Iāve spent two decades studying how brains age. And Iāve never seen anything quite like this.
In normal aging, some neurons dieābut itās 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 Alzheimerās and Parkinsonās, itās different. These diseases kill neurons. The decline is faster, deeper, and more functionally disabling.
What weāre seeing in young adults after SARS-CoV-2 infection doesnāt fit either pattern.āØWeāre seeing signs of early, widespread cognitive impairmentāslowed 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-differentiationāa breakdown in how specialized brain regions communicate and function. It's something we normally see decades later.
Impairment doesnāt always mean permanent disability. But if neurons are dying, those cells arenāt coming back. And yesācognitive disabilities have also spiked dramatically since 2020. Thereās 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 risksāspreading the idea that these impairments are rare, minor, or imagined.
Speak up with evidence? Youāre called an extremist.āØRefuse to play along? Youāre accused of fear-mongering.
My biggest mistake? Thinking these folks were just misinformed.āØTheyāre not. Theyāre propagandists.
Itās 2025.āØThe damage is measurable.āØThe science is clear.āØAnd the longer we pretend this is normal, the worse the outcomes will be.
Significant, long-lasting cognitive impairments in young adults. Verbal working memory was significantly impaired lower performance in divided attention & response inhibition.
The observed increased reaction time in all cognitive tasks may demonstrate cognitive slowing.
