Diagnosing most headaches relies on a thorough patient history and physical exam. However, specific indications warrant diagnostic testing to rule out serious, life-threatening conditions like brain tumors or subarachnoid hemorrhage.

Area of Science:

  • Neurology
  • Diagnostic Medicine

Background:

  • Most headaches are diagnosed clinically through patient history and physical examination.
  • Diagnostic testing is not routinely required for initial headache assessment.

Purpose of the Study:

  • To emphasize the importance of clinical evaluation in diagnosing headaches.
  • To identify specific indications for diagnostic testing in headache patients.

Main Methods:

  • Review of clinical guidelines and diagnostic algorithms for headache management.
  • Analysis of potential diagnostic yield and risks of undertesting.

Main Results:

  • A comprehensive headache history and physical examination are sufficient for diagnosing the majority of headaches.

  • Diagnostic testing may be indicated in a subset of patients with normal physical exams, despite a potentially low yield.
  • Failure to perform indicated testing can lead to misdiagnosis of serious conditions.

    • Conclusions:

    • Clinical assessment remains the cornerstone of headache diagnosis.
    • Judicious use of diagnostic testing is crucial when specific red flags are present.
    • Timely diagnostic testing can prevent misdiagnosis of severe intracranial pathologies.
