Patterns: Autism and Brain Growth Studied
By ERIC NAGOURNEY
Two new studies report that from an early age, the brains
and heads of autistic children develop differently from those
of other children.
But researchers said it was unclear what, if anything, might
be learned from the findings.
In separate studies appearing in the current issue of Neurology,
Dr. Stephen R. Dager and Dr. Elizabeth H. Aylward, both of
the University of Washington School of Medicine, found that
brain growth in autistic children was more rapid in
early years.
Among the 3- and 4-year-old autistic children they examined,
Dr. Dager and his colleagues found cerebral volumes that were
on average 10 percent larger than they were in children with
typical brain development.
Dr. Aylward and her colleagues also found that the brains
grew abnormally quickly among young autistic children but
that the growth slowed around age 12, just as the brains of
children who are not autistic generally experience spurts
of growth.
An accompanying editorial said that no one had ever demonstrated
a connection between brain size and brain function, and argued
that until research methods were improved, "the observations
of slight variations in parts of the brain
remind the casual observer of phrenology".
