Epilepsy evoked by eating: the role of peripheral input.

A 13-year-old boy with documented epilepsy evoked by eating, a rare form of reflex epilepsy, experienced only partial control with anticonvulsant medication. Repetitive peripheral sensory input was necessary to evoke seizures in this patient. The seizures remitted completely after he lost several fingers in an accident. Decreased sensory input presumably altered the seizure threshold so that the seizures were eliminated.
