Cataplexy
lack of muscle tone or muscle weakness, and in some cases complete paralysis of the voluntary muscles
Cataplexy is a sudden and temporary loss of muscle tone and control that occurs in people with narcolepsy. Narcolepsy is a neurological disorder that affects the brain’s ability to regulate sleep-wake cycles, leading to excessive daytime sleepiness and other symptoms, including cataplexy.
Cataplexy often takes the form of weakening or collapsing of muscles in response to strong emotions such as laughter, anger, or surprise. These episodes can range from mild weakness of the facial muscles to complete loss of muscle tone and control that can cause the person to fall to the ground. The loss of muscle control typically lasts a few seconds to a few minutes and can occur spontaneously or be triggered by emotional stimuli.
Cataplexy can be embarrassing and disruptive to daily activities, and it can be dangerous if it happens during activities that require physical control, such as driving or operating machinery. There are treatments available to manage cataplexy, including certain medications and lifestyle modifications.
If you or someone you know experiences cataplexy, it is important to speak to a doctor or sleep specialist to receive a proper diagnosis and develop a treatment plan.
