Massachusetts General Hospital produces a terrific newsletter MIND, MOOD & MEMORY for maintaining mental fitness from middle age and beyond.  In the June issue there are discussions on BIOMARKERS which might show cognitive changes, good news on SENIOR MOMENTS, Q & A with a doctor giving the answers and articles on some of the things that could be linked to mental decline such as poor quality of sleep, anxiety, depression and STRATEGIES FOR A BETTER MEMORY.  The newsletter is just so filled with information.   Subscriptions can be obtained by calling 866 848 2412
