New MRI Studies Show SSRIs Bring Rapid Changes to Brain Function 138

A story at the Los Angeles Times reports that researchers at the Max Planck Institute have found that Selective Serotonin Reuptake Inhibitors, various of which are widely used in anti-depressant medications, cause changes in healthy subjects' brain architecture just hours after ingestion. As the article mentions, one reason that this rapid change is surprising is that patients taking SSRIs to treat depression typically take considerably longer (weeks) to perceive a change in mood. A slice from the story: When more serotonin was available, this resting state functional connectivity decreased on a broad scale, the study found. This finding was not particularly surprising -- other studies have shown a similar effect in brain regions strongly associated with mood regulation. But there was a two-fold shock: Some areas of the brain appeared to buck the trend and become more interdependent. And all the changes were evident only three hours after the single dosage. ... The rapid connectivity shifts noted by the study might therefore be precursors to longer-term changes, perhaps starting with remodeling of synapses, the microscopic gaps where chemical neurotransmitters such as serotonin flood across to an adjacent brain cell, the study suggests. But this type of brain scanning can’t pick up changes at such a scale, so the hypothesis will have to be tested other ways[.] ... Study subjects did not have diagnoses of depression, so researchers will need to generate similar maps among those diagnosed with depression, and re-map them during and after depressive episodes, as well as after treatment, Sacher said. Comparisons might then show whether a certain initial architecture predicts treatment success.

    I found that the SSRI that I took for a total of about 18 months (for diagnosed depression) was mostly helpful in allowing me some clarity to so that I could identify, build and grow the coping mechanisms that helped me maintain clarity without the SSRI. I've been free of needing the drug now for about 8 years and have found ways to cope on my own (changing my mind among others as Tim Leary used to say)...

      ...was mostly helpful in allowing me some clarity...

      Depression isn't just about feeling sad. It's a whole range of negative emotions including guilt, hopelessness, lack of motivation, lack of confidence, etc. The opposite of depression is being manic - where a person feels happy, supremely confident and motivated, that everything is possible, etc.

      Now, you seem to be hinting that the SSRI made you smarter (i.e. gave you clarity). But that's unlikely for a variety of reasons. Instead, it most likely made you feel smarter, more confident, etc. And maybe that's what you meant - that you had a unrealistically pessimistic view of the world and the SSRI caused you to have a less pessimistic view of the world.

      For many people, being able to biochemically feel more motivated and less concerned about the consequences of their actions is exactly what they need. Maybe someone lost their job in a particularly unpleasant way and they're having trouble getting back on the horse, so to speak, and looking for a new job - and then the fact that months are going by and they're still unemployed is making them even even less motivated, etc.

      But consider someone who is so desperately unhappy that the thing they want more than anything is to not exist - but they're held back by lack of motivation and concern for the consequences on their family. If you biochemically alter such a person's brain to feel more motivated and less concerned about the consequences of their actions then you made an already dangerous situation much more dangerous. Now, SSRIs are often prescribed together with valium derivatives which could potentially take the edge off and make a person less unhappy - dulling the desire to cease to exist - and perhaps also dulling the motivation a bit. And then there's also depression caused by an external situation. If someone is depressed because they're in an abusive relationship then obviously SSRIs are the wrong solution (i.e. the right solution is to get out of the relationship).

      Which is all consistent with this latest study. Depression isn't some simple biochemical imbalance that's cured as soon as the SSRI diffuses across the blood-brain barrier (i.e. a time scale of hours). And, to the extent that SSRIs do have a biochemical effect on mood (i.e. subtracting the massive placebo effect) it's important to be very careful that this biochemical effect is actually beneficial to the patient because if you get that wrong you end up with a dead patient.

        that you had a unrealistically pessimistic view of the world and the SSRI caused you to have a less pessimistic view of the world

        You seem to assume that "depressed" means "unhappy" or "pessimistic". I've had depression for almost a decade while being happy and successful and an overall optimistic person who looked forward to his work day and time with friends and family.

        I had a lack of energy and motivation, but I enjoyed being with people and doing stuff, but I relied on others to motivate me and I always wanted to sleep and do nothing. I also had anxiety, not a "fear" of anything, just my mind would race when I felt stress. I tried an SSRI, but I almost immediately got an adrenaline rush off of it with only a half dose that left me with almost no sense of pain, exaggerated movements, huge amounts of energy, and a 140 pulse that wouldn't let up for almost an hour. I eventually had to immediately see a doctor who gave me something else to counteract it. I had a few bruises and sore joints and tendons after that.

        Eventually my doctor got me on Lorazepam for when I felt strong anxiety. After several months of using Lorazepam whenever I had my attacks, I noticed I got anxiety less and less. I have not had an anxiety attack in 6 months now and I now feel more energetic and I want to go out and do things, starting to exercise again, even taking up learning a new language. I'm also finding that I can think clearer and remember stuff distinctly easier. I'm just glad I haven't had to use Lorazepam in a long while.

        I find it interesting that my ability to concentrate and remember is better than ever. I grew up with A.D.D. from kindergarten on, which continued to cause me issues up until very recently. A lot of my A.D.D. issues have subsided after my anxiety went away. No idea.I only used Lorazepam for a little bit, but it seems to have been a miracle worker in my case.

      That's how it is supposed to work. It's a crutch to allow something like cognitive behavioral therapy to take hold.

      Ideally, you would be seeing a psychologist to assist with identifying coping strategies, or problems with the way you filter input. Instead of triggering negative responses, everything you experience in a day should be more or less balanced. Not perfectly 50/50, but certainly not always negative.

      Getting in a negative rut ("depression") makes it easier for a neutral stimulus to trigger a negative emotion, or something that should be positive to be misinterpreted.

      An anti-depressant can't change the way you react to what you hear, read, or see. But it can give you enough of a lift that you have room to work on yourself.

      As long as I'm typing - someone will probably mention cocaine. Similar caveat with cocaine - it doesn't help you change your mind. It actually gives you a positive feeling, which current anti-depressants don't really do. The need to change your mind goes away, temporarily, and users look to another hit to solve the problem. It's a great demonstration of how feeling good might feel, but serves no other useful purpose.

    The study is interesting however, it is notable that no one studied had a diagnosis of depression. It so happens that I am autistic and have Autistic Spectrum Disorder and suffer from Major Depressive Disorder. Being autistic, I have certain stimuli that I am very sensitive to and others not so much. I noticed almost an immediate difference when I started to take Prozac. I've always been sensitive to medicines and I noticed some initial feelings along the lines of things seemed clearer somehow.

      That's a very good point. We know what happens to the chemicals in the brain, and we know that after some time people feel a bit better, and we know that is rarely permanent.

      There was a great article in Newsweek or Time (I can't find it now...) that pointed out this delay. The chemicals happen immediately, but it is weeks before any effects are seen.

      One idea was that the brain is damaged, and has to be repaired. It didn't make sense, but there are studies that report decreased brain tissue, or ridges, or various measures of physical properties.

      I don't remember seeing any follow-up that showed reversal of brain tissue decline, which might prove this idea.

      Anyway, I suspect that your sensitivity to stimuli would have made you aware of the chemical differences faster than most people. And it could be possible that the ASD makes you more susceptible to depression - *without* the physical atrophy that may or may not underpin most non-ASD depression. You did not have to endure the brain rebuilding that most people might.

      All of this post basically points out that we don't know how the brain works, and if you have multiple differences from the norm maybe we super don't know how it works. If chemicals made you feel better, good. I don't think anyone can really explain why.

        Although people are generally told that SSRIs take several weeks to work, many patients report that some effects are noticeable in the first few days. These are usually improvement in anxiety symptoms (depression and anxiety commonly coexist).

        So this doesn't surprise me all that much. What will be interesting is to follow 'normal' and depressed people over time with and without treatment. However, given how annoying MRIs can be (confining and noisy and slow) I wonder if there will some sort of bias created with some people opting out of frequent testing.

But SSRIs are totally the opposite of addictive drugs, they don't give anything resembling immediate pleasure (in fact they can be somewhat to very uncomfortable for a while), and only benefit after weeks or months of use. They're basically giving you constant anxiety and nervousness - which is bad, except that it forces your brain to adapt by making the serotonin receptors less sensitive (which takes about t

          My experiences with Zoloft and Paxil suggest that side-effects, most especially related to my physical appetite and sleep schedule, occur within 12 hours of starting medication or a change in dosage. I can't say I ever experienced any positive impact from either medication in the couple of years I spent at various dosages, but do know that all three of the physicians I was seeing swore up and down that SSRIs don't work like that.

          I likewise found that a mental fog settled over me within a few days of starting each SSRI that I try. I felt more like I was controlling a video game character than experiencing any part of my own life, to the point that I would at times find myself sitting in the passenger seat of my own car, wondering why it wasn't moving.

          I eventually decided that the pharmacological aspect to my treatment for depression was doing far more harm than good. I have to say that I have a strong distrust for purported utility of SSRIs, and a vastly lower opinion of mental health providers in general as a result of my experiences.

      SSRIs can increase suicidal tendencies when initially starting treatment. This is because SSRIs improve motivation before mood, and it is the reason you start a dose under close observation. Additionally, SSRIs can have a whiplash effect when stopped cold turkey, potentially increasing anxiety and depression. SSRIs MUST be tapered in order to safely withdraw from them. This are all well-known, studied effects of this class of drugs. Though these effects don't occur in all patients, it's frequent enough to warrant caution.

See TFA as an example. I'm doubly skeptical on using SSRIs and other drugs on childrens, adolescents, and even young adults, as there are even more uncertainties about these drugs on still-developing brains!

      Having said that, SSRIs are common medications today. The kind of people who are suicidal or have such a mood-disorder that going on a shooting rampage seems like a good idea are exactly the people for whom you would expect SSRIs to be prescribed! In other words, are SSRIs causing these issues (and earning your blame), or were the problems there to begin with?

    • When you're really depressed, you're unlikely to kill yourself. That takes initiative. Something that increases initiative without seriously reducing the emotional pain will make suicide more likely. Moreover, you're unlikely to get monotonically less depressed. At some point, you're going to feel the depression coming back, and you will have not only motivation and initiative but a very strong reason to do anything necessary to not get depressed again.

  • Is mood a state-to-be achieved (intentional in some way), or is it some symptom of the total complex and state of brain chemistry at a certain moment.
    'Mood regulation' to me smacks too much of some homunculus.

      Both. How you feel is defined by the chemicals in your head, but you can learn to control them or learn specific thoughts and techniques that change the chemical make-up in predictable ways. Thus giving you the ability to reach a specific mood by intention.

    Study subjects did not have diagnoses of depression

    If they do not have the problem, how could we hope to see something about the problem improvement?

      Because our understanding of how SSRIs operate on the most basic level is still very poor, and the research in question has found some clues about how to proceed. It makes sense to eliminate the variable of serious mood disorders, since the mechanisms behind them are poorly understand and differential diagnoses are a huge problem. Before fixing your car that runs rough you have to have some idea of how it works and what your tools do, and that's what this study was about. Hopefully some day soon we'll have a more thorough understanding of depression and similar ailments, as well as why some drugs help some people, but we are a long way off.
    • It's obviously the beginning of a research project. Take a drug - see what it does to 'normal' people with the testing platform you are using (in this case functional MRI), then try it on different clinical diagnoses. Remember, most medical diagnoses and especially psychiatric ones are not binary events - they lie on a continuum. We really don't know how to diagnose most patients with complex psychiatric problems. We typically give them several overlapping diagnoses that really don't explain the patient

      • The main problem is that psychoactive drugs have VASTLY different effects depending on your baseline of operation. Especially with you're dealing with a drug like an SSRI, which by itself doesn't put something into your body but rather keeps your body from eliminating something.

        That first and foremost requires something to exist, and the lack thereof IS exactly the problem.

        Is it me or is it considerable bullshit to examine the effect in a healthy specimen?

    The premise of the story is flawed. While SSRIs take a week or two to show positive results, the initial effects of the drugs are almost immediate. I've taken anti-depressants and I can say that there is a very quick emotional reactions to them. Not a positive reaction, but there is one there. Friends who have taken the drugs and I agree, there first few days brings a roller coaster of emotions and a sick-to-the-stomach feeling. That eases off after a few days followed by a dull fuzzy feeling, followed by t

    • My reaction was different. I didn't have any major effects when I started taking Paxil, except that a few days later I felt there was now a floor that would support me if my depression tried to increase. I have no way to tell whether this was a placebo effect or not.

      SSRIs are well known to cause sexual dysfunction in males (some SSRIs and some males more than others), but this is the first I've heard about escitalopram increasing sexual stamina. As such, I wouldn't rule out a placebo effect, especially since so many factors can affect libido.

        Posting as AC -- the effect is to interfere with the ability to "finish." For those with premature "issues," this can be a benefit. For those of us with "normal" "stamina," it may cause an inability to "finish," essential providing infinite, though very frustrating stamina.

          Yup, the parent is correct, SSRI side-effect can be frustrating on one's own but in the right company being a (apologies) 'machine' does have its advantages.

        When I was on Paxil, I went ~15 months without once having a conscious hard-on.

        • That's why I switched to Zoloft: after a month or so, my mood had considerably improved, but I realized I hadn't had a conscious thought about sex in that time.

    A long time ago, I took an SSRI called Luvox in order to treat OCD. Within a month, the drug had turned pain signals into pleasure. Headaches, burning myself via a hot water faucet--I would literally feel pleasure from these normally painful experiences. I stopped right away, and those effects lingered for a decade. Prior to that, I had taken Prozac and Zoloft without significant effects that I remember. But after seeing an SSRI make my particular brain sadomasochistic, I never popped another SSRI pill and I never will again. They really do change the brain, and I'm convinced that the outliers (read: really smart people with non-normal brain chemistry perhaps--at that time, I was pretty damn smart :)) have brain chemistries that react in vastly different ways than the baseline. I know this isn't exactly on topic, but it was shocking how much my brain changed from what should have been just the early trial period of the drug and for how long that lasted, and frankly how much it pushed me into brand-new areas of being f'ing crazy. I would heartily recommend against using these things, especially to the types of people that are going to read 0-level comments on slashdot. :) I'm also convinced that even if it seems kinda normal, it could very well not be and be royally messing up other parts of your consciousness that just aren't as apparent as suddenly pain=pleasure. And I highly suspect this kind of thing is happening when kids who see psychiatrists and are on drugs, smart loners, go f'ing nuts and kill people. Random rewiring of the brain because they have unique chemistries. That's just my theory though, just knowing how "crazy" I got. I figure it more or less follows from giving these things to so many people and knowing how drastically wrong they can go. And sadomasochism may not be the right term as it didn't involve sexual feelings or anybody else. It's just like my wires got crossed and stayed that way, tapering off, for a decade.

If accepted, this will be the largest fine imposed on a drug company, surpassing the $23 billion paid by Pfizer for inappropriate marketing in 2009. The amount adds to GSK's $750 million settlement in 2010 over manufacturing quality. What is particularly egregious about GSK's fraud is the calculated deceit and potential human co

  • Yes, whenever I started taking antidepressants I could feel SOMETHING happening within a few hours, so that's not a surprise. But as others have said, the depression doesn't lift for a while - weeks to months. In fact, the nervousness and anxiety gets worse than ever for the first week. (No surprise that suicide is common soon after starting them.)

If fMRI was used, then it can only be a functional difference, there is no way to observe a structural change with fMRI unless it is something gross (like a 5x5x5mm cube of brain tissue suddenly went missing). If T2-weighting was used, then one is still limited to fairly gross changes (lets say a cube that is 1 mm^3 in volume). Finally, we arrive at the various diffusion MRI techniques,
