Topamax and senses

I have been experiencing multible side effects loss of speech, word loss, memory loss, twitching of facial muscles around mouth, eyes, nose itching, facial skin feeling like it is moving and crawling. I need people to repeat information to me several times before I get things yet some other senses seem to be improving. I having serious problem with blurring vision I see no one has noted this problem and was wondering if it would go away too or would it do permanent damage? I am not losing weight from taking this medication either but I only take 100mgs afraid of an increase because of the blurred vision.
