I am dating a guy, age 55, 5 7 very athletic, trail runner, very good shape. Has a type of sezuire, it starts by rubbing his right eye, then stutters, lack of concintration, sometime just seems to be total out of it. will start a converstaion and stop and ask what he is talking about. Actually called and asked me what his phone number was. He has severe sinus infections frequently. The pain he gets in his head is also on the right side, above the ear. He had testing and refuses to tell me what is wrong. I am scared for him. Any help to what the problem is? He lost his mom and dad recently, both in there late 80 s. His mom had alzheimers and dementa,
