Can mild Covid affect the brain ?

Yes, according to an Oxford study.

The team investigated brain changes in 785 UK Biobank participants (aged 51–81).

The team compared Brain scans before COVID infection and Brain scans after infection.

They found that people with COVID subsequently had “brain shrinkage” and reduced “brain function” particularly relating to parts of brain dealing with emotions smell and long-term memory

It is not known whether these brain changes are temporary and reversible after a while or whether these changes are permanent.
