Some research also reveals a possible mutation with hypocretin in addition to the deficiency, making it more difficult for the body to regulate normal sleep cycles.
The discovery of the role of hypocretin in narcolepsy is the most recent and one of the most significant discoveries in the study of the disorder.
Researchers conducting examinations of human and animal brains surmise that a deficiency of cells called hypocretin may be a cause for narcolepsy.
Narcolepsy is a disorder in the nervous system of the body that occurs when fewer amounts of a protein called hypocretin are made in the brain.
Orexin-Another name for hypocretin, a chemical secreted in the hypothalmus that regulates the sleep/wake cycle.
