The sleep disorder is described as a medical disorder associated with sleep pattern. There are different forms of sleep disorder which include insomnia, narcolepsy, sleep apnea and cataplexy. The issues related to sleep disorder have been in existence within multiple cultures and societies since a long period of time. Moreover, due to the lack of appropriate treatment and awareness, sleeping disorder during the middle age period often considered as some sort of demonic possession for the people. It gradually resulted in deteriorating the health conditions of the victimized individuals.
