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.
The SART, MWT, and ESS all had good reliability, obtained for the SART and MWT using two to three sessions in 1 day. The ability to distinguish responders from nonresponders, classified using the CGI-C score, was high for all measures, with a high performance for the SART (r = 0.61) and the ESS (r = 0.54).
Severe daytime sleepiness may require treatment with high doses of stimulant medication, and sometimes a combination of stimulants may be needed. Rare or infrequent cataplexy and other associated symptoms may not require any drug treatment, or treatment on an "as needed" regimen may be adequate.
