Around 3 million people worldwide suffer from narcolepsy or bouts of sleepiness and sleep attacks that can affect their ability to have a normal life. There is no cure for the disorder, and few clues about its causes. But now, a new study suggests it could be an autoimmune disease.
Narcolepsy – extreme bouts of sleepiness that can strike at any time – affects around 1 in 2,000 people in the US. A new study raises concerns about its diagnosis in adolescents, after it identified marijuana in the urine of some teenagers who had symptoms consistent with narcolepsy.
