How to use this library

Start with the symptom. Keep the differential honest.

  • This library does not tell you what you have. It shows what may belong in the workup.
  • A condition appears here when it can cause, mimic, amplify, or complicate psychiatric symptoms.
  • Testing should be targeted to the presentation, history, medications, sleep, and risk profile.
  • Urgent, sudden, severe, or unsafe symptoms belong in urgent care or emergency care.

Condition categories

Evidence labels

Not every claim has the same weight.

Established

Strong guideline, replicated review, or clear disease mechanism. Still interpreted in context.

Supported

Good evidence and clinical plausibility, but not definitive for every patient or setting.

Proposed

Framework-level reasoning or emerging mechanism. Useful for the differential, not proof.

Speculative

Too early for patient-facing action unless it is clearly labeled and bounded.
