抑郁症是一种最普遍,但又不容易被认识的精神疾病。到目前为止,有许多人对抑郁症认识不清,往往使病情拖延,影响治疗。西方国家统计资料表明,每1000人之中有3~5人患抑郁症。而且,近年来抑郁症的患病率有上升的趋势,尤其是在城市,这种情况应引起我们的重视。抑郁症的主要表现是情绪低落、思维迟缓或郁郁不乐。此时,甚至对一切,包括平常喜欢的工作或娱乐都丧失兴趣,或者是体验不到工作、生活或娱乐中的快乐感。病人看起来疲乏倦怠、表情悲伤,甚至双眉紧锁,整个生活充满了无精打采和懒散的气氛。患者需要费很大的精力才能完成日常的工作,并尽量… 相似文献

Endophenotypes are heritable quantitative traits that are associated with disease liability, can be measured in both affected
and unaffected individuals, and provide much greater power to localize and identify risk genes for mental illness than does
affection status alone. Traditionally, endophenotypic markers for psychiatric illnesses include in vivo neuroanatomic and functional magnetic resonance imaging measurements and indices of neurocognitive abilities. However, neurocognitive
and neuroimaging measures are by no means the only classes of endophenotypes that could be useful for identifying genes for
mental illness. Given the advantages of endophenotype-based strategies for elucidating the genetic underpinnings of psychiatric
disorders, it would seem prudent to develop a wide range of putative endophenotypes. In order for a measure to be considered
a valid endophenotype, it must meet a number of criteria. Specifically, the trait must (1) have moderate to high heritability,
(2) be associated with the illness, (3) be independent of clinical state, and (4) impairment must co-segregate with the illness
within a family, with non-affected family members showing impairment relative to the general population. While each of these
criteria is critical, the heritability and co-segregation requirements are really what differentiate an endophenotype from
a simple biomarker. At this time, one requires an experimental design that includes families to demonstrate both heritability
and co-segregation. The assertion that novel endophenotypes can not be fully established without family data does not preclude
work in unrelated individuals, rather that unrelated samples will only be able to nominate potential candidate endophenotypes
that subsequently need to be confirmed in family-based experiments. 相似文献
