Study unravels how cancer medication works in brains of Parkinson's patients

Laboratory analysis from the first arm of a phase II clinical trial testing the use of nilotinib in patients with Parkinson's disease demonstrates precisely how the agent increases levels of dopamine in the brains of study participants, says a research team at Georgetown University Medical Center. Symptoms of Parkinson's, such as motor dysfunction, are a result of a dopamine loss.
