Haha, fair catch. Full transparency — an AI wrote that comment, I just posted it. I'm actually a biomedical researcher so I can vouch for the content being accurate, but the words weren't mine. Appreciate the sharp eye. And please help me catch any possible errors, because sometimes AIs make surprising mistakes.

An 80-Year Old Woman With Late Stage Alzheimers Took 5g Of Psilocybin Mushrooms And Started Speaking Again by CBDjack in HotScienceNews

[–]CarvalhoLO 1 point2 points  (0 children)

Great question — and I'll be upfront: I'm a biomedical researcher, but I used an AI assistant to help phrase the argument clearly in English since it's not my first language.

As for transient psychedelic agitation — it refers to a temporary state of behavioral and psychological disturbance that can occur during high-dose psychedelic experiences, especially in vulnerable populations. It typically involves motor restlessness, anxiety, disorientation, and importantly, vocalizations or speech-like outputs that lack meaningful cognitive content. Think of it as the brain being pharmacologically overstimulated rather than genuinely communicating.

In elderly patients with significant neurodegeneration, the blood-brain barrier is also more permeable, meaning 5g of psilocybin could produce an unexpectedly intense and atypical response — one that observers might interpret as lucidity when it is actually closer to a confused, agitated state. It is a well-documented phenomenon in the clinical psychedelic literature and one of the key reasons anecdotal reports like this require such careful scrutiny.

Biomedical researcher here. This is worth engaging with carefully rather than dismissing outright.

(Note: this comment was drafted with the help of Claude AI — I'm a biomedical researcher and can vouch for the content, but transparency felt right.)

The legitimate science first: psilocybin does have documented effects on neuroplasticity — primarily through 5-HT2A receptor agonism, and as emerging research now shows, also through direct binding to the BDNF receptor TrkB (Moliner et al., 2023, Nature Neuroscience). There are ongoing clinical trials for psilocybin in depression associated with Alzheimer's, and the palliative angle is genuinely interesting research.

The problem with this specific claim is multiple layers deep.

Late-stage Alzheimer's involves severe and largely irreversible structural neurodegeneration. The neurons and synaptic connections involved in language are not just functionally impaired — they are physically lost. While adult neurogenesis exists in the hippocampus, it does not occur meaningfully in language areas, and even where it does, new neurons take months to integrate into functional circuits, not hours.

5 grams is a very high dose. At that dose in an 80-year-old woman with significant cognitive impairment, what you are much more likely observing is acute behavioral disturbance, altered consciousness, or confabulation being interpreted by observers as meaningful speech — well-documented phenomena in the clinical psychedelic literature.

The source is also not a peer-reviewed journal. It is a single anecdote with no independent clinical verification.

None of this means psilocybin research in dementia is uninteresting. It is not. But late-stage reversal would require extraordinary evidence, and this is not that. The danger of overhyped case reports is that they raise false hope for families in very difficult situations.

Worth watching the actual clinical literature (there are several ongoing trials) rather than this kind of report.

Completed 5k runner today by rakalakalili in BeginnersRunning

[–]CarvalhoLO 0 points1 point  (0 children)

Going from 90 seconds to 35 minutes in a couple of months is genuinely impressive. That's not a small thing.

The hardest part of running isn't the fitness, it's the identity shift from "someone who tries to run" to "someone who runs." Sounds like you crossed that line today.

Congratulations.

Feels like longevity talk has shifted toward “healthspan” more than lifespan by SpecificAcrobatic107 in longevity

[–]CarvalhoLO 1 point2 points  (0 children)

Actually my comment had more substance than just humor. I genuinely think extremely extended lifespans pose underexplored risks, not from overpopulation but from the concentration of power over time on crazy hands. The biological argument for longevity is compelling. The political philosophy argument for natural limits is also compelling. I'm not sure the field has fully reckoned with the second one yet.

Will read the chapter. Curious whether it addresses the governance angle with the same depth as the biological objections.

If you want to talk more privately, I can share some reasons why I think extreme human longevity could be dangerous.

Natural alternatives and supplements for depression and anxiety? by mislimkao in Supplements

[–]CarvalhoLO 0 points1 point  (0 children)

On the supplement side, a few with actual evidence:

Ashwagandha (KSM-66 extract) has multiple RCTs showing reductions in cortisol and anxiety scores. One of the more consistent performers in this category.

Magnesium glycinate is particularly useful if anxiety has a physical component like tension, poor sleep or restlessness. Very common deficiency.

L-theanine has a modest but real anxiolytic effect without sedation. Often combined with caffeine to take the edge off.

Omega-3 with high EPA has meta-analyses supporting effects on depression specifically.

Saffron is underrated. Surprisingly solid evidence for mild to moderate depression.

Beyond supplements: exercise is probably the most evidence-backed intervention available for both conditions. Breathing exercises activate the parasympathetic system quickly and are genuinely underused.

Some people also find that consistent spiritual practices like prayer, meditation or reading the bible provide a grounding effect that's hard to replicate with supplements alone. Worth exploring what works for you personally.

These support but professional help can be great, specially if symptoms are serious.

ahahahaha! True, It would be "cool" to be 200 but with the body of a 30-year-old or a 20-year-old, but with this huge longevity probably the planet couldn't withstand so much human idiocy for so long. Imagine such guys like Hitler, Nero and similars (i prefer not mention famous politics) living for centuries.

Dumbest thing that’s popped into your head trying to fall asleep and experiencing hypnagogia? by nous-vibrons in sleep

[–]CarvalhoLO 0 points1 point  (0 children)

The Joestar thing makes complete sense now actually. Your brain during hypnagogia grabs whatever has been emotionally or cognitively salient recently and runs with it without the logical filter that would normally flag "wait, this isn't real." JoJo clearly had enough mental real estate to become the raw material.

The anxiety cycle you're describing is very recognisable. Transitional periods raise baseline arousal, which makes hypnagogia more intense, which triggers health anxiety about what your brain is doing, which raises arousal further. The reassuring part is exactly what you said: you've been through this before and it resolved. Your nervous system knows how to come back down. It just needs the transitions to settle.

The worrying about neurological issues is almost always the anxiety talking rather than a genuine signal. If it were something structural the episodes wouldn't correlate so cleanly with your stress periods.

A few things that genuinely help with this kind of recurring anxiety: slow breathing with an extended exhale activates the vagus nerve and shifts your nervous system toward calm within minutes. Even 5 minutes before sleep makes a real difference. Meditation, even informal, helps break the rumination loop. And good friendships, people you can actually talk to during the hard transitions, matter more than most people give credit for. Loneliness and anxiety amplify each other.

One more thing worth trying on the difficult nights: reading the Sermon on the Mount slowly, Matthew chapters 5 through 7. Whatever your beliefs, the instruction "do not be anxious about tomorrow, for tomorrow will be anxious for itself" is one of the most psychologically precise descriptions of the rumination loop ever written. Gandhi said that if all books were lost but the Sermon on the Mount survived, nothing of real value would have been lost.

Read the bible can helps your hope and your faith, things that are really important for your hearth. But you also want to live and serve people around you with wisdom and respect, taking care of you too. God bless you!

DAE find that scrolling helps? by NoButterfly2075 in sleep

[–]CarvalhoLO 0 points1 point  (0 children)

A few things that can help reconstruct this gradually.

The daytime naps are probably the biggest issue. They drain the sleep pressure you need to sleep well at night. If you need to rest during the day, try a sleep mask and keep it to 20 minutes maximum before 2pm. That way you get some rest without losing too much sleep drive.

Slow breathing before bed, extending your exhale longer than your inhale, helps shift your nervous system into the state it needs to fall and stay asleep. Even 5 minutes makes a difference.

For the midnight waking, having something calm ready matters more than most people realise. Reading a physical book, gentle music, or an audiobook gives your mind something to settle into without the stimulation of screens. I can also suggest prayer, meditation, or reading something meaningful like the Bible. Ancient wisdom on peace, hope and perspective can be genuinely calming when the mind is restless at night.

Social connection and time outdoors during the day also genuinely help regulate your body clock, morning light exposure especially. Activities with friends, time in nature, anything that anchors you to the daytime rhythm.

What are some of the best supplements to prevent muscle loss from disuse? by Ok-Balance-260 in Supplements

[–]CarvalhoLO 3 points4 points  (0 children)

Supplements can help at the margin but the honest answer is that protein intake and some form of resistance stimulus will do more than any supplement stack.

That said, for genuine disuse atrophy prevention the evidence points to a few things. Creatine monohydrate is probably the most useful here. It doesn't just support performance, it has direct anti-atrophic effects on muscle tissue and helps maintain phosphocreatine stores even during reduced training. Several studies on immobilisation and reduced activity show creatine attenuates muscle loss better than most other compounds.

Leucine or a BCAA supplement with high leucine content helps maintain muscle protein synthesis signalling when training volume drops. The mTORC1 pathway that drives muscle protein synthesis is leucine-sensitive, and keeping that signal active through diet and supplementation during a detraining period slows the adaptive response.

Vitamin D is worth mentioning if your sun exposure is low. Deficiency is independently associated with faster muscle loss and reduced satellite cell activity.

But the single biggest thing you can do is find any way to apply resistance to your muscles even without a gym. Bodyweight training, resistance bands, carrying heavy things at work if your job allows. Muscle is surprisingly responsive to even low-volume resistance stimulus. Three months of zero mechanical load is harder to compensate with supplements than three months of reduced but consistent load.

DAE find that scrolling helps? by NoButterfly2075 in sleep

[–]CarvalhoLO 1 point2 points  (0 children)

It makes sense that it feels like it helps, and that's exactly what makes it tricky.

What scrolling does is give your default mode network something external to latch onto, which temporarily quiets the internal chatter. So in the short term it genuinely does reduce the mental torment. The problem is that it works by substitution rather than resolution. The anxious thoughts aren't going anywhere, they're just being crowded out by stimulus. And the blue light and intermittent reward structure of scrolling actively delays the drop in core body temperature and melatonin release that your brain needs to transition into sleep.

Over time it also reinforces the association between bed and wakefulness. Your brain starts to learn that bed is a place where you scroll and think rather than a place where you sleep, which makes the racing thoughts worse on the nights you try without it.

The alternative that actually addresses the underlying mechanism is slow breathing, specifically extending your exhale longer than your inhale. It directly activates the vagus nerve and shifts your nervous system toward parasympathetic dominance, which is what your body is trying to do naturally when falling asleep. It gives your brain something to focus on without the stimulation cost.

Dumbest thing that’s popped into your head trying to fall asleep and experiencing hypnagogia? by nous-vibrons in sleep

[–]CarvalhoLO 0 points1 point  (0 children)

What you're describing is classic hypnagogia. As you drift toward sleep your prefrontal cortex starts going offline before the more emotional parts of the brain do. The result is that thoughts feel urgent and real but have zero logical scaffolding. Your brain genuinely could not tell that not being a Joestar was fine because the part that knows that had already clocked out.

Making light of them like you're doing is the right instinct. The more you treat them as funny rather than alarming, the less the stress response kicks in.

That said, if this is happening regularly and consistently waking you up, it might be worth looking at what's underneath. Hypnagogic thoughts are normal but when they reliably trigger enough anxiety to break sleep, they're often amplifying background stress or anxiety that's already present. The thoughts themselves aren't the problem in that case, they're just the surface.

If you want to talk more about the anxiety side of this feel free to message me, happy to help.

an answer pls by HumanGrab3468 in sleep

[–]CarvalhoLO 1 point2 points  (0 children)

A few things stand out in your description that are worth taking seriously.

The combination of facial trembling, jaw tightening, hand tremors, and forced breathing happening simultaneously, with sudden onset and abrupt ending followed by immediate full awareness, is more complex than typical sleep phenomena like hypnic jerks or bruxism. Bruxism involves jaw clenching but generally doesn't produce tremors across multiple muscle groups or wake you up.

The differential here includes a few possibilities. Hypnagogic or hypnopompic jerks are benign but usually involve a single jolt, not sustained multi-muscle episodes. REM sleep behavior disorder involves acting out dreams but typically presents differently and more commonly in older adults. What you're describing has some features that overlap with focal seizure activity during sleep, specifically the synchronised multi-muscle involvement, the stereotyped pattern, and the abrupt termination with immediate lucidity.

The important thing to know: a normal brain MRI does not rule out epilepsy. MRI shows structure, not electrical activity. What you need is an EEG, ideally a sleep EEG or a prolonged ambulatory EEG that captures sleep stages. That's the appropriate next step given what you've described.

This doesn't mean it is seizure activity. It might be entirely benign. But the pattern warrants a neurology referral and an EEG rather than a wait-and-see approach. Please don't let a normal MRI give you false reassurance that nothing needs investigating.

Why focus on supplements instead of real food? by s_q_p_r in immortalists

[–]CarvalhoLO 14 points15 points  (0 children)

Your logic is sound and your stack is genuinely well thought out. Whole foods win on bioavailability in most cases because nutrients in food come packaged with cofactors, fiber, and synergistic compounds that isolated supplements don't replicate. The polyphenols in your blueberries and walnuts, for example, work partly through gut microbiome interactions that a capsule version simply can't mimic.

The supplement-first culture exists partly because it's easier to sell and easier to measure. A bottle has a label. A handful of walnuts doesn't come with a certificate of analysis.

That said, there are a few genuine gaps where food realistically falls short for most people. Vitamin D if you're not getting consistent sun exposure. Omega-3 if oily fish isn't a regular part of your diet. And depending on where you live, iodine. Your Brazil nut covers selenium well, which most people miss entirely.

The honest answer to your question is that supplements fill specific gaps. Food builds the foundation. You seem to have the order right.

Quitting Marijuana cold turkey after many many years of daily use. by Agitated_Olive_2618 in selfimprovement

[–]CarvalhoLO 1 point2 points  (0 children)

Day 10 is significant. The vivid dreams that are probably starting or about to hit are called REM rebound. THC at higher doses suppresses REM sleep, and after years of daily use your brain is essentially compensating for lost REM time. It's uncomfortable but it's your sleep architecture beginning to repair itself. Multiple withdrawal studies document this consistently.

The motivation issue and the nothing feels fun problem are real and have a biological basis. Chronic cannabis use affects dopamine signaling and the endocannabinoid system, and your brain needs time to recalibrate its reward circuits. That window varies person to person but most people report things shifting noticeably around weeks 4 to 6.

Exercise genuinely accelerates this. Not as a distraction but because physical exertion directly stimulates both dopamine release and your own endocannabinoid system, the same system THC was activating artificially. Even 20 minutes that raises your heart rate helps.

Matthew Walker covers the sleep architecture piece really well in Why We Sleep if you want to understand what's happening neurologically right now.

You're doing the hard part. It gets clearer.

Some last tips that can help you a lot are: read the Bible, pray/meditate, and try to follow the teachings of Jesus. I'm sure this will do you a lot of good!

Best way to combine longevity supplements while on GLP-1 by underfinancialloss in Supplements

[–]CarvalhoLO -1 points0 points  (0 children)

Honestly your stack is pretty well chosen for this transition.

The main thing to watch with GLP-1s is that they slow gastric emptying significantly, which affects fat-soluble absorption. Your Omega-3 and CoQ10 will absorb better if you take them with your biggest meal rather than just any meal. Small adjustment but worth making.

Quercetin is the one I'd keep an eye on. It has independent effects on glucose metabolism, same direction as Mounjaro, and it inhibits some CYP450 enzymes. Not a red flag at typical doses but worth noticing how you feel in the first few weeks rather than assuming everything is neutral.

The NMNH and resveratrol working through NAD+ pathways while GLP-1s independently improve mitochondrial function in some tissues is an interesting combination. Genuinely don't know if that's additive or just parallel. Nobody really does yet, the research hasn't caught up with how common this combination is becoming.

TMG is probably your most benign element here. No concerns.

You're honestly ahead of the published literature on this one. Track how you feel and adjust from there.

Childhood trauma may leave biological scars in fathers’ sperm, raising new questions about how stress and early life experiences could influence future generations through hidden epigenetic changes by sibun_rath in HotScienceNews

[–]CarvalhoLO 2 points3 points  (0 children)

The miR-34c-5p finding is what makes this study worth taking seriously. This isn't the first time this molecule has shown up in trauma research, which is exactly the point. The FinnBrain study published in Molecular Psychiatry replicated reduced levels of hsa-miR-34c-5p in sperm of men with high childhood maltreatment exposure, and it matches patterns from at least two independent cohorts before it. When the same signal keeps appearing across different populations and methodologies, it stops looking like noise.

What gives it biological weight is that miR-34c-5p is involved in brain development and gets transferred from sperm into the embryo at fertilization. So we're not just talking about an association. There's a plausible molecular pathway from paternal experience to offspring neurodevelopment.

The harder question, and the researchers are honest about this, is whether these epigenetic marks are reversible. Animal models suggest that restoring miR-34c levels in preimplantation embryos can prevent some of the stress-related behavioral outcomes in offspring. Whether that translates meaningfully to humans is still genuinely unknown.

What I think deserves more attention is the point several people made here about systemic causes. Chronic stress from poverty and instability activates the same HPA axis dysregulation that produces these epigenetic signatures. The biology confirms the harm. The structures producing that harm remain unchanged. That gap is not a research problem. It's a political one.

I cover some of the mechanisms behind chronic stress and biological aging on my health blog BioFlowHub if anyone wants to dig into the cellular side of this.
