Dementia and sleep are essential factors in ensuring the good condition of the brain and the processes of its activity, memory, mood, and overall functioning. But dementia may affect the natural process of sleeping and make some difficulties for people and their families. While some people face the problem of nighttime awakening, others have excessive daytime sleeping or even insomnia.
The knowledge of the relations between dementia and sleep can be useful to recognize the problems in sleep and find out ways to solve them. At MAVA Behavioral Health, the importance of the cognitive and emotional health of people struggling with the issues of sleep and dementia is still high. In the current guide, we will talk about the most popular sleep disorders, their causes, and treatments.

What Is the Connection Between Dementia and Sleep?
The poor sleep and dementia connection is mutual in nature. The condition of dementia may interfere with the brain mechanisms that help maintain wakefulness and sleep, whereas poor sleep may have an impact on memory and attention. The brain needs a regular cycle of sleep to be able to consolidate memory and to perform other necessary functions.
Dementia affects the areas controlling the body’s internal clock, resulting in irregular sleep patterns or daytime drowsiness. A poor dementia and sleep relationship implies changes in the brain capacity to maintain sleep stage consistency. Poor sleep doesn’t necessarily mean dementia, but if it is accompanied by problems with memory, one should consult a doctor.
How Dementia and Sleep Patterns Change Over Time
Persons suffering from dementia are likely to exhibit various changes in their sleep cycle patterns. The changes will depend on the kind of dementia, general condition of the patient, medications that he or she is taking and the degree of cognitive decline suffered.
These changes may include the following:
- Problems getting to sleep during nighttime.
- Multiple wake-ups during nighttime.
- Early wake-up in the morning.
- Late sleeping during the day.
- Restlessness or confusion during nighttime.
Individuals suffering from sundowning syndrome suffer from confusion, agitation or restlessness late afternoon and at night. This is mainly due to fatigue, light changes and disturbances of the body internal clock.
dementia and Lack of Sleep What You Need to Know
It is vital to look at the connection between insomnia and dementia. Studies have found that poor sleep influences one’s cognitive function and increases the chances of cognitive decline but doesn’t necessarily prove dementia. While sleeping, the brain helps to learn, remember, and perform cellular functions. If an individual is constantly deprived of sleep, he or she may have difficulties concentrating, become forgetful, suffer from mood swings,
be less alert, and have difficulty performing usual daily activities. The connection between dementia and insomnia is crucial for those with cognitive impairment, as it can cause confusion, impair daytime performance, and increase stress on carers.
Deep Sleep and Dementia: Why Sleep Quality Matters
Deep sleep contributes to recovery, memory, and brain health. In addition, scientists study the role of deep sleep in waste disposal from the brain and its potential connection to the development of Alzheimer’s disease. It is possible that some researchers have found out the relation between a decrease in slow-wave sleep, which is the form of deep non-REM sleep, and the risk of cognitive impairment, but it does not mean that poor quality of deep sleep causes dementia.
People with dementia may have alterations in the sleep pattern, like nocturnal awakenings and fragmented sleep, which influence the wakefulness, mood, and cognition during the day. To promote healthy sleep, a person can maintain consistent bedtimes, exercise safely during the day, get natural sunlight, limit afternoon and evening caffeine, and create a peaceful bedroom. Also, it is possible to avoid excessive and long napping in the afternoon.
Dementia and Sleeping a Lot: When Does Excessive Sleep Become a Concern?
Dementia and excess sleeping are issues that are often brought up by the people around an individual with this disease. It is common for some people with dementia to sleep for more hours during the night and nap a lot during the day, or they seem very drowsy all the time.
The issue of excess sleep may be caused by various factors such as changes in brain activity, lack of stimulation, medications, depression, and other illnesses.
Too Much Sleep and Dementia: Possible Causes
Too much dementia and sleep can coexist, although too much sleepiness is not necessarily caused by dementia. Sedative drugs, sleep apnea, other sleeping problems, infections, illness, dehydration, poor nutrition, depression, and limited physical activity can cause too much sleepiness. Problems associated with sleep at night could also cause drowsiness during the day and naps.
Seek urgent medical attention if rapid changes in sleep patterns accompany confusion, weakness, fever, or decreased alertness. Healthcare providers can monitor sleep patterns, naps, medication adjustments, and behavior to determine possible causes and offer appropriate care.
Sleep Apnea and Dementia: Understanding the Overlap
Sleep apnea refers to a sleep disorder characterized by breathing cessation during sleep. The most prevalent type of sleep apnea is obstructive sleep apnea, which results from repeated narrowing or closing of the upper airway during sleep. Sleep apnea and dementia may overlap due to their effects on cognitive functions, daytime alertness, and quality of life. There is scientific evidence suggesting a relationship between obstructive sleep apnea and cognitive decline. However, this association does not mean that sleep apnea causes dementia.
Some of the common signs of sleep apnea include loud and habitual snoring, breathing cessation during sleep, gasping or choking in sleep, headaches in the morning, extreme fatigue during the day, and problems with concentration. If such signs appear, it is advisable to conduct a sleep study to diagnose the problem. Possible treatments of sleep apnea include CPAP treatment, among others. Nevertheless, treating sleep apnea will not necessarily prevent or reverse dementia.
What Stage of Dementia Is Not Sleeping?
There is no one stage where there are sleep disturbances. Sleep disturbances can occur during any stage of dementia, depending on the type and nature of the disturbance.
1. Early Stage of Dementia
During the early stage of dementia, the individual may suffer from minor insomnia or sleep disturbances. There might be memory problems and issues related to anxiety in relation to day-to-day activities.
2. Middle Stage of Dementia
In the middle stage of dementia, the individual might face sleep disturbances in the form of sundowning, night-time wandering, confusion, and so forth.
3. Late-stage dementia
In late-stage dementia, a patient’s sleep/wake pattern may be highly disordered. It is common for some patients to sleep for a long time, wake up frequently, or switch from prolonged sleeping spells to waking spells.
Should a patient cease sleeping altogether, develop agitated behavior, or undergo sudden behavioral changes, medical advice should be sought rather than assuming that this is part of dementia.
Sleep Aids and Dementia: What Treatment Options Can Help?
Sleeping pills and dementia must be thought about carefully since some sleep medicines could make people confused, fall, sleepy during the day, and so on.
What to do will depend on the symptoms that the patient experiences, their past and present illnesses, as well as the type of dementia.
What Is the Best Medication for Sleep for Dementia Patients?
There is no universally best medicine for sleep in dementia patients. The safest treatment will depend on the cause of the sleep problem and the general state of the person’s health.
The clinician can choose from the following options:
- Melatonin: Some patients may use melatonin to treat specific sleep disorders.
- Sleep medication: A certain drug might work in treating a particular disorder; however, the risk associated with such medications should be carefully considered.
- Treatment of underlying disorder: Pain relief, antidepressants, and treatment of anxiety or sleep apnea, can improve sleep without sleep medication.
- Behavioral treatments: Routine, exposure to daylight, and proper physical activity can serve as a first step towards improvement.
Some drugs, like benzodiazepines and antihistamines, can cause confusion and increase the risk of falling in elderly patients. Clinicians rarely prescribe such medicines to patients with dementia.

Some Practical Methods of Improving Sleep and Dementia Symptoms
Even though the symptoms of dementia could make sleep hard to attain, having a consistent routine could be beneficial in this case.
1. Maintain a Regular Sleeping Pattern
It could be encouraged that the individual wake up and sleep at the same times each day, which will help establish their biological clock.
2. Exercise in the Daytime
This could include simple exercises like walking, doing chair exercises, gardening, and other types of exercises suitable for the individual.
3. Have More Exposure to Natural Light
Morning light exposure will assist in regulating circadian rhythms. Even though outside activity might not be possible, light exposure through a window could still help.
4. Have an Uncomplicated Evening Environment
Having reduced noise and avoiding stimulating activities before sleep and making sure there is comfortable lighting.
5. Consider Naps and Caffeine
Extended naps during the day could affect sleep at night. Restricting caffeine intake, especially towards the evening, is another helpful step; however, individual requirements differ.
6. Ensure Safety at Night
Employ night lights, safe walking paths, and adequate supervision in case there are risks associated with nocturnal wandering. The bedroom should be comfortably warm and easy to reach from the bathroom.
7. Get Professional Advice
A specialist can assess cases of insomnia, oversleeping, suspected sleep apnea, pain, side effects of medications, and abrupt changes in behavior.
The MAVA Behavioral Health center is a good starting point for families needing information on cognitive and behavioral health.
When Should You Seek Medical Help?
See a healthcare provider if sleep issues continue, if they affect your ability to function normally on a day-to-day basis, or if they cause you or a carer distress.
If there are sudden symptoms such as confusion, a sudden drop in alertness, trouble breathing, and any others that require immediate medical attention, then a visit to the doctor should be made because they could suggest delirium, an infection, drug side effects, or a medical condition, not a slow-onset condition of dementia.
Conclusion
The interaction between dementia and sleep revolves around the altered sleep-wake cycle within the brain, everyday activities, side effects of medications, and co-occurring ailments.
Sleeping at regular times, being active during the day, exposure to natural sunlight, security at night, and proper treatment can solve several difficulties related to sleep. It is necessary for the family members of the individual with dementia not to forget that sometimes sleep disturbances can lead to some medical issue. MAVA Behavioral Health promotes greater awareness regarding cognitive and behavioral health issues to get guidance on this matter.
