The perspective of management of sleep disorders in Japan

Abstract

SummaryIncreases in psychosocial stress and disruption of the biological clock due to irregular sleep-wake schedules as well as an increase in the elderly population have resulted in an increase in sleep disorders, most notably insomnia. In order to manage insomnia, correction of a poor sleep environment is of primary importance. We now have many good GABA A receptor agonists such as benzodiazepines and cyclopyrrolones (zopiclone) for use as hypnotics, but to achieve improvements in nocturnal sleep and restoration of daytime functions, short- or ultra-short acting hypnotics are recommended. Zopiclone has been reported to show weaker effects on sleep architecture than other benzodiazepines and does not exacerbate mild or moderate sleep apnea syndrome. Some patients are therapeutic-dose dependent on hypnotics or anxiolytics without showing detectable side effects. It may be possible for some insomniacs, particularly forelderly people, to use the minimum necessary dose of hypnotics to achieve good sleep and live a happy life from the standpoint of good quality of life.
