question: Every once in a while I get these episodes where I get this weird feeling and then if someone is talking to me or if I m watching TV I can t understand what they are saying. It only last like 15-20 seconds and then it s gone. No pain associated with it or anything. I just keep going. I might get 2-3 a month and then nothing for a month or so. I went and had a CAT Scan and they didn t find anything (was worried it was a tumor or something). I tell my doctor the symptoms and he looks puzzled. I m 59 and in good health. Any ideas?
