Pediatric acute-onset neuropsychiatric syndrome

Pediatric Acute-Onset Neuropsychiatric Syndrome (PANS) is a term used to describe children who are hypothesized to have "abrupt, dramatic onset of obsessive-compulsive disorder (OCD) or severely restricted food intake" coincident with the presence of two or more neuropsychiatric symptoms; it is a proposed modification to the PANDAS hypothesis.
Classification
PANS is postulated as a subset of pediatric onset obsessive-compulsive disorder (OCD). It is distinguished from traditional childhood onset OCD by the severity, abruptness and dramatic onset of symptoms. they consider these treatments to be reserved for "critically ill patients".
History
* 2012: Swedo and Leckman publish "From Research Subgroup to Clinical Syndrome: Modifying the PANDAS Criteria to Describe PANS (Pediatric Acute-onset Neuropsychiatric Syndrome) where sudden onset OCD is the primary distinguishing features and tic disorders are moved to one of the coincident neuropsychiatric symptoms. Swedo explains that the team modified the PANDAS criteria to clarify the presentation and "eliminate etiologic factors".<ref name=Swedo2012 />
