What this brain fog measures
This brain fog quiz estimates self-reported brain fog symptom frequency signals patterns across four domains. Twenty-two original frequency items group into cloudy focus, slow recall, word gaps, mental fatigue. Each item also maps to a fear-of-intimacy stack layer. A second results chart inspired by FOIS-style intimacy avoidance themes from Descutner and Thelen (1991), adapted to this topic. Your brain fog symptom index averages these patterns into a 0 to 100 score where higher numbers mean more endorsed brain fog symptom frequency signals on this screener, not a clinical diagnosis.

|---|---|---|
| Lower Brain Fog Symptoms | 0 to 35 | Fewer endorsed brain fog symptom frequency signals patterns; situational stress can still raise scores briefly |
| Mixed Brain Fog Symptoms | 36 to 65 | Blend of occasional and recurring brain fog symptom frequency signals signals worth tracking with a clinician if persistent |
| Higher Brain Fog Symptoms | 66 to 100 | Frequent brain fog symptom frequency signals signals; schedule professional evaluation, not self-diagnosis |
