What is the optimal management strategy for insomnia associated with major depressive disorder (MDD)?

From the Guidelines

The most effective way to manage insomnia in depression is through a combination of cognitive behavioral therapy for insomnia (CBT-I) and addressing the underlying depression, with medication options such as sedating antidepressants or non-benzodiazepine sleep medications used judiciously. Managing insomnia in depression requires a multifaceted approach that includes behavioral changes, medication, and addressing the underlying depression. First-line treatments include CBT-I, which teaches sleep hygiene practices like maintaining consistent sleep schedules, avoiding caffeine and alcohol before bedtime, creating a comfortable sleep environment, and limiting screen time, as supported by the American Academy of Sleep Medicine systematic review, meta-analysis, and GRADE assessment 1. For medication options, sedating antidepressants like trazodone (25-100mg at bedtime), mirtazapine (7.5-15mg at bedtime), or doxepin (3-6mg at bedtime) can treat both depression and insomnia simultaneously.

Some key points to consider in managing insomnia in depression include:

• The importance of CBT-I as a first-line treatment, as recommended by the American College of Physicians clinical practice guideline 1
• The use of sedating antidepressants or non-benzodiazepine sleep medications, with careful consideration of their potential risks and benefits
• The need to address the underlying depression, as improving mood often leads to better sleep
• The importance of regular exercise, mindfulness meditation, and relaxation techniques in improving sleep quality
• The potential for sleep problems and depression to create a vicious cycle, with poor sleep worsening depression and depression disrupting sleep.

Overall, a comprehensive approach that addresses both the insomnia and the underlying depression is crucial for effective management, as supported by the American Academy of Sleep Medicine systematic review, meta-analysis, and GRADE assessment 1.

From the Research

Management of Insomnia in Depression

The management of insomnia in depression can be approached in several ways, including:

• Choosing a sedating antidepressant agent such as trazodone, mirtazapine, or agomelatine 2
• Starting with a non-sedating antidepressant and switching to a more sedating antidepressant or offering a hypnotic or cognitive-behavioral therapy as adjunctive treatment if insomnia persists 2
• Using cognitive behavioral therapy for insomnia (CBT-I) as a first-line treatment, especially for patients with depression, post-traumatic stress disorder (PTSD), and alcohol dependency 3

Cognitive Behavioral Therapy for Insomnia (CBT-I)

CBT-I has been shown to be an effective treatment for insomnia in patients with depression, with moderate to large effect sizes for reduction of insomnia severity 3, 4, 5

• CBT-I can be used as a stand-alone treatment for depression, particularly in cases where antidepressant medications are not ideal 5
• In-person CBT-I has the most supporting evidence for its efficacy, although treatment effects may not be additive with those of antidepressant medications 5
• Factors promoting adherence to CBT-I include a preference for non-pharmacological treatment, rapid improvement, and support from relatives and therapists 6

Treatment Considerations

When treating insomnia in depression, it is essential to consider the following:

• The potential for antidepressant medications to worsen sleep complaints 2
• The importance of addressing sleep disturbances to prevent relapse into depression 3, 5
• The need for individualized treatment approaches, taking into account the patient's preferences and needs 6
