Towards targeted treatments

According to researchers, this is the first time that such a link is clearly established. These results are based on the analysis of eighty studies published in the past fifty years. “These conclusions represent a major advance in the study of non -motor symptoms of the disease”explains Julie Péron. associate professor at the Unige neuropsychology laboratory.

Geneva researchers argue that these results are systematically taken into account during the diagnostic and support Parkinson’s disease. This would help orient patients towards more suitable treatments, depending on the type of parkinson which they are affected.
