The patient reporting the worst headache of my life may be suffering from which condition?

• A. Migraine with aura.
• B. Tension-type headache.
• C. Sinus headache.
• D. Hemorrhagic stroke or subdural bleed.

Answer: (D)

A sudden, thunderclap headache described as the worst headache of life is a red flag for intracranial bleeding. The scenario most strongly points to a hemorrhagic event in the brain, such as a subarachnoid hemorrhage from a ruptured aneurysm, and it can also occur with other bleeding such as intracerebral hemorrhage or subdural hematoma. These conditions can progress rapidly and are life-threatening, so urgent assessment and neuroimaging are essential.

Migraine with aura, tension-type headaches, and sinus headaches typically do not present with this abrupt, maximal onset and are far less likely to indicate a brain bleed. They tend to have a more gradual onset or a characteristic pattern and symptoms (nausea, photophobia for migraines; band-like pressure for tension headaches; facial pressure and nasal symptoms for sinus headaches) that differ from a thunderclap headache.

In practice, treat this as a medical emergency: ensure airway and circulation, monitor vitals, and arrange rapid transport for imaging (non-contrast head CT) to rule out hemorrhage. If imaging is negative but suspicion remains high, further evaluation may be needed.
