Start with what changed
Onset, timing, medicines, illness, sleep, meals, pain and other changes often give you a better starting point than a giant symptom checklist.
ABOUT WBF
How What Is Brain Fog works.
Brain fog is a vague name for a real problem. WBF helps you see when the problem began and what changed around that time.
Why it exists
Paul noticed changes in his thinking, motivation and ability to work.
Paul spent years seeing doctors, reading papers, running experiments and following wrong turns. He turned what he learned into a larger project so other people would not have to begin from zero.
Read Paul’s story →What we do
We help readers organize what changed, compare possible contributors and prepare questions for a clinician.
Compare possibilities without claiming a diagnosis
A familiar symptom isn't a diagnosis. Useful pages show the evidence for a link, its important limits and other conditions that can look similar.
Make tests answer a question
A blood test, sleep study or home measurement is useful only when it addresses a specific question. A normal result may rule out one explanation without ruling out the others.
Show the source trail
Readers should be able to open the sources behind a medical claim instead of taking the site’s word for it.
Who is behind it
Founder, editorial work and medical review have different jobs.
Founder
Paul Coskun
The founder story explains why WBF exists and the long personal investigation behind it. It's context, not clinical authority.
Founder story →Editorial desk
Research, writing and product work
Literature review, source collation, page structure, cross-page consistency, copy editing and the engineering that turns information into usable tools.
Editorial policy →Medical review
Dr. Amarfei
Medical review checks whether clinical explanations, rule-out advice and treatment language are accurate and appropriately cautious.
Medical review →Funding
How we fund this
The funding page explains how we fund WBF and which future changes we'd have to disclose.
How we fund this →The trust boundary
A personal origin story does not get to overrule the evidence.
Paul’s experience can explain why a question matters. It cannot prove a mechanism, diagnose a reader or
establish that something which helped him will help somebody else. Medical claims need their own evidence,
citations and review.
Where evidence is weak or mixed, the useful answer may be that the link isn't established. WBF is more useful when it tells you that plainly than when it tries to make every page sound equally certain.
What this is not
WBF cannot diagnose you or promise a cure.
WBF provides educational information and tools that help you organize your own observations. It is not a replacement for professional medical advice, diagnosis or treatment. A page can help you understand a possibility and prepare better questions; it cannot settle a complex medical problem from one screen.
Get medical help for sudden confusion, new weakness, speech or vision changes, a seizure, a severe new headache or other sudden brain or nerve changes. The library can wait.
