Lisa Genova, a neuroscientist and author of “Still Alice” speaks in this TED talk on Alzheimer’s disease.  Initially a gloomy picture is painted as Lisa highlights the fact that there is still no cure for Alzheimer’s even after decades of research.  However, Lisa eloquently moves from despair to hope as she argues to advocate for proactive approaches to prevent the dreaded illness.  Adequate sleep, cardiovascular health and diet can help prevent Alzheimer’s.
