The cognitive decline could reach up to nine points in some cases, scientists have claimed
The long-term consequences of Covid-19 could include decreased cognitive abilities and memory deficiency, a new large-scale study has found.According to research published in the
New England Journal of Medicine on Thursday, patients who had recovered from coronavirus symptoms had a cognitive deficit equivalent to three IQ points compared with those who had never been diagnosed with it. Meanwhile, study participants with unresolved persistent symptoms had an IQ decline of six points.
The Covid impact was even more pronounced when it came to those who were admitted to the intensive care unit, with the IQ loss reaching nine points compared to the control group. At the same time, the scientists "observed a small cognitive advantage among participants who had received multiple vaccinations," the research claims.
The study said that there are "multiple underlying factors" that contribute to post-Covid cognitive decline. "Our results confirmed associations of cognitive deficits with mood swings and fatigue but also with a variety of other symptoms," researchers said.
The Journal's editorial dedicated to the study called its results concerning, given the scope of the Covid-19 pandemic, noting that "the broader implications require evaluation."
At the same time, the results indicated that
those who suffered cognitive decline due to persistent Covid symptoms could later regain part of their ability, reaching the level of those who managed to recover quickly.A total of 800,000 people were invited to take part in the study in England, with around 113,000 completing it. The participants were asked to do a number of online tests to evaluate their cognitive abilities. One of the major caveats of the research, however, was the
lack of data on participants' IQ level before they contracted Covid, which meant that their cognition was measured against those who did not have the disease rather than their own abilities.According to World Health Organization data, there have been a total of 774 million recorded Covid cases globally, with seven million reported deaths. Apart from an apparent cognitive decline, the long-term effects of Covid could include chronic pain, brain fog, shortness of breath, chest pain, and fatigue.

Cognition and Memory after Covid-19 in a Large Community Sample
The same day a communication appeared in the same journal:
Prospective Memory Assessment before and after Covid-19 and they write:
In a group of Norwegian participants assessed between March 2020 and April 2023, participant-reported memory function, as scored on the EMQ [Everyday Memory Questionnaire], was numerically worse at several time points up to 36 months after a positive SARS-CoV-2 test than after a negative test.

4)There have been studies that explore the relationship between hippocampus and various conditions. Below are a few examples:
Psychopathy and the Hippocampus
The degree of subjects' psychopathy was studied using the Psychopathy Checklist - Revised (PCL-R) and an inverse correlation was found - the smaller the hippocampi, the more severe the degree of psychopathy. The strongest correlations were found in the posterior hippocampus. The posterior hippocampus is know to participate in processes, such as conditioning and forming associations. This is the first study to date to find structure-function (or structure-malfunction) correlation in terms of degree of psychopathy.
Birds in Captivity Lose Hippocampal Mass (Does this also happens for humans?)
Caged birds may still sing, but being in captivity for just a few weeks can reduce the volume of the hippocampus by as much as 23 percent, according to a new Cornell study. The hippocampus is the part of the brain involved in spatial learning and memory tasks.
Study shows recurrent depression shrinks area of brain responsible for forming new memories
A study published in Molecular Psychiatry today has proved once and for all that recurrent depression shrinks the hippocampus - an area of the brain responsible for forming new memories - leading to a loss of emotional and behavioural function.
Hormones, Hysterectomy and the Hippocampus (Why is that no being highlighted when they advertise for gender surgery?)
In the current study, removal of the ovaries and the associated long-term estradiol deprivation made the hippocampus hypersensitive to ischemic stressors and induced a myriad of events leading to significant hippocampal CA3 cell damage and cell death. The long term estradiol deprivation also led to increased amyloid production and associated neurodegeneration. As one might expect, damage and disruption to the hippocampus, the brain's memory center, was associated with the animal's ability to learn, remember and function.
How a Mother's Love Changes a Child's Brain (The attack on the traditional family is hardly a plus?)
Previous animal research showed that early maternal support has a positive effect on a young rat's hippocampal growth, production of brain cells and ability to deal with stress. Studies in human children, on the other hand, found a connection between early social experiences and the volume of the amygdala, which helps regulate the processing and memory of emotional reactions. Numerous studies also have found that children raised in a nurturing environment typically do better in school and are more emotionally developed than their non-nurtured peers.
Brain images have now revealed that a mother's love physically affects the volume of her child's hippocampus. In the study, children of nurturing mothers had hippocampal volumes 10 percent larger than children whose mothers were not as nurturing. Research has suggested a link between a larger hippocampus and better memory.
More than 150 comparative studies and articles on mask ineffectiveness and harms
"The rebreathing of our exhaled air will without a doubt create oxygen deficiency and a flooding of carbon dioxide. We know that the human brain is very sensitive to oxygen depravation. There are nerve cells for example in the hippocampus, that can't be longer than 3 minutes without oxygen - they cannot survive. The acute warning symptoms are headaches, drowsiness, dizziness, issues in concentration, slowing down of the reaction time - reactions of the cognitive system. However, when you have chronic oxygen depravation, all of those symptoms disappear, because you get used to it. But your efficiency will remain impaired and the undersupply of oxygen in your brain continues to progress. We know that neurodegenerative diseases take years to decades to develop. If today you forget your phone number, the breakdown in your brain would have already started 20 or 30 years ago...The child needs the brain to learn, and the brain needs oxygen to function. We don't need a clinical study for that. This is simple, indisputable physiology. Conscious and purposely induced oxygen deficiency is an absolutely deliberate health hazard, and an absolute medical contraindication."
Scientific evidence suggests the vaccine-autism link can no longer be ignored (From 2013, so this is old, but has been ignored nevertheless.)
The studies also show that children from countries with the highest ASD appear to have a much higher exposure to Aluminum from vaccines. The study points out that several prominent milestones of brain development coincide with major vaccination periods for infants. These include the onset of synaptogenesis (birth), maximal growth velocity of the hippocampus and the onset of amygdala maturation.
