About This Assessment
Methodology
This assessment uses a weighted scoring algorithm across 5 fog types (inflammatory, hormonal, sleep-deprived, nutrient-deficiency, neurological) based on symptom patterns, timing, co-symptoms, and lifestyle factors. Free-text responses are analyzed for keyword matches that adjust scores.
Limitations
This is an educational tool, not a diagnostic instrument. Brain fog has many overlapping causes and most people have 2-4 contributing factors. Results should inform — not replace — professional medical evaluation.
