Could be. This happened to my wife, words were coming out gibberish and she almost fell over. Went to hospital, no sign of stroke . She gets migraines often and they eventually attributed it to a type of migraine or offshoot of it. I forget the terminology. There was a woman reporter on live a few years back and they thought she had a stroke on air, but it was migraine related. The way my wife described it was that she was thinking the words but nothing would come out but gibberish.
