How is Narcolepsy Diagnosed?

Diagnosing narcolepsy involves a combination of clinical assessments, sleep studies, and detailed patient history. Initially, a healthcare professional, such as a sleep specialist, will conduct a thorough evaluation of the patient’s symptoms. The hallmark signs of narcolepsy include excessive daytime sleepiness, sudden sleep attacks, and cataplexy, which is a sudden loss of muscle tone.

To confirm the diagnosis, sleep studies are often recommended. A polysomnography (PSG) is typically the first step, where overnight monitoring of brain waves, breathing, and other vital signs occurs during sleep. Following this, a Multiple Sleep Latency Test (MSLT) may be administered. This test measures how quickly a person falls asleep during the day and how quickly they enter REM sleep, which is particularly telling for narcolepsy patients.

In addition to these tests, doctors may gather information on family history and lifestyle, as genetics can play a role in narcolepsy. Misdiagnosis can happen, as symptoms can overlap with other sleep disorders or conditions; therefore, a comprehensive approach is essential for an accurate diagnosis.
