I had gamma knife in March of 2012. I never had balance issues until after the GK! I am going through a bout of vertigo right now in which the room spins every time I move my head. Doc rx'd a dose of steroids but they had no effect on my symptoms. They are confused because both my post-GK MRI's showed some slight shrinking of the AN. My first bout of dizziness occurred last December, some 8 months after the GK. I am getting very discouraged by this. Some on line searching led me to a disorder called Endolymphatic Hydrops. Primary endo. hydrops is known as Meniere's Disease but secondary appears to occur in response to an event or underlying condition such as head trauma or ear surgery. (hello!) I know that AN has nothing to do with the endolymph (the fluid w/in the endolymphatic sac, a compartment of the inner ear). However, it is possible that this separate condition could be brought on by the AN and its treatment. Treatment is through vestibular therapy and diet. I have an appt with my neuro next Tuesday and I plan to discuss this possible diagnosis with him.
