Obstructive sleep apnoea and depression--diagnostic and treatment implications

Area of Science:

• Neurology
• Psychiatry
• Sleep Medicine

Background:

• Obstructive sleep apnoea (OSA) is a prevalent sleep disorder associated with significant morbidity, including psychiatric conditions.
• There is growing evidence highlighting a strong connection between OSA and depression.
• Sleep disturbances, particularly REM sleep alterations, are characteristic of both OSA and depressive disorders.

Purpose of the Study:

• To explore the relationship between obstructive sleep apnoea and depression.
• To highlight the overlapping neuro-vegetative symptoms and REM sleep disturbances common to both conditions.
• To emphasize the clinical implications for diagnosing and treating patients with resistant depression and sleep disorders.

Main Methods:

• Review of existing literature and studies investigating the link between OSA and depression.
• Analysis of shared symptomatology, focusing on neuro-vegetative features and REM sleep patterns.
• Examination of treatment implications for co-occurring OSA and depression.

Main Results:

• A statistically significant association between OSA and depression is confirmed by numerous studies.
• The neuro-vegetative symptoms of depression frequently mirror those of OSA.
• OSA significantly disrupts REM sleep, a feature also prominent in depressive disorders.

Conclusions:

• OSA should be considered in the differential diagnosis of chronic or treatment-resistant depression.
• Effective treatment of OSA can potentially facilitate the management of underlying depressive disorders.
• Continuous positive airway pump (CPAP) therapy for OSA presents a theoretical avenue for treating depression.
