Alzheimer's disease can be cured at the initial stage

November 16 2005

The new tests will treat Alzheimer's disease before its occurrence.

Scientists at UC Berkeley have developed new tests that can detect Alzheimer's disease for several years before a patient of her symptoms.

Scientists presented their findings at the annual meeting of the Society of Neurologists in Washington say that the tests allow them to identify people predisposed to the disease.

Researchers at the University of California at Berkeley for three years was observed in 60 elderly people who were completely healthy. Before the start of the study were made by two pictures of the brain of each. At the same images were reflected area responsible for memory and another - a perception.

Eventually six of their group had developed forms of dementia, and some began to suffer from disorders of perception, which usually precede Alzheimer's disease. When the researchers turned to images of the brain of the participants in the experiment made in advance, they found that in some areas of the brain can be seen prerequisites subsequent disease. For example, the pictures could be seen that the neural activity in the temporal and parietal lobes was below average among those who continue to cope with poor cognitive tests.

Scientists have developed a new test say that the long-standing goal of their work lies in the fact that they have developed tests can be used to create new medicines. We are now developing several drugs that prevent the formation in the brain of protein plaques that cause Alzheimer's disease, but these drugs can be much more effective if applied before the first symptoms of the disease.
