Scientists discover that even mild COVID-19 can alter brain proteins linked to Alzheimer’s disease, potentially increasing dementia risk—raising urgent public health concerns.

Get vaccinated, y’all.

[u/mb2231 → u/Corleysaurus]

The study makes it sound like it wouldn't matter.

I've gotten the COVID vaccine each year and already have had COVID two times. It was mild but the study specifically says that mild COVID can be a contributor.

[u/SaltZookeepergame691 → u/mb2231]

The largest “effect” (which has limitations) is explicitly in the sickest people - vaccination should absolutely help. It isn’t binary.

[u/Corleysaurus → u/mb2231]

Yes, but, being vaccinated can largely prevent severe COVID cases/hospitalization, which the article indicates is connected to a worsening of this issue.

[u/Think_Discipline_90 → u/mb2231]

What kind of logic tells you mild vs severe carries the same risk?

[u/aguyinphuket → u/Think_Discipline_90]

Perhaps not the same risks, but there is not necessarily a direct correlation between the severity of pulmonary symptoms caused by COVID infection and the severity of the damage to proteins in the brain such an infection can cause.

[u/Think_Discipline_90 → u/aguyinphuket]

Anything is possible, yes.

[u/fadingsignal → u/Think_Discipline_90]

It's not logic, studies point to this. People are still too focused on the acute phase of COVID (rightly so considering how it behaved in early 2020.) But it gets everywhere through the body and causes myriad downstream issues we still don't understand.

Here's one about neurological effects and how severity or vaccination doesn't affect outcome:

Here's one on how long-COVID appears to stem more from mild cases than acute ones:

Scientific method. You are making an assumption

[u/Think_Discipline_90 → u/[deleted]]

I am, and so is he. Haven't tested either hypothesis, so it's best to assume vaccines still help.

[u/[deleted] → u/Think_Discipline_90]

No. It's best not to assume and get proper studies done.

[u/Think_Discipline_90 → u/[deleted]]

Okay. Then stop taking vaccines until we have figured out the universe.

[u/Think_Discipline_90 → u/[deleted]]

You know you're just being annoying and pedantic now. Probably mid college age?

[u/Think_Discipline_90 → u/[deleted]]

Okay I will thanks bye

[u/fadingsignal → u/mb2231]

There was also some new information that vaccinated or not, severe or mild, didn't matter when it came to the neurological outcomes from COVID infections. Vaccines cut death/acute severity way down, but verdict is out on all of the other myriad damage COVID is still doing through the body. We don't know enough about COVID to let it rip like we did.

According to new research published in Brain Communications, Northwestern Medicine researchers found that vaccination prior to COVID-19 infection did not significantly affect neurological symptoms in long COVID patients, both in patients who had a severe infection that required hospitalization and those with a mild infection who did not require hospitalization. Common neurological symptoms of long COVID include brain fog, numbness and tingling, headache, dizziness, problems with smell and taste and intense fatigue.
