What is cataplexy and what are the symptoms?
Cataplexy is the sudden loss of muscle tone, causing slurred speech or muscle weakness. These symptoms can last for several minutes.
What causes cataplexy?
Cataplexy is often associated with type 1 narcolepsy and isn’t something that can be controlled. It is often triggered by strong emotions, including fear, anxiety, anger, laughter, or excitement. While not every person diagnosed with type 1 narcolepsy has it, those that do have cataplexy can experience episodes anywhere from one to two a year or up to several episodes in a day.
How is cataplexy diagnosed and how do you treat it?
Cataplexy is often diagnosed in conjunction with narcolepsy. To determine if the symptoms of cataplexy are part of a narcolepsy diagnosis, sleep diaries and sleep studies (polysomnography) are often used. A Multiple Sleep Latency Test (MSLT), otherwise known as a daytime nap study, may also be used.
While there is no cure for cataplexy, patients diagnosed with this condition can learn to modify their reactions and activities to minimize the episodes. Studies have also shown that certain SSRIs or antidepressants may help minimize symptoms.
If you are suffering with cataplexy symptoms, please talk with your healthcare provider so that a plan for managing the condition can be established. To make an appointment to discuss your sleeping concerns, call our West Lakes Sleep Center at 515.875.9555.
