Yes, even in cases of sudden autism and inherited traits, genetic factors may still play a meaningful role. While autism regression where a child loses previously acquired skills can appear abruptly, underlying inherited traits might create a genetic susceptibility that contributes to the condition’s emergence or intensifies its course.
Regression is often noticed between 15 and 30 months, typically involving a loss of language or social skills. Although this seems sudden, the child may already carry subtle indicators linked to family history. Diagnosis timing can be influenced by how noticeable the regression is, yet genetics still factor into how a child processes development and stress. Even without early signs, inherited traits may underlie how regression unfolds.
Signs to Watch For
While some children show signs of autism from early on, others may regress:
Loss of speech or eye contact:
A child may stop using words they previously knew or avoid interaction. CBT can help rebuild communication and develop coping strategies.
Increased sensitivity or withdrawal:
Sudden aversion to sounds, textures, or social settings may appear. Occupational therapy and behavioural support are useful here.
Understanding the interplay between regression and inherited risk helps create targeted, timely interventions.
