Cataplexy

Cataplexy

A sudden and uncontrollable, brief loss of muscle tone (paralysis of muscles} caused by experiencing strong or intense emotions (most often laughter, though also anger, pain, fear and stress are also a trigger). Cataplexy only occurs in Type 1 narcolepsy. Cataplexy can vary from partial cataplexy, which may involve the slurring of speech to full cataplexy where an individual may experience weakness of the face, limbs, and trunk, which causes them to slump to the ground, awake but unable to talk or move.
