WORLD Radio’s Jenny Rough was worried. Last year, her memory seemed to be slipping, and few things scared her more than descending into dementia as she got older. She also came across some recent research that tied dementia and Alzheimer's disease to a person’s ability to navigate–and Jenny has always had a little trouble with maps. Worst of all, her own mother had passed away from Parkinson’s disease a few years before.So, naturally, Jenny went for a good long hike … and got lost.On this episode of Doubletake we’re going to navigate—metaphorically and literally. We’ll explore the pathways of the human brain, hike trails in the Rocky Mountains, and journey along the road of grief.Support WORLD News Group at wng.org/donate (http://wng.org/donate).
