Brain Fog Scale

Find out whether you exhibit brain fog by taking this short self-assessment.

Does it ever feel like you are moving through a thick mental haze where simple thoughts feel out of reach? This sensation, sometimes called "brain fog," isn't just a sign of being tired—it is a complex cognitive state where focus drifts and mental fatigue takes over. Much like our Insomnia Severity Index, this assessment looks at how physical and mental exhaustion can intersect to cloud your daily functioning.

The Brain Fog Test is designed to help you identify specific areas where your thinking might be slowing down, from memory recall to verbal fluency. While everyone experiences occasional forgetfulness, a persistent feeling of being "detached" or "unfocused" can stem from various lifestyle factors such as high stress or poor nutrition. If you often find yourself ruminating on these mental lapses, you may also find our Mistake Rumination Scale helpful in understanding your mental patterns.
