Memory loss is the familiar headliner, but one of the most insidious symptoms of Alzheimer’s disease is apathy. Not as in a casual indifference or uncaring attitude that might change if you understood more about a thing at hand. For someone with Alzheimer’s, apathy is biological, intrinsic to the disease as it affects the brain’s executive function and diminishes motivation and the capacity to make plans and follow through. It’s as if your brain has gotten the kit for caring and empathy, but with no way to assemble it – the anatomical structures and mechanisms in the brain that would do that are damaged. Apathy is considered the most common neuropsychiatric symptom of those with Alzheimer’s.
