Insomnia
While insomnia is a common symptom of depression, antidepressants are effective for treating sleep problems whether or not they are associated with depression. While all antidepressants help regulate sleep, some antidepressants such as amitriptyline, doxepin, mirtazapine, and trazodone can have an immediate sedative effect, and are prescribed to treat insomnia. Amitriptyline and doxepin both have antihistaminergic, anticholinergic, and antiadrenergic properties, which contribute to both their therapeutic effects and side effect profiles, while mirtazapine's side effects are primarily antihistaminergic, and trazodone's side-effects are primarily antiadrenergic. Mirtazapine is known to decrease sleep latency (i.e., the time it takes to fall asleep), promoting sleep efficiency and increasing the total amount of sleeping time in people with both depression and insomnia.
Idiopathic hypersomnia
In addition to medications, "behavioral approaches and sleep hygiene techniques are recommended, although they have little overall positive impact on this disease." "Planned naps are unhelpful, as they are both long and unrefreshing."
Although behavioral approaches have not been shown to improve EDS, the goal, as in CBT (cognitive behavioral therapy), is often to help patients learn to reduce their negative emotional responses (e.g. frustration, anger, depression) to their disease symptoms. Furthermore, because idiopathic hypersomnia "may lead to marriage breakdown, extensive counseling for the patient's partners, educating them about the symptomatology and treatment options, must be part of a comprehensive management plan... Education of relatives, friends, and colleagues helps the patient to function much better with this incurable disease."
