Another study has shown that aerobic activity, such as brisk walking, boosts your brain-actually increasing the size of the hippocampus, a key part of the inner brain involved in forming, storing and processing memory. When compared to an earlier study of cognitively healthy older adults, moreover, the findings suggest that aerobic exercise offers greatest benefits to those who need it most: people with mild cognitive impairment (MCI), often a precursor to Alzheimers disease.
A small clinical trial suggests that green tea could improve the connectivity between parts of the brain involved in tasks of working memory. You might think of working memory as the brains sticky notes, where bits of information are temporarily held for manipulation before forgetting or transferring to long-term memory.
With blueberries and more exotic fruits like aai getting so much press, its easy to overlook the health benefits of the good old strawberry.
Those berries adorning your breakfast cereal or topping your yogurt may be doing more than merely adding fruity flavor to your day
Heres more evidence that eating like a Mediterranean may be good for your brain
Heres more evidence that eating right is good for your brain-and that a diet low in key nutrients and high in unhealthy fats may actually contribute to cognitive decline with aging. Researchers report that older adults with higher blood levels of the B vitamins, vitamins C, D and E and omega-3s scored better on tests of mental performance and showed healthier brains in MRI scans. But older adults with high levels of trans fats, a sign of an unhealthy diet, scored worse on cognitive tests and had lower brain volume.
Tufts new MyPlate for Older Adults helps you plan your plate-and your life. Last year, the federal government retired its longstanding food pyramid, replacing the familiar icon with a new dietary-guidance symbol
I s traffc pollution clouding your brain? Harvard researchers report that a doubling of exposure to black carbon-a marker for pollution from automotive exhaust-was associated with a 30% greater chance of scoring badly on a standard test for dementia. The poorer results, plus lower scores on a composite of six other tests of cognitive function, were the equivalent of adding almost two years to subjects age. Researchers analyzed data on 680 Boston-area men, average age 71, from the VA Normative Aging Study. The in- vestigators said this was the frst study to link traffc-related air pollution and cognition in older men, and only the second study of such a relationship in older adults. Tiny particles in exhaust, researchers suggested, might lodge in the brain, or could cause cardiovascular damage that in turn affects the brain.
