sleeping less than 7 hours can increase the risk of developing the disease

We can never say it enough: it is important to sleep well, and for good reason. Lack of sleep can increase the risk of developing Alzheimer’s disease, according to the conclusions of a new scientific study.

We know that getting enough sleep allows the body to recover physically and mentally. What is less known is that lack of sleep can increase the risk of developing Alzheimer’s disease, according to a new study published in Brain Communications and reported by the Sun.

To reach this conclusion, the researchers analyzed the cerebrospinal fluid of 332 participants and found that those who slept less than 7 hours had increased levels of t-tau protein, a key biomarker for measuring Alzheimer’s risk. For researcher Laura Stankeviciute from the Fundación Pasqual Maragall in Barcelona, ​​this new study therefore reinforces the hypothesis that sleep disorders can constitute a risk factor for Alzheimer’s disease. She calls for “further research” into ways to improve sleep to stop this process.

devastating consequences

In the past, research had already highlighted the devastating consequences of a bad night on health. In particular, it had been proven that lack of sleep (sleeping five hours or less per night) could put individuals at a higher risk of developing several chronic diseases such as heart disease, depression, cancer or diabetes.

As a reminder, Alzheimer’s disease is a neurodegenerative pathology that leads to a dysfunction of the connections between neurons. Around 225,000 new cases are diagnosed each year in France. While the disease most often affects older people, it can also occur much earlier. According to figures reported by the Alzheimer Research Foundation, 33,000 patients, now under the age of 60, are affected.
