中老年人神经系统疾病的遗传学因素目前尚未引起足够重视,但是这个问题必须进行专门研究。这是因为:第一,这个年龄患者在总群体中越来越多;第二,了解中老年人疾病的遗传学特征有利于阐明神经遗传学的一般规律。研究中老年人神经系统疾病的遗传学因素有以下几个方向;第一个方向是研究接近 The genetic factors of neurological diseases in the elderly have not been given sufficient attention at present, but this issue must be specially studied. This is because: First, there are more and more patients of this age in the general population. Second, understanding the genetic characteristics of the diseases in the elderly is good for elucidating the general laws of neurogenetics. There are several directions for studying the genetic aspects of neurological disorders in the elderly; the first is to approach the study
