Lithium Reverses Alzheimer's in Mice

Things I love to read.

I went to visit my aunt one day, and my favourite uncle couldn't recognize me. It made me think that Alzheimer's is probably the worst thing that could happen to a person. I mean, what's worse than not being able to recognize those closest to you? You work a lifetime, and then you go out in such an undignified manner.

I pray for a cure in my lifetime.

outworlder•55m ago
It's worse. Not recognizing people close to you is really hard on everyone else(including people taking care of you), but since you don't remember, it's not as bad for you.

You won't even remember whether or not you had lunch. I met a grandma that was distraught that nobody was feeding her and she was hungry. Except she had had lunch already but couldn't remember. You forget where you live so if you get out of the house you can't get back. And many have 'sundowning', they get scared if they are outside and the night falls. It's not just the forgetting either, you start losing fundamental functions and eventually die. Not to mention the aggression and mood swings, which are aggravated if you try to point out that they are forgetting things.

It's a terrible disease. You cease to be you.

cubefox•43m ago
> It made me think that Alzheimer's is probably the worst thing that could happen to a person.

Alzheimer's is slowly destroying the person, but this might in some cases be not as bad as diseases which leave the person in place but make them suffer intensely, e.g. from pain or depression. Though it's hard to compare.

switchbak•18m ago
> It made me think that Alzheimer's is probably the worst thing that could happen to a person

I've had relatives die of Alzheimer's, and others die from other causes. Let me assure you that there are worse fates than the one you describe.

Lithium orotate is available over the counter. People could try it today.

> Since lithium has not yet been shown to be safe or effective in protecting against neurodegeneration in humans, Yankner emphasizes that people should not take lithium compounds on their own

I reject this kind of blind safetyism. A cursory search suggests that lithium orotate has been used for decades, and the article suggests that "profound effects" were seen at an "exquisitely low dose" which should be safe. They're going to need a much better explanation of why people shouldn't try it.

adamgordonbell•54m ago
People use it in much smaller dosages then it's usually prescribed to apparently beneficial effect.

I believe its also in the water supply in certain places, so if it works for dementia there are natural experiments already running on this.

cypherpunks01•46m ago
Yes, it's already thought that there's an association between naturally occurring lithium in drinking water and decreased suicide rates:

https://www.cambridge.org/core/journals/the-british-journal-...

I would think naturally occurring lithium in some people's water would give pretty good control conditions to do a wide study of this effect on Alzheimers as well?

Mistletoe•44m ago
This is fascinating, thank you.
valianteffort•2m ago
The addition of flouride to tap water supply likely affects brain development. Let's not go adding lithium too.

These things are simple enough to advise the populace to use on their own. The government should never play nanny, ever.

cubefox•48m ago
> They're going to need a much better explanation of why people shouldn't try it.

Clinical trials need many participants and take a long time, and they require a control group which doesn't take lithium orotate. Finding these people might be hard if everyone is taking it anyway.

wonderwonder•40m ago
So if after a long time its proven that it does prevent Alzheimer's, was the deaths of everyone that would have been taking lithium to prevent it due to this anecdotal article worth it?

Would you be willing to die of Alzheimer's in order to serve as a placebo for the control group? What about your parents?

I don't really understand this mindset.

I already ordered 5mg tablets of lithium orate as soon as I read this. I'll just add them to the handfuls of other supplements I take each day just in case they may protect against common degenerative ailments.

I very much adhere to the better safe than sorry or yolo approach to supplementation.

Angostura•33m ago
> I don't really understand this mindset.

It's called evidence-based medicine and it's useful for answering questions such such as 'with taking Lithium prevent Alzheimer's by ensuring you die of kidney disease first.

Taking a bunch of unnecessary supplements isn't inherently "safe".

wonderwonder•18m ago
Low dose lithium is not going to cause kidney failure. I was also responding specifically to OP advocating for people to intentionally not to take it so there is a ready supply of people to test it on who are not already on it for a long period of time (decades). They are advocating for self sacrifice.

This by default means there must be a large supply of people not on it for a long period of time who will suffer and die from Alzheimer's instead of just taking the supplement. That was my issue. It seemed to call for the self sacrifice of many in order to allow for a long term study. But I think you already know that if you read my response and just chose to focus on a single sentence.

cubefox•13m ago
The alternative to a clinical trial would be that there continues to be much less certainty whether lithium orotate actually works and is safe. Which would result in less or more usage than optimal.
wonderwonder•10m ago
I will ask you the same question I asked OP

"Would you be willing to die of Alzheimer's in order to serve as a placebo for the control group? What about your parents?"

Since that is essentially what you are asking the people that would have ordered low dose lithium based on this article to do.

jsbisviewtiful•47m ago
> I reject this kind of blind safetyism.

You said you searched to learn more about lithium, but somehow missed that it's highly recommended to be administered by doctors due to side effects after long term use. Anything that damages your kidneys or thyroids can kill you, so calling it "blind safetyism" is silly.

rogerrogerr•33m ago
It’s blind safetyism when an article writes “don’t do this because no one has proven it is safe”. Most people will read that as “you can probably do this but in the off chance something bad happens, I wrote these words so you have a harder time suing me”.

It would be more useful and effective for the article to say “don’t do this to yourself because it can damage your guts, see these links, there’s tradeoffs here”

The former just fades into the modern world’s background noise of unchecked ass-covering.

CoastalCoder•29m ago
> The former just fades into the modern world’s background noise of unchecked ass-covering.

The missing piece of this argument is just what the probability of different legal risks is here.

Wether or not their ass-covering is reasonable hinges on that and on their risk tolerance.

rogerrogerr•23m ago
Oh, it’s rational for them! That’s the problem - it’s always rational to treat anything you write as the highest level of liability. No one looses money for adding more disclaimers. Observe:

Drinking water is a good idea.

*check with your doctor if you are allergic to water, have a history of drowning, or are unable to distinguish water from ethanol. Do not consume water while intubated. People with rabies may have adverse reactions to water. Use caution when drinking water if you cannot swallow or are currently vomiting. Water from some sources may be contaminated. Salt water may contain jellyfish.

—-

My legal exposure from the initial statement went down with every little stupid disclaimer I added there, and there’s no penalty for each one. But you probably didn’t even read the full thing. We’ve created a culture of everyone feeling like they need to cover their ass, and the real important things get drowned out.

tgv•26m ago
Especially since mice are not really perfect models for humans. For starters: these mice were "12 to 24 months of age", whereas your typical Alzheimer patient is well over 30 times that. The article also links it to amyloid plaques, which is a contested hypothesis that may well have held back Alzheimer research for decades. To be fair, the article seems to look at more mechanisms, but that's well beyond my expertise.
hollerith•24m ago
The kidney damage, etc, are consequences of the very high doses of lithium needed to control bipolar disorder.

Most experts who have been recommending lithium supplementation to support general health recommend doses about 100 or 500 times lower.

wonderwonder•35m ago
I ordered 5mg tablets of Lithium Orate 5 minutes after reading this article on X. I take EGCG as well due to a similar article.
alphazard•29m ago
The error in "safteyism" isn't that the conventional wisdom will incorrectly identify safe things as dangerous. It's that risk and reward always exists on a spectrum, and the people best incentivized to get that tradeoff right are patients and caretakers, not concerned 3rd parties.

The error of the concerned 3rd party is particularly egregious with a disease like Alzheimer's, which presents a significant risk of ruin in the form of information death. It is totally rational to use an intervention that will cause you significant harm if it preserves your mind another few years.

lawlessone•20m ago
I've heard of suggestions that it should be added to water(in low doses of course) to see it reduces suicide rates.

I like the idea but can only imagine the anti-flouride crowd would freak out.

Lithium-6 if I recall correctly was the preferred isotope (for the brain, not this study). I don't recall why.

Lithium is a strange drug. It also cures bipolar disorder and nobody knows why. It also fucks up the liver over time and basically people on lithium eventually have to make a choice between dying or being insane.
bink•47m ago
Surely the minimal dosage they're studying here won't have such dramatic impacts on the liver? It's basically what's available in some water sources. It's also available in food sources like leafy greens, nuts, and legumes.
exmadscientist•38m ago
It's mostly the kidneys that get damaged, not so much the liver. It also has a massive amount of benign or merely annoying side effects. Lithium might even be the drug with the largest overall amount of side effects. It's certainly a weird one.

High-dose lithium is extremely hard on your kidneys and may well lead to kidney failure in a decade or so. Medium-dose lithium is a lot more gentle but still requires monitoring. Many people can go down in dose after initial treatment, and good psych prescribers will attempt to do this after a while. (Or patients will request it, after the other side effects of lithium become noticable after the bipolar has settled down.) Low-dose lithium is much harder to study and may well be pretty safe. May.

It is not quite true that people have no idea how it cures bipolar disorder. It's definitely affecting the ion channels (sodium, potassium, etc), just like many other anticonvulsant drugs also used for treating bipolar. So the mechanism for action is not totally insane and unique. Now, why the ion channels are the place to go for certain people, that's an open question....

hirvi74•22m ago
That's quite a stretch. Lithium does not cure bipolar disorder nor is it effective in many afflicted. Also, Lithium is not the only medication for Bipolar Disorder, there are a double-digit number of alternative options.

Also, to my knowledge, we are not entirely sure why most, if not all, of the psychiatric drugs work. Plenty of hypotheses though.
