We all know the feeling.
You’ve lost your keys. You’re SURE you put them on the table by the door as usual, but they’re not there. You search and search, becoming more frustrated by the minute when suddenly you find them in your pocket or on the kitchen table. How could you have forgotten putting them there? Are you losing your mind? Could it be dementia or an early indicator of Alzheimer’s disease?
Chances are, it’s nothing serious. So many things can affect memory, including stress, distractions, and an alteration in routine. And yes, age.
Brain scientists believe that the effects of normal aging on memory may result from subtle changes within our brains. So, to understand how aging affects memory, we need to look at natural changes in the brain as well as how we store memories.
HOW AGING AFFECTS MEMORY
With aging, our brains lose cells in areas that produce important neurotransmitters (chemicals that carry information between neurons). The decrease in the number of these cells and their ability to make the
enzymes necessary for good memory function upsets the delicate balance of these chemical messengers.
Other changes occur in the brain’s white matter. This part of the brain contains nerve cell fibers….the “telephone cables” of the brain …through which communication with other cells takes place. How these changes affect memory is not entirely clear, but it may be that they make cell-to-cell communication less efficient.
STORING NEW MEMORIES
As we get older, our ability to create new memories may also be affected, making it more difficult to learn new things. It’s not that we forget more easily; we may simply take longer to learn information in the first place.
In practical terms, this means as we get older we may have to pay closer attention to new information which we wish to retain. We may also need to try different strategies to improve learning and trigger memories.
Once the information is learned, however, it is retained equally well in all age groups, even though older people may need a bit more time to learn it and perhaps to retrieve it. A substantial number of 80-year-olds perform as well as people in their 30’s on difficult memory tests.
OTHER ISSUES
Don’t always jump to the conclusion if you can’t remember something, you may be slipping mentally. Forgetting may actually be almost as important as remembering. Retaining every single bit of information you’ve been exposed to throughout your life would be disastrous. For this reason, your brain sorts out what will and won’t become long-term memory depending on your needs.
How this happens is a matter of continuing debate among researches, however, it’s generally accepted that memory function is influenced by factors such as:
emotional state
stress level
environment
previous memory
biases
perceptions
WHAT YOU CAN DO
Continuing to learn new things throughout your life can help keep your brain healthy and your memory sharp. Read, learn a new language, learn a new card game, learn a skill that combines brain function with manual dexterity like knitting or wood-working. All these things are exercise for the brain and will help you keep your memory.
Stay involved and engaged with friends and in the community. Make sure you have a reason to get up in the morning and a goal to achieve every day. The rocking chair may be a popular retirement image, but it’s bad news for memory and brain function.
Stay physically active. Walking, swimming, dancing or anything else that gets your heart rate and respiration up a bit (within safe parameters according to your doctor’s guidance) keeps your blood flowing and your brain oxygenated.
Eat a healthy diet devoid of too many sweets and artificial flavors and sweeteners which can cause fuzzy thinking and lethargy. Fresh vegetables, fish, nuts, low fat quality proteins and lots of water are all good brain foods. Avoid excessive alcohol consumption and tobacco.
Don’t hesitate to check with your doctor if you believe your memory is slipping. Catching medical problems like diabetes and vascular problems early on can help you avoid dementia later on in life. In addition, many often-prescribed medications can cause fuzzy thinking and memory problems, so talk to your doctor if you think that may be the case with you. A simple adjustment in dosage or formulation can make all the difference in the world.
WISDOM
Also, realize as you get older you know more and can understand how to use what you know in the best and most efficient ways. In other words, as you get older…you get better at selective memory.
That’s called WISDOM and it can serve you well.
