This is our third in series of columns on brain health, this month we will explore memory.  It goes without saying that memory is a vital human process, for example social interactions would be limited if you couldn’t recall who your family members are, plus it would make Thanksgiving awkward.  We use memory for problem solving, like answering test questions or assembling Ikea furniture.  It keeps us safe through planning and navigating familiar and unfamiliar places and avoiding things that previously harmed us.  In a large sense we are our memory, and our memory is us.

There are three types of memory:

1. Sensory memory, or sensory register, is a quick (0.2 – 2 seconds) collection of information from our senses. Once the information collection is complete it moves to either your short-term memory or other parts of the brain for memory storage. Those memories are brief. Our capacity for sensory memory is huge, because we are usually using multiple senses at the same time. Sensory memory ensures we are aware of what we are immediately experiencing, it helps keep us safe and at the same time enjoy the world around us. Some examples of sensory memories are:

• The melody of a song continuing after the song has finished playing
• Continuing to feel the touch of someone after they let go of your hand
• The taste of food after you have finished eating
• Seeing the colors of fireworks after they have faded
• Continuing to smell bread after walking out of a bakery

2. Short term memory https://www.ncbi.nlm.nih.gov/books/NBK545136/ , or active memory, temporarily holds information from seconds to minutes and this information is (supposedly) easily accessible. While sensory memory stores experiences, short term memory stores information you have learned. Short term memory receives and process sensory information and converts short term memories into long term memories. On a good day you can hold five to seven items in your short-term memory, like a phone number or a license plate number, for about 15 to 30 seconds.  After that the information is moved to your long-term memory.  However, there is a difference between working memory and short-term memory.  Working memory is temporary story of information you can change, or manipulate to help with reasoning, learning and understanding while short term memory is a temporary storage space of unchangeable information, not unlike a sticky note.  Short term memory is an essential part of your cognitive functioning.  It may be temporary storage, but it has an important role.  For instance, by the time you finish reading this sentence, your short-term memory has already removed the previous sentence from its temporary storage space to make room for this sentence.
3. Long term memory https://www.ncbi.nlm.nih.gov/books/NBK549791/ is a nearly permanent storage space for learned information and experiences. The main function of long-term memory is to be an archive – to make short term memories more permanent. There are two main types of long-term memory:

• Explicit memory is the storage of facts, events, and locations. You are always adding to this storage space and recalling this information as needed.
• Implicit memory is the storage of learned skills, habits and relationships. You are not consciously aware of when you are learning this information, but you can recall it at any time.

Together these two areas (and their multiple subareas) allow us to learn and perform tasks, relate to past experiences, make connections, adjust to our environment, and recall how to tie your shoes and turn on your phone – along with a yet-to-be fully understood multitude of other functions and processes.  An astounding number of memories last years or decades and some a lifetime.

We have previously discussed things can affect all three memory types such as poor blood flow but other conditions impact memory as well such as traumatic physical injuries, acute and chronic disease, and psychological/emotional trauma https://www.nia.nih.gov/health/memory-loss-and-forgetfulness/memory-problems-forgetfulness-and-aging .

How can we exercise our memory? Every activity listed above is a memory exercise, and we can also add the following:

• Focus – be aware where you set your car keys or phone down. Reduce distractions (both internal and external), the object is to seamlessly move information from sensory to short term to long term memory.
• If you don’t already, start journaling – on paper using a pen. If you already journal, make it a daily practice.
• Put puzzles and Lego projects together – activities requiring you to remember instructions/sequences and placements.
• Play memory games such as Sudoku, do a daily online cross word, play online word games such as Wordle, Strands and Letter Boxed.
• Play chess, checkers, even video games.
• Memorize your shopping list, begin by memorizing five items then work your way up.
• Become and stay organized in your home – make a happy place for everything.
• Stay physically active, exercise regularly – at least three days a week for an hour or more.
• Learn new skills – a new language or musical instrument.
• Listen to complex music (to suit your taste) such as classical and jazz.
• Learn new physical activities – dance, Taichi, yoga, pickleball, martial arts.
• Stay social, which has different meanings in these modern times, and stay connected to others.
• Read books, the kind made of paper.
• Improve you sleep patterns and sleep time – we could do an entire series on this subject alone – but research, explore and experiment with new ways to help you sleep.
• If you don’t already, meditate daily. If you don’t meditate or haven’t in a while explore the numerous apps out there to help you ease into a daily practice.
• Take your medications as prescribed and explore all available resources to help manage chronic health conditions.

We are continuing our exploration of brain health this month by looking at cognition and how we may be able to improve our cognitive abilities in daily life.

Cognition collectively means the processes taking place in the brain, including thinking, attention, language, learning, memory and perception – in other words, everything that connects us to the world and the world to us. When we experience a change in cognition, we also experience a change in self and in how we perceive the world. I think we agree anything we can do to maintain and, perhaps, improve cognition is in our favor.  But before we enter that discussion let’s look at some of the things that can affect cognition.

Mild cognitive impairment (MCI) https://www.mayoclinic.org/diseases-conditions/mild-cognitive-impairment/symptoms-causes/syc-20354578 is described as having symptoms such as, simple (but habitual) forgetfulness, difficulty following directions and tracking conversations. There is no single cause of MCI, instead MCI is caused by a constellation of conditions to include genetics and living/working/social environments.  Aging related brain shrinking, especially in the area of the brain that controls memory, brain fluid retention and decreased blood flow are some diagnosable causes.

Some studies https://pmc.ncbi.nlm.nih.gov/articles/PMC9013315/#S16 indicate up to one third of all adults over the age of 65 have a range of cognitive issues from MCI to dementia. However, having MCI is not always a path to dementia or Alzheimer’s. In fact, in some cases, MCI can be improved by making lifestyle and environmental changes.

A medical condition https://pmc.ncbi.nlm.nih.gov/articles/PMC8090478/ getting recent attention as one of the causes of MCI is metabolic syndrome (MetS).    The combination of type 2 diabetes, hypertension (high blood pressure), hyperlipidemia (high cholesterol) and, in my opinion, chronic depression are the diagnosis’s which make up MetS.  Any of the four diagnoses’ can, over time, affect brain performance, however the four together present a greater combined risk.

Type 2 diabetes causes blood to become thicker, due to increased sugar, which blocks off tiny blood vessels in the brain. High blood pressure causes micro tears in the same tiny blood vessels leading to blood clotting in those vessels that also block blood flow.  High cholesterol increases the number, and type, of fats circulating in the blood and (you guessed it) interfere with brain blood flow to include blocking microscopic blood vessels.  Lastly, and again this is only my opinion, though it is not a metabolic condition over time chronic depression changes brain chemistry in both availably and utilization leading to areas of the brain not having the right balance of brain chemicals and/or not using brain chemicals correctly.

Reduced blood flow is not the only cause of MCI but some of the factors causing reduced blood flow are, in part, manageable. Some modifiable causes can include medications (do not stop or change the dosage of any prescription medications without consulting your medical provider), vitamin deficiencies, thyroid disorders, reducing emotional and psychological stress, sleep disorders and changes in sight and hearing. There are things under our control that may improve cognition and lessen MCI, but how do we incorporate cognitive improvements into our lives?

• The first and easiest brain friendly choice you can make is – take your medications as prescribed. If it has been a while since you reviewed your medications with a medical provider schedule an appointment to do so.
• If you have MetS, or any of its individual medical conditions, stay on the treatment plan given to you by your provider. If the treatment plan is difficult to follow, consult your provider.
• Schedule an annual eye exam, and a semi-annual hearing test.
• Stay hydrated, remember the brain is 75% fluid. Current fluid recommendations https://pmc.ncbi.nlm.nih.gov/articles/PMC7694182/ for adults over the age of 65 (with good daily nutrition) is 1.6 liters (7 cups)  a day for females and 2.0 liters (9 cups) per day for males.  When exercising these numbers should increase.
• Take charge of online information/make your own algorithm. Limit/schedule screen(s) time, modify your news feed and social media, delete/block triggering information, turn off/manage notifications, as scary as it may sound – switch off your devices for brief periods and slowly (re)learn to embrace quiet.
• Exercise regularly. Exercise at least three days per week for an hour a day, mix up types of exercise – walk/dance/swim/yoga/run/pickleball/lift weights (yes you need to lift weights), schedule exercise times, consult a trainer to help get started, and make exercise a disciplined part of your life.
• Now is the time to learn something new. Try a new sport/activity – hiking/archery/kayaking/Tai Chi/fly fishing, learn an instrument, make art, start writing/blogging, take online classes, go after a certification in something interesting, become an observer and teacher.
• Reacquaint yourself with relaxing/de-stressing. Remember when people did nothing for the simple enjoyment of it? Read books – the kind with paper pages.
• If you have a deck/porch/patio try sitting on it – in a chair, with no devices, go for a walk – just a walk, or sit and breathe and get comfortable with your own thoughts.

In the next several columns we will explore brain health and those things we can do to keep our brain healthy.  I would first like to write two words, so we don’t have to be afraid of them – dementia and Alzheimer’s.  It is extremely unfortunate when individuals and families are touched by either, and both can be frightening to consider. However, there are choices we can make to help to improve the health of our brain, regardless of age.

Let’s start with a page from the brain owner’s manual:

• Our brains weigh approx. three pounds and are about 2% of total body weight. At the same time 15% of our blood flow goes to our brain (approx. 1.5 pints per minute), and our brains consume 25-30% of our daily calories.
• Fluid makes up approx. 75% of the brain, by volume.
• There are 170 billion brain cells making up 86 billion individual neurons (nerve cells).
• Your body creates 750 to 1500 new brain cells each day (about one per minute).
• The brain is approx. 60% fat, making the brain the fattest organ of the body.
• Most brain fat is used in myelin, which insulates each nerve from the others. This is the same as insulation on electrical wire prevents the inner metal part from touching other wires.
• There are approx. 180 separate and distinct areas in each hemisphere (half) of the brain.
• You are both left brained and right brained. Each hemisphere is separate but connected to the other.  Each communicates with the other, sometimes directly and sometimes in consult.
• Our brain cells use a combination of electrical impulses and chemical reactions (dopamine, serotonin etc. – there are over 60 different brain chemicals) to communicate.
• Brain impulses travel at speeds up to 400 feet per second, or over 250 miles per hour.
• If all the blood vessels in our brain were connected end to end, they would be approx. 100,000 miles long (a distance almost halfway to the moon).
• The two main brain fuels are oxygen and sugar.

Our brains are a very complex and busy place.

This may help in a minute-a bit is the smallest unit of digital information, it is equal to answering a single question yes, or no. A byte is 8 bits of information, a gigabyte is one million bytes and an exabyte is one billion gigabytes.  

Our brains processing speed (how quickly our brain can take in, interpret and respond to information) is a maximum of 120 bits per second.  We typically reach this limit processing word recognition, interpreting speech, processing images and reading. When we are in conversation, we can usually process what the other person is saying at a rate of 60 bits per second – on a good day.  This is why when two people are speaking to us at the same time it is difficult to understand, let alone retain, what both are saying – we have exceeded our maximum 120 bit per minute processing speed. Interestingly this is the same reason when driving you instinctively turn the music down when traffic gets heavy, and it suddenly starts raining – you have hit your maximum 120 bits per second and need to reduce information input to devote all available processing speed to not becoming a hood ornament on a Kenworth.

We take in a tremendous amount of information per day, and with each passing day our exposure to information increases.  Each day we can process up to 3.4 gigabytes of information, or information equal to 100,000 words every 24 hours – though much of that information is in the form of TV, podcasts, TikTok videos, and scrolling through Facebook posts about kittens. And we live in a world of 300 exabytes (300 followed by 18 zeros) of available human-made information.  Google alone contains hundreds of billions of webpages and has well over 100,000,000 gigabytes of directly searchable information.

In 1925 newspapers were the main source of information, a daily newspaper of the day contained an average of 25,000 total words. Only 19% of American homes owned a radio and the concept of national radio stations was still developing.  Most information came from local, or regional, sources. Currently you can check the weather in Shanghai in less than a second and practically every news source on the planet is immediately available at the touch of a screen

We have the same brain function our grandparents had in 1925, with the same 120 bit maximum processing speed.  But we are processing many times that amount of information in the same 24 hours.   For those of us old enough to have lived from newspapers, radio and primitive TV to laptops, iPads and cellphones, our brains have made huge adaptations in the ability to process information. And all this information, along with the technology that supports it, adds to the difficulty of processing day-to-day activities. Like trying to open one of those thin, stuck together plastic bags every time you want to buy a tomato.

As we are limited to how much we can process, choosing what to process becomes important.  There are times we are on auto pilot (have you driven to the store but can’t remember details of how you got there), but most of the time we are aware of the increasing input/stimulation around us.  Focusing on this awareness, or at least occasionally checking in with yourself, and self-responding early to escalating input can go a long way in making your brain, and yourself much happier.

It’s a new year!  Hope, a new start at new things as well as the opportunity to revisit old things in new ways, gives meaning to this time of year.  This annual reset also gives us pause to consider different approaches to past struggles, be they emotional, behavioral or physical.  We hope you will consider your local South Sound YMCA branch as a partner in planning and implementing your wishes and goals.

Let’s start the year with a rarely discussed part of overall fitness, stamina. The duo of Merriam and Webster define stamina as, “the bodily or mental capacity to sustain a prolonged stressful effort or activity”.  However, stamina is more than that, it is not endurance – it is that place past endurance. It is having the mental and physical reserves to meet and exceed not just challenges but blatant adversity. Stamina is the fuel of courage and resolve.

Over years of emergency room Nursing, I found two main things helped people survive the worst day of their life, an uncommon will to live and stamina. Stamina in form of deep physical and mental reserves, in other words both gas tanks were full and available to fuel the next 48 to 72 hours of incredible need.  Granted this is worst case scenario, but it gives you an idea we are not talking about something superficial. Instead, this is something that it is part of our being.

Stamina is developed over time, with awareness and purpose.  It is a combination of routinely overcoming physical limits and learning to navigate complex emotional and mental challenges, all the while remaining grateful. Time is the key; stamina does not weave its way through us over weeks or months, but years.  The time-bound process of imbedding stamina is one of many ways age is in our favor.

In another time stamina would be defined as toughness, grit, guts.  Those of us raised by depression era parents and whose mothers and fathers won World War Two understand these terms.  So, in this age of AI and same day Amazon Prime deliveries how do we connect to our parent’s strength, fortitude and willpower? Discipline.  We do it through discipline, the same way they did

Discipline is doing the right thing, for the right reason regardless the obstacles.  You find discipline going for your daily walk on a cold, windy, rainy morning because of the weather challenge, not staying in bed because the weather is challenging.   You embrace discipline when you give grace to the person who beat you to a parking space, and not succumb to self-defeating anger. And like many things, discipline weakens if not regularly exercised.

By exercising discipline you can, in turn, build stamina.  You build physical stamina by going a minute more on the treadmill than last time, pushing out an extra rep on the chest machine, or swimming a half lap more than yesterday.  Mental stamina can be incrementally improved by focusing, read a book (a whole book) and begin by keeping your reading focused for 15 minutes at a time.  Develop your emotional stamina by learning to take a breath before negative feelings overwhelm you, then learn to let one breath become two then three.

Building stamina, in any of these three areas, is not easy.  That’s the point, and the reason stamina is becoming rare in both individuals and societies. This year challenge yourself, improve yourself emotionally, physically and mentally.  And you need no other reason than a simple desire to be a better person.

With the Holidays and a new year upon us, there is no better time for reflection and hope.  Considering our somewhat older and perhaps retired lives, it is easy to slide toward complacency and lose sight of the path we are on and where we would like that journey to take us.

I am biased toward higher levels of wellness and health being part of a full and enriched life.  My Nursing career has shown me that without a foundation of good health (as that means to you) it is difficult to reach personal potential, regardless of age.  And with age we can become comfortable with our current levels of physical, mental and emotional health, easily forgetting there are many things to explore and experience.  How do we reconnect ourselves to our lives?

Step one, become active.  In other words, do more in different ways than you currently are. The body is connected to the mind and the mind to the body – inseparable yet unique.  Both loves to be exercised, challenged and exposed to the new and unexplored.  Great joy can come from body and mind overcoming the perceived insurmountable together.  Age is not a barrier to learning and growth.

Step two, improve yourself physically.  All it takes that most rare behavior, discipline.  We all know discipline very well; we couldn’t successfully have reached our age without it.  Did you serve in the military?  If so, discipline is imbedded in your DNA.  Remember those early mornings you drug yourself out of bed to face another frustrating day of work because it was the right thing to do for your family? Then you have no shortage of discipline.  It is simply a matter of focusing the discipline you have developed over time on beginning a daily walk, going to the gym three days a week, taking a yoga class, or diving into a regular swimming practice.

Step three, exercise your mind.  Our brain becomes accustomed to patterns, both of thought and daily life. It becomes comfortable doing only expected things and gets grumpy when we ask more if it.  Ask more of your brain.  Change up your daily activities, brush your teeth with your non-dominate hand, go through the grocery store the opposite direction, put your pants on standing up.  Scroll less, read more. And when you read, challenge yourself with new authors and new topics.

Last step, be kind to yourself.  We didn’t get chronologically here without hitting a few bumps in the road – maybe a guardrail or two. Give yourself the grace to appreciate the life you have lived and the space to embrace your future.  It is easy for rumination to overwhelm us at times.  That’s okay, it happens but only visit those memories for what they were and refuse to let them describe who we are today.  In the words of Stephen Stills, “don’t let the past remind us of what we are not now”.

The improvement of emotional, mental and physical wellbeing is not restricted by age, circumstance nor perspective. Introspection is readily available to all of us and there are times even simple journeys can bring new, never before seen vistas.

Merry Christmas and I hope your new year is full of wonder and happiness!

As always, I would enjoy hearing about the challenges and successes of your fitness journey.  Please feel free to email me at hankinsb@ssymca.net .
