Conclusions from
research point toward major consequences from habits of worry and anxiety. Recent studies by researchers at Baycrest
Health Sciences’ Rotman Research Institute have shown that symptoms of anxiety
in people diagnosed with mild cognitive impairment (MCI) increase the risk of a
speedier decline in cognitive functions, independent of depression, which is
another risk marker. For MCI patients with mild, moderate or severe anxiety,
Alzheimer's risk increased by 33%, 78% and 135% respectively. MCI patients who
had reported anxiety symptoms at any time over the follow-up period had greater
rates of atrophy in the medial temporal lobe regions of the brain, which are
essential for creating memories and which are implicated in Alzheimer’s. More

Worry, Anxiety, and Your Brain, 3
One of the individuals I
was mentoring through an educational process gave me a book written by Richard
Carlson entitled: “Don’t Sweat the Small Stuff . . . and It’s All Small Stuff.” Part
of a series on ‘don’t sweat the small stuff,’ it advertised ‘Simple
Ways to Keep the Little Things From Taking Over Your Life.’ I thought it was a
wonderful title and we chuckled about it at the time. In retrospect, however, it is a
particularly excellent perspective. Today I tried to recall some of the things that
were worrying the student at the time and I cannot recall any of them. What did
you worry about last year or the year before? Whatever they were, it likely doesn’t
matter now—the worries and anxieties. The consequences to your brain and immune
system, however, may matter a great deal. More tomorrow.

Worry, Anxiety, and Your Brain, 2
Think of the four
emotions as four categories: joy, anger, fear, and sadness. Many languages,
including English, have hundreds of words for emotions and feelings (because
they lump those two words together and sometimes use them interchangeably or
synonymously). That’s unfortunate since they represent different states and are
believed to follow different pathways through the brain. It is my brain opinion
that you can place each of the hundreds of words in one of those four
categories. Worry and anxiety would go into the bucket of ‘fear’ since fear is
all about helping you recognize that you are unsafe unless the fear is not
about a bona fide situation of actual danger and represents your thoughts and
beliefs about imaginary fears (e.g., I’m not smart enough or good looking
enough or wealthy enough or . . .). Unfortunately, imaginary fears can still
trigger the stress response . . . More tomorrow.

Worry, Anxiety, and Your Brain
Recently while lecturing
in the United Kingdom, I was chatting with the producer of a TV program on
which I was being interviewed. Both of us had heard someone say, “I was so
anxious I was sure I was losing my mind!” Worry and anxiety seem to be global
problems and we chatted briefly about their contribution to memory problems and
even dementia. Flying back home I decided to do so blogs on the topic. First a
reminder that I talk about four core emotions because they can be seen on the
face of the fetus: joy, anger, fear, and sadness. Three of those (anger, fear,
and sadness) are said to be ‘protective emotions’ because they help us manage a
variety of types of events and situations. The protective emotions appear to be
aligned with the right hemisphere of the brain, while the left hemisphere
lights up on brain scans when the emotion of joy is being experienced. More

Origin of Phrases, 6
Origin of Phrases, 6
1.
Cobweb: The Old English word for ‘spider’ was
‘cob.’
2.
Riff-raff: The Mississippi River was the
main way of traveling from north to south. River-boats carried passengers and
freight but they were expensive so most people used rafts. Everything had the
right of way over rafts which were considered cheap. The steering oar on the
rafts was called a ‘riff’ and this transposed into riff-raff, meaning low
class.
3.
Ship state rooms: Traveling by steamboat was
considered the height of comfort. Passenger cabins on the boats were not
numbered. Instead they were named after states. To this day cabins on ships are
called staterooms.

Beating Addiction
Because everything starts in the brain, my brain's opinion is that beating addiction starts by learning something about the brain and choosing a mindset of recovery. One resource I use is The
Chemical Carousel: What Science Tells Us About Beating Addiction by Dirk Hansen. He
explains in easy-to-understand language what happens in the brain when a molecule
of cocaine or gin or THC finds its way there. And outlines the combination of
molecular messengers (serotonin, dopamine, norepinephrine, glutamate, and CRF) that
hit the brain reward system; pointing out that “everything that follows, from
behavioral problems to broken marriages, from jail time to rehab, is a result
of changes in infinitesimally small amounts of these chemicals in the brain.” Addictive
behaviors represent a ‘disease’ in my brain’s opinion and need to be dealt with
like all other diseases. Sooner than later, as they always result in negative
outcomes . . .

Pot Withdrawal, 2
For some marijuana users, withdrawal can be a real challenge. Fortunately, over the last decade or so, a body of knowledge is being collected about the
symptoms of pot withdrawal. For example, Dirk Hansen outlined some of these
symptoms in his blog: “The
syndrome is marked by irritability, restlessness, generalized anxiety,
hostility, depression, difficulty sleeping, excessive sweating, loose stools, loss
of appetite, and a general ‘blah’ feeling.” [You may want to access
his blogspot for additional information.] For
overall health, productivity, relationships, and success in life, I recommend
that people put in the work to free themselves from addictive behaviors,
especially those related to substances. They directly impact your brain and
typically result in negative outcomes.

Pot Withdrawal
Dr. Ryan Vandrey of
John’s Hopkins School of Medicine and colleagues compared symptoms of tobacco withdrawal with marijuana
withdrawal and to the withdrawal in study participants who used both
substances. The abstract of that study pointed out that “overall withdrawal
severity associated with cannabis alone and tobacco alone was of a similar
magnitude. Withdrawal during simultaneous cessation of both substances was more
severe than for each substance alone, but these differences were of short
duration and substantial individual differences were noted.” In working with
addictive behavior programs, some of the program attendees reported that
nicotine withdrawal was more of a problem during waking hours while marijuana
withdrawal was more of a problem during sleeping hours—because of an increase
in anxiety and insomnia (and sometimes in dreaming).

Illicit Drug Use Increasing
This week I’ll provide
some comments and resources for those who have asked about illicit drug use. According to
SAMHSA (Substance Abuse and Mental Health Services Administration) for 2014: 27.0
million people aged 12 or older used an illicit drug in the past 30 days, which
corresponds to about 1 in 10 Americans (10.2 %), higher than the percentage in
every year from 2002 through 2013. That included 22.2 million current marijuana
users aged 12 or older (can double their risk of being in a car accident);
473,000 young adults who used cocaine, including 29,000 who used crack (after just one use cocaine can rewire the brain and drastically affect
decision-making); and about 435,000 people aged 12 or older were current
heroin users (a dangerous and highly addictive opiod with no accepted medical
use in the USA). The National Survey on Drug
Use and Health (NSDUH) reported highest rates of dependence to lowest; the top
three listed: Heroin, Crack, and Marijuana.

Origin of Phrases, 5
1. The whole nine yards: American fighter
planes in WW2 had machine guns that were fed by a belt of cartridges. The
average plane held belts that were 27 feet (9 yards) long. If the pilot used up
all his ammo he was said to have given it the whole nine yards.
2. Buying
the farm: This is synonymous with dying. During WW1 soldiers were given life
insurance policies worth $5,000. This was about the price of an average farm so
if you died you ‘bought the farm’ for your survivors.
3. Passing the Buck / the buck stops here: Most men in the early
west carried a jack knife made by the Buck knife company. When playing poker it was common to place one of these Buck knives in front of the dealer so that
everyone knew who he was. When it was time for a new dealer the deck of cards
and the knife were given to the new dealer. If this person didn't want to deal
he would ‘pass the buck’ to the next player. If that player accepted then ‘the
buck stopped there.’

Brain-Immune Link, 2
The discovery of Immune System lymphatic
vessels in the brain—by researchers at the University of Virginia School of
Medicine—raises questions that now need answers, both
about the workings of the brain, the diseases that plague it, and the link between the brain and the immune system. Jonathan
Kipnis, professor in the Department of Neuroscience and
director of the Center for Brain Immunology and Glia at the University of Virginia, said, “In Alzheimer’s, there are accumulations of
big protein chunks in the brain. We think they may be accumulating in the brain
because they’re not being efficiently removed by these vessels.” And there is
an array of other neurological diseases, from autism to multiple sclerosis to be
reconsidered in light of the presence of something science did not know about or
even believe existed. Watch for more discoveries about PNI
(psychoneuroimmunology) and the close brain-body connection.

Brain-Immune Link Discovered
In what has been termed a “stunning discovery
that overturns decades of textbook teaching,” researchers at the University of
Virginia School of Medicine have found that the brain is directly connected to
the immune system by lymphatic vessels previously thought not to exist. According
to Jonathan Kipnis, a professor in the Department of Neuroscience and
director of the Center for Brain Immunology and Glia, “It
changes entirely the way we perceive the neuro-immune interaction. . .We
believe that for every neurological disease that has an immune component to it,
these vessels may play a major role.” The discovery was made possible by the
work of Antoine Louveau, a postdoctoral fellow in Kipnis’ lab. More tomorrow.

Zika and the Brain, 2
How do you get Zika?
This viral
disease is caused by the Zika virus that is transmitted by Aedes
mosquitoes that typically lay eggs in and near standing water in things like
buckets, bowls, animal dishes, flower pots and vases. Besides
standing water, rodents, birds and small mammals, may act as reservoirs. These mosquitoes are
aggressive daytime biters. They can also bite at night. Reportedly they prefer to
bite people, and live indoors and outdoors near people. Mosquitoes become
infected when they feed on a person already infected with the virus and they
then can spread the virus to other people through bites. A mother can pass the
Zika virus to her unborn child (although there are no reports to date of
transmission through breast milk). And there have been reports of infected
males passing the Zika virus to sexual partners through infected semen. Much
more information is available through the CDC Zika site.

Zika and the Brain
Perhaps recalling that I was once the Supervising PHN and
then acting director of a county health department and an Infection Control Preventionist
for several acute hospitals, I have been asked (among other questions), “What
do you think of mosquitoes?” My answer? I think mosquitoes are the ultimate in
bioterrorism, causing damage and death to millions the world over. They spread
any number of viruses and parasites and who knows what else, causing diseases
such as Malaria, Yellow Fever, Dengue, Zika, and Chikungunya. Zika is related
to Dengue, Yellow Fever, Japanese encephalitis, and West Nile viruses. Some recent studies are
linking the Zika virus to microcephaly (a smaller-than usual sized head in the
fetus of a pregnant woman who has the Zika virus). Thus, the suggestion that
women in areas where these mosquitos live should avoid getting pregnant because
of the risk of microcephaly and/or other birth defects to the developing fetus.

Origin of Phrases, 4
1. Log-book: An early way
to measure a ship’s progress was by casting overboard a wooden board known as
‘the log’ with a string attached to it. The rate at which the string was played
out as the ship moved away from the stationary log was measured by counting how
long it took between knots in the string, and a 'knot' came to used as the unit
of speed at sea. These measurements were transcribed into a ‘log-book.’
2.
Barge in: Heavy freight was moved along the Mississippi
in large barges pushed by steamboats. These were hard to control and would
sometimes swing into piers or other boats. People would say they ‘barged in.’
3.
A shot
of whiskey: In the old west a .45 cartridge for a six-gun cost 12 cents, so did
a glass of whiskey. If a cowhand was low on cash he would often give the
bartender a cartridge in exchange for a drink. This became known as a ‘shot’ of
whiskey.

Heart Em Energy, 2
Speaking of Em energy, you know I enjoy quotations, and
this one by William Blake is no exception. “Man’s perceptions are not bounded
by organs of perception. He perceives far more than sense (though ever so
acute) can discover.” So Blake must have been aware, at least at some level, of
the Em energy that we as human beings are always generating, releasing, and
picking up from others in the environment. In The
HeartMath Solution Doc Childre and Howard Martin pointed out that the heart has its
own independent nervous system with at least 40,000 neurons (as many as are
found in various subcortical sections of the brain) and there is a 2-way
nervous system relay between the brain and the heart. There are a few people in my life that I love to spend
time with because my brain and my heart ‘feel good around them.’ Marvelous!

Heart Em Energy
You may be familiar with the work being done at the
HeartMath Institute, where researchers have been studying the heart and its
electrical field for over two decades. I always pause whenever an email from
Sara Childre, President of HeartMath Institute (HMI) pops up in my in-box and
read what she has to say. Recently, one of her communications reminded me that “Even through the
brain is a principal energy force, it turns out the heart actually has an
electrical field estimated by HMI to be 60 times the amplitude of the brain.”
Many studies have shown that the electromagnetic energy or Em energy that is
generated by neurons in your brain and heart can be detected by another person
in close proximity. Which, of course, always makes me want to be sure that the Em energy my
neurons are generating is positive. More tomorrow.

A Picture Worth 3200 Years
It has been said that a picture is worth a thousand words. How about a picture worth 3200 years? One of my strategies for age-proofing my brain while
growing older is to look for interesting pieces of information. I ran across
one the other day, the National Geographic Society always being a good source. Photographers
took and managed to take and piece together 126 photographs. This means that for
the first time ever there is a picture of ‘The President.’ No, not the US
president. Rather a giant sequoia that stands at 247 feet tall, is
estimated to be over 3,200 years old, and has been nicknamed ‘The President.’
The story of how they did it is amazing, too.

Struggling with Forgiveness?
Anger,
bitterness, hostility, and unforgiveness are hungry parasites that feed and
feed until there is nothing left for the brain or heart to eat. ¾Arlene
R. Taylor
So begins my mini-monograph on forgiveness. I’ve been
asked to speak about the brain and forgiveness a lot lately. Some have heard
about the work to Herbert Benson MD, internationally known cardiologist and
researcher. His studies have shown how critically important forgiveness is for
the health and wellbeing of the person doing the forgiving. You forgive for ‘your’
health and longevity, not for the one you are forgiving. This means that the
person you are forgiving need not even know he or she is being forgiven, need
not even be still alive. Once your brain ‘gets’ that forgiving yourself and
others is healthy selfishness, it makes it easier. It’s about you, not them. By
request I took the time to write out some of the information on forgiveness—the
URL is below. I encourage you to embrace forgiveness; it’s good medicine.

Origin of Phrases, 3
1.
Showboat: These were floating theatres built on a barge that was
pushed by a steamboat. These played small towns along the Mississippi River.
Unlike the boat shown in the movie ‘Showboat’ these did not have an engine.
They were gaudy and attention grabbing which is why we say someone who is being
the life of the party is ‘showboating.’
2.
Over a barrel: In the days before CPR a drowning victim would be
placed face down over a barrel and the barrel would be rolled back and forth in
an effort to empty the lungs of water. It was rarely effective. If you are over
a barrel you are in deep trouble.
3.
Hogwash: Steamboats carried both people and animals. Since pigs
smelled so bad they would be washed before being put on board. The mud and
other filth that was washed off was considered useless ‘hog wash.’

Two Goals at a Time, 2
When
humans pursue two goals A and B concurrently, a part of the brain known as the
medial prefrontal cortex (MFC) divides so that half of the region focuses on
one task and the other half on the other task. The anterior most part of the
frontal lobes enables you to switch back and forth between the two goals, i.e.
executing one goal while maintaining the other one on hold. This
inter-hemispheric division of labor explains why humans appear unable to
accurately carry out more than two tasks at one time. If you want to look at a
visual representation of how this works in the brain, I’ll include a URL below.
Credit for the representation goes to principle brain researcher: Etienne
Koechlin, INSERM-ENS, Paris, France.

Two At a Time for the Brain
Many people believe they can ‘multitask’
very efficiently. Those who do, may need to think again. Studies by researcher researcher Etienne Koechlin of the Université
Pierre et Marie Curie in Paris, France show that “… we can readily divide
tasking. We can cook, and at the same time talk on the phone, and switch back
and forth between these two activities. However, we cannot multitask with more
than two tasks.” According to Koechlin, the study results might also explain
why humans seem to have difficulty when decisions involve more than two
choices. When faced with three or more choices, subjects don't appear to
evaluate them rationally; they simply start discarding choices until they get
back to a binary choice. This is perhaps because your brain can't keep track of
the rewards involved with more than two choices.

Fiji Under the Sea
In actuality, I know very little about Fiji – although as I child I was
so curious about it and hoped I could go there one day. Well, next year I may get my wish as I have
been invited to present some brain-function seminars that. What fun! Opening my
email today I discovered that my friend and colleague, Dr. Banford, had send me
the URL for a YouTube presentation about life under the sea in Fiji. Just having
finished presenting three brain-function seminars I kicked off my shoes in my
hotel room and proceeded to watch the YouTube. Oh, My, Goodness. Most of the underwater
creatures I had never seen before and they were amazing. You may want to take a
few minutes and watch this . . . And, last but not least, Happy Birthday to my
friend and superb composer-pianist-organist, David H. Hegarty.
