WC231: Phenylketonuria (PKU) and Mental Health
LIVE: Wellbeing Compass Topic #231 — Phenylketonuria and Mental Health. PKU is an inherited metabolic condition: the body cannot properly break down phenylalanine, which builds to harmful levels unless controlled by lifelong low-protein diet and medical formula. Newborn screening since the 1960s catches most cases early — yet psychological burden remains.
A 2016 systematic review and meta-analysis in Developmental Neuropsychology pooled 8 study arms totaling 889 adults with PKU. Researchers found pooled anxiety prevalence 22% (95% CI 11–36%) and pooled depression prevalence 18% (95% CI 8–31%) — both higher than general-population estimates from structured diagnostic interviews. Even among adults treated early and consistently from birth, rates stayed elevated. The page stresses: check in about mood and stress, not just diet adherence. Multilingual + crisis resources retained.
