People as Young as 25 Could be Screened for Dementia

dementia

There is a possible connection between the energy-producing process in young adults and the later development of Alzheimer’s.

People as young as 25 could be screened and treated for dementia years before any symptoms develop after Alzheimer’s disease was linked to the way the brain uses sugar to make energy. Proteins called amyloid plaques which build up in the brain of dementia sufferers are thought to be linked to the onset of symptoms such as memory loss and mental impairment.

Educated People Better Able to Cope with Effects of Dementia

Just one extra year of education can cut the risk of developing dementia.

Educated people are better able to cope with the physical effects of dementia, and even one extra year of education can significantly cut the risk of developing the brain-wasting disease, scientists said on Monday.

Study Finds Big Hips ‘Impair’ Women’s Memory

Body Shape Can Indicate Quality Of Memory Function

A woman’s body shape may influence how good her memory is, according to US researchers. Although carrying excess weight anywhere appears to impair older women’s brains, carrying it on the hips may make matters worse, they say. The Northwestern Medicine team found “apple-shaped” women fared better than “pears” on cognitive tests. But depositing fat around the waist increases the risk of cancer, diabetes and heart disease, experts warn. They said the findings, in the Journal of the American Geriatrics Society, highlighted the importance of maintaining a healthy weight for both body and mind.

Some of the health risks associated with obesity, such as vascular disease and inflammation, may explain why people who are overweight appear to be at higher risk of dementia…

What is the Maximum Memory Capacity of the Human Brain?

BRAIN POWER!!!

Paul Reber, professor of psychology at Northwestern University, responded to this question submitted to Scientific American:

The human brain consists of about one billion neurons. Each neuron forms about 1,000 connections to other neurons, amounting to more than a trillion connections. If each neuron could only help store a single memory, running out of space would be a problem. You might have only a few gigabytes of storage space, similar to the space in an iPod or a USB flash drive. Yet neurons combine so that each one helps with many memories at a time, exponentially increasing the brain’s memory storage capacity to something closer to around 2.5 petabytes (or a million gigabytes).

Scientists Say People Learn More After A Siesta

Shut eye equals brain power
Curling up for an afternoon nap can improve the brain’s ability to learn by clearing out cluttered memory space, psychologists say.

People who nodded off for an hour after lunch performed better in learning tests than those who stayed awake all afternoon, the scientists found.

Magnesium Supplement Helps Boost Brainpower

Increasing magnesium intake may be a valid strategy to enhance cognitive abilities.

New research finds that an increase in brain magnesium improves learning and memory in young and old rats. The study, published in the January 28th issue of the journal Neuron, suggests that increasing magnesium intake may be a valid strategy to enhance cognitive abilities and supports speculation that inadequate levels of magnesium impair cognitive function, leading to faster deterioration of memory in aging humans.

Taking A Break After Learning Something Helps You Remember It

Taking a coffee break aids memory

Scientists have always known that sleeping helps consolidate memory by allowing your mind to sift through recently gained knowledge and file it in the brain.   But this new research suggests that even a short rest or break while conscious could help it sort and retain information.
