The Clinical and Neuroelectrophysiological Study of Corticobasal Degeneration
OBJECTIVE: To explore the clinical and neuroelectrophysiological features of patients with corticobasal degeneration(CBD). BACKGRUND: To date, there is no systematic presentation of patients diagnosed as CBD in our country. METHODS: 29 patients with CBD were examined symptoms, signs, CT/MRI, SPECT and electrophysiologic studies in detail. RESULTS: The results demonstrated asymitrical Parkinsonian manifestations were present in all, cortical dysfunction in 86%. other movement disorders in 75%, 21 cases showed asymmetrical atrophy in CT/MRI and 25 in SPECT were hypoperfused on the fronto-parital regions contralateral to the affected limbs 19 cases in EEG showed asymitrical slow waves; Surface EMG showed .that myoclonus in 15 occurred on the action; SEPs revealed c-reflexes enhanced and without giant SEP; patients had no pre-myoclonus spike on JLA. 29 patients showed normal CMCT in MEPs. DISCUSSION: The most common manifestation of CBD was asymmetric Parkinsonian features, followed by cortical dysfunction and other movement disorders. Brain imaging showed fronto-parietal abnormalities contralateral to the affected side. The study of electrophysiology showed enhanced cortical excitability and pyramidal tract intact. CONCLUSION: CBD is characterazed by a slowly progressive disease with both cortical and basal ganglionic dysfunction.
