ATHOPHYSIOLOGY Narcolepsy is a relatively rare sleep disorder it is known as an"orphan disease" this means it a disease that affects less than 5 per 10,000 people within a community. Narcolepsy is a sleep disorder which affects the brains' ability to regulate the normal sleep-wake cycle. This can lead to symptoms such as disturbed night-time sleep and excessive sleepiness throughout the day SYMPTOMS Automatic behaviour involves carrying on with an activity even though you have no recollection of it. You are not aware of your actions and don't perform them well. For example, if you're writing before falling asleep, you may scribble rather than form wordsMany narcoleptics report problems with food. This could be over or under eating or being intolerant to many standard food groups. There appears to be an increased incidence of hyper activity in children diagnosed with narcolepsy. Their activities seem to speed up rather than slow down STATISTICS 185 patients who had received regular treatment were enrolled in the study (NA-CA, n=83; NA w/o CA, n=48; IHS w/o LST, n=54). Patients were asked to complete questionnaires including the Short Form-36 Health Survey (SF-36), the Epworth Sleepiness Scale (ESS), and items concerning psychosocial and environmental variables. All three diagnostic groups had significantly lower scores for most SF-36 domains compared with the Japanese normative data, and the ESS score was significantly reduced with treatment. Multiple logistic regression analyses revealed that several SF-36 domains were associated with the ESS score; autonomy in controlling own job schedule, experience of divorce or break up with a partner due to symptoms, experience of being forced to relocate or being dismissed due to symptoms, and perception of support from others.
