Jill Pease asked a question “I’m going to be running the story on

the ACTIVE findings as the cover story for the next issue of PHHP News, our alumni and donor newsletter. I wanted to do a sidebar that addresses the “what can I do?” question that we seem to get a lot from consumers”

My answer

1. Continue your education.  "Cognitive reserve" refers to the rich network of connections and knowledge that we build across a lifespan. People with more education and more complex jobs generally enter late life at a much higher level of mental functioning. Education can continue: take continuing education courses, read books in areas about which you know little, challenge yourself to learn new things.

My answer

2.  Keep your brain healthy.  "Brain reserve" refers to how much white and grey matter we're able to retain into the later years.  Good health habits that may help to prevent heart attack/stroke, arthritis, cancer, and diabetes also help to maintain the brain:  Aerobic exercise, strength training, good nutrition, control of blood pressure and cholesterol.  It is never too late to begin healthier habits, and exercise training has boosted cognition even in the very old.

My answer

3.  Spot-train your brain.  There is growing evidence that cognitive training, like that used in ACTIVE, can help to improve performance in areas that tend to decline in late life.  Even brief 10 week training programs can produce five-to-ten years of benefit in areas like memory, problem solving, speed, and attention. Excellent, clinically validated training programs are now available at low cost for computers, tablets and smartphones.

My answer

4. Combat negative mood. In general, older adults experience less major depression than younger adults, but depressive symptoms rise. Health challenges, activity restriction due to physical disability, retirement, financial concerns and losing loved ones are among factors that can increase anxiety and depression.  Unfortunately, memory and other areas of mental functioning can be seriously compromised by mood disturbances.  Seeking help with adjustment problems can be a potent way to guard against cognitive loss.

My answer

5. Engage. Participation in complex leisure activities that are new and interesting seems to confer benefits in terms of memory, problem solving, and mood. The benefits seem greatest when these activities are done socially. Tasks as diverse as learning to act, quilt, play piano, use an ipad, or master digital photography have all shown mental or brain activation benefits. Engaging in social leisure seems to have dual benefits: It minimizes negative mood (which can sap mental energy), and it provides a kind of "mental exercise" with complex tasks. The trick, however, seems to be to try something new -- something you've never done before.

Let’s briefly begin with understanding cognitive aging

Many people have a preconception that late life is a time of decline

The story is far more nuanced and individuated.

Dementia is the fear …

…but in fact

The majority of the population will not experience dementia (although rates will grow)

There are, however, significant functional consequences of normal cognitive aging in the absence of dementia that have been largely ignored Medication Finance

Plus prevention

What accounts for cognitive aging? This is a detailed and evolving field,

but at the risk of oversimplifying, there are four BROAD categories of explanation Neuronal/brain loss Reduction in neuronal/brain efficiency Growing interference Disuse atrophy (“sensory underload”,

“disengagement”)

My program of research (and others) In large measure, we’ve tried to chip

away at normal cognitive aging, using the “arsenal”, more or less, as the conceptual framework for guiding our approaches.

In general, the past five years have seen an explosion of research- and market-driven intervention approaches for cognitive aging

Brain health There is an extensive literature

documenting that health issues of later life (especially cardiovascular, and especially hypertension) are destructive to cognitive functioning Especially “executive functioning” Ron Cohen, UF CAM director, and Catherine

Price, CHP faculty member, have been leading contributors to understanding how vascular-related neuronal loss is directly associated with cognitive decline

• No contact control group

• Trained participants improved more than the control participants in executive control functions, such as task switching, working memory, visual short-term memory, and reasoning.
