Abstract

Syncope, or the sudden loss of consciousness, is a common presenting symptom for evaluation by neurologists. It is not a unique diagnosis but rather a common manifestation of disorders with diverse mechanisms. Loss of consciousness is typically preceded by a prodrome of symptoms and sometimes there is a clear trigger. This article discusses several cases that illustrate the various causes of syncope. Reflex syncope is the most common type and includes neurally mediated, vasovagal, situational, carotid sinus hypersensitivity, and atypical forms. Acute and chronic autonomic neuropathies and neurodegenerative disorders can also present with syncope.

摘要

晕厥，即意识突然丧失，是神经科医生评估时常见的就诊症状。它并非一种独特的诊断，而是多种机制紊乱的常见表现。意识丧失通常先有前驱症状，有时还有明确的诱因。本文讨论了几例说明晕厥各种病因的病例。反射性晕厥是最常见的类型，包括神经介导性、血管迷走性、情境性、颈动脉窦过敏及非典型形式。急慢性自主神经病变和神经退行性疾病也可表现为晕厥。
