SARS-CoV-2 virus found to migrate within neurons and infect the brain

The emergence of different variants of SARS-CoV-2 has produced a wide range of clinical profiles and symptoms in patients. For the first time, researchers at the Institut Pasteur and Université Paris Cité have demonstrated, in an animal model, a characteristic common to several SARS-CoV-2 variants: the ability to infect the central nervous system.

Long Covid: MRI scans reveal new clues to symptoms

People living with long Covid after being admitted to hospital are more likely to show some damage to major organs, according to a new study.

MRI scans revealed patients were three times more likely to have some abnormalities in multiple organs such as the lungs, brain and kidneys.

High levels of 2 blood-clotting proteins may portend post-COVID brain fog

High levels of two blood biomarkers during infection could predict cognitive dysfunction, or “brain fog,” among COVID-19 survivors 6 and 12 months after hospitalization, according to a UK study published yesterday in Nature Medicine.

Blood Clotting Proteins Might Help Predict Long COVID Brain Fog

Many people who have long COVID—a condition in which health issues persist months after infection—report struggling with “brain fog,” recurring memory and concentration lapses that make it difficult­­ to function in everyday life. Now a new study has found these cognitive problems could result from blood clots triggered by infection, possibly through mechanisms like those that cause some types of dementia. These clots leave telltale protein signatures in blood, suggesting that testing for them could help predict, diagnose and possibly even treat long COVID.

Μακρά Covid-19: Οι θρόμβοι αίματος μπορεί να ευθύνονται για την εγκεφαλική ομίχλη

Blood clots in the brain or lungs may be responsible for certain symptoms of long COVID, including brain fog and fatigue, according to a new British study.

Halifax researcher seeks COVID-19 long haulers to study effects of virus on brain

Dr. Carlos Hernandez is an assistant professor in Dalhousie University’s faculty of computer science. He hopes to contribute to long COVID research in collaboration with scientists at Western University in London, Ont., and the National Autonomous University of Mexico in Mexico City in a multi-year study assessing cognitive damage caused by the condition.

But there’s just one issue: He needs more participants in the Halifax area.

Long COVID still worrisome 2 years after infection

Our findings highlight the substantial cumulative burden of health loss due to long COVID and emphasize the ongoing need for health care for those faced with long COVID. It appears that the effects of long COVID for many will not only impact such patients and their quality of life, but potentially will contribute to a decline in life expectancy and also may impact labor participation, economic productivity, and societal well-being.

Long Covid symptoms create a greater burden of disability than heart disease or cancer, new study shows

People who survived Covid-19 early in the pandemic, before there were vaccines, continued to be at higher risk for a slew of health problems for up to two years after they got over their initial infections, compared to others who didn’t test positive, a new study finds, and that was especially true if they were hospitalized.

These health problems include heart problems, blood clots, diabetes, neurologic complications, fatigue and difficulties with mental health and have come to be known collectively as long Covid.

Many long-covid symptoms linger even after two years, new study shows

People who endured even mild cases of covid-19 are at heightened risk two years later for lung problems, fatigue, diabetes and certain other health problems typical of long covid, according to a new study that casts fresh light on the virus’s true toll.

The analysis, published Monday in the journal Nature Medicine, is believed to be the first to document the extent to which an array of aftereffects that patients can develop — as part of the diffuse and sometimes debilitating syndrome known as long covid — linger beyond the initial months or year after they survived a coronavirus infection.

Long COVID Is Disabling Kids. Why We Ignore It

Yet we may have disastrously underestimated one of the most serious sequelae: infection of the brain and nervous system. And we may have missed the neurological damage done to children and young adults who seem to have recovered from COVID-19.

Scientists Are Just Beginning to Understand COVID-19’s Effect On the Brain

Time

July 17, 2023

The list of neurocognitive issues that Meropol’s team and other researchers must track is extensive: cognitive decline, changes in brain size and structure, depression and suicidal thinking, tremors, seizures, memory loss, and new or worsened dementia have all been linked to previous SARS-CoV-2 infections. In some cases, these longer-term problems occur even in patients with relatively mild COVID-19.

New imaging technique captures COVID-19’s impact on the brain

Some may think COVID-19 affects just the lungs. What was found is that this new MRI technique that we created is very good at identifying changes to the brain due to COVID-19. COVID-19 changes the white matter in the brain.

Researchers discover that COVID-19 can cause brain cells to fuse

Researchers at The University of Queensland have discovered that SARS-CoV-2 and other viruses can cause brain cells to fuse, initiating malfunctions that lead to chronic neurological symptoms.

Could fused neurons explain COVID-19’s ‘brain fog’?

Researchers have demonstrated that a SARS-CoV-2 infection can induce brain cells to fuse together, with severe impacts on the functioning of neurons. Neurons may fuse together with other neurons or glia, and larger multicellular syncytia may be formed. The fusion of neurons may be one of the causes of the cognitive issues associated with COVID-19.

CAMH study confirms ongoing brain inflammation associated with long COVID

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.
