Of these, neurological ones are prominent and, when present, usually consist of ataxia, nystagmus, or dysarthria. Phenytoin toxicity in patients with previous strokes may present as a “re-stroke” syndrome. This paper reports a rare but recognizable complication in a patient in whom reversible monoplegia, a focal neurological deficit, developed during long-term phenytoin therapy for grand mal seizures.
