Narcolepsy ICD 10, Diagnosis and Treatment

Posted on 171 views

Narcolepsy ICD 10 makes it easier to identify narcolepsy because every patient has it differently. This disease can be caused by an external factor. For this reason, identifying the cause can provide insight on how the doctor should handle it. Narcolepsy lasts a lifetime. The patient can only manage the symptoms. This disease can affect someone at any age, can develop as early as 10 years old, but the time of diagnosis varies. It’s possible that someone knows that he has his disease after having it for 10 years.

Symptoms: Narcolepsy ICD 10

Narcolepsy has a few common symptoms. Daytime sleepiness is one of them. Sufferers often say that they have trouble staying awake during the daytime. Meanwhile, some patients also have hallucinations although this doesn’t happen to every patient. Hallucinations are sensations that feel real, but haven’t actually occurred in real life.

Another common symptom is sleep paralysis. Sleep paralysis is the inability of the body to move during sleep, but at the same time the mind is aware of what’s happening. This happens because there’s a problem entering or getting out of the REM cycle.


In some cases, narcolepsy results from a low level of hypocretin-1 in the cerebrospinal fluid. It could happen because there is a problem with the way the orexin/hypocretin neurons work, particularly in the lateral hypothalamus.


Narcolepsy requires a thorough clinical examination. The doctor needs to know the family history of the patient and learn all the symptoms that he experiences. Some sufferers have cataplexy, but it doesn’t occur in all population. This is why studying the symptoms is important because they are probably related.

There is a test known as polysomnogram, which is designed for identifying narcolepsy. There is another essential test, Multiple Sleep Latency Test. Both use different parameters to identify narcolepsy in someone. PSG for instance monitors the patient’s brain wave changes, eye movements, etc.


Treatment is provided based upon the symptoms that the patient have. For example, when daytime sleepiness comes as a symptom, then medications that work as stimulants will be helpful. One of the examples is modafinil. Modafinil has been used for decades to treat daytime sleepiness in narcoleptics. This is not the only drug available for the treatment of excessive sleepiness.

There are also methamphetamine, methylphenidate, etc. Meanwhile, if cataplexy is present as a symptom, another medication will be necessary to take it under control. Xyrem is one of the drugs available for this condition. It helps control the sudden loss of muscle control that often occurs in people with narcolepsy. Due to the potentially serious side effects, it’s good to ask for your doctor’s advice before taking any drug.
