Narcolepsy

Common Vignette: 19 year old male presents with symptoms of sleepiness for over 3 months. When telling a joke or surprised, his jaw becomes slack, but consciousness is maintained. A few times he has had to hold on to the wall or railing for support. These episodes last between 30 seconds to 2 minutes. Also when waking up from sleep, he occasionally feels paralyzed, unable to move. This is very frightening to him, but resolves spontaneously. Because of sleepiness, his school performance has deteriorated.

Narcolepsy Summary EDS / Cataplexy / Sleep Hallucinations Etiology unclear but genetics / environment / autoimmune possible Treat both EDS and Cataplexy

Prevalence 0. 05% general population (1 out of 2, 000) 55% of narcoleptics are ever diagnosed (some sources 1 out of 4) 10 years is the time to diagnosis 2 nd decade of life is peak onset Symptoms are rare before 5 years of age EDS before cataplexy Japan 0. 16% Israel <0. 01%

Signs and Symptoms EDS (excessive day time sleepiness) Cataplexy Sleep Paralysis Sleep Hallucinations

Signs and Symptoms EDS Can also occur while active Can occur as a sleep attack Can occur several times a day Naps are refreshing (important to distinguish from idiopathic hypersomnia) Can result in poor work / school performance Need to monitor driving safety

Signs and Symptoms Cataplexy (60% of patients with narcolepsy have it) Abrupt / reversible loss of voluntary muscle tone Tendon reflexes inhibited 30 seconds – 2 minutes Usually bilateral Consciousness usually maintained Severity and frequency vary Common= muscle tone decreases, slurred speech Severe= total body collapse Important to identify triggers

Signs and Symptoms Sleep Paralysis Upon awakening or falling asleep Frightening to patient (affects 3 -5% of non-narcoleptic population as well)
