BREAKING 🧵

A gut bacterium is showing up — or rather disappearing — across all three phases of COVID-19.

Severely ill patients have less of it.
Recovered patients get it back.
Long COVID patients don't.

Its name is Faecalibacterium prausnitzii. And what it does explains a lot. 👇 F. prausnitzii is one of the most abundant bacteria in a healthy human gut.

It produces butyrate — a molecule that:

• Fuels your colon lining
• Seals your gut barrier
• Suppresses inflammatory signals
• Regulates your immune system

When it disappears, all of that fails at once.

What do people who live past 100 have in common?

Researchers studied 1,575 individuals aged 20 to 117 — including 297 centenarians.

Their guts looked younger than their age. And certain bacteria tell the story.

F. prausnitzii is part of it. Here's what the science shows. 👇

#Longevity #Aging #Microbiome F. prausnitzii declines with normal aging — independent of disease.

In older adults, this depletion contributes to 'inflammaging' — the chronic low-grade inflammation that accelerates biological aging and raises the risk of neurodegeneration, metabolic disease, and immune dysfunction.

Butyrate loss is central.
Less F. prausnitzii means less butyrate means more gut permeability means more systemic inflammation.

Yesterday: Faecalibacterium prausnitzii depleted in Parkinson's disease.

Today: the same bacterium, a different brain disease ... Alzheimer's.

In Alzheimer's, its depletion triggers a completely different chain — one that targets the blood-brain barrier and drives neuroinflammation from the inside.

Here's the science 👇

#Alzheimers #GutBrainAxis F. prausnitzii has been identified as depleted in Alzheimer's patients across multiple human cohort studies.

Ueda et al. 2021 (Cell Reports Medicine) identified specific F. prausnitzii strains as candidate targets for gut microbiome-based intervention in Alzheimer's-type dementia.

Depletion correlates with worse MMSE cognitive scores — the standard clinical test for dementia severity.

🚨 BREAKING
A new drug just hit Phase 3 trials with weight loss numbers that rival bariatric SURGERY.

28.7% of body weight gone.
~71 lbs average.
In 68 weeks.

No scalpel. Once-a-week injection.
It's called Retatrutide — the triple agonist changing obesity treatment.

Let’s explore the good and the bad about it.
Thread 🧵👇 What makes Retatrutide different from Ozempic or Mounjaro?

It hits THREE hormone receptors at once:
→ GLP-1: Kills appetite, slows digestion
→ GIP: Boosts insulin, improves fat metabolism
→ Glucagon: Burns MORE energy, melts liver fat

Ozempic hits 1.
Mounjaro hits 2.
This hits all 3.

That 3rd pathway is the game changer. 👇

BREAKING 🧵
A major network meta-analysis (550 Parkinson’s patients + 456 controls) ...
Found that one gut bacterium is consistently missing in PD.
And lower levels correlate with worse balance and walking problems.

That bacterium is Faecalibacterium prausnitzii.

Here's what the science says 👇

#Parkinsons #GutBrainAxis F. prausnitzii is one of the most abundant bacteria in a healthy gut, making up to 5% of your total microbiome.

It’s a butyrate producer (a key short-chain fatty acid).

Think of it as your gut’s natural anti-inflammatory firefighter.

It feeds colon cells, reduces inflammation, and sends signals to the brain.

Parkinson’s isn’t one disease anymore.

Meet Henry, 64 — newly diagnosed.

His neurologist used skin biopsy, gut markers, and inflammation testing to map his specific drivers.

Now they’re building a precision plan using today’s tools + tomorrow’s clinical trials: replace lost neurons, repair the gut, calm inflammation, and monitor closely.

This is what the future of Parkinson’s care is starting to look like.

Thread 🧠👇 Meet Henry, 64 — just diagnosed after months of a tremor in his right hand.

His neurologist didn’t stop at the clinical exam.

She ordered a skin biopsy for misfolded alpha-synuclein (positive) + a DaTscan.
It came back positive. Diagnosis confirmed.

This matters: up to 25% of Parkinson’s diagnoses based on symptoms alone are wrong.

Confirm the pathology first. These tests are available now.

Don’t skip this step.

BREAKING: A blood-based protein test can reveal how fast your brain's support cells are aging.

If they’re aging too fast, your Alzheimer’s risk jumps 12.59x.
60,542 people.
7,000+ proteins.
40+ cell types.

This is one of the biggest aging papers of 2026.
Here's what it means for your brain. 🧠👇 Your body doesn't age as one unit.

Your liver cells, immune cells, neurons, gut cells — they all have their own biological clocks.

And they don't tick at the same speed.

This study used 7,000 proteins in blood to build aging clocks for 40+ different cell types.

20–25% of people showed accelerated aging in at least one cell type.
1–3% were aging fast in 10 or more cell types simultaneously.

Your chronological age? It barely predicts disease.
Your cellular age? That's a different story.

BREAKING:
Researchers are shining near-infrared light through people's skulls — and it's showing real signals in Alzheimer's brain scans.
Not a gadget.
Not wellness.

Peer-reviewed trials at NYU, Harvard, and a major French multicenter study are now enrolling.

Here's what science actually says — and what it doesn't. 🧵 Photobiomodulation (PBM) = non-thermal red to near-infrared light (typically 600–1100 nm) delivered via LED or laser devices.
It's not heat.
It's not UV.
It's invisible light at specific wavelengths that penetrates tissue.

The key finding: near-infrared light is absorbed by a mitochondrial enzyme called cytochrome c oxidase — the same enzyme that is measurably reduced in Alzheimer's brain tissue.
That overlap is why neuroscientists are paying attention.

BREAKING: 19 hours after a single high-dose psilocybin session, an 80-year-old woman with advanced Alzheimer’s who hadn’t spoken fluidly in 5 years started talking about her life for 4 straight hours.

She hadn't spoken a fluid sentence in 5 years.
This just-published case report is extraordinary — and heavily caveated.

Here's what actually happened. Hype vs the real science.🧵
#Alzheimers #Neuroscience #Psilocybin #Neuroplasticity Here's the full picture:
• 10-year Alzheimer's history. 5 years of near-silence.
• Given 5g of high-potency "Enigma" strain psilocybin mushrooms under supervision in Brazil.
• Acute phase: suspected hyperthermia, profuse sweating, 19-hour sleep-like state.
• Then: spontaneous speech. Autobiographical memories. Four hours of conversation.
• Over the following weeks, bladder continence returned (lost for 5 years), she dressed herself, smiled, and made jokes.
• Second session one month later: recalled family by name, described surfing with her son.

🔴Promising new data:
Red light therapy is showing real results in Parkinson's disease clinical trials —
gait improves, tremors ease, and new brain imaging suggests it may actually protect dopamine neurons.

This isn't fringe science.
It's peer-reviewed.

Here's what the data shows 🧵👇
#Parkinsons #NeurologyResearch First:
What is photobiomodulation (PBM)?
It's red + near-infrared light (600–1000nm) from LEDs or lasers aimed at your cells — no heat, no drugs.
The target? Mitochondria.

The energy factories inside your neurons.

In Parkinson's, those energy factories are failing.
PBM may restart them. 🔬

BREAKING:
Scientists just ran the first-ever clinical trial of creatine in Alzheimer’s patients.
Brain creatine went up.
Memory and thinking improved.

But the same supplement FAILED a 5-year, 1,741-patient Parkinson’s trial in 2015.
What changed?
What does this mean for brain energy?
A thread on the most fascinating story in brain energy research right now. 🧵🧪

#Alzheimers #Parkinsons #Creatine First: why does creatine even make sense for the brain?

Your brain is an energy hog. Your neurons are always energy-hungry.
They run on ATP.
Creatine = your brain’s emergency battery pack.
It rapidly regenerates ATP when demand spikes.

In both Parkinson’s and Alzheimer’s, this energy system breaks down.
Mitochondria fail. Neurons starve.

#BrainHealth #Mitochondria

🚨 BREAKING Scientists may have just cracked the code on Alzheimer's and Parkinson's — WITH ONE PILL.

A drug called Buntanetap was just published in a peer-reviewed journal with Phase 3 data.
Phase 3 means that we are on the verge of FDA approval.

It targets the ROOT CAUSE of both diseases simultaneously.

Here's what you need to know 🧵👇
#Alzheimers #Parkinsons Tweet 2
Most people think Alzheimer's and Parkinson's are totally separate diseases.
They're not.

At autopsy, ~1 in 3 Alzheimer's patients have Lewy body (Parkinson's-type) protein in their brain.

And ~50% of Lewy body dementia patients have full Alzheimer's pathology too.

Same brain. Multiple diseases. Quietly overlapping. 🧠
That's called co-pathology — and it's why targeting just one protein may never be enough. 👇
#Dementia #Neurodegeneration

🚨 Scientists just identified a hidden 'molecular switch' that drives chronic brain inflammation in Alzheimer’s.

It’s a protein called STING that gets chemically stuck in the “on” position.

This could be a major new drug target. Thread 👇 From Scripps Research
published April 2026, highlighted again recently

In Alzheimer’s brains, STING undergoes a specific chemical modification (S-nitrosylation) → this keeps microglia (brain immune cells) in chronic overdrive, damaging neurons and synapses.

We've spent decades hunting for "the ALS cure."

I get it … when you're facing this disease, you want one answer. That's human.

But after 20 years in neurodegeneration, I can tell you: we've been asking the wrong question.

And new science proves it. Here's what's actually going on.

#ALSAwareness #PrecisionMedicine Here's what I mean.

ALS … amyotrophic lateral sclerosis … is the name we give to a disease where motor neurons die.

But the biological reason they're dying? That differs from patient to patient.

Same diagnosis, but completely different machinery … breaking down underneath.

That's the part nobody told patients. And it matters more than almost anything else in ALS right now.

🚨 BREAKING:
Parkinson's disease may begin in your GUT — not your brain.

Peer-reviewed science now shows gut changes can precede motor symptoms by 10–20 YEARS.

And a deficiency in specific B vitamins may be driving the damage.
Thread 🧵👇 Before the tremors. Before the diagnosis.

Researchers consistently find these GI symptoms in people who later develop Parkinson's:
❌ Chronic constipation
❌ Delayed stomach emptying
❌ Bacterial overgrowth (SIBO)
❌ 'Leaky gut.'

This isn't a coincidence. It's the disease.

🚨 BREAKING Scientists just gave 15 people a single IV drip.
No daily pills.
No monthly injections.
One time.
Done.

Their "bad" cholesterol dropped 50%.
Triglycerides dropped 55%.

And it may be PERMANENT.

This is CRISPR — and it just changed cardiology forever. 🧵 The drug is called CTX310.
It's made by CRISPR Therapeutics.

Here's how it works in plain English:
Your liver makes a protein called ANGPTL3.
That protein BLOCKS your body from clearing cholesterol.

CTX310 turns that gene OFF.
Permanently.

Like flipping a switch — and never having to flip it again. 🔬

BREAKING: Scientists gave 20 patients a single cancer treatment.

All 20 had ZERO detectable cancer cells afterward.
None progressed.
None died.
This just published in Nature Medicine.

Here's what it actually means 🧵👇 The treatment is called CAR-T cell therapy.
Here's how it works:
→ Doctors take YOUR own immune cells
→ Re-engineer them in a lab to hunt cancer
→ Infuse them back in ONE single dose
Your own immune system becomes the weapon.
(2/10)

BREAKING: An AI just designed a drug that restored motor function in Parkinson's disease models.

The FDA cleared it for human trials in January 2026.
This is not sci-fi.
This is happening NOW.
Thread 🧵👇

#Parkinsons #AIinMedicine #NLRP3 Parkinson's Disease in numbers:
• 2nd most common neurodegenerative disease
• 25 MILLION projected cases by 2050
• Current drugs? They only MASK symptoms • Levodopa — the gold standard — was developed in the 1960s
However science is growing and the landscape geared towards Parkinson’s is moving forward.
I explained this in April 2026 with a master landscape highlighting over 200 clinical trials.
There true genuine hope for Parkinson’s!!👇

BREAKING:
New clinical trials show NAD+ supplements can SLOW the loss of walking speed and grip strength in people over 65.

Your body makes less NAD+ every decade after 40.

These trials show you can get it back.

Thread below 👇 NAD+ is the molecule your cells use to make energy.

By 60 you have roughly half what you had at 20.

NMN and NR are the two supplements being tested to restore it.

Both are forms of Vitamin B3.
Both are taken as a pill or powder.
Both have human clinical trial data.

That's the whole idea. Here's what the science shows 👇

🚨 BREAKING:
Scientists just found a SPECIFIC sugar molecule made by gut bacteria that appears to TRIGGER ALS and dementia.

70% of ALS/FTD patients had it.
Only 33% of healthy people did.

And they found a way to STOP it. 🧵 Published January 2026 in Cell Reports.

Case Western Reserve University researchers spent years tracking why people with the same ALS gene sometimes get the disease — and sometimes don't.

The answer was hiding in their gut the whole time. 👇

BREAKING 🚨 Scientists are clearing 'zombie' cells from the brain to STOP Alzheimer's.

The first clinical trial just proved that the drug reaches the brain.
Phase 2 is underway now.

This is one of the most exciting AD trials in decades.
A thread 🧵↓ First, what is a 'zombie cell'?
In science: a SENESCENT CELL.
It stops dividing. But refuses to die.

Instead, it leaks toxic chemicals — attacking your brain 24/7.

As we age, they pile up.
In Alzheimer's patients? They pile up even faster. 🧠⚡
