These tests are based on scientifically validated cognitive neuroscience methods for assessing attention, memory, and executive functions. These areas were chosen because they measure functions affected by aging and brain disease. The tests were validated in a sample of healthy adults between the ages of 50-79 and normed to include adults in their 40s. Your score is compared to individuals with similar age and education.
