Brief Summary:
Subjects are being asked to participate in this study to determine the safety and effectiveness of a drug called atomoxetine in the treatment of freezing of gait for Parkinson's Disease patients. Atomoxetine (ATM) is an approved drug currently on the market for the treatment of attention deficit. It works to increase the amount of norepinephrine (a chemical in the brain that helps keep us awake and alert) in our brain. ATM has not been approved by the Food and Drug Administration (FDA) to be used in the treatment of PD, but has been found to be well tolerated in this patient population.
