[quote=Anonymous]Covid infections - Most are on their 3rd, 4th, 5th infection by now Study shows even mild SARS-CoV-2 infections cause changes in EEG signatures that indicate cognitive decline, also in children and adolescents. https://bmcmedicine.biomedcentral.com/articles/10.1186/s12916-024-03481-1 COVID-19 Leaves Its Mark on the Brain. Significant Drops in IQ Scores Are Noted https://www.scientificamerican.com/article/covid-19-leaves-its-mark-on-the-brain-significant-drops-in-iq-scores-are/ February 2024 study in the New England Journal of Medicine that shows that every infection impacts the brain - Very large study that followed 800,000 people over three years. Link to study: https://www.nejm.org/doi/full/10.1056/NEJMoa2311330 Covid-19 can cause brain cells to fuse https://news.uq.edu.au/2023-06-08-covid-19-can-cause-brain-cells-fuse A study from Taiwan shows that in children ages 6 to 18 years, COVID infection can lead to changes in the brain that are associated with persistent headaches, memory, and attention problems. MRI scans of the brain showed enlarged gray matter volumes in children with severe symptoms, correlating with visual perception deficits and neuropsychiatric complaints. The severity of neuropsychiatric symptoms during the acute phase may serve as a predictive factor for the severity and brain volume differences of chronic phase. https://www.sciencedirect.com/science/article/pii/S0887899425002541[/quote]
