9 good habits to prevent Alzheimer's disease

Globally, it is estimated that in 2015 about 24 million people had dementias like Alzheimer’s disease and that number could triple by now 2050, placing a terrible burden on healthcare systems and the families of sufferers.

Dementia is the medical term used to describe brain damage that alters behavior, personality and overall cognitive functions. The most common form of dementia is Alzheimer’s disease, which is manifested by memory loss, difficulty performing simple tasks and increasingly strange behavior. Over time, the progression of the disease is accompanied by a marked deterioration in cognitive functions (impairments of language, visual recognition and integration of information) and, in more advanced stages, patients lose all interaction with the outside world until their death.

Preventing and slowing the progression of Alzheimer’s disease

Until very recently, Alzheimer’s disease was considered to be the consequence of two main factors: aging and the presence of certain genes that predispose to developing the disease. These two factors do play a role: for example, it is well documented that people who have the ApoE4 variant are at higher risk of dementia, but this gene is only responsible for about 7% of Alzheimer’s cases and other factors are clearly at play. Even downside for aging: age is of course an important risk factor, but several recent observations nevertheless indicate that Alzheimer’s disease is not an inevitable consequence of aging and that many aspects of lifestyle can also hugely influence its progression. disease by changing lifestyle habits.

The 9 habits to put in place to prevent Alzheimer’s disease

It is in this context that a group of 24 international experts recently published linked an update of the main factors that can reduce the risk of developing dementia in general, including Alzheimer’s disease. The rigorous analysis of the studies accumulated up to now leads the authors to propose that the modification of nine main risk factors can significantly reduce the incidence of these diseases.

– Quit smoking. Smoking has a devastating effect on cardiovascular health, causing a decrease in oxygen supply to the brain and damaging neurons. Certain neurotoxins in tobacco also contribute to this damage.

– Exercise. Physical activity exerts a neuroprotective action due to an improvement in the circulation of blood in the brain as well as by stimulating the growth of neurons involved in memory processes.

– Maintaining a healthy weight. Several studies show that obese people are at higher risk of dementia, a consequence of the negative impact of being overweight on chronic inflammation and oxidative stress which disrupt the whole body, including the brain.

– Control blood pressure. Hypertension creates mechanical stress on blood vessels which increases the risk of neurodegeneration and, consequently, dementia.

– Control blood sugar. People with diabetes are at higher risk of dementia because chronic hyperglycemia is very toxic to cells, including neurons.

– Treat depression. Depression affects the levels of several stress hormones as well as the structure of certain parts of the brain (hippocampus), which could accelerate the development of dementia.

– Maintaining a social network. Social isolation and loneliness are important risk factors for hypertension, cardiovascular disease and depression, three conditions that have been linked to the development of dementias.

– Continue Learning . Education helps create what is called a “cognitive reserve” that maintains brain function despite deterioration of neurons.

– Make sure you hear well. It may seem surprising, but several studies have shown that there is a strong correlation between deafness and the risk of dementia. The mechanisms involved remain poorly understood, but it is likely that hearing stimulates intellectual functions and thus delays the deterioration of neurons. According to the researchers, the use of hearing aids by people who cannot hear well could help reduce this risk.

Turmeric, red wine and Tea green against Alzheimer’s disease

It should be noted that this reduction in dementia using the factors of the lifestyle that we come from to list is a minimum and could even be more pronounced than what is mentioned here. Several more recent population studies suggest that the consumption of certain foods such as turmeric, red wine, cocoa or even green tea is associated with an even more marked reduction in the risk of cognitive decline and the inclusion of these foods in eating habits could further increase our protection against dementias such as Alzheimer’s disease.
