Dementia is a collective term that describes various symptoms of a cognitive decline such as forgetfulness. It is a symptom of various underlying diseases and brain disorders. These have a negative effect on the body. If you suffer from this sleep disorder, it can be an early warning of a progressive disease.
One of the first signs that may indicate a problem with the brain, such as: B. Dementia can be an interruption in sleep patterns.
The suprachiasmatic nucleus (SCN) in the hypothalamus of the brain is responsible for controlling our sleep-wake patterns.
This is often referred to as the circadian rhythm because its patterns last for almost a day.
With many types of neurodegenerative diseases, as well as movement disorders such as Parkinson's disease, certain areas of the brain can degenerate over time.
Brain cells can become less sensitive to chemicals called neurotransmitters and build up, disrupting their function.
If the SCN is lost, a person's ability to maintain a normal sleep-wake pattern is compromised.
This can manifest itself in various circadian rhythm disorders.
Older adults often suffer from advanced sleep phase syndrome, which includes the desire to go to bed early and get up.
The change in the sleep schedule can be beyond a person's control and represent changes in the brain with age.
In a study, 145 volunteers from the Charles F. and Joanne Knight Alzheimer Research Center at the university were recruited.
The volunteers were between 45 and 75 years old and had normal cognitive function.
Participants kept daily sleep logs for two weeks, noting when they went to bed and getting up, how many naps they had taken the night before, and other relevant sleep-related information.
The researchers tracked participants' activity levels using wrist-worn sensors that track user movements.
The author of the study, Dr. Yo-El Ju, an assistant professor of neurology, said: "Most people do not move during sleep and we have developed a way to use the data we collect to determine whether a person has been asleep or not." Awakening .
"In this way, we can assess the effectiveness of sleep, which measures the time we spend in bed.
"When we look specifically at those who sleep the poorest, people with less than 75% sleep efficiency were more than five times more likely to have Alzheimer's disease than people who sleep well."
Pinnacle Care said: "Over 80% of older men with a sleep disorder known as Rapid Eye Movement Sleep Disorder (RBD) have developed a neurodegenerative disorder that includes Alzheimer's disease, body dementia. Lewy and Parkinson Disease, in a small study.
"Other researchers are studying the relationship between daytime disorders, sleep disorders, and an increased risk of Alzheimer's.
"Previously, it was thought that sleep problems in people diagnosed with Alzheimer's were caused by the disease, but new research suggests that certain sleep disorders can contribute to the development of Alzheimer's."
