The causes of depression are unique to each individual and very complex. Tendencies toward depression can run in families, pointing to a genetic link in many cases. The roots of a depressive episode may lie in one's childhood environment, or in a traumatic event in later life. It is generally believed, however, that neurochemical imbalances and disruptions in the brain are above all responsible for triggering depressive symptoms. The good news is that there are several effective treatments available to fight depression, and that most sufferers begin feeling better within several weeks of beginning therapy.
憂郁癥的肇因因人而異,而且十分復(fù)雜。憂郁癥的傾向會世代相傳,在許多情況下與基因有關(guān)。其根源可能是由于幼年環(huán)境,或是在晚年經(jīng)歷了痛苦而難忘的事件。然而,尤其是神經(jīng)化學(xué)的失衡和腦神經(jīng)分裂被公認(rèn)為引發(fā)憂郁癥的原因。好消息是現(xiàn)在已有數(shù)種有效的治療方法問世,而且大部分患者在最初數(shù)周的治療后即會有所好轉(zhuǎn)。
