Over the lifetime of the early onset Alzheimer's study, we have recruited hundreds of participants from over 100 different families from Puerto Rico, the Dominican Republic, and the US. Participants are seen several times throughout the course of the study there we conduct follow up visits in addition to their initial visit. Therefore the chart below is divided by newly recruited patients, follow ups, and the total number of patients seen to date. Below you can find our recruitment stats from the most current calendar year (updated on a monthly basis). Below the chart, the recruitment stats from previous years can be downloaded.
