Question:

A 23-year-old woman reports recurrent headaches preceded by flashing zigzag lines that disappear completely before the pain settles. Between attacks, neurological examination is normal. Which interpretation best fits these visual symptoms?

Options:

Correct Answer: A reversible neurological aura associated with migraine

Explanation: Migraine aura consists of fully reversible neurological symptoms, commonly visual phenomena such as flashing lights or zigzag lines, occurring before or around the headache.

Question:

A 32-year-old woman with migraine develops prominent nausea and vomiting during attacks, making oral treatment difficult. Which drug category is most useful as an adjunct to her acute headache treatment?

Options:

Correct Answer: Antiemetic drugs

Explanation: Antiemetics are useful adjuncts when nausea and vomiting accompany acute migraine and may also make administration of other acute therapy easier.

Question:

A 39-year-old man is diagnosed with cluster headache and experiences several attacks each day. His clinician wants a treatment that can suppress attacks rapidly while a longer-term preventive drug begins to work. Which approach best matches this purpose?

Options:

Correct Answer: A short course of corticosteroid therapy

Explanation: Corticosteroids may provide short transitional prevention in cluster headache while a longer-term preventive treatment becomes effective.

Question:

A 29-year-old woman with recurrent migraine is being considered for prophylaxis. She is planning pregnancy and asks which commonly used preventive drug requires particular caution because of an important teratogenic risk.

Options:

Correct Answer: Valproate

Explanation: Valproate is an effective migraine preventive drug but has important teratogenic risk, making reproductive context highly relevant to drug selection.

Question:

A patient with migraine asks why a triptan is generally preferred over ergotamine when both can relieve an acute attack. Which pharmacological difference best supports this preference?

Options:

Correct Answer: Triptans have more selective antimigraine receptor actions

Explanation: Ergotamine has broader serotonergic and adrenergic effects with prolonged vasoconstriction, whereas triptans act more selectively on migraine-related 5-HT1 receptors.

Question:

A 58-year-old patient develops a new persistent headache accompanied by fever and neck stiffness. Which principle should guide management before classifying the pain as a primary headache disorder?

Options:

Correct Answer: Investigate an important secondary cause

Explanation: Fever with meningism is a headache red flag and requires evaluation for a secondary neurological or systemic cause before routine primary-headache treatment.

Question:

A 44-year-old woman is taking a preventive migraine drug and develops progressive weight gain, daytime sedation and low mood. Which drug best matches this adverse-effect pattern?

Options:

Correct Answer: Flunarizine

Explanation: Flunarizine may cause sedation, weight gain and depressive symptoms; extrapyramidal adverse effects are another important concern.

Question:

A 37-year-old patient reports headache on most days for several months. The episodes vary between migraine-like and pressure-type symptoms. Which statement best describes the term “chronic daily headache” in this context?

Options:

Correct Answer: It is a descriptive clinical category rather than one specific disease

Explanation: Chronic daily headache describes frequent headache over a prolonged period and can include chronic migraine, chronic tension-type headache or medication-related headache.

Question:

A 50-year-old man with cluster headache is started on preventive treatment. Because the chosen drug can affect cardiac conduction, the clinician plans appropriate cardiovascular monitoring. Which drug has most likely been prescribed?

Options:

Correct Answer: Verapamil

Explanation: Verapamil is an important preventive drug for cluster headache, and its effects on cardiac conduction are a clinically relevant safety consideration.

Question:

A 34-year-old woman has recurrent pulsating headaches associated with nausea. She notices that climbing stairs and routine physical activity make the pain worse, so she prefers to lie quietly during attacks. Which headache pattern is best supported?

Options:

Correct Answer: Migraine

Explanation: Migraine commonly worsens with routine physical activity and is frequently associated with nausea, photophobia or phonophobia.

Question:

A 63-year-old patient with a known malignancy develops a new persistent headache that differs from previous occasional headaches. Neurological examination is currently normal. Which feature most strongly affects the clinical approach?

Options:

Correct Answer: New headache in the setting of malignancy

Explanation: Malignancy is an important red-flag context for a new headache because secondary intracranial disease must be considered even if examination is initially normal.

Question:

A patient with chronic cluster headache is considered for lithium therapy after difficulty controlling recurrent attacks. Which pharmacological consideration is particularly important with this drug?

Options:

Correct Answer: It requires careful monitoring because of a narrow therapeutic range

Explanation: Lithium may be used for selected patients with cluster headache, but its narrow therapeutic range and adverse-effect profile require careful monitoring.

Question:

A 36-year-old woman with recurrent headaches is asked to record attack frequency, duration, associated symptoms, possible triggers and medication use for several weeks. What is the main clinical purpose of this intervention?

Options:

Correct Answer: To clarify the headache pattern and factors maintaining it

Explanation: A headache diary helps define frequency, triggers, associated features and medication use, supporting diagnosis and long-term management decisions.

Question:

A woman receives a preventive medication for recurrent migraine. At follow-up, pulse rate is markedly reduced and she complains of fatigue. Which drug best explains this finding?

Options:

Correct Answer: Propranolol

Explanation: Propranolol is a β-blocker used for migraine prevention; bradycardia and fatigue are important adverse effects related to β-adrenergic blockade.

Question:

A 25-year-old man with severe unilateral orbital headache and ipsilateral lacrimation presents during an acute attack. A migraine-specific drug is unavailable. Which non-drug acute treatment is particularly relevant to this headache disorder?

Options:

Correct Answer: Oxygen therapy

Explanation: Oxygen is an important non-pharmacological acute treatment for cluster headache and can provide rapid relief during an attack.

Question:

A 68-year-old man with no previous headache history develops a new recurrent headache over the last month. There are no focal neurological deficits. Which feature itself warrants greater caution than would be required for a familiar long-standing primary headache?

Options:

Correct Answer: New headache beginning later in life

Explanation: A new headache arising later in life is a red-flag feature and should prompt consideration of secondary causes even if examination is initially normal.

Question:

A 30-year-old patient taking ergotamine for migraine develops nausea, leg cramps and tingling in the feet after repeated use. Which additional finding would most strongly indicate progression to serious ergot toxicity?

Options:

Correct Answer: Cold painful extremities with impaired perfusion

Explanation: Severe ergotism results from excessive prolonged vasoconstriction and may progress from paresthesia and cramps to limb ischemia and tissue injury.

Question:

A 28-year-old woman in the postpartum period develops a new severe headache unlike any previous headache. Which aspect of the history should most influence the clinician’s decision not to manage it as routine primary headache?

Options:

Correct Answer: The headache is new in the postpartum period

Explanation: A new unusual headache during pregnancy or the postpartum period is a red flag and requires assessment for a secondary cause.

Question:

A 42-year-old woman with recurrent migraine has relatively infrequent attacks that are effectively controlled when they occur. She asks why her clinician has not automatically started daily preventive medication. Which principle best explains this decision?

Options:

Correct Answer: Prophylaxis is mainly considered when attacks are sufficiently frequent or disabling

Explanation: Preventive therapy is individualized and is considered when attack frequency, duration or disability justifies regular treatment rather than acute therapy alone.

Question:

A 35-year-old man with persistent headache has significant anxiety and poor sleep. His headache has a stable bilateral pressure-like pattern, neurological examination is normal, and there are no red flags. Which interpretation best reflects an integrated clinical approach?

Options:

Correct Answer: Psychosocial factors may contribute without making the pain imaginary

Explanation: Stress, anxiety and poor sleep can aggravate chronic tension-type headache, but they should be treated as contributing factors rather than used to dismiss genuine pain.
