Cataplexy

Cataplexy is a medical condition which often affects people who have narcolepsy, a sleep disorder whose principal signs are EDS (Excessive Daytime Sleepiness), sleep attacks, and disturbed night-time sleep. Cataplexy is sometimes confused with epilepsy, where a series of flashes or other stimuli cause superficially similar seizures.

The term cataplexy originates from the Greek kata, meaning down, and plexis, meaning a stroke or seizure.


Cataplexy Symptoms


Cataplexy manifests itself as muscular weakness which may range from a barely perceptible slackening of the facial muscles to the dropping of the jaw or head, weakness at the knees, or a total collapse. Usually the speech is slurred, vision is impaired (double vision, inability to focus), but hearing and awareness remain normal. These attacks are triggered by strong emotions such as exhilaration, anger, fear, surprise, orgasm, awe, embarrassment and laughter.

Cataplexy Diagnosis


Cataplexy in severe cases can cause vital signs to be hard to detect without a continuous auditory pulse oximeter (a well-known heart monitor). As an anecdotal example, one Allison Burchell, a sufferer of severe Cataplexy, has been sent to the morgue three times.


Cataplexy Treatment


Despite its relation to narcolepsy, in most cases, cataplexy must be treated differently and separate medication must be taken. For many years, cataplexy has been treated with tricyclic antidepressants such as imipramine, clomipramine or protriptyline. However these can have unpleasant side-effects and so have been generally replaced by newer drugs such as Effexor, a more recent antidepressant. Xyrem, the brand-name of the compound (sodium)gamma-Hydroxybutyrate GHB, has been shown to treat not only cataplexic attacks, but in narcoleptics, it has also been shown to significantly reduce daytime sleepiness. All drugs have side effects, be sure to know what they are and any adverse reactions they might have before taking any sleep disorder or cataplexy medications. Cataplexy can also be treated by a non Amphetamine alternative called Modafinil.
