Ever-Happy Mouse Sheds Light on Depression

An anonymous reader writes "Scientists have bred a strain of mouse that's permanently cheerful, in hopes of better understanding and treating depression in people. By breeding mice lacking the TREK-1 gene, which is involved in serotonin transmission, researchers were able create a depression-resistant strain. They say it's the first time depression has been eliminated through genetic alteration of an organism."

    If you're incapable of depression, and you're always happy, how do you know if you really are happy?

      The same question goes for antidepressant drugs. I have spent long hours debating this with a doped up roomate as he gleefully skipped from psychoactive to psychoactive about the benefits and detriments of mommy's little helpers. I know that they got him through some difficult spots (without the psychotic episodes of his adolescence), but they also stifled his writing ability and effictively stopped his songwriting.

      He was successful in college and in work thanks to these drugs, but was he truly happy without poetry and music?

      To quote Trent Reznor: "I don't write a lot when I'm happy."

      I have a theory that says that the function of modern art is for the viewer to live vicariously through the artist's insanity. Van Gogh was famous for this. So was Leonard Cohen, Janis Joplin, Kurt Cobain, Alan Ginsberg, Salvador Dali, and Jackson Pollock, to name a few.

      Perhaps the question isn't "can he be happy without his poetry", but "can he make good poetry without his sadness".

      I'm not a big fan of permanently medicating the mind unless absolutely necessary... but when I had a episode of depression brought on by major illness, I wasn't thinking about poetry and music.

      I was thinking pretty much constantly about killing myself. Not little fantasies "God I should just shoot myself." No... we're talking cold, calm, and consistent thoughts. Very frightening in retrospect and even more frightening that it felt so normal at the time.

      Thank goodness I had family/friends to point me towards medical care. Lexapro changed that like a light switch, and the depression (and anti-depressants) are just a memory. But for some the depression is chronic and the treatment will probably need to be permanent.

      And yes, before that happened I never understood the potential severity and use for anti-depressants either. Anti-depressants aren't just about turning off maudlin thoughts of missing your dead turtle.

    One way is the 'forced swim test'. They put the mouse in a water tank from which it can't escape. The animal will normaly swim around trying to find a way out. If it is depressed it will tend to give up on swiming and spend long periods of time without moving. Another way is the 'tail suspension test'. It is prety much the same thing. The mouse is suspended on its tail. If it is depressed it won't give a shit about life and will just hang there. Give it some antidepresenats and it will move and try to escape a lot more actively.

    People on anti-depressants are not "non-challant" about everything so long as they take their pills. This statement shows a profound misunderstanding of what modern anti-depressents are like. As someone who been taking anti-depressents for most of my life (very long family history of it, suicides everywhere on my family tree), I would like to point out that these are not happy pills, mothers little helpers that makes you stop caring about the world. This is a common belief and one that is simply not true. I feel a full range of emotions like any other person, and the emotional side effects aside from the alteration of the depression is quite small. In fact, I feel MORE emotion that I would off my medication becuase depression tends to overpower other emotions. This was not as true with older varieties of anti-depressents, but the modern SSRI's http://en.wikipedia.org/wiki/SSRI have a minimal inhibitive effect on the range, duration, and power of my negative emotions aside from depression. Even more, I actually CAN get depressed even with the medications if the circumstances of my life dictate it. The ending of a relationship, loss of a loved one or whatever else might get a normal person depressed have the same effect on me. However, it is now short term and recoverable, that is, normal.

    Society should think of modern anti-depressents as you would a prosthetic for a person born without a leg. Although unnatural, it corrects a problem, bringing sufferers closer to "normal". Of course, becuase you cannot SEE my handicap, people assume that it is not there, and my condition is a character flaw or choice. This is not true, I have no control over it just as a schizophrenic has no choice in the perception of their hallucinations. Not everyone who is depressed needs these aids, but for sufferers of long term, chronic depression these medications are lifesavers, quite literally. Research and discoveries like those in the article bolster my confidence that future treatments will bring me even closer to normal.

    I am surpremely grateful that I live in the age of modern psychopharmacology, I am quite positive that I would not be here if it did not exist.

    Your sense of "depressed," i.e. not in a good mood , saddened, or discouraged by identifiable events, is confused with clinical depression, which is a horrible, debilitating, illness.

    In situational depression, e.g. death of a loved one, there is a clear exogenous cause of the depression. This is normal, and is usually worked out "solo" or through counseling, sans medication, or in some intractable cases with short-term use of medication. However, chronic clinical depression, dysthymic disorder, and their ilk are pathological. Depression is a disease. Your method works for most healthy people, but a clinically depressed patient is in open-loop mode: logic, reasoning and "working it out," as you say, don't work. It is wonderful that you are healthy and have worked out your own problems on your own sans pills, but the lives of countless people--whose brains are wired differently than you--have been saved or extended by antidepressants.

    Insightful? Believe it or not, there are people who cannot function or would be dead were it not for antidepressants and counseling. Talk to people who have had the actual disease. Empathy will come to you as you grow up and get outside your own myopic view of the universe.
