title: Ictal video-EEG analysis of infantile neuroaxonal dystrophy.
abstract: A 4-year-old boy with infantile neuroaxonal dystrophy (INAD) showed gradual deterioration from age 9 months with seizure development at age approximately 36 months. Sural nerve biopsy performed at age 42 months confirmed INAD. The seizure, recorded by video-EEG, consisted of a series of symmetrical tonic spasms of both upper extremities after a prodrome period of staring and akinesis. Each spasm had phonation, and episodic autonomic symptoms such as hypertension and flushing of the face occurred throughout the seizure. Ictal EEG with each tonic spasm, showed diffuse 1-s, irregular sharp and high-voltage slow wave complexes followed by desynchronization.
