Journal Title: Online Journal of Neurology and Brain Disorders - Year 2018, Vol 1, Issue 3
Abstract
Sleep is defined as a natural decrease in the perception [1] of the external environment that occurs periodically and reversibly, but retaining a certain degree of reactivity towards the environment and autonomous functions [2]. Sleep is considered an active process of biological, cyclical and, it is essential for survival. Most adults require an amount of sleep between 7-8 hours per day; however, there are individual variations regarding the schedule, duration, and internal structure of the dream [3]. Sleep is associated with the state of physical and mental health. It is documented that during this process of neurobiological nature, functions inherent to the organism are verified [3]. Through sleep, the organism recovers from everyday fatigue [4]. Likewise; sleep plays a relevant role in the consolidation of learning and memory. On the contrary, sleep deprivation impairs psychomotor and cognitive functions including the time of reaction to a stimulus, surveillance capacity, judgment, attention and, information processing. In addition, sleep deprivation is associated with decreased concentration and high frequency of affective disorders [5-7]. It is estimated that sleep disorders and alterations in the circadian rhythm affect 15-20% of adult individuals [7,8].
