Is there a way to distinguish age-related cognitive impairment from early Alzheimer’s disease?
Though there are other technologically advanced methods available, the best way to make a diagnosis of Alzheimer’s disease is to conduct a battery of neuropsychological tests. They can take several hours to administer, but they are the most sensitive way for physicians to diagnosis the condition. While it is known that Alzheimer’s disease is associated with aging, it is also known that it is possible to live to 120 years of age and still be cognitively intact. Therefore, distinguishing age-associated cognitive impairment from early Alzheimer’s disease may be slightly artificial beyond that age. Since we know that it is possible to live to ≥100 years of age with completely intact cognition, we have taken that as our working definition of “successful aging,” and that is our goal.
