Sleep Problems Can Be Alzheimer’s Signs

New research in the US found that sleep problems in healthy people can be an indicator that they may continue to develop Alzheimer’s disease later in life. The University of Wisconsin-Madison has conducted research on this and demonstrated the quality of sleep can be attributed to the disease.

“Previous evidence has shown that sleep can affect the development or progression of Alzheimer’s disease in various ways,” explains study author Barbara B. Bendlin, PhD. “For example, deep sleep or lack of sleep can cause amyloid plaque buildup due to the brain. The clearance system begins during sleep. Our study not only looked at amyloid but also for other biological markers in spinal fluid.

Amyloid is a protein that can fold and form plaque in the brain, while other proteins, Tau, are formed into tangles. Both plaque and tangles are found in the brains of Alzheimer’s disease.

For the new study, the team recruited 101 people with an average age of 63 people who had normal thinking and memory, but were at risk for Alzheimer’s disease.

Participants provided information on the quality of sleep and their spinal fluid samples, which then tested the biological markers of Alzheimer’s disease, including amyloid signs, tau and brain cell damage and swelling

The results, published in the online edition of Neurology, the medical journal of the American Academy of Neurology, show that those who report poorer sleep quality, more sleep problems and daytime sleepiness have more biological markers for Alzheimer’s disease in their spinal fluid than people people who have no sleep problems

The results remain valid even after researchers take into account other factors such as drugs for sleep disorders, education, depressive symptoms or body mass index.

However, not everyone who has sleep problems has a biological marker in their spinal fluid, with the team finding no association for obstructive sleep apnea sleep problems.

Bendlin noted that, “It remains unclear whether sleep can affect the progression of the disease or if it affects sleep quality, and further research is needed to determine the relationship between sleep and this biomarker.”

Moreover, he also added, “There are already many effective ways to improve sleep, and perhaps early intervention for people at risk for Alzheimer’s disease may prevent or delay the onset of the disease.”

Alzheimer’s is such a terrifying disease. My nana has it and during COVID, she’s really been deteriorating mentally, as we’re not allowed to take her from the senior residence she’s staying at, for safety reasons. It’s so sad to watch…

Sleep problems and Alzheimer’s have been bothering many people, especially old people. I have relatives suffering from them. It’s really important to analyse the patients and look for treatments.


I have sleep problems specially when I feel stress and anxieties this is so worrying for everyone. I only think Alzheimer’s is only for sign of aging.


I knew it! There is literally no way you can remember (vividly or partially) something you have to do, without resting your mind and body, in general! Be ware!


My partener has really big sleeping problems. Sometimes he hardly sleeps 2 hours per night. This article made me think…

I am more afraid of Alzheimer’s than cancer. Losing my memories and events in my life will be devastating than undergoing chemotherapy.


That is so scary! I have always been terrified of getting this disease. It just takes away everything you ever were. I had no idea sleep problems were associated with it.


This is a very interesting idea. I know that sleep is how the body repairs itself, so it makes sense to me that disrupted sleep my contribute to, or make worse, alzheimers.

Alzheimer’s is such a terrifying disease, and this study is really interesting. Hopefully screening people for sleep issues will help prevent or delay the disease in those who might be susceptible.


I didn’t know that any sleep problems could be related to any symptoms of this terrible disease. I will deepen the topic!


This is such useful information to know. A very insightful read — definitely some stuff I had never thought about myself! Thanks so much for sharing this.


This is so interesting to find out!! It runs in my family so I always am looking for signs!

It’s a really worth reading article. I have trouble sleeping, especially when I feel stressed and anxious. This is so worrying for everyone. I just think Alzheimer’s is just a sign of aging.
