The diffuse cerebellar dysfunction as a permanent neurological sequela of organophosphate poisoning has not yet been reported in the published literature. We report a diffuse cerebellar dysfunction as a permanent manifestation of organophosphate poisoning. A 55-year-old man diagnosed with acute organophosphate poisoning was brought to the emergency room of our hospital. He had slurred, monotonous scanning speech with irregularly distributed articulatory deficits, and prominent bilateral limb ataxia. He presented left-beating spontaneous nystagmus with a downbeat component and strong downbeating nystagmus after head shaking. He also showed saccadic hypometria with a normal saccadic velocity at fixed horizontal saccades and symmetrically impaired horizontal smooth pursuit on both sides. The poisoning of organophosphate poisoning may lead to a diffuse permanent cerebellar dysfunction as a neurological sequela event. KCI Citation Count: 1
