What Is Cataplexy in Narcolepsy?

Most people living with narcolepsy have cataplexy, but it is not always obvious.

Nearly two-thirds of people living with narcolepsy have cataplexy, which is called type 1 narcolepsy. Cataplexy is the sudden and brief loss of muscle strength or muscle tone often brought on by strong emotions or certain situations, like laughing or being startled. People living with narcolepsy who do not experience cataplexy have what is called type 2 narcolepsy.

Cataplexy can be brought on by different emotions or situations.

  • Excitement – Gina & Ijeoma
  • Being the center of attention – Sean & Sharon
  • Laughter – Andre
  • Feeling anxious – Sharon
  • Anticipation – Sean
