Cognitive behavioral therapy for insomnia
The first step in treating insomnia with CBT-I is to identify the underlying causes of the insomnia. People with insomnia should evaluate or have their sleep patterns evaluated and take into account all possible factors that may be affecting the person's ability to sleep. This would involve keeping a sleep diary or journal for a couple weeks. The journal will help to identify patterns of thoughts or behaviors, stressors, etc. that could be contributing to the person's insomnia.
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.
