Sluggish Brain Drain in Childhood Signals Psychosis Risk in 22q11.2 Syndrome
A longitudinal study of children with 22q11.2 deletion shows that early impairment of the brain’s glymphatic waste-clearance system is linked to later psychotic symptoms, likely via hippocampal glutamate excess and reduced GABA inhibition; findings highlight a potential early biomarker and suggest interventions focused on sleep and inflammation to delay or prevent a first psychotic episode.
