• “The aging brain is subject to a dreary litany of changes. It shrinks, Swiss cheese-like holes grow, connections between neurons become sparser, blood flow and oxygen supply fall. That leads to trouble with short-term memory and rapidly switching attention, among other problems. And that’s in a healthy brain.”
• “But it’s not all doom and gloom. An emerging body of research shows that a surprising array of mental functions hold up well into old age, while others actually get better. Vocabulary improves, as do other verbal abilities such as facility with synonyms and antonyms. Older brains are packed with more so-called …”

We discussed some of these effects with Dr. Elkhonon Goldberg, who wrote his great book The Wisdom Paradox precisely on this point, at The Executive Brain and How our Minds Can Grow Stronger.

In our “Exercising Our Brains” Classes, we typically explain how some areas typically improve as we age, such as self-regulation, emotional functioning and Wisdom (which means moving from Problem solving to Pattern recognition), whereas other typically decline: effortful problem-solving for novel situations, processing speed, memory, attention and mental imagery. 

But the key message is that our actions influence the rate of improvement and/ or decline. Our awareness that “it’s not all doom and gloom” and that there’s much we can do is important. You may want to learn more with our Exercise Your Brain DVD.
