Cataplexy is a sudden loss of muscle tone that can lead to weakness or paralysis, often triggered by strong emotions such as laughter, excitement, or surprise. It is commonly associated with narcolepsy, a sleep disorder that affects the brain's ability to regulate sleep-wake cycles. During a cataplectic episode, a person may experience a brief collapse or inability to move, while remaining fully aware of their surroundings. The duration of cataplexy can vary from a few seconds to a couple of minutes. Although it can be alarming, cataplexy itself is not life-threatening. Treatment options include medications that help manage symptoms and improve overall quality of life for those affected.
