Narcolepsy, the rare and long-term sleep disorder, may have a new way to be diagnosed — with the help of a unique type of blood test. The findings come from Alberto De la Herran-Arita who published a paper after discovering distinctions in the blood of people who have narcolepsy. The Huffington Post reported that his team of researchers found that autoimmune diseases may be linked to narcolepsy and that in the future, a simple blood test might indicate narcolepsy for that individual.
Excessive sleepiness, particularly excessive daytime sleepiness, is the hallmark sign of hypersomnia. Hypersomnia can also be characterized by prolonged sleep at night.
