Does Lack Of Sleep Affect Brain Function

Why I Can’t Sleep : Causes Of Sleep Deprivation | Dr. J9 Live

Sleep deprivation does affect brain function. The brain has a prime opportunity to regenerate and revitalise itself through slumber. If you are sleep deprived, your brain feels the effects through exhaustion and it not being able to carry out its functions.

Neurons actively communicate with each other during sleep, playing a housekeeping function. Toxins built up from the day are removed while the signals become muddled up either delaying your reflexes and coordination.

Can Sleep Deprivation Cause Memory Problems

Over time, going without proper sleep will cause memory problems. Your short-term and long-term memory and ability to form new memories can be impeded by a lack of sleep.

According to studies from the Universities of Groningen and Pennsylvania, sleep deprivation leads to a change in neurons as they struggle to connect. After 5 hours of sleep deprivation, the neurons begin to tire and wear out.

Researchers also found that by catching up on sleep or settling your sleep debt, you can restore your brains functioning and overall memory function.

Reaching Out For Support

While mild anxiety symptoms might lift on their own, persistent anxiety generally wont improve without support from a trained mental health professional.

To find therapists in your area who specialize in anxiety, consult a therapist directory or try a quick Google search.

Interested in giving online therapy a try? Start with our recommendations for the top online therapy services.

Let your therapist know about all of your symptoms, not just memory loss. Make sure to let them know if memory problems dont improve with treatment.

Already receiving some kind of treatment for anxiety and still have symptoms? Its worth talking to a professional about other approaches.

Not all treatments work for everyone, and it may take time to find the most effective approach for you.

Some people benefit from therapy alone, while others find a combination of medication and therapy most effective.

Mayo Clinic Q And A: Impaired Sleep And Risk Of Dementia

DEAR MAYO CLINIC: Is it true that sleep deprivation eventually could lead to Alzheimers disease?

ANSWER: There have been a number of studies looking at the effect of sleep on disorders that impair cognitive function, such as Alzheimers disease. Although no research has shown a clear link between sleep deprivation and Alzheimers, it is possible that impaired sleep over many years may put you at higher risk for some forms of dementia, including Alzheimers disease.

Alzheimers disease is a progressive type of dementia that impairs memory, thinking and social abilities severely enough to interfere with daily functioning. Sleep problems are a common component of Alzheimers disease. Alzheimers disease can disrupt the normal sleep-wake cycle, causing daytime drowsiness and nighttime restlessness. And, as Alzheimers gets worse over time, these sleep disturbances often get worse, too. For many people with the disease, round-the-clock naps eventually replace deep, restorative nighttime sleep.

The question of whether a lack of healthy sleep could contribute to the development of Alzheimers disease is under investigation. Although the exact cause of Alzheimers isnt well-understood, researchers believe that a buildup of an abnormal protein called beta-amyloid in the brain contributes to the disease. As it accumulates in the brain, beta-amyloid appears to damage or destroy brain cells by interfering with communication among cells.

Common Causes Of Forgetfulness

6 Tips to Combat the Effects of Sleep Deprivation

Memory slips are aggravating, frustrating, and sometimes worrisome. When they happen more than they should, they can trigger fears of looming dementia or Alzheimers disease. But there are some treatable causes of forgetfulness. Here are six common ones.

Lack of sleep. Not getting enough sleep is perhaps the greatest unappreciated cause of forgetfulness. Too little restful sleep can also lead to mood changes and anxiety, which in turn contribute to problems with memory.

Medications. Tranquilizers, antidepressants, some blood pressure drugs, and other medications can affect memory, usually by causing sedation or confusion. That can make it difficult to pay close attention to new things. Talk to your doctor or pharmacist if you suspect that a new medication is taking the edge off your memory. As shown in the table below, alternatives are usually available.

Medications that may affect memory and possible substitutes

If you take these drugs

ask about switching to one of these drugs


another antidepressant such as fluoxetine or sertraline , or a different type of antidepressant such as duloxetine or venlafaxine


Underactive thyroid. A faltering thyroid can affect memory . A simple blood test can tell if your thyroid is doing its job properly.

Sleep Deprivation Causes Memory Loss

Weve written extensively about How Sleep Deprivation is a Brain Drain.

Studies from the University of California, Berkeley showed that poor sleep could cause memory loss, forgetfulness, and brain deterioration, especially in older adults.

Certain brain waves help store memories and are responsible for transferring memories to the prefrontal cortex where long term memories are stored. The brain waves are produced during sleep, and if the memories never reach the prefrontal cortex, the long term memories are never formed which leads to forgetfulness.

Memory isnt the only casualty of sleep deprivation. If you want to know what happens to your brain when youre sleep deprived, check out our recent article which includes a list of side effects of short term sleep deprivation.

When To See A Doctor For Memory Loss

Its time to consult a doctor when memory lapses become frequent enough or sufficiently noticeable to concern you or a family member. If you get to that point, make an appointment as soon as possible to talk with your primary physician and have a thorough physical examination. Even if youre not displaying all the necessary symptoms to indicate dementia, now may be a good time to take steps to prevent a small problem becoming a larger one.

Your doctor can assess your personal risk factors, evaluate your symptoms, eliminate reversible causes of memory loss, and help you obtain appropriate care. Early diagnosis can treat reversible causes of memory loss, lessen decline in vascular dementia, or improve the quality of life in Alzheimers or other types of dementia.

What Happens When You Sleep

Scientists don’t know exactly how sleep enhances memory, but it appears to involve the brain’s hippocampus and neocortex — the part of the brain where long-term memories are stored. It is thought that during sleep, the hippocampus replays the events of the day for the neocortex, where it reviews and processes memories, helping them to last for the long term.

Researchers continue to investigate the stages of sleep involved in making certain types of memories. Some studies have shown that certain kinds of memories become stable during rapid eye movement sleep — the time when you dream. Other studies have found that some types of memories are most often secured during slow-wave, deep sleep. Scientists are getting closer to understanding what sleep does to our brain, but there are still many questions to be answered.

Whatâs certain is that sleep is a biological necessity — we need it to survive. Unfortunately, in this day and age, few of us are able to get the sleep we need to function our best. Experts recommend adults get seven to nine hours of sleep each night. Although this may not be attainable every night, it should be the goal.

Will Improving Sleep Benefit Cognition

Sleep Deprivation, Can This Cause Depression?

For people with sleeping problems, improving sleep offers a practical way to enhance their cognitive performance. Getting the recommended amount of uninterrupted sleep can help the brain recuperate and avoid many of the negative consequences of poor sleep on diverse aspects of thinking.

Researchers and public health experts are increasingly viewing good sleep as a potential form of prevention of dementia and Alzheimers disease. Although more studies are needed to conclusively determine sleeps role in preventing cognitive decline, early research hints that taking steps to improve sleep may reduce the longer-term likelihood of developing Alzheimers dementia.

Sleep Loss Impairs Judgment Especially About Sleep

Lack of sleep can affect our interpretation of events. This hurts our ability to make sound judgments because we may not assess situations accurately and act on them wisely.

Sleep-deprived people seem to be especially prone to poor judgment when it comes to assessing what lack of sleep is doing to them. In our increasingly fast-paced world, functioning on less sleep has become a kind of badge of honor. But sleep specialists say if you think youââ¬â¢re doing fine on less sleep, youââ¬â¢re probably wrong. And if you work in a profession where itââ¬â¢s important to be able to judge your level of functioning, this can be a big problem.

ââ¬ÅStudies show that over time, people who are getting six hours of sleep, instead of seven or eight, begin to feel that theyââ¬â¢ve adapted to that sleep deprivation — theyââ¬â¢ve gotten used to it,ââ¬ï¿½ Gehrman says. ââ¬ÅBut if you look at how they actually do on tests of mental alertness and performance, they continue to go downhill. So thereââ¬â¢s a point in sleep deprivation when we lose touch with how impaired we are.ââ¬ï¿½

What Were The Results Of The Study

The researchers say that sleep deprivation had several effects on cellular measures of memory in the mouse hippocampus. In particular, they noted reduced cAMP signalling and an increase in the activity and concentration of the enzyme phosphodiesterase 4 .

Treatment of mice with a phosphodiesterase inhibitor reversed the reduction in the activity of cAMP molecules that was brought on by sleep deprivation.

Melatonin And Cortisol Two Hormones That Affect Your Sleep

Your sleep patterns are regulated by two main hormones cortisol and melatonin.

Together, melatonin and cortisol, help support the bodys natural circadian rhythm which consists of a sleep-wake cycle most often synchronized with 24-hour daytime/nighttime period.

Cortisol levels increase peak in the morning, raising blood pressure and blood sugar, jump starting and preparing your body for the day ahead. Levels decline naturally throughout the day and drop to their lowest point around midnight.

Melatonin, also known as the sleep hormone, increases as external light diminishes and creates drowsiness. During the night, melatonin levels decrease while simultaneously cortisol levels increase to help suppress melatonin in the morning and prepare the body to wake.

If the balance is disrupted, and cortisol levels remain high closer to bedtime, it can lower levels of melatonin which help prepare the body for sleep. This can lead to a delayed onset of sleep.

The Relationship Between Dementia And Sleep

Sleep and dementia is a complicated topic. Different types of dementia are associated with different sleep problems. Researchers are also not yet sure which way the interaction goes – whether poor sleep causes or exacerbates dementia or if dementia leads to poor sleep. Some researchers believe that both of these theories could be true, and the relationship could be circular.

On top of this, it is unclear what the mechanisms are that underlie these interactions.

It is clear that more research is needed to understand this relationship in particular research that observes large groups of affected people for very long periods of time.

Sleep Deprivation And Junk Food Cravings

The inability to sleep may lead most of us to open the fridge at 2 a.m. and reach out for the unhealthiest, high-calorie snacks, but why? A study in the journal Nature Communications found sleep deprivation disrupts food choices in two ways: First, it dampens activity in several brain areas responsible for appetitive evaluation our ability to rank different foods in the mind based on what they want, and second, an increase in the brains amygdala responsible for controlling the salience of food. Excessive sleepiness impairs decision-making abilities while increasing our desire for unhealthy foods. This affirms the association between a lack of sleep and an increase in weight gain and obesity.

Alcohol Or Illicit Drugs

Drinking alcohol or using illicit drugs can impair your memory, both in the short term and long term. From blackouts to an increased risk of dementia years later, these substances can significantly harm your memory, among many other things. Too much alcohol can also cause Wernicke-Korsakoff syndrome, which if treated immediately, may be able to be partially reversed in some people.

Relaxation Music For Sleep Stress And Anxiety Relief

How Can Sleep Deprivation Affect You?

Music therapy uses sound and rhythm to reduce stress and increase anxiety relief. For people who have problems with sleeping and sleep apnea stress, listening to relaxation music for sleep stress and anxiety relief is helpful.

Relaxation music for sleep stress and anxiety relief stimulates the limbic system. This is the central station in the brain for our feelings. People listening to classical music did recreate the structure and meaning of the music in their limbic systems. At the same time, the limbic regions release dopamine when listening to music, which is known as the happiness hormone.

Relaxing music is what makes us feel at home before sleeping. We can also affect our well being with the help of the right environment. We have a way to create the perfect home environment for sleep through music.

Mediation music for meditation practice may also help you reduce stress and fall asleep. It can serve to neutralize external disturbing sound sources. It can also help to let go of thoughts and worries while concentrating on the sounds during your meditation sessions before bedtime.

Memory Loss Cause # 8 Diabetes

Researches reveal that among individuals aged 65 and also older, 26% have identified or undiagnosed diabetes mellitus, and one in five are prescribed a medicine to deal with diabetic issues, creating an additional set of possible concerns for cognition. Victims of diabetics issues are already familiar with the results of hypo- or hyper-glycemia on memory as well as overall state of mind, and also it is clinically confirmed that diabetes has a tendency to have dramatic impacts on cognition..

If you presume diabetes may be the perpetrator of your recent memory issues, please connect to your medical professional for a check-up. They can conveniently as well as promptly check your blood glucose levels with a fast finger prick, and carry out more examinations if it promises that diabetic issues is the trouble. The doctor will be able to suggest insulin and other medicine if you need them, but there are still a few points suggested by the American Diabetes Association that youll need to do at home, and also need to begin prior to you are detected as diabetic person:.

Eat right- it could be apparent to stay clear of excessive sugar, however did you recognize that basic diet plan changes such as minimizing gluten consumption and also increasing healthy and balanced fats can naturally maintain your blood glucose regulated?Drink plenty of water.Rest well.Exercise 150 minutes a week, and take night walks to keep your blood glucose low throughout the evening.

What Kind Of Scientific Study Was This

This was a laboratory animal study, in which the researchers identified molecular mechanisms that may cause brief sleep deprivation to alter brain function.

The researchers discuss the importance of the topic, saying that millions of people regularly have insufficient sleep. Past research on animal learning has shown that a major effect of sleep deprivation is memory deficiency in a part of the brain called the hippocampus. The hippocampus is a special area of densely packed nerves located deep within the brain. It forms part of the limbic system, which plays a major role in long-term memory and spatial navigation.

Over five hours, two groups of mice were either allowed to rest or were constantly disturbed by being handled. Each group then had their hippocampus response to electrical stimulation examined using a method called long-term potentiation. This technique has been used in previous neuroscience experiments to measure the cellular responses behind learning and memory.

Researchers then assessed the levels of a phosphodiesterase enzyme called PDE4, one of five PDE enzymes involved in chemical reactions with a molecule called cAMP. The body uses cAMP as a cell messenger, triggering processes initiated by other chemicals that cannot pass through cell membranes.

Sleepiness Makes You Forgetful

Trying to keep your memory sharp? Try getting plenty of sleep.

In 2009, American and French researchers determined that brain events called ââ¬Åsharp wave ripplesââ¬ï¿½ are responsible for consolidating memory. The ripples also transfer learned information from the hippocampus to the neocortex of the brain, where long-term memories are stored. Sharp wave ripples occur mostly during the deepest levels of sleep.

Sleep Deprivation And Memory Loss

Chronic Anxiety, Stress and Memory Loss

On the days that youre most tired, you may also find that youre most forgetful and unfocused. Sleep helps us refine how we store memory, but a lack of sleep can lead to permanent cognitive issues, such as memory loss. According to a University of California, Berkeley, study in the journal Nature Neuroscience, researchers found memories may be getting stuck in the hippocampus the part of brain involved in memory forming, organizing, and storing due to the poor quality of deep slow wave sleep, which is then overwritten by new memories. In addition, sleep deprivation can cause brain deterioration, which may help explain memory loss in the elderly.
