Taking a headache history is an important skill that is often assessed in OSCEs. This guide provides a structured approach to taking a headache history in an OSCE setting.
The vast majority of headaches are not life-threatening, with tension headache and migraine being the most common diagnoses. However, in some cases, a headache may be the first indication of serious underlying pathology and therefore it is essential you are able to take a comprehensive headache history.
Introduce yourself to the patient including your name and role.
Confirm the patient’s name and date of birth.
Explain that you’d like to take a history from the patient.
Gain consent to proceed with history taking.
General communication skills
It is important you do not forget the general communication skills which are relevant to all patient encounters. Demonstrating these skills will ensure your consultation remains patient-centred and not checklist-like (just because you’re running through a checklist in your head doesn’t mean this has to be obvious to the patient).
Some general communication skills which apply to all patient consultations include:
Demonstrating empathy in response to patient cues: both verbal and non-verbal.
Active listening: through body language and your verbal responses to what the patient has said.
An appropriate level of eye contact throughout the consultation.
Open, relaxed, yet professional body language (e.g. uncrossed legs and arms, leaning slightly forward in the chair).
Making sure not to interrupt the patient throughout the consultation.
Establishing rapport (e.g. asking the patient how they are and offering them a seat).
Signposting: this involves explaining to the patient what you have discussed so far and what you plan to discuss next.
Summarising at regular intervals.
Use open questioning to explore the patient’s presentingcomplaint:
“What’s brought you in to see me today?”
“Tell me about the issues you’ve been experiencing.”
Provide the patient with enough time to answer and avoid interrupting them.
Facilitate the patient to expand on their presentingcomplaint if required:
“Ok, can you tell me more about that?”
“Can you explain what that pain was like?”
Open vs closed questions
History taking typically involves a combination of open and closedquestions. Open questions are effective at the start of consultations, allowing the patient to tell you what has happened in their own words. Closed questions can allow you to explore the symptoms mentioned by the patient in more detail to gain a better understanding of their presentation. Closed questions can also be used to identify relevant risk factors and narrow the differential diagnosis.
History of presenting complaint
The SOCRATES acronym (explained below) is a useful tool that you can use to further explore the characteristics of the patient’s headache.
Ask about the location of the headache:
“Where is the headache?”
“Can you point to where you experience the headache?”
Migraines typically present as a unilateralheadache whereas bilateralheadache is most commonly associated with a tension headache.
Clarify how and when the headache developed:
“Did the headache come on suddenly or gradually?”
“When did the headache first start?”
“How long have you been experiencing the headache?”
Headaches that have a very suddenonset, reaching their maximum intensity within seconds are typically associated with subarachnoidhaemorrhage (often described as ‘thunderclap’ in nature).
Ask about the specificcharacteristics of the headache:
“How would you describe the headache?”
“Is the headache constant or does it come and go?”
Commondescriptors of headaches may include: ‘aching’, ‘throbbing’, ‘pounding’, ‘pulsating’, ‘pressure’, ‘pins and needles’ and ‘stabbing’.
Ask if the headache movesanywhere else:
“Does the headache spread elsewhere?”
The radiation of a headache to another anatomical location may help to narrow the differential diagnosis:
Radiation to the neck is associated with meningitis.
Radiation to the face may suggest a diagnosis of trigeminalneuralgia.
Radiation to the eye occurs in acute closed-angle glaucoma.
Ask if there are other symptoms which are associated with the headache:
“Are there any other symptoms that seem associated with the headache?”
See the keysymptoms section below for examples.
Clarify how the headache has changed over time:
“How has the headache changed over time?”
“Is the headache worse at a particular time of day?”
“In a 30 day period, how many of those days would you experience the headache on average?”
Headaches that are worse in the mornings are suggestive of raisedintracranialpressure (e.g. space-occupying lesion).
Exacerbating or relieving factors
Ask if anything makes the headaches worse or better:
“Does anything seem to trigger or make the headaches worse?”
“Does anything make the headaches better?”
Triggers for headaches may include caffeine, excessive codeine use, stress, coughing (suggestive of raised ICP), lying flat (suggestive of raised ICP) and standing up (suggestive of low ICP).
Relievingfactors for headaches may include hydration, standing up (suggestive of raised ICP) and lyingdown (suggestive of low ICP).
Assess the severity of the headaches by asking the patient to grade it on a scale of 0-10:
“On a scale of 0-10, how severe is the headache, if 0 is no pain and 10 is the worst pain you’ve ever experienced?”
Ask the patient how the headaches are affecting their dailylife. Regular migraines may make it difficult for the patient to function.
Key symptoms to ask about
Keysymptoms to ask about when taking a headache history include:
Nausea and vomiting: may indicate raised intracranial pressure (e.g. space-occupying lesion).
Visual disturbance: may be migraine aura related or secondary to local neural compression by a space-occupying lesion or haemorrhage.
Photophobia: most commonly associated with migraine, but also a typical finding in meningitis which may be chemical (e.g. subarachnoid haemorrhage) or infective (e.g. bacterial meningitis).
Neck stiffness: commonly associated with meningitis but may also be due to musculoskeletal issues of the neck which can also cause headaches (cervicogenic headache).
Fever: indicative of an infective process which may be viral (e.g. HSV encephalitis), bacterial (e.g. cerebral abscess) or fungal (e.g. fungal meningitis).
Rash: a non-blanching purpuric rash may indicate meningococcal sepsis.
Weight loss: may indicate underlying malignancy (e.g. primary intracranial tumour or brain metastases).
Sleep disturbance: headaches which disturb sleep are concerning for serious underlying pathology (e.g. raised intracranial pressure).
Temporal region tenderness: associated with temporal arteritis. Patients may report tenderness when brushing their hair.
Neurological deficits: these may include motor or sensory deficits, cognitive symptoms or a reduced level of consciousness. Different patterns of these symptoms may be present in a wide range of pathology (e.g. migraine, space-occupying lesions, intracranial infection and intracranial haemorrhage).
Red flag features
It is important that you recognise red flag features in a headache history which warrant urgent further investigation.
Examples of some red flag presentations include:
A headache of sudden onset, reaching maximum intensity by five minutes (suggestive of subarachnoid haemorrhage).
Worsening headache associated with fever, meningeal irritation (i.e. neck stiffness) and altered mental status (suggestive of bacterial, viral or fungal meningitis).
New onset focal neurological deficit, personality change or cognitive dysfunction (e.g. intracranial haemorrhage, space-occupying lesion, encephalitis, meningitis).
Decreased level of consciousness (e.g. raised intracranial pressure).
Recent head trauma within the last 3 months (e.g. subdural haemorrhage).
Headache which is posture dependent (e.g. a headache worse on lying down and when coughing is suggestive of raised ICP).
Headache associated with tenderness in the temporal region (unilateral or bilateral) and jaw claudication (e.g. temporal arteritis).
Headache associated with severe eye pain, reduced vision, nausea and vomiting (e.g. acute angle-closure glaucoma).
Ideas, concerns and expectations
A key component of history taking involves exploring a patient’s ideas, concerns and expectations (often referred to as ICE) to gain insight into how a patient currently perceives their situation, what they are worried about and what they expect from the consultation.
The exploration of ideas, concerns and expectations should be fluid throughout the consultation in response to patient cues. This will help ensure your consultation is more natural, patient-centred and not overly formulaic.
It can be challenging to use the ICE structure in a way that sounds natural in your consultation, but we have provided several examples for each of the three areas below.
Explore the patient’s ideas about the current issue:
“What do you think the problem is?”
“What are your thoughts about what is happening?”
“It’s clear that you’ve given this a lot of thought and it would be helpful to hear what you think might be going on.”
Explore the patient’s current concerns:
“Is there anything, in particular, that’s worrying you?”
“What’s your number one concern regarding this problem at the moment?”
“What’s the worst thing you were thinking it might be?”
Ask what the patient hopes to gain from the consultation:
“What were you hoping I’d be able to do for you today?”
“What would ideally need to happen for you to feel today’s consultation was a success?”
“What do you think might be the best plan of action?”
Summarise what the patient has told you about their presenting complaint. This allows you to check your understanding of the patient’s history and provides an opportunity for the patient to correct any inaccurate information.
Once you have summarised, ask the patient if there’s anything else that you’ve overlooked. Continue to periodically summarise as you move through the rest of the history.
Signposting, in a history taking context, involves explicitly stating what you have discussed so far and what you plan to discuss next. Signposting can be a useful tool when transitioning between different parts of the patient’s history and it provides the patient with time to prepare for what is coming next.
Explain what you have covered so far: “Ok, so we’ve talked about your symptoms, your concerns and what you’re hoping we achieve today.”
What you plan to cover next: “Next I’d like to quickly screen for any other symptoms and then talk about your past medical history.”
A systemicenquiry involves performing a brief screen for symptoms in other body systems which may or may not be relevant to the primary presenting complaint. A systemic enquiry may also identify symptoms that the patient has forgotten to mention in the presenting complaint.
Deciding on which symptoms to ask about depends on the presenting complaint and your level of experience.
Some examples of symptoms you could screen for in each system include:
“Are you currently seeing a doctor or specialist regularly?”
If the patient does have a medical condition, you should gather more details to assess howwellcontrolled the disease is and what treatment(s) the patient is receiving. It is also important to ask about any complications associated with the condition including hospitaladmissions.
Ask if the patient has previously undergone any surgery or procedures (e.g. neurosurgery):
“Have you ever previously undergone any operations or procedures?”
“When was the operation/procedure and why was it performed?”
Ask if the patient has any allergies and if so, clarify what kind of reaction they had to the substance (e.g. mild rash vs anaphylaxis).
Examples of relevant medical conditions
Medicalhistory relevant to headaches includes:
Recent head trauma (last three months)
Benign intracranial hypertension
Cerebrospinal fluid shunt devices (blocked or overdraining shunts present with headache)
Acute angle-closure glaucoma
Cancer (any site due to potential of brain metastases)
Hypertension (risk of malignant hypertension and haemorrhagic stroke)
Infectious disease (risk of cerebral abscess)
Thrombophilia (increased risk of venous sinus thrombosis)
Bleeding disorders (increased risk of intracranial bleeding)
Polymyalgia rheumatica (increased risk of temporal arteritis)
Ask if the patient is currently taking any prescribedmedications or over-the-counterremedies:
“Are you currently taking any prescribed medications or over-the-counter treatments?”
If the patient is taking prescribed or over the counter medications, document the medicationname, dose, frequency, form and route. Specifically ask about blood-thinning medications such as aspirin, warfarin and NOACs (e.g. apixaban).
Ask the patient if they’re currently experiencing any sideeffects from their medication:
“Have you noticed any side effects from the medication you currently take?”
Ask the patient if they are using any medication to treat their headaches and gather details of how frequently they are using these medications:
“Are you currently taking anything to treat the headaches?”
“How many days in a month are you using the medications?”
Medication overuse headache is counterintuitively associated with medications used for the treatment of headache. Overuse of these medications is defined as use on more than 15 days of a month. Medications which are associated with medication-overuse headaches include:
Opiates (e.g. codeine and co-codamol)
NSAIDs (e.g. ibuprofen, aspirin)
Ask the patient if there is any familyhistory of headaches, cancer, bleeds on the brain, clotting disorders or bleeding disorders:
“Do any of your parents or siblings have problems with headaches such as migraines?”
“Have your parents or siblings ever been told they have a bleeding or clotting disorder?”
“Have your parents or siblings ever suffered from bleeds on the brain or cancer?”
Clarify at what age these diseases developed (disease developing at a younger age is more likely to be associated with genetic factors):
“At what age did your father develop the subarachnoid haemorrhage?”
“When was your mother first diagnosed with lung cancer”
If one of the patient’s close relatives are deceased, sensitively determine the age at which they died and the cause of death:
“I’m really sorry to hear that, do you mind me asking how old your dad was when he died?”
“Do you remember what medical condition was felt to have caused his death?”
Explore the patient’s socialhistory to both understand their socialcontext and identify potential risk factors for headaches.
General social context
Explore the patient’s general social context including:
the type of accommodation they currently reside in (e.g. house, bungalow) and if there are any adaptations to assist them (e.g. stairlift)
whether there is a gas fire or boiler and if they have a carbon monoxide detector (carbon monoxide poisoning can present with headache and drowsiness)
who else the patient lives with and their personal support network
what tasks they are able to carry out independently and what they require assistance with (e.g. self-hygiene, housework, food shopping)
if they have any carer input (e.g. twice daily carer visits)
Record the patient’s smokinghistory, including the type and amount of tobacco used.
Calculate the number of ‘pack-years‘ the patient has smoked for to determine their risk profile:
pack-years = [number of years smoked] x [average number of packs smoked per day]
one pack is equal to 20 cigarettes
Smoking is an important risk factor for both malignancy and thromboticdisease.
Record the frequency, type and volume of alcohol consumed on a weekly basis.
Alcohol can cause headaches, particularly when used excessively. Patients may also experience alcoholwithdrawal headaches.
Recreational drug use
Ask the patient if they use recreationaldrugs and if so determine the type of drugs used and their frequency of use. Headaches can be associated with the use of cocaine, amfetamine and cannabis.
Ask about the patient’s current occupation:
Assess the impact of their symptoms on their ability to work.
Ask about their responsibilities and identify potential exposure to agents such as carbon monoxide which can cause headaches.
Closing the consultation
Summarise the keypoints back to the patient.
Ask the patient if they have any questions or concerns that have not been addressed.
