"The hallmarks of bvFTD are personality changes, apathy, and a progressive decline in socially appropriate behavior, judgment, self-control, and empathy. Unlike in Alzheimer’s disease, memory is usually relatively spared in bvFTD. People with bvFTD typically do not recognize the changes in their own behavior, or exhibit awareness or concern for the effect their behavior has on the people around them."
