It provides a method of drug prevention of dementia

American scientists have found how to deliver medication directly into the brain in order to prevent construction there beta-amyloid plaques, causing Alzheimer's disease. Thus, to create a truly effective means of prevention of yet incurable disease.

Alzheimer's disease

Weekly injections capable prevent Alzheimer . It became possible after American scientists in the company Genetech San Francisco discovered how to deliver drugs to the brain. Treatment neurological disorders such as dementia, always proved difficult because the brain is a network of blood vessels known as a barrier between the blood and the brain (blood brain barrier), which It stops all the necessary nutrients and drugs and does not allow they get inside.

American scientists have for the first time the history of science were able to overcome this barrier by attaching antibodies to special protein called transferrin, which occurs in the body human. This helped to transport drugs directly in the brain. Once inside the brain, the antibody blocked the building of toxic Beta-amyloid plaques that are harmful to the neurons of the brain and cause Alzheimer's disease .

Tests on monkeys showed that a single injection of antibodies can prevent Construction plaques without any side effects for up to a week and Intravenous injection provides the effect of a whole month. Currently a group of scientists is planning to conduct the first test of his technique on humans. Alzheimer's disease is the most common form of dementia, from who suffers more than one million people in Russia. All currently available drugs not able in any way to influence the course of illness.
