延伸阅读
强迫状态一种个人并不希望、不愿接受、但又不能自主抗拒的异常心理现象。它可以是某种观念（强迫思维）、意向（强迫意向）或行为（强迫行为）。患者明知是不必要去想、去做的，甚至认为是不正常的、不合理的事情却不能对之加以控制，而重复出现在自己的意识中，暂时成为压倒一切的优势心理状态。倘若患者强制对抗或试图摆脱这种状态，就会引起严重的焦虑或恐惧，致使不得不停止正在进行的日常活动，直到所要进行的某种强迫动作或行为已经完成，或强迫思考的问题得到解决，才能恢复原来的日常活动。如果使这种患者更换新的生活环境或处在高度紧张的境遇中，其强迫性现象可暂时减轻。J. -┵.-D. 埃斯基罗尔首次注意到强迫状态，并于1838年描述了一例强迫怀疑的症状,并把它归入单狂,其后，许多学者对此进行研究并提出各自的论点。例如S.弗洛伊德认为，强迫症和恐怖症须加以区分；И.Π.巴甫洛夫认为强迫症属于高级神经活动的局部障碍，应把它从精神衰弱中分出来。具有易感素质和强迫性人格特征的人较易发生强迫状态，强烈的精神因素也可使人格健全者产生强迫状态。强迫状态主要见于强迫性神经症，也可见于某些抑郁症和早期精神分裂症。
