Most people think that autism is a disorder of the brain. But the skin may play a role, too, a new study suggests. Nerve cells in the skin are abnormal in mice with mutations in autism-related genes, leading to altered touch perception, scientists report. This trouble sensing touch may influence the developing brain in a way that leads to social deficits and anxiety later in life.
"Autism Tied to Aberrant Sense of Touch" is from the July 9, 2016 issue of Science News.
