    If you've read Ted Chiang's "Understand," you'll understand why this headline made my eyes pop out. For those who haven't, it's in the "Stories of Your Life and Others" collection, which includes the short story that the film Arrival was based on.

      I just read this a few months ago and it was my first thought as well! Like Flowers for Algernon taken to its extremes.

    Wonder what criteria they're using to define "first" here, as I'm aware Clinuvels afamelanotide treatment had positive results (though they're not proceeding with it currently as the burdensome regulatory processes make it too risky to have too many pots on the boil) https://biotechdispatch.com.au/news/clinuvel-announces-posit...

      It really depends on how much the company wants to invest. If it really worked, then it would be relatively straightforward for them to put together a Phase II. Not cheap, but relatively straightforward. Or at least it would have been when we had a functioning FDA

      Also, the other definition in question is what the UCLA PR person means by "repairing brain damage". As far as I can tell from the paper - the "drug" part was using some neurotransmitter blockers on brain cells on a Petri dish to see if they could change gene expression or oscillatory firing patterns matching recordings in mice undergoing "physical therapy". They did not actually test to see if the stuff grew new brain cells or dendritic connections.

    How do they test this on mice? Do they trigger brain seizures in them?

    Potentially life changing for male mice...

      People go on about this too much. Its the first step, it shows promise.

      Does that mean it will neccesarily work? No, of course not. But its still exciting to see progress being made.

      You’re right.

      Let’s just skip straight to human trials.

      very happy for those mice

    ... in male mice.

    I think savvy universities want savvy PIs are savvy enough to realize that the point of these is to boost measurable visibility like citation count and h-index, so the headline of a news release boosting the article doesn't matter. They can always blame a copy editor for the headlines. It could read "world peace solved with moon juice." The provost would only care if it generated negative feedback. So it's the PR department's job to juice it as much as possible without getting blowback.

      Isn’t that where all drugs start out? But yea the headline doesnt tell the full story

    > “The goal is to have a medicine that stroke patients can take that produces the effects of rehabilitation,” said Dr. S. Thomas Carmichael, the study’s lead author and professor and chair of UCLA Neurology. “Rehabilitation after stroke is limited in its actual effects because most patients cannot sustain the rehab intensity needed for stroke recovery.

    Sounds truly amazing, I have known two people who had severe strokes - one's PT was contingent on triaging resources to whoever was likely to recover more, another simply hated PT and speech therapy and often refused to participate or do the exercises. Even if it didn't help recovery a medicine like this would have reduced the stress of everyone involved.

    Are there any supplements that can work for neurogenesis? I've heard Lions Mane extract can do this, but I'm not sure. Anybody know of anything?

      If you don't sleep 8+ hours a day every single day, exercise regularly, live in a place with clean air, eat clean food, don't drink alcohol, etc. you're losing your time, no amount of supplement will make up for our modern way of life, you're going to optimise the 0.1% while missing the 99.9% that matters

        That is true, but keep in mind that routine is very difficult to do for someone that makes their living running the rat race, with stress, no time, responsibilities, worry, untreated health problems, etc. If you have the money, job security, then you'll have peace of mind. That will then allow one to live that kind of optimized lifestyle.

          This is why we cannot abide scabs.

      Alpha-GPC and Uridine Monophosphate appear to have some effect, though minor. Also not exactly neurogenesis, but adjacent stuff. Evidence is complicated, there seems to be a signal but it's a weak effect.

      There's (minimal) research on psilocybin doing just that. One of the tragedies of prohibition is that we just weren't able to study these psychedelic compounds easily for 50+ years.

    • dirtbagskier 2 hours ago

      Cardiovascular exercise and strength training. Both are thought to contribute to neurogenesis, even in healthy people

      Nicotine is the only psychoactive substance proven to increase intellectual function. Rote neurogenisis does not - much in the same way height isn’t a proxy for IQ. Stimulants like Adderall, Caffiene, etc are Dunning-Kruger by proxy.

      Of note, cautionary tale is too much neurogenesis is brain cancer...

      • dymk 41 minutes ago

        No, brain cancer is brain cancer.
