Genetic study reveals autism diagnosis timing linked to distinct genetic and behavioral patterns, not milder symptoms.
A new study finds genetic factors explain about 11% of why autism is diagnosed at different ages, with early diagnoses linked to pronounced early social and behavioral challenges, while later diagnoses correlate with higher rates of ADHD and depression.
Researchers identified distinct genetic and developmental patterns between groups, challenging assumptions that later diagnoses reflect milder symptoms or access barriers.
The findings suggest autism may involve genetically distinct subtypes with varying trajectories, highlighting the need for personalized diagnosis and support.
