headaches??? I'm 27, and I get these headaches where I lose partial vision and can't make sense of anything. People talk to me and I can't answer them in full sentences.  Or I forget how to say the word I'm thinking of.  My hands go numb and I'm very confused and disoriented.  I've noticed that it happens more when I'm stressed out.  But they happen sometimes when I'm driving and I have to pull over untill it fades.  I know it's some kind of migraine, but no one can give me any information.  I've had CAT scans and blood tests just to be told the same thing.... "I don't know what you can do."  My headaches pretty much run my life.  I'll plan to do something and wont be able to because one of these spells will come on.  I've had to quit jobs and cancel functions.  Does anyone else get these kind of headaches or, can anyone give me any info????

Summarized question: What can help with headaches that cause confusion, disorientation and partial vision loss?
