Cataplexy
The graph below summarises the duration of attacks of cataplexy in a group of sujects with narcolepsy.
(Adapted from Narcolepsy Eds: Guilleminault C et al, New York:Spectrum Publications, 1976)
As can be seen from the graph above most attacks of cataplexy are transient, being terminated within one minute. However in some instances they can persist for up to 20 minutes. In very rare cases the individual may suffer from prolonged cataplexy - a condition known as status cataplecticus.
