PANDAS PANS Strep and REM Sleep Disorder

Fascinating. REM sleep disorder seen in 87% of patients with PANS. PSG may be helpful in PANDAS / PANS. Note this is a case series. -JR

" RBD has been reported to occur only rarely in children. However, in this consecutive case series of 15 children with PANS, we observed 4 children (27%) met RBD criteria and noted evidence of REM sleep motor disinhibition in 8 others (53%). Only two patients (13%) had a normal PSG, and PANS symptoms had remitted for one of those children."

Rapid Eye Movement Sleep Abnormalities in Children with Pediatric Acute-Onset Neuropsychiatric Syndrome (PANS)


Current Knowledge/Study Rationale: REM sleep behavior disorder (RBD) has been demonstrated across all ages, but has been reported to occur only rarely in childhood. Among adults, RBD is associated with neurodegenerative conditions; its significance in pediatric patient populations is unknown. Demonstrating abnormalities of sleep architecture in children with PANS may provide additional insights into the etiopathogenesis of the neuropsychiatric syndrome.
Study Impact: This case series reports on sleep-related motor disturbances among children with PANS, particularly in the REM state. Pediatric RBD is likely not generated by the same mechanisms that often predict the onset of a neurodegenerative disorder among adults, and may instead be a useful marker of transient central nervous system disturbance in select cohorts.
