MemTrax is a short activity designed for measuring memory. By checking their memory, MemTrax allows people to take a proactive approach in caring for their memory health. Treatment can be most effective when it is identified early. The best way to identify early memory loss is to see if memory is changing over time. MemTrax is based on more than three decades of research by renowned psychiatrist Dr. J. Wesson Ashford, to ensure that it provides an accurate measure of memory loss.
