Sleeping more and more is a common feature of later-stage dementia. As the disease progresses, the damage to a person's brain becomes more extensive and they gradually become weaker and frailer over time.
As people age, they tend to sleep more lightly and often awaken during the night from achy joints or the need to go to the bathroom. Many people compensate for this lost sleep by catching a restorative nap during the day. That's normal.
Sleep and Aging
Older adults need about the same amount of sleep as all adults—7 to 9 hours each night. But, older people tend to go to sleep earlier and get up earlier than they did when they were younger. There are many reasons why older people may not get enough sleep at night.
Some sleep experts suggest that seniors actually need less sleep than other age groups. Most people need between 7 and 9 hours of sleep whereas many seniors can get away with 7.5 hours. Other experts believe that seniors need just as much sleep as the rest of the population.
Almost all older people sleep more than the average adult. This is because sleep helps maintain our physical and psychological health. Sleeping also improves memory and slows down the process of aging. To stop the effects of aging, we need to sleep more.
Sleeping more and more is a common feature of later-stage dementia.
Excessive sleepiness in older adults is often multifactorial and may signal an underlying sleep disorder, chronic medical condition, undiagnosed mood disorder, or side effects of medications. It is associated with increased risk for cognitive decline and dementia in the elderly.
It is quite common for a person with dementia, especially in the later stages, to spend a lot of their time sleeping – both during the day and night. This can sometimes be distressing for the person's family and friends, as they may worry that something is wrong.
Vitamin B12 Deficiency: A Rare Cause of Excessive Daytime Sleepiness.
Excessive sleep causes inactivity that causes low energy levels, constant grogginess and brain fog. Loss of energy is likely to make the senior less willing to perform necessary physical therapy exercises properly, and this can lead to diminished health and shorter lifespans.
Compared with younger adults, the elderly spend more time in bed but have deterioration in both the quality and quantity of sleep. All of these changes can lead to excessive daytime sleepiness, which in turn can lead to intentional and unintentional napping.
Sleep Changes in Older Adults. Most healthy older adults aged 65 or older need 7-8 hours of sleep each night to feel rested and alert. But as you age, your sleep patterns may change. These changes can cause insomnia, or trouble sleeping.
The panel found that while sleep patterns change with aging, adults 65-years-old and older still need between 7-8 hours of sleep nightly, and ideally over a continuous period of time.
Around 20% of older people experience excessive daytime sleepiness, which may be a sign of an underlying health condition. Excessive daytime sleepiness in older adults may be a symptom of health issues like sleep apnea, cognitive impairment, or cardiovascular issues.
Experts recommended that adults 65 and older get 7-9 hours of sleep each night. However, quantity of sleep may not be as crucial as quality: getting a good night's sleep is imperative to healthy aging. Notably, older adults need enough deep sleep to help their bodies function.
The Centers for Disease Control and Prevention defines an “older adult” as someone who is at least 60 years old. Many states may also have different definitions of “elderly” when determining what resources are available in cases of elder abuse, although most states commonly use 65 years of age as the cut-off.
Vitamin B12
Vitamin B12 is essential for the production of red blood cells and DNA. It is also essential for the functioning of the nervous system. When your body does not receive enough vitamin B12 you may feel fatigued and tired all the time.

Too much sleep and time in bed (TIB) may raise the risk of developing dementia and Alzheimer's disease (AD), new research suggests.
One of the most common causes of death for people with dementia is pneumonia caused by an infection. A person in the later stages of dementia may have symptoms that suggest that they are close to death, but can sometimes live with these symptoms for many months.
Administration: The examiner reads a list of 5 words at a rate of one per second, giving the following instructions: “This is a memory test.
