The disease is progressive destruction of cells and tissues of the brain, especially of those sites, which are responsible for memory and thinking.Experts believe that Alzheimer's disease is associated with the violation of proper protein breakdown in the cell. As a result of accumulated excessive amounts of beta-amyloid protein, whose molecules stick together, as it were, and dying nerve cells. Thin connections between them are destroyed, and they can not transmit nerve impulses, which provide the ability of man to intellectual activity.It is now established that Alzheimer's disease is programmed genetically. If a person has the genes predisposing to the disease, the disease is almost impossible to avoid.The disease usually lasts 5-10 years. Symptoms are usually slow but steady progress....
