Not vitamins: You need to be under the care of a competent neurologist who can first rule out organic disease using history, physical, labs and imaging. It's a shame to have normal pressure hydrocephalus, chronic subdural hematoma, meningeal tuberculosis, lues, or a tumor written off as a "vitamin deficiency" -- that's not how real vitamin deficiencies present. Get with somebody who knows their stuff.
