Functional neurological disorder (FND) sits at the intersection of psychiatry and neurology, causing disabling motor and sensory symptoms despite intact peripheral pathways. FND may reflect altered precision weighting within neural systems, such that the brain generates the dysfunction it predicts. Stress is among the most consistent precipitants; however, how it produces functional symptoms remains mechanistically unspecified. The present account proposes that FND arises from the overprecision...
