NOTE FROM TED: While some viewers might find this talk helpful as a complementary approach, please do not look to this talk for medical advice. The role of lifestyle in disease remains an ongoing field of study. TEDx events are independently organized by volunteers. The guidelines we give TEDx organizers are described in more detail here: Alzheimer’s disease currently affects over 44 million worldwide and has no cure nor effective treatment. For most people over the age of 60, this disease represents their number one fear. But we don’t have to be afraid of Alzheimer’s. By better understanding our genetic risks, and defending ourselves against it with a variety of common sense, everyday activities, we can increase the odds of overcoming this devastating disease. Troy Rohn has been a professor in the Department of Biological Sciences for the past 20 years where he both teaches and has an active research program involving Alzheimer's disease. For the past 10 years, his research program has focused on understanding how inheritance of the APOE4 gene enhances dementia risk at the molecular level. This talk was given at a TEDx event using the TED conference format but independently organized by a local community. Learn more at
