Pediatric acute-onset neuropsychiatric syndrome (PANS)

Pediatric acute-onset neuropsychiatric syndrome (PANS) is a neuropsychiatric syndrome still under research, leading to rapid onset Obsessive-compulsive disorder (OCD) and/or tics in children and adolescents.[1][2][3] It may be either connected to Group A streptococcal infections (PANDAS sub-group)[4][5] or[clarification needed] caused by immunologic reactions[6] to other pathogens (PITANDS sub-group)[7][7][8][9][10] affecting the basal ganglia.[11][12] This portion of the brain is responsible for mediating cognition, emotion, and movement. Research into the etiology of obsessive-compulsive disorder has identified dysfunctions of the basal ganglia as a key factor for the onset of OCD.[13] A similar syndrome in adults is known as Post-inflammatory Brain Syndrome (PIBS).[14]

Differential diagnostics

As there are other conditions that may have similar presentation, diagnostic workup of individuals suspected of PANS should exclude Sydenham's chorea, lupus erythematosus, acute disseminated encephalomyelitis, and Tourette syndrome.

Treatment

Treatment of OCD or Tourette possibly caused by PANS is generally the same as the standard therapies for OCD and Tourettes (symptomatic treatment).[15] It has, however, been observed that children with PANS appear to be unusually sensitive to the side-effects of SSRIs.[5][16] Treatment with antibiotics,[17][18] and immune-based therapeutic approaches are still considered as experimental.[5][19] Early and consequent treatment appears to be of importance to avoid chronification and lifelong persistence.[3][4][20]
