A cohort of 33 people at risk for Huntington's disease (HD), applying for genetic testing, were tested with a battery of neuropsychological tests covering attentional, visuospatial, learning, memory, and planning functions. A psychiatric rating scale, SCL-90R, was also applied, mainly as a control, since cognitive dysfunction could be ascribed to functional disorders as well as neurodegenerative processes. Self-rating did not indicate any psychiatric symptoms in carriers or non-carriers. However, significantly inferior cognitive functioning in the gene carriers was disclosed by the neuropsychological tests. Primarily, attentional, learning, and planning functions were affected. It is concluded that premorbid cognitive decline occurs in HD.
一组33名有亨廷顿舞蹈症(HD)风险且申请基因检测的人,接受了一系列涵盖注意力、视觉空间、学习、记忆和计划功能的神经心理学测试。还应用了一种精神科评定量表SCL - 90R,主要作为对照,因为认知功能障碍可能归因于功能紊乱以及神经退行性过程。自评未显示携带者或非携带者有任何精神症状。然而,神经心理学测试揭示基因携带者的认知功能明显较差。主要是注意力、学习和计划功能受到影响。结论是HD患者病前会出现认知衰退。
