The risk of dementia depends on cholesterol

Hold cholesterol at low levels reduces the risk of dementia. These are the results of DNA research more than half a million people.

The same genetic risk factors that make people vulnerable to high cholesterol levels, can increase the risk of developing Alzheimer’s disease, as shown by a new study. Causes dementia is still unknown, but scientists from the University of Washington and the University of California in San Francisco conducted the largest to date, the study of DNA to search for pre-programmed risk factors. Science has known that there is one gene associated with Alzheimer’s disease, which encodes a molecule involved in the movement of cholesterol throughout the body.

However, the relationship between cholesterol and senile dementia may be more durable than it previously accepted. In the new genetic analysis, scientists have discovered that a small group of genes associated with increased risk of Alzheimer’s disease, and heart disease. The prevalence of dementia continues to grow as the population in many countries of the world today lives longer. The increase in life expectancy means that the increase in the number of age-related diseases, including dementia and cardiovascular disorders.

It is possible that the development of these diseases can be partially predicted by our genes before human will be born. Moreover, due to some specific genes. For example, the APOE4 variant of the gene is now considered one of the risk indicators of Alzheimer’s disease. It is associated with a fourfold increase in the likelihood of a person’s episodes of dementia. Scientists are trying to find other similar genes, so in the future could influence them. (READ MORE)
