Clinical background

Narcolepsy is a chronic neurological disorder that disrupts the regulation of sleep and wakefulness.

The patients suffer from pronounced sleepiness during the day and disturbed sleep at night. Cataplexy, hallucinations, and sleep paralysis are also common symptoms.

Narcolepsy is classified according to the International Classification of Sleep Disorders (ICSD3) as narcolepsy type 1 (NT1) or 2 (NT2). Narcolepsy type 1 is considered an autoimmune disease where the immune system attacks and destroys the orexin-producing neurons in the hypothalamus.

The level of Orexin in cerebrospinal fluid is reduced at NT1.

Over 95% of all people with NT1 are carriers of HLA-DQB1*06:02.

Patients with NT2 lack cataplexy and have normal levels of orexin/hypocretin. The cause of type 2 is still unknown.
