How to manage insomnia during Electroconvulsive Therapy (ECT)?

Managing Insomnia During Electroconvulsive Therapy (ECT)

For patients undergoing ECT who experience insomnia, cognitive behavioral therapy for insomnia (CBT-I) should be the first-line treatment, with low-dose trazodone (25-50mg) as an adjunctive option if needed. 1, 2

Assessment and Understanding Insomnia During ECT

• ECT combined with antidepressants (such as venlafaxine) has only modest effects on insomnia symptoms, with most patients experiencing some degree of residual insomnia that requires targeted treatment 3
• Sleep diary data should be collected before and during ECT treatment to track insomnia symptoms, including sleep latency, wake time after sleep onset, and total sleep time 1
• Regular reassessment should occur every few weeks until insomnia appears stable or resolved 1

First-Line Treatment: Cognitive Behavioral Therapy for Insomnia (CBT-I)

CBT-I is recommended as the primary intervention for insomnia during ECT due to its proven effectiveness and safety profile. Key components include:

• Stimulus control therapy: Designed to extinguish negative associations between bed and wakefulness by going to bed only when sleepy, maintaining regular schedules, avoiding naps, and leaving bed if unable to sleep within 20 minutes 1, 4
• Sleep restriction: Initially limits time in bed to match actual sleep time, aiming for >85% sleep efficiency, with weekly adjustments based on sleep efficiency 1, 4
• Cognitive therapy: Targets dysfunctional beliefs about sleep that perpetuate insomnia, such as "I can't sleep without medication" 1, 4
• Relaxation training: Includes progressive muscle relaxation to lower somatic and cognitive arousal that interferes with sleep 1, 4

Pharmacological Options When CBT-I Is Insufficient

If CBT-I alone is inadequate for managing insomnia during ECT:

• Low-dose trazodone (25-50mg) is preferred as it has been shown to be safe when used concurrently with ECT, with no significant increase in cardiovascular complications 2, 5
• Low-dose doxepin (3-6mg) is an alternative if trazodone is ineffective, with minimal anticholinergic effects at low doses 2
• Short/intermediate-acting benzodiazepine receptor agonists (zaleplon, zolpidem, eszopiclone) may be considered, but use caution as they may affect seizure parameters during ECT 1

Important Considerations and Precautions

• Allow sufficient time between administration of hypnotics and ECT to minimize potential interference with seizure parameters 6
• Avoid adding multiple sedating medications simultaneously, which increases risk of daytime sedation 2
• Monitor for changes in ECT efficacy when using benzodiazepines or z-drugs, as they may potentially affect seizure threshold or duration 6
• Sleep hygiene alone is insufficient and should always be combined with other therapies 1, 4

Monitoring and Follow-up

• Reassess sleep patterns using sleep logs after 2-4 weeks of intervention 2
• Evaluate improvement in sleep efficiency, total sleep time, and daytime functioning 2
• Continue to monitor insomnia symptoms throughout the ECT course, as changes in ECT and medication may affect sleep patterns 1, 7
• If insomnia persists despite these interventions, consider referral to a sleep specialist 2

By implementing this approach, clinicians can effectively manage insomnia during ECT while minimizing potential interference with treatment efficacy and patient comfort.
