A Study to Evaluate SYN120's Safety, Tolerability and Efficacy in Parkinson's Disease Dementia

What we are studying

The purpose of this research study is to find out if SYN120 can be safely given to patients with Parkinson’s disease dementia (PDD) already treated with a stable dose of a cholinesterase inhibitor (i.e. Aricept, Exelon, Cognex, Razadyne, or Namzaric) and to see if SYN120 helps to improve cognition (also known as your ability to think, understand, learn, and recall). We also want to find out if SYN120 can improve your ability to remember past personal events (also known as episodic memory).
