Silent strokes erase memory

One in four older people suffering from memory loss, in fact, a victim of the so-called silent stroke. This conclusion was American scientists from the Institute for the Study Taubovskogo Alzheimer's disease and brain aging, as well as the Medical Center at Columbia University.

Researchers examined the health of 658 people from 65 years and older Memory loss Who have not had diagnosed dementia. All of them went through the brain MRI. Then they expect tests, studying memory, vocabulary, speed of information processing and visual perception. It was found that 174 people were silent strokes - small areas of dead cells in the brain.

The study is published in the journal "Neurology." It is reported that the victims with silent strokes on memory tests coped much worse than those who have not been fixed brain damage. This pattern did not depend on the size of the hippocampus - the memory center in the brain.

"Given the fact that severe illnesses such as Alzheimer's disease and other dementias diagnosed solely on the basis of Memory loss Our results can be used as a basis for further studies on the new and more reliable symptoms of these diseases, as well as the development of new methods of prevention, - said in a statement the scientists. - Since silent strokes and the volume of the hippocampus in different ways have been linked to memory loss in our study, the results suggest that the prevention of stroke will be a reliable way to prevent memory problems. "

In other words, based on the set of symptoms such as memory loss , Diagnosis of dementia may not always be true, as scientists believe. And someone mistakenly thought to be a victim of Alzheimer's disease, although in fact he had only just become a victim of silent stroke.
