Criteria for a broadened syndrome of acute onset
obsessive compulsive disorder (OCD) have been proposed by a National Institutes of Health scientist and her colleagues. The syndrome, Pediatric Acute-onset Neuropsychiatric Syndrome (PANS), includes children and teens that suddenly develop on-again/off-again OCD symptoms or abnormal eating behaviors, along with other psychiatric symptoms — without any known cause.
PANS expands on
Pediatric Autoimmune Neuropsychiatric Disorder Associated with Streptococcus (PANDAS), which is limited to a subset of cases traceable to an
autoimmune process triggered by a strep infection. A clinical trial testing an immune-based treatment for PANDAS is currently underway at NIH and Yale University (see below).
