COVID-19 can spark a severe immune response in the central nervous system, affecting immune cells in the vascular system and brain.
Combining artificial intelligence technology with data sets related to both Alzheimer's and COVID-19, researchers were able to identify a mechanism by which coronavirus can lead to Alzheimer's-like symptoms. The findings add to the growing body of evidence that COVID-19 infection can have lasting effects on brain function.
Neurological and psychological symptoms associated with COVID-19 infection, such as fatigue and depression, are more common in those with mild coronavirus infection than previously believed.
Two medications commonly used to treat inflammation and HIV infection have been repurposed in the fight against COVID-19. Researchers found combined cepharanthine/nelfinavir therapy can hasten the clearance of coronavirus infection from a person's lungs in as little as 4.9 days. Cepharanthine hindered the entry of SARS_CoV_2 into cells, preventing the virus from binding to a protein on the cell membrane it uses as a gateway. Nelfinavir prevented the virus from replicating inside cells by inhibiting a protein the virus relies on for replication.
Gray matter was reduced in areas of the frontal gyri of patients with COVID-19. Significant gray matter reductions were seen in those who received oxygen therapy and in those who reported fever. The findings suggest coronavirus affects the frontotemporal brain network due to reduced oxygen and fever.
Neurological symptoms associated with COVID-19, from losing the sense of smell to stroke, are linked to a six-fold higher risk of dying as a result of coronavirus.
Researchers have identified acute transverse myelitis (ATM) in a number of COVID-19 patients. ATM, which is marked by inflammation of the spinal cord, is a rare neurological disorder that can lead to spinal cord lesions, paralysis, and bowel dysfunction.
COVID-19 may not directly infect the brain, but the virus is still capable of causing significant neurological damage, a new study reports. Researchers say the neurological changes seen as a result of coronavirus infection are likely related to inflammation triggered by viral infection in different parts of the body or the brain's blood vessels.
A number of videos have surfaced on popular channels showing people experiencing some adverse effects following the coronavirus vaccine. Researchers say some of the cases could be related to functional neurological disorder, a common neuropsychological condition.
The COVID-19 pandemic has had a significant impact on stress in both pregnant and postpartum women. Researchers say this is concerning as prenatal stress can hamper fetal brain development.
Constant exposure to images of syringes and people getting the COVID-19 vaccine on TV and social media may discourage those with phobias of needles from getting their shots, researchers report.
