Can We Prevent Complex Diseases Like AD?


Many diseases, such as diabetes, heart disease, and arthritis, are complex. They develop when genetic, environmental, and lifestyle factors interact to cause disease and/or make it worse. The importance of these factors may be different for different people.

AD is one of these complex diseases. It develops over many years and appears to be affected by a number of factors that may increase or decrease a person’s chances of developing the disease. These factors include genetic makeup, environment, life history, and current lifestyle. We can’t control some of these risk factors, but we can control others.
