All people suffering from narcolepsy experience excessive daytime sleepiness. The exact cause of this disease is not known yet but researchers believe that narcolepsy is the result of the low levels of the brain chemical, hypocretin. The part of the brain that controls falling asleep do not function properly and might make you fall asleep without any warning during the daytime when an individual should be awake and active.
The onset of the symptoms of narcolepsy can be gradual or sudden. Excessive daytime sleepiness is the first symptom of narcolepsy and later it is accompanied by other symptoms such as sudden muscle weakness, hallucination, sleep paralysis and sleep disruption.
Hypothyroidism is defined as an underactivity of the thyroid gland and it is a condition in which the thyroid gland in the body is unable to produce enough thyroid hormone and results in the slowing down of the body processes. The thyroid gland is an endocrine gland that is located in the lower front of the neck and is responsible for making thyroid hormones. It primarily makes two hormones – thyroxine (T4) and triiodothyronine (T3). Thyroid hormones are important for various body functions such as metabolism and are somewhere responsible for normal functioning of various body organs.
Hypothyroidism is associated with many symptoms and some of the classic symptoms of hypothyroidism include extreme tiredness, weight gain, cold intolerance, constipation, and dry skin and hair. With hypothyroidism, alterations in sleeping habits are very common such as excessive daytime sleepiness and prolonged nighttime sleep.
Numerous studies suggest that most patients having symptomatic hypothyroidism also suffer from obstructive sleep apnea. Obstructive sleep apnea is a serious sleep disorder that disrupts the sleep as it causes breathing problems during sleep. Excessive sleepiness and extreme tiredness are the most common symptom of obstructive sleep apnea.

The brain abnormality in epilepsy can result from genetic disturbances or from structured that can be inherited or acquired. In simple terms, some of the causes of epilepsy include brain abnormality, stroke, brain tumor, infections that affect the brain, and genetic factors. Epilepsy affects an individual’s consciousness level.
Brain abnormalities are closely associated with the sleep disorders. Epilepsy causes interictal epileptic discharges and arousals from sleep. This sleep disruption is the major cause of excessive sleepiness. Excessive sleepiness is a common side effect of epilepsy. In fact, epilepsy is associated with many sleep disorders such as sleep apnea, restless leg syndrome, idiopathic hypersomnia and periodic limb movement in sleep. The occurrence of any of these sleep disorders can be the cause of excessive daytime sleepiness along with prolonged nighttime sleep.
