Brain fog can make a person feel as if the processes of thinking, understanding, and remembering are not working as they should.
Different brain functions can be affected by brain fog, including:
- memory, which allows information to be stored and recalled
- the ability to use and understand language
- information processing, which aids understanding and focus
- visual and spatial skills used in drawing, recognizing shapes, and navigating space
- calculation abilities
- executive functioning abilities used for organization, problem-solving, and planning
If one or more of these functions is impaired, someone may have difficulty understanding, find it hard to focus or concentrate, forget things, and experience mental fatigue.
