Various brain areas in both cortical as well as subcortical locations are involved in pathological laughter. Pathological laughter may be seen as a prodromal symptom or acute manifestation or late sequel of stroke. Various other neuropsychiatric conditions attribute to stroke. It is often difficult to ascertain the cause of pathological laughter in the presence of multiple brain pathologies. Here, we highlight a case of a 55-year-old female, who had multiple episodes of stroke and subdural hematoma, presented with pathological laughter and other behavioral abnormalities.
皮层及皮层下的多个脑区都与病理性笑有关。病理性笑可能被视为中风的前驱症状、急性表现或晚期后遗症。其他各种神经精神疾病也可归因于中风。在存在多种脑部病变的情况下，往往很难确定病理性笑的病因。在此，我们重点介绍一例55岁女性患者，她有多次中风和硬膜下血肿病史，表现出病理性笑及其他行为异常。
