My 62 husband has been REALLY dizzy, unable to walk without assistance and was told he had a middle ear infection although dr. didn't think ear looked that bad for him to be so dizzy. Four days later he seemed to be worse and returned to dr., same thing but did tests with one being ct scan of brain. It says there are atrophic changes. Chronic ischemic white matter changes. The right mastoid air cells are somewhat hypoplastic as compared to the left. In addition there is some sclerolisis around them, suggesting chronic right mastoiditis with no other abnormalities seen. Explain this please.
