Insomnia and Excessive Daytime Sleepiness (EDS)
Adjustment insomnia
Acute emotional stressors (eg, job loss, hospitalization, a death in the family) can cause insomnia. Symptoms typically remit shortly after the stressors abate; insomnia is usually transient and brief. Nevertheless, if daytime sleepiness and fatigue develop, especially if they interfere with daytime functioning, short-term treatment with hypnotics at bedtime is warranted. Persistent anxiety may require specific treatment.
