American researchers have recently identified two new risk factors for Alzheimer’s disease. According to them, visual loss and high rates of “bad” cholesterol could be a harbinger of the disease. We explain why.

Hearing and vision loss

Age, a low level of educationthe smokinga high blood pressure untreated… Many factors leading to Alzheimer’s disease are now well established. But this neurodegenerative pathology is revealed little by little and new risks appear.

Researchers from the Cleveland Clinic (Ohio, United States) have just highlighted two new risk factors.

The first is vision loss who, like the hearing losswould expose you more to the disease. The other risk factor is a high level of LDL cholesterol, in short, bad cholesterol.

Although the exact mechanisms linking these health problems to Alzheimer’s disease are not yet fully understood, several hypotheses are put forward.

Prevention above all

Vision loss could affect sensory input of a person, thereby reducing the amount of information processed by the brain. Additionally, it could limit the ability to exercise, socialize, or engage in stimulating activities. All are important factors for good cognitive health.

Regarding the cholesterolthe authors emphasize its negative impact on the heart and blood vessels. The brain, rich in small blood vessels, would therefore be particularly vulnerable to the effects of high levels of LDL cholesterol.

“If a person suffers from vision loss or high LDL cholesterol, the key is to seek treatment,” insist the researchers. “If you are concerned about your vision, see your eye doctor. »

“If you have a high LDL level, or if it is a hereditary disease, it is important to consult regularly. And if your doctor recommends a suitable diet, exercise or medication, follow his advice. »
