June 18, 2008Depression Linked To Absolutely Everything, Solutions ElusiveA new study is out today in JAMA asserting a link between type 2 diabetes and depression and vice-versa. The study now joins reams of studies in recent years--many of them by non-psychiatrists, just to be clear--that link depression with seemingly every human malady and shortcoming. Heart disease, cancer, obesity, chronic pain, racism, poverty, smoking and so on have all been tied in with depression, locked in the kind of bio-psychological feedback loop that has doctors calling for depression screening and the inevitable push for treatment with anti-depressants (which themselves have been linked with diabetes causation in some studies just to make things even more confusing) and me scratching my head over what it all means. Because it does all mean something. And maybe nothing all at once. I'm not trying to minimize these kids of well-meaning studies, but is it possible in this day and age of doctors micro-managing human existence and marching us all off to our neighborhood pharmacies, allegedly to make us feel better, to say that when people are sick, especially with chronic illnesses, that there's a likelihood of some depressive symptoms because that's just the nature of life and the nature of life is kind of depressing? Especially when you are sick. In the diabetes study: "People being treated for Type 2 diabetes, the most common form, were 52 percent more likely to develop depression than those without the disease.... The basic findings were that 14.4 percent of people with type 2 diabetes had some symptoms of depression while 11.7 percent of people in the study without diabetes had some depressive symptoms (and that rate for the latter group is well above the generally accepted 6.7 percent NIMH number for depression in the general population). Whether the diabetes was driving the depression or vice versa isn't clear (I'm sure there's data pointing in both directions), but confoundingly only 7.4 percent of study patients who had untreated diabetes had symptoms of depression. That's roughly half the rate of depression in people being treated for diabetes, which kind of makes you wonder a bit about the nature of diabetes treatment and about the power of psychological suggestion of treated versus untreated states. That's not an argument against diabetes treatment of any kind. I'm just pointing out that not all of the pieces fit as conveniently as the many news accounts of this study would lead you to believe. But let's assume for a moment that all of these depression linkage studies are rock-solid truth. Is the implication that anyone with diabetes or heart disease must also get an anti-depressant? Would that make sense for a treatment modality that works about 30 percent of the time and comes with the potential for a host of gnarly side effects? What about with chronic pain, where I'd judge the depression relationship to be very strong? Do you treat the pain or the depression? The way the DEA and some state health departments have gone after the use of painkillers now means that many, many people with chronic pain are being forced into using anti-depressants to treat the underlying pain (and some anti-depressants are approved for various pain indications) with very mixed results both in treating pain and depression. Is this a good thing for us as a culture? I don't pretend to have the wisdom to sort these kinds of questions out beyond observing that maybe patients should be fully informed of what they are up against and what the pros and cons are of anti-depressant treatment, leaving them to arrive at their own answers for how to treat their own bodies and moods. This is America after all. And, as far as wisdom goes, I find studies such as the JAMA one to be singularly lacking in wisdom, despite their very interesting and very conflicting data. Onward marches medical science. Posted by Philip Dawdy at June 18, 2008 12:03 AM

Hmm some people need a Statistics 101 refresher. Let's take type 2 diabetes and depression for example. Correlation is not causation. Have they done the appropriate controls and regression testing for other variables? I can immediately think of two potential explanations that make these epiphenomenal - age and social class. Type 2 diabetes is more common in the poor. As is depression. Type 2 diabetes is more common in seniors. As is depression. I'm sure there are lots more. So you'd need to do a check on EVERY such variable before making any claim (this is why proper research takes so long folks, all that statistical testing). Some of these people whose announcements you are reporting on here need to re-read Huff's "How to lie with statistics". Anyway yeah I agree with you . Did you know grey hair was lethal? Some years after their hair went grey, more years in some cases than others, all grey haired people died! Let's distributed some Grecian Formula and we'll all live forever... Posted by: DeeDee Ramona at June 18, 2008 02:11 AMPerhaps it's only a question of semantics. And here I thought getting diagnosed with type 2 diabetes was supposed to make people happy (or to use the clinical term for that pathology, hypomanic). You know they've also done studies that indicate that people become depressed when a loved one dies. What's next? Thank goodness for all of this research. Posted by: Sally at June 18, 2008 03:43 AMPhilip, studies like these make me go nuts. On a related note, remember the study that showed than antidepressants should be given as prophylactic treatment for stroke? Uh, if you have a medical condition that causes you to lose your cognitive ability. of course, you are doing to be depressed. Here is a novel idea. Instead of using antidepressants, what about engaging people in aggressive non medicine related remediations that would enable them to get the most out life. For the person with diabetes, teach them how it is possible with adequate monitoring of necessary things specific to diabetes, that they can lead a normal life. It might do wonders for their depression. Also, provide role models who have succeeded in spite of their illness. Apparently, there was an article in the Wall Street Journal about a guy with brain cancer? that affected a part of his brain who learned how to expertly manage his portfolio in spite of several cognitive difficulties who did very well. Again, this would do alot more for the depression than an antidepressant. The problem with my suggestions is they take more time than just handing a pill. Sadly, in our microwave society, professionals care more about the quick fix than they do if it it really words. AA Being sick is definitely depressing and enough to set things off, no doubt... I do though, also think that stress of any kind, and depression is a kind of stress does effect the body. But I share your opinion that these studies are rather without value. Making a choice to live a sane, healthy life is all I take from it. If you're making lifestyle choices to be healthy, mentally and physically, in spite of what the condition of your current health is, you will feel empowered and therefore better. Posted by: Gianna at June 18, 2008 06:12 AMI also believe these studies go nowhere. Of course someone who has one or more of these conditions is more likely to be depressed. Depressions leads to health problems and health problems lead to depression. That's a no brainer. As you imply the real objective of these studies is to get people on antidepressants and many readers here know that that is unlikely to do any good at all other than perhaps a short term burst of a chemical induced high. In the long run antidepressants will worsen each and every one of these conditions, create more health problems of all sorts and exacerbate depression too. Great for building business in the medical and pharmaceutical industries but crappy for the patient. Posted by: Sara at June 18, 2008 08:22 AMDon't these people have any idea of the mess they are creating? I wonder what Einstein would say. PS Me again... again? I really doubt there is a giant conspiracy afoot here. Imagine that you have just been diagnosed with a chronic illness for which there is no cure, which could result in serious complications (including death) if left untreated, which inflates your risk of developing other chronic conditions, which may require you to make significant changes in your lifestyle, and which will necessitate your monitoring various aspects of your physical functioning several times a day, every day, for the rest of your life. Sounds pretty overwhelming, doesn't it? Enough, maybe, to make you feel sad and helpless for a little while, as you are forced to adjust to new knowledge about yourself and your future? "People being treated for Type 2 diabetes, the most common form, were 52 percent more likely to develop depression than those without the disease...." I think "develop depression" should actually read here "be diagnosed as having depression." It's a subtle distinction but the implications are huge. "Doctors may want to consider screening those with diabetes for depression because it may affect how well patients follow recommendations and their risk of developing complications of the disease, researchers said." Intriguing. Would depressed patients be more or less likely to follow correct diabetes treatment? And why? Anyway, these studies are really boring because none of them address the problem: the initial categories (DSM labels) are entirely subjective. Posted by: Francesca Allan at June 18, 2008 08:27 PMThe study is interesting in that it notes that people who have their diabetes 2 undiagnosed are not labeled as depressed. So what is causing these subjects to get the depression label is being diagnosed with diabetes (or I admit it could be that these same people haven't been to a doctor in a while). Could it be that people who are more open, trusting and forthcoming about their concerns regarding being diagnosed with diabetes are more likely to be diagnosed as depressed? People who don't follow their diabetes doctors recommendation or who want to try alternative treatment for diabetes are more likely to be punitively labeled as depressed because their doctors perceive them as non compliant? Could it be that some people amplify their reports of depression so they can get diagnosed as depressed and get the happy pill? Who knows, but it is odd that what the study really says is that being treated for diabetes causes depression and as pointed out, the study is probably so flawed as to meaningless for other reasons than that depression is not a medical disease. And how do ssri's affect the appetite, metabolism, etc? How does insulin affect mood? Are "they" going to recommend diabetics take zyprexa if we move to the anti-psychotics for everything model? It seems similar to the GMA report about becoming poor causing suicide,the problems are societal...poor diet causes diabetes, poverty causes poor diet, poor diet makes you feel good in the short run and then your body starts to die. I can see how finding out such a thing might cause a little unhappiness. The solution would seem to be us folks improving our society so that we have less poverty - figuring out how to do so is so hard even I long for a bit of paxil or a seroquel hit (just for a second mind you). Posted by: Sally at June 19, 2008 02:32 AM Gerbil, I posted before without reading your post. You make some good points. I wonder what the studiers mean by "depression." I doubt it's what you are describing, true clinical depression, which I don't believe is a medical disease, but is a real if rare condition. Also, on the positive side, this study does tend to indicate that depression is not a medical disease caused by a chemical imbalance in the brain but an understandable human response to life. I wonder if people who are not actually diabetic meet the criteria to be labeled as depressed if they are wrongly diagnosed as diabetic but even though big pharma is unethical enough to do such a study, there's no money in it. Us humans seem fairly good at gathering information, it's figuring out what to do with it that we're not good at. Posted by: Sally at June 19, 2008 03:13 AMI know this is a serious post and subject, but that headline made me laugh. it sounds like something out of the Onion. Posted by: molly g at June 19, 2008 10:18 AM"But my grandpa kept a positive attitude, and my dad keeps one as well." There you are!
Ana, I most certainly did not (nor would I ever) say this: ""But my grandpa kept a positive attitude, and my dad keeps one as well" so please don't attribute it to me. Thanks. Francesca Posted by: Francesca Allan at June 19, 2008 08:51 PMI'm very sorry Francesca. I agree with Molly Philip, I had a smile when I saw the title, it does sound Onionesque. How about this as a title: Major Flaw in Science Revealed! Today evidence was revealed that overwhelmingly indicates a critical flaw that has cropped into scientific research. A widening trend of complete lack of common sense pervades modern sciences today. Causes are unknown at this time and solutions so far have not only been elusive, they are not even under discussion. On a more serious note about the painkillers. I have noticed this trend and it bugs me. Although I have had some strong feelings and opinions largely against psychiatric medications I am in no way anti drug. Back when I used to suicidally depressed and I hated myself I did some stupid things to my body. I am paying for it now, in my 30s for the mistakes of my teens and early 20s. I have spinal pain, soft tissue damage in my neck, some disk degeneration and tension that has been with me for years. Fortunately the practice of tai chi and chi gung keeps me not only functionally well but the improved function and mobility helps ward off the specter of depression born of the strain of enduring malfunction in your body that never quite goes away. On occasion I have a neurological storm for lack of a better word. My nerves and muscles seize up and I have some strange symptoms similar to palsy. Tai chi always fixes it every time but sometimes it happens in the night. I wake up spasming, in pain, feeling slow and rusty and 1000 years old. It is hard to get moving. Codeine owns every pain med I have ever tried. Codeine combined with a muscle relaxant like Flexaril gets me able to start my physical therapies. On those days I am grateful for having pills rather the going through the hassle of brewing opium tea which would be my only solution for an opioid based painkiller aside from taking heroin if codeine was pushed off the market. No way in hell I would take an SSRI or any other of the garbage meds they are churning out these days. In honor of the Onion and Philip's piece today I wrote my own post called, 'New study reveals strong links between depression and being alive.' :) good one jane. since a few have brought this up, the headline was a small attempt at humor but was also getting at my frustration with seeing study after study linking depression with utterly everything. it's gotten a wee bit excessive out there.
