A shift towards longer periods of sleep may indicate the early stages of dementia, according to a new study. The results were published in the Journal of Alzheimer’s Disease.
Researchers at the University of California, San Diego, studied the sleep patterns of more than 1,000 people with mild cognitive impairment (MCI) and found that those who slept less than seven hours a night had a higher risk of developing dementia than those that slept seven to nine hours per night.
This was true even when the researchers controlled for other factors such as age, gender, race, education, marital status, smoking, alcohol consumption, physical activity, depression, and other lifestyle factors. The researchers also found a link between sleep duration and the severity of the disease. Those who had slept fewer than eight hours were three times more likely to be diagnosed with MCI, compared to those with longer sleep durations.

What does it mean when an old person starts sleeping a lot?
Around 20% of older people experience excessive daytime sleepiness, which may be a sign of an underlying health condition rather than just old age. Older adults with health issues like sleep apnea, cognitive decline, or Alzheimer’s disease are more likely to have excessive daytime sleepiness. The best way to reduce your risk is to make sure you get enough sleep each night.
This is known as sleep inertia including memory loss – (See list below)
- Difficulty concentrating
- Poor decision-making
- Irritability
- Anxiety
- Depression
- Fatigue
- Headaches
- It can lead to a variety of problems
- Insomnia

Read on to learn more about how to get more sleep and what to do if you don’t. According to the Centers for Disease Control and Prevention (CDC), adults need between seven and nine hours of total sleep per night to maintain a healthy body weight.
At what stage of dementia do they sleep a lot?
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 become weaker and less able to cope with the demands of everyday life.
The study, published in the Journal of Alzheimer’s Disease, found that people who slept less than seven hours a night were more likely to develop dementia than those who had slept more than eight hours.
The researchers also found a link between sleeping less and the risk of developing dementia later in life, although the link was not as strong as previously thought.
Why does my 91 year old mother sleep all the time?
Some of the underlying causes of excessive daytime sleeping include boredom, depression, chronic pain and/or nutritional deficiencies. Sleep apnoea is a condition in which the airway (the tube that carries air from the lungs to the mouth and nose) becomes constricted during sleep.
It is most commonly caused by a blockage in the trachea (windpipe) or the bronchi (breathing tubes) that causes air to be unable to pass through the windpipe and into the nose and mouth. In some cases, the obstruction is so severe that breathing becomes difficult or even impossible. This condition is often referred to as apneas.
The most common symptoms are snoring, wheezing, shortness of breath, chest tightness, and difficulty breathing. If you experience any of these symptoms, it is important to see your doctor as soon as possible to rule out other conditions that may be causing the problem.
Your doctor may also recommend that you see a sleep specialist, who can help you determine the cause of your symptoms and prescribe a treatment plan that is best suited to your individual needs.
What time of day is dementia worse?
According to a new study published in the journal of the american geriatrics society, people living with alzheimer’s and other dementia may have problems sleeping or experiencing increased confusion, anxiety, pacing and disorientation beginning at dusk and continuing through the night.
The study, led by researchers at the University of California, San Francisco (UCSF), examined the sleep patterns of more than 1,000 people with mild cognitive impairment (MCI), a form of dementia that affects the brain’s ability to process information. MCI is characterized by memory loss, confusion and problems with thinking, language and motor skills, and is the leading cause of death in people over age 65.
It is estimated to affect about 1.5 million people worldwide. Researchers found that people who were diagnosed with dementia were more likely to be sleep-deprived than those who weren’t. In addition, those with the most severe dementia had the least amount of sleep, the researchers found.
The study was based on data from the National Health and Nutrition Examination Survey (NHANES), which is conducted by the Centers for Disease Control and Prevention (CDC) and the U.S.
How much sleep does a 72 year old need?
According to the CDC, older adults need about the same amount of sleep as everyone else. CDC recommends that adults get at least seven hours of uninterrupted sleep each night. That’s why it’s so important for older adults to get enough sleep. Sleep deprivation is associated with a host of health problems, including heart disease, stroke, diabetes, and Alzheimer’s disease.
It also increases the risk of falls and falls-related injuries, which can lead to serious injuries such as broken bones and even death. In fact, a recent study found that people who sleep less than 7.5 hours per night are more than twice as likely to suffer a fall as those who get eight hours or more.
Should you let a dementia patient sleep?
Patients with dementia might not be able to sleep at night. Before the diagnosis of dementia, it was best to keep the same sleep/wake times and routine. If the patient has a history of sleep apnoea, it is recommended that he or she be tested for apnea. Apnea is a condition in which the diaphragm (the muscle that controls breathing) does not work properly.
This can lead to breathing problems, such as shortness of breath, wheezing, chest tightness, and difficulty breathing in and out of the mouth and nose. If a patient is diagnosed with apneas, a sleep study should be performed to rule out other sleep disorders.
