This extensively revised second edition provides a comprehensive overview of transient global amnesia (TGA). First, it deals with the history of TGA before moving on to clinical and diagnostic features and differential diagnosis. Subsequent chapters then discuss the investigation and predisposing and precipitating factors for TGA before attempting to synthesise these many strands in order to formulate ideas about the pathogenesis of TGA. Each of the chapters is devoted to a practical and structured overview of the particular topic, with use of case studies to illustrate the material. Based in part on the author’s experience of TGA cases over 20 years and in part on a review of the published literature, this book will hopefully enlighten clinicians from a broad range of medical backgrounds on the clinical features, investigation, and pathogenesis of TGA.
