What happens when our brain fails us? As Dr. Biology, my work has never been involved with diseases that affect the mind, but I do have a personal experience with the shadowy realm of Alzheimer's and other dementias. My mother battled against this relentless adversary and I am not alone. Many people are dealing with loved ones facing one of these diseases. For this episode, I've invited bioinformatics scientist, Kimberly Olney from the Mayo Clinic, to peek into the complexities of the brain and these diseases. This episode is a brief voyage into the brain's amazing and complex pathways and a glimpse of the work being done by dedicated scientists charting a course for a future free from dementia.
