By Dr. Mercola
It was once believed that brain function
peaked during early adulthood and then slowly declined, leading to lapses in
memory and brain fog during your golden years.
Now it's known that our modern lifestyle plays a significant
role in contributing to cognitive decline, which is why exposure to toxins,
chemicals, poor diet, lack of sleep, stress, and much more can actually
hinder the functioning of your brain.
The flipside is also true in that a healthy lifestyle can
support your brain health and even encourage your brain to grow new neurons,
a process known as neurogenesis.
Your brain's hippocampus, i.e. the memory center, is
especially able to grow new cells and it's now known that your hippocampus
regenerates throughout your entire lifetime (even into your 90s), provided
you give it the tools to do so.
These "tools" are primarily lifestyle-based, which is
wonderful news. You don't need an expensive prescription medication or any
medical procedure at all to boost your brain, and your memory. You simply
must try out the following tricks to improve your memory.
7 Lifestyle-Based Ways to Improve Your Memory
1. Eat Right
The foods you eat – and don't eat – play a crucial role
in your memory. Fresh vegetables are essential, as are healthy fats and avoiding sugar
and grain carbohydrates. You can find detailed
information about nine
foods for brainpower here.
For instance, curry, celery, broccoli,
cauliflower, and walnuts contain antioxidants and other compounds that
protect your brain health and may even stimulate the production of new
brain cells.
Increasing your animal-based omega-3 fat
intake and reducing consumption of damaged omega-6 fats (think processed
vegetable oils) in order to balance your omega-3 to omega-6 ratio, is
also important. I prefer krill oil to fish oil, as krill oil also
contains astaxanthin,
which not only protects the omega-3 fats from oxidation but also appears
to be particularly beneficial for brain health.
Coconut oil is another healthful fat for brain function.
According to research
by Dr. Mary Newport, just over two tablespoons
of coconut oil (about 35 ml or 7 level teaspoons) would supply you with
the equivalent of 20 grams of medium-chain triglycerides (MCT), which is
indicated as either a preventative measure against degenerative
neurological diseases, or as a treatment for an already established
case.
2. Exercise
Exercise encourages
your brain to work at optimum capacity by stimulating nerve cells to
multiply, strengthening their interconnections and protecting them from
damage.
During exercise nerve cells release proteins known as
neurotrophic factors. One in particular, called brain-derived
neurotrophic factor (BDNF), triggers numerous other chemicals that
promote neural health, and directly benefits cognitive functions,
including learning.
A 2010 study on primates published in Neuroscience also
revealed that regular exercise not only improved blood flow to the
brain, but also helped the monkeys learn new tasks twice as quickly as
non-exercising monkeys.
This is a benefit the researchers believe would hold true
for people as well.1In
a separate one year-long study, individuals who engaged in exercise were
actually growing and expanding
the brain's memory center one
to two percent per year, where typically that center would have
continued to decline in size.
To get the most out of your workouts, I recommend a
comprehensive program that includes high-intensity
interval exercise, strength training,
stretching, and core work, along with regular intermittent
movement.
3. Stop Multitasking
Used for decades to describe the parallel processing
abilities of computers, multitasking is now shorthand for the human
attempt to do simultaneously as many things as possible, as quickly as
possible. Ultimately, multitasking may actually slow you down, make you
prone to errors as well as make you forgetful.
Research shows you actually need about eight seconds to
commit a piece of information to your memory, so if you're talking on
your phone and carrying in groceries when you put down your car keys,
you're unlikely to remember where you left them.
The opposite of multitasking would be mindfulness, which
helps you achieve undistracted focus. Students who took a mindfulness
class improved reading comprehension test scores and working memory
capacity, as well as experienced fewer distracting thoughts.2
If you find yourself trying to complete five tasks at
once, stop yourself and focus your attention back to the task at hand.
If distracting thoughts enter your head, remind yourself that these are
only "projections," not reality, and allow them to pass by without
stressing you out. You can then end your day with a 10- or 15-minute
meditation session to help stop your mind from wandering and relax into
a restful sleep.
4. Get a Good Night's Sleep
Research from Harvard indicates that people are 33
percent more likely to infer connections among distantly related ideas
after sleeping,3 but
few realize that their performance has actually improved. Sleep is also
known to enhance your memories and help you "practice" and improve your
performance of challenging skills. In fact, a single night of sleeping
only four to six hours can impact your ability to think clearly the next
day.
The process of brain growth, or neuroplasticity,
is believed to underlie your brain's capacity to control behavior,
including learning and memory. Plasticity occurs when neurons are
stimulated by events, or information, from the environment. However,
sleep and sleep loss modify the expression of several genes and gene
products that may be important for synaptic plasticity.
Furthermore, certain forms of long-term potentiation, a
neural process associated with the laying down of learning and memory,
can be elicited in sleep, suggesting synaptic connections are
strengthened while you slumber.
As you might suspect, this holds true for infants too,
and research shows that naps can give a boost to babies' brainpower.
Specifically, infants who slept in between learning and testing sessions
had a better ability to recognize patterns in new information, which
signals an important change in memory that plays an essential role in
cognitive development.4 There's
reason to believe this holds true for adults, too, as even among adults,
a mid-day nap was found to dramatically boost and restore brainpower.5 You

tips to help you get the shut-eye you need here.

5. Play Brain Games
If you don't sufficiently challenge your brain with new,
surprising information, it eventually begins to deteriorate. What
research into brain plasticity shows us, however, is that by providing
your brain with appropriate stimulus, you can counteract this
degeneration.
One way to challenge your brain is via 'brain games,'
which you can play online via Web sites like Lumosity.com. Dr. Michael
Merzenich, professor emeritus at the University of California, who I interviewed
two years ago, has pioneered research in brain
plasticity (also called neuroplasticity) for more than 30 years, has
also developed a computer-based brain-training program that can help you
sharpen a range of skills, from reading and comprehension to improved
memorization and more.
The program is called Brain HQ, and the website has many
different exercises designed to improve brain function and it also
allows you to track and monitor your progress over time. While there are
many similar sites on the Web, Brain HQ is one of the oldest and most
widely used.
If you decide to try brain games, ideally it would be
wise to invest at least 20 minutes a day, but no more than five to seven
minutes is to be spent on a specific task. When you spend longer amounts
of time on a task, the benefits weaken. According to Dr. Merzenich, the
primary benefits occur in the first five or six minutes of the task. The
only downside to brain games is that it may become just another "task"
you need to fit into an already busy day. If you don't enjoy brain
games, you can also try learning a new skill or hobby (see below).
6. Master a New Skill
Engaging in "purposeful and meaningful activities"
stimulates your neurological system, counters the effects of
stress-related diseases, reduces the risk of dementia and enhances
health and well-being.6 A
key factor necessary for improving your brain function or reversing
functional decline is the seriousness
of purpose with
which you engage in a task. In other words, the task must be important
to you, or somehow meaningful or interesting — it must hold your
attention.
For instance, one study revealed that craft activities
such as quilting and knitting were associated with decreased odds of
having mild cognitive impairment.7 Another
study, published earlier this year, found that taking part in
"cognitively demanding" activities like learning to quilt or take
digital photography enhanced memory function in older adults.8 The
key is to find an activity that is mentally stimulating for you.
Ideally this should be something that requires your undivided attention
and gives you great satisfaction… it should be an activity that you look
forward to
doing, such as playing a musical instrument, gardening, building model
ships, crafting or many others.
7. Try Mnemonic Devices
Mnemonic devices are memory tools to help you remember
words, information or concepts. They help you to organize information
into an easier-to-remember format. Try:
-
Acronyms (such as PUG for "pick up grapes")
-
Visualizations (such as imagining a tooth to remember
your dentist's appointment)
-
Rhymes (if you need to remember a name, for instance,
think "Shirley's hair is curly)
-
Chunking, which is breaking up information into
smaller "chunks" (such as organizing numbers into the format of a
phone number)
3 More Smart Tips for Brainpower
If you're serious about improving your
memory and your cognitive function, you'll also want to know about these
three important variables for brain health.
Vitamin D
Activated vitamin
D receptors
increase nerve growth in your brain, and researchers have also located
metabolic pathways for vitamin D in the hippocampus and cerebellum of
the brain, areas that are involved in planning, processing of
information, and the formation of new memories. In older adults,
research has shown that low vitamin D levels are associated with poorer
brain function, and increasing levels may help keep older adults
mentally fit. Appropriate sun exposure is all it takes to keep your
levels where they need to be for healthy brain function. If this is not
an option, a safe tanning bed is the next best alternative, followed by
a vitamin D3 supplement.
Intermittent Fasting
Contrary to popular belief, the ideal fuel for your brain
is not glucose but ketones, which is the fat that your body mobilizes
when you stop feeding it carbs and introduce coconut oil and other
sources of healthy fats into your diet. A one-day fast can help your
body to "reset" itself, and start to burn fat instead of sugar. Further,
it will help you to reduce your overall calorie consumption, which
promotes brain cell growth and connectivity.
As part of a healthy lifestyle, however, I prefer an intermittent
fasting schedule
that simply calls for limiting your eating to a narrower window of time
each day. By restricting your eating to a 6-8 hour window, you
effectively fast 16-18 hours each day. To learn more, please see this
previous intermittent
fasting article.
Gut Health
Your gut is your "second brain," and your gut bacteria
transmits information to your brain via the vagus nerve, the tenth
cranial nerve that runs from your brain stem into your enteric nervous
system (the nervous system of your gastrointestinal tract). There is a
close connection between abnormal gut flora and abnormal brain
development, and just as you have neurons in your brain, you also have
neurons in your gut -- including neurons that produce neurotransmitters
like serotonin, which is also found in your brain and is linked to mood.
Quite simply, your gut
health can impact your brain function, psyche,
and behavior, as they are interconnected and interdependent in a number
of different ways. In addition to avoiding sugar, one of the best ways
to support gut health is to consume beneficial bacteria. You can use a
probiotic supplement for this, but I'm particularly fond of using fermented
vegetables, because they can deliver
extraordinarily high levels of beneficial bacteria. Most people aren't
aware that in a healthy serving of sauerkraut – two to three ounces or
so – you're getting the equivalent of nearly 100 capsules of the
highest-potency probiotic you can buy. It's clearly one of the most
cost-effective alternatives.
The Choline-Brain Connection
Choline is an essential nutrient your
body makes in small amounts. However, you must consume it through your diet
to get enough. In adults, choline helps keep your cell membranes functioning
properly, plays a role in nerve communications, prevents the buildup of
homocysteine in your blood (elevated levels are linked to heart disease) and
reduces chronic inflammation. In pregnant women, choline plays an equally,
if not more, important role, helping to prevent certain birth defects, such
as spina bifida, and playing a role in brain development.
Prior research has concluded that choline intake during
pregnancy "super-charged" the brain activity of animals in utero, indicating
that it may boost cognitive function, improve learning and memory, and even
diminish age-related memory decline and the brain's vulnerability to toxins
during childhood, as well as conferring protection later in life.9
If you're pregnant, making sure your diet includes plenty of
choline-rich foods is important, as research shows higher choline intake led
to changes in epigenetic markers in the fetus.10 Specifically,
it affected markers that regulate the hypothalamic-pituitary-adrenal (HPA)
axis, which controls hormone production and activity. The changes in fetal
genetic expression will likely continue into adulthood, where they play a
role in disease prevention. Eggs and meat are two of the best dietary
sources of choline; if you're a vegan or vegetarian who does not consume any
animal foods, you may be at risk of deficiency and may want to consider
supplementation.
