Acute Headache Differential Tree

Acute headache differential diagnosis tree

An acute headache differential diagnosis tree helps learners order their questions around urgency. Red flags such as sudden onset, neurological change and signs of infection are separated before common primary headache patterns. The final leaves are prompts for assessment, not conclusions. Use the tree to prepare a case presentation or revise clinical reasoning, then adapt it to the patient context, examination and local guidelines. Do not use a diagram alone to decide whether someone needs urgent medical care.

FAQ

Questions fréquentes

Why do red flags appear first?

They identify presentations that may need urgent assessment before considering common primary headaches.

Does migraine exclude other causes?

No. A migraine-like pattern still needs clinical context and red-flag assessment.

Can this be used for patients?

It is for education and case discussion, not self-diagnosis or treatment decisions.
