In a new study, researchers examined the cognitive impacts of COVID-19 on people with dementia. They found that having COVID-19 rapidly accelerated the structural and functional brain deterioration of patients with dementia, regardless of the type of dementia being experienced.

Over 10% of children in Japan with COVID-related brain disease died, survey finds
More than 10% of children in Japan who developed acute brain syndrome after infection with COVID-19 have died, results of a nationwide survey recently announced by a health ministry research team has shown.
The survey identified 34 cases of acute encephalopathy associated with COVID-19 infection among those under 18 between January 2020 and May 2022. The team analyzed 31 patients who did not have any underlying illnesses that could be responsible for causing the brain disease.

Long COVID: 3 years in
March 11 marks 3 years since WHO declared COVID-19 to be a pandemic. While the world is determined to move on from the acute phase, at least 65 million people are estimated to struggle with long COVID, a debilitating post-infection multisystem condition with common symptoms of fatigue, shortness of breath, and cognitive dysfunction, impairing their ability to perform daily activities for several months or years. Although the majority of patients infected with SARS-CoV-2 recover within a few weeks, long COVID is estimated to occur in 10–20% of cases and affects people of all ages, including children, with most cases occurring in patients with mild acute illness. The consequence is widespread global harm to people’s health, wellbeing, and livelihoods—an estimated one in ten people who develop long COVID stop working, resulting in extensive economic losses.

Long COVID linked to lower brain oxygen levels, cognitive problems and psychiatric symptoms
Comments closedWe are the first to show reduced oxygen uptake in the brain during a cognitive task in the months following a symptomatic COVID-19 infection. This is important because a lack of sufficient oxygen supply is thought to be one of the mechanisms by which COVID-19 may cause cognitive impairment.

Long COVID stemmed from mild cases of COVID-19 in most people
Even mild COVID-19 cases can have major and long-lasting effects on people’s health. That is one of the key findings from our recent multicountry study on long COVID-19—or long COVID—recently published in the Journal of the American Medical Association.

Ten COVID Facts Health Officials Dangerously Downplay
Do not listen to powers that be who pretend that getting infected with COVID multiple times is now no big deal. They’re asking you to lower your guard for a nasty virus that can invade the brain, disregulate the immune system and damage the vascular system.
This strategy has led to predictable results — more direct deaths, more excess deaths, more disease and some 1.4 million Canadians reporting some form of long COVID over the last two years.

One of Long COVID’s Worst Symptoms Is Also Its Most Misunderstood
Brain fog isn’t like a hangover or depression. It’s a disorder of executive function that makes basic cognitive tasks absurdly hard.

El camino largo: Cuando los síntomas de la COVID-19 no desaparecen.
Although most people who have COVID-19 recover within a few weeks, some struggle with heart symptoms and problems such as brain fog, fatigue, headaches, dizziness, and difficulty breathing, even months after the initial infection goes away.

COVID-19 positive patients at higher risk of developing neurodegenerative disorders, new study shows
COVID-19 positive outpatients are at an increased risk of neurodegenerative disorders compared with individuals who tested negative for the virus, a new study presented today at the 8th European Academy of Neurology (EAN) Congress has shown.
The study, which analysed the health records of over half of the Danish population, found that those who had tested positive for COVID-19 were at an increased risk of Alzheimer’s disease, Parkinson’s disease, and ischaemic stroke.

Covid can shrink brain and damage its tissue, finds research
The first major study to compare brain scans of people before and after they catch Covid has revealed shrinkage and tissue damage in regions linked to smell and mental capacities months after subjects tested positive.
