We all have momentary memory lapses. If you’ve ever searched for your lost car in a parking lot, or stumbled for a name mid-conversation, you know that feeling of having an important fact right at the edge of your mind … somewhere. Of course, as we grow older, those temporary memory blips become more troublesome because we tend to wonder if we’re experiencing normal memory problems or bigger issues.
However, it’s important to remember that memory loss doesn’t have to be a normal part of aging. You can take many steps to protect your cognitive health. And no matter what age you are, improving your memory can improve your overall quality of life and health.
A Healthy Memory
Having a healthy, well-functioning memory is vital to your well-being, as well as your sense of identity. Just consider how certain scents can trigger emotional responses and memories. That process–called your olfactory memory–is an important part of the way memory manages our perception of the past and present. In fact, studies have shown that olfactory memories have more power to create a sense of nostalgia than visual memories. On a day to day basis however, smells aren’t that important for memory, but having a sharp mind is.
There Are Ways To Improve Your Memory
If you want to improve your memory, it’s helpful to consider the biology of memory and what can affect it. Memories are stored in your hippocampus, which is considered to be “plastic” because it is constantly changing and influenced by many factors. For example, the neuronal pathways to the hippocampus tend to lessen with age. Hormonal changes can also affect the cells’ ability to regenerate. As a result, many things can affect the functioning of your memory.
Both inflammation and little mini-strokes can negatively affect the memory and even lead to dementia and Alzheimer’s, dreaded conditions we all strongly wish to avoid.
Things That Can Affect Memory Function:
Anxiety
Stress can lead to physical changes in the brain that affect memory function. It’s easy to notice this process in daily life. When you’re overwhelmed, you can feel as if there simply isn’t enough capacity in your brain to take in new information or recall important facts and tasks.
Hormonal Changes
Elevated blood sugars, causing pre-diabetes or diabetes, are very pro-inflammatory. Patients with uncontrolled Type 2 diabetes have a higher risk of developing dementia or Alzheimer’s disease. Ensure your glucose numbers are within normal can be vitally important for long-term memory competence.
Poor Dietary Habits
Your brain needs some healthy fats to thrive—in particular omega-3 oils, high in EPA and DHA. Other foods, such as too much saturated fat and processed, sugary food can impair memory, in part because too they can lead sweet treats can lead to brain inflammation. Also getting in good antioxidants, which help reduce damage in cells, including your brain, by eating vegetables and fruits, is important, too.
Smoking
You can add “poor memory” to the list of reasons to stop smoking. If you’re struggling with this habit (and let’s face it, quitting isn’t easy), talk to a healthcare practitioner.
Germs
Believe it or not, even germ exposure can affect your memory. Scientists have found that exposure to some viruses (in particular, the herpes simplex 1 virus that causes cold sores) can affect memory.
Prescription drugs
Many commonly prescribed drugs can actually harm your memory. Anticholinergics (often prescribed for cold symptoms, incontinence, or allergies) and benzodiazepines (used to treat things like anxiety and insomnia) carry particularly high risk. Statin drugs can cause a type of global amnesia—a sudden, temporary loss of memory that can be very scary. As always, be sure to weigh the potential negative side effects of any medication carefully.
Watching too much television
It’s true: Too many Netflix “binges” can hurt your memory. One study found that watching 3.5 hours of television a day (which is sometimes just a warmup for serious bingers) can negatively affect memory function.
Sleep problems
Recent research suggests that sleep is vital to “consolidating” memories. In other words, our brains aren’t just resting when we’re sleeping, but actually forming and protecting the memories we create during waking moments. When we’re not getting enough sleep, we lose that important processing time.
Thyroid issues
Low levels of thyroid hormone can lead to memory loss and “fuzzy thinking.”
Ways To Help Your Memory
So, how can you help your memory? The list points to potential problems that can be managed. As well, exciting research in neuroscience is pointing to some simple solutions that can help your cognitive health.
1. Practice mindfulness and minimize distractions
Regular meditation can actually alter the physical structure of your brain. Improved blood flow and the creation of more neural connections are some of the paybacks from a regular meditation practice.
However, you also want to make sure your brain isn’t overloaded during the rest of your day. Did you know that we check our phones an average of every 12 minutes? That constant shifting of attention can impact cognitive processes. If you feel uncomfortable when you’re separated from your phone, it may be time for a little soul-searching.
2. Eat for brain health
A great deal of research supports the importance of a healthy diet in protecting brain health. In general, avoid overly processed foods and focus on:
● Leafy greens
● Berries and other antioxidant-rich foods
● Foods high in omega-3 fatty acids, such as salmon, walnuts and chia seeds
● Turmeric (studies have found its anti-inflammatory properties can slow memory loss.)
● Coconut oil (preliminary research points to a protective effect on memory)
3. Move for memory
Exercise helps more than your physical health. It can also boost your cognitive functioning. And it doesn’t take marathon workouts for exercise to have a positive impact on your memory. Even short workouts can boost your recall powers.
4. Train your brain
It’s possible to train your brain to be more efficient. Try some of these simple “hacks” to improve your memory.
- Repeat important information. For example, if you’re introduced to someone, repeat their name back to them. That helps “check in” new facts.
- Play with mnemonics. You may have learned the names of the Great Lakes through the HOMES acronym. Why not create your own acronyms in order to remember lists of items?
- Draw maps. If you have a lot of info to keep track of, try creating a map on a piece of paper. Put the central piece of information in the middle, then draw all of the relevant connections from that point.
- Work with your environment. Don’t hesitate to place little reminders in strategic places. Some people have luck with post-it notes, but they can be more subtle, such as placing a photograph of a loved one who has an approaching birthday beside your bed.
- Press replay. Immediately after an event, replay the important elements in your mind. That will help imprint the things you want to remember.
- Create a memory palace. Try picturing a room that you know very well, and associating each object in the room with an important fact you want to remember.
Note that there are many programs out there that claim to help cognitive health and improve your memory. However, this is an unregulated industry so it’s important to do your due diligence before spending any money. And talking to a medical professional first is always a good idea.
