Features of cataplexy are as follows:

  • If severe and generalized, cataplexy may cause a fall

  • More subtle forms exist with only partial loss of tone (eg, head nod, speech alteration, and knee buckling)

  • Respiratory and extraocular movements are preserved

  • Cataplexy is usually triggered by emotions (especially laughter and anger)
