Over the last few years data have accumulated suggesting that there may be genetic and biologic risk factors for suicide. This paper reviews studies from clinical populations, twins, the Amish, as well as data from the Iowa-500 and Danish-American adoption studies which suggest that there may be a genetic factor predisposing to suicide. The paper also reviews neurochemical data from cerebrospinal fluid, urine and postmortem studies which suggest that diminished central serotonin and dopamine may be implicated in suicidal behavior.
在过去几年中，积累的数据表明，可能存在自杀的遗传和生物学风险因素。本文回顾了来自临床人群、双胞胎、阿米什人以及爱荷华500研究和丹麦-美国收养研究的数据，这些研究表明可能存在一种导致自杀的遗传因素。本文还回顾了来自脑脊液、尿液和尸检研究的神经化学数据，这些数据表明中枢5-羟色胺和多巴胺水平降低可能与自杀行为有关。
