Insomnia in Psychiatric Disorders
- 1.7k Downloads
Management of insomnia without a basic understanding of the possible underlying psychiatric disorders might result in an inadequate, if not hazardous outcome. Insomnia is listed in the fourth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV) as a symptom of several psychiatric disorders.
Insomnia related to other DSM-IV mental disorders was found to be as high as 77%. In more than 50%S of the cases, the diagnosis was a depressive disorder. In general, 57% of individuals reporting insomnia have a psychiatric disorder or will develop one within a year. Anxiety seems to play a key role in the development of insomnia. Second to anxiety disorders, depression is strongly associated with the development of insomnia. Depression is considered as a possible precipitating mechanism but even more likely as a consequence of insomnia.
