Common sleep disorders in the elderly: diagnosis and treatment.

Insomnia and daytime sleepiness in an elderly patient may be a normal consequence of aging, the result of a primary sleep disorder, or an adverse effect of medication or medical illness. Effective management requires a differential diagnosis. Adjustment sleep disorder, primary snoring, inadequate sleep hygiene, and mood disorders are common in the aged. The physician needs to review the patient history, including stressful events, medications, medical illness, and the possible presence of a psychiatric disorder. Treatment often involves behavioral changes and conservative use of medications, including antidepressants or benzodiazepines.
