Sleep – Wake Disorders
Sleep-Wake disorders are divided into two major categories: Dyssomnias and Parasomnias.
Dyssomnias involve difficulties in getting enough sleep, problems with sleeping when you want to, and complaints about the quality of sleep, such as not feeling refreshed even though you have slept the whole night. Parasomnias are characterized by abnormal behavioral or psychological events that occur during sleep, such as nightmares and Sleepwalking.
About Hypersomnolence Disorder:
Hypersomnolence disorder involve sleeping too much. Many people who sleep all night find themselves falling asleep several times the next day.
1. Recurrent periods of sleep or lapses into sleep within the same day.
2. A prolonged main sleep episode of more than an hour per day that is non-restorative.
3. Difficulty being fully awake after abrupt awakening.
4. Occurs at least 3 times per week for at least 3 months.
A little research on the causes of Hypersomnolence has been done. Genetic influences seem to be involved in a portion of cases, with individuals having an increased likelihood of having certain genetic factors. A significant subgroup of people diagnosed with hypersomnolence disorder previously were exposed to viral infection such as mononucleosis, hepatitis and viral pneumonia, which suggests there may be more than one cause. Excess serotonin might also be one of the causes.
The Suggested treatment for Hypersomnolence is usually medical which includes stimulant drugs.
