Panic Attacks and CO2

CO2 is heavier than normal air and so will tend to sit at the bottom of your lungs unless you exhale it.

CO2 is heavier than normal air and so will tend to sit at the bottom of your lungs unless you exhale it.

John Wemmie and Michael Welsh of the University of Iowa, Iowa City, reported in the November 25, 2009 issue of the journal Cell, a Cell Press publication, that they have discovered a chemical sensor for carbon dioxide deep in the brain’s emotional center – the amygdala. This part of the brain, when it senses an acidic condition (ph) created by higher levels of CO2 in the body, triggers fight-or-flight behaviors we label panic attacks.

I’ve discussed before in this blog the impact of chemistry, particularly CO2 levels in the body on mood and behavior. This is not a new concept – it’s been known for at least a century (the Chinese knew it millenia ago) that chemical imbalances in the body affect behavior.

If you’re experiencing panic attacks fairly often, it could be that your amygdala is hypersensitive to CO2 levels. You may need to breathe differently to expel excess CO2 and increase the oxygen levels in your body.

Are Killer Repressed Memories a Myth?

A percentage of veterans (and by extension, some civilians) who have experienced traumatic events have a built-in coping mechanism that appears to repress traumatic memories in order to make life more satisfying and livable. And the strategy works well for them!

A percentage of veterans (and by extension, some civilians) who have experienced traumatic events have a built-in coping mechanism that appears to repress traumatic memories in order to make life more satisfying and livable. And the strategy works well for them!

“Going back to the days of Sigmund Freud, psychiatrists and mental health experts have suggested that repression of traumatic memories could lead to health problems. Yet we have found little evidence that repression had an adverse health impact on combat veterans exposed to psychological trauma many years later.”

Joseph Boscarino, Ph.D. and Tulane University investigator Charles Figley, Ph.D., have been studying the effects of repressed memories in Vietnam war and other war veterans to help understand the relationship between repressed memories and physical ailment and longevity.

For years I had worked under the belief that horrific traumatic experiences should “come out” to be resolved or relieved of their emotional charge – and that suppressing those memories was tantamount to denial – leading to terrible life consequences. I’ve worked with hundreds of clients, many of whom were veterans. For those who chose to disclose their traumatic emotional baggage, swift release of the psychic energy often produced a noticeable increased sense of well-being and life satisfaction – that lasted.

However, according to Boscarino and Figley, a percentage of veterans (and by extension, some civilians) who have experienced traumatic events have a built-in coping mechanism that appears to repress traumatic memories in order to make life more satisfying and livable. And the strategy works well for them!

In these cases, “Repression is a self-regulator and a method of memory management,” Dr. Figley said. “In other words, ‘keeping your stressful memories inside or it will kill you’ is a myth.”

To both practitioner and veteran, I would say – “If what you are doing is working well for you, no need to ‘rock the boat’ for the sake of therapy.” Like my old pappy used to say, “If it ain’t broke – don’t fix it!”

To that I would add – just because you experienced traumatic events does not necessarily mean you need therapy to “resolve your issue” or that you must have repressed memories that will affect you physically if not properly dealt with – usually by expressing them. Maybe all you need to do is continue to do what you’re doing now. Sometimes the hunt for repressed memories itself is more traumatic than the memories sought after – and can cause more psychological damage than repressing the memories.

However (and this is important) – if someone close to you suggests therapy, take them up on the idea. And if you suddenly find yourself acting out for no reason whatsoever – like losing your temper when your wife tells you she’s going to brew another cup of coffee or sit in a different chair – or maybe you start losing sleep at night due to recurring nightmares – consider therapy to relieve you of some suppressed emotional charge. The investment may just make the difference between “just getting by” emotionally and loving and living your life to the fullest.

Resilience – Evolutionary Advantage

Although I sprayed them every year they'd just come back stronger. They had become resilient.

Although I sprayed them every year they’d just come back stronger. They had become resilient.

There is a spot in our backyard garden where the same weeds pop up every spring – and which I spray each spring. Over time, the spray seems to be lessening its effect on them and now, the weeds simply cannot be killed using those sprays I’ve used before – they have survived and learned to be resilient.

For years I’ve believed that victimhood is the key to therapeutic inaction and failure. Clients who believe they are the victim of abuse feel powerless and helpless against the intense feelings that boil within them. “I can’t help it – I was beaten as a child. It’s DADDY’S fault I’m fat!”

What if you were to look at yourself instead as a survivor imbued with a strength called resilience? Rather than feeling helpless and hopeless, might you feel more empowered? And what if you were to learn that by putting your strength to work for you, you might actually make your life work better? What if you considered resilience an evolutionary gift rather than a problem needing correction?

Adversity’s Silver Lining

A little trauma actually strengthens your resilience.

A little trauma actually strengthens your resilience.

Mark D. Seery of the University at Buffalo published a paper on the psychological effects of adversity vs resilience. He concludes that a little adversity is actually good for you. But, how much is “too much” adversity depends on each person’s resilience. Many studies have shown that traumatic events can cause long-lasting psychological damage.

The common wisdom is “That which doesn’t kill you makes you stronger” – which is not supported by scientific evidence. Quite the contrary, most evidence points to the opposite – that which doesn’t kill you makes you weaker, at least psychologically.

However, Seery contends that a little trauma actually strengthens your resilience – a bit like exercise traumatizes yet strengthens muscles. Just like in the case of strengthening muscles by traumatizing them (to build muscle, one must damage muscle cells a little), a few traumatizing events in one’s lifetime can strengthen their resilience after future traumas.

Homeless Vets?

Veterans make up an inordinate percentage of the homeless in America.

Veterans make up an inordinate percentage of the homeless in America.

About 25 percent of homeless Americans are veterans-131,000 according to VA statistics-and more than 75 percent have a mental disorder, often PTSD. The National Coalition for Homeless Veterans has noted that Iraq veterans are already beginning to show up in that population.

Why the disproportionate number of veterans? (according to the Hoover Institute, about 8% of the US population are veterans)

The answer is complex, but I believe it is because of mental problems associated with their service time. PTSD being the most widely diagnosed condition.

I applaud the Defense Department’s efforts to provide treatment to veterans, but it seems that whatever treatment they are receiving is not getting them out of homeless shelters and back into productive lives.

Alternative healing methods have been tested in some VA hospitals, but I think the general bias against such treatments by the established medical community makes testing difficult and results ambiguous – while at the same time, medical and surgical procedures get passed with barely a blink. For example, Walter Reed Hospital published case reports detailing the successful treatment of combat-related post-traumatic stress disorder with a stellate ganglion block. Never mind that only TWO (count them – 2) subjects were involved in the testing.
