When people feel excessive sleepiness during the day or abnormally time spending in sleeping and have face trouble staying awake, in medical term, its called hypersomnia or hypersomnolence, it is a kind of neurological disorder of excessive spending time in sleep or excessive sleepiness.
People who have hypersomnia can become sleeping at any measure for example, at work or while they are drift. They may also face some other sleep-related problem like lack of energy, the inconvenience of thinking clearly.
As per research of National Sleep Foundation, near about in 40% people, some hypersomnia symptoms appear from time to time during the whole leaving period.
Excessive daytime sleepiness a kind of neurological disorder called Hypersomnia.
Learn about hypersomnia cause, symptoms, diagnosis & treatments.
Hypersomnia Symptoms :
In people with hypersomnia, excessive sleepiness is not due to another underlying medical disorder or medication. The central syndrome of hypersomnia is excessive daytime sleepiness (EDS), or elongated nighttime sleep, which has occurred for at least three months before diagnosis. Other symptoms include:
- Falling drowsy maximum times of the day.
- Taking sleep for fighting with the drowsiness but failed to achieve refreshed.
- Spend time for sleeping beyond 8 hours but not feeling relaxed.
- Having difficulty awakening up from sleep
- Feeling confused or fighting while trying to wake up
Hypersomnia Diagnosis :
The medical practitioner used various methods for quantifying the severity of daytime sleepiness by a subjective scale such as the Epworth Sleepiness Scale (ESS), invented by Dr. Murray Johns of Epworth Hospital in Australia.
ESS is a scale aimed to measure daytime sleepiness, and dignified by using a very short questionnaire. The range of the level helps proper diagnosing of sleep disorders.
Another is an objective test such as the multiple sleep latency test (MSLT). It is a sleep disorder diagnostic tool. It is used to measure the length of time from the start of a daytime doze period to the first signs of asleep, called sleep latency.
Hypersomnia can be primary, i.e., brain origin or it can be secondary to any legionary medical conditions.
Primary Hypersomnia :
Primary hypersomnia may be associated with various genetic disorders such as
Prader-Willi syndrome (PWS) – It is a genetic disorder on account of function loss of specific genes that affect many parts of the body. In newborn babies, some symptoms found like weak muscles, poor feeding, and delayed development. Beginning in childhood, people become continuously hungry, as a result, they suffer from chronic overeating (hyperphagia), obesity and type-2 diabetic.
Norrie disease – It is a genetic disorder, mainly affected on eyes and leads to blindness. Also, some individual with Norrie disease suffer from progressive hair loss, and some may have difficulties in learning.
Niemann–Pick disease – It affects lipid metabolism in the body, due to abnormal lipids metabolism causes developed and spread harmful lipids in various organs. As a result, it directly attacks the liver, spleen, brain and bone marrow.
However, hypersomnia in these set of symptoms may also be related to other secondary causes, so it is essential to complete a full medical examination and evaluation.
Secondary Hypersomnia :
Secondary hypersomnias are immensely numerous and can be secondary to disorders like clinical depression, multiple sclerosis, encephalitis, obesity. It may also be a sleep disorder like sleep apnea. It may happen due to the opposite effect of consuming specific medications, or removal from some drugs or misuse of drug or alcohol. Sleep apnea is the second most common cause of secondary hypersomnia, affecting up to 4% of middle-aged adults, generally men.
Sleep movement disorders like restless legs syndrome (RLS) and periodic limb movement disorder (PLMD) also can cause secondary hypersomnia. However, PLS does commonly reason excessive daytime sleepiness, but PLMD does not. There is not found any evidence that PLMD plays a role in the root cause of daytime sleepiness. Research showed that no interrelation between PLMD and excessive daytime sleepiness.
Hypothyroidism and iron deficiency (anemia) can also reason for secondary hypersomnia. Besides, a mood disorder such as depression, anxiety, and bipolar disorder may also be connected with hypersomnias.
Treatments of Hypersomnia :
There are several treatments confirmed by Food and Drug Administration (FDA) such as stimulant medications, non-stimulants medication and sodium oxybate which may retrieve patients quality of life, depending on the real cause or reason for hypersomnia that is diagnosed.
