Abstract: | We studied the effects of higher mental activity on the EEG, i.e., neuropsychological EEG activation (NPA), in patients with juvenile myoclonic epilepsy (JME). Thirty patients with JME underwent a conventional EEG recording and EEG recording during performance of a battery of twelve neuropsychological tasks, which involved decision making, reading, calculations, constructive activities and drawing. Twenty-three JME patients (76.6%) responded (i.e., showed EEG activation) to at least one neuropsychological task (p = 0.003). Four neuropsychological tasks, two involving the use of the hands and two without manual involvement, were associated with a high frequency of EEG activation (40-60% of JME patients), although statistical analysis did not reveal any one test as the most significant for NPA activation. Neuropsychological EEG activation, using a variety of tasks both manual and non-manual, is a useful tool in evaluating patients with JME. |
