Insomnia Related to Psychiatric Disorders
Psychiatric disorders increase the risk for insomnia. Insomnia, including abnormal sleep cycles or excessive sleepiness, is often a prominent symptom of schizophrenia, and it is a common complaint for people suffering from generalized anxiety disorder (GAD) and depression. Treatment for the psychiatric disorder often helps resolve difficulty sleeping.
Insomnia diminishes the quality of life, reduces cognitive function, and affects overall health. People with chronic insomnia are four times as likely to experience major depression and are twice as likely to develop an anxiety disorder or substance abuse problem.
People with insomnia are involved in automobile crashes more frequently. In many cases, insomnia affects job performance and leads to frequent absences from work or school.
