PANDAS

Pediatric Autoimmune Neuropsychiatric Disorders Associated with Streptococcal infections. This diagnosis is used to describe a set of children who have a rapid onset of obsessive-compulsive disorder (OCD) and/or tic disorders such as Tourette syndrome (TS), infections such as “strep throat” and scarlet fever. The proposed link between infection and these disorders is an autoimmune reaction, where antibodies produced by the infection interfere with neuronal cells.
