Japanese researchers discover link between cholesterol and Alzheimer's

A recent Japanese study showed a link between high cholesterol and Alzheimer's disease. The study, published recently in the medical journal of the American Academy of Neurology that people who suffer from high levels of cholesterol face a higher risk of Alzheimer's cases.

Said study author Kinsok Sasaki of the University of Kyushu, Japan "We discovered that increased levels of cholesterol are related to the appearance of large patches of the brain associated with Alzheimer's disease."

In this study, the researchers examined the case of 2587 people aged between 40 to 79 years who do not show symptoms of Alzheimer's disease. They then examined the bodies of 147 people who died after a long period of observation (10 to 15 years). Among them were 50 people diagnosed with dementia before death injury. The search for the existence of snuff spots in the brain and other signs of Alzheimer's disease.

It was found that people who suffer from high cholesterol noon to have the largest cerebral spots compared to persons who have normal levels of cholesterol. About 86% of people who suffer from high cholesterol in their blood stains the brain, compared with 62% of those who have low levels of cholesterol.

In addition to increasing the proportion of cholesterol as a risk factor for Alzheimer's disease researcher found that insulin resistance may represent a risk factor for the last patches of cortex that are associated with Alzheimer's disease.

This study shows clearly the potential impact of increased cholesterol patches on the backs of the brain directly or indirectly, except that the failure of drug treatment for high cholesterol in the treatment of Alzheimer's means there is no link between cholesterol reduction and prevention of Alzheimer's disease.
