In research news, scientists from the National
Institute of Allergy and Infectious Diseases (NIAID) report for the first

Scientists believe they may have identified the cause of the debilitating sleep disorder narcolepsy in humans. A new study shows a dramatic reduction - up to 95 percent - in the number of neurons containing a substance called hypocretins in the brains of people with narcolepsy compared to control brains.

The researchers hypothesize that the pronounced loss of these neurons could be caused either by a neurodegenerative process or an autoimmune response. We've provided a fact sheet regarding narcolepsy in this issue.
