title: [Insomnia disorder].
abstract: The rate of those who have sleep problems increases due to aging. In Japan, a super-aging society, insomnia is a common disease. It is reported that the ratio of insomniacs over sixty year-old is 29.5 %. The sleep disturbance in the elderly is caused by multi factors, such as physiological, physical, psychosociological, psychiatric, and pharmacological factors. According to the latest diagnostic criteria of sleep disorders, ICSD-3, the concept of primary or secondary insomnia was abolished. Instead of that, insomnia is categorized by the duration of disease, and general doctors can diagnose sleep disorders more easily than the past. However, it is not necessary to consider the pathophysiological mechanism, there is a concern that the clinical level of insomnia treatment might decline in quality.
