Covidiot Antivaxxer News - Study Shows That Covid-19 Can Cause Dementia

COVID-19 Pneumonia Increases Dementia Risk - MU School of Medicine

There are two ways of looking at the latest findings concerning the long-term effects of severe COVID-19.
  • If you are a creationist, you could marvel at the inventive genius of any intelligent designer who could design such a thing as the SARS-CoV-2 virus that causes COVID-19 just to increase the suffering in the world
  • If you are a caring and compassionate person, you can appreciate how this findings makes it imperative that as many people as possible are vaccinated and boosted in order to reduce the likelihood of someone else catching the disease and to help make the pandemic a thing of the past.
The finding, by researchers from the University of Missouri School of Medicine and MU Health Care shows that there is a significantly increased risk of developing dementia following a case of COVID-29-induced pneumonia, severe enough to requiring hospitalization.

The risk of new onset dementia was more common in COVID-19 pneumonia patients over the age of 70 in our study.

The type of dementia seen in survivors of COVID-19 infection mainly affects memory, ability to perform everyday tasks and self-regulation. Language and awareness of time and location remained relatively preserved.

The findings suggest a role for screening for cognitive deficits among COVID-19 survivors. If there is evidence of impairment during screening and if the patient continues to report cognitive symptoms, a referral for comprehensive assessment may be necessary.

For the study, the researchers analysed the records of 1.4 billion medical encounters prior to July 31, 2021. They selected patients hospitalized with pneumonia for more than 24 hours. Among 10,403 patients with COVID-19 pneumonia, 312 (3%) developed new onset dementia after recovering, compared to 263 (2.5%) of the 10,403 patients with other types of pneumonia diagnosed with dementia. This represents a 20% increase in the risk of dementia following COVID-19 pneumonia.

The study was only of new onset dementia. The median time interval between infection and dementia diagnosis was 182 days for COVID-19 patients. The study only included new onset dementia associated with hospital admission during a short follow-up period. Dr Qureshi said a more detailed study, conducted over a longer time may help to determine the reasons why COVID-19 is linked to dementia.
The authors give more details in the abstract to their open access paper published in the journal Open Forum Infectious Diseases:


Case series without control groups suggest that severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection may result in cognitive deficits and dementia in the postinfectious period.

Adult pneumonia patients with SARS-CoV-2 infection (index hospitalization) and age-, gender-, and race/ethnicity-matched contemporary control pneumonia patients without SARS-CoV-2 infection were identified from 110 healthcare facilities in United States. The risk of new diagnosis of dementia following >30 days after the index hospitalization event without any previous history of dementia was identified using logistic regression analysis to adjust for potential confounders.

Among 10 403 patients with pneumonia associated with SARS-CoV-2 infection, 312 patients (3% [95% confidence interval {CI}, 2.7%–3.4%]) developed new-onset dementia over a median period of 182 days (quartile 1 = 113 days, quartile 3 = 277 days). After adjustment for age, gender, race/ethnicity, hypertension, diabetes mellitus, hyperlipidemia, nicotine dependence/tobacco use, alcohol use/abuse, atrial fibrillation, previous stroke, and congestive heart failure, the risk of new-onset dementia was significantly higher with pneumonia associated with SARS-CoV-2 infection compared with pneumonia unrelated to SARS-CoV-2 infection (odds ratio [OR], 1.3 [95% CI, 1.1–1.5]). The association remained significant after further adjustment for occurrence of stroke, septic shock, and intubation/mechanical ventilation during index hospitalization (OR, 1.3 [95% CI, 1.1–1.5]).

Approximately 3% of patients with pneumonia associated with SARS-CoV-2 infection developed new-onset dementia, which was significantly higher than the rate seen with other pneumonias.

The findings from this study, with the findings in the study which was the subject of my last blog post which showed the efficacy of the vaccines in children, give a very clear message to anyone with a sense of social responsibility, which I appreciate tends not to include evangelical creationists and members of extremist right-wing antivaxxer cults, is that vaccinations work and should be encouraged, if we are ever to put an end to this pandemic and to reduce the suffering it has wrecked worldwide.

Probably what evangelical creationists hate most about the vaccines is that they represent a considerable triumph of science over what they believe to be the creation of their god, visited on mankind for disagreeing with evangelical creationists.

Don't be a Covidiot!
Get vaccinated or get boosted, Now!

Thank you for sharing!

  1. Things that could have been if I had known about Covid before I caught it. I was bottling at my daughter's distillery back in December 2019 along with a small group (about 8 adults), and was talking to a guy who had just come back from working in China. This was before anyone knew about Covid. As it happened, both me and my wife got really sick a few days later as did everyone else who had volunteered that day. Seemed like a bad flu, but it was the sickest I've ever been in my life. We didn't need to go to the hospital, and mostly recovered a few days later. But it took a bit longer to get over it completely. Both me and partner have been vaccinated and both have received the second booster, but in regards to your article, I now have to wonder whether or not I've been affected. Chances are good that we're ok since only 3% have developed dementia, but it is a real concern. Thanks for the post. I will read the study as my next project...

    1. As I understand it there was only a link between the sever form of COVID requiring hospitalisation and dementia, with a mean onset time of 182 days, so, if you are well past that median time and didn't need to go to hospital, you probably have nothing to worry about.

      For what it's worth, early in January 2020, my former partner and I spent the day in London in a crowded art gallery, and travelled on a packed underground train. Within a few days, we both developed very heavy colds/flu. If we had had the same symptoms today, we would assume we had COVID.
