Sleep Medication Recommendations for Patients with Dementia
For patients with dementia and sleep disturbances, non-pharmacological interventions should be used as first-line treatment, and clinicians should avoid using sleep-promoting medications due to increased risks of adverse events in this population. 1
First-Line Approaches (Non-Pharmacological)
Cognitive Behavioral Therapy for Insomnia (CBT-I)
- CBT-I has shown robust improvements in sleep quantity and quality for both young and older adults 1
- Components include:
- Sleep restriction
- Stimulus control
- Cognitive restructuring
- Sleep hygiene education
- Relaxation techniques
Light Therapy
- Suggested for elderly patients with dementia who have irregular sleep-wake rhythm disorder (ISWRD) 1
- Protocol: White broad spectrum light therapy (2500-5000 lux) positioned ~1 meter from participants, 1-2 hours in duration, between 9:00-11:00 AM, for 4-10 weeks
- While evidence is very low quality, light therapy may improve behavioral symptoms even when total sleep time doesn't increase 1
Physical and Social Activities
- Physical activities may slightly increase total nocturnal sleep time and sleep efficiency 2
- Social activities may slightly improve total nocturnal sleep time 2
- Regular daytime physical activity should be encouraged to help regulate sleep-wake cycles 3
Sleep Medications to AVOID in Dementia
Strong Recommendation Against
- The American Academy of Sleep Medicine strongly recommends against using sleep-promoting medications to treat elderly patients with dementia who have ISWRD 1
- Hypnotic medications increase risks of falls, confusion, and other adverse events in this population 1
- Medications with anticholinergic properties should be minimized in older persons 1
Melatonin Considerations
- The evidence suggests clinicians should avoid using melatonin as a treatment for ISWRD in older people with dementia 1
- However, strategically timed melatonin is suggested for ISWRD in children/adolescents with neurologic disorders 1
Special Considerations
Sleep Apnea Assessment
- A careful sleep history, including assessment of sleep time and symptoms of sleep apnea, should be included in the assessment of any patient at risk for dementia 1
- Patients with suspected sleep apnea should be referred for polysomnography and/or sleep specialist consultation 1
- Adults with sleep apnea should be treated with continuous positive airway pressure (CPAP), which may improve cognition and decrease dementia risk 1
Sleep Hygiene Practices
- Maintain consistent sleep-wake schedules
- Create a sleep environment conducive to sleep (quiet, dark, comfortable temperature)
- Limit screen time before bed
- Avoid caffeine and alcohol close to bedtime
- Target 7-8 hours of sleep per night 1
Monitoring and Follow-up
- Assess sleep parameters within 2-4 weeks of starting any intervention 4
- Monitor for side effects, particularly daytime sedation, falls, and cognitive changes
- Consider referral to a sleep specialist if sleep disturbances persist 4
Pitfalls and Caveats
- Combining interventions that have sedating effects increases risk of falls, confusion, and respiratory depression 4
- Despite the inclusion of multiple randomized controlled trials, there is a lack of conclusive evidence for non-pharmacological interventions for sleep problems in people with dementia 2
- The multifactorial nature of sleep problems in dementia requires addressing primary sleep disorders, comorbid conditions, and medications that may impact sleep 3
- While non-pharmacological approaches are preferred, they may require more time and resources to implement effectively
In summary, for patients with dementia and sleep disturbances, non-pharmacological approaches should be prioritized, with particular emphasis on CBT-I, light therapy, and physical/social activities. Sleep medications should be avoided due to significant risks of adverse effects in this vulnerable population.
