I took away three things from his presentation. First it's an inflammatory disease very sensitive to sugar intake. Second, sleep is an important part of daily brain maintenance. Third, life-long learning creates new synaptic connections to offset the ones destroyed by the disease mechanism. So that's become my three-part prevention plan: reduce sugar intake, get enough sleep and stay intellectually active. There are no guarantees, but these are choices available to me. Then, after he finished his talk, we all filed out of the meeting for the morning break and decimated all the muffins and coffee available.
