A study by researchers at Umea University in Sweden, that was published last week in Neurology, shows what is believed to be a connection between depression and Parkinson’s Disease.  Understanding the connection remains a mystery, yet the relationship between the two appears to be solid.  Those study participants with depression were 3.2 times more likely to develop Parkinson’s versus those without depression during the initial year of the study.  As the study progressed, the percentage of those with depression then being diagnosed with Parkinson’s increased with study subjects who started with depression being 50% more likely to be diagnosed with Parkinson’s after 15-25 years in comparison to those without depression. “We saw this link between depression and Parkinson’s disease during over a timespan of more than two decades, so depression may be a very early symptom of Parkinson’s disease or a risk factor for the disease,” said one of the study authors Helena Gustafsson, PhD.
