Early Glymphatic Dysfunction May Predict Psychosis Risk

Researchers tracking 85 people with 22q11.2 deletion syndrome over 25 years found that impaired brain waste clearance (glymphatic function) in childhood is linked to later psychosis. Those who developed psychotic symptoms showed weaker glymphatic development (lower ALPS index) and an excitatory/inhibitory imbalance, suggesting brain-cleaning failures early in life may contribute to psychosis and could offer avenues for preventive interventions.
