Cataplexy is muscle paralysis that comes on in sudden attacks and you are most likely to suffer from this should you suffer from Narcolepsy. The attacks can be triggered by emotions, e.g. happiness, excitement, anger etc. There are also a number of other factors that can trigger the attack, such as a heavy meal, ongoing stress and so forth. Your attacks will vary in severity and you may find that you lose control of a certain area of muscles, such as the ones in your arms, or you may lose control of all your muscles. If you do lose control of all your body muscles this can happen over several days and quite regularly, and you would then be deemed a “Status Cataplectic”. Common treatments for Cataplexy are anti-depressants and Sodium Oxybate. Your doctor should be consulted on the best medicines to take for the condition.
