🧠 Sudden “Worst Headache of Life” — SAH

✅ Answer: (B) SAH — Subarachnoid hemorrhage

📖 What is SAH?

SAH stands for subarachnoid hemorrhage, a type of intracranial bleeding in which blood enters the subarachnoid space surrounding the brain.

A classic presentation is a sudden, severe headache that reaches maximum intensity very rapidly and is often described by patients as the “worst headache of my life.”

⚠️ Why is SAH the Most Concerning?

The sudden onset and extreme severity are important warning signs of an acute intracranial event. SAH can rapidly lead to serious complications such as increased intracranial pressure, decreased consciousness, seizures, cerebral vasospasm, and neurological deficits.

The headache may occur with other symptoms such as:

• 🤮 Nausea and vomiting
• 💡 Photophobia
• 🧠 Neck stiffness
• 😵 Altered level of consciousness
• ⚡ Seizures

👉 A sudden “thunderclap” headache should therefore be treated as an emergency until a dangerous cause such as SAH is excluded.

❌ Why Are the Other Options Wrong?

A. Migraine
❌ Migraine can cause severe headache and may be associated with nausea and photophobia, but a sudden thunderclap headache reaching peak intensity immediately is a major red flag for SAH.

B. SAH
✅ Correct. Sudden, severe “worst headache of life” is a classic presentation of subarachnoid hemorrhage.

C. Tension headache
❌ Usually causes a mild-to-moderate, pressing or tightening headache rather than an abrupt, explosive headache.

D. Sinusitis
❌ Sinusitis may cause facial pressure, congestion, and headache, but it does not typically cause a sudden thunderclap headache.

📝 Quick Comparison

📌 Exam Tip: The phrase “worst headache of life” is a classic high-yield clue for subarachnoid hemorrhage, particularly when the headache has a sudden thunderclap onset.
