Evidence on Creatine
Strong scientific evidence for this use
Enhanced muscle mass / strength: Several high-quality studies have shown an increase in muscle mass with creatine use. However, some weaker studies have reported mixed results. Overall, the available evidence suggests that creatine does increase lean body mass, strength, and total work. Future studies should include the effect of individual differences such as fitness levels, sex, and age.

Memory Systems as a Shared Resource
This inspired them to depart from testing memory for lists of words and events, and to explore the amount of rich, in-depth information remembered by couples about experienced events. They found these social exchanges led to clear collaborative memory benefits, which could take three forms:
“New information” such as finally snatching an elusive name of a musical thanks to a chain of prompts between the two parties.
Richer, more vivid descriptions of events including sensory information.

1 How Poverty Affects IQ
In a series of experiments, the researchers found that pressing financial concerns had an immediate impact on the ability of low-income individuals to perform on common cognitive and logic tests. On average, a person preoccupied with money problems exhibited a drop in cognitive function similar to a 13-point dip in IQ, or the loss of an entire night's sleep.
But when their concerns were benign, low-income individuals performed competently, at a similar level to people who were well off, said...Fascinating for the fact that IQ appears so plastic in just day-to-day environment. Removing the stressors increases the IQ.
Poverty Impedes Cognitive Function
The poor often behave in less capable ways, which can further perpetuate poverty. We hypothesize that poverty directly impedes cognitive function and present two studies that test this hypothesis. First, we experimentally induced thoughts about finances and found that this reduces cognitive performance among poor but not in well-off participants. Second, we examined the cognitive function of farmers over the planting cycle. We found that the same farmer shows diminished cognitive performance ...The stress of poverty can cause a 13 point reduction in IQ that improves when financial security is attained. Details from this article: "In a series of experiments, the researchers found that pressing financial concerns had an immediate impact on the ability of low-income individuals to perform on common cognitive and logic tests. On average, a person preoccupied with money problems exhibited a drop in cognitive function similar to a 13-point dip in IQ, or the loss of an entire night's sleep."
Reverse Mentoring-Learning
Or want to strengthen your working memory and ability to multitask? Try reverse mentoring—learning with your teenager. This is the first time in history when children are authorities about something important, and the successful ones are pioneers of a new paradigm in thinking. Extensive research shows that people can improve cognitive function and brain efficiency through simple lifestyle changes, such as incorporating memory exercises into their daily routine.

Exercise Rejuvenates the Body
As noted earlier, mitochondrial degradation is a primary culprit in dwindling muscle mass. But recent evidence indicates that exercise can slow down this effect. According to Mark Tarnopolsky, a professor of pediatrics and medicine at McMaster University in Hamilton, Ontario, resistance training activates a muscle stem cell called a satellite cell. In a physiological process known as ‘gene shifting,' these new cells cause the mitochondria to rejuvenate. Tarnopolsky claims that after six month...Strength training specifically prompts the body to produce stem cells that repair motochondria, promotes the production of telomerase to maintain DNA, increase lifespan by six to seven years, and improve cognitive function dramatically as we age.
