The common fear of “when will my loved one with dementia forget me?” makes us all question just how our memory works.  We asked Dr. Po-Heng Tsai, a Behavior Neurologist at Banner Alzheimer’s Institute, to help us untangle the issue of time confusion and why people with dementia tend to revert to the past. He explains that memory is not one single entity, but different systems of memory that we have and how the emotional context of memories makes them stronger, causing it to last longer in our brain. Don’t miss his explanation of delirium and how to identify when something else may be going on with our loved one, besides memory issues.
