Surging aggression. Language delays. Developmental issues. Teachers & parents report major changes in children

Lockdowns are often blamed. But many lockdowns were short (e.g. UK)

So what else changed in early childhood since 2020?

I’m a neurologist. Let's talk COVID & brains🧵

Let's be clear: lockdowns may have had an impact on some children, especially in unsafe homes or w/poor digital access. That shouldn't be denied.

But what we're seeing now goes far beyond what short-term isolation would explain, especially in children born after lockdowns ended.

Babies aren't socialised in their first 2-3 months to protect their fragile immune systems. Instead, they focus on bonding with caregivers.

So blaming lockdowns for behavioral issues in babies born during or after 2020 ignores the major factor: widespread infections in infancy.

Since 2020, UK children (incl infants) have been repeatedly infected with SARS-CoV-2:

- A virus that enters the brain
- Damages grey & white matter
- Shrinks the frontal cortex
- Alters neurological development

This is even after mild & asymptomatic infections.

The frontal lobe governs:

- Impulse control
- Language acquisition
- Emotional regulation
- Social behaviour
- Attention & learning
- Empathy

Subtle damage during development can profoundly affect behaviour and cognition.

Teachers are reporting:

- More violence, even in reception and Key Stage 1
- Children hitting staff & peers
- Difficulty with attention & following instructions
- Emotional volatility
- Delays in speech, literacy, writing, and social development

This is systemic. And new.

UK lockdowns were short-lived:

- Nurseries & early years reopened June 2020
- All year groups returned to school in September 2020
- Under-5s faced few social restrictions

Yet the youngest cohorts, many born after lockdowns, are showing the most concerning outcomes.

Why?

Here's what changed... mass infection became policy:

- No clean air in schools
- No real protections for staff or students
- No vaccines for under-5s
- Reinfections normalised, even encouraged to achieve "herd immunity"

COVID became routine for children.

That has consequences.

COVID is not just a respiratory virus.

It's neuroinvasive. It can:

- Cross the blood-brain barrier
- Persist in neural tissue
- Trigger brain inflammation
- Shrink the frontal cortex
- Affect white matter, connectivity, cognition

Even in mild /asymptomatic illness.

Even children born after lockdowns ended, who missed the brunt of restrictions, are showing worrying developmental trends:

- Delayed speech
- Poor attention span
- Trouble with emotional regulation
- Language & learning gaps

Kids will have had 3-6 covid infections before age 6.

Meanwhile, children who lived through the peak pandemic years are now in classrooms, and teachers are reporting:

- Violent outbursts
- Severe attention issues
- Struggles with empathy, self-control, and literacy

This points to something deeper than just lockdowns.

Multiple studies show COVID-19 affects developing brains:

🧠 Infants born to infected mothers show altered brain structure
🧠 Children post-covid show cognitive delays and inflammation
🧠 Even mild cases leave long-term neurological footprints
🧠 Risk grows with each reinfection

In short:

UK children are being repeatedly infected, often within their most vulnerable developmental windows, by a virus that damages the brain.

We are normalising this. Ignoring it. Blaming everything but the virus itself.

That is a societal failure of staggering proportions

This thread isn't about fear, it's about recognition

Lockdowns had an impact, yes, but something else is driving this

We owe it to children to ask the hard questions

To protect them from repeat brain injury that may alter their development, and their futures, permanently

It should come as no surprise that this situation ⬇️ is quickly deteriorating, having been reported on TODAY.

“Disturbing rise in domestic abuse among 16 to 25 year olds”

“Children as young as nine are asking about violent pornography and displaying misogynistic behaviour.”

I have no idea why Twitter/X decided to remove the images from the initial post in the thread, and instead write out a link for the tweet as a replacement.

But here is what was originally attached:

I would like to address today’s news that A-Level results have “risen again” and “top grades are up”, when this is in complete contradiction to the bulk of this thread.

My quoted thread below deals with this phenomenon and explains exactly what is going on here…

“Should be of concern to all of us”

Yet they turn a blind eye to the root cause of the problem.

These are our policymakers.

Frightening really.

(This is Canada, the problem is ubiquitous)
