Previous studies have found links between depression and Parkinson’s disease, but few have examined whether a link exists between bipolar disorder and Parkinson’s.
Recently, however, lead study author Mu-Hong Chen and collagues — from Taipei Veterans General Hospital in Taiwan — decided to investigate.
They have now published their findings in the journal Neurology.
In Parkinson’s, neurons in certain parts of the brain gradually die, which results in symptoms that include tremor, rigidity, slower movement, and difficulties in balancing, swallowing, and speaking.
