The more we learn, the more we wish to continue learning. Understanding the
world is like assembling a jigsaw puzzle. The more pieces we fit, the clearer
the image and the greater the urge to learn and fill in even more pieces.
Increasing one’s knowledge can be compared to an avalanche: once the process
starts, it gathers a momentum of its own. Perseverance and some initial
prompting are required, but the rewards soon pay off. Minds are kept young by
continual use, and mentally active people live longer. I consider
mind-enhancement to be a lifelong process. Centuries ago Rene Descartes said,
“It is not enough to have a good mind. The main thing is to use it well.”
Emotional Connections
During this process of intellectual enhancement, keep in mind
that we also need to grow emotionally. Although supplements can help provide the
basic ingredients for proper mental functioning, they cannot, on their own,
help us develop healthy relationships. In order for us to feel truly fulfilled,
it helps to cultivate healthy connections on multiple levels.
The need for connection may be fulfilled in several ways. On a personal level,
we can connect with fellow human beings through friendship, physical intimacy,
romance, marriage, and family. We can also satisfy our need for connection with
cats, dogs, other animals, and nature as a whole. We satisfy the urge to belong
to something larger than ourselves by joining religious, humanistic,
philosophic, or any number of community groups. As a rule, the more ways we
connect, the happier we become.
Supplements can sometimes help in this regard by lifting our mood and improving
our motivation to become social and interact with others.
Smart Eating
Mental health is, in many ways, linked to physical health. The
cardiovascular system supplies blood and oxygen to the brain. When the arteries
to the brain are clogged, the blood supply to important neural centre's
decreases. Cardiovascular disease can often foretell cognitive decline—those who
have poor blood flow suffer mental decline faster than those with good vascular
health.
Just about every step you take to improve your physical well-being will
influence your brain health—especially the right diet. Since the topic of
healthy eating has been covered thoroughly in many books and articles, I just
wish to make a few important points.
Breakfast is essential for good thinking. Dr. David Benton and colleagues from
the University of Wales-Swansea, in the United Kingdom, studied the effects of
skipping breakfast versus eating breakfast (Benton 1998). Morning fasting was
found to adversely affect the ability to recall a word list and stories read
aloud, as well as to recall items while counting backward. However, the failure
to eat breakfast did not affect performance on an intelligence test. The
researchers conclude that breakfast influences tasks requiring aspects of
memory, partly through increasing blood-sugar levels.

Sustain the Brain: Nutritional assistance
Certain types of mental decline result from exposure to toxins
such as lead, mercury and aluminium as well as from allergies, stress or low
nutrient levels in the tissues, which appear to contribute to brain
inflammation, scarring and cognitive impairment.
The aging brain can have low levels of such nutrients for several reasons
including a poor diet or inadequate nutrient absorption. Thus, antioxidants and
B vitamins should top anyone's list of brain food. Brain food includes all your
antioxidant foods such as citrus fruits, plenty of green leafy vegetables, fish,
meat and grains.
Hair and Tissue mineral analysis reflect the current internal toxic environment
and gives you an idea of the potential health issues for the future.
Pantothenic Acid (B5)
Also known as vitamin B5, pantothenic acid is essential for a
number of basic bodily functions--from growth to reproduction. It participates
in the continual breakdown of carbohydrates, fats, and proteins from food,
converting them into compounds the body can use. This vitamin also produces
numerous enzymes and helps maintain precise communication between the central
nervous system and the brain.
The body relies on pantothenic acid to help the adrenal glands
produce stress hormones during times of both psychological and physical strain.
This property makes it potentially useful for dealing with emotional upset,
depression, anxiety, migraines, chronic fatigue, and withdrawal from alcohol or
tobacco. It is commonly taken as part of a vitamin B complex supplement for
these purposes. In addition, pantothenic acid may reduce the occurrence of
migraines by participating in the production of the brain chemical serotonin;
some research indicates that serotonin is present at abnormally low levels in
migraine sufferers.
B6
Technically an umbrella term used to describe three B vitamins (pyridoxine,
pridoxal, pyridoxamine), vitamin B6 partakes in no fewer than 100 chemical
reactions throughout the body. It functions primarily as a coenzyme, working
along with other enzymes to speed up chemical reactions in cells. Incredibly,
government surveys indicate that one-third of adults are deficient in this key
nutrient. The elderly, pregnant or nursing women, oral contraceptive users, and
smokers are particularly at risk for a deficiency.
Vitamin B6 helps manufacture the building blocks of proteins known as amino
acids. It also takes part in producing brain neurotransmitters (chemical
messengers) such as serotonin, in releasing energy stored in cells, and in
manufacturing red blood cells. Vitamin B6 also helps to keep hormones in balance
and the immune system functioning properly.
CoQ10
CoQ10, also known as ubiquinone or ubiquinol, is a naturally occurring nutrient
in each cell. CoQ10 is found in foods, particularly in fish and meats. In
addition to playing a significant role in the energy system of each of our
cells, CoQ10 is an excellent antioxidant. A member of a family of compounds
called quinones, coenzyme Q10 (sometimes called Co Q10) works in concert with
enzymes (hence the name "coenzyme") that are necessary for chemical reactions
throughout the body. It is particularly abundant in high-energy-demanding cells,
such as those found in the heart. In addition, coenzyme Q10 acts as a powerful
antioxidant to prevent the cellular damage caused by unstable oxygen molecules
called free radicals.
Because the body's production of coenzyme Q10 slows with age, some doctors
routinely recommend the supplement to anyone over age 50. Indeed, many people
take it as a general energy enhancer; others take it to fight age-related memory
loss. Its antioxidant actions have even been enlisted to slow the progression of
Alzheimer's disease, a memory-robbing, degenerative disease most common in older
individuals. Further research is needed to flesh out exactly how supplemental
coenzyme Q10 and its antioxidant properties might positively affect the aging
process.
Studies of CoQ10 have mostly focused on its role in heart disease. However,
CoQ10 has a role in brain function, too. Initial studies have shown those who
take CoQ10 notice that this nutrient provides energy and mental clarity.
Choline and Lecithin
Lecithin is a fatty substance manufactured in the body. Lecithin is considered
an excellent source of choline, one of the B vitamins. Once in the body, a key
component of lecithin--phosphatidylcholine--breaks down into choline. Now
available in dietary supplement form, phosphatidylcholine (PC) might be thought
of as a purified extract of lecithin. It is commonly recommended for treating
liver, nerve, and a variety of other conditions, including multiple sclerosis
and memory loss.
Many nutritionally oriented doctors consider phosphatidylcholine a valuable
nerve-building nutrient that might be able to help slow or reverse memory loss.
As a phospholipid--a fat-soluble substance--this nutrient serves as a major
structural component of brain cells. Perhaps even more important,
phosphatidylcholine plays a key role in supplying sufficient choline to the
brain, where it's used to manufacture the neurotransmitter acetylcholine. Levels
of acetylcholine are known to dwindle with age and this decline is associated
with age-related memory impairment.
Choline is an essential nutrient, a B-vitamin. It can be
manufactured in the body (from the amino acid methionine), although there is
some debate whether it can be made in sufficient amounts for optimal health.
Folic acid and vitamin B12 are also needed to process choline. Choline plays a
role in brain development (as an amine precursor for the neurotransmitter
acetylcholine), liver function and cardiovascular health.
Choline is an important constituent of cell membranes, so choline has functions
in virtually every bodily system. Choline participates in lipid (fat) transport
in the body and may reduce accumulation of fat in the liver. As a dietary
supplement and ergogenic aid, however, claims surrounding choline are due mostly
to its role as a component of acetylcholine, the neurotransmitter needed for
conduction of nerve signals and brain function. Claims in this area typically
involve mental performance, memory and reaction time. Supplementing with choline
has been found to aid in memory, brain development, act to protect the
cardiovascular, promotes energy and delay fatigue in athletes.
It is an essential nutrient required by the body to make several important
compounds necessary for healthy cell membranes. Choline helps form
phosphatidylcholine, the primary phospholipid of cell membranes. Choline is also
the precursor to acetylcholine, one of the crucial brain chemicals involved in
memory. A major use of choline in the body is the formation of betaine, an
important methyl donor. Furthermore, choline helps transport of lipids from the
liver. Choline is an essential precursor of acetylcholine, a stimulatory
neurotransmitter. It also helps in the production of lipotropic agents which
converts fats into useful products and aids in the production of HDL (good)
cholesterol.*
Phosphatidylserine
Phosphatidylserine (PS) is a phospholipid, a type of fat found in
every cell in the body. It is particularly concentrated in the brain, where it
has the important task of keeping cell membranes fluid, flexible and primed for
nutrient absorption. PS also plays a critical role in supporting nerve tissue;
it aids proper release and reception of neurotransmitters in the brain, for
example. In short, PS helps to keep memory-related pathways functioning
smoothly.
Research indicates that phophatidlserine lessens age-related
decline in brain functioning. Several studies, some of them quite well-designed,
have been conducted in the United States and Europe to examine the effect of PS
on preventing or reversing a decline in higher mental functions (memory,
concentration, abstract thought and judgment ) in older adults already
experiencing difficulties in these areas. In one 12-week study of 149 adults
ages 50 to 75, those who took 300 mg PS a day were better able to learn and
recall names, faces and numbers than those taking a placebo. All the
participants had been diagnosed with age-associated memory impairment. The
greatest benefit was observed in participants who had been most impaired when
the study started. PS supplements were also more effective than a placebo in a
six-month study involving 494 individuals between ages 65 and 93. All suffered
from moderate to severe senility. When compared to those who took a placebo,
those assigned to the PS treatment had marked short-term improvements in their
ability to memorize, concentrate, and learn new material.
Alpha –Lipoic Acid
In the late 1980s, scientists realized that alpha-lipoic acid, a
compound initially classified as a vitamin when it was discovered three decades
earlier, possessed potent antioxidant properties that could prevent healthy
cells from getting damaged by unstable oxygen molecules called free radicals. In
fact, this vitamin like compound has proved to be many times more potent than
such old guard antioxidants as vitamins C and E. As a perk, it even recycles C
and E (as well as other antioxidants), enhancing their effectiveness.
Because it dissolves in both water and fat, this so-called
"universal antioxidant" is able to scavenge more wayward free-radical cells than
most antioxidants, the majority of which tend to dissolve in either fat or water
but not both. Alpha-lipoic acid can reach tissues composed mainly of fat, such
as the nervous system, as well as those made mainly of water, such as the heart.
Results from animal studies indicate that alpha-lipoic acid may
improve long-term memory. Much remains to be learned about whether this occurs
in humans, but it may be worth trying this powerful antioxidant when a disease
such as Alzheimer's starts to erode memory. In addition, alpha-lipoic acid holds
promise for preserving brain cells following a stroke or other type of trauma
that restricts blood flow to the brain.
Omega-3
Scientists made one of the first associations between omega-3s and human health
while studying the Inuit (Eskimo) people of Greenland in the 1970s. As a group,
the Inuit suffered far less from certain diseases (coronary heart disease,
rheumatoid arthritis, diabetes mellitus, psoriasis) than their European
counterparts. Yet their diet was very high in fat from eating whale, seal, and
salmon. Eventually researchers realized that these foods were all rich in
omega-3 fatty acids, which provided real disease-countering benefits.
Researchers continue to explore this exciting field. They've
found that without a sufficient supply of polyunsaturated omega-3s, the body
will use saturated fat to construct cell membranes. The resulting cell
membranes, however, are less elastic, a situation that can have a negative
effect on the heart because it makes it harder to return to a resting state.
The brain is remarkably fatty: In fact, this organ is 60% fat and needs omega-3s
to function properly. Now researchers have discovered a link between mood
disorders and the presence of low concentrations of omega-3 fatty acids in the
body.
Apparently, omega-3s help regulate mental health problems because
they enhance the ability of brain-cell receptors to comprehend mood-related
signals from other neurons in the brain. In other words, the omega-3s are
believed to help keep the brain's entire traffic pattern of thoughts, reactions,
and reflexes running smoothly and efficiently.
Tryptophan
5-HTP is a derivative of the amino acid tryptophan (a hydroxyl group added to
the 5-position). In the body, tryptophan is converted into 5-HTP, which then can
be converted into serotonin (a potent neurotransmitter in the brain). Although
5-HTP is not found at any significant level in a normal diet, tryptophan is
found in a wide variety of protein foods. The 5-HTP used in dietary supplements
is derived from the seeds of and African plant (Griffonia simplicifolia).
Tryptophan supplementing has been found to relieves mild to moderate depression,
relieves insomnia and promotes restful sleep, promote weight loss by suppressing
appetite and reduces overall sensation of pain (migraine headaches,
fibromyalgia, general muscle pain)
5-HTP is typically used to treat mild depression based on the theory that as a
precursor to serotonin, supplements of 5-HTP can increase serotonin levels and
influence mood, sleep patterns and pain control. The amino acid, tryptophan, can
also be broken down in the body to yield ribose and/or NAD – both of which have
been associated with increased energy levels. While these are certainly logical
theories, the scientific evidence supporting them remains moderate at best.
In a few small studies, however, 5-HTP has been shown to be as effective as
prescription antidepressant medications – and with fewer side effects.
Dimethylglycine (DMG)
Dimethylglycine (DMG), is a
methyl donor that helps in the production of several brain chemicals and hence
improve mood, energy, wellbeing, alertness, concentration, and visual clarity.
Dimethylglycine (DMG)is found in a variety
of plant and animal sources and is used in the conversion of homocysteine to
methionine. Maintaining normal homocysteine levels is important for the health
of the cardiovascular system. Dimethylglycine (DMG) has been shown to help protect the liver and
raise S-adenosylmethionine (SAM-e) levels, in animal studies.
Ginseng
For thousands of years, Chinese medicine has used the herb ginseng as a memory
tonic with the belief that ginseng can improve learning and memory, especially
in aging humans. Recent studies have sought to validate this claim. Experiments
done on rats have shown that ginsenosides, the saponins of ginseng, can
partially prevent scopolamine-induced memory deficits in rats. Ginsenosides are
thought to increase choline uptake in the central cholinergic nervous system,
which plays important roles in learning and memory.
Further experiments have shown that ginseng extracts can improve
the retention of learned behaviour in young (aged 3 months) as well as old (aged
26 months) rats. The potential beneficial effects of the polysaccharide
fractions of ginseng on learning and memory still warrant further
experimentation. The favourable effects of ginseng on learning and memory make it
a promising drug for the use in geriatric practice.
Ginseng may also help improve memory in patients with mild dementia following a
stroke, according to the results of a randomized pilot study reported at the
American Stroke Association's 28th International Stroke Conference. However,
larger, controlled trials are needed to evaluate safety and efficacy.
Ginkgo Biloba
Studies now demonstrate ginkgo works for normal age-related memory loss,
although prevention is better than a cure. Ginkgo (Ginkgo biloba) has been well
documented to improve cerebral blood flow and to have antioxidant activity on
the nerves and vasculature. Ginkgo may also reduce the age-related decline of
neurotransmitters and receptors. Through these actions ginkgo may improve
cognitive function and reduce central nervous system degeneration.
Extracted from the ancient ginkgo tree, ginkgo biloba is
considered the best of all brain-boosting supplements on the market. Studies of
people with Alzheimer's disease show that ginkgo enhances blood flow to the
brain and improves memory recall. In addition, ginkgo is a potent
anti-inflammatory and antioxidant. Ginkgo does thin the blood and can clash with
some medications, especially blood thinners; so check with your doctor before
taking and make sure not to take before a surgery.
Bacopa
Bacopa is an Ayurvedic medicine used in India for memory
enhancement, epilepsy, insomnia, and as a mild sedative. Some studies have shown
that bacopa has antioxidant effects (Tripathi 1996), while a study on rats
showed bacopa administration improves learning skills (Singh 1982). Dr.
Shailinder Sodhi, an expert in Ayurvedic herbs, reports, “Bacopa is a brain
tonic that provides relief from stress; it energizes but does not act as a
stimulant. Bacopa is often taken in the morning and the effects can last all
day. Users notice alertness, clarity of vision, and stimulation of appetite. The
dosage is 125 mg for 50 percent bacosides standardized extract, or 10 ml of the
liquid extract.” Bacopa has potential as a cognitive aid, but a few more studies
are needed in order to determine which neurotransmitters this herb influences
and to determine its long-term effectiveness and safety profile.
