Every time NFL wide receiver Terrell Owens steps onto the football field, his mind turns to the woman he credits with getting him there: his grandmother. She took him in when he was a young boy and raised him. What breaks his heart is that she will never know how far he's come.
Alice Black was diagnosed with Alzheimer's disease 14 years ago, during Owens' first NFL season. Now, she no longer knows her grandson. "The disease has robbed her of her memories," says Owens, who plays for the Cincinnati...
Mental engagement is consistently linked with a decreased risk of a decline in thinking skills. So games, puzzles, and other types of brain training may help slow memory loss and mental decline.
Here are answers to some commonly asked questions about the impact of brain exercises on memory and dementia.
Can brain exercises prevent memory loss or dementia?
Researchers still need to do more study. But there appears to be a consistent link between brain training and a decreased risk of mental decline.
Some studies have shown brain training can have long-lasting positive effects. That was seen, for example, in a study called ACTIVE -- the Advanced Cognitive Training for Independent and Vital Elderly study.
The study involved 2,802 adults aged 65 and older. Participants attended up to 10 brain-training sessions over a 5- to 6-week period. The sessions included training in strategies for:
Speed of processing information
People who took the training showed improvements in those areas that lasted for at least 5 years. Even better? This translated into improvements in their everyday lives, such as the ability to manage money and do housework.
But what about prevention of Alzheimer's and other dementias? Does brain training help? A study published in 2010 looked at this very question.
It found that staying mentally active delayed cognitive (thinking) decline. After onset of Alzheimer's, however, mental decline sped up in people who were mentally active. How could this be true? It's possible that being cognitively active initially bolstered the brain, so symptoms didn't show up until later in the disease process after it reached a kind of tipping point.
The silver lining here? People who are mentally active may spend a shorter part of their lives in a state of decline, even if they develop Alzheimer's.
How does brain activity help?
Animal studies have shown that mental stimulation may help protect the brain by:
Decreasing the hallmarks of Alzheimer's, such as increases in certain proteins (plaques and tangles)
