Treatment of Sleep Disturbances in Older Adults

Initial Assessment and Treatment

Cognitive behavioral therapy for insomnia (CBT-I) should be the first-line treatment for sleep disturbances in older adults, with pharmacotherapy reserved only for cases where CBT-I has failed, using the lowest effective doses for the shortest duration possible, as recommended by the American College of Physicians 1
Evaluate all medications that may disrupt sleep, including β-blockers, bronchodilators, corticosteroids, decongestants, diuretics, SSRIs, and SNRIs, in older adults with sleep disturbances 1, 2
Screen for primary sleep disorders such as obstructive sleep apnea (24% prevalence), restless legs syndrome (12% prevalence), and periodic limb movements (45% prevalence) in older adults 3, 4
Assess sleep-impairing behaviors including excessive daytime napping, prolonged time in bed, insufficient physical activity, evening alcohol consumption, and late heavy meals in older adults 1
Identify medical comorbidities such as pain, nocturia, gastroesophageal reflux, and neurodegenerative disorders that exacerbate sleep disruption in older adults 3, 5

CBT-I is recommended as first-line therapy due to proven efficacy with sustained effects for up to 2 years and minimal side effects compared to medications, as recommended by the American Academy of Sleep Medicine 1, 2
Sleep restriction/compression therapy, stimulus control therapy, sleep hygiene education, and relaxation techniques are effective components of CBT-I for older adults 1, 6
Bright light therapy, structured physical and social activity, and environmental modifications can help regulate circadian rhythms in older adults with sleep disturbances 7, 8

Pharmacotherapy should only be considered when CBT-I alone has been unsuccessful, using shared decision-making that discusses benefits, harms, and costs of short-term medication use, as recommended by the American Geriatrics Society 1
Ramelteon (melatonin receptor agonist) is the preferred first choice for sleep onset insomnia due to safer profile and minimal adverse effects 1, 2, 6
Low-dose doxepin (3-6 mg) is effective for sleep maintenance insomnia with minimal side effects 1, 2

Benzodiazepines should be avoided due to higher risk of falls, cognitive impairment, dependence, and worsening dementia in elderly patients, as recommended by the American Geriatrics Society 1, 2, 6
Over-the-counter antihistamines (diphenhydramine) should be avoided in elderly patients due to anticholinergic effects and lack of efficacy data 1, 2, 6
Sedating antidepressants (trazodone, amitriptyline, mirtazapine) should only be used when comorbid depression or anxiety exists, as there is no systematic evidence for effectiveness in primary insomnia and risks outweigh benefits 1, 2
