Headache: Migraine vs Cluster vs Tension — MRCP Part 1

TL;DR:

 Distinguishing migraine, cluster headache, and tension-type headache is a core topic in MRCP Part 1, where questions focus on symptom patterns, duration, and treatment. Migraine typically presents with unilateral throbbing pain and nausea, cluster headache causes severe unilateral orbital pain with autonomic features, and tension headache produces bilateral pressing discomfort without nausea. Recognising these classic patterns allows rapid and accurate exam answers.

Why this matters

Primary headache disorders are frequently tested in MRCP neurology questions. Candidates are expected to differentiate migraine, cluster headache, and tension-type headache using clinical descriptions rather than investigations.

MRCP questions commonly ask:

• The most likely diagnosis

• The distinguishing clinical feature

• The most appropriate acute treatment

• The most appropriate preventive therapy

Understanding these headache syndromes helps secure reliable marks in neurology sections of the exam. Review the full syllabus in the MRCP Part 1 overview:

The Three Major Primary Headaches

MRCP questions typically describe headaches using symptom clusters. Recognition of these patterns is essential.

Key Differences

Feature	Migraine	Cluster Headache	Tension Headache
Pain quality	Throbbing	Severe boring	Tight band-like
Laterality	Usually unilateral	Strictly unilateral	Bilateral
Severity	Moderate–severe	Very severe	Mild–moderate
Duration	4–72 hours	15–180 minutes	30 min–several days
Autonomic features	Rare	Prominent	Absent
Nausea	Common	Rare	Absent
Photophobia	Common	Possible	Rare
Behaviour	Prefers rest	Restless	Normal activity
Acute treatment	Triptans	Oxygen	Simple analgesia
Prevention	Propranolol	Verapamil	Amitriptyline

High-yield exam point:Cluster headache is the only primary headache classically associated with prominent autonomic symptoms such as lacrimation and nasal congestion.

The Five Most Tested Subtopics

1. Migraine Diagnostic Features

Migraine is one of the most frequently tested headache disorders in MRCP.

Typical features include:

• Unilateral throbbing pain

• Moderate or severe intensity

• Worsened by activity

• Nausea or vomiting

• Photophobia or phonophobia

• Duration 4–72 hours

Migraine aura may include:

• Zigzag visual lines

• Scintillating scotoma

• Sensory symptoms

• Speech disturbance

According to the International Classification of Headache Disorders:

https://ichd-3.org/

High-yield fact: Migraine aura typically lasts 5–60 minutes, a classic MRCP testing point.

2. Migraine Treatment

MRCP questions frequently test drug selection.

Acute treatment:

• NSAIDs

• Paracetamol

• Triptans

• Antiemetics

Preventive therapy:

• Propranolol

• Topiramate

• Amitriptyline

• Candesartan

NICE headache guidelines summarise recommended treatments:

https://www.nice.org.uk/guidance/cg150

Classic MRCP point: Triptans are contraindicated in ischaemic heart disease.

3. Cluster Headache Recognition

Cluster headache is highly distinctive in MRCP vignettes.

Typical presentation:

• Middle-aged man

• Severe unilateral orbital pain

• Attacks often occur at night

• Episodes last 30–90 minutes

• Repeated attacks for weeks

Associated autonomic features:

• Lacrimation

• Conjunctival injection

• Nasal congestion

• Rhinorrhoea

• Ptosis or miosis

Exam pearl: Patients with cluster headache are typically agitated or restless, unlike migraine sufferers who prefer to lie still.

4. Cluster Headache Treatment

Treatment is a classic MRCP topic.

Acute therapy:

• High-flow oxygen

• Subcutaneous sumatriptan

Preventive therapy:

• Verapamil (first-line)

NICE recommendations for cluster headache management:

https://cks.nice.org.uk/topics/headache-cluster/

High-yield point: High-flow oxygen is the most characteristic MRCP answer for acute cluster headache.

5. Tension-Type Headache Features

Tension-type headache is usually diagnosed by exclusion in exam questions.

Typical features:

• Bilateral pain

• Pressing or tightening sensation

• Mild to moderate intensity

• No nausea

• No vomiting

• Normal activity possible

Duration:

• 30 minutes to several days

Clinical description from NHS reference:

https://www.nhs.uk/conditions/tension-headaches/

Important MRCP distinction:

Presence of nausea strongly suggests migraine rather than tension headache.

10 High-Yield MRCP Points

1. Cluster headache causes severe unilateral orbital pain

2. Migraine aura lasts 5–60 minutes

3. Migraine attacks last 4–72 hours

4. Cluster attacks last 15–180 minutes

5. Migraine patients prefer dark quiet rooms

6. Cluster patients are restless

7. Oxygen treats cluster headache

8. Propranolol prevents migraine

9. Verapamil prevents cluster headache

10. Tension headache is bilateral and pressing

Practical Example (MRCP-Style MCQ)

A 42-year-old man presents with severe right-sided headache around the eye. Attacks occur every night for 5 weeks. He develops tearing and nasal congestion during attacks. Each episode lasts about 60 minutes.

What is the most appropriate acute treatment?

A. PropranololB. AmitriptylineC. High-flow oxygenD. TopiramateE. Codeine

Answer: C — High-flow oxygen

Explanation

This is classical cluster headache:

• Severe unilateral orbital pain

• Autonomic features

• Short attacks

• Cluster pattern

First-line acute therapy is:

• High-flow oxygen

• Subcutaneous sumatriptan

Propranolol and topiramate are preventive therapies rather than acute treatments.

Practical Study-Tip Checklist

Before the exam ensure you can:

✓ Memorise attack durations✓ Recognise autonomic symptoms✓ Identify behavioural differences✓ Know acute vs preventive treatment✓ Recall aura duration✓ Distinguish unilateral vs bilateral pain✓ Identify nausea patterns✓ Recognise classic exam vignettes

Common Pitfalls

1. Confusing migraine and cluster headache

Cluster headaches have short attacks and autonomic features.

2. Forgetting oxygen therapy

High-flow oxygen is a classic MRCP answer.

3. Misinterpreting nausea

Nausea strongly favours migraine over tension headache.

4. Missing behavioural clues

Migraine → patient lies stillCluster → patient restless

5. Choosing prophylaxis instead of acute therapy

MRCP often tests acute treatment first.

FAQs

How do you distinguish migraine from tension headache in MRCP questions?

Migraine typically presents with unilateral throbbing pain, nausea, and photophobia lasting hours to days. Tension headache is bilateral, pressing, and lacks nausea.

What is the first-line treatment for cluster headache?

High-flow oxygen is first-line acute treatment. Subcutaneous sumatriptan is an alternative.

What migraine features are most tested in MRCP Part 1?

Commonly tested features include aura duration (5–60 minutes), attack duration (4–72 hours), nausea, photophobia, and preventive medications such as propranolol.

Which headache causes autonomic symptoms?

Cluster headache causes lacrimation, nasal congestion, conjunctival injection, and ptosis. These features are highly characteristic in exam questions.
