Autism Diagnoses Are Delayed for Females Compared to Males Due to Delayed Recognition of Symptoms and Diagnostic Gaps

A significant study tracking 2.7 million individuals in Sweden between 1985 and 2022 has revealed a notable catch-up effect in autism diagnoses among adolescent girls. While autism is often diagnosed at younger ages in boys, the research indicates that by the age of 20, the male-to-female diagnosis ratio evens out to nearly 1:1. This suggests that diagnostic delays are common for females, with diagnosis rates peaking later for girls (ages 15-19) than for boys (ages 10-14). This underdiagnosis is a serious concern, as undiagnosed autism is frequently linked to severe difficulties and suicidality.
Delayed Visibility of Autistic Features in Females

Research indicates that certain autistic features may be present in males earlier but only become visible in females during adolescence. Studies focusing on children might therefore miss these characteristics as they are not yet apparent in girls. This difference in the timing of symptom presentation contributes to the diagnostic lag experienced by females.
Social and Communication Skills Masking Symptoms

The higher prevalence of better social and communication skills among girls is often cited as a reason why autism is more difficult to detect in females. These developed skills can potentially mask or compensate for underlying autistic traits, making it harder for clinicians and parents to identify the condition during routine assessments. This can lead to a later recognition of the disorder.
Gaps in Current Diagnostic Practices

Patient advocates and researchers highlight that current diagnostic practices may be failing to adequately recognise autism in women and girls. Dr. Rachel Moseley notes a substantial gap in diagnosing autism in females, and patient advocate Anne Cary suggests that many women are not diagnosed until much later in life, if at all. This points to a potential need for revised diagnostic criteria or approaches that are more attuned to the presentation of autism in females.
