Tips on Anxiety Management

The Atlantic this week has an article entitled Surviving Uncertainty: A Few Tips by Lane Wallace.

As part of her credentials on this matter, she notes that:

“I’ve flown small aircraft on five continents. I’ve been stranded alone on a glacier in shorts and tennis shoes. I’ve found myself in the middle of rapidly destabilizing situations in African countries.”

She finds it helpful to

  • Focus on the present.
  • Keep perspective. Ask yourself, “what’s the worst thing that happens here?”
  • Separate what you can’t control from what you can, and then focus on taking action on those items you can control.
  • Learn to prioritize what’s essential, and loadshed everything else.

The Emotional Costs of Inequality

The Globe and Mail reviewed “The Spirit Level: Why More Equal Societies Almost Always Do Better,” by Richard Wilkinson and Kate Pickett, Allen Lane.

The reviewers write that:
“This is the authors’ “big idea”: People’s health depends on the quality of their social relationships, and the most important determinant of the quality of social relationships is the level of inequality.”

The book argues that as inequality increases so, too, does infant mortality, illiteracy, obesity, mental illness, incarceration, homicide, drug use and teenage pregnancy. Life expectancy decreases where inequality rises.

It’s well worth the time to read the article.

Map of Stress Across America

The Associated Press has an interactive map of the US broken down by counties of economic stress factors. It measures unemployment, foreclosure and bankruptcy.

A stress level of zero is best and 100 is worst.

For instance, here in Providence County, the stress level is 13.74 which is double the rate from a year ago.

Detroit’s level is 19.59.

Perhaps surprisingly, Jefferson Parish, Louisiana which was hit hard by Hurricane Katrina is only 5.84.

And the stress levels for Orlando, Florida have nearly tripled in the past year. Mickey and Minnie have their work cut of for them to entertain and soothe those Floridians.

Controversy About PTSD

Bob Herbert, in today’s NY Times, writes: “I couldn’t have been less surprised to read last week that an American G.I. had been charged with gunning down five of his fellow service members in Iraq.”

He goes on to say that “Recent attempts by the military to deal with some of the most egregious aspects of its deployment policies have amounted to much too little, much too late. The RAND study found that approximately 300,000 men and women who had served in Iraq and Afghanistan were already suffering from P.T.S.D. or major depression. That’s nearly one in every five returning veterans.”

His conclusion is that “We’re brutally and cold-bloodedly sacrificing the psychological well-being of these men and women, which should be a scandal.”

That is a scathing review of the current treatment of America’s service personnel.

On the other hand, Scientific American ran a lengthy article, Soldiers’ Stress: What Doctors Get Wrong about PTSD. The ‘key concept’ of this author’s position is that “The syndrome of post-traumatic stress disorder (PTSD) is under fire because its defining criteria are too broad, leading to rampant overdiagnosis.”

The author, David Dobbs, writes in his blog, Neuron Culture that:
“We are likely overdiagnosing PTSD in veterans by some 300 to 400%….the arcane disability system at the VA so discourages recovery that those receiving VA treatment — which is roughly similar to treatments that cure 2/3 of civilian patients — show no treatment effect at all. They’re no more likely to get better than are vets with PTSD not getting treatment.”

If the system is so broken and resistant, then one would assume that persons or groups, for their own benefit, maintain the current system instead of adopting a better alternative.

I suppose that it is possible that some in the VA benefit from the current model and would resist change to whatever might be a more effective model.

However, Dobbs finds that the country as a whole is invested in maintaining what he calls an “arcane disability system.”

Dobbs asserts that “war… might not be as scarring as we like to think it is….American culture seems to have a deep investment in the the picture of war as irredeemably toxic, and in its experience as incurably damaging.”

The structure of Dobbs argument runs similar to (but not as far as) Thomas Szasz or those in the anti-psychiatry movement. According to Wikipedia, Szasz finds that “people with mental illness have a “fake disease,” and these “scientific categories” are in fact used for power controls. Schizophrenia is “the sacred symbol of psychiatry” and, according to Szasz, is not really an illness. To be a true disease, the entity must somehow be capable of being approached, measured, or tested in scientific fashion.”

Hence there is a lot of emphasis on refining the criteria for PTSD and being able to objectively identify and measure the disorder in the brain. As Dobbs writes: “To make the diagnosis of PTSD more rigorous, some have suggested that blood chemistry, brain imaging or other tests might be able to detect physiological signatures of the disorder.”

And there is some progress being made in that arena. For instance, Medical News Today reported on recent research using functional magnetic resonance imaging scans (fMRI) that “found marked differences between the two groups in an area of the brain governing the sense of self. When the soldiers were shown the combat photos, this area, found in the medial prefrontal cortex, lit up remarkably in the PTSD group, but very little in the non-PTSD group.”

To give him his due, Dobbs does not find PTSD to be a “fake” disease. He concludes his blog entry with: “PTSD exists. Where it exists we must treat it. But our cultural obsession with PTSD has magnified, replicated, and finally perhaps become the thing itself — a prolonged failure to contextualize and accept our own collective aggression. It may be our own postwar neurosis.”

We have now gone from Herbert’s moral outrage at the lack of proper care and concern for veterans to Dobbs’ view that PTSD cases are 300-400% overly diagnosed and then for a quick stroll through metapsychiatric and cultural analysis.

Let’s return to the subject that is of real interest here: those who suffer from the psychological distress called PTSD.

The Canadian Journal of Psychiatry published a piece by Brunet, Akerib and Birmes titled: “Don’t Throw Out the Baby With the Bath Water” in 2007. The authors argue that:
“If we consider the evolution in the field of trauma research, there are at least 2 major tendencies: on the one hand, the criteria for diagnosing PTSD have become stricter, while, on the other hand, our ability to detect and correctly assess trauma exposure and PTSD has improved, thereby leading to the identification of new, previously undiagnosed cases. The net result of these 2 tendencies is a remarkably stable rate of PTSD in the epidemiologic surveys of the last decade.”

There are, then, real persons with PTSD, whether due to rape in the US or witnessing battle in Afghanistan, suffering from real emotional pain and cognitive limitations. We should get to the heart of the matter and figure out the best means of treating the illness and the best way to finance that treatment. Let’s not get side-tracked by fMRI results and whether or not America has a guilty conscience and so has made war out to be a scarring experience.

As Brunet, Akerib and Birmes write:
“the public debate and increased awareness about the hidden human and financial costs of traumatogenic events such as warfare, rape, and child abuse—to name just a few—must continue for the good of society.”

Depression and the Thyroid

In a reverse of what I thought I have clinically seen, a recent prospective study finds that low thyroid functioning is not associated with depression. In fact, they found the opposite to be true: a high thyroid function is associated with depression.

Evidently, I was not alone in thinking that low thyroid levels are associated with depression. The study’s authors write that: “Medical guidelines for clinical practice, produced by the American Association of Clinical Endocrinologists, state that ‘the diagnosis of subclinical or clinical hypothyroidism must be considered in every patient with depression.’”

The study, Thyroid Function and the Natural History of Depression: Findings From the Caerphilly Prospective Study (CaPS) and a Meta-analysis, by Williams, Harris, Dayan, et. al., was published on 05/12/2009 in Clinical Endocrinology. Unfortunately, I cannot give you a link because this comes from a subscription service via Medscape. But you can register for this service here.

Here’s a brief summary.

The authors undertook a

    “prospective cohort study of 2269 middle aged men (45–59 years) with thyroid function (total T4 only, TSH unavailable) measured between 1979 and 1983 and with repeat measures of minor psychiatric morbidity (GHQ-30) over a mean of 12·3 years follow-up. We also undertook a systematic review and meta-analysis of population-based studies examining thyroid function and mood.”

Their conclusion is that:

    “we find no evidence…that low thyroid function is associated with depression over the life course. In contrast, we provide evidence…that high normal thyroid function (lower TSH and higher T4) is associated with depression.”

In this case at least, anecdotal clinical evidence was turned upside down.

Kava for Anxiety?

Yesterday, May 11, The University of Queensland in Australia, announced results of research into the safety and effectiveness of kava for treating anxiety.
kava
Wikipedia tells us that:

  1. Kava (Piper methysticum) (Piper Latin for “pepper”, methysticum Greek for “intoxicating”) is an ancient crop of the western Pacific. Other names for kava include ?awa (Hawaii), ‘ava (Samoa), yaqona (Fiji), and sakau (Pohnpei). The word kava is used to refer both to the plant and the beverage produced from its roots. Kava is a tranquilizer primarily consumed to relax without disrupting mental clarity. Its active ingredients are called kavalactones. In some parts of the Western World, kava extract is marketed as herbal medicine against stress, insomnia, and anxiety.

There have been some concerns about the safety of kava and some countries have banned it’s use or sale. Makaira’s Kava Kava Blog gives details about the legal status of kava in various countries.

Back to the recent research, the researchers in Australia found that

  • The aqueous Kava preparation produced significant anxiolytic and antidepressant activity and raised no safety concerns at the dose and duration studied. Kava appears equally effective in cases where anxiety is accompanied by depression. This should encourage further study and consideration of globally reintroducing aqueous rootstock extracts of Kava for the management of anxiety.

The emphasis on “aqueous preparation” is due to concerns that other means of making the substance, chiefly ethanol and acetone extracts, may lead to liver damage.

I have no previous direct or indirect knowledge about kava and so this information is posted chiefly as a topic to be watched for further developments and research.
