Research has also focused on sleep and its role in procedural memory —the remembering "how" to do something for example, riding a bicycle or playing the piano. REM sleep seems to plays a critical role in the consolidation of procedural memory.

Other aspects of sleep also play a role: motor learning seems to depend on the amount of lighter stages of sleep, while certain types of visual learning seem to depend on the amount and timing of both deep, slow-wave sleep SWS and REM sleep. Another area that researchers study is the impact that a lack of adequate sleep has on learning and memory.

When we are sleep deprived, our focus, attention, and vigilance drift, making it more difficult to receive information. Without adequate sleep and rest, over-worked neurons can no longer function to coordinate information properly, and we lose our ability to access previously learned information.

In addition, our interpretation of events may be affected. We lose our ability to make sound decisions because we can no longer accurately assess the situation, plan accordingly, and choose the correct behavior. Judgment becomes impaired. Being chronically tired to the point of fatigue or exhaustion means that we are less likely to perform well. Lapses in focus from sleep deprivation can even result in accidents or injury. For more information about how sleep deprivation affects performance, see Sleep, Performance, and Public Safety.

Low-quality sleep and sleep deprivation also negatively impact mood, which has consequences for learning. Alterations in mood affect our ability to acquire new information and subsequently to remember that information. Although current research suggests that sleep is essential for proper memory function, there are unanswered questions, as in any area of active scientific inquiry.

For example, certain medications will significantly, if not entirely, suppress REM sleep. Studies of the selective impact of sleep on types of thinking do not always generate consistent results.

This may be the result of differences in the people in the studies, how their sleep is changed in the research, or how cognitive effects are measured. Nevertheless, there are some general findings about ways that poor sleep may impair intellectual performance. There are strong indications that sleep and memory are closely linked. Lack of sleep hinders working memory, which is necessary to remember things for immediate use.

Both NREM and REM sleep appear to be important for broader memory consolidation , which helps reinforce information in the brain so that it can be recalled when needed. For example, NREM sleep has been linked with formation of declarative memory, which includes things like basic facts or statistics, and REM sleep is believed to boost procedural memory such as remembering a sequence of steps. Poor sleep impairs memory consolidation by throwing off the normal process that draws on both NREM and REM sleep for building and retaining memories.

Studies have even found that people who are sleep deprived are at risk of forming false memories. Fragmented sleep has also been found to negatively affect memory even if a person gets plenty of total hours of sleep.

On top of the consequences for memory, poor sleep detracts from other cognitive tasks. It diminishes placekeeping , which includes the ability to carry out instructions. Motor skills, keeping rhythm, and even some types of speech are worsened without proper sleep.

Some studies have found lack of sleep to hinder cognitive flexibility , reducing the ability to adapt and thrive in uncertain or changing circumstances. Another way that poor sleep impairs thinking is by altering how emotional information is understood.

When learning something new, analyzing a problem, or making a decision, recognizing the emotional context is often important. However, insufficient sleep — which frequently affects mood — impedes the ability to properly process this emotional component of information.

In many cases, this disrupted emotional response impairs judgment. This can become negatively reinforcing because a lack of sleep limits our ability to learn from these mistakes since the normal method of processing and consolidating emotional memory is compromised. Creativity is another aspect of cognition that is harmed by sleeping problems.

Connecting loosely associated ideas is a hallmark of creativity, and this ability is strengthened by good sleep. NREM sleep provides an opportunity for information to be restructured and reorganized in the brain, while new ideas and links between thoughts often emerge during REM sleep. These processes enable insight, a core element of innovation and creative problem-solving. Limited or restless sleep can also indirectly affect cognition because of other problems that they cause.

Sleep deprivation may worsen symptoms of mental health conditions like anxiety and depression. The existing research strongly supports the notion that poor sleep detracts from effective thinking.

Without quality sleep, people are more likely to make errors, fail to take in new information, suffer deficits in memory, or have impaired decision-making. As a result, poor sleep can harm intellectual performance, academic achievement, creative pursuits, and productivity at work.

The cognitive impacts of poor sleep can also create health risks, including life-threatening dangers from drowsy driving or operating heavy machinery without adequate sleep. The most obvious cognitive effects of poor sleep can be felt immediately, but mounting evidence shows that sleep influences the long-term risks of cognitive decline and dementia. Research shows that sleep helps the brain conduct important housekeeping, such as clearing out potentially dangerous substances like beta amyloid proteins.

Studies have found that even one night of sleep deprivation can increase the amount of beta amyloid in the brain. This is one possible explanation for why insufficient sleep and sleep fragmentation have been associated with cognitive decline and dementia. Furthermore, in people already diagnosed with dementia, poor sleep has been linked to a worse disease prognosis.

Not everyone is affected by poor sleep in the same way. Studies have found that some individuals may be more inclined to have cognitive impairment from sleep deprivation, and this may even have a genetic component.

Research has generally discovered that adults are better at overcoming the effects of sleep deprivation than younger people. Teens are considered to be especially high-risk for detrimental effects of poor sleep on thinking, decision-making, and academic performance because of the ongoing brain development occurring during that age.

Some studies have also found that women are more adept at coping with the effects of sleep deprivation than men, although it is not yet clear if this is related to biological factors, social and cultural influences, or a combination of both.

Sleep disorders frequently involve insufficient or fragmented sleep, so it comes as little surprise that they can be linked to cognitive impairment. Insomnia, which can involve problems with both falling asleep and staying asleep through the night, has been connected to both short- and long-term cognitive problems. Obstructive sleep apnea OSA is another one of the most common sleep disorders. It occurs when the airway gets blocked, which then leads to lapses in breathing during sleep and reduced oxygen in the blood.

OSA has been linked with daytime sleepiness as well as notable cognitive problems related to attention, thinking, memory, and communication. Studies have also found that people with sleep apnea have a higher risk of developing dementia. In many cases, research has discovered that both too little and too much sleep are associated with cognitive decline. The explanation for this association remains unclear.

It is not known if excess sleep is caused by a coexisting health condition that may also predispose someone to cognitive problems. Overall, these research findings are an important reminder that recommendations for healthy sleep involve both a minimum and a maximum.

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. Anyone who feels that they are experiencing cognitive impairment or excessive daytime sleepiness that affects their thinking should talk with their doctor as a first step.

A doctor can help identify or rule out any other conditions, including sleep disorders, that may be causing these symptoms.
