Sudden severe headaches require prompt medical evaluation. Investigations like CT scans are crucial for patients with headaches peaking within minutes and lasting over an hour to rule out subarachnoid hemorrhage.

Area of Science:

  • Neurology
  • Emergency Medicine

Background:

  • Acute onset headaches are a frequent clinical presentation.
  • While most headaches are benign, a subset indicate serious underlying pathology.

Purpose of the Study:

  • To identify historical features that necessitate further investigation for acute onset headaches.
  • To guide diagnostic workup for patients presenting with sudden severe headaches.

Main Methods:

  • Retrospective analysis of patient case histories presenting with acute headache.
  • Clinical correlation of headache characteristics with diagnostic findings.

Main Results:

  • Headache maximal immediately or within minutes, persisting over an hour, is a critical indicator.
  • This specific headache profile warrants neuroimaging and potentially lumbar puncture.

Conclusions:

  • Patient history is paramount in differentiating benign headaches from those requiring urgent investigation.
  • Exclusion of subarachnoid hemorrhage is essential for specific acute headache presentations.
