Scientists: humans can fight Alzheimer's disease

The human brain includes compensatory mechanisms in the detection of brain lesions associated with Alzheimer's disease. Scientists give an example: the brain independently finds new resources to support memory and thinking. The mechanisms for this phenomenon is difficult to explain, writes the BBC.

Experts from the University of California conducted a study involving 71 persons without visible abnormalities of the brain. 16 people during a scan was able to identify amyloid deposits are early signs of Alzheimer's disease.

Volunteers have offered to go easy and remember a series of pictures. Throughout the study were recorded brain activity. All volunteers coped well with the exercise, however, people with amyloid deposits were recorded increased brain activity. It turns out that they required more effort to remember the sequence of images. Scientists called this compensatory mechanism of the brain.

Losing the connection between neurons, the nervous system tries to find an alternative. So there are new, less-efficient clusters for thinking and storage of information, experts say.
