Computed topographic electroencephalographic study in left hemiplegic patients with higher cortical dysfunction.
Computed topographic electroencephalography (EEG) was performed on patients with right hemispheric injury due to cerebral infarction to investigate the relationship of wave form pattern with neurologic and neuropsychologic data and activities of daily living (ADL). Neurologic signs, unilateral spatial neglect, motor impersistence, and constructional apraxia were found to have no relation to the wave form pattern of computed topographic EEG. In patients with abnormalities detected by the "Mini-Mental State" examination (MMSE) or the "Kanahiroi" test, and in patients with abnormalities in word fluency, extensive slowing of EEG frequency was commonly observed ipsilateral to the side of the lesion or bilaterally, and the ADL were frequently poor. In contrast, among the patients with slow waves and retained alpha waves, the MMSE, "Kana-hiroi" test, word fluency, and ADL were less abnormal. Computed topographic EEG may thus be a useful tool to evaluate neuropsychological status in rehabilitation patients with cerebral infarction.
