Sleep And It 's Effects On The Brain

In the present study we sought to characterize abnormalities in sleep architecture and quality, in a cohort of patients with medically refractory versus and controlled epilepsy, versus normal healthy controls and to study the effect of sleep parameters on cognitive function in these groups. The main observations made were of significantly longer self-reported and polysomnographic TST in patients with refractory epilepsy in comparison to controlled epilepsy and healthy controls. Sleep architecture was also found to be markedly disturbed among epilepsy patients in both groups, with prolonged REM latencies, and frequent arousals and awakenings although these abnormalities were statistically similar between the groups. Our main observation is that higher total sleep time has a negative correlation with memory and executive function performance.

Coming from a teenager, sleep is a beautiful thing that when I wake up at noon it allows me to feel fully revived and ready to seize what is left of the day. The great historic, Benjamin Franklin, once said of sleep, “Early to bed, early to rise makes a man healthy, wealthy and wise.” Nobody every really needed to prove the healthy part of his saying because most people know that after sleeping the body seems to gain energy. The second part to his statement probably could use a bit of proving because whenever I try that I never see a paycheck. The last part though is the part that I am most interested in, could having a better night’s sleep really make me a more intelligent individual? I didn’t know, the question nagged at my brain for a

A recent news article on CNN, Lack of Sleep May Shrink Your Brain, cites a research study suggesting that insomnia and other reasons for sleep deprivation may reduce brain mass. Although the study was correlational, the author of the news article focuses mostly on one of the three possible relations between sleep and brain mass: lack of sleep may cause shrinking of the brain. Only at the end of article, the author mentions that shrinking of the brain may cause lack of sleep, but completely disregards the third possibility that a third variable may cause both the shrinking of the brain and lack of sleep.

Sleeping affects the brain in ways that cannot be achieved by any other method, at least naturally. Lack of sleep is consistent with “higher levels of depressed mood, fatigue, and sleepiness,” which is observable in any person, but this trend is especially more true for adolescents, because of their developing brain and increased workload. (Fuligni, 2006) Students around the age of fourteen and fifteen are transitioning from middle school into high school and are forced to interrupt their previously set daily circadian due to earlier and later school obligations as well as increased socializing, after-school studying and extracurricular activities. The student’s home life and upbringing can play a large part in their mental health and even

When people sleep their brain’s activity changes in characteristic ways over the course of one night. These sleep patterns are classified into two main kinds of sleep – rapid-eye movement or REM and non-rapid eye movement or NREM sleep. REM sleep is most often associated with dreaming and it is thought that it assists in brain development especially in the early stages

Sleep affects the body in hundreds of ways and just to name a few, it repairs tissues, cleans the body of chemicals, and replaces neurons. After closing your eyes, you enter BREM, which stands for “before rapid eye movement,” your body slows down most bodily functions such as breathing and pulse rate to preserve energy while sleeping. The most important part of sleep is REM or “rapid eye movement,” which is the part of sleep where neurons are replaced and repaired, inadvertently making dreams. REM also completely freezes your body or well shuts down the nervous system, to prevent you from walking around when dreaming. Sleep overall is an extremely important part of life as it helps the body.

In fact, people need both types of sleep because they are equally important, since they have two different jobs they perform. Not only that, but even the meaning behind NREM and REM are absolutely different. One means "nonrapid eye movement," and the other means "rapid eye movement." In Ian Oswald's' article called "Sleep" said, "NREM is where 75% of sleep takes place, and the other 25% is REM," and "sleep does not reflect an inactive brain." Last but not lease, the sleep cycle only lasts for 90 minutes before it restarts all over again.

The chemical blockage is how you’re able to dream about doing things, but you don’t actually move and act it out in your sleep. There are disorders, however, that cause people to sleep differently than what is deemed “normal.” Such a thing would be atopia, where people act out their dreams while sleeping (Stevens, 2011). They can also sleepwalk or wake up from sleeping but not be able to move although your conscious but their body is not yet ready to move.

During a single night of sleep, a healthy adult goes through multiple different stages which repeat themselves irregularly. Therefore, sleep involves REM (rapid eye movement) sleep and nREM (non rapid eye movement) sleep, which subdivides in stages 1, 2, 3 and 4.

NREM (non-rapid eye movement) sleep is the light and deep stages of sleep “initiated by withdrawal of neurotransmitters from the reticular formation and by the inhibition of arousal mechanisms in the cerebral cortex.” The reticular formation found in the brainstem is primarily responsible for generating REM sleep, and NREM sleep is produced by projections from the reticular formation and other areas of the mesencephalon (midbrain). Normal sleep happens in cycles of NREM and REM sleep. When a person falls asleep, he first enters into a light sleep and then progresses into increasingly deeper stages of sleep (NREM cycle) for about 90 mins, followed by the initial stage of REM sleep, the two cycles alternating throughout the night. For people suffering from narcolepsy, sleep begins immediately with REM sleep and portions of REM happens involuntarily throughout the waking hours. As mentioned earlier, REM sleep is when muscles are paralyzed and when dreams take place, explains the associated symptoms of cataplexy, paralysis and hallucinations (McCance & Huether, 2014; "National Sleep Foundation,"

Sleep is necessary for basic health and survival. It plays a large role in an individual’s mental, emotional, and physiological welfare and functioning. After years of sleep research focusing on sleep-wake cycles, evidence points to the conclusion that sleep deprivation has detrimental consequences, not only on rodents, but humans as well (Cheng et al., 2015). In the past century, the average amount of time that adults sleep has decreased significantly. Consequently, sleep problems have become an epidemic, taking their toll on the health of adult populations in numerous ways. The National Sleep Foundation (NSF) conducted a Gallup Poll in March 2002 in which American lifestyles, sleep habits, and sleep problems were surveyed. The results

NREM sleep accounts for 75-80% of sleep time. Stage one makes up 3-8 % of sleep time and mostly occurs in transition from alertness to the other stages of sleep. Stage two begins approximately 10-12 minutes of stage one and compromises 45-55%

Melatonin is what keeps you going, what makes you active. Whenever you do not get enough sleep, melatonin stops being produced. As a result, your brain works harder to keep you awake and energetic like you are when you get enough sleep. According to guardianliv.com reduced serum levels have been linked to an endless list of illnesses including, cancers, memory loss, dementia, and many more. Men and Women who are not getting enough sleep need to understand that this is real, and it is even life-threatening. That does not mean that if you sleep enough every night you will never get sick, it means not getting enough sleep increases your chances of getting a disease that I have mentioned before. Sleep loss not only effects the amount of

Did you know that sleeping is how your body and mind rests, and restores its energy levels? It is an active state that affects both your physical and mental health. Every night, everyone goes through what is called a sleep cycle. You may be wondering what exactly this is. During the sleep cycle, we go through 5 stages. Theses stages are 1,2,3,4, and REM (rapid eye movement). This means that when you are sleeping, your eyes move in all different directions very quickly, and it happens 90 minutes after you fall asleep. A complete sleep cycle lasts about 90 to 110 minutes. In stages one, two, and three you are in what is called non- REM. It is a very light sleep and you can be woken up within 5-15 minutes. Then stages, four, and REM are the deep stages of sleep. Over the course of a typical night, we cycle through the stages of sleep about five times. You may not be aware, but sleep affects both infants and adults very differently.

We have always wondered whether the amount of sleep a person gets effects the brain but never found an exact answer. According to Harvard health publications people who are persistently sleep deprived are more likely to have high blood pressure, diabetes and narrowed vessels. Harvard health Publications has found that this causes us to decrease blood flow inside the brain which can cause the brain to have difficulties working properly. We can get more sleep by managing the amount of time we use for each activity we are involved in. Since I am a teenager I know it can be difficult for teenagers our age to get enough sleep because of school, after school activities and homework. According to the website healthy sleep lack of adequate sleep affect
