Headaches are the most common neurological complaint we see — and the vast majority are benign tension headaches or migraines. But every neurologist knows that buried among the everyday headaches are a small number that represent medical emergencies. Knowing the difference matters enormously.
The "SNOOP" Red Flags for Dangerous Headache
Neurologists use the SNOOP framework to identify headaches that require urgent investigation:
S — Systemic Symptoms
Headache accompanied by fever, weight loss, night sweats, or rash. Can indicate meningitis, encephalitis, or systemic infection.
N — Neurological Signs
Confusion, weakness on one side of the body, slurred speech, vision disturbance, or difficulty walking alongside a headache. These suggest stroke or intracranial bleed.
O — Onset: Sudden and Severe ("Thunderclap")
A headache that reaches its peak intensity within seconds to a minute. This is the classic presentation of subarachnoid haemorrhage until proven otherwise.
O — Onset After Age 50 (New headache)
A new type of headache in someone over 50 raises concern for giant cell arteritis, which can cause permanent vision loss if untreated.
P — Progressive or Positional
Headaches worsening over weeks, or worse lying down or bending forward. May indicate raised intracranial pressure or a growing mass.
Go to Emergency Right Now If Your Headache Is:
- 🚨"The worst headache of my life" — must be evaluated for subarachnoid haemorrhage immediately
- 🚨Thunderclap onset — maximal pain within 60 seconds of starting
- 🚨Headache + fever + stiff neck — classic triad of bacterial meningitis
- 🚨Headache + focal neurological symptoms — weakness, speech difficulty, confusion, vision loss
- 🚨Headache after head injury — particularly if worsening after initial improvement
- 🚨Headache in a person with cancer or HIV — risk of brain metastasis or opportunistic infection
What About Regular Headaches?
Tension headaches and migraines, while often debilitating, are not medical emergencies in most cases. Signs that your headache is likely benign:
- Similar to headaches you've had before
- Gradual onset over 30+ minutes
- Responds (even partially) to paracetamol or ibuprofen
- No neurological symptoms
- Triggered by stress, poor sleep, or dehydration
- Improves with rest in a dark, quiet room
Headaches That Should Prompt a Scheduled Neurology Appointment
- Headaches more than 15 days per month (chronic daily headache)
- Frequent painkiller use for headache (medication overuse headache)
- Headaches waking you from sleep
- A new headache pattern different from your usual
- Aura symptoms (visual zigzag lines, tingling) without a history of migraine
When in Doubt, Get Checked
The most important rule with headaches: if this headache is different from any you've had before — in quality, severity, or associated symptoms — seek medical attention the same day. The stakes are too high to wait and see.
