A common, confusing symptom

Brain fog isn't a medical diagnosis but it is a real experience: slowed thinking, mild forgetfulness and difficulty focusing.

Common contributors

  • Poor sleep quality (not just quantity).
  • Blood sugar swings.
  • Thyroid dysfunction.
  • Perimenopause and andropause.
  • Long-COVID and other post-viral states.

A practical first pass

  1. Track sleep and caffeine for two weeks.
  2. Eat protein with breakfast.
  3. Walk after lunch.
  4. Ask your clinician for a basic blood panel including thyroid.
