What You'll Learn
Excessive sleep is an early sign of dementia
There are several reasons why people with dementia may sleep more. Firstly, as the disease progresses, the damage to the brain becomes more extensive, and patients gradually become weaker and frailer. Simple tasks like communicating, eating, or understanding their surroundings can become exhausting, leading to increased sleep during the day and night. Secondly, dementia disrupts sleep patterns by interfering with the brain's regulation of the sleep-wake cycle, leading to greater interruptions in the cycle and more daytime drowsiness and sleeping.
Additionally, neurological factors play a role in the increased sleep seen in dementia patients. Changes in the levels of neurotransmitters and alterations in brain structures and functions related to sleep regulatory regions can contribute to longer sleep patterns. Furthermore, medication side effects and environmental stimuli can also influence sleep patterns in people with dementia. For example, certain medications can cause increased sleepiness, and environmental factors such as lighting or noise can impact sleep duration and quality.
It is important to note that while excessive sleep may be an early sign of dementia, it is not the only factor. Other cognitive or behavioural issues should be present alongside excessive sleep for it to be a potential indicator of dementia. If you or someone you know is experiencing unusual sleep patterns and other concerning symptoms, it is recommended to speak to a doctor for a proper diagnosis and to rule out other possible causes.
Understanding why dementia patients experience excessive sleep is crucial for caregivers and family members. By recognizing the connection between sleep patterns and dementia, preventative strategies and interventions can be developed to improve the overall well-being of those affected by the disease.

Prolonged sleep duration as a marker of early neurodegeneration
Excessive sleep is a common symptom of dementia, especially in the later stages of the disease. This can be distressing for friends and family, who may worry that something is wrong. People with dementia may find simple tasks like communicating or eating exhausting, which can lead to them sleeping more.
Prolonged sleep duration may also be a marker of early neurodegeneration, indicating an increased risk of developing clinical dementia within 10 years. This is supported by a study that found an association between long sleep duration and a higher risk of all-cause dementia. The study examined self-reported sleep duration in the Framingham Heart Study, with sleep categorized as <6 hours (short), 6-9 hours (reference), and >9 hours (long). The results showed that transitioning to sleeping >9 hours was linked to a higher risk of dementia. However, it is unclear if abnormal sleep duration is a risk factor or an early marker of neurodegeneration.
Several factors contribute to the prolonged sleep patterns observed in dementia patients. Physiologically, dementia disrupts the sleep-wake cycle by interfering with the brain's regulation. This disruption can lead to greater interruptions in the sleep-wake cycle, resulting in more daytime drowsiness and extended periods of unrestful sleep. Neurological differences also play a role, with a direct correlation between the quality and quantity of sleep and changes in the brain, such as an increase in beta-amyloid plaques and tau protein tangles. Additionally, environmental factors, medication side effects, and psychiatric comorbidities can influence sleep patterns in dementia patients.
While excessive sleep can be a symptom of dementia, it is important to note that it does not necessarily indicate dementia by itself. Other health issues, sleep problems, and medication side effects can also contribute to prolonged sleep. However, when combined with other cognitive or behavioral issues, it may be a sign of early-stage dementia or neurodegeneration.

The impact of changing sleep patterns on quality of life
The impact of changing sleep patterns can have a significant influence on the quality of life for those with dementia and their caregivers. As dementia progresses, patients experience greater interruptions in their sleep-wake cycle, leading to more daytime drowsiness, inattentiveness, and extended periods of unrestful sleep. This can be distressing for caregivers, who may worry that something is wrong or that it indicates a steeper cognitive decline.
The excessive sleeping seen in dementia patients is influenced by a combination of physiological, neurological, and environmental factors. Physiologically, dementia disrupts sleep patterns by interfering with the brain's regulation of the sleep-wake cycle. This is due to neurological changes, such as an increase in beta-amyloid plaques and tau protein tangles, which directly correlate with the quality and quantity of sleep.
Neurological differences and malfunctions in the brain's regulatory functions can also play a role. For example, in Lewy body dementia, daytime sleepiness is common, even before significant cognitive decline occurs. Additionally, medication side effects and environmental stimuli can further disrupt sleep patterns, making it challenging for patients to establish a healthy sleep routine.
The impact of these changing sleep patterns can be far-reaching. For the patient, it may result in a decrease in overall well-being, as they may become weaker and frailer, experiencing exhaustion from performing simple tasks. It can also impact their caregivers, who may need to adjust their routines and provide additional support to ensure the patient's needs are met.
However, it is important to note that while sleeping a lot can be a symptom of dementia, especially in the later stages, it is not always cause for concern. Sleeping more can be a natural progression of the disease, and as long as the patient maintains a small routine and eats regularly, it may be best to let them rest. Nevertheless, any sudden changes in sleep patterns or consciousness should be addressed by a medical professional, as they could indicate a problem with medication, illness, or another complication.

Lewy body dementia and daytime sleepiness
People with dementia often spend a lot of time sleeping, which can be worrying for their carers, friends, and family. This is especially common in the later stages of the disease when the person with dementia may find simple tasks like communicating or eating exhausting.
Lewy body dementia (LBD) is a type of dementia that is characterised by disturbances of sleep and/or arousal, including insomnia, excessive daytime sleepiness, rapid eye movement (REM) sleep behaviour disorder, obstructive sleep apnea, and restless leg syndrome. These sleep disorders are quite common in LBD, and many of them are treatable.
Research indicates that daytime sleepiness is more likely to occur in people with LBD than in those with Alzheimer's disease. In LBD, daytime sleepiness is often present early in the disease, even before significant cognitive decline occurs. Sleep disorders can negatively impact the quality of life of both patients and caregivers, but their causes are poorly understood, and they remain under-diagnosed and under-treated.
Daytime sleepiness in LBD can be caused by the same sleep issues that affect the general population, such as insomnia, sleep apnea, and restless legs syndrome. However, when these issues occur in individuals with LBD, they can disrupt nighttime sleep and contribute to excessive sleepiness during the day. Additionally, people with LBD may shout or move around in bed while appearing to act out a dream, a disorder known as REM sleep behaviour disorder (RBD). RBD can be either mild or vigorous and may lead to injury to the person with RBD or their bed partner.
If you or someone you know is experiencing excessive daytime sleepiness and is concerned about the possibility of Lewy body dementia, it is recommended to seek advice from a clinician knowledgeable in sleep medicine.

Vascular dementia and sleeping more than usual
People with dementia often experience changes in their sleep patterns, including excessive sleeping during the day and night. This is quite common in the later stages of dementia as the disease progresses and the person's brain becomes more extensively damaged, making even simple tasks exhausting.
Vascular dementia, in particular, has been linked to excessive sleeping. This type of dementia is usually triggered by underlying conditions such as cardiovascular diseases or diabetes, and the initial medications prescribed often target these concerns. For example, physicians may prescribe blood thinners or diabetes medications to stabilize the patient's health and prevent further damage. However, these medications can sometimes cause drowsiness or insomnia, contributing to the person's sleepiness during the day.
Additionally, vascular dementia can deteriorate more quickly than other types, and a sudden increase in sleepiness could indicate an underlying problem. For instance, the person may have had another stroke, or the underlying condition causing their vascular dementia may have worsened. In such cases, infections can also exacerbate dementia symptoms, causing delirium similar to hallucinations or delusions in the later stages of dementia.
There are several strategies to manage excessive sleeping in people with vascular dementia:
- Routine changes: If daytime sleepiness occurs due to disturbances or insomnia at night, focus on improving nighttime sleep. This can include avoiding caffeine, establishing a relaxing nighttime routine, and creating a quiet and comfortable bedroom environment.
- Daytime activity and light exposure: Increasing physical activity and light exposure during the day may help regulate sleep. Doing more activities outdoors can be beneficial if the person spends a lot of time indoors.
- Medications: While there are no specific drugs to treat excessive sleeping in vascular dementia, low doses of mirtazapine, an antidepressant, can be used as a sleep aid. For those with co-occurring Parkinson's disease, modafinil (Provigil) may improve drowsiness. Additionally, melatonin has been found to help regulate sleep patterns in people with dementia.
Excessive sleeping in people with dementia can be distressing for caregivers, who may worry about the person's well-being. It is important to understand the reasons behind these changing sleep patterns to develop effective strategies for addressing this issue and improving the overall well-being of both the person with dementia and their caregivers.
