Conversion hysteria differs from hysteria in that it arises suddenly, rather than being a lifelong disorder. It is monosymptomatic rather than polysymptomatic, and is seen in men almost as frequently as in women. La belle indifférence, when present, is a useful clue to diagnosis. Other clues are ambiguity in reporting of the symptoms, medically inconsistent symptoms and hysterical personality features. Treatment may include removing the patient from a stressful environment and removing the "payoff" yielded by the illness. A confrontation with the patient is generally to be avoided.
转换性癔症与癔症的不同之处在于，它突然发作，而非一种终身性疾病。它是单症状而非多症状的，在男性和女性中出现的频率几乎相同。若存在“泰然漠视”，则是诊断的有用线索。其他线索包括症状报告含糊不清、医学上不一致的症状以及癔症性人格特征。治疗可能包括让患者脱离压力环境，并消除疾病带来的“益处”。通常应避免与患者对峙。
