据英国文献报道,“发作性跌倒”这一典型的老年病症状,估计占所有老年人跌倒中的四分之一,但美国医生在跌倒的讨论中,却很少承认它。发作性跌倒是否为一种独立的疾病,还是多种疾病的一种症状?在美国一直未被重视和缺乏研究。本文综述关于发作性跌倒的典型特征,重点是讨论这一常见的但并未被多数人认识的症状的流行病学、病因学以及临床处理。 According to the British literature, the symptoms of “episodic fall”, a typical symptom of geriatrics, are estimated to account for a quarter of all elderly people who fall, but American doctors rarely acknowledge it in the discussion of falls. Is episodic fall a symptom of an individual disease or a multitude of illnesses? Has not been valued in the United States and is lack of research. This article reviews the typical features of episodic falls, focusing on the epidemiology, etiology, and clinical management of this common but not most commonly recognized symptom.
