Phosphatidylserine (PS) and Age-Related Cognitive Decline (ARCD)

1. Age-Related Cognitive Decline (ARCD) Age related cognitive decline (ARCD) [1] is the scientific term for memory loss in elderly people who are clinically healthy. It is a physiological process associated with aging, not a disease, and occurs during middle life or later. Many people who are clinically healthy find as they get into their forties or fifties, sometimes even as early as their thirties, that they are losing mental sharpness. They have more trouble to keep track of their glasses and their keys. They have increasing difficulties in remembering names and matching names to faces. After reading important material, they forget it within minutes. One estimates that more than 40 percent of people aged 50 to 59 show ARCD, as do more than 50 percent of people aged 60 to 69, and even a greater proportion of those past 80. The decline in memory is significant, approximately half of our memory capabilities at age 25 are lost at ages 50-59, and even up to three quarters at age 70+.
