Sleep Disorders

Abstract

THE early years of the modern sleep-research era, which followed the discovery of rapid eye movements (REMs), were devoted primarily to the investigation and definition of normal sleep.1 , 2 As the field expanded with each discovery, clinicians began to realize the potential value of evaluating, in the sleep laboratory, the clinical conditions in which sleep was disrupted or altered or both. Consequently, the number and scope of studies relating to clinically pertinent aspects of sleep have greatly increased in recent years.3 4 5 This review discusses the advances in evaluating and treating sleep disorders and other clinical conditions in which sleep is disturbed. . . .
