People experiencing long COVID's brain fog may struggle to focus and remember things. This can impact daily life and work.

Dopamine is a neurotransmitter that plays a key role in regulating motivation, pleasure, and memory. Research suggests that COVID-19 can lead to inflammation in the brain, which may disrupt dopamine production and cause fatigue, brain fog, and other symptoms.

A recent case study found a link between long COVID and vestibular symptoms, and another study discovered that brain blood flow is linked to fatigue after COVID-19.
