OK. Did she think neurologically you were stable? EEG done recently? My first AED was dilating and I had tremors. Then I was switched to topiramate 400mg daily had tremors . I was on clonazpam top at the time and an eeg showed encephalopathy from the dilating and clonazepam. My doctor at the time refused to reduce dosages so I found another neuro who did. Under her I was switched to topiramate tapered off clonazepam and then topiramate dosage lowered to 150mg daily. My tremors disappeared my memory executive functioning critical thinking improved rapidly. What about dose reduction in the lexapro trying meditation tai chi? Life style changes that help you?
