Somnology
Pharmacological treatments are used to chemically treat sleep disturbances such as insomnia or excessive daytime sleepiness. The kinds of drugs used to treat sleep disorders include: anticonvulsants, anti-narcoleptics, anti-Parkinsonian drugs, benzodiazepines, non-benzodiazepine hypnotics, and opiates as well as the hormone melatonin and melatonin receptor stimulators. Anticonvulsants, opiates, and anti-Parkinsonian drugs are often used to treat restless legs syndrome. Furthermore, melatonin, benzodiazepines hypnotics, and non-benzodiazepine hypnotics may be used to treat insomnia. Finally, anti-narcoleptics help treat narcolepsy and excessive daytime sleepiness.
Neuroscience of sleep
Studying sleep disorders is particularly useful as it gives some clues as to which parts of the brain may be involved in the modified function. This is done by comparing the imaging and histological patterns in normal and affected subjects. Treatment of sleep disorders typically involves behavioral and psychotherapeutic methods though other techniques may also be used. The choice of treatment methodology for a specific patient depends on the patient's diagnosis, medical and psychiatric history, and preferences, as well as the expertise of the treating clinician. Often, behavioral or psychotherapeutic and pharmacological approaches are compatible and can effectively be combined to maximize therapeutic benefits.
