My mother (66yr) is diagnosed with tuberculoma of brain. 3 weeks into treatment, AKT4, streptomycin (0.75), and now she is getting dizzy all the time. Cannot walk without assistance, keeps losing balance. Has lost apetite, eats very little. Confusion of mind is resolved only to a very small extent.
