Q

Another new patient presents today (your practice is booming… that always happens before you go on vacation..) with a gra onset of sensory losses, weakness, ataxia, and fatigue. She is 31 years old and has not seen anyone else for these symptoms do a neurological exam and find that she has vibratory loss in the toes on both feet, not following any dermatomal pattern. Y also do some cerebellar tests, and find that she has intention tremor, especially at the terminal ends of the motion. You order blood work for antinuclear antibodies and an MRI. The blood work is positive for anti-myelin basic protein antibodies, and th shows plaquing in various white matter areas. What is your diagnosis?
