Brief report: effect of maternal age on severity of autism.

Doctors tested 154 kids with autism who came to a clinic. They asked: does mom's age when the child was born link to how severe the autism is?

They looked at two things: IQ scores and parent ratings on the Child Behavior Checklist. They ran the numbers to see if older moms had kids with lower IQ or more social problems.

No link at all. Kids of 20-year-old moms looked the same as kids of 40-year-old moms on both IQ and parent-rated social severity.

The team concluded that maternal age is not a crystal ball for autism prognosis.

Robinson et al. (2011) asked the same question in the general population and also found nothing. Their null result backs up this clinic sample, giving a two-for-one replication.

Capio et al. (2013) clashes. In a huge Finnish cohort they saw advanced maternal age raise risk for Asperger's and PDD. The difference: they tracked autism risk at birth, not severity after diagnosis. Risk and severity are not the same thing.

Shire et al. (2022) extends the story. They swapped calendar age for 'biologic age' based on mom's DNA marks. Slight cognitive dips showed up in babies, hinting that age itself may matter less than how fast mom's cells are aging.

When parents ask, 'Will my age make my child's autism worse?' you can say the weight of evidence says no. Skip age-based scare talk. Spend your session time on skill-building programs, not on maternal age guilt.
