How Older Brains Process Information
Older adults take longer to process information, but that’s apparently no indication of mental acuity, according to recent research. In a matched test, the brains of older people were not as fast as those in a group of younger people, but they performed just as well because their brains are wiser, say Canadian scientists.
When the young participants made a mistake and had to plan and execute a new strategy to get the right answer, various parts of their brains were recruited even before the next task began. However, when the older participants learned that they had made a mistake, these regions were only recruited at the beginning of the next trial, indicating that with age, we decide to make adjustments only when absolutely necessary. The older brain apparently is more impervious to criticism and more confident than the young brain.
According to the Alzheimer’s Association, now is the time to address this looming epidemic that currently has no effective disease-modifying treatments that halt or delay the progression of the disease.
An overall healthy diet also is a proven preventative, according to the Alzheimer’s Association. Research suggests that high cholesterol may contribute to stroke and brain cell damage. And there is growing evidence that a diet rich in dark vegetables and fruits, which contain antioxidants, may help protect brain cells, according to the Alzheimer’s Association.
A mounting body of research also has shown that keeping the brain active is one important part of healthy aging. The Boston Home Instead Senior Care office has a number of resources for family caregivers at www.caregiverstress.com that can help keep seniors healthy and engaged.
