I am new to this listservice. My mother-in-law has Parkinson's Disease and is in the later stages. I am interested in finding out how many people are diagnosed with Parkinson's each year in the United States i.e. incidence rate. I am an epidemiology doctoral student and am trying to get a grasp on the enormity of the problem. Could you help me.
