Brain fog is not a medical term but used to describe a range of symptoms including:
- poor concentration
- feeling confused
- thinking more slowly than usual
- fuzzy thoughts
- lost words
- mental fatigue
Brain fog can feel similar to the effects of sleep deprivation or stress. It's not the same as dementia and does not mean structural damage to the brain.
People usually recover from brain fog. You may get similar symptoms after other infections, a minor head injury or during the menopause. Brain fog is also common if you have depression, anxiety or stress.
While recovering from coronavirus (COVID-19), some people experience brain fog. Symptoms may vary and change over time. It's not just people who were hospitalised with coronavirus who can develop brain fog. It's a common part of long COVID.
Anxiety, low mood and fatigue all play a role in affecting how your brain functions.
