After disappearing for 5 hours one week - a week later, he did tell me he was going for a walk, but again was gone for hours, he wanted to ride the bus with his friend Tim, but got off at the wrong stop. I am not sure how long he was "lost", but he eventually found his friend and rode the bus with him.
At just 62 years old, Rob was diagnosed with Frontotemporal Dementia. He immediately lost his driver's license and his job, since he drove for a living. At the same time, he received a cancer diagnosis, which he has chosen not to treat.
