Are there other causes for tics than Tourette's?

  I have strange movements such as jerking my shoulders, moving my trunk around, rubbing one ankle with the other foot while walking, sudden arm movents, and clumsiness (dropping things, bumping into things, and falling).  
  A neurologist said these were tics.  He thought I might have Wilson's disease.  Tests showed I have excess copper, but not enough to be Wilson's.  Now he thinks I have Tourette's.  I am 55 years old, and these movements started about eight years ago. Since I did not have tics in childhood, can this be true?  Are there other movement disorders which could cause such symptoms?  Thanks for your response.
