2	The BAD News: Memory decline begins as early as age 30 Loss in function due to aging brain machinery Processing speeds slows Loss of speech comprehension
3	The GOOD News The Brain is PLASTIC Able to generate brain cells Able to reorganize itself … at any age! (This is a relatively recent discovery.)
4	The BIG problem As we age, we get stuck in the same routine. Our brain needs to LEARN NEW THINGS to stay healthy.
5	Older folks tend to … not challenge themselves only do activities they are really good at not be active physically
6	Scientific Research indicates … You can slow or even reverse brain decline through: Diet Exercise Brain calisthentics (“neurobics”)
7	The Effect of Diet Best bet is fish (omega-3 fatty acids) Doctors recommend fish 2 or more times/wk. Sardines are good brain food. 60% less risk of Alzheimer’s 10% better (slower decline) on memory tests
8	The Effect of Exercise Physical exercise helps keep your brain in shape. Increases blood circulation and oxygen to brain Promotes growth of new brain cells Studies show people who walk regularly show improvement in memory and learning ability (and cuts stroke risk) Even a little is good, but more is better
9	Brain Calisthenics To stay healthy, your brain needs: to LEARN something new to CONCENTRATE To use input from all your senses
10	“Brain-training” programs have … Enhanced cognitive function Improved memory Improved control of movements
11	“Neurobics” is the latest trend With video games Software Websites All aimed at exercising the brain!
12	Some great brain exercises Learn to play a musical instrument Learn how to use a computer Learn a new language Do crossword puzzles Memorize poetry Take a course in something you know nothing about Learn to play chess
13	More exercise … Work jigsaw puzzles Brush your teeth with your “other” hand Identify a pile of coins by feel Learn and use a new word everyday Learn how to play bridge (card game) Take a course in logic Take the emergency medical training
14	The Future Drugs No perfect “brain” drug yet, but … scientist are working on it Cognitive enhancers Modafinil: can keep you awake and alert for 90 hrs straight with no jitters or bad concentration Other new drugs to improve memory without side effects Ampakines: makes an older person perform mentally like a much younger person
15	Technology Brain transplant? Yes, maybe! At USC, computer chip implanted to replace part of a brain (in a rat) 2006 experiment: inserted nanotechnology fibers into a blind hamster’s brain and brain was able to reconnect and restore sight.
