Link between psychological stressors and stroke risk

From the American Heart Association:

Higher levels of stress, hostility and depressive symptoms are associated with significantly increased risk of stroke or transient ischemic attack (TIA) in middle-age and older adults, according to new research in the American Heart Association journal Stroke.

This research finding isn't new or news to those of us in the mental health community but whenever there's data to corroborate what is, at times, conventional wisdom, I like to take the time to post it. What was particularly telling from this study was that hostility was also found to be linked.

When I teach mindfulness, I tend to emphasize the connection I've found between judgemental thoughts and emotion, particularly anger. As we know, hostility is a type of anger, whether that be directed towards others or ourselves. As we strive to live more mindful lives, it's worth examining the connection between our judgements and our long-term emotional and physical health.

You've to move it move it.

My son has a birthday card he got from his grandparents. It's one of those annoying singing birthday cards that have no audio fidelity at all but makes a 4 year-old crack up. The song is I like to move it. (by a band I've never heard of called "Reel 2 Real".) Whatever the band's name is or the degree of annoyance of the song, it's a catchy tune and an apt title for this post. The NYT reports:

Each volunteer exercised for four months, while continuing to take an antidepressant. At the end of that time, according to the study published recently in The Journal of Clinical Psychiatry, 29.5 percent had achieved remission, “which is a very robust result,” Dr. Trivedi said, equal to or better than the remission rates achieved using drugs as a back-up treatment. “I think that our results indicate that exercise is a very valid treatment option” for people whose depression hasn’t yielded to S.S.R.I.’s, he said.

I like to think of early depression treatment as targeting one or more of the areas affected by Major Depressive Disorder:

  1. Cognitive
  2. Somatic (physical/energy levels)
  3. Sleep
  4. Emotional
  5. Motivational

There are others things that need to be targeted but the majority of patients in early treatment for depression have a lot of work to do one one or more of those areas and it's extremely relevant to their situation. It's nice to see something so clearly affected by depression, yet so incredibly simple to do, gets continued attention in the press and research literature.

 

The science of anger

Self-restraint can be hard to effectively manage. There's been an ongoing debate about the notion of catharthis and whether it works to help us relieve emotions or not, for example. A recent article in Wired.com discusses the issue a bit more:

My favorite experiment involved movies. Two hundred and thirty nine subjects were given a choice between a virtuous apple and a hedonistic chocolate bar. (A slim majority chose the apple.) Then, they were offered a selection of movies to watch, from Anger Management (an anger themed film) to Billy Madison (a non-anger themed film.) Interestingly, students were significantly more likely to choose the angry films if they’d first chosen the apple. And it wasn’t just films: another experiment found that people who exercised financial restraint – they chose a gift certificate for groceries over one for spa services – were more interested in looking at angry faces.

But just because practicing self-restraint can lead to some anger-related experiences, it doesn't mean that we should forgo self-restraint entirely. Over time, not succumbing to urges will weaken the power of those urges. The implication is that if we can practice self-restraint consistently, we'll be reducing how often we feel angry and/or seek out anger-related stimuli.

DBT again shown to be effective

The American Psychological Association highlights some key findings regarding the treatment of personality disorders. Help for personality disorders:

In a study comparing dialectical behavior therapy and traditional psychotherapy, women who underwent dialectical behavior therapy were more successful at reducing suicide attempts, self-mutilating and such self-damaging behaviors as gambling and substance abuse.

As we've known for a long time, DBT helps immensely when used to treat personality disorders. I'm always happy to see more research supporting its use. We, at Durham DBT, take pride in our training and our use of a comprehensive DBT model to help those with personality disorders, Borderline Personality Disorder, specifically, and people who are struggling with emotion generally. Treatment works.

Thinking faster

Training the brain through mindfulness practice is an essential part of Dialectical Behavior Therapy. We work on developing a way of sorting out what is important to attend to and what needs to be left out of awareness. It’s not ignoring information, but making quick decisions about where mental energy needs to be focused.

A recent study, described in the New York Times, highlights some of the differences between athletes and non-athletes in a decision making exercise:

They didn’t move faster,’ said Art Kramer, the director of the Beckman Institute and a leader in the study of exercise and cognition, who oversaw the research. “But it looks like they thought faster.”

The author, correctly, goes on to emphasize that athletes may not be better at making quick decisions because of their athletic participation but it could be that their participation in sports and their ability to make quick decisions are related to a 3rd factor. It may also be that there is a virtuous cycle between that unnamed 3rd factor and athletics:

Of course, it’s also possible that sports didn’t make the athletes better at information processing. Instead, they may have been blessed with naturally fine processing abilities and, as a result, became accomplished athletes. “I’d guess,” Dr. Kramer said, “that to some degree it’s both.” But, he added, the athletes handled the crossings better than the nonathletes, regardless of whether their sport required exquisite timing and tactical thinking — which strongly suggests, he said, that physical training does reshape the brain.

The take-home message for all of us non-athletes is that working on mental acuity exercises and being mindful while doing activities can help improve your ability to be mindful and effective in making decisions.

Sleep and health

When a client first gets started in therapy, we often try to “go back to basics.” That is, recalibrating those things that tend to get off center when things get hard:

  • sleep
  • exercise
  • eating
  • medication use

Specifically referred to as the “ABC Please” skills in DBT, we try to do what we can to reduce negative emotion[1], we try to re-implement those things that don’t take a lot time to do and provide a great deal of benefit over the near term. Sleep is one of those:

There’s a syndrome called sleep inertia which is the cognitive impairment, disorientation, and groggy feeling we experience when we first awake from sleep. Sleep inertia can negatively impact the brain’s ability to think clearly and our ability to function effectively in performing tasks right after we wake up (Donatelle, 2009). Just think about the challenge it takes to brush your teeth when you wake up after only four or five hours of sleep.

I’ve never heard of “sleep inertia” but I’m not a sleep guy. I just know that it’s important. The term makes conceptual sense, even if it’s just a fancy name for begin groggy.

The stages of sleep include: wakefulness, drowsiness, light sleep, and deeper sleep. It is in the deeper sleep phase where rapid eye movement (REM) sleep occurs. REM sleep is absolutely essential. In fact, missing REM sleep is responsible for our feeling groggy and sleep deprived (Donatelle, 2009).

I recommend that my patients get through at least 2 REM cycles of sleep/night in order to feel well rested. At the very least, make sure you get through at least one REM cycle. For most people, that’s about 4 hours or so.

There are so many little things that you can do to adjust your life to make it a bit better. None of them may be earth-shattering changes, but taken together, they can make a big difference.

Paying penance or distracting?

When reminded of an immoral deed, people are motivated to experience physical pain.


This is the opening line of the discussion section in a recent article published in Psychological Science. The hook is alluring, isn’t it? Thinking about times that you were “bad” makes you want to punish yourself. I was attracted to this article for review because of my interest in working with self-injurious patients. There are two predominant reasons people engage in self-injurious behavior (SIB):

1) He/She wants to regulate his/her emotions through distraction or 2) He/She wants to punish him/herself for some perceived wrong or defect.

As a starting point in understanding SIB, these two perspectives are helpful. They give us a framework to begin to explain possible motivations and the function of that particular SIB. In other words, how do we get those needs met without having to engage in SIB?

The Article

Getting back to the article, the authors engaged in a simple experimental manipulation in which participants were assigned to either the recall of “immoral”[1] interpersonal behavior or more generic interpersonal behavior. Participants rated their affect using the PANAS[2] and then engaged in the pain part of the study. Following the painful/non-painful experience, their level of “guilt” was measured by completing the PANAS again.[3]

The researchers found that participants in the guilt inducing/pain condition expressed lower levels of guilty feelings after the manipulation, leading them to conclude that the painful experience caused a drop in guilt ratings.[4]

The participants in the guilt/pain condition also perceived more physical pain during the manipulation than those in the non-guilt/pain condition.[5]

Reading the Tea Leaves

The authors go on to claim that the motivation for causing pain is to reduce guilt. I believe they’ve got their conclusions backwards. Guilt is reduced because of the pain, not the other way around. Getting into divining motivation is a specious area at best. Unfortunately, I don’t see how the results of their study supports that explanation. This reading of the data is basically saying that the second of my two reasons for SIB listed above is the reason for engaging in the behavior. However, I believe that emotion regulation aspect of painful experience is not to be understated.

Pain as Emotion Regulation

The explanation of this article is a long way around to talk about my favorite therapeutic technique — mindfulness. Specifically, using mindfulness as a way to stop thinking about particular experiences can help reduce the intensity of those thoughts and the subsequent emotion. Rumination on particular misdeeds fires off a host of strong emotions and breaking into that ruminative cycle prevents continued emotional experience. In this particular case, the ice was an unavoidable mental focus and we can see support for this supposition in the subjective experience of the pain.

To further draw out the supposition, without too much of a stretch, we can say that people actively avoid thinking about times they did something “wrong”. When the participants were presented with a mental “out”, they took it. Ice is painful and it’s relatively easy to focus on pain. Focus on the physical pain increases the subjective experience of the pain. Two conclusions can be drawn from this:

  • For those who were suffering from emotional pain as a result of the manipulation — those in the “guilt” condition — this physical pain was deemed to be less intense, so they focused on the ice.
  • For those in the non-guilt — those without emotional pain — the physical pain was more uncomfortable to they focused away from it, leading to subjectively less pain.

Mindfulness as Emotion Regulation

The revealing thing about this article is that a mindful experience can be emotionally regulating. In DBT, we talk about using ice as a distress tolerance skill. This research, coming from a non-DBT perspective, corroborates that belief. I don’t believe that you necessarily need to subject yourself to physical pain to get the same sense of relief — you don’t need to punish yourself to feel better, at least all the time — you just need to be able to mindfully turn away from your rumination.

The process isn’t as easy as it sounds since being able to turn away from your ruminative thoughts is work. Our minds have a tendency to stick to things that we least like them to stick to. Cultivating mental control through regular practice and developing a sense of forgiveness and genuine caring for yourself can help. You should not let yourself violate your values if you can avoid it, but if you have, make up for it and then move on.

Footnotes

[1] The authors defined “immoral” behavior as ostracizing someone. I’d buy that as a particularly embarrassing experience.

[2] The PANAS is a well-validated measure of affect. I’m not sure how well it measures guilt, but since this is a peer-reviewed article, I’m going to give the authors the benefit of the doubt.

[3]This type of within subject/repeated measure design is common in psychological research. It’s designed to measure change across time or via experimental manipulation and has much theoretical support. It’s an especially powerful design because each subject is his/her own control.

[4]Given that this was an experimental design, causal conclusions are warranted.

[5]This finding, I believe, is particularly salient.

More disheartening treatment utilization news

The NIMH reports on a recent study released in Archives of General Psychiatry:

About 3 percent of U.S. adolescents are affected by an eating disorder, but most do not receive treatment for their specific eating condition, according to an NIMH-funded study published online ahead of print March 7, 2011, in the Archives of General Psychiatry.

While the data on the success of treatment for an eating disorder in adolescence is unclear, the fact that most of anyone suffering from a major mental disorder isn't getting treatment is quite disturbing. Given the extremely powerful reinforcement contingencies in place for an eating disorder, earlier intervention is needed.

Being an expert isn't all that great.

For a long time, psychologists have known about the heuristics people use to make sense of their worlds. One of the better known is the idea of chunking information into to smaller, more manageable pieces of information. Try memorizing this number (no cheating!):

8 2 8 4 3 2 5 7 6 1

Some of the more astute among you might notice that's a 10-digit number with an area code somewhere in the vicinity of Asheville, NC (a beautiful place to visit if you ever get a chance!). So, you're probably ahead of the game.

We memorize a new 10-digit phone number by making chunks of 3, 3, and 4. That translates into a mental load of just 3 things you need to remember rather than the 10-digits you might try to memorize. This is great for information that we're familiar with and translates into useful mechanisms for learning.

Wired describes the phenomenon in other terms:

[T]hat talent wasn’t about memory – it was about perception. The grandmasters didn’t remember the board better than amateurs. Rather, they saw the board better, instantly translating the thirty-two chess pieces into a set of meaningful patterns. They didn’t focus on the white bishop or the black pawn, but instead grouped the board into larger strategies and structures, such as the French Defense or the Reti Opening.

I'm an avid NPR listener and everyday at 9:00 AM, they have the BBC World Service's broadcast. During this program, the host often calls for feedback from listeners and announces a string of numbers that I just can't get my head around. It's because they chunk the information differently. The host announces the numbers in a series of 2 digits at a time for that same 10-digit length phone number. But my brain can't handle the different presentation.

Wired goes on to say:

The problem with our cognitive chunks is that they’re fully formed – an inflexible pattern we impose on the world – which means they tend to be resistant to sudden changes, such as a street detour in central London. They also are a practiced habit, and so we tend to rely on them even when they might not be applicable. (A chess grandmaster has to be careful about applying his chess chunks to checkers.)

So, next time you're having a hard time committing something to memory, try thinking about it as a naive person. Use what Suzuki calls Beginner's Mind.

On avatars and anxiety

I've long been fascinated with the idea of using computers to deliver treatments. I've always been described as a gearhound and if you were to see my office, you'd understand why. While it may seem counter-intuitive that a psychologist would like to see computers doing more of my job, I think actual people will continue to have a place in treatment.

The New York Times reports on using computers to aid in anxiety treatment:

The anxiety rose in his throat — What if I’m not making sense? What if I’m asked questions I can’t answer? — but subsided as his therapist, observing in the background, reminded him that the audience’s reaction might have nothing to do with him. And if a question stumped him, he could just say so: no one knows everything.

There's something unique about anxiety disorders when they are found in isolation, as they are in studies such as these. Specifically, the typical response and thought patterns found are visceral and fairly predictable. These thoughts tend to be less rational and thought-out than our more mature thoughts might be, making them relatively1 easy to refute. Similarly, the typical physiological response is pretty clear to the person suffering the anxiety, again making it an easier target to address, perhaps using mindfulness techniques to enhance your interoceptive awareness.

That said, there are a number of situations in which computer-aided psychotherapy for anxiety might not be effective. Even in the above linked article, there was a psychologist coach present for the role-playing event. The bottom-line is that we are still many years away from being able to get away from actual trained clinicians for the treatment of many of our mental disorders. And don't you think it'll still nice to be able to talk to a real person from time to time, anyway?


  1. I don't think that they are easy by any real stretch of the imagination. As far as psychotherapy goes, though, restructuring the cognitive distortions associated with a non-comorbid anxiety disorder is relatively easy. ↩
