Visual evoked potentials (VEPs) to full-field and half-field stimulation were recorded in a large sample of patients with Huntington's disease (n = 36) and subjects at risk (first-order offspring, n = 55) using a checkerboard pattern reversal stimulus. Whereas a clear diminution of the amplitudes found confirmed earlier findings in patients with Huntington's disease, further alterations of VEP wave forms consisted in the absence of asymmetric hemisphere lateralization to half-field stimulation (i) and severe distortion with amplification of the early NPN/PNP complexes (ii). Considering at least two different abnormal parameters necessary to represent a reliable indicator of the disease, 24 patients (67%) and 14 (25%) of the persons at risk exhibited pathological results. In contrast, only 2 among 36 patients (5%) but 30 (55%) among the offspring exhibited normal results. The diagnostic and predictive value of the investigation of VEPs in Huntington's disease is discussed.
使用棋盘格图案翻转刺激,在大量亨廷顿病患者(n = 36)和有患病风险的受试者(一级后代,n = 55)中记录了全视野和半视野刺激的视觉诱发电位(VEP)。虽然所发现的振幅明显降低证实了早期对亨廷顿病患者的研究结果,但VEP波形的进一步改变包括:(i)半视野刺激时缺乏不对称半球侧化;(ii)早期NPN/PNP复合波放大并严重畸变。考虑到至少需要两个不同的异常参数才能作为该疾病的可靠指标,24名患者(67%)和14名有患病风险者(25%)呈现出病理结果。相比之下,36名患者中只有2名(5%)结果正常,但后代中有30名(55%)结果正常。文中讨论了VEP检查在亨廷顿病中的诊断和预测价值。
