Background And Purpose:
The aim was to evaluate the relationship between insomnia and psychiatric disorders in general hospital inpatients.
Patients And Methods:
Information about insomnia was collected using a structured and codified questionnaire adapted from a previously validated one in Brazil. For Diagnostic and Statistical Manual of Mental Disorders IV (DSM-IV) psychiatric diagnosis, the Portuguese version of the International Neuropsychiatric Interview (MINI) was used.
Results:
Out of the 200 patients interviewed, 56.5% complained of insomnia, and 50.0% suffered from at least one psychiatric disorder. Major depressive episode (MDE) (P<0.001), generalized anxiety disorder (P=0.025) and suicide risk (P=0.034) were associated with insomnia (univariate analysis). The results of the multivariate analysis showed that only MDE had a statistically significant association with insomnia (OR=3.6; 95% CI=1.9-6.9).
Conclusions:
This study found a high prevalence of psychiatric disorders and insomnia in a general hospital population and found that insomnia can be a marker for MDE.

Multiple factors contribute...
Management of Insomnia
CNS Depressants: Barbiturates and Benzodiazepines
Sedatives and Hypnotics Drugs: Miscellaneous Agents
Melatonin congeners like ramelteon (Rozerem) and tasimelteon (Hetlioz) selectively bind to melatonin receptors (MT1 and MT2) and thus mimic the actions of melatonin, a hormone that regulates sleep-wake cycles. Tasimelteon is primarily used for non-24-hour sleep-wake disorder, common in blind patients. They are also used to treat conditions like insomnia...
