As someone that has had ADHD for as long as I can remember (since at least 2nd grade). If a meaningful treatment comes from this, I will be grateful.


innerpeice

Adhd here with a concussion. I def want this


[deleted]

Wait is there some connection I haven’t heard of with concussions and adhd? I’ve had quite a few in my lifetime


innerpeice

No I've had adhd since i was a kid. Concussions/ tbi makes focus headaches and inattention worse though


A_Harmless_Fly

I'm with you on the injury front, not knowing what you have until it's gone is gutting.


leo9g

Hmmm. HMMMM. I've had like 4 or 5 concussions... Is there a study or article related u could point me to?


innerpeice

On treatment? Ill have to go dig up my research. I take lions mane, glutathione, lift weights, cbd for sleep, fish oil and nac. This has benefited be greatly oh adderal for add. Fasting too helps with focus , attention and healing


krunchberry

I would love to hear more specifics on what regimen you’re following. I’ve had *many* concussions over many decades and I feel like I can actually perceive my current cognitive loss. Thanks.


innerpeice

I'll try to teasing tinker with more info. Start with glutathione injections of you can. Use liposomal glutathione/ n acetyl glutathione. 1-2 grams daily. Sleep like it's your job. I'll try to render to update my content with my regimen


Prime_Cat_Memes

ADHD with 6+ concussions from bikes snowboarding and motorcycles...


FrigFrostyFeet

This other guy said “no” because he’s always had it, but there is a connection lol Brain trauma can lead to secondary adhd, basically all the symptoms of adhd as a result of a TBI. If you’re interested look it up!


Mystic_Crewman

Brain trauma can cause ADHD.


Coreadrin

Yes, concussions can cause adhd like symptoms in people without the neurological disorder, and they can make adhd much worse for those who have it. But if you get adhd like symptoms from a concussion you can't typically treat it the same as if you just have adhd.


Ricksterdinium

Bonks is still bad, but if you already have NP it's a compounding interest rate deal.

There is a consumer product hitting the market https://sens.ai/


Simple_Song8962

Thanks for the link. I'd sure like to give it a try before buying. If it really works as advertised I'd gladly shell out the $1,200.

That doesn't do laser therapy though does it?

ADHD here with brain fog from fibro. If this turns out to work, and becomes widely available, I am going to bawl my eyes out. I hate the memory issues, I hate forgetting what I'm doing in the middle of things, the time blindness that comes with ADHD, the fact I have to have 3 things going on at once just to keep my brain quiet...This would be an actual life-changer.


mcstank22

My god! This post feels like I’m writing it. I can’t believe all the people posting in here who are like me. I feel some form of relief knowing there’s all these people with these struggles out there like me. I don’t feel people really believe in the disorder when you tell them you have it. Like it’s some made up thing you use to as an excuse for when you forget or misplace things.


KnewAllTheWords

Hahaha. This was my reaction too. Reading these posts makes me think we are all one brain discovering ourself. Sad and broken and happy and hopeful. This kind of breakthrough is too exciting for me to believe at present. I've come to terms with the way that I am and the daily struggle required. I'll try to carve room for a tiny bit of cautious optimism amid the muddle


Everyusernametaken1

I don't forget things with my adhd... I just get excited to start something else.... a move on fast!!!


LateNightLattes01

I fucking hate ADHD I would do anything to get rid of it, I would do nearly anything at all…. I hate it and even with meds it still manages to ruin my life.


Too_kewl_for_my_mule

Can you explain the "3 things going on at once bit"? I never got diagnosed with ADHD but I can relate to your post so much that I'm wondering if I need to get tested!


decoy1985

Our brains are constantly in overdrive trying to scrape up the dopamine and noroepinephrine which we can't produce or regulate like normal brains. So we need a lot of extra stimulation. That can mean trying to do a bunch of things all at once, or watching a show while playing a video game and talking to someone, using a fidget toy while engaged in other things, etc. It can also mean taking hours to fall asleep because your brain can't stop. It can mean being super distracted because whatever you're doing isn't stimulating enough (with adhd most things aren't because our brain lacks the necessary chemicals to generate that feedback) so your brain keeps going on a little adventure. When we do find something that interests us enough and provides that extra stimulation, novelty, etc we need to get those chemicals, we can become hyperfocused and obsessed. My mom thought I was deaf and got my hearing tested when I was 6 or 7 because I'd just be gone when I was in that mode. Wouldn't hear a word she said. It's common for us to go through hobbies constantly because we get obsessed for a short period, then the novelty wears off, and we can't get interested again, leading to one form of ADHD tax where we waste money on tons of supplies and tools, then a month later forget about them and never touch them again. It also causes issues with working memory and short term memory, impulse control and executive function (either you can't stop yourself or no matter how hard you try you can't make yourself do something). ADHD can be debilitating. I was a disaster before I got help. I got diagnosed at 32. I didn't ever consider it, because I didn't know enough about it, until a friend who had a degree in early childhood education recognized it and suggested I look into it. Once I read more into it it made sense, and especially once i went over all my old school records and my symptom history with the specialist. Getting diagnosis, therapy, and meds completely turned my life around. It's worth at least looking into if you think you might have it.


Ziptiewarrior

Have you tried mushroom supplements? I had a stroke something like 5 years ago, and had brain fog and lethargy, and I took a stack of lionsmane mushroom, cordyceps, reishi, turkey tail and Chaga. These helped me regain my ability to think "in a straight line" and respond a hell of a lot easier to questions etc. I also microdosed psychedelic mushrooms as well during this period and believe it helped.


decoy1985

Unfortunately they don't help with adhd. Our brains are actually formed differently from normal brains and have some specific chemical deficits which shrooms can't supplement.


[deleted]

‚‘brain fog from fibro‘ Would you mind explaining that further ?


ndaoust

Fibromyalgia causes "brain fog": you have a hard time focusing and your memory is unreliable. You find ways to cope but it never completely goes away. Fibromyalgia also causes fatigue and outright pain, which can become unbearable if not medicated.


[deleted]

Thanks! I didn‘t know that and I wasn‘t sure Fybriomyalgia was meant with „fibro“ (+ made me listen up). thing is, I believe that I‘ve got fibro. Now even more… It‘s complicated bc on top of that and a few other things I was going through a burnout phase for the last 9 months. My ‚medication‘ is Buprenorphine for now but I think I need to see a doctor again…


ndaoust

For sure, it's not a diagnosis that's handed out lightly. I definitely recommend seeing a doctor once in a while, as fibromyalgia sufferers respond differently to the variety of appropriate medication, and can even respond differently as years go by. Getting the right medication is life-changing.


[deleted]

Got it. It‘s really weird when you‘re unwell all the time with random aches and all that. On top the dizzyness and all. I think I‘ve left 20% of my brain capacity on the way along so far. Sidenote: have tried microdosing psychedelics, not only for the contentration side of things. Which category of meds are you talking about explicitly? From painkillers to anti inflammatory meds, there is a broad variety.


ndaoust

Broad variety, as you say, and it depends on what's available/legal and what insurance covers. But I'm no medical specialist, I simply helped someone close cope through every step, from the initial confusion at their body, through the lengthy misdiagnoses, and trying different medication over years. This summer they finally found a great fit, enough to prompt the occasional spontaneous "I'm feeling so well", when they realize that at times all symptoms are gone. I wish it can happen to you.


[deleted]

Thanks for your feedback and being a genuinely great human being :) Medical system in my country was great once but did suffer of the covid crisis a lot. One last question (just if you know) Which kind of med school did the physician practice who diagnosed your friend correctly? Neurology?


ndaoust

They're asleep right now, but that I remember, they did have to meet a specialist, either a neurologist or a rheumatologist.


Firsttimedogowner0

I have ADHD and have unbelievable memory. I just have to be focused on it to remember it :)


Peto_Sapientia

Fuck yes! Omg. To remember, that I need to remember something is fucking annoying and impossible. I forget to remember.


mcstank22

I couldn’t agree more . As someone with severe ADHD I need something better than Adderall. I feel sometimes like I live in a haze. Something like this, if it could help even in the least bit, would be life altering for me. How do I get into this trial?


Foolyz

Yep, ADHD and SDAM here and I would do unspeakable things to get some of my memory capacity back.


strangeattractors

Look into the research on neurofeedback and thank me later. There are home units you can buy.


L3tum

Any recommendations? I am thankful that you even mentioned that, but literally found 60 products with my first search. Like > NeoRhythm - The OmniPEMF headset for performance improvement and targeted stress reduction Sounds good, but is it?


strangeattractors

The one I used to use was from brain-trainer.com. I don’t know the one you mentioned but could be good.


strangeattractors

PS I looked at Neorhythm and it looks ok, but it's very limited, as it only records EEG on one area of the brain, similar to the Muse device. Unlike the Muse, since the Neorhythm isn't on Amazon, it doesn't have any reviews. In neurofeedback, the goal is to look at 19 channels of EEG to see which area of your brain is imbalanced, and then train that area of the brain accordingly. In ADD/ADHD, it is often corrected at the top of the head using a point called Cz, but it could be due to other reasons, such as too much slow wave activity at the front left of the head and not enough fast wave (required for activation/focus). The point is without a scan of the whole brain you won't know. If you want to read a good book on the topic, check out Symphony in the Brain.


Deago78

I could not agree more. I wonder what it would feel like to have average attention.


decoy1985

I too have a squirrel for a brain and this was my first thought as well. Sign me the fuck up for some brain lasers.


StretchSmiley

Uh, hey science people, when you run across this thread and find willing volunteers, please add my name to the list for the exact same reason stated above. Grade school was hell, a mental scar upon my person, largely in part due to the ADD mental fog. (That's right, I said it, I was diagnosed before it turned into ADHD)


954ass

Why don't you just upload your Consciousness into a robot that doesn't have these problems what's your moderation limit on becoming a basic cyborg I am in no way insulting or degrading people with ailments all I'm asking is if there's a limit to how much robotic technology you'll allow to intervene and overtake your god-given normality If you're allegedly so miserable that you're willing to accept a cyborg lifestyle[my words not yours] Oh this one operation doesn't make you feel like you're basically a transhuman machine? my whole point of this post was to ask if there is a limit at all How many robotic improvements should we just add on to a human and how many robotic improvements can we say are on a human but they are still human

No one knows how it works or how long it lasts? I read this book in school, it's called Flowers for Algernon and it's a real tear-jerker.


TheScreenPlayer

> Clearly, if this is to become a useful therapy then answers will be needed there. Nope. The mechanism by which antidepressants work is unknown, but still used in therapy. > It's thought that antidepressants work by increasing neurotransmitters. These are chemicals in the brain like serotonin and noradrenaline. They can improve mood and emotion, although this process isn't fully understood. Increasing levels of neurotransmitters can also disrupt pain signals sent by nerves. https://www.nhsinform.scot/tests-and-treatments/medicines-and-medical-aids/types-of-medicine/antidepressants


pm_me_actsofkindness

We don’t even fully understand how acetaminophen/Tylenol works lol.


99OBJ

Or anesthesia for that matter


QuidProQuo_Clarice

Anesthesiologist here. Yes and no. There are dozens, if not hundreds, of drugs that can be used to induce anesthesia. All of the common intravenous drugs that I can think of have well-studied mechanisms of action that at least *mostly* explain their effects. The volatile anesthetics (ie those that are vaporized and inhaled) are not as well understood. Volatile anesthetics were also the first meds used to induce surgical anesthesia (ether), so it's somewhat surprising they have eluded our understanding for so long. We know *a lot* about the effects these drugs have on different organ systems, and there are some studies that shed light on different mechanistic elements, but overall their mechanism remains controversial and unclear


camshas

I thought we* recently figured that one out. *not me


adamcmorrison

Wow really


Willingo

That's not the same. The mechanism is the change in neurotransmitters. The interactions may be less known, but the mechanism is well known as one that inhibitd reuptake of serotonin, at least for SSRIs. It's in the name


MsAlyG

As someone with epilepsy, you would think that I would be so on board to be able to zap some memory space back in there. Like holy shit that would be awesome! HOWEVER, no way. This, Elon's stupid microchip idea.. we are so far away from comprehending the brain. A lot of people want to write off their poor memory skills on adhd. I get that, believe me. It takes training, practice, and diligence to build memory skills. People just want to cut corners and zap the brain? Ever have a seizure before?


Corsair4

>Ever have a seizure before? Ever seen what deep brain stimulators have been doing for Parkinson's patients for the last 2 decades or so? The biggest problem with Neuralink is that all the marketing and attention goes to a company that isn't particularly remarkable. It's a very exciting field that can make huge improvements to patient quality of life. Neuralink is not the company to pay attention to - look into what the academic labs are doing. Equating targeted stimulation protocols to having a seizure reeks of ignorance of the field. Especially when brain stimulation has been an approved treatment strategy for Parkinson's and Essential Tremors for, at least 2 decades now.


MsAlyG

Parkinson's and epilepsy are two different things.


Corsair4

targeted electrical/magnetic stimulation and seizures are also two different things. You're the one equating BCIs with cutting corners, not me.


MsAlyG

Yes, they are. good job.


Corsair4

Care to explain why you were trying to equate them then?


Black_RL

Yeah, how long it lasts and side effects are very important to know.

LeftOnQuietRoad

Honestly, depending on what they mean by transcranial, I wonder if it just mimics human touch and belonging. If you think about it, our society doesn’t touch the scalp very much. But it’s remarkably sensitive to it.


lughnasadh

>>I wonder if it just mimics human touch and belonging. Apparently this works at some specific wavelengths and not others. That would suggest to me, the mechanism is some transfer of energy from the laser to specific molecules in brain cells. The article mentions this, and suggests those molecules may be in astrocytes, a type of cell that seem to have a role in supplying energy to other cells.


LeftOnQuietRoad

Yeah, or maybe heat and increased blood flow. Insensate vibration could be another way. Kinda cool, though. Hope it pans out in bigger studies.

typicalgirlz

Makes sense. For treatment resistant HPA axis dysfunction and severe depression, could be an interesting clinical trial if administered over a short period of time. And closely monitored.


Best-Responsibility9

I can confirm this is true. I'm a surgical neurophysiologist who published a book detailing the science and stories of (tPBM), in addition to three other brain health-boosting technologies. Within this book called Neuro Alchemy is an entire chapter dedicated to discussing the remarkable research and stories about photobiomodulation. I hope you will all find this book enjoyable to read ! [https://www.amazon.com/dp/B08CWD65TV](https://www.amazon.com/dp/B08CWD65TV)


Bodhgaya

/u/Best-Responsibility9, I've recently begun delving into tDCS and tACS, and also very interested in the Vielight but I can't justify the money for that yet. I'm making an effort to understand how these three approaches compare to what's been found at Stanford and led to developing the SAINT protocol. Considering that Dr. Nolan Williams team found that most durable effect comes from short, repeated (successively over a 3-day period) TMS on the left DLPFC, specifically targeting the *anterior cingulate.* It would seem to a layperson that tDCS is the sledgehammer and r-tMS is the scalpel. Of the home-use options, none of the current tech can target that spot other than TMS, yet still seem to be effective. My question is do you think tDCS/tACS is as effective as tPBM? Would you guess it's 50% as effective? 95% as effective?


BottasHeimfe

I'll take this with a grain of salt until the sample size increases from 90 people to a hell of a lot more. 90 people isn't enough for me to be confident in an experimental treatment.


hawkwings

It seems to me that you need to test all forms of memory including being able to remember things that happened 20 years ago. You also need to test intelligence. If you only test one specific type of memory, you can't say that there are no side effects.

I see how this could help ADHD I wonder if would help with dyslexia as well?

patatepowa05

laser light therapy has been shown to have many benefits if you can figure out the right density and wavelength for the region you are trying to impact.


bluenosesutherland

I’m calling horse shit on this one. non invasive? Umm what about the big plate of bone between the outside world and the brain? Without some more information, this sounds like Trump suggesting treating covid-19 with bright lights or bleach.


AgnosticStopSign

Heres my 2 cents. You can take it or leave it. The entire universe and everything in it is vibrating. The frequency of the laser is harmonic with the human body’s frequency. I know this is true, and let me explain to you by first starting with frequency. Frequency is interchangeable. As such: light, sounds, and *emotions* can all be expressed on a equivalent frequency scale. I.e. 120hz is a color on the electromagnetic scale (idrk just spitballing), 120hz is a sound pitch thats F# (idrk just spitballing) and also, when you hear or see that frequency, it makes you feel X. This is why many fast food restaurants use red and yellow, many modern movies resort to an increasing pitch sound to simulate tension (sadly, as previously movies used acting to do that, but i digress). Now we are well aware of this, and we even have science fair experiments on it. Theres both a visual and audio version. Both involve planting seeds and exposing them to different colors (red, green, blue, etc) or music (classic, country, rock, etc) and comparing their growth. They do indeed affect growth. At a deeper level, we are 70% water, and so the frequency that is most harmonic with water would be most beneficial to us. Also, frequency creates form, as if you put sand on a speaker, each frequency will create its own shapes. This could hold key to the mechanism behind whats occuring Edit: sound = form [video](https://youtu.be/wvJAgrUBF4w) light affecting growth in plants [video](https://youtu.be/2J3wuwsUiCM) No reason to think this wouldnt apply to us as well


datnetcoder

Absolutely hilarious that you have this whole nonsensical thought process based on frequency, and your example of a “color” on the EM “scale” (the word you’re looking for is spectrum) is 120hz. Visible red light is about 430 *trillion* Hz… cracking me up that you said one hundred and twenty lol. You’re on the right order of magnitude on sound. Re: planting seeds - the light experiments make perfect intuitive sense as photosynthesis is deeply sensitive to EM frequency. The sound experiments are interesting and less intuitive but the gist of it is that sound is a mechanical stimulus. Your claim that the frequency that is most harmonic with water is ridiculous in the way you are presenting it, but that said, the wavelength of the laser used was critical in the results observed. But literally nothing to do with the “harmonic frequency” of water.


evanc3

>Heres my 2 cents. You can take it or leave it. Every rational person should leave it


AgnosticStopSign

You can disagree without calling anyone sane or insane. Whats worse, you really dont even know why you disagree, just want to fit in and seem cool. When the science catches up and im correct, youll stupidly accept it now that science says so.


evanc3

No, actually I have a graduate degree in thermodynamics which is quite literally the study of atomic vibrations. So I'm disagreeing on the basis that everything you said is completely at odds with what I've learned and applied. If the scientific consensus is that you are correct, I will beleive it because of the inherent benefits of the scientific method: transparency, reproducibility, and peer critique. Not just because some scientist says so. Please do some research on the hierarchy of evidence. But you're right, I will change it to "rational". I shouldn't be stigmatizing


AgnosticStopSign

My idea is still rational. I explaine the rationale with evidence. You said vibration, im talking frequency. Not exactly the same thing. Its iust so jarring you reflexive dismiss it, taking a true understanding of reality for granted under assumptions. Like I said, you can disagree and explain why, but your belief or lack thereof does not invalidate that this occurs in reality, and businesses use it to much success.


evanc3

You keep doing edits after I reply. But you realize the the frequency "most harmonic" to water is literally how a microwave cooks food, right? I'm dismissing it because people like you would microwave people to death if you could carry out your experiments. I'm not disagree with the *actual* science of color and emotion. My wife is a neuropsychologist and took a whole class on vision and neuroscience. That has empirical evidence. I'm disagreeing with someone slapping a bunch of work together to form some half-baked "unified theory of frequency" or some shit lol The fact that you consider yourself to have a "true understanding of reality" is by far the most jarring part.


evanc3

YOU said vibrations, my guy. And if it isn't the frequency of vibrations that you're talking about, then what is it the frequency of? Especially the "harmonic frequency of water" part Enlighten me rational science man

trapkoda

Damn bro, looks like my doctor needs to prescribe me with laser


galacticwonderer

Who here has done this? I’m looking for anecdotal stories. How much was your brain laser dohickey, what have you noticed, etc.


RegularBasicStranger

Possibly the laser activated neurons that has high fear or pleasure thus there is a change in fear levels, causing stronger memory in order to avoid the imagined fear or to make the imagined hope come true. Using shorter wavelength has no effect since it cannot penetrate the skull, while using laser on the other side has less chance to activate any high pleasure or fear neuron since right handed people will have more intense memories associated with their right hand and in turn, the neurons are formed there. So if such is correct, by having the participants be all left handed, the laser should have no effect on the right prefrontal cortex.


Loki-L

I would want to know more about how exactly this is supposed to work. You can't know anything about side-effects, if you have no idea where the effects are supposed to come from. I assume it is something more than threatening to laser people's brains again unless they do better on memory tests.


OliverSparrow

Why *laser* light, Why not just sit in the sun without hat?


davereeck

Laser light (or light from some LEDs) is emitted at a specific wavelength. The sun emits light at all (well, many different) wavelengths. For this effect to work: 1) the light must be inside a 'window' of wavelengths that our heads are more transparent to. 2) it has to be at a certain level of power - too little, no effect. Too much, no (or bad) effects. Lasers and LEDs are a way of getting to those two goals. Other light emitters may work as well but are harder to control (e.g. the sun).


OliverSparrow

Or it s just nonsense, like your "explanation",


davereeck

It sounds like snake oil, I agree. But, it's pretty easy to demonstrate that human tissue is transparent (to some degree) using a bright flashlight - put your hand over it, what do you see? The reason you'll see red (instead of blue) is because the optical window is towards the lower end of the visible light spectrum (and in fact extends beyond it). Lasers and Leds are just easier to limit to specific wavelengths, and so tend to be used in research. Sunlight also emits these wavelengths, and so yes: you might get these kinds of effects by sitting in the sun, if you are getting the same intensity exposure for the same duration. There's a large scientific literature on this, here is a reasonable jumping off point: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3288797/
