Deep Brain Stimulation as Depression Treatment 273

Posted by samzenpus from the there's-something-wrong-with-my-brain dept.
Neopallium writes "Medtronic, today announced its intentions to pursue a major clinical trial of the company's deep brain stimulation (DBS) technology in the treatment of severe and intractable depression, a disabling form of the psychiatric disorder affecting millions of people worldwide. "While not a cure, DBS has allowed these patients to return to much more functional and happy lives," said Dr. Rezai, who represented an international working group of physicians that has been studying the application of DBS therapy in the treatment of intractable depression and OCD in collaboration with Medtronic."

      I wish it was as simple as that. It would sure beat what I have to do now, which is sprinkle a layer of espresso-grind coffee into my shoes, score the bottoms of my feet with a razor blade, and then tie my shoelaces really tight, so as not to leave a trail of blood after me.

    This could have some rather unexpected negative side-effects. For example, Lincoln was prone to depression - if he had been less melancholic, perhaps he wouldn't have spent so much time brooding over the negative consequences of slavery to the union. Similarly, this could spell the end to a lot of literature ...

      Depression is normal. However reoccurring bouts of depression lasting long periods of time which remove your ability to function in everyday life is not normal. That is the difference. Lincoln might have been depressed but he could still function with some normalcy. These people can't.

        Mr. Coward, you are correct. I had depression for a while. I learned quite a bit about what it is and how it works. First, you have so-called normal people. They may get sad and say they are depressed. These bouts may last days, for example, after a traumatic event such as the death of a spouse or parent. That is not real depression. Then there are people like me who were trapped in a bad situation for a long period of time and just couldn't deal with the pressure. That's just a worse case of the first scenario. Finally, there are the truly depressed people. They have a chemical or other imbalance in their brains that causes depression for no reason. Everything could be going well in life, and they just start crying, get into a funk, and can't get out of it. They may snap out of it and be okay for a while. Depression moves in cycles.

        I read an article in one of the IEEE magazines about two months ago on exactly this topic. Essentially, physicians implant an electrode in the patients brain that stimulates the area responsible for depression, so it helps avoid those slumps. It has a similar function to SSRIs, aka Prozac and other drugs that mess around with serotonin, but with few if any side effects. Similar to a pacemaker, a surgeon can implant an electrode and small battery into the patient's head that requires infrequent maintenance (every few years). If this works long-term, I think it will be a very good thing. Many otherwise productive members of society are unable to function at times because of depression. If we can remove that depression, we are stronger as a society, an economy, and most importantly, as a family. I know what depression can do to a family. It isn't pretty.

        Maybe Lincoln was depressed, maybe he was not. I am not an expert on that topic so I won't debate it. However, assuming he was, I think he would have been just as effective without the depression. Those same thoughts and tendancies in his brain would still be there, but he would have been clearer and more rational (not that he was or wasn't already, just more so). I know from experience that the times I was on the up part of my depression cycle I was clearer and more rational, but I still had the same thoughts. I just dealt with them better.

    • You've got to remember that this will probably be used (at least at first) as an alternative treatment of major depression for when traditional (chemical) treatments do not work. It will most likely be used when the illness is debilitating, where the sufferer cannot function. Creating works of art (or performing any task which requires intense concentration) in a depressed state implies that there's a modicum of function.

        I just hope no one in the trials commits suicide, a common occurrance of people who are just beginning to have their depression lifted.

        That's an interesting turn of events. You feel too depressed to do anything, then you start to come out of it. You still feel really down, but have the motivation to not want to feel like that anymore... yet can't imagine a lasting brighter future without coming back down again.

        So what's the obvious solution when you don't want to live that way, and don't believe you have an alternative? You make a choice to stop living. It seems very reasonable at the time (been close a few times myself).

          It's not about fitting in or creating a socially acceptable human being through chemistry. It's about relief from the prison of your mind.

          As someone that suffers from bouts of major depression and obsessive-compulsive disorder (OCD), if the treatment leaves me in a state of being "a bit off" but in a state where I can function in day-to-day society - that's okay.

          Without treatment, I'm prone to lie in bed all day barely able to speak (the depression) while my mind (figureatively) straps me in front of an IMAX screen and makes me visualize horrible things like blowing my brains out over and over again, throwing my son off a cliff, being gang-raped and other lovely sunny-day thoughts (the O in OCD). Obsessive thoughts are completely unwanted (they don't indicate some subconcious desire) thus feeding the depression which, in turn, makes it harder to block the obsessive thoughts. In my case, I wasn't hurting others (except my family who had to watch me go through those episodes) but I was hurting myself.

          While I don't think we should strive for a Stepford Wives kind of norm through medication, the medication is a godsend - not an Orwellian mind-control tactic. While you or someone else may think "so they're odd - leave them alone, it's who they are" it's *not* who they are. Who they are has been dominated and replaced by the condition/disease. I completely understand why someone that has not experienced mental illness might see things in the manner you describe. In fact, most people with mental illness won't tell thier friends or peers about thier condition because of the social stigma that mental illness carries.

          With treatment, sure there are days I'm "a bit off" but that's okay - no one's the wiser.

          I guess what I'm trying to say is that, while "oddballs and eccentrics" might not be hurting anyone, they may, in fact, be hurting intensely within - wishing they could rid themselves of the oddness and eccentricity and become the person they really are. The oddness is just a small part of what surfaces to the outside world. That's not to say that all oddballs and eccentrics are mentally ill either and that's truly just who they are.

          In regards to wondering whether these conditions are more prevalent than they were in the past - yes, based upon my personal research on the topic.

      Right! The glib tone of this post annoys me; I can't let it go by without comment.

      Before I start, both I and my wife suffer from chronic depression (and I'm bipolar). We both lead perfectly normal and happy lives - thanks to medication. So I know what I'm talking about.

      > 2. Shock treatment (as in for the loonies)

      Oh, thank you very much! I haven't had this, but my wife was so desparate that she did. I can't say whether it cured her (I suspect the medication has much more to do with it), but I *can* say that it is a brutal approach. I refused because I was afraid that it would damage my mind (which is a very good one - polymath). It tore her mind to bits! For months after the sessions she was confused, had massive memory loss (and those memories are gone for good) and suffered - possibly more than the depression itself. I think that one could compare it to resetting a computer by throwing a bucket of water over it. Quite possibly, its only effect is to press RESET on the brain and let it rebuild from there.

      > but spend more time on the down side

      Actually, the "up" side is even worse. You can do serious damage to yourself and those around you, mentally, spiritually, financially and even physically. At least when you're "down" you tend to stay put. Not that it's much fun.

      There is something in this, but it misses the point. People who want to mitigate the effects of the medication for any reason don't have *severe* depression. If you do, you will do ANYTHING to make it stop... and I mean *ANYTHING*. Why do you think sufferers kill themselves? In a way, I'm lucky because my disease started at an early age and built to a crescendo by the time I was 30. If I (or, I suspect, anyone) suffered the full effects in one go I would have looked for the very first way to kill myself - immediately.

      I do suffer some performance hit from the medication, but it's worth it. I once tried to get a boost for an important problem by stopping my medication. Never again!

      If you're a sufferer, don't worry about this. It really is fairly minimal and, as I said, very well worth it. Look at it this way; if you don't have to spend most of your mental energy fighting it, you're more productive anyway and much happier as well. In the course of my treatment, they concentrated on mitigating the symptoms, then hunting round for the correct drug and dosage for everyday life. It works very well.

      Finally, don't be ashamed. I know that there's a lot of stigma attached to depression and OCD but were you ashamed when you had a cold? Of course not! And it's the same thing - a disease. And it can be treated. If you have it, get help NOW! There is no need to suffer. It will take time and patience, but it can work.

      And, finally, finally: Remember you're not alone. Many others know how you feel (me, for example) and love and understanding can go a *long* way (soppy, but true). Where do you think my wife and I met? Yup - the loony bin (*I* am allowed to say it :) 15 years now (happy sigh).

For months after the sessions she was confused, had massive memory loss (and those memories are gone for good) and suffered - possibly more than the depression itself.

      IIANSDBS (I Am A Neuroscientist Studying Deep Brain Stimulation), and I attended one of the recent workshops that Medtronic had on this very subject where they brought together all of the physicians working on their pre-clinical trial of these devices. It was incredibly cool. Despite my having worked in the field for 6 years now, deep brain stimulation continues to astound me. The meeting covered exactly what you would think it would cover (and no, I'm not going to reveal any trade secrets or violate any NDAs): patient case studies, general results where such conclusions could be drawn, trends and statistics where available.

      First off, deep brain stimulation is not for the feint of heart. They permanently implant an electrode deep in the middle of your head. Actually, two of them. One on each side. This *is* brain surgery. Screwing up is a Big Deal, and, generally, brain surgery has a risk of complication measured at the 5-10 percent level. Then, in addition to these electrodes in your skull, there are wires which come out under your skin and route down to your chest to a permanently implanted stimulator. Actually, two of them. One on each side. This level of surgery is not something to be taken lightly. The target patient population is not people who feel a little down all the time; these are clinically depressed patients who spend the entire day sitting around doing nothing. Their lives are seriously impacted, just as seriously as someone who had a debillitating major physical ailment such as emphysima, heart disease, or a degenerative bone disease.

      Which brings me to the point of this posting, to comment on item 3 of the parent: many seriously believe "fixing" this, particularly the down or depressed side will decrease or neutralize the creative side of those who are exceptionally creative. The patients that this treatment is intended for are so depressed that they have no creative side. They are paralyzed by their depression. They do not function in society. They are barely able to nourish themselves, and, in some cases, require hospitalization or other form of daily care. The parent poster's assertion about this particular treatment is bunk. Brain surgery is not for people who feel down but are able to live halfway decent lives; Brain surgery is for people who are seriously broken. At this meeting, I saw videotapes of patients in the pre-clinical trials, and these are people who are before treatment so fogged by depression that they communicate in single word responses; they often miss appointments with their doctors because they cannot bring themselves to leave the house; they are deeply affected by their condition.

      Please draw your own conclusions about the effectiveness of the treatment by inference from Medtronic's pushing this forward to clinical testing. I, for one, am glad to see it advance.

    Anthony Burgess, author of the book "A Clockwork Orange" was the artist in residence while I was in the undergraduate program at the Iowa City Writer's Workshop [uiowa.edu] back in 1974. I think he based his book on the work of Jose M.R. Delgado, M.D. published under the book with the damn spooky title: "Physical Control of the Mind: Toward a Psychocivilized Society [amazon.com]".

    I managed to get a copy of the book finally, and discovered wonderful passages such as the following on page 115:

    ESB [electrical stimulation of the brain -- JAB] may evoke more elaborate responses. For example, in one of our patients, electrical stimulation of the rostral part of the internal capsule produced head turning and slow displacement of the body to either side with a well-oriented and apparently normal sequence, as if the patient were looking for something. This stimulation was repeated six times on two different days with comparable results. The interesting fact was that the patient considered the evoked activity spontaneous and always offered a reasonable explanation for it. When asked, "What are you doing?" the answers were, "I am looking for my slippers," "I heard a noise," "I am restless," and "I was looking under the bed." In this case it was difficult to ascertain whether the stimulation had evoked a movement which the patient tried to justify, or if an hallucination had been elicited which subsequently induced the patient to move and to explore the surroundings.

    This passage is eerily reminiscent of a passage from Richard Dawkins' "The Extended Phenotype [amazon.com]" chapter titled "Host Phenotypes of Parasite Genes":

    "Many fascinating examples of parasites manipulating the behavior of their hosts can be given. For nematomorph larvae, who need to break out of their insect hosts and get into water where they live as adults, '...a major difficulty in the parasite's life is the return to water. It is, therefore, of particular interest that the parasite appears to affect the behavior of its host, and "encourages" it to return to water. The mechanism by which this is achieved is obscure, but there are sufficient isolated reports to certify that the parasite does influence its host, and often suicidally for the host... One of the more dramatic reports describes an infected bee flying over a pool and, when about six feet over it, diving straight into the water. Immediately on impact the gordian worm burst out and swam into the water, the maimed bee being left to die' (Croll 1966)."

    I don't know how many slashdotters are familiar with people who've been treated for the more extreme side of clinical depression (I myself suffered from psychotic depression, a little more into the deep end, and will have to be rather vigilant on my mental state to keep from spiralling into it again), but if this works it will be a godsend.

    Most anti-depressants have really, really bad side affects; prozac is by far the best, but it seems to muffle several higher brain functions... not completely silenjce, but more than enough to be noticeable and very frustrating. Zoloft is the fucking devil and is extremely habit forming, not to mention that it destroys your liver and your immune system. Trying to quit Zoloft cold turkey is like trying to do the same with hard drugs, many people become very, very sick and suffer bowel and stomach problems for days. Zoloft can also cause those feelings in people for the entire duration of their medication; I was one of those people. I couldn't get up in the morning when taking Zoloft and not throw up at least once, and feel like I'd contracted anemia for the whole day. One of my dearest friends was medicated with Zoloft (at twice my dosage, which is ridiculous) for OCD and depression; needless to say, her liver has been annihilated. Even after a year of having stopped taking Zoloft, she maintains an acute weakness to food poisoning and alcohol, which was not present beforehand. Watching her try and quit Zoloft was like watching a train wreck. I've heard similar things with other forms of depression medication, but Prozac and Zoloft are the only ones I've been medicated with, and rather heavily.

    Depression is a real condition. Being "depressed" is not the same as suffering from depression. When you are sad and you know you will get over it that is being depressed and is part of the normal human condition. Depression on the other hand is a long dark tunnel, you can not see the light at the end of the tunnel and you hold out no hope that things will get better. It is not a feeling most people would consider normal although people who suffer from it accept it as a normal part of their lives (that is why so many fail to seek help).

    This chronic condition is very serious, it is the number one cause of suicide today. Chronic depression contributes to a whole slew of self-destructive behaviors and is a major contributing factor in alcoholisim, drug abuse, child neglect, and other very serious social ills.

    If life seems dull or you feel trapped inside of a bubble, if you can't find happiness when others around you do, or if you just never have energy, please see a professional (start with your doctor if you do not want to see a "shrink") to see if they can help you break out of the cycle. If you even think you may be depressed, it is time to see someone. If you think of killing yourself to escape it all, please drop everything and make the call right now.
