Narcolepsy is basically a neurological state affecting the sleep patterns of an individual. People with this condition experience excessive daytime sleepiness.

The most unfortunate thing about this condition is that the sleep attacks are sudden and they can occur anytime during the day.

Diagnosing this condition requires a Narcolepsy test. Doctors generally carry out a physical exam of the patient and they also have a close look at the medical history of the patient for ruling out the causes of this condition.

Narcolepsy Test

There are different methods of Narcolepsy test done for diagnosing and they are as follows:

Narcolepsy Test

Epworth Sleepiness Scale Test

This is a Narcolepsy test where the patient needs to answer eight questions by making use of a scale from zero to three.

The zero scale indicates that the patient does not fall asleep while three indicates that the patient has the tendency of falling asleep. Total score is generally between 0 and 24.

PSG or Polysomnogram

PSG or Polysomnogram is sleep study and it is a test performed in the sleep lab. This is a test that electronically records and transmits certain physical actions while the patient sleeps.

These actions include breathing patterns, brain activity and muscle movement. An experienced sleep specialist analyzes the recordings.

Multiple Sleep Latency Test

This test is carried out the morning post the polysomnogram in the sleep lab. This is a test that measures the time taken by a patient to fall asleep during the daytime. The patient is asked to take five to six scheduled naps after every two hours.

Hypocretin Test

Hypocretin is brain chemical that helps in regulating REM sleep. People suffering from Narcolepsy often possess very low level of hypocretin.

The hypocretin test helps in measuring hypocretin levels in the fluid surrounding the spinal cord. Sample of spinal fluid is obtained through spinal tap or lumbar puncture.
