What is cataplexy?

Cataplexy is a sudden loss of muscle tone, triggered by strong emotions such as laughter, anger, or surprise. It can cause the person to collapse or drop to the ground, but they remain conscious and aware of their surroundings. Cataplexy is a symptom of narcolepsy, a chronic sleep disorder that causes excessive daytime sleepiness (EDS).

What causes cataplexy?

Cataplexy is caused by a disruption in the brain's ability to regulate sleep-wake cycles. In people with narcolepsy, the brain does not produce enough of a neurotransmitter called hypocretin (also known as orexin), which is involved in regulating sleep and wakefulness. This deficiency can lead to a variety of symptoms, including cataplexy, EDS, and sleep paralysis.

How is cataplexy treated?

Cataplexy can be treated with medications such as stimulants, antidepressants, and sodium oxybate. These medications can help to reduce the frequency and severity of cataplexy attacks and improve overall sleep quality. In addition to medications, lifestyle changes such as avoiding caffeine and alcohol, and getting regular exercise can also help to reduce symptoms.

Living with cataplexy

Cataplexy can be a challenging and embarrassing condition, but there are many ways to manage it and live a full and active life. There are a number of support groups and resources available to people with cataplexy and narcolepsy, which can provide information and support to those living with these conditions.
