Have you ever gone to the kitchen or bedroom, only to completely forget what you wanted to do once you’d arrived? Have you ever been unable to find a common word or lost your train of thought, mid-conversation? It’s enough to make you worry you might be losing your mind… and it happens to too many of us after age 50 or even 40...
Yes, it’s happened to me too – so embarrassing and frustrating – and to many of my friends and family. We try to laugh it off as an “old-timer moment” or a “brain fart” although secretly we worry it might be an early sign of serious memory problems. But how would you know? I decided to do some reading to see what I could learn…
Like every part of the body, your brain cells age over the years. Researchers once thought we were born with all the brain cells we would ever have, but in more recent years they’ve realized this isn’t correct. Your brain is “plastic” – it grows and changes with use, creating new nerve cell branches and connections as you make new memories and learn new skills. And new neurons are created too, a process called “neurogenesis”.
“Use it or lose it”
So, the first piece of advice for maintaining a good memory, is to continue to learn throughout your life so you will constantly create new brain nerve cells (called neurons) and new connections between these neurons in your brain. If you aren’t building new connections and reinforcing old ones by using them, the number of connections (and the efficiency of your brain!) will gradually decrease over time. And it’s never too late to start…
The more complex the skill is that you are learning and the less familiar you are with the concept, the better it is for your brain function. For example, learning a new language is highly recommended to keep your overall brain function sharp. I guess I made a good decision when I started learning Spanish several years ago. Trying something that is out of your comfort zone is also recommended, as you will need to work harder at learning – presumably creating more new brain pathways in the effort.
Another approach you could consider, to use and build your brain, is one of the online “brain exercises”. One I came across, MyBrainTrainer.com, is worth looking at, especially if you have frequent memory problems and want an easy way to start rebuilding. It uses a gaming format and compares your scores with their average user, so you can track your improvement. It’s free for the first 3 months to see if you find it useful.
Diet
The second piece of advice I learned, is to look at your diet. While a healthy, balanced diet is recommended to support all parts of the body, fats are needed for healthy brain cells, and specifically omega-3 fats. Nerve cells in the brain have a fatty coating called myelin, that you could think of as “insulation”. When it becomes damaged, the nerve can short-circuit. In Multiple Sclerosis, many nerves lose their myelin protection, and nerve signals to muscles and organs (such as the eyes) can completely fail resulting in inability to move or blindness. In the brain, with its billions of nerve cells, the loss of function of individual neurons is not always so obvious.
Omega-3 fats are found in seafood but be aware that some fish contain methyl mercury which can harm your memory, especially large lazy fish like tuna (albacore and ahi tuna), swordfish and shark, that eat smaller fish, concentrating the mercury or those caught in lakes that contain large amounts of run-off surface water (the Great Lakes, for example). Salmon, shrimp, tilapia, canned light tuna and catfish are said to generally have lower mercury levels. And little fish like sardines, anchovies, and scallops tend to be low, being lower in the food chain that concentrates mercury. An omega-3 supplement that has been tested for methyl mercury content might be a good choice to increase your intake, unless you can verify the mercury content of the seafood you purchase.
The main fuel for your brain is glucose, so eating complex carbohydrates is thought to be helpful for memory. These foods – whole grains, beans, peas and vegetables – release their glucose more slowly, keeping your brain supplied with its favourite fuel much longer than simple sugary foods do.
You also want to avoid “brain rust”, oxidation damage to your brain cells. Oxidation is a natural process: oxygen radicals, that are produced as a by-product of our metabolism, cause damage to healthy cells. As we age, we become less efficient at repairing the damage they cause. Eating anti-oxidant foods can help prevent as much damage from occurring. Colourful fruits and vegetables contain lots of antioxidants, hence the recommendation to serve a colourful plate. But other foods can contain high levels of antioxidants too. These include onions, artichokes and russet potatoes; green and black tea; red wine, grape juice, and pomegranate juice; nuts, such as peanuts with their skin, almonds and pecans; and spices, such as cinnamon and turmeric. It’s been reported that in India, where the average diet contains plenty of turmeric-containing curry and seafood, the occurrence of Alzheimer’s disease is one-quarter of the rate in North America.
I have more to say about helping your memory, but it’s August and I know there are too many things to do outside to spend time reading a long article… So, I’ll continue this topic next week with other information I learned about how to keep your brain at its best!
