For many people signal the beginning of the early stages are aspects that are not related to memory. For example, the problem with selecting the right words, problems with vision and orientation in space, disturbances in the ability to make decisions and to think logically.
A major risk factor for Alzheimer’s is still considered the age. Today about one-third of people who have reached 85 years may have this disease. Only in the USA it is diagnosed in 5.5 million people over 65 years of age.
Scientists say that the aging population these numbers will continue to grow until we find ways to prevent or delay the development of disease.
