  • Intracranial bleed (esp. SAH)

other serious secondary has
Other Serious Secondary HAs

What are the “red flags” which suggest a serious headache?
  • Thunderclap headache: SAH, vascular dissection, venous thrombosis, pituitary apoplexy.
  • Headache onset during exertion: SAH or dissection
  • HIV and Immunosuppression: infections and tumors
red flags cont d
“Red Flags” (cont’d)
  • New onset headache over age 50: mass lesions and temporal arteritis
