When a profoundly autistic son or daughter suddenly freezes, stops communicating, or starts acting out, it can put a program spot at risk. In this solo episode, host Mike Carr walks through the Autism Science Foundation's two-page guide to Catatonia, "a serious but treatable condition that affects movement, speech, behavior, and automatic functioning." He covers the signs to watch for, why a change from your child's baseline matters, and what to bring to your physician.
