"Long-term persistent symptoms of COVID-19 affect 30–80% of patients who have recovered from the disease and may continue for a long time after the disease has been overcome. The duration of these symptoms over time might have consequences that affect different aspects of health, such as cognitive abilities. The main objective of this systematic review and meta-analysis was to objectify the persistent COVID-19 cognitive deficits after acute phase of infection and to summarize the existing evidence. Additionally, we aimed to provide a comprehensive overview to further understand and address the consequences of this disease.

Thanks, very interesting. Despite all the caveats, it's clear there's a problem.
I should think that some effects ease over time, but not when they result from the physical brain damage that severe Covid can do.
