Cases of Parkinson’s disease have doubled in the last 25 years, according to figures from the World Health Organization. For decades, the scientists have investigated what triggers this disorder to mitigate its symptoms and anticipate its onset. Parkinson’s disease is a degenerative neurological disorder in which cells that produce dopamine in the brain die, causing symptoms such as tremors, muscle stiffness, slowness of movement, and alterations in balance. In 2017, he led a study that identified for the first time an abnormal form of a protein called SOD1 in Parkinson’s patients. In the second stage, this dose was applied to 10 mice genetically modified to develop Parkinson’s-like symptoms.
