Researchers from the University of Helsinki have discovered that certain strains of Desulfovibrio bacteria are likely to be the cause of Parkinson's disease in most cases. This discovery could lead to screening carriers of these bacteria and removing them from the gut, which may help prevent the disease. According to Professor Per Saris, only a small percentage of Parkinson's cases are caused by genetic factors, with the majority being caused by environmental exposure to harmful Desulfovibrio bacteria. These findings could lead to the development of targeted measures to remove these strains from the gut, potentially slowing the symptoms of Parkinson's disease. Approximately eight million people worldwide are living with Parkinson's disease.
