Abstract

A 7.5-year-old girl, with infantile neuroaxonal dystrophy (INAD), showed a gradual deterioration from 16 months; at age 5 years she was bedridden, with severe tetraplegia, strabismus, nystagmus and optic atrophy, and dementia. From age 5.5 years, she had paroxysmal tonic events. Video-polygraphic recordings disclosed two different kinds of motor events: (a) epileptic tonic seizures, in wakefulness and sleep, associated with autonomic changes and ictal EEG discharges; and (b) nonepileptic prolonged clusters of brief tonic spasms, without ictal modifications of the EEG. Both motor events were characterized by a minimal and clinically similar tonic contraction of the upper extremities. Video-polygraphic studies are mandatory for a correct paroxysmal event classification and treatment in INAD patients.
