Epileptic chorea: Another window into neural networks?

Paroxysmal abnormalities of motor or non-motor function are defined as epileptic when they co-occur with specific patterns of organized electrical activity as measured by scalp electroencephalography (EEG). Certain forms of abdominal pain and migraine may be therefore epileptic [1]. Stereotypical movements at night can be the result of mesial frontal epilepsy, despite a negative EEG and prolonged focal paroxysmal dystonia can result from unilateral putaminal hemorrhage [2]. Short-lasting motor activity categorized clinically as dystonia or athetosis, meeting criteria for paroxysmal non-kinesigenic dyskinesia (PNKD), may result from caudate nucleus rather than cortical discharges [3,4].
