ikarous | 14 years ago | on: The Hushed Dangers of Startup Depression
No, I do not think that. In fact, I stated quite clearly that depression causes measurable changes in brain morphology and function. My entire argument was to support the assertion that the phrase "chemical imbalance" is merely an insufficient label for a complex psychological and biological phenomenon.

SSRIs, or serotonin reuptake inhibitors, are the most commonly prescribed antidepressants in the United States due to their relative safety and efficacy. It is widely thought that these drugs achieve effectiveness through their ability to increase serotonin levels in the brain. Now, here comes the mystery: while serotonin levels rise almost immediately following introduction of the drug, the antidepressant effects do not become apparent until several weeks of treatment have passed. Why is that? No one knows for sure, but a few interesting theories have emerged.
The most interesting theory, in my opinion, involves hippocampal neurogenesis and BDNF levels. A few recent studies have shown that one thing that the SSRIs share in common is that they all promote neurogenesis in the hippocampus. A further study showed that the antidepressant effects of SSRIs on behavior in rats exposed to artificially induced stressors could be completely nullified by slightly irradiating the hippocampus, thus negating the growth of new neurons promoted by the SSRIs. The antidepressant effect was gone even though serotonin levels remained elevated.
This conclusion provided compelling but not conclusive evidence that neurogenesis is involved in antidepressant effectiveness. Yet even here, the picture was not altogether clear: while patients diagnosed with clinical depression generally show less hippocampal neurogenesis than controls, it is not at all clear whether this deficit is a cause or effect of clinical depression. Is it possible that depression, once established, can cause physical changes in brain structure? If so, that might explain why cognitive behavioral therapy in conjunction with antidepressant medication is a more effective depression treatment than either of the two alone.
Interestingly enough, strenuous aerobic exercise is known both to be an effective treatment for mild to moderate forms of depression as well as a promoter of hippocampal neurogenesis. An increasing number of psychiatrists are in fact prescribing exercise regimens as treatment for some forms of depression because it seems to work.
The bottom line is: there's a lot we don't know about depression, and while we have effective treatments, the reality is that the causes of depression simply cannot be adequately summed up as a "chemical imbalance." Drugs are appropriate for some patients and inappropriate for others. I encourage anyone interested in the subject to do some reading, as the brain is (at least, to a layman like me) the most fascinating information processing system ever.

You obviously mean well, but this statement bespeaks ignorance about suicide prevention. Most but not all suicides are preceded by warning signs, and talking about it openly automatically places the speaker in the high risk category.
The intent to kill one's self begins with ideation and grows from there. At first, idle thoughts about killing yourself begin to drift through your mind at random. Driving down the freeway, out of fucking nowhere, you imagine yourself veering into oncoming traffic. Or maybe you're in the kitchen taking an Advil and the thought comes to your mind, unbidden, to just down the whole god damn bottle and chase it down with vodka.
These images are like demons, and they are not easy to exorcise. As the imagery and impulses grow more intense and vivid, some victims will say something to offer a clue to those around them or to ask for help. The problem is that this warning often doesn't seem serious because the victim is so torn between two conflicting desires: 1) the desire to end suffering, and 2) the desire to live.
You see, the crux is this: just because someone doesn't want to die doesn't mean that they won't kill themselves. If they're talking about it, then you should treat it as though they're asking for help. I missed the same warning sign because I thought just as you did, that those serious about suicide would be dead rather than talking about it. I was wrong. The only thing that saved her was luck. Luck and a responsive ER.
Take it seriously.
ikarous | 14 years ago | on: Show HN: weekend project, an attempt at a simple bed time calculator
Case in point: I've known a number of individuals with highly variable sleep schedules imposed by their work who performed this calculation manually. I imagine that they would find an application or a cycle-aware alarm clock on their phones to be quite handy.
Aside from that, calling someone's work the "dumbest thing you've ever seen" is both unnecessary and probably untrue. Please don't be uncivil.
ikarous | 14 years ago | on: The economics of good looks
Case in point: a few years ago, I noticed that my hair wasn't quite as thick and lush as it once was. I panicked, stupidly. Without performing adequate research, I began taking a medication that blocks the hormone DHT. Only later did I learn that this medication can subtly alter cognition by affecting the production of various neuro-steroids. Obviously, the value of my mind vastly outweighs that of my appearance, so I stopped taking the medication knowing that one day, I'd probably lose my hair because of it.
Despite the obviousness of the choice, it was ridiculously difficult to implement. The social imperative to be beautiful is powerful. Yet:
You aren't your hair. Or your face. Or your breasts.
It may very well be that attractive people have it easier than less attractive people. But that's a problem with human nature, not with those not blessed by beauty. Make reasonable steps to improve your appearance, then forget about it. Self confidence, humor, and a compassionate nature will always win the day with people who matter.
Ask yourself: is Steve Jobs as classically attractive as Brad Pitt? Who is more accomplished? Isaac Asimov? Donald Knuth?

Whether the cause is simply my background or is perhaps strengthened by some neurological factor, I am completely unable to filter out superfluous external stimuli.If someone is talking on the phone in the same room with me, I can't not listen to their conversation no matter how much I wish otherwise.
The people with whom I work tend to have difficulty understanding this aspect of my nature. I'm afraid I come off as rude and aloof when I put on my headphones and request to be IMed rather than tapped on the shoulder. Generally, these requests are ignored. One of our sales people actually came over and pulled my headphones off my head. My startled reaction did not go over well with her.
I'm not asocial. I like people. I just need silence to think.

Post hoc, ergo proper hoc? I don't necessarily disagree with you, but don't you think that there might be more contributing factors? In particular, the decline of the American auto industry comes to mind in regards to Detroit.

I brought in my own chair (a used Steelcase Leap) and my own keyboard. That helped a lot. Even so, I still have to get up frequently throughout the day so that I don't get back or shoulder pain. When I do, I get suspicious looks from folks who think I'm not working hard enough.
The irony is that I work at home on my own time because I'm more productive there.

A poster upthread linked a video about getting work. The speaker advocates doing free or nearly free work in whatever interests you most, the theory being that these activities will eventually pay off. I think it's a fabulous if rather unorthodox idea. Since we're financially stable with my income, I've told him to give it a shot.

The unspoken assumption is that these more interesting jobs are plentiful enough to support the displaced workers assuming that they're willing to train and transition into a new kind of job. Is this the case today? Are the "higher" jobs plentiful enough? The question is not rhetorical; I'm asking because I can't say. I work in software development and my perspective is limited.

What I do know is that this whole situation is terribly discouraging for young people fresh out of school. My partner, for instance, recently graduated with a degree in civil engineering from a very challenging private school. He's been unable to find work as a starting engineer after a six month search, and I'm frankly out of ideas on how to keep him optimistic. Add to all this that his dad, a senior electrical engineer, just got laid off, and any encouraging words I say start to sound very hollow indeed.
I fear that this high unemployment rate, temporary or not, is going to create a generation of career setbacks and failures to launch. A lot of people out there have it much worse, I know, but I still don't know what to say when this hard working young man can't even get responses back for internships and unpaid work.

They most assuredly do not. I am a gay engineer. I've never known anyone so blatantly deceptive, but if any of my acquaintances even thought about doing something like that, I would give them a dressing down that would make a drill sergeant cry.
Gay people are like any population sample. 95% of them are normal, decent human beings; 5% are wackos.
