DSM-5 Narcolepsy Criteria

Yes, narcolepsy is recognized as a Diagnostic and Statistical Manual of Mental Disorders (DSM-5) diagnosis under the category of sleep-wake disorders.

Narcolepsy consists of four classic symptoms, although not all patients experience all four: excessive daytime sleepiness (EDS), cataplexy, sleep paralysis, and hypnagogic hallucinations. Patients with narcolepsy frequently experience disturbed nocturnal sleep, meaning their nighttime sleep is often fragmented and interrupted by multiple awakenings.

Yes, narcolepsy can co-exist with other sleep-related conditions, such as obstructive sleep apnea (OSA), restless legs syndrome (RLS), and periodic limb movement disorder (PLMD). It can also be comorbid with psychiatric disorders, such as depression or anxiety.
