RSS

Delirium is a mental state in which a person is confused, disoriented, and not able to think or remember clearly. The person may also be agitated and have hallucinations, and extreme excitement.

Can transgenic mice studies illuminate neurological complications associated with SARS-CoV-2 in humans?

The potentially deadly COVID-19 has not affected animals with corresponding severity. To understand the mechanism of severe disease, animal models have been used. This includes a mouse model that expresses human angiotensin-converting enzyme 2 (hACE2) under the cytokeratin 18 promoter (K18-hACE2). A new study indicates that this may not be a faithful model of human lethal infection with SARS-CoV-2.

Study shows how neurons can become a target of SARS-CoV-2 infection

Using both mouse and human brain tissue, researchers at Yale School of Medicine have discovered that SARS-CoV-2 can directly infect the central nervous system and have begun to unravel some of the virus's effects on brain cells.

COVID-19 ICU patients found to have higher burden of delirium and coma

COVID-19 patients admitted to intensive care in the early months of the pandemic were subject to a significantly higher burden of delirium and coma than is typically found in patients with acute respiratory failure.

Brain damage is not caused by direct COVID-19 attack, indicates study

n an in-depth study of how COVID-19 affects a patient's brain, National Institutes of Health researchers consistently spotted hallmarks of damage caused by thinning and leaky brain blood vessels in tissue samples from patients who died shortly after contracting the disease.

Change in mental status or falls may be misinterpreted as infection in nursing homes

There is a widespread belief that a change in the mental status or an increase in falls in a nursing home resident may indicate an underlying infection.

D614/G614 variants of SARS-CoV-2 affect neuronal transmission; G614 better at membrane fusion

The COVID-19 pandemic is showing a strong comeback after an initial reduction in the number of cases, following energetic public health interventions.

Can melatonin help prevent severe COVID-19?

A team of researchers at the University of Toronto in Canada has found that melatonin can be an adjuvant to augment the efficacy of anti-SARS-CoV-2 vaccines. They believe that the drug is a potential “silver bullet” to combat the COVID-19 pandemic.

Study investigates best practices for mechanical ventilation in people with acute respiratory failure

It's a decision being made thousands of times over inside hospitals all around the country: is it time to place a patient struggling to breathe on a ventilator?

Delirium common after hospital discharge in critically ill COVID-19 patients

Anesthesiologist and other researchers from Michigan Medicine, Ann Arbor, New York Medical College, Valhalla and Center for Consciousness Science, University of Michigan Medical School, Ann Arbor, have reported a case series of critically ill coronavirus disease 2019 (COVID-19) patients who have developed neuropsychological symptoms after having been discharged from the hospital.

Delirium accompanied by fever could be an early symptom of COVID-19

Delirium accompanied by fever could bean early symptom of COVID-19. This is the main conclusion drawn by a scientific research review carried out by researchers from the Universitat Oberta de Catalunya.

New model could help identify people at risk for long COVID

Researchers in the UK, United States, and Sweden have presented new findings that could help identify individuals at risk of "long COVID" – a protracted course of coronavirus disease 2019 (COVID-19) symptoms last for more than 28 days.

COVID-19 patient's immune response may underlie the effects on the nervous system

It is probably the immune response to, rather than the virus in itself, that causes sudden confusion and other symptoms from the nervous system in some patients with COVID-19. This is shown by a study of cases involving six Swedish patients, now published in the journal Neurology.
