Alzheimer’s disease is expected to spike nationwide in future years, and according to new data released by the Alzheimer’s Association, there is a significant shortage in the dementia care workforce. Twenty states in the U.S. have been identified as neurology “deserts” by the Alzheimer’s Association, meaning they had a projected shortage of doctors and caregivers specializing in dementia. Carolyn Berry of Tennessee — one of the 20 “desert” states — says she’s aware of the challenges faced by families of those with cognitive diseases. Berry lost both her grandmother and mother to Alzheimer’s.
