The doctors haven't been able to determine if I had a stroke or drug related (symptoms- if the slurred speech, facial palsy, memory problems, problems with working memory, and a 30+ drop in IQ points, weakness right hand). I had an open MRI and nothing was abnormal. They took me off the topamax and there has been no change and put me on verapamil sr. Trust me the verapamil is horrible as cause anxiety, insomnia, increase in appetite and congestive heart failure. At this point, the only thing that the topamax is responsible for was a decrease in appetite ( Yup, I had a stroke). I can't wait to get back on the topamax.
