Dementia and sleep disturbances

Did you know that sleep is incredibly important for overall health, including memory? In fact, research has shown that lack of sleep can lead to dementia and other serious health problems. It’s important to get a good night’s sleep every night in order to keep your mind and body healthy. In this blog post, we will discuss the relationship between dementia and sleep, and how you can get a better night’s rest.

How does dementia change sleep patterns?

The sleep-wake cycle is driven by a biological and psychological process known as circadian rhythm, which response to cues in our environment. Dementia patients’ circadian rhythms are disrupted, resulting in reduced sleep quality when compared to non-demented individuals.

The suprachiasmatic nucleus (SCN) is a portion of the brain that acts as our internal clock and responds to cues such as light to tell us when we should be awake and when we should feel sleepy. Alzheimer’s disease is the most common form of dementia, and patients with this condition often have damaged cells in the SCN and decreased cellular activity in this region of their brains. Because of their failure, people with this syndrome are frequently unable to follow a 24-hour sleep-wake cycle and instead Sleep excessively during the day and sleep much less at night.

Dementia is also associated with sleep structure modifications. When we sleep, our bodies cycle through a series of sleep stages, beginning with light sleep (stages 1 and 2), followed by deep sleep (stage 3 or slow-wave sleep), and then dream sleep (also known as rapid eye movement or REM sleep).

Slow-wave sleep and rapid eye movement (REM) sleep are important parts of how sleep aids in the restoration of the body and mind. People with dementia spend less time sleeping in slow-wave and REM stages and more time at earlier points in their sleep cycles. This reduction in deep sleep and REM sleep might get worse as dementia progresses.

What sleep disorders are common in people with dementia?

Sleep problems are common among people with dementia. The following sleep disorders are most prevalent in older individuals, but they occur at even higher rates in persons with dementia.

  • Restless legs syndrome (RLS): RLS is a persistent and insatiable urge to move the legs, particularly at night. Lewy body dementia, a form of dementia, causes RLS.
  • Periodic limb movement disorder (PLMD): PLMD causes night-time limb and/or arm flailing, which is known as Restless Legs Syndrome. Many individuals who have PLMD also suffer from RLS.
  • Obstructive sleep apnea (OSA): Obstructive sleep apnea (OSA) is a breathing problem characterized by airway collapse during sleep. OSA affects 40% of people with Alzheimer’s disease. Having obstructive sleep apnea (OSA) also raises the risk of dementia.
  • REM sleep behavior disorder: Sleep terrors are sleep disorders in which people act out their dreams, especially when they are sleeping. It’s most common among people with Lewy body dementia, although it may also be the first sign of this illness.
  • Depression: Depression is a mood problem, but it is linked to sleep problems as well. Depression is prevalent among those with dementia and has been observed to get more severe as the disease progresses.

How Does Sleep Affect Dementia Risk?

According to experts, a bidirectional relationship exists between sleep and dementia. In other words, while poor sleep may raise dementia risk and symptoms, the presence or absence of dementia has an impact on one’s sleep quality as well. For example, amyloid-beta accumulation in the brain is one of the first signs of Alzheimer’s disease.

Sleep deprivation has been shown in studies on animals and a small trial in people to raise amyloid-beta levels in the brain. At the same time, patients with amyloid plaques have poorer sleep quality than Alzheimer’s disease patients without plaques, according to studies.

Sleep is also necessary for our cognitive performance and memory formation, according to research. Observational studies have shown that sleep problems are linked to cognitive deterioration and dementia. These investigations, however, do not establish a cause-and-effect link. Although further study is needed to understand how much sleep affects dementia risk, there are many tried-and-true techniques you can use to improve your sleep.

What Can Help Someone With Dementia Sleep Better?

Sleep hygiene is the most important treatment for sleep disorders in those with dementia. Sleep hygiene is a set of instructions and environmental factors that encourage good sleep. The following sleep hygiene recommendations may assist people who have dementia in improving their sleeping habits:

  • Maintain a regular schedule: Setting regular wake and sleep times might help to synchronize circadian rhythm in individuals with dementia. Before going to bed, create a relaxing evening routine that includes quiet, soothing activities. Television and other electrical devices can be stimulating and emit blue light, which causes sleep deprivation by disrupting the body’s natural internal clock.
  • Limit naps: Taking a catnap during the day may help you fall asleep faster at night, so it could be useful in discouraging napping or restricting it to only one nap that lasts less than 30 minutes.
  • Engage in physical exercise: Exercising in the hour before going to sleep can have a negative impact on sleep. However, getting exercise early in the day may help you get a better night’s sleep. It also helps promote general health and reduce daytime napping.
  • Schedule social activity: People with dementia who engaged in one to two hours of social activity a day had improved nighttime sleep, according to a study.
  • Add light exposure: Because light is a key regulator of circadian rhythm, getting natural light during the day may assist with sleep at night. Indoor bright light therapy may help if access to natural light is restricted owing to weather or other reasons.
  • Avoid stimulants: If at all feasible, avoid caffeine, alcohol, and nicotine. Furthermore, some dementia medications might disrupt sleep, so discuss this with your doctor.
  • Treat pain and sleep disorders: Treating the condition may improve sleep if a person with dementia is experiencing discomfort, suffering from a sleep problem, or exhibiting sadness. A doctor can assist you in determining which treatment options are best for you.
  • Create a calming bedroom environment: A dark, quiet, and comfortable bedroom encourage sleep. Well-loved objects near the beds of persons with dementia have been found to help some people. If complete darkness isn’t soothing, add night lights to give a feeling of security.

Some of these sleep habits may be difficult for people with dementia. It’s possible that you can’t control the amount of noise in a nursing home or assisted living facility, for example. Consider investing in a white noise machine to drown out outside noises.

A person with dementia may have trouble keeping a regular bedtime due to napping or changing daily routines, however maintaining a consistent wake time can help to maintain the circadian rhythm. A medical professional or sleep expert is in an excellent position to provide personalized sleep hygiene suggestions based on the specific circumstances.

Sleep disturbances in dementia

Dementia patients are often drowsy throughout the day, owing to disrupted sleep at night. As a result, people with dementia frequently take numerous, short nap opportunities throughout the day to make up for their lost rest at night. In addition to medically-defined sleep disorders, persons with dementia frequently experience other medical issues that disrupt their sleeping habits.

Obstructive sleep apnea is more common among persons with dementia who live in long-term care homes, according to a study published in the American Journal of Geriatric Psychiatry. The incidence of obstructive sleep apnea was estimated to be as high as 70% – 80% among people with dementia who lived in long-term care facilities, while the prevalence of sleeplessness among community-living persons with dementia was unknown (Ancoli-Israel, 2006).

Sleep apnea is an abnormal condition characterized by repetitive interruptions of sleep due to partial or full closure of the upper airways, accompanied by apneas (cessation of breathing) and hypoxemia (low oxygen levels). Body mass index greater than 38 kg/m2, prone sleeping position, and advanced age are all risk factors. Individuals with cognitive impairment have been shown to have periodic limb movements during sleep (PLMS), which are associated with shorter total sleep duration. PLMS as diagnosed by polysomnography or a “sleep study” have been found to occur in persons with cognitive decline and are predictive of reduced overall sleep time

The presence of pain has been linked to sleep disturbances, as well as depressive symptoms and decreases in quality of life, in older adults with cognitive impairment who live in nursing homes (Swafford et al., 2009). Environmental factors such on.

Assessment of sleep disturbances in persons with dementia

The first step in developing any nursing care plan is the nursing assessment, which provides the evidence for the development of therapies. The interview and a physical examination are often used to begin the assessment. If your client’s lack of sleep information is unreliable, speak with his or her relatives or caregivers.

Inquire about the patient’s sleep habits, history of sleep disorders, and any prescription or non-prescription drugs that have been used to promote sleep. Assess environmental, behavioral, and psychosocial factors that may be influencing poor sleep.

Conclusion

Dementia patients are known to experience a lot of sleep disturbances. This can be due to numerous factors, such as noise levels in nursing homes or difficulty maintaining a regular bedtime. However, there are ways that you can help dementia patients get the rest they need. Some suggestions include using white noise machines to drown out outside noises and keeping objects that provide a sense of security close by. A medical professional or sleep expert can provide personalized advice based on each individual’s specific circumstances. Implementing these tips may help improve the quality of life for dementia patients and their caregivers alike.
