Brief report: parental reporting of regression in children with pervasive developmental disorders.
Parent-reported regression is common but usually reflects slow or stalled skills rather than true loss.
01Research in Context
What this study did
The team asked parents if their child ever lost skills.
They compared answers from families of kids with autism to families of kids with other delays.
The study was small and used parent memory, not direct testing.
What they found
More autism parents said "yes, my child lost skills."
When doctors looked closer, most kids had never truly lost a skill.
Parents had seen slower or stuck progress and called it regression.
How this fits with other research
Pearson et al. (2018) and Thurm et al. (2018) show the same twist.
Big reviews say parent stories sound dramatic, but watching kids every day finds only small, slow losses.
Mount et al. (2011) and Bhaumik et al. (2009) still find real regression in about one of every four kids with ASD.
Warnes et al. (2005) adds: whether parents recall regression or early onset does not change later IQ or autism severity.
Why it matters
When a parent says "my child talked and then stopped," listen, then dig.
Ask what was actually said, when, and if anyone else saw it.
Use today’s skills, not the story, to plan goals.

03Original abstract
Information on age and nature of the onset of autism and other developmental disorders was obtained through review of parent completed developmental history; in addition information on the child's early development, diagnostic information, and information on parent characteristics was also obtained. In this relatively large series of cases the parents of children with autism were more likely than parents of children with other developmental disorders to report possible loss of developmental skills. However, the question of actual skill loss was complicated since in some cases parents also had reported even earlier developmental delays or a pattern more of developmental stagnation than clear loss of abilities. Only a few children exhibited a clear and unequivocal loss of developmental skills.
