Essentially these guys try to stay up for the first few days and then sleep less than 8 hours after that. Way less. Many of them end up hallucinating by the end, and only their extreme fitness levels probably save them from just dying from lack of sleep.
The trick is that waking up to daylight makes you feel more rested. So the teams would have their riders sleep 2-3 hours from just before dawn until dawn so they would wake up to sunlight. Physiologically the difference is small, but psychologically it’s much bigger.
Some of the effect of power napping is likely the same sort of trickery, just as caffeine is partly trickery and partly adrenal.
The only marathon I ever did was cram for a couple finals and playing computer games between them and after. I was working on 72 hours when the blue on my monitor started to ripple and decided it was time to go to bed… almost an hour after it started.
Is that actually a thing, rather than just hearsay?
And in particular if you abuse epinephrine enough. Caffeine blocks the sensation of fatigue, epinephrine does it even moreso, and up until I was in college, when my roommate told me about it, could be purchased from truck stops as an “allergy medication” but truckers use it to pull double shifts. If you keep taking it you will feel fine right up until you keel over.
South Korea has places you can rent a computer. Some are 24 hour. There was a case a while back where a middle aged man stayed awake for around 50 hours and died at his computer. Officially he died from lack of sleep.
https://en.wikipedia.org/wiki/Recovered-memory_therapy (see research section)
If it happens in therapy, that doesn't mean the memories are "implanted". And not all memories lack the ability to validate them... for example, if you've forgotten someone's name, then remember it later, you can call out to them by their name to confirm that you've correctly remembered it.
Memories tumble around in the brain all the time, not all memories are easy to access, but that doesn't mean they're inaccessible.
The point that memories can also be implanted or fabricated during therapy is absolutely an important one, but dismissing the possibility for memories to resurface (and conflating any situation where this might happen with a specific type of discredited therapy) is needlessly reductive.
Yes, witness testimony is always potentially flawed.
But knowing "some repressed memory recovery is false" does not justify saying that repressed memories are not a real thing. Repressed memories do happen. They do come back sometimes. When they do, they are just as valid as any normal memory that a person thinks they always had.
I know because I had them myself. Mine were of trauma in the age range from 5-9. I had a high "ACE score" when I eventually looked into this. I did not have any therapy session prompting the recall, I just remembered them spontaneously around age 15 when I was empathizing with a schoolmate who told me about domestic violence. It was a sickening feeling to have this whole phase of my past come unlocked.
Amazingly, it submerged into repression again. I next remembered it at about age 20. In between, I had years of basically not remembering/knowing that I had any of this trauma or that I had experience the earlier recall. They all came back together, again triggered by an empathetic moment in college. Again it was disorienting to have this whole aspect of my past reopen.
At that later point, I confronted people who were around my childhood and got enough of a painful discussion, confession, and apology to know that these memories were not invented.
I had other forms of childhood trauma that never submerged. I don't know why this one section did.
I find it very offensive for someone to make broad statements that these phenomena do not exist.
If it takes long, intense therapy to "bring back", it's almost cerainly untrue or falsified. There was a case of accused childhood abuse among close relatives of me, by someone who found out about this in therapy. It tore apart the family. I cannot take any sides because I was not there and cannot know the truth, but it checks all the boxes of falsified memories. It has destroyed multiple lifes. That's how I even learned about that stuff, and why I care.
Btw, better source: https://en.wikipedia.org/wiki/Repressed_memory (I originally mostly read stuff in my native language, so I didn't what to look for initially)
The thing that changed though is since the 2010s everyone has a high definition camera in their pocket. Everything you do is recorded online. Kids that grew up in the last few years will have their entire childhood recorded in some way or another. Every movement tracked by GPS. Therefore, while I don't agree completely, I wouldn't be surprised if some assumptions about psychology are upended and a great deal of so called repressed memories turn out to be bogus when we can easily disprove them.
This whole thread is gross. I’d say you should be ashamed of yourself but you likely lack the prerequisite self inspection.
Yes, real life is messy and ideals like justice are quite difficult or impossible to achieve.
Don't assume you can cleverly deduce a nice, absolute and comfortable answer. That's just another coping mechanism called rationalization.
When such memories come back, it can be like a mini identity crisis. You suddenly know things that are counter to your self-identity from the moment before. Once I was able to absorb the whole picture and not recoil back into repression, it became a permanent and unpleasant part of my self. .
There can be flashbacks of related events, some of which I also might feel are remembered for the first time in a long time. Those little flashbacks might be like remembering your specific uncomfortable cafe. The overall memory recovery is like suddenly realizing I spent years in a theater of war, that happened to have such cafes in it.
the craziest one I had, my reaction wasn’t “oh my god i never knew i had this memory” it was “wow, i cant believe i havent thought about that in 25 years.” I knew and had known it was there all along, I just literally never thought of it to the point my other thoughts just didnt collide with it, ever. It’s almost like your brain just puts it in storage in a dark corner of your garage.
I understand it isn’t the same for everyone, but that was how it felt for me.
TLDR for me it was dissociation, and the only treatment that ever worked was scraping the corners of my mind for stuff like this and it got so much better the issues basically went away. I used a great deal of meditation, particularly tibetan buddhism.
The comments in this thread are indeed disturbing. Clearly many on this forum have led blessed lives and can’t imagine people having it differently,
Like, if kissing is derived from impulses relating to breastfeeding (which is a hypothesis that, AIUI, is in good standing, though not the only one in good standing nor necessarily more favored than a couple others), I wouldn’t think that therefore someone who was only ever bottle-fed as a baby would therefore not get anything out of kissing. The appeal of “my lips on another person” should be there regardless, just as it was for the first time a baby is breastfed (though, of course, it is also a cultural thing: not all cultures have had kissing as a standardized way of expressing affection, so whether one grows up in a context where kissing plays a role, that probably also plays a part in whether one finds it appealing to have one’s lips on another person).
The idea of "repressed memories" was that people had hidden memories that they couldn't access, even if they tried. According to the theory, even if someone brought up the past event and tried to remind the person about it, they would be unable to recall it happening because their brain had blocked it out.
The idea was that only intervention by a therapist or some other special event could help the person "unlock" the repressed memories, making them available for remembering again.
What was really happening was that some therapists were leading people into "remembering" things that didn't happen through aggressive prompting and pushing, much like what happens when an aggressive investigator convinces a vulnerable person to falsely confess to something they didn't do.
Other things about that day were surfaced. How my braces felt and the fear I felt about forgetting a textbook.
All real, but unsurfaced until then.
If you hear the first tones or words of a song you're much more likely to be able to tell the lyrics that follow compared to being asked to say those lyrics based on the title.
It is specifically about trauma, and generally you don't forget traumatic events and that's often a big part of the problem. We are not talking about trivial things like the name of your maths teacher in high school, which have a tendency to come and go.
It is also specifically about therapy, that is an environment where you are actively encouraged to recall memories. We know how easy it is to make up memories, especially with the help of a third party (here, the therapist).
Combine the two: memories that are hard to forget and an environment conductive to making false memories and it becomes very likely that the "lost" memories are completely made up.
Oh, of course you can.
That depends on how many you endured really. Only so much room in the old noggin with everything else important going on.
Some of the techniques included hypnosis or even giving the patients (including children) sedative-hypnotic drugs before pressuring them with the leading questions.
If they could eventually get the person or child to claim to have some memory of the event (after asking a lot of leading questions and maybe even drugging them) they considered it to be a recovery of the memory.
On top of that, I have legitimate memories that were not traumatic, but still related to the same traumas because said person attempted to encourage these activities throughout my young life on rare occasions. I didn't remember what happened as a kid, but I knew something wasn't right and I wasn't comfortable. It wasn't until I was almost 30 that I had my first "flashback" which was a fractured memory, I still remember it looked like a faded photograph in my mind, and it was accompanied by an extremely uncomfortable feeling.
The re-surfacing memories aren't real in a sense, but in my case they aren't entirely fake either.
I wonder if it's possible that things can be completely imagined with absolutely no basis what-so-ever in certain circumstances, and I also wonder how difficult it is to discern that. It seems to be a difficult concept to manage.
On the other hand, I do have some Gandalf "I have no memory of this place" moments for other things.
Though you're right - a specific scent can easily call up an ancient, forgotten memory.
I'm reminded of the story of dragon sightings in Great Britain: after the printing press and newspapers and newspaper reporters chasing stories emerged, as news distribution out from city centers into rural areas increased, it seems dragons picked up and moved farther away, only being spotted in the hinterlands without news.
You apparently would keep your mind open to the idea that dragons don't like the smell of newsprint as no other conclusion could be more plausible sheerly on the basis of logic?
One remembered memories of a WWII pilot named James Huston Jr. and the other a deceased Hollywood agent named Marty Martyn.
Putting aside the reincarnation hypothesis for the moment, do you think the kids invented the details and coincidentally happened to match to a real person or were they fully coached? Maybe they didn’t get enough sleep or got too much sleep?
It might be something that one might not understand if he/she doesn't live through it I guess
You're saying that those memories are exactly the same as all the other memories.
Every time you "recall" something, you are not pulling up some file that is always the same. You are actively recreating the memory.
There's nothing "fun" or insightful about this, this mechanism has been known for a long time.
Obviously it's not unique to psychotherapy.
> may have been created
Most things that "may" have happened do not warrant absolute statements such as "that's not a thing" (which, incidentally, is a particularly empty statement in any context, since every thing is a thing)
Proof: "colloidal silver has been used to attempt to cure cancer".
Solid logic.
Some of the techniques used in the therapy include giving patients sedative-hypnotic drugs to put the patient in a waking dream-like state while the therapist asks leading questions to get them to "remember" an event. The same drugs they used are known to be associated with false memories, like when someone falsely recalls something from a vivid dream as having actually happened.
I am not advocating for it, just stating the near total lack of substantive scientific evidence presented either in support or opposed.
demanding citations is the favorite trick of people who want to waste your time precisely because they disagree with you and no matter what you come up with, they'll never give in. therefore, one should never give in to it.
rather, doing your own research and contributing it to the discussion is the lifeblood of online communities.
Sometimes yes, created to validate, sometimes no, unlearns to disassociate
Once a memory lapses you have to relearn from life experience (or not at all).

> at the first news of English ships in the area, Buckley rushed to the spot. He attempted to make contact, but couldn’t swim out to the ship and couldn’t convince the ship to send a boat to him (Buckley had, at this point, forgotten how to speak English.) Buckley was again heartbroken until another ship showed up, and he found the English colonists and tried to approach them:

Once I was in a Toys-R-Us and noticed a cover image among the bottom-of-the-barrel DVD display which caused me to put what I was doing on hold for several minutes while I stared at the DVD. I bought it, and it turned out to be a movie I had watched many times when I was very young, but that information hadn't been accessible to me.
Every memory your brain has ever produced is still there, even if most are beyond conscious access. Memories quite literally become a permanent part of you.
A lot of people mistakenly think of human memory as a sort of hard drive with limited capacity, with files being deleted to make room for new ones. It's very much not like that.
If you just mean that human memory has a finite capacity that's much larger than anyone has come close to reaching by storing the memories of a normal human lifetime, that might make sense.
Do you have any references for your statements about memory? I'm not familiar with whatever science there is in this area.
Consider an exponentially weighted moving average - you can just keep putting more data in forever and the memory requirement is constant.
The brain stores information as a weighted graph which basically acts as lossy compression. When you gain more information, graph weights are updated, essentially compressing what was already in there further. Eventually you get to a point where what you can recall is useless, which is what we would consider forgotten, and eventually the contribution of a single datapoint becomes insignificant, but it never reaches zero.
It implies enough capacity to store everything. But what you describe is not storing everything.
> lossy compression
Which means you're not storing all the information. You're not storing everything.
> When you gain more information, graph weights are updated, essentially compressing what was already in there further.
In other words, each time you store a new memory, you throw some old information away.
Which the person I was responding to said does not happen.
If you have questions about my comment, I'm happy to try to explain myself better
"I didn't understand you at all, so you must have meant either A or B" is not the way to reach an understanding
I didn't ask for that. I asked if you have references for what you said. Even if I misunderstood you, that shouldn't be a reason for you not to give references for your statements, if you have them.
If you don't have any references to back up your statements, then I'm not sure what you're basing them on.
How would that not imply infinite storage?
It is almost certainly false, but it doesn't require infinite storage to be true.
Which would put it into the category of the second part of my comment--which the person I was responding to said was not relevant to what they meant.
True, but it doesn't really detract from his statement because do we really know what that upper bound even is? I don't think we come close to the theoretical storage limit... So saying "every memory you have is permanently stored" is effectively true, at least true enough for a thought experiment like this. Perhaps when people live to be 200 years old and we know more about the brain we can test this, though.
I used to be weary of learning new, complex things, thinking I'd "lose" old knowledge XD
That was the point of the second part of my comment--which the person I was responding to said was not relevant to what he meant.
Memories seem to be constructed by a group of neurons together, and it seems clear that neurodegeneration is a thing, whether by trauma or due to aging. When pathways degenerate, maybe you have a partial memory that you brain can help fill the gaps with(and often incorrectly), but that does not make it the original memory.
The way I understand it, it's just that, unlike on disk, the deletion process is not binary. Weak connections that are not revisited regularly gradually become weaker, until they're undistinguishable from noise (false memories).
I don't know where I got this trick. Likely some survival show or some novel. But I don't have any background in survival, otherwise, I would have brought a lot more water.
So my brain knew there was a memory that could help and made up a dream about it is my theory.
My wife still has to work 24 hour shifts with no sleep, performing emergency surgeries no matter how long it has been since she slept. During residency only a few years ago she and her co-residents were almost weekly required to do 36 hour shifts (on top of their regular 16 hours per day, 5 day per week schedule) and once even a 48 hour shift when the hospital was short staffed.
Of course I’m sure they won’t. No one cares if doctors are over worked.
Yes, a tired doctor sucks. But a tired doctor who already has the patient's state loaded into their head may still be better than doctor who is completely fresh in both senses.
It's a hard problem.
I’m sure cases exist. But I’d be rather surprised if they’re common.
12:00am - 6:00am: Doctor 1 and Doctor 4 are doing everything together.
6:00am - 12:00pm: Doctor 1 and Doctor 2 are doing everything together.
12:00pm - 6:00pm: Doctor 2 and Doctor 3 are doing everything together.
6:00pm - 12:00am: Doctor 3 and Doctor 4 are doing everything together.
This way, all 4 doctors only do 12 hour shifts, and the patient's state is maintained continuously through all 24 hours.
Doctors are also unlikely to want a 50% pay cut in exchange for shorter hours. They aren’t directly exposed to the risk caused by fatigue since they will have malpractice insurance. Therefore the safer method of care would be simply too expensive, and doctors wouldn’t see an upside.
Part of the shortage is a result of artificially constrained supply as there aren’t enough med school seats to keep up with demand.
1. Shortly after, a doctor A came in, asked some questions, looked at the chart, and told us she was having the baby tonight. Holy shit our life is about to get crazy and we're going to be parents 2+ months early! He leaves.
2. Several hours later doctor B comes in. We ask about delivery. "Oh, no. You're not going to have the baby now. But you will have to be on bed rest until the due date." Jesus, my wife is going to have to quit her job.
4. Even more hours later, now the next morning, doctor C arrives. "OK, you're free to go home. No bed rest needed. Just let us know if anything else happens."
My general experience with doctors is that you get as many unique opinions as there are doctors in the room. This is not an indictment of the profession. Human bodies are insanely complex, there is way more variation between them than most people realize, and doctors are operating under very very limited time and information.
Having overlapping doctors would likely cause even more patient confusion and increase the risk conflicting treatments. Also, it would obviously double the cost of care.
(My wife and baby were fine. Partial abruption. Very scary and my daughter was born five weeks early, but no other significant problems.)
(not defending, I also think its insane, just devils advocate)
The world doesn't run on boolean logic. A solution can improve an issue without solving it completely.
AI fixes this. Imagine the boot time of loading a patient's state from dozens of labs and files vs. a summary that gets you to exactly what they're going to end up remembering anyways. And if a doctor finds something interesting that the AI doesn't flag, they should be flagging it in the chart for the next doctor anyways.
Your solution to information loss during doctor handover is to insert a brainless hallucinating program with zero responsibility into the middle?
This would not appear to apply to emergency surgeries. They aren't done by doctors who are familiar with the patient anyway. (Neither are non-emergency surgeries. Surgeries are done by doctors who do that kind of surgery. Familiarity with the patient is useful in deciding what surgery should be done, but not in doing the surgery.)
Doctors boards and AGME (partly governed by AMA, but there is some amount of public representation) control residency admissions and board certification. We don't necessarily want low admissions standards, but there is a lot potential conflict of interest in constraining supply.
Some states, I think I read Florida recently, have started pushing back to allow in foreign doctors.
I do think it's maximially optimized to extract revenue. That can sometimes be good (e.g. good access to healthcare) but often times it's not great.
Given healthcare, along with education should be a national priority, both should be heavily "configured" to serve peoples' goals first and any financial goal should be secondary (although arguably useful).
I suspect the current shareholder structures from hedge funds are (intentionally or not) driving things in the wrong direction wrt to public health goals. This is article from a few days ago is also interesting https://news.ycombinator.com/item?id=45680695
If you were driving a truck in EU, you would have several mandatory 8h stops by then.
if you get through and into a good med school -match into surgery- you are Peak in a way very few are.
I don’t see this changing unless they reduce the requirements for med school; if they let anyone in who wants in and force that group to work 30hr shifts - you’ll get enough bad outcomes the system will change.
There was a study, I believe on nurses and shift durations. The study found the nurses were happier with shorter shifts - but the patients did worse. Patients come first.
I could see a group of Doctors loudly proclaiming love for Donald Trump (and mentioning very much how great he is) and pleading the case for a change and something happening. He is an interesting president.
I would be interested in hearing a european drs perspective, I heard they work shorter shifts (but no EU dr I met has confirmed, it’s like meeting a unicorn)
A fraction of a fraction of a percentage of people are good at surgery.
If I need someone cutting me, I’d prefer someone good, and that they were rested.
I don't think what I said would come across this negatively in person though, but okay..
Reads like being more or less forced to me, it doesn't to you?
> and why the personal attack?
Not at all my intention! It's a genuine question, which I would ask myself too were I in OP's shoes
Imagine doing your best to help someone and they die as a direct result.
Then you get to go to work and deal with the next case.
Or the patient has life changing, negative outcomes. Damn, that bad. Next case.
Living in that mental state takes a pretty unusual character type. We can expect some extreme behaviour.
It’s also interesting watching the change over time. The trainee versus consultant, or the surgeon as they near retirement.
I’m not a surgeon or a doctor and so I see a small part of their world but see some of the perks (they get everything) and some of the downsides, and there are a lot.
> Lewis and colleagues showed that CSF flow during sleep follows a rhythmic pattern in and out of the brain
> Most significantly, they found a flux of CSF out of the brain just as those lapses occurred. After each lapse, CSF flowed back into the brain.
I can't believe the authors of the article didn't address one of the most obvious questions: Where does the CSF flow to and where does it flow back from? It's not like there are pipes leading out of the brain, or the CSF will just leave my brain through my ears or anything, will it?¹ What happens with the waste products? (¹ Though it would be kinda funny if this was where snot comes from.)
EDIT: Wikipedia's got the answer:
> Clearing waste: CSF allows for the removal of waste products from the brain,[3] and is critical in the brain's lymphatic system, called the glymphatic system. Metabolic waste products diffuse rapidly into CSF and are removed into the bloodstream as CSF is absorbed. When this goes awry, CSF can become toxic […]
There are, in fact, “pipes” leading out of the brain. Cerebrospinal fluid is (and this is probably somewhat oversimplified) produced from material in the bloodstream in the ventricles in the brain, flows through the system of ventricles and then out of the brain into the subarachnoid space around the brain and spinal cord, and is then reabsorbed into the bloodstream.

This is specifically the area we work in traditionally called slow-wave enhancement which is stimulating the restorative function of sleep.
This paper [1] specifically looks at amyloid response as a result of stimulation and shows a corresponding relationship between stimulation response, amyloid response, and memory. I wouldn't say it's putting a bow on the results, but it is a very promising result.
If you're curious about what we're building, I'll be posting a ShowHN next week which dives into some of the data in a way regulatory requirements don't permit us to do on our website, but until then, check out https://affectablesleep.com
Long-term particularly if we can make the numbers work for a monthly subscription, it makes the technology more accessible.
In the past, subscription models were understood as a way to offer "loyal customers" a "better deal" than the standard alternative. They were a method to entice "loyalty", not a dark pattern to enforce "lock-in", continuous cash-extraction and control by artificially crippling a product. I've watched too many a product introduce unnecessary "restriction-features" or an artificial need for consumables, for the sole purpose of a "greedier" revenue stream, so the immediate reaction when I see such products now is one of scepticism.
If you offered an oldskool "expensive" non-subscription, no-internet-access-needed, lifetime-access-with-updates or pay-for-updates model alternative that made sense to non-perpetual users (even at a higher price compared to the subscription alternative), then I would have had more faith in the subscription argument, but as it stands I do not, and would assume most of your customer base doesn't either. They just put up with the "no-real-ownership-plus-overheads" model until they don't have to. Which also implies a very real expiration date for your product, and I'm sure there's a "reluctance tax" your company pays for this effect.
If you offered subscription as an alternative to the full purchase, but the customer could apply their subscription to count in some manner towards the full purchase at a later date, I'm sure you'd get a larger number of more willing and more loyal customers.
Though I agree that some companies currently use subscription as continuous cash extraction strategy, but that's not us.
The reason SaaS is successful as a strategy is because it lowers the barrier to entry. Software which used to cost hundreds of dollars is now tens of dollars a month, and more people are willing to get on board with that.
As mentioned, we did offer a one-time option, in response to complaints about subscription, and we got zero sales. Even from the people who said "if this wasn't a subscription, I'd buy it".
When looking at our business model, there were a few things we considered when deciding on subscription.
1) The hardware is going to change and improve rapidly over the next few years. We decided to keep the price of the hardware fairly low so the upgrade investment is low.
2) As mentioned the one-time fee didn't sell, likely due to sticker shock. We've seen a few other companies in our space try this before, and they've all failed. Those failures are not only due to pricing, but I think it had a significant impact.
3) As unit economics improve to the point we can offer a monthly subscription as a starting point, that really makes this technology accessible to a wider audience, and particularly to some groups who need it most.
Our headband provides sleep tracking technology without a subscription, we're just not selling it as that right now, as the value, we believe, is in the improved sleep and health outcomes.
We look at the stimulation like an app that is running on the device, and it's just the first capability we are providing. We'll be expanding that offering in the future.
With your last sentence, do you mean a "rent-to-own" model? I'm not against that at all, but I'm not sure that really works today, or how we would explain that. It isn't common anymore, and I don't want us having to explain the business model to people being the barrier to sales. Which is why removed the full price option. Each decision point in a purchase causes friction.
How do you know that?
However, I also mis-stated that. It is possible to create a slow-wave, however only through magnetic stimulation (rTMS), but that is not realistic outside of a hospital environment.
You will probably say no but I wonder if those yogis who can exert some control over heart rate, blood pressure, and breathing pattern might try to target this process as well.
What blew my mind when I got into neuro just over 5 years ago, is that the glymphatic system was only discovered in 2012!!!! We have SO much to learn about the brain.
The fluids have no chance to not be flushed once you are done with it.
It seems likely that you'll get those flushes right after falling asleep, so a nap of a few minutes could help a lot.
In my experience, after a night without sleep even a 30 seconds nap reinvigorates you significantly.
If you have 15m, search this on YT for a guided practice and test it yourself.
However, it is very, very fragile to any kind of interruption, so they stopped looking into it.
The video (?) was related to clearing of plaques from the brain with a view to mitigating Alzheimer's effects.
It was not the NSDR (Non-Sleep Deep Rest) videos a sibling commenter posted.
I'm not convinced that the screen nor the headphones are actually providing the required rates.
In the experiments they appear to use a large (c.1m^2) light box so the patient can watch a video from a tablet placed in the middle.
Reading your link made my brain 'resonate' in an unpleasant way; perhaps an auditory memory of watching the video.
All very interesting.
I pop up 5 minutes later and feel completely refreshed.
My experience after sleeplessness nights is that even few seconds help significantly, especially when you're almost unable to function anymore.
If the nap lasts longer than 30 minutes, though, you have a good chance of feeling groggy afterwards.
When I owned some property out in the country, it was a 2 1/2 hour car trip to get there. Sometimes I just couldn't finish the drive home but pulling over to the side of the road for a 10-minute nap made me feel fully refreshed.
I pretty much wait until I feel drowsy, and then take a 15-30 minute nap

2. > Because the doctor will rigorously apply artificial and unreliable diagnostic categories backed up by invalid and arbitrary screens and queries to make a diagnosis. So after this completely subjective and near useless evaluation is completed, your doctor should be able to exercise prudent clinical judgment to decide if Ritalin could be of benefit.
What else can you do for psychiatric conditions? We don't have a magic ADHD-o-meter but know that it statistically impacts lifespan, health, etc. Even for more objective measures like blood glucose, BP, BMI, clinical interventions are based on discrete thresholds that don't exist in nature.
There is such a thing as state-dependent memory or context-dependent memory: recall is better when the environmental context (e.g. location, lighting, smells) matches the context of learning.
If you study while on Adderall, which alters your neurochemical state (increasing dopamine and norepinephrine activity), you may recall that material more effectively when you are in the same neurochemical state, that is, also on Adderall.
Similarly, if someone learns something while sober, they will generally recall it better when sober again, rather than under the influence of a drug.
It is the phenomenon where memory recall is improved when the internal physiological or psychological state matches that during learning.
That, or maybe try a laxative.
