Causes of Narcolepsy
Researchers continue to seek out the root cause of narcolepsy. Currently, the general consensus is that genetics, accompanied by an environmental trigger of some sort – a virus, for example – may affect brain chemicals and contribute to the disorder.
Scientists have recently discovered that people with narcolepsy are lacking in hypocretin, a chemical in the brain that activates arousal and regulates sleep. Narcoleptics generally do not have as many Hcrt cells or neurons that secrete hypocretin, inhibiting their ability to fully control their alertness and sleep cycles.
Heredity appears to be a factor in narcolepsy, but environmental triggers also play a strong role. Research is also investigating these triggers.
Narcolepsy affects many areas of life:
- Physical well-being and safety
- Mental health
- Social and professional relationships
- Intimate relationships
- Memory and attention
