Alzheimer is a disease that causes problems to the brain. The lack of oxygen and glucose from the blood stream to the brain cells leads o lose its activity, efficiency and eventually die. As engineers, we have looked at the problem in the perspective of engineering side. We have concentrated on the main parameters that play the basic role in keeping the brain cells healthy. Oxygen and glucose are the main sources that keep the brain cell healthy and stay for long time. As a result of the main sources, we have the waste and water back into the capillary. Based on that concept, we've developed our models and used Matlab for the system analysis.
