Brain fog can persist 8 months after COVID diagnosis. Prominent cognitive impairments included processing speed (133 [18%] were impaired), executive function (118 [16%]), phonemic fluency (111 [15%]), category fluency (148 [20%]), memory encoding (178 [24%], and memory recall (170 [23%])

Of note is that participant scores were compared to demographic norms rather than to their own performance before COVID infection. For obvious reasons. But seeing that these participants were recruited through the hospital (i.e. they were currently engaging with the healthcare system as patients in some way), it is very possible that they simply performed worse than the norm due to current health issues rather than their history of COVID.

From the article it looks like they were comparing outpatient performance with inpatient performance.

No covid made them tarded

Wonder how smart these people in the study were before covid.


tutier09

Personal anecdote: I was really smart before (never took an IQ test but apparently I taught myself how to read before kindergarten and I started studying at uni 3 years earlier than usual in my country). After Covid I was too stupid to drive a car or to follow easiest instructions (like “turn left and enter the second door on the right”). Over the months it got better - with frustrating and tiring training. Now, more than 1 1/2 years later I think I would be able to follow a beginners maths course at uni but it would be very challenging. I still don’t have my old cognitive abilities back. I’m ok with it though. Sometimes it is still frustrating but honestly I’m glad that I can live a normal life without help, that I can work in my job and have conversations with people. All this seemed out of reach for months, leaving me on the brink of suicide.


TheGasIsLit

I can say that I was very smart. Had a great career and was very driven. I had to change fields and still struggle. My short term memory is terrible. I don’t remember a lot of my kids lives. I lost the ability to speak my other languages (Korean and Spanish) languages and my vocabulary which has always been great is down to high school level. It awful.


ImWhatTheySayDeaf

Completely a personal anecdote, I had Covid in March 2021 and it was a moderate case where I was sick for 2 weeks. I've had this brain fog since that time. It's weird but I definitely feel "off" ever since. Now, I did get vaccinated and I have noticed an improvement so I'm hopeful it'll continue to get better but, personally, I can attest to this ongoing issue being legit.


[deleted]

I had the brain fog for a month. I felt like I was moving in slow motion. It's absolutely a terrible feeling.


themixtape27

Same deal for me too, sick for two weeks in early January but never hospitalized. I work in an artistic field and didn’t have a ton of sick days so I resumed (remote) work as soon as I could. I felt totally empty of creativity, new ideas, and strategic thinking for ages. Every week I felt a little bit better and could realize just how much of a daze I was under the week before, but it was difficult to objectively see how I was performing at the time. It took at least six months for me to actually feel like myself again. I wish more people considered lingering side effects like these instead of always focusing on whether or not COVID is likely to kill you


Fishy1911

This is one of the reasons I got vaccinated as soon as I could, fear of the mental fog.


lazylaser97

One of my peers has taken a huge step back since being intubated for 3 weeks. Was it the virus? Or the lack of oxygen leading to intubation. Either way it's awful.


Fishy1911

That sucks. How they pull through. Doesn't sound like they'll come through unscathed.

Adult COVID-19 patients who were hospitalized or visited the emergency department (ED) at a New York City hospital still had cognitive impairments an average of 8 months after diagnosis, according to a research letter today in JAMA Network Open. Researchers at Icahn School of Medicine at Mount Sinai evaluated 740 COVID-19 inpatients and outpatients using validated neuropsychologic tests in April and May 2021. Average time since COVID-19 diagnosis was 7.6 months. Participants had no history of dementia. The aim was to better characterize the relationship between COVID-19 severity and persistent cognitive problems, often called "brain fog," because previous studies have had small sample sizes and lacked optimal measurement of cognitive function, the researchers said. The neuropsychologic tests included Number Span forward (to gauge attention) and backward (working memory), Trail Making Test Parts A and B (processing speed and executive function, respectively), phonemic and category fluency (language), and the Hopkins Verbal Learning Test-Revised (memory encoding, recall, and recognition). Executive function involves working memory, flexible thinking, and self-control. http://jamanetwork.com/journals/jamanetworkopen/fullarticle/10.1001/jamanetworkopen.2021.30645?utm_source=For_The_Media&utm_medium=referral&utm_campaign=ftm_links&utm_term=102221

Do the vaccines prevent this?

MastersYoda

Honestly sounds like adhd and brain trauma.


UnderneathTheMinus80

I agree, the driver of both conditions you mentioned is inflammation. Some autoimmune diseases can cause inflammation in the brain too. And, you guessed it, brain fog is a symptom of autoimmune diseases.


capnJayd

I'm a breakthrough case. I'm a little over 2 months since initial infection. Brain fog has been rough, I definitely have troubles with nouns. I'm tired and weak constantly. But the vertigo/dizziness is the worst part.


gsoClarke

Another personal anecdote, for three and a half months after getting my two modern jabs in the spring, I had a problem calling up nouns. I noticed it pretty soon it mentioned it to my wife and continued pointing it out when I was having trouble. It was weird, just now, but it reminded me of several older couples I knew. The men would try to recount episodes until stories, but they frequently stumbled over the nouns. The wives had to still in the blanks for them. The men had no problem with verbs, adjectives, and adverbs... only nouns. I'm fine now.


chalupacabrariley

I’ve been struggling with this for close to a year now. I can picture the word I’m trying to say in my head, but actually finding the word is difficult.


ghettosupermom

Been suffering longer than 8 months

If you have persistent effects of covid, it's called long-haulers syndrome. You should look into a drug called Leronlimab, made by Cytodyn.com. They're the only company with a cure in the works.


danielbojangle

The FDA isn't happy with that company or their alleged COVID cure. Might want to [read](https://www.biospace.com/article/fda-torpedoes-cytodyn-s-leronlimab-for-covid-19/) up on it


Cr4mwell

That article is a spin on the truth and omits a lot of information. You should probably continue to do research if you're actually interested in the topic. If that article was at all accurate then why did the FDA allow the company to continue trials and start a covid long hauler trial?
