I am glad Jason. If I can offer some advise, I have a senior Dad with congestive heart failure that was ok for a few years and then he had "stroke like" symptoms and was rushed to the emergency room. It turns out that because of heart failure, there was insufficent blood pressure to the brain, called ischemia, which looks like a stroke, except that after it happens, the heart beats fast and then they recover after blacking out and convulsing. My father's solution was a pacemaker(overnight operation) to compensate for the insuffiecent heart production and he has not had a "seizure" since. Please ask if this will help your grandpa, it was a miracle in my Dad's recovery. The key word is pacemaker solutions for heart failure. If your grandpa is on blood thinners and blood pressure regulators and has insuffiecent heart production, he could have ischemia at any time, fall down and hurt himself. Talk with the cardioligist. Best Wishes, Phil
