The causes of Alzheimer’s disease are still undetermined to this day. Scientific research shows that people who are predisposed to long studies would be better protected against the disease.
Nearly 46 millions of Americans are at risk of Alzheimer’s disease according to a recent report. Yes the causes of the disease are yet to be established. A study by the International Genomics of Alzheimer’s Project shows that people with advanced degrees would be better protected against the disease.
Alzheimer’s disease is characterized by a slow degeneration of neurons. The degradation starts in the hippocampus region and gradually reaches the entire brain. 17,008 people with Alzheimer’s disease participated in the study, as well as 37,154 control subjects.
The results show that the level of education plays a role in the disease. Those who are predisposed by their genes to have higher degrees have the risk of Alzheimer’s reduced by 11% per completed year of study. If the individual reaches university, then the risk is reduced by 26%.
For the researchers, one of the explanations would be that these people have a “cognitive reserve”. It enables them to compensate for Alzheimer-induced brain degradation and to use other cognitive circuits.
Another factor could be linked to a decrease in the risk of Alzheimer’s: the level of genetically determined intelligence.
To prevent the disease and its acceleration, see your doctor at the first symptoms. When memory lapses become recurrent and frequent, a medical evaluation is required.
