Alzheimer : a scourge growing or declining?
Experts believe Alzheimer’s, a complex neurological disease related to age, could be influenced both genes and by Environment.
With the boom in population and increased life, considering that 106 million people will have Alzheimer’s by 2050 against 30 million in 2010, according to estimates made in 2007.
In France, it is the fourth leading cause of death in 2008 after cancer, cardiovascular diseases and accidents.
Alzheimer’s disease and other dementias increased 71.8 % since 2000, according to the study published in September 2013 in the Weekly Epidemiological Bulletin.
In 2010, it was estimated that 750,000 to 1 million French were affected, prevalence is expected to reach between 1.29 and 1.40 million people in 2030.
However, these data remain extrapolations from some records, because ” There is no monitoring of the incidence and prevalence of these diseases “.
But this strong progression of Alzheimer ‘s disease is not the only case, as a study presented at the Congress of the Alzheimer’s Association International shows a die, twinkling in the prevalence of this disease.
Following the large cohort of patients Framingham, the authors were able to show that during the last three decades, the risk of developing the disease is declining.
This trend could be related to educational factors, reducing cardiovascular risk factors and a better lifestyle at least in developed countries.
These indications suggest that Alzheimer’s disease can be prevented.
Alzheimer’s disease can be prevented?
In this regard, a study by Carol Brayne, Professor of Health public Service University Cambridge, says that millions of Alzheimer’s cases could be prevented if patients changed their lifestyle.
This work is based on the use of a mathematical model based 7 risk factors with a proven link with the disease: diabetes, hypertension and obesity appeared in mid-life, inactivity physical, depression, smoking, and low level of education.
According to its results, the reduction of each of these risk factors by 10% would reduce the extent of Alzheimer 8.5% by 2050, thereby avoiding 9000000 patients.
In 2011, some experts considered that two cases of Alzheimer could be prevented thanks to changes in lifestyle and personal well -being, a notice relativized this new study finds that this proportion is too high, given some risk factors overlap.
For example, diabetes, hypertension and obesity are linked to inactive physical, and all are influenced by the level of education.
” Although there is no one way to prevent dementia, we would be able to reduce the risk of being victimized when you are old ” said Brayne in a statement issued by the University Cambridge.
“We know that many of these factors are often related.
If we simply attack inactive physics, for example, could reduce levels of obesity, hypertension, diabetes, and prevent dementia some people while providing them better health as seniors – it’s win-win “.
