Potential earlier onset of Alzheimer's. Maybe as much as 25 years

[AnxiousNoMore]

It is possible that you have far greater risk of Alzheimer's alone than what you are worried about (not sure if Covid causes Alz.. but the article says it seemed to accelerate the process) if future studies confirm what these docs suspect. https://www.ctvnews.ca/health/coronavirus/covid-19-could-serve-as-a-trojan-horse-for-dementia-and-alzheimer-s-experts-say-1.5568918

"... a massive acceleration in cognitive decline in individuals who were harboring Alzheimer’s disease (AD) in their brains, but who, up to that point, were mostly combating it and showing very little symptoms,” he said."

Note I said "It is possible" in the first sentence.  
Your post >"Note it says "could."  Doesn't say does. "

"he first started to notice the problem last fall, when several patients in their 50s showed fast deterioration of their cognitive functions." Without the suspected effect of Covid, these people wouldn't have had this steep decline (unknown exactly how quick it would have happened to them but somewhere up to 25 years) in the future. Therefore their families would agree with the doc that it increased the onset by up to 25 years..

That's not scientific evidence, for God's sake.  Alzheimers doesn't occur that quickly.  It takes many many years to develop it.  If covid did anything at all it would have speeded up a process that was already underway by a little bit.  But again, given the blood clot problem with covid and the brain fog and the rest, it would seem to me much more likely if there is dementia it isn't Alzheimers.  I don't think they're going to find someone who has no amyloid plaques and other signs of Alzheimers were not there at all and then suddenly appeared due to covid.  But if anyone other than the couple of docs mentioned in the article are concerned enough, research will be done, and we'll see, but again, if it takes 12-25 years for Alzheimers to fully develop, how can covid cause it in a few months?  It had to have already had a real good head start, based on what we currently know about the disease.  Of do you want to cut open people's brains when they get covid and then see if they are free of all signs of Alzheimers and then sew them back again and see if the get it?  What this doc and those families think isn't scientific, it's a guess.  I'm guessing they're wrong, but I don't know, and we'll all find out, but I wouldn't suggest folks out there worry about it, if it was happening a lot we'd know by now.  We know all the other things long-haul sufferers are having.  So let's stop this.  You think we should all be very very scared and I don't.  Well see, and anyone reading this can make their own decisions based on one anecdotal article in one magazine.

Poor reading comprehension on your part. I will only comment on this first quote of yours because it's so far off the mark.
"First of all, it didn't say it increases the onset by 25 years.  It says Alzheimer's now appears to start 25 years before any signs are noted.  No relation there to covid."

People who got Covid who didn't have any problem with Alzheimer's now got Alzheimer's. Therefore a potential 25 year development period seems to have got wiped out. "... a massive acceleration in cognitive decline in individuals who were harboring Alzheimer’s disease (AD) in their brains, but who, up to that point, were mostly combating it and showing very little symptoms,” he said."
Of course you can look at the title and get some clue to the content in the article  "covid-19-could-serve-as-a-trojan-horse-for-dementia-and-alzheimer-s-experts-say"

Note it says "could."  Doesn't say does.  There is no current hard diagnosis of Alzheimer's available until you're dead, unless you want someone cutting open your brain while you're alive.  It's defined by a set of symptoms, and that could include other forms of dementia.  Alzheimer's is the leading form folks get, but with covid, given the blood clots, it could be said it seems more likely to be a different form.  The patients they were looking at were old.  Here's the quote:  "He told CTVNews.ca that the decline that leads to Alzheimer’s generally starts 15-25 years before symptoms show up, and that diagnosis takes a couple years after that in most cases."  Look, you often post things that are quite scary, and it doesn't help anyone to get scared.  I just look at the stuff and see if it's as scary as what you post because life is hard enough without getting even more scared of it.  I never said you were wrong.  I said you weren't necessarily right, which is accurate.  Let everyone read the quote from the article you cited and see who can read.

Not exactly what the article said, so let's tamp down the fear a bit.  First of all, it didn't say it increases the onset by 25 years.  It says Alzheimer's now appears to start 25 years before any signs are noted.  No relation there to covid.  What has been widely reported by anyone who has been keeping up with the news, some people suffer long-haul covid, and those are the people these docs are concerned about.  They have reported neurological symptoms such as worse memory, brain fog, and such that are also identified with those who have dementia, but it should be stated that lots of other things also cause these things, including for some depression, anxiety, and lots of medications.  It would stand to reason that since covid has mostly killed the old they would find more signs of Alzheimer's when they look at their brains.  A lot of the diagnosis of Alzheimer's happens after death.  Since I don't believe we actually know yet what causes Alzheimer's it would be impossible to say there are signs of Alzheimer's, but dementia can include other types such as that caused for some who have strokes and other vascular problems.  I guess I'm saying, don't get terrified out there, the docs are calling for studies, not saying it's been proven to be happening now, so they can get ahead of it, though I have no idea what that would do as we have no treatment for Alzheimer's or even know if someone has it until they are very far into it.  The article also states that certain proteins are found in Alzheimer's, but they really don't know if they are causative or a result.  I would say, let's worry about what's in front of us right now and not stir up a panic about something they don't understand even in those who already have it.  They also noted that there is actually less Alzheimers around right now, but not for a good reason, it's because so many old folks died of covid.  So yeah, it's possible.  It's possible a meteor will hit your house today.  I wouldn't worry about it right now, though, we need to focus on what we know is happening, and we still don't know if long-haul covid is permanent or temporary as the virus has only been with us for a short time.  Not saying anything noted is wrong, just that nothing is now known, it's a theory, and they are calling for resources being put into it now rather than waiting.  Peace, all.
