| | Narcolepsy |
 | | Many patients with narcolepsy experience periodic limb movement disorder, also called PLMD (formerly known as nocturnal myoclonus), in which the leg muscles involuntarily contract every 20 to 40 seconds during sleep, occasionally arousing the patient, who, however, is usually unaware of the cause of the interruption. |
 | | Narcolepsy patients with this genetic type tend to have a specific syndrome of symptoms that include cataplexy and periodic limb movement disorder. |
 | | Certainly, patients with narcolepsy have emotional difficulties because of the condition and it is often difficult, particularly for a nonspecialist, to detect the physical problem. |
