What Is Cataplexy?

Cataplexy is a sudden loss of muscle tone, often triggered by strong emotions, such as laughter, anger, or fear. It is a symptom of narcolepsy, a chronic sleep disorder that affects the body's ability to regulate sleep and wakefulness.

Cataplexy can range in severity from a brief weakening of the muscles to a complete collapse of the body. During an attack of cataplexy, a person may experience:

* Dropping their head or jaw

* Slurred speech

* Difficulty walking or standing

* Double vision

* Hallucinations

* Paralysis

Cataplexy can be a dangerous symptom, as it can lead to falls and injuries. It is important for people with narcolepsy to be aware of their triggers and to take precautions to avoid situations that may cause an attack.

Treatment for cataplexy typically involves medication to control the symptoms and reduce the risk of attacks. Some people may also benefit from lifestyle changes, such as avoiding caffeine and alcohol and getting regular exercise.
