Alzheimer’s disease is a neurodegenerative disorder that affects millions of older adults worldwide. It is a progressive disease that affects thinking, memory, and behavior, and can eventually lead to complete loss of independence.

As researchers continue to study this disease, new risk factors are being discovered, including excessive daytime sleeping in older adults.

What is Alzheimer’s Disease?

Alzheimer’s disease is a brain disorder that affects memory, thinking, and behavior. It is a progressive disease that gets worse over time. Alzheimer’s is the most common form of dementia, accounting for up to 80% of all dementia cases.

The exact cause of Alzheimer’s disease is not known, but it is believed to be caused by a combination of genetic, environmental, and lifestyle factors.

The Link Between Excessive Daytime Sleeping and Alzheimer’s Disease

Researchers have found a link between excessive daytime sleeping and an increased risk of Alzheimer’s disease in older adults.

In a study published in JAMA Neurology, researchers analyzed data from 283 older adults without dementia who were followed for an average of 5 years. The researchers found that those who reported sleeping excessively during the day were more likely to develop Alzheimer’s disease compared to those who did not report excessive daytime sleepiness.

How Does Excessive Daytime Sleeping Affect the Brain?

Excessive daytime sleeping can affect the brain in several ways. One theory is that it disrupts the natural sleep-wake cycle, which can affect the brain’s ability to clear out waste and toxins.

During sleep, the brain flushes out toxins and waste products that build up during waking hours. If this process is disrupted, it can lead to a buildup of amyloid beta protein, which is a hallmark of Alzheimer’s disease.

Other Risk Factors for Alzheimer’s Disease

While excessive daytime sleeping is a newly discovered risk factor for Alzheimer’s disease, there are several other known risk factors, including:.

Age
Family history of the disease
Down syndrome
Cardiovascular disease
Head trauma

Preventing Alzheimer’s Disease

While there is no known cure for Alzheimer’s disease, there are several ways to reduce your risk, including:.

Eating a healthy diet
Exercising regularly
Maintaining a healthy weight
Not smoking
Limiting alcohol consumption
Keeping your brain active through activities like reading, puzzles, and socializing

Conclusion

Excessive daytime sleeping may increase the risk of Alzheimer’s disease in older adults. This newly discovered risk factor adds to the growing list of known risk factors for this devastating disease.

While there is no known cure for Alzheimer’s disease, taking steps to reduce your risk, such as eating a healthy diet, exercising regularly, and keeping your brain active, can help improve your overall health and well-being.
