I am a 63 year old male with balance/gait problems, headaches and tinnitis. Several brain lesions on mri but no clear diagnosis, maybe ischemic strokes they said. Neurologist seemed set it was normal pressure hydrocephelous and scheduled LP. My physio and chiro noticed my eyes did not seem to track correctly. Turns out I had vestibular ocular signal mismatch likely from the areas of ischemic changes in the brain (likely caused by concussions in past sports). My balance and headaches are 85% improved feom simply wearing eyeglasses with corrective prism lenses and doing daily ocular reflex exercises. Sometimes symptoms have unthought of origins. Glad I tried the simple approach. It is life changing.
