A marked decrease in motivation to initiate and sustain purposeful activities, common in schizophrenia and severe depression.
From Greek 'a-' (without) + Latin 'volitio' (willing, choosing), from 'velle' (to wish, to will).
Avolition isn't laziness — it's when the brain's motivation engine shuts down, and even basic tasks like showering feel impossibly hard.
