Diagnosing headaches involves a patient interview and physical exam to determine if the cause is primary, benign secondary, or life-threatening. This initial assessment guides further investigation and treatment for all headache types.
Area of Science:
- Neurology
- Emergency Medicine
- Diagnostic Medicine
Background:
- Headache diagnosis in acute settings requires differentiating primary, benign secondary, and life-threatening secondary causes.
- Potentially life-threatening causes include subarachnoid hemorrhage, bacterial meningitis, and intracranial hypertension.
Purpose of the Study:
- To outline the diagnostic approach for acute headaches.
- To emphasize the importance of patient interview and physical examination in guiding investigations and treatment.
- To categorize headaches for appropriate management strategies.
Main Methods:
- Clinical interview with the patient.
- Thorough physical examination.
- Classification of headaches into four groups based on onset and duration.
Main Results:
- The cornerstone of diagnosis is the patient interview and physical exam.
- These steps determine the need for investigations (inpatient or outpatient) and treatment.
- Headaches with recent onset or unusual/worrisome features require investigation for secondary causes.
Conclusions:
- Early and accurate diagnosis is crucial for appropriate management of acute headaches.
- A systematic approach involving patient history and physical examination is essential.
- Distinguishing primary from secondary headaches, especially dangerous ones, is paramount.
