining normalcy, and wandering into the future. The author calls for support after a new adult diagnosis, including screening for depression, and for removing barriers to getting a formal diagnosis.

Gender Diversity in Autism

Using five datasets covering 641,860 people, this study found that transgender and gender-diverse people had, on average, higher rates of autism diagnosis than cisgender people, and scored higher on self-report measures of autistic traits. Earlier, a 2014 chart review by Strang and colleagues found parent-reported gender variance in 5.4% of autistic children, compared with 0 to 0.7% in non-referred comparison groups. Why the overlap exists is not yet understood.

Autistic Girls and Diagnostic Bias

This meta-analysis of 54 prevalence studies found an overall male-to-female ratio of about 4.2 to 1, but studies that screened whole populations, rather than counting children already diagnosed, found a lower ratio of about 3.25 to 1. The authors concluded the true ratio is closer to 3:1 than 4:1, and that girls who meet the criteria for autism are at disproportionate risk of not receiving a clinical diagnosis. An earlier review by Kirkovski and colleagues (2013) also noted a strong bias toward male presentations in the autism literature.

Quality of Life and Acceptance

In this online survey of 111 autistic adults, acceptance of autism by others and personal acceptance both significantly predicted depression, with more acceptance linked to fewer depressive symptoms. Acceptance from others also predicted stress, but acceptance did not predict anxiety. The authors also found camouflaging may relate to higher depression. Acceptance is not only a value, it is linked to mental health.

Sensory Processing and Anxiety

This review notes that anxiety and sensory over-responsivity are both common in autistic children and that there is evidence the two are associated. It sets out three possible explanations: sensory over-responsivity is caused by anxiety, anxiety is caused by sensory over-responsivity, or both share a common cause, and it discusses what each would mean for support. The causal direction is not settled, but the link is a good reason to look at the sensory environment when a child is anxious.
