A new Centre for Addiction and Mental Health (CAMH) study found elevated levels of inflammation in the brains of patients who report persistent symptoms of long COVID.
Using advanced brain scanning with positron emission tomography (PET), the researchers found elevated levels of the protein TSPO, a brain marker of inflammation, in patients with onset of depression within several months after a COVID-19 infection.

Comments closedIn 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.
Comments closedA new study, published in the Journal of Alzheimer’s Disease Reports, has discovered that infection with SARS-CoV-2 (the virus that causes Covid) has a significant impact on cognitive function in patients with pre-existing dementia.
Comments closedMore 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.

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.
Comments closedComments 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.
More than half of patients with long Covid suffer from organ damage a year after the initial symptoms, new research suggests.
Even those who were not seriously ill when diagnosed with the virus report problems, with extreme difficulty breathing and cognitive impairment among the persistent symptoms.
The study, the results of which were published in the Journal of the Royal Society of Medicine, involved 536 people.
Six months after their initial diagnosis with coronavirus, the patients underwent an MRI scan which revealed ongoing health problems, with 62% of participants suffering from organ damage.
Comments closedEven 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.
Comments closedDo 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.
Comments closedBrain fog isn’t like a hangover or depression. It’s a disorder of executive function that makes basic cognitive tasks absurdly hard.
Comments closedAlthough 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.
Comments closedCOVID-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.
Comments closedSome people experience lingering cognitive decline, with degree of impairment linked to illness severity.
Comments closedThe 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.
