A Cambridge University study suggested that jogging just a couple of times a week stimulates the brain. After a few days of running, hundreds of thousands of new brain cells were shown to have grown in a region that is linked to the formation and recollection of memories.
An improved ability to recall memories without confusing them has a direct impact on other crucial cognitive tasks, and could lead to potential new ways of slowing down the deterioration of mental ability in old age.
The protein acts as with another protein, bone morphogenetic protein, and stimulates the division of brain stem cells, keeping the brain nimble and active as we get older. Research suggests that amplified production of noggin could therefore prevent the on-set of age-related brain diseases such as Alzheimer's.
A Mid-Day Nap
Scientists have long suspected that sleep has a significant impact on the brain's capacity for memory, but recent research has found that sleeping for an hour in the afternoon boosts brain power and dramatically increases its ability to learn new facts and tasks.
Having a nap after lunch acts as a regenerative aid, allowing the brain to 'file' away memories so that new information may be more easily retained.
The researchers discovered that those who stay awake all day are less likely to be able to learn new tasks as the day goes on, leading the experts to suggest that napping in the long-term may be conducive to warding off age-related degenerative mental diseases.
Magnesium and Vitamin B-Rich Foods
Other research found that high doses of B vitamins halved the rate of brain shrinkage in older people experiencing signs of memory decline. Certain B vitamins, including folic acid, vitamin B6 and B12 - were also found to control levels of a substance known as homocysteine in the blood. High levels of homocysteine are associated with faster brain shrinkage and Alzheimer's disease.
Another study published in the Journal of Neurology found that an association between increased vitamin D and faster information processing was particularly significant in men over the age of 60 years.
Mowing the Lawn
Researchers have discovered that a chemical released by lawn mowing not only relieves stress and makes people happier, but could also prevent mental decline in old age.
Australian scientists claimed that the aroma of freshly cut grass works directly on the brain, particularly targeting areas associated with emotion and memory. These are known as the amygdala and the hippocampus and are the two areas that are responsible for the flight or fight response and the endocrine system, which controls the releasing of stress hormones like corticosteroids.
Chronic stress has been shown to damage the hippocampus (an area of the brain that helps regulate emotion and memory), by reducing the number of connections between communicating cells, leading to memory loss, sometimes irreversible.
