There are signs of Alzheimer's disease dependent on the size of the hippocampus

With more of the hippocampus (the area of the brain associated with memory) protects a person from the onset of symptoms of dementia, according to U.S. scientists. Scientists conducted a study to examine the signs of dementia in 35 people who died as a result of Alzheimer's disease. It turned out that some of them very silnovyrazhennye symptoms and memory problems were other symptoms almost never on. The researchers found that people who have almost no symptoms manifest or less, about 20% larger area of the brain that had for memory (hippocampus). Scientists warn that even a small study to be carried out, the results may not be quite right. The study was presented at a meeting of scientists in the American Academy of neuralgia. Experts have found that there are often cases in which people died with a diagnosis of Alzheimer's disease and not have any problems with memory and the last day of life. According to experts, the problem should be investigated more deeply, possibly hidden in it an effective method of treating or preventing the disease.
