Is it possible to mitigate the effects of Parkinson's disease? Neurologist Daniela Berg and her research team in Tübingen are trying to answer that question.They are using a method involving ultrasound to detect the disease in its early stages and pinpoint the loss of nerve cells in parts of the brain. It's hoped that this procedure will enable doctors to use drugs to slow the progression of Parkinson's disease as well, ultimately making it possible to prevent degenerative brain diseases.
