Insomnia, a public health issue, is linked to psychiatric disorders. Treating insomnia with cognitive behavioral therapy improves both insomnia and comorbid psychiatric symptoms, suggesting insomnia is a transdiagnostic factor.
Area of Science:
- Psychiatry
- Sleep Medicine
- Public Health
Background:
- Insomnia is a significant public health concern.
- Insomnia frequently co-occurs with various psychiatric disorders.
- Historically viewed as a symptom, insomnia's role is now seen as more complex.
Purpose of the Study:
- To explore the relationship between insomnia and psychiatric disorders.
- To investigate insomnia as a potential transdiagnostic factor in mental health.
Main Methods:
- Review of epidemiological and experimental studies.
- Analysis of randomized controlled trials (RCTs) for cognitive behavioral therapy for insomnia (CBT-I).
Main Results:
- Studies indicate insomnia is associated with the onset and progression of psychiatric disorders.
- RCTs demonstrate that CBT-I improves insomnia and comorbid psychiatric symptoms.
- Evidence suggests insomnia acts as a transdiagnostic process.
Conclusions:
- Insomnia is more than a symptom; it's a transdiagnostic factor in psychiatric conditions.
- Targeting insomnia, particularly with CBT-I, can benefit overall psychiatric health.

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...
