 The patient is a 63-year-old left-handed gentleman who presents for further evaluation of multiple neurological symptoms.  I asked him to discuss each symptom individually as he had a very hard time describing the nature of his problems.  He first mentioned that he has neck pain.  He states that he has had this for at least 15 years.  It is worse with movement.  It has progressed very slowly over the course of 15 years.  It is localized to the base of his neck and is sharp in quality.  He also endorses a history of gait instability.  This has been present for a few years and has been slightly progressively worsening.  He describes that he feels unsteady on his feet and "walks like a duck."  He has fallen about three or four times over the past year and a half.
