Sleep, that familiar yet inexplicable condition of repose in which consciousness is in abeyance, is obviously not abnormal, yet it is connected with a number of interesting and common irregularities, some of which approach serious extremes. Furthermore, certain neurological conditions have special types of sleep disorders as common features. The psychologic and physiologic benefits of sleep are of paramount importance, and it is increasingly recognized that disruption of sleep increases the risks for several diseases, including stroke, hypertension, and coronary disease.
