Other comments

Questionnaire determined that cataplexy was best differentiated from other types of muscle weakness when triggered by only three typical situations: "when hearing and telling a joke," "while laughing," or "when angry." Face or neck, rather than limbs, were also more specifically involved in clear-cut cataplexy.

Other items, such as length of attacks, bilaterality, and alteration in consciousness, were poorly predictive.

Patient populations in who questionnaire has been validated Patients referred to a Sleep Disorder Clinic
