A paper published in Nature looked at brain autopsies of people that died from COVID-19. Brain endothelial cells were found to be infected and there was an increase in string vessels (lost capillaries).
This helps to explain how brain damage happens and relates it to the 76% of patients who may have impairment and a range of psychiatric symptoms.

65 Million People Have Long COVID
A meta study found that 65 million people around the world have Long COVID. The chances of developing long COVID is 10-30% of non-hospitalized cases, 50-70% of hospitalized cases, and 10-12% of vaccinated cases. A significant number of people with long COVID are unable to return to work which contributes to labor shortages.
