Undoubtedly the commonest psychiatric conditions seen in patients from the tropics are reactive depression and hysterical illness. These may both be seen as responses to stress, often over a prolonged period. Although typical depressive and hysterical syndromes are seen in all races, severe tiredness seems to be the principal hysterical symptom amongst Europeans as opposed to bizarre somatic symptoms in Negroes and Asians. Headaches are an important depressive sign in Negroes and Asians. Diarrhoea and abdominal pains may be linked directly to anxiety and depression or may emerge as an unconscious defence against insoluble problems.
毫无疑问，热带地区患者中最常见的精神疾病是反应性抑郁症和癔症。这两种疾病都可被视为对压力的反应，而且往往是长期的反应。尽管所有种族中都会出现典型的抑郁和癔症综合征，但严重疲劳似乎是欧洲人主要的癔症症状，而黑人和亚洲人的主要症状则是怪异的躯体症状。头痛是黑人和亚洲人重要的抑郁症状。腹泻和腹痛可能与焦虑和抑郁直接相关，也可能是对无法解决的问题的一种无意识防御反应。
