Early Fitness Predicts Better Memory in Middle-Age

By: Dr. Pascale Michelon

At 50, some people have a better memory than others and experience less cognitive fog. Lifestyle factors may play a role in this variability. Specifically, physical fitness at 25 could predict memory performance in middle-age: the fitter, the better the memory. Continue reading

Physical Activity Boosts Memory, Immediatly

By: Dr. Pascale Michelon

It has become quite clear that physical exercise is an essential part of a brain-healthy lifestyle. Over the long term it helps both preserve the volume of gray matter in the brain and maintain cognitive functions.  A recently published study goes further and shows for the first time that physical activity can have immediate positive effects on memory.

Do you Have a Super Brain?

By: Dr. Pascale Michelon

Is brain aging ineluctable? Maybe not. Researchers have recently identified “SuperAgers,” whose brains at 80+ appear as young as the brains of middle-aged people.
In the study, researchers defined SuperAgers as people over 80 whose memory performance was at least as good as 50- to 65-year-old’s performance.
36 participants of similar education were involved in the study: twelve 80+ SuperAgers, 10 “normally aging” people of the same age and 14 middle-aged.
Using MRI scans it was found that the SuperAgers’ cortex looked very much like the cortex of participants ages 50 to 65. This shows that grey matter loss, although a common part of normal aging, may not be in store for everyone of us.

Bad Fats are Bad for the Brain Too

By: Dr. Pascale Michelon

Fat can be good (e.g., monounsaturated fats) or bad (e.g., saturated fats). How much of which type of fat we ingest can affect our health in general. How about our brain health? A new study has found a link between saturated fats and a decline in memory and overall cognition, and by contrast, a link between monounsaturated fats and better overall cognitive function and memory. Continue reading

How Memory Works

By: Dr. Pascale Michelon

People who complain about their memory lapses often say “I have such a bad memory!” But what memory are they talking about?
Evidence coming from years of research have shown that memory is not a unique system. Our brain contains different types of memory. The first distinction made by researchers is between short- and long-term memory. Continue reading

A Good Night Sleep Boosts Memory

By: Dr. Pascale Michelon

What is the function of sleep? Researchers have shown that memories are replayed and even enhanced as we sleep. In other words, sleeps aids memory consolidation. But how does that work?
One explanation is based on the oscillations in electrical activity that occur naturally during different sleep phases throughout the night. Continue reading

Stress and Memory: What’s the Relationship?

By: Dr. Pascale Michelon

Intuitively, stress does not seem to be a performance booster. We have all fumbled through documents right in the middle of a stressful presentation or conversation, unable to find the document we wanted! On the other hand it feels like a little bit of stress may help arouse us. What does science tell us about the effect of stress on performance? Is stress good for memory? Continue reading
