For the past five decades pharmaceutical drugs like levodopa have been the gold standard for treating Parkinson’s disease. These medications alleviate motor symptoms of the disease, but none of them can cure it. Patients with Parkinson’s continue to lose dopamine neurons critical to the motor control centers of the brain. Eventually the drugs become ineffective and patients’ tremors get worse. They experience a loss of balance and a debilitating stiffness takes over their legs.
