Neurologic complications are one reported side effect of COVID-19. A study published in Brain in July looked at 43 patients with either confirmed, probable, or possible COVID-19 who also experienced brain-related complications, including stroke and encephalitis, which is inflammation of the brain. The researchers noted that the complications apparently weren't related to how severe the COVID-19 was, meaning that a milder case could still lead to debilitating side effects in the brain.
Some COVID-19 patients have also experienced a "brain fog," which includes constant fatigue and difficulty concentrating. This could be related to the virus itself or the immune system's response to it, and doctors say it may also be related to inflammation in the central nervous system.
