Hypomagnesaemia induced Parkinsonism?

We report an unusual presentation in an elderly woman with a previous diagnosis  of  benign  tremulous  Parkinson’s  disease  who  developed  a  severe Parkinsonian-like  syndrome  with  profound  immobility  following  small  bowel resection.   Her  Parkinsonism  was  largely  unresponsive  to  conventional  medical
therapy.   However, she  was  found  to  be  profoundly  hypomagnesaemic  and  a dramatic improvement in her symptoms and functional ability was achieved after correction of the severe hypomagnesaemia. A brief discussion is included.
