Think of your memory as layers upon layers stacked on top of one another. Registered Nurse Jennifer Crowley specializes in working with patients with Alzheimer’s. Crowley said for people with Alzheimer’s new memories are the top-most layers, and they roll right off and get lost. She conducts Memory Screenings which identify risk for Alzheimer’s and other cognitive impairment disorders. The exam tests short term memory and looks at a person’s understanding of the world around them.
