Sleep initiation and maintenance disorders
In medicine, sleep initiation and maintenance disorders, including insomnia, are "disorders characterized by impairment of the ability to initiate or maintain sleep. This may occur as a primary disorder or in association with another medical or psychiatric condition."[1][2]
Epidemiology/causes
There are many underlying associations[3][4] including psychiatric disorders[5][4].
Diagnosis
While an extremely thorough history, including observations from sleeping partners or household members, is the proper starting point, a polysomnogram is often needed for the differential diagnosis.
Treatment
| Treatment | Outcome at 6 months | |
|---|---|---|
| Responders | Remitters | |
| 6 weeks of CBT | 55% | 40% |
| 6 months of CBT | 63% | 44% |
| 6 months of CBT 6 weeks of zolpidem |
81% | 68% |
| 6 months of CBT 6 months of zolpidem |
65% | 42% |

Treatment options for geriatric patients have been reviewed.[7]
Non-drug treatment
No-drug treatments such as light therapy, exercise, and sleep-hygiene modification have been reviewed.[8]
A combination of education, sleep hygiene, exercise, and light therapy helped patients with Alzheimer's disease in the NITE-AD randomized controlled trial.[9]
Indirect evidence suggests a warm bath may help.[10]
Exercise, perhaps by raising body temperature, may help.[10]
Medications
Pharmacological interventions for sleepiness and sleep disturbances caused by shift work has been reviewed by the Cochrane Collaboration.[11]
GABA agonists
These medications are agonists of the gamma aminobutyric acid.
Nonselective BZ1 and BZ2 agonists
BZ1 selective agonists
These medications include zopiclone, eszopiclone, zolpidem, and zaleplon. Overall, the benefit of these medications is small.[12]
In treating persistent insomnia in adults, 6 weeks of zolpidem 10 mg nightly along with weekly sessions of cognitive behavioral therapy followed by 6 months of monthly sessions and no medications yielded the most remission of insomnia in a randomized controlled trial.[6]
In geriatrics, the benefits of zolpidem for insomnia to not clearly exceed the drug toxicity.[13][14]
The benefit of eszopiclone may not be strong.[15]
Melatonin agonists
These may increase sleep by less than 30 minutes.[11]
Ramelteon is one available agonist. Its magnitude of benefit may be small among outpatients.[15]
Tasimelteon can help transient insomnia due to shift changes related to employment.[16]
