What are the treatment options for sleep disorders?

Treatment Options for Sleep Disorders

Cognitive Behavioral Therapy for Insomnia (CBT-I) should be considered the first-line treatment for chronic insomnia disorder due to its strong evidence base, long-lasting effects, and minimal side effects. 1

Types of Sleep Disorders

Sleep disorders can be broadly categorized into:

• Insomnia - difficulty falling asleep and/or maintaining sleep at least 3 times per week for at least 4 weeks, accompanied by distress 1
• Sleep disturbance and/or excessive sleepiness - including conditions like obstructive sleep apnea (OSA) and narcolepsy 1
• Parasomnias - disorders of arousal and REM sleep 2

Treatment Options for Insomnia

Behavioral and Psychological Treatments

Multicomponent Therapies:

• Cognitive Behavioral Therapy for Insomnia (CBT-I): Combines cognitive therapy strategies with education about sleep regulation, stimulus control instructions, and sleep restriction therapy. Typically delivered over 4-8 sessions with sleep diary monitoring. This has the strongest evidence and is recommended as first-line treatment. 1

• Brief Therapies for Insomnia (BTIs): Abbreviated versions of CBT-I (1-4 sessions) emphasizing behavioral components, including education about sleep regulation and a tailored behavioral prescription based on stimulus control and sleep restriction therapy. 1

Single-Component Therapies:

• Stimulus Control: Instructions designed to extinguish the association between bed/bedroom and wakefulness, including going to bed only when sleepy, getting out of bed when unable to sleep, using bed only for sleep and sex, waking at the same time daily, and avoiding daytime napping. 1

• Sleep Restriction Therapy: Limits time in bed to match the patient's sleep duration, initially restricting time in bed and then gradually increasing or decreasing based on sleep efficiency thresholds. 1

• Relaxation Therapy: Structured exercises to reduce somatic tension (e.g., abdominal breathing, progressive muscle relaxation) and cognitive arousal (e.g., guided imagery, meditation). 1

• Sleep Hygiene Education: General recommendations about lifestyle and environmental factors that may promote or interfere with sleep. Not recommended as a standalone treatment due to insufficient evidence. 1

Recent research suggests that the most critical components of CBT-I are cognitive restructuring, third-wave components, sleep restriction, and stimulus control, while relaxation procedures may be counterproductive and sleep hygiene education alone is not essential. 3

Delivery Methods for Behavioral Treatments

• In-person therapist-led programs have been found most beneficial 3
• Internet-based CBT-I has shown clinically significant improvements 1
• Group therapy formats are also effective 1

Pharmacological Treatments

Pharmacological treatments are generally considered second-line after behavioral interventions:

• Non-benzodiazepine receptor agonists (e.g., zolpidem, eszopiclone) may be effective for short-term use but carry risks including complex sleep behaviors, next-day impairment, and CNS depression. 4, 5

• Low-dose doxepin has received favorable recommendations for short-term use. 1

• Benzodiazepines are not generally recommended due to potential for withdrawal syndrome with REM rebound and other adverse effects. 1, 2

Treatment for Other Sleep Disorders

Obstructive Sleep Apnea (OSA)

• Continuous positive airway pressure (CPAP) is the primary treatment 1
• Weight loss and exercise should be recommended 1
• Surgery or oral appliances may be options for some patients 1

Restless Legs Syndrome (RLS)

• Dopamine agonists are effective in reducing RLS symptoms 1
• Gabapentin (calcium channel alpha-2-delta ligand) can help improve sleep in RLS 1
• Check ferritin levels - levels below 45-50 ng/mL indicate a treatable cause of RLS 1

Special Considerations

Insomnia with Comorbidities

• CBT-I is effective for patients with comorbid mental disorders including depression, PTSD, alcohol dependency, and mixed diagnoses 6
• Effect sizes for reduction of insomnia severity are moderate to large and persist at follow-up 6
• CBT-I can also improve symptoms of the comorbid condition, particularly depression and PTSD 6

Cancer Survivors

• Psychosocial interventions including CBT-I are recommended for sleep disturbances in cancer survivors 1
• Physical activity, particularly yoga, may improve sleep in cancer survivors 1

Common Pitfalls and Caveats

• Relying solely on sleep hygiene education is a common mistake. While sleep hygiene principles are important, they are insufficient as a standalone treatment for chronic insomnia. 1

• Overuse of pharmacological treatments without trying behavioral approaches first. Medications carry risks including complex sleep behaviors, next-day impairment, and dependence. 4, 5

• Inadequate assessment of comorbid conditions. Sleep disturbances may be a manifestation of an underlying physical or psychiatric disorder that should be evaluated if insomnia doesn't improve after 7-10 days of treatment. 1, 5

• Patient expectations of immediate results. Unlike medications, behavioral treatments typically produce gradual improvements, but the benefits are more durable. Setting realistic expectations is important. 1

• Limited availability of trained providers. Despite strong evidence for CBT-I, there remains a shortage of trained practitioners, making it an underutilized treatment. 7
