Is there any estimate how long the fog lasts after covid? i'm pretty sure i had it on fathers day and since then the fatigue and mental fog has been debilitating. any chance anyone knows how long this lasts?

COVID 19: Cognitive problems are more likely to occur with severe disease. One study revealed that 65% of ICU patients experienced delerium. The duration of mental fog depends to a large extent on the severity of illness & what parts of the body were damaged. I have included an article that helps to address this: https://medicalxpress.com/news/2020-08-covid-memory-loss-cognitive-decline.html
