Seizures trigger autism-like behaviors in mice

by  /  23 October 2014

Mice with an extra copy of the autism-linked gene UBE3A show abnormal social behavior after experiencing recurrent seizures. The findings, presented Tuesday at the Autism Consortium Research Symposium in Boston, provide one possible explanation for why seizures and autism often go hand in hand.
