What is brain fog?
Brain fog is not a diagnosis; it is a description. People report trouble focusing, finding words, holding information in mind, and making decisions.
Key things to know
Common causes include sleep deprivation, chronic stress, depression, anxiety, burnout, and some medical conditions such as thyroid problems, anaemia, and long COVID.
- A description, not a diagnosis: slowed thinking, poor focus, forgetfulness.
- Common causes: poor sleep, chronic stress, depression, anxiety, burnout.
- Medical causes exist too: thyroid problems, anaemia, long COVID.

What helps
Persistent brain fog deserves attention rather than pushing through. Address sleep and stress first; if it continues, a medical checkup and mental health assessment can identify the cause.
