Cataplexy is a sudden, temporary loss of muscle tone triggered by strong emotions such as laughter, surprise, anger, or excitement. Attacks can range from mild facial drooping to full-body collapse while the person remains fully conscious. Management typically involves identifying and avoiding personal triggers, maintaining consistent sleep schedules, and, in many cases, prescription medications like sodium oxybate or SSRIs under medical supervision.
Because cataplexy is often linked to narcolepsy and can mimic other neurological conditions, understanding your symptoms early is critical to getting the right treatment. If you or a loved one are experiencing sudden muscle weakness tied to emotional moments, don't wait—take a free, instant, online symptom check to gain clarity on what might be happening and confidently plan your next steps.
