# Insomnia in seasonal affective disorder: considering the use of benzodiazepines with a focus on lormetazepam

## TL;DR

This paper reviews the use of benzodiazepines, especially lormetazepam, for treating insomnia in seasonal affective disorder, highlighting their potential benefits and the need for more clinical trials.

## Contribution

The paper specifically highlights lormetazepam as a potential treatment for insomnia in SAD, emphasizing its role in addressing an unmet clinical need.

## Key findings

- Insomnia is a common and impactful symptom in seasonal affective disorder.
- Benzodiazepines, particularly lormetazepam, show potential as short-term treatments for insomnia in SAD.
- More clinical trials are needed to confirm the efficacy and safety of lormetazepam for this condition.

## Abstract

Seasonal affective disorder (SAD) occurs in two main forms: winter-pattern SAD, associated with depressive symptoms during shorter, darker days; and summer-pattern SAD, linked to mood disturbances during longer, hotter days. SAD may develop into a chronic condition with recurring depressive episodes. Risk factors for SAD include geographic latitude, age, gender, genetic predisposition, and lifestyle. Sleep disturbances, such as insomnia, hypersomnia, and circadian rhythm disruptions, are common and can amplify emotional symptoms.

This review explores the clinical features and management strategies for insomnia associated with SAD, focusing on the potential of benzodiazepines (BZDs), in particular lormetazepam.

Controversies surround current nonpharmacological and pharmacological strategies for managing sleep disorders in SAD. This review emphasizes the importance of using more effective treatments for insomnia associated with SAD, currently an unmet need. In particular, clinical evidence supports the potential benefits of intermittent hypnotic BZDs to treat insomnia. Among the BZDs, short-term or intermittent use of lormetazepam is an effective treatment option in the management of insomnia.

Insomnia associated with SAD is an important symptom to monitor because it impacts the patient’s quality of life. BZDs, including lormetazepam, are a standard short-treatment option for insomnia that could improve the sleep symptoms associated with SAD. Comparative clinical trials of the efficacy and safety of lormetazepam in this patient population are required to confirm this.
