I’ve spent two decades studying how brains age. And I’ve never seen anything quite like this.
In normal aging, some neurons die—but it’s gradual, region-specific, and the brain compensates remarkably well. Most of what we see is driven by loss of synaptic connections, not widespread neuron death. Behavioral changes tend to be slow, subtle, and mostly involve executive function.
In neurodegenerative diseases like Alzheimer’s and Parkinson’s, it’s different. These diseases kill neurons. The decline is faster, deeper, and more functionally disabling.
What we’re seeing in young adults after SARS-CoV-2 infection doesn’t fit either pattern. We’re seeing signs of early, widespread cognitive impairment—slowed thinking, weakened memory, executive dysfunction. Not just in one domain. Not just in one region. Almost every study that looks for brain damage post-infection finds it.
This suggests accelerated neural de-differentiation—a breakdown in how specialized brain regions communicate and function. It's something we normally see decades later.
Impairment doesn’t always mean permanent disability. But if neurons are dying, those cells aren’t coming back. And yes—cognitive disabilities have also spiked dramatically since 2020. There’s no other plausible explanation for the scale and timing of this trend.
Meanwhile, self-styled truth-tellers with zero background in neuroscience or cognition keep minimizing the risks—spreading the idea that these impairments are rare, minor, or imagined.
Speak up with evidence? You’re called an extremist. Refuse to play along? You’re accused of fear-mongering.
My biggest mistake? Thinking these folks were just misinformed. They’re not. They’re propagandists.
It’s 2025. The damage is measurable. The science is clear. And the longer we pretend this is normal, the worse the outcomes will be.
I don't know how to solve this problem in a free market but when I signed up for gmail, it was advertised as "free unlimited email forever". That's what I signed up for
Now I have to pay Google or get rid of half my email. I feel tricked.
I have just had the craziest morning.
I meet up twice a year with five colleagues to coordinate an annual event.
When I arrived the first two were already there...
@thephysicsgirl@992tobias Thanks for standing up for your new friend, yourself and all the others who suffer from this disease. You got all the skills and followers to have a deep impact. Thank you for being a true advocate
A new study shows that air cleaners can reduce up to 98,1 % of viral load in the air of a #COVID patient's room with confirmed positive airborne viral RNA.
Rooms with HEPA ventilation had zero virus detected.
👏 #CleantheAir in hospitals and schools!👏

Arg. I'm just going to bash through a messy thread.
I've been whacking my head against this data for three months after looking it up, and it's only got worse for the last three months.
It's about that question "are people still getting sicker".
Summary in the next tweet...
🔥🩸 Oh here we go again.
More evidence for doctors, journalists, governments and everyone to ignore:
Covid messes with how your body moves blood around.
This time, it’s the capillaries, the tiniest blood vessels that keep every part of your body supplied with oxygen:
If it is not clear yet, there is a disconnect in what people are experiencing, scientists seeing, and government's priorities. It's a worldwide problem.
If any media outlets want to cover this scandal, I have a collection of DMs from #LongCovid patients offering me their brains.
A lot of people have noticed it. In the past few years, a bunch of different infections in England have started moving together.
Spikes, dips, rising and falling in sync.
@Dave_it_up You know it is the lockdowns causing this. Especially the Swedish lockdown...
Sarcasm.
Thanks for sharing this. I wonder how infections by different covid strains impacts this.
