DIY Health connects four pieces so you can investigate brain fog without guessing alone.

1. NOTICE

   Find your type

   A short intake scores eight mechanism axes and names the most likely drivers of your fog. A pattern, not a diagnosis.

2. ASK

   Read the cards

   Every treatment card shows an evidence estimate (share who report it helped), a crowd forecast, and a tested result when an Open Test has run.

3. TEST

   Try one thing

   Run a personal Hypothesis Test or join an Open Test. Check in daily. Get an honest verdict from your own numbers.

4. LEARN

   Keep a record

   Ruled-out lists, reviews, and your type live in Your Investigations. Bring them to your doctor when you want a second set of eyes.
