Electroencephalographic findings in neuroacanthocytosis.

This study reports the electroencephalographic findings in two siblings with neuroacanthocytosis. Slowing of the background activity with diffuse slow waves was the main finding in the daytime EEG. All-night polysomnographic recordings were characterized by high voltage slow activity during drowsy state and REM sleep. One patient with an average of 40 episodes of apnea per night of sleep was treated with imipramine and showed respiratory improvement.
