Neurologic Events After COVID-19 Vaccines Assessed
All patients hospitalized with new or relapsing neurologic events after SARS-CoV-2 vaccination at a New York tertiary hospital had one or more risk factors for their neurologic condition, a prospective study showed. The most prominent neurologic index events in these vaccinated patients were ischemic stroke (37.7%), encephalopathy (32.6%), seizure (15.9%), and intracranial hemorrhage (ICH; 9.4%), […]
Herpes Viruses Linked to Brain Changes
Symptomatic herpes viruses were linked with several neurologic and cognitive features, but not with Alzheimer’s disease processes, a longitudinal cohort study showed. Among older adults who mainly were cognitively normal, herpes virus infection was associated with accelerated tissue loss in brain white matter over time, particularly in the temporal lobe, according to Keenan Walker, PhD, […]
Post-COVID Neurologic, Psychiatric Symptoms May Persist for 2 Years
Up to 2 years after infection, people who had COVID-19 continued to face increased risks of neurologic and psychiatric sequelae compared with people who had other respiratory infections, a retrospective study showed. Health records of nearly 1.3 million people — mostly in the U.S. — showed that risks of cognitive deficit (brain fog), dementia, psychotic […]
Bell’s Palsy, Other Rare Events Not Linked With COVID-19 Vaccines
Immune-mediated neurologic events did not increase after COVID-19 vaccination, electronic health record data in the U.K. and Spain showed. No safety signal was found between COVID-19 vaccines and Bell’s palsy, encephalomyelitis, Guillain-Barré syndrome, or transverse myelitis, reported Daniel Prieto-Alhambra, MD, PhD, of the University of Oxford in England, and co-authors. However, rates of Bell’s palsy, […]
