“Our study showed that six months’ worth of vigorous exercise may pump blood to regions of the brain that specifically improve your verbal skills as well as memory and mental sharpness,” said neuroscientist Marc Poulin.
The study found that after only three months of high-intensity workouts several times a week, older adults tended to score about a third higher on a memory test.
What many people are really recalling is “an episodic-memory-like mental representation consisting of remembered fragments of early experience and some facts or knowledge about their own infancy/childhood,” write the authors of the study.
A large majority of the adults who were polled said they take supplements or solve puzzles to keep their brains healthy — two strategies that have not been shown to be effective at enhancing memory or warding off dementia.
“This will surprise many people as it contradicts our intuitive understanding,” said Rob Jenkins, a psychologist at the University of York.
Higher levels of cortisol were also associated with less volume in certain areas of the brain. Cortisol’s production in the body increases in response to stress.
A recent study found that when people take photographs they tend to remember less about the experience than when they keep their camera tucked away.
“The thing that seniors in particular should be concerned about is, if I can get very good at crossword puzzles, is that going to help me remember where my keys are? And the answer is probably no.”
With the results of the new studies, “the hopes for testosterone-led rejuvenation for older men are dimmed and disappointed if not yet finally dashed,” writes endocrinologist David Handelsman.
The theory is that sleep reinforces negative memories in the brain. So if disturbing thoughts are on your mind when you drift off to sleep, you may have more difficulty suppressing them later.
Men tend to be better than women at remembering details from action flicks, while women tend to surpass men at recalling the finer points of romantic comedies, a new study suggests.
The warning sign — forgetting that you have forgotten — starts to occur two to three years before the onset of dementia, the findings also indicate.
Still, “There is clear evidence that physical activity and a healthy diet contribute to improvements in a wide variety of health outcomes,” a JAMA editorial says.
“Many of us can relate to the idea that people have different abilities when remembering events. What is unique about these individuals is that they have no personal recollection,” said Brian Levine, the paper’s senior author.
A new study offers more evidence that our memories — even for extremely common images — are much poorer that we believe them to be.
After naming the first three or four U.S. presidents, people had trouble recalling the names of presidents in the order they’d served.
“Sustaining repeated head impacts during a critical neurodevelopmental period may increase the risk of later-life cognitive impairment,” the authors conclude.
A new study takes a closer look at why and when our earliest memories vanish.
The authors of the study believe its findings suggest that caffeine helps with a deeper level of memory known as pattern separation.
The study consisted of two related experiments. Both took place at Fairfield University’s Bellarmine Museum of Art.
