How To Treat Viral Neuritis?

Hi, I am a seventy year old female and am anticipating retiring from teaching next month. I have a very active live, but in January had a severe episode of viral neuritis. This has caused me to lose my sense of balance and I am working to restore it. While I was in the hospital I was given an MRI. The findings were: No difusion abnormality is noted. Ventricles and slci appear normal for patient's age. Mild periventricular white matter hyperintensities are noted and most like represent chronic deep white matter ischemic changes. No mass, mass effect or midline shift is noted. No evidence of intracranial hemorrhage is noted. Midbrain, pons and medulla and cerebellum appear unremarkable. Intracranial internal cartoid arteries are ilaterally ectactic. No aneurysmal dilatation, however, is noted focally. Symmetrically increased signal of bilateral globus pallidus is only seen in T2 sequences and may represent physiologic changes. Brainstem appears unremarkable.
Corpus callosum appears intact. Pituitary gland appears normal.
