It's a long read, but my short version would be this: "Depression is a mode where the brain underweighs evidence from new experiences in favor of pre-existing negative prior assumptions."A lot of people with an unknown medical issue are dismissed as depressed.
In either case the treatment is the same. Doctors and psychiatrists are powerless to do anything to actually put their patients in safe and wholesome environments.
Regardless, if you're depression is because your life sucks so much that it makes sense to be that way, and has so for years, something is still very wrong.
Isn't this what brains do typically, outside of depression?
I omitted the word "negative" from the quote as that part I don't think is universal. It still seems a somewhat limited modifier in modelling depression.
The linked article's paragraph on "lumping together depression and trauma" also seems to accidentally expand on this conflation. I understand the causes of depression are likely numerous, so natural tendencies of those not prone to depression can't be ruled out as contributory factors, but I'm not sure I see an argument there for their being significant.
For a definition of "depression", it is. If somebody always believes that everything is great, regardless of the evidence, that might be a problem, but that problem would not be called "depression".
> Isn't this what brains do typically, outside of depression?
No; the theory is that typical brains do a certain amount of consideration of new evidence, and depressed brains do less than that.
The same article goes on to point out that there must be more to it, since as described this model would still result in depression naturally clearing up.
That dealing with trauma is not forgetting old behaviours but learning new ones?
It was a charming part of their lives (e.g. going to see all 7 of grandma's prized typewriters in their basement), but trying to sell those 7 typewriters on ebay only to just give up and have some estate sale person come through and basically pay a small portion of the value of things just to get it off your hands is the only option.

“Put another way, you are more upset about losing $50 than you are happy about gaining $50,” the paper states.

Not all doctors are familiar with its use in this way. When I had to switch doctors after mine retired, I had to educate them in its use so that they would continue prescribing it.
It is also not an automatic approval by insurance companies. However, if denied by your insurance, you can get it at a fairly reasonable price using GoodRX.
If you're still struggling after what you're already one, and have gone through a few other options (and maybe even if you haven't) then I would highly recommend talking to your doctor about this.
Something to keep in mind though is that this will, mostly in the first week, impact your sleeping patterns. Taking it first thing in the morning would be the best time, and perhaps ask your doctor about using an over-the-counter sleep aid such as diphenhydramine during initial usage.
Interestingly almost everything that induces sleep harms the actual sleep quality. However I remember reading that GHB appears to improve sleep architecture, although I’ve never tried it personally
2. Using GHB/Alcohol/Marijuana to help you feel more rested really depends on if the person has a medical condition or not. All of these drugs will suppress REM sleep (so will your typical SSRI), which for the average person may not be a good thing. However, those with narcolepsy have a much higher rate of REM sleep, preventing their body from going into deep sleep and thus (says the hypothesis) they don't get the awakeness/alerting benefits from sleep.
Interestingly, those with depression and PTSD also have increased rates of REM sleep, so there is an interesting question of causality there.
Citation needed about the SSRI part, because one typical side effect of SSRIs is unusually vivid dreams.
I agree that the two data points are paradoxical, and I'm not sure what to make of it. Personally I have a much larger than average amount of REM sleep (confirmed by professionals when I was tested for narcolepsy/daytime sleepiness), but I do not have vivid dreams and seldom recall dreaming at all, despite talking and moving in my sleep. Nevertheless it's quite interesting.
One hypothesis could be that less time in REM sleep leads to more intense bursts of REM, thus more vivid dreams? Or perhaps I am lacking knowledge and there is more to dreams than REM sleep.
Melatonin isn't too bad for actual sleep I think, but almost all supplements give you way too much - something like 1/3mg is enough. It does give me really bad dry eyes in the morning for some reason.
Probably not a good idea to experiment personally with GHB because it's Class I in the US and associated with date-rape, but it's worth considering in studies and research.
It does seem to be the case that disordered sleep is the keystone of depression; I can also confirm missing one dose of mirtazapine at night feels exactly like an alcohol-induced hangover in the morning. I suspect depression accumulates during sleep.
Interestingly, mirtazapine is a powerful H1 antihistamine that induces sleep at lower doses that are swamped by noradrenergic effects at higher doses. I would guess patients on mirtazapine have fewer incidents of seasonal allergies.
Just asking this out of curiosity, because I'm also someone who consistently experiences antidepressive effects from modafinil. Though for me it's typically more of a feeling that lasts for about 1 - 4 hours after use rather than a steady, stable mood lifting effect.
e.g. an autistic teenager who got beaten up for being socially clueless or abrasive. Anxiety might be the thing that saved them from being seriously harmed.
Your ancestors and my ancestors stuck around long enough to reproduce and raise their kids without offing themselves from depression, has something changed to make the environment less conducive to being a living human?
Note the above is not to suggest that there’s not a number of factors of a modern environment that we’re not properly/perfectly adapted for. But the handwavy “people weren’t depressed and anxious in the old days” is an illusion.
Turned out practically everything bothers me.

It's not as if people go around saying, 'good morning! I had my usual poop today, a good #3 on the Bristol stool scale, placing me within 1SD of the human norm! And yourself?' 'Likewise, likewise; good checking in with you and discussing our morning defecation, as is very normal for us human beings, ha ha.'
That we can look at the lives of millions of people in America in 2021 and call their abject misery 'maladaptive' or 'overlearned' is ghastly. I know I'm supposed to offer more in an HN comment, and I'm not trying to call you names. But if I told that to someone in psychotherapy I'd deserve more than just losing my license.
I don't doubt that looking inside people's biology for clues about what's going on when they suffer these kinds of anguish is interesting or potentially helpful, but I can say two things quite confidently on the matter:
1) After 60 years of dominance, the biological-psychiatric project's track record is dismal and has failed to move any population-level needle on the levels of suffering it tries to study and ameliorate
2) Focusing on biology at the expense of questions about "context" or "environment" or "maybe this depressive is reacting exactly appropriately to their horrible existence" is a staggering waste of brainpower and money and time, and it leaves me at a loss for words. Outside of the social strata represented on HN (and probably within it to some degree) the world is "threatening, unrewarding, and pointless" for vast numbers of human beings, and I'd challenge anyone to sit in front of such a person and tell them to their face that it isn't. If there exist "regular experiences which should falsify those beliefs and lead to learning (but doesn't)", I got news for you: those experiences aren't prompting "learning" because they're not enough. This is like telling hungry people to feel more full after feeding them a saltine cracker.
You can't "cure" depression by pumping people full of prescribed psychotropics - the major mental health effort of the past half century - any more than you can do so by pumping them full of vodka. Address poverty, address violence, address a litany of social ills - and I mean really address them - and you'll see what happens to depression.
Excuse me, but this touched a nerve.
> I am deliberately rejecting our present easy distinction between sickness and health, at least as far as surface symptoms are concerned. Does sickness mean having symptoms? I maintain now that sickness might consist of not having symptoms when you should. Does health mean being symptom-free? I deny it. Which of the Nazis at Auschwitz or Dachau were healthy? Those with a stricken conscience or those with a nice, clear, happy conscience? Was it possible for a profoundly human person not to feel conflict, suffering, depression, rage, etc.? In a word if you tell me you have a personality problem, I am not certain until I know you better whether to say "Good" or "I'm sorry". It depends on the reasons. And these, it seems, may be bad reasons, or they may be good reasons.
Life is miserable here. And people don't run to hang themselves. They are trying to find happy moments and relish in those moments.
It's absolutely normal for a man to live in misery. Our humanity lived in misery for thousands of years and billions of people are living in misery right now. Our brain should be adapted to it by now.
I know it's a tired trope to throw around at this point, but it just shows there are countless variables that factor into one's mood and disposition and sense of motivation even before you dig down to the neurological and biological levels. Leave a healthy, well-fed, "rich" rat or chimpanzee alone in a low-stimuli, not very large room for long enough and they'll often become depressed. Embed someone born in a wealthy country into an indigenous group and they often report feeling more alive and not depressed. Do the reverse and you often get the reverse.
And of course many people feel all these things not due to any sort of stagnation they have any personal control over but due to neurological systems which may be difficult to alter. Or both.
I think the original reply post may have partly misinterpreted what the commenter was trying to say. The hypothesis being discussed is something like that even if you reintroduce the rat back to its previous happy environment, their potential predictive processing dysfunction may cause them to not be able to do anything but treat all stimuli the same: not worth caring about or trying to derive enjoyment from.
What country is this? Your domain seems to indicate Kazakhstan, but they have one of the highest suicide rates in the world, so I suppose that's not it?
Meds were a godsend. They allowed me to escape from depression long enough to deal with depression. Could I have done so even while still in a shitty environment? Probably, because the key ingredients for me were: meds, learning to identify good things, and not burying my feelings.
That’s not to say we shouldn’t be solving all these problems, but in the meantime let’s not tear down things that work for people because they don’t directly address a more intractable root cause.
I’ve used ADs as a “band-aid”: something for three months or so at a time when necessary, to stop me a) killing myself [though thankfully it’s been a long long time since I had those intrusive thoughts] and b) giving me just enough “normality” to go and make whatever changes I can that pushed me in the direction of an episode or made an extant one worse, and lastly c) give me enough motivation that I can work properly with my psychologist/psychotherapist.
I’ve had very good “reasons” for my crippling depression, but usually I can’t see the forest for the trees to work out what it is while deep inside the episode.
Luckily for me, citalopram works with basically no side effects when taken for a couple of months. I’m glad that’s the case, but I’ve seen so many of my friends get no relief from ADs at all, along with so many (sometimes life altering!) side effects, that it makes me sad at times.
Lastly, buprenorphine is remarkable for me in terms of its anti depressive effect. Once monthly Buvidal injection not only solves my past issues with drug abuse, but neatly solves my depression. Fascinating stuff.
people with depression have been shown to have a more accurate perception of reality. it's the rose-colored glasses view which is adaptive.
>they're also used to treat a spectrum of anxiety disorders like OCD and panic disorder
A massive amount of people treated for depression have panic disorder because of these drugs, so they can treat or induce the same thing in different people.
1) We've had a good idea of the pharmacokinetics for a little while. All this research does is enhance that knowledge and take it one level deeper. Essentially, we've just gone one turtle lower in the pile of turtles standing on backs.
2) No theory of how antidepressants work will complete until we also understand why they so often do not work for many people.
No small task, of course, and the paper's pretty interesting, but it's not clear this has anything to do with what we call depression.
There are many abstraction levels in the process and mostly we have to make large jumps over them.

Can you think of a small piece of machine code that you could inject into arbitrary computers that would produce useful effects in some significant proportion of the computer population? (Don't think so...)
Computers and biological systems are so wildly different. Although perhaps you'd find better analogies comparing brains to machine learning systems. Eg. "Trying to find out how ADs work is like applying some simple numerical transformation on some particular part of a deep neural network and trying to find out what changes are produced".
Oddly enough.. I think ML researchers often do find little "tricks" that improve the performance of neural nets without being able to fully grasp how or why. It's somewhat similar to how we use and understand ADs.
The difference between biomedical and electronic systems vanishes when you approach them from the same abstraction levels, where the complexity of the brain forces us to stand: either extremely high (clinical/GUI) or extremely low (drugs/'therapeutic' machine code).
My understanding of brain is on par with that most of HW audience has about computers and vice-versa. So, as you correctly thought, the intent was to brigde this gap. Another analogy I like is, treating brain diseases with drugs is like repairing a car by spraying chemicals.

>About 27 years ago, a little company that I worked for was going through another transmutation in order to survive. We became a high-throughput screening/combinatorial chemistry company. The CEO told a story about how, by the time anyone figured out that we didn’t know what we were doing, we might actually figure out what we were doing. I volunteered to be the technical lead on the combi-chem side. Anyhow, we managed to get bought by Lilly in 1994 and shortly afterwards, we got a visit from Bryan Malloy (https://en.wikipedia.org/wiki/Bryan_Molloy), the inventor of Prozac, who came down to see what his company had purchased. I met with Bryan and we had a lovely chat. But, he let me know that he thought that what we were doing was no better than “pissing in the wind”.
>I guess this means that he was doing much the same.
As the Church fell out of favor during the Enlightenment the very first Psychiatrists literally asserted that all the people who were labeled witches by the Inquisition were actually just "mentally ill", even though their understanding of the mind and their methods used to "treat" it (torture, mostly) had hardly changed at all.

It's an anti-psychotic that is currently targeted at Parkinson's disease related psychosis; hallucinations and delusions are fairly common in people with Parkinson's disease.
FWIW I was cured of a chronic, crushing depression in a single session that lasted no more than ten minutes or so. (I don't know exactly how long it was because I was in a deep trance. Subjectively it was only a few moments.)
I'm sure they'll tell us for just one easy payment.
Which is to say, it's probably just a simple lie - either one they are telling us, or one that has been told to them.
The seminar cost US$4000 but I only used about ten minutes of it. Best investment of my life.

Ah, story time... I just remembered how I couldn't bring myself to go to CodeCon.
I had a ticket.
I got as close as the corner.
I just stood there and watched my fellow nerds walk up and go into the building for a while and then went home.
(You can't explain these things to normal people. They can't relate. My mom once said to me, "I know you're not faking this because no one would ever choose to be this miserable." which was actually more comforting than you might imagine.)
Anyway, next time, after my depression was cured, not only did I attend CodeCon, but I gave a presentation that went really well, and got my first job as a professional programmer. Literally a guy walked up to me after the presentation and asked if I would be willing to move.
Turns out with out the crushing depression holding me back I'm not too shabby. Yay!

You may have personally been extremely lucky and experienced essentially a miracle.
But what you are claiming is similar to people claiming they cured cancer with healing crystals, or prayed the lupus away. There is no way to take your claim any more seriously: you are either lying or you experienced an extremely lucky break, and were lied to about the cause.
There is no other way to react to people promoting pseudoscience, especially in medicine. Someone else who is suffering could be duped by your well-meaning sharing of this experience into throwing their good money away on bullshit in hopes of reproducing a miracle.
Yes. Exactly that.
(In a sense I did get lucky: Dr. Bandler could have picked someone else for the demo.)
> based on this personal experience,
And a lot of other personal experience, and a pretty good understanding of the formal grammar analysis that spawned it (and that also underpins computer languages.)
> you claim that NLP is not the pure crackpot lunacy that it is,
That you claim it is...
Do you have any experience? I find a common denominator among strident skeptics like yourself is that they have no actual experience and have done no personal investigation. Are you an armchair skeptic? Have you any experience whatsoever with hypnosis or NLP?
> but some advanced, misunderstood
...yes...
> science.
No. Not yet. But it should be.
You insist that I must be a liar or a fool and yet you would prefer a miracle to rational investigation.
Well I'm no liar, but certainly one of us (at least) is a fool.
Good day sir.
You see, this is where you lose me. Chomsky's work has absolutely no applicability to treating mental illness, and he would be the first to explain that. His work is not even applicable to language translation, and has no hope of being in the foreseeable future. It is just a framework for discussing some basics of how human language works and can be learned.
Hell, it's barely applicable to computer languages, where again, it's only a framework for discussion. It certainly doesn't 'underpin' computer languages (the work of Alan Turing, John von Neumann and others does instead).
> Have you any experience whatsoever with hypnosis or NLP?
No, and neither do I with crystal healing, praying the lupus away, acupuncture and a myriad others.
Think back to something that made you angry, that annoyed or frustrated you. Think back to a time where you got really riled up. A time where you were really pissed off at someone.
You're going to close your eyes for 20 seconds and think about it, feel it, really try to go back to that day and immerse yourself in that moment. Now, close your eyes.
Did you notice anything? Did anything in your body change in the last 20 seconds?
By thought alone, you can change your physiology, your mental state, your blood pressure and heart rate. Nothing in your environment changed, you're still sitting here reading this, yet to your brain you were momentarily somewhere else. For me, stuck in traffic and some wanker just cut me off, nearly caused an accident and seemed oblivious to it all. I wanted to crash my car into his just to teach him a lesson. It can make your blood boil just thinking back to past events where you were wronged.
I had you think back to something that made you angry, and you probably felt that same way you did that day but to a slightly lesser degree. If you continue to think about it, think about how wrong it was, you can feel EVEN MORE ANGRY. But you don't have to.
You can think back to these moments in your life and feel less or more of the emotion by altering the memory, or your perception of the event.
Your past influences who you are. Your past only exists as memories within your mind. Memories can be recalled and changed by your mind.
You can think back to past events and change the way you perceive them. That's the practice of NLP from my perspective. Changing your memories so that they benefit you.
All those times you've been embarrassed, angry, frustrated or annoyed, you can look back at these moments and laugh at them. Think about some negative moment in your life and then literally laugh out loud about how absurd it was.
Seeing a memory in your minds eye you can turn the colour down so it's only in greyscale. You can mute the person saying hurtful things, or change their voice to that of a cartoon character, something absurd and comical. While you're doing all this, recalling past events and memory manipulation, you're comparing your emotions and how your body is responding, before and after each change.
This might be something you can learn how to do in one session, but for me it took lots of purposeful practice. Like a muscle you develop, you become better at this over time.
I want to emphasis that NLP "is" lots of different things depending on who you ask. The most important aspect IMO is the act of "going meta-" to your own psychology, learning to "reprogram" your "biocomputer".
It's a fundamental shift. People talk about education that adds facts to your store of knowledge vs. education that changes who you are. Learning to operate your own mind+body changes your self-image in a deep way, and raises the level on which you operate.
What excites me is the possibility that enough people learn to take responsibility for their own thoughts and emotional reactions, and we can collectively get over our shit and make e.g. some sort of cool Star Trek future, where humans are mostly sane and healthy. (And "we can hang out with cool aliens that like us." ~Dude, Where's My Car?)
Since then, except for one (terrifying) three-day period, I've been free from the depression that was ruining my life.
So yeah, like I say, I don't know what he did. (Frankly, in a sense, I don't care. I'm cured! I have a life!) I actually lost interest in NLP after that. I only promote it because it feels irresponsible not to, so many people are suffering needlessly and many of the solutions to their problems are right there if only they knew.
(Even the stuff that made it to education science doesn't work. There's no such thing as a "visual learner".)
As for the "theory that someone just made up." That sounds weird to me, because my experience has been that theory is treated as no more than a prop to support hypnosis. The emphasis is always on the pragmatic and empirical. If you go read the books like "TRANCE-Formations" they are really upfront that they have no idea why this stuff works.
Whatever NLP is, they collected "a bunch of things that do work" many of which no one ever noticed and wrote down before, eh?
No, this is something totally different.
The core of the process is a double-disassociation and a kind of time reversal. You watch yourself watching yourself watching yourself and then play the movie backwards. Somehow that changes, quickly and durably, the way the brain responds (to kittens or elevators or whatever.)
Here's a brief video of Dr. Bandler talking about the background and how he developed it: https://www.youtube.com/watch?v=tGUXQRubBrY
And here's an example: https://www.youtube.com/watch?v=syIXq7e41sY
I wonder if our national obsession with anti-fat dietary advice has had an impact on depression's prevalence in our population. It would seem to make sense that if we depress people with low-fat frankenfoods they naturally react with lower physical activity levels.
I wonder if omega-3 / omega-6 dietary balance changes the structure of the cell membranes to make them less permeable. Greater omega-3 cell membrane composition certainly seems to have a real impact on retina cells and the overall function of the retina[1].
You can get actual healthy yogurt with plain Greek yogurt or skyr, though, it's not hard anymore.
It's still about chemical balance. It's a highly complex system involving more than serotonin, though.
He mentions serotonin reuptake inhibitors once, but it looks like this finding applies to other substances identified as anti-depressants that aren't necessarily serotonin targeting.
Also, if there is a behavioral component to depression as well, then it doesn't necessarily mean someone is to blame for their disorder. You don't control the environment you grow up in, which has an enormous impact even on traits that are highly heritable (the whole subject of heritability is very misunderstood anyway).
So basically if I were going to describe depression's cause, I'd say it's a mixture of biochemical reactions, behavioural traits, and environmental stresses that cause it.
to quote: "Now to the BDNF hypothesis. I used the phrase “unknown mechanism” above, and that’s exactly what this work may have cleared up. The authors show that when the TrkB protein forms a dimer in the cell membrane, a binding site for small molecules is formed at the interface. A whole list of known antidepressants (fluoxetine, imipramine, venlafaxine, moclobemide, ketamine, esketamine, and R,R-hydroxynorketamine) bind to this site at about 1 micromolar levels (and can displace each other in binding assays(, while a set of control CNS compounds like chlorpromazine, diphenhydramine, and indeed S,S-hydroxynorketamine do not. It will not be lost on those who’ve done research in the field that the antidepressant compounds listed above have been thought to work through completely different mechanisms. "
Here's a good journal article on the subject https://sci-hub.st/https://www.sciencedirect.com/science/art...
NHS current website "This type of medication [SSRIs] works by increasing the level of a chemical called serotonin in your brain." https://www.nhs.uk/conditions/generalised-anxiety-disorder/t...
Wikipedia "It is believed to work by blocking the re-uptake of the chemical serotonin by neurons in the brain." https://en.wikipedia.org/wiki/Paroxetine
etc.
If you either get massively technical about complex things that would make most laymen's heads spin, or shrugged your shoulders and said that we don't really know, you might miss on the potential psychological effects that you can get by projecting some kind of confidence.
SSRI's do not increase the pool of available serotonin, they just artificially increase the amount that remains in the synaptic cleft, facilitating additional firing of the neuron (or for a longer duration, I'm not sure which). They do not increase a neuron's ability to synthesize serotonin and release it into the synaptic cleft at the appropriate time. SSRI's cause our neurons to reuse serotonin longer than they normally would, which is not how we evolved to use serotonin.
The way this felt to me as a human interacting with the world around me was artificial happiness and artificial feelings of ease. I felt "better", but it didn't feel like it was grounded in anything real. I felt happy when happy things happened, but I also felt happy when sad things happened. Eventually it wore off and SSRI's no longer had any effect on me.
I eventually tried tryptophan and B vitamins (specifically B6), which our bodies use to synthesize serotonin. I got a similar effect to when I first started SSRI's, but it felt real. I was able to be happy when something happy happened. But when something sad happened I also felt sad. This effect has endured for 4 years now.
I have since found that I had a serious problem with a particular toxin which poisons many of the pathways involved with serotonin synthesis (among many many others including one of the most fundamental, the Citrate Cycle). A way around the poisoning is large doses of the appropriate nutrients. This is because the toxicity causes serious inefficiencies in their use by the body's biochemical pathways.
This was my personal experience. Depression is caused by many factors and I'm sure what works for me would not work for many. It can be genetic issues, other kinds of toxins, and overwhelming amount of trauma, chronic infections, unhealthy relationships, etc. Or a combination of those.
Chronic mercury toxicity was the cause. I've confirmed this diagnosis with dramatic improvement to chelation therapy. I've also done some novel testing that indirectly confirms the diagnosis. It's not something you can test for directly unless you start taking biopsies of tissues you wouldn't want to cut out of someone alive. It resides in "deeper" tissues, not in the blood. The effect of mercury on biochemical pathways has been mapped out quite extensively, and we even know what and why certain genes make some people more susceptible than others. Not something you'll find in mainstream medicine, but the research is extensive and still rapidly growing. Particularly in the toxicology and chemistry circles.
I use a newer chelator called emeramide. It's currently in Phase II clinical trials and will probably be approved within 10 years. Although, it can be very dangerous if someone takes a too large of a dose, and the person pushing it through FDA approval does not seem to be fully aware of how bad it can be. Generally, the sicker you are the lower the dose you need to start on. This phenomenon is extensively documented in the Facebook groups where mercury toxic people discuss their experiences and results.
Emeramide binds to mercury the strongest, but also chelates other toxic metals like lead and cadmium, so those could certainly be complicating factors. Especially lead, as I grew up in a home and neighborhood with lots of it.
As for where the mercury came from, the timeline of my symptoms, animal toxicology studies, and it's removal in 2001, and more, all point towards the vax(inations I received as a child. For example, I had random and inexplicable symptoms as a kid like attacks of projectile vomiting without being sick, and bloody noses that would last for hours.
This FDA Q&A is a good read, although obviously biased against my perspective:
https://www.fda.gov/vaccines-blood-biologics/vaccines/thimer...
The FDA does acknowledge that kids in my generation were exposed to mercury slightly exceeding the established safety limit for oral exposure, but makes no mention as to how it is not appropriate to use an oral limit when the exposure is through injection. Toxicologists know that the exposure route makes all the difference in how toxic a substance is, and it is specifically written into environmental regulations like RCRA. For example, ingested substances are first directed straight to the liver through the portal vein for detoxification before being spread to the rest of the body. Injected substances bypass this defense mechanism. No exposure limits have ever been developed for injection, because the laws are all written for pollution, and people obviously do not inject pollution into themselves. (I was an environmental engineer for several years.)
That FDA Q&A also discusses how there was a lot of concern expressed by healthcare professionals regarding thimerosal, and that's why it was (mostly) removed, but they stress that it was just to be safe, and they have no reason to believe that it's dangerous. To be honest, it sounds like covering-their-ass double-speak to me, and reminds me of how polluting companies handle their coverups. The reality is that these things are so difficult to prove one way or the other, and the liability and denial issues are immense. No one wants to admit to themselves or others that they accidentally poisoned someone. Not just for financial reasons but for their own psychological well-being.
Also, they take weeks to take effect which doesn't make sense for a neurotransmitter effect, since Adderall (which raises dopamine) works instantly for ADHD.
I've heard theories that just doing anything to your brain knocks it out of state enough to stop being depressed (eg psychadelics do this), or that antidepressants actually improve your sleep quality and your brain cleans itself up over time.
It's a re-uptake inhibitor for both serotonin and norepinephrine which keeps your body from flushing our those chemicals which raises serotonin levels as long as production is stable.
High doses of SNRI will contribute to Serotonin syndrome, which makes your argument hard to believe.
But there are effective antidepressants that aren't strongly based on the serotonin effects SSRIs have, like trazodone (weakly increases it) and especially ketamine (doesn't do it, works better than most antidepressants, works near-instantly instead of taking weeks).
See my other comment about the growing interest in the glutamate system instead of serotonin and the like.
This just isn't the case. Maybe the more accurate thing to say is that there have been a few "medical positions" on this issue in the past six to eight decades, and "low serotonin" as well as "we don't know how they work" were both out there in the ether. But even that's not fully accurate, because you'd have to be pretty bold to argue that there wasn't a dominant "medical position" on the matter since biological psychiatry finished supplanting the Freudians for control of the field in the 1970s. The dominant position was the chemical imbalance theory, of which "low serotonin" was one of several variations trotted out over the years to both the public and the medical community.
Psychiatry is one of the medical specialties most profoundly co-opted by pharmaceutical industry interests, and both research and clinical practice have been rife with the effects of this influence. You don't even have to appeal to systematic analyses of how profoundly poor the quality of psychiatric research is, or how much pharma ghostwrites those studies, or anything of the kind. You can just ask a researcher in cancer or in neurology; they'll happily tell you.
To cleave the "medical position" from "marketing", as in your comment, elides what really happened: marketing decided what the medical position would be, and both doctors and the public mostly bought it.
Alcohols are produced in your brain naturally and adding more changes behavior. Clinical trials show that more alcohol increases sociability compared to placebos (but with side effects). There are some concerns about giving alcohol to three year olds, but it is better that they become socialized at a young age than deal with the consequences for life.
In short: science + tons of money = not science.
"Given the effect of antidepressants on the glutamate system, there has been a growing interest in the development of pharmaceutical agents that might modulate the glutamate system. Ketamine is a potent, high-affinity, noncompetitive N-methyl-d-aspartate (NMDA) receptor antagonist that has long been used in anesthesia and is a common drug of abuse in some parts of the world."
Novel antidepressants now are NMDA receptor antagonists, or take a look at tianeptine which works just as well, yet it only affects your opioid receptors. None of which have to do with the monoamine hypothesis.
Quoting directly from the article
> Despite decades of research, the role serotonin plays in depressive phenotypes has not been conclusively determined. The original clue that monoamines (serotonin, norepinephrine, and dopamine) were involved in depression came from two serendipitous discoveries (Baumeister et al., 2003; Valenstein, 1998). First, during the investigations of iproniazid as a treatment for tuberculosis and imipramine as a treatment for schizophrenia, clinicians reported that these drugs could reduce depressive symptoms. An effort was then made to find a common pharmacological property that could explain their antidepressant effect. Eventually, researchers found that iproniazid inhibits the enzymes that break down the monoamines, while imipramine blocks the serotonin transporter (SERT) and the norepinephrine transporter (NET). Second, clinical observations suggested that reserpine, a drug known to deplete monoamines, increased depressive symptoms. These findings appeared to solve the puzzle. By preventing the breakdown of norepinephrine and serotonin, or preventing their clearance from the synapse, iproniazid and imipramine appeared to increase forebrain monoamine levels.
> The monoamine-enhancing effect of antidepressant medications (ADMs), coupled with the depression-inducing effects of reserpine, suggested that depression was caused by reduced monoamine neurotransmission (Everett and Toman, 1959; Jacobsen, 1964; Schildkraut, 1965)

Additionaly, this is something that lots of undergraduate psychology textbooks still mention as a potential explanation (one of mine did ~6 or 7 years ago, although at least they said that it was an implausible theory).
Second: statins inhibit cholesterols so while it is associated, it's good to mention that cholesterols are anti-depressive, which is something anyone with any university bio education will know.

The last time I had it was a bad night - I took about 7g.
However, the suicidal thoughts that had been getting progressively more serious stopped overnight.
I'll never touch another fucking SSRI. I'd rather not exist at all than become the unperson those things turn me into.
I really do want not to die, and I see a viable path forward with that as a result.
An illegal and seasonal path.
I last took a dose in July, and those malignant fucking thoughts are returning.
And nurses keep telling me that psilocybin clearly has not worked (all the while advocating a pill a day, pill a day, pill a day).
If you see a drowning man take a gasp of air, and the keep right on drowning that does not mean that the air did not work.
The system is fucked - but try not to let it eat you.
Unfortunately psychedelics I’ve tried just up anxiety and paranoia. My last experience had me crouched up on the couch alternating between sweating and chills, hating the time dilation and just waiting it out.
The only possibility for getting around the seasonalilty is growing indoors - and I really don't have the space for that.
Depression for me has caused me to spiral down - so far down that there's no apparent path back up.
I've been down and out for so long that even finding work is damned near impossible - so I can never even get to the point where renting my own place is feasible.
My next experiment pending warmer weather here in MI: a hunt for wild psilocybin mushrooms. I’m convinced the best way to achieve my goals is to rewire my brain with psychedelic experiences.
While this primarily has to do with psychedelics, they address depression as well in the above.
It's often said depression is natural, and it only becomes a problem because of sedentary lifestyle.
Diseases are bad, but when you dig, nature doesn't work in term of good or bad. I think it's difficult to really know at what point depression becomes problematic, since doctors have a hard time making a good diagnostic. Brains are complicated.
Sorry what was that? You're breaking up. I'm off to the store, ttyl.
(Do people who like bacon know they can just eat chashu?)
A common mechanism of action may have been found across antidepressants where none was found before. This common mechanism between both Prozac and Ketamine has some impacts on how cholesterol is used in the brain and BDNF (neuron survival and growth regulator).
"But don't inflict your laziness on the commons"
So you must be against the downvote mechanism as it's a lazy, near effortless way for people to get a hit of dopamine vs. your qualitative response that actually shares thoughts that I am more likely to respect and take note of?
