Exercise may be key to increase memory retention
Alzheimer's disease is one of the most serious threats to a person's efforts to increase memory retention. The neurodegenerative disorder is extremely common and growing in prevalence. However, a new study suggests that there are some relatively simple things people can do to limit their risk of being affected by the disease.
Researchers from the National Institute of Environmental Science found that exercising on a regular basis can play an important role in supporting the brain health of individuals as they age and prevent the development of Alzheimer's disease.
For the study, the team administered a chemical to mice that is known to kill brain cells. However, mice that got more regular exercise were less likely to experience brain damage during the course of testing. Exercise appeared to cause significant changes to the brain that protected it from harm.
"Exercise allows the brain to rapidly produce chemicals that prevent damaging inflammation," said Jean Harry, who led the study. "This could help us develop a therapeutic approach for early intervention in preventing damage to the brain."
He added that the findings are important because despite tremendous efforts to develop a medication that prevents Alzheimer's disease, there have been few successful trials. The fact that simple physical activity could support the mind could be a major breakthrough.
Author and philosopher Ilchi Lee has long said that individuals need to be mindful of their brain health if they hope to learn how to increase memory power. In addition to physical exercise, he says that individuals should try meditating and other brain-building activities. These approaches could help individuals lead healthier lives free from the shackles of cognitive impairment.

Meditation techniques for stress help individuals channel tension
The problem of stress presents a double-edged sword to individuals studying the brain. On one side, it can motivate people to get things done, while on the other it can hinder a person’s thinking and hold them back. A new study indicates that the degree to which an individual experiences either one of these sides depends largely on their aptitude.
Researchers from the University of Chicago showed that individuals who are more competent students performed better than they normally would when they felt intense stress. However, less capable students buckled under the pressure and failed to achieve a performance that was equal to their already low standards.
"Under stress, we have a variety of bodily reactions; how we interpret these reactions predicts whether we will choke or thrive under pressure," said Sian Beilock, who led the investigation. "If a student interprets their physiological response as a sign they are about to fail, they will. But the same physiological response can also be linked to success if a student's outlook is positive."
The findings underscore the importance of using mediation techniques for stress. This practice can channel a person’s anxiety and discomfort toward more productive responses. Studies have shown that meditation is an effective way to increase memory retention, which may have significant benefits for individuals who are anxious about taking tests.
Ilchi Lee has recommended for years that individuals practice meditation. He says that it is one of the most effective ways to build a high-functioning memory that is capable of peak performance. Meditation may also be helpful when put toward reducing stress and anxiety.

Many people have the wrong idea about ways to increase memory
Human experience is a wonderfully subjective thing that is constantly shifting and changing in the way people perceive it. This is equally true of memory. However, a large percentage of Americans believe that memory is a truly objective and reliable thing, despite mountains of research to the contrary. These mistaken beliefs may interfere with efforts to increase memory retention.
A team of researchers from Union College surveyed more than 1,500 adults from across the U.S. about what they believe when it comes to memory. The results showed that nearly 66 percent said memory was similar to a camera, taking accurate pictures of objective events.
Furthermore, nearly half of respondents said that once they develop a memory, that idea is unlikely to change at any point.
These beliefs are, of course, contrary to a significant amount of scientific evidence. Study after study has shown that memories are plastic and can change over time and in relation to new events. Furthermore, people tend to see more what they want to see rather than any type of objective reality.
"The fallibility of memory is well established in the scientific literature, but mistaken intuitions about memory persist," said Christopher Chabris, who contributed to the survey. "The extent of these misbeliefs helps explain why so many people assume that politicians who may simply be remembering things wrong must be deliberately lying."
The findings may also explain why people have such a difficult time finding ways to increase memory. It may be that they are actually shooting for an objective type of memory that is simply unattainable. Instead, focusing on more practical ways to increase memory may yield better results.
