Have unexplained symptoms?

BioCog AI is in beta, providing diagnostic reports for patients with unexplained symptoms

Review the profile below - if it describes you, you're welcome to join.

Symptoms for 3+ months

Your symptoms have lasted at least three months and may be:

  • Progressive: getting worse over time.
  • Fluctuating: coming and going.
  • Persistent: staying the same.
"Atypical" or "non-specific" symptoms

Your symptoms don't fit neatly into one diagnosis or affect different parts of your body at the same time. If you've been told your presentation is "medically unexplained" or "functional", this applies to you.

For examples, see below.

Treatments haven't worked

Therapies you've tried haven't provided real relief:

  • Medications didn't work or helped only briefly.
  • Lifestyle changes haven't made a lasting difference.
With or without a diagnosis

You may or may not already have a diagnosis. Having another diagnosis does NOT exclude you. This includes no diagnosis yet, incomplete diagnosis, or one that doesn't fully explain your symptoms.

Common symptom patterns we investigate (examples only - other symptoms also qualify)
● Persistent fatigue, weakness, or "energy crashes".
● Diffuse muscle or joint pain.
● Neurological changes: tingling, numbness, dizziness.
● Flare-ups with stress, exertion, or temperature.
● GI issues: bloating, abdominal pain.
● Heart/autonomic symptoms: racing heart, BP swings.
Does this sound like you?
"Every test comes back normal, yet I've had
progressive symptoms for over a year."
"I've seen multiple doctors but I'm still struggling."
"I have fatigue and pain that don't fit any diagnosis."
"Treatments haven't worked and I suspect a
deeper cause."
Why This Research Matters

Millions of people live with persistent symptoms that remain unexplained. They see multiple specialists, undergo repeated blood tests, scans, and procedures, and still end up without a diagnosis or a clear path forward. This research study takes a different approach. Instead of comparing you to the "average patient", we look for what might be driving symptoms in your own biology. NIH research suggests that ~35% of difficult medical cases can be solved when combining a patient's DNA with detailed symptom and medical-history information. In this study, we collect your DNA (saliva sample), your complete medical record, and your symptom tracking. We then use our cutting-edge medical AI to analyse these data together and generate research hypotheses and potential mechanistic explanations for your underlying symptoms, specific to your unique biology.
