What Causes Narcolepsy?
Research suggests that the cause of narcolepsy is a
lack of the chemical in the brain called hypocretin. This chemical stimulates
brain cells and helps promote wakefulness. It is not known why hypocretin is
missing in people who have narcolepsy. Some factors that may work together to
cause a lack of hypocretin include:
- Infection
- Loss of certain brain cells due to brain injury,
toxins, and/or the bodys destruction of its own tissues (autoimmune
reaction)
- Changes in hormones
- Stress
One out of 10 people with narcolepsy and cataplexy
has a close relative with the same symptoms. This suggests that some people may
inherit the tendency to develop narcolepsy. |
