Researchers tested undergrads while measuring brain blood flows. Their brain scans looked like people in their 60s: previously infected students exhibited distinct prefrontal haemodynamic patterns during cognitive engagement, reminiscent of those observed in adults four decades older, and this appeared to be especially true if they reported experiencing brain fog due to COVID-19. Over a third of them showed objective cognitive impairment: 37.33 % of participants who reported previously having COVID-19 displayed objective cognitive impairment [...] (assessed via computerised testing), And neuron death is irreversible: This may indicate microglial hyperactivation, theoretically driven by elevated oxidative stress from dysfunctional mitochondria—a possible contributor to cell death and cognitive impairment https://www.sciencedirect.com/science/article/pii/S0889159124007311 h/t @PatrickWirth@mstdn.ca #COVID #SARSCoV2 #LongCOVID #COVID19 #BrainFog #PASC

@datum@zeroes.ca @PatrickWirth@mstdn.ca haven’t we proven that neuron death is not in fact irreversible? I know the scientific establishment used to believe that,but it seems to be pretty widely accepted now that adults can grow new brian cells.

@datum@zeroes.ca @PatrickWirth@mstdn.ca "To date, 770 million people worldwide have contracted COVID-19" It is many more. The PIENTER study in the Netherlands tested for antibodies from the nucleus of the virus. Virtually everyone had in the infection in the Netherlands (less than 1% not) by the end of 2023. The Chinese CDC reported that 80% of the population got infected in their exit wave. One can assume that more than 95% of the world's population has had Covid at least once.
