Headache Decision Making
Most headaches are not caused by a serious brain condition, but some may indicate an underlying disorder. This decision-making guide explains when headaches should be evaluated, possible causes, available diagnostic tests, and how specialists determine the most appropriate treatment pathway.
Headache: Diagnosis, Treatment Options & Decision-Making Overview
Does a headache need further evaluation? Headaches are one of the most common neurological symptoms, and in most cases they are not caused by a serious underlying condition. However, some headaches may indicate an underlying neurovascular disorder such as a brain aneurysm, stroke, brain arteriovenous malformation (AVM), or other vascular abnormality that requires specialist assessment.
Because headaches can vary greatly in their cause, severity, and associated symptoms, determining when reassurance is appropriate and when further assessment is needed is an important part of clinical decision-making.
This guide explains how headaches are evaluated, when specialist assessment may be recommended, and how treatment decisions are made based on your symptoms, medical history, and imaging findings.
Quick Decision Guide
Most headaches are not caused by a serious brain condition.
However, specialist evaluation may be appropriate if your headache is:
- Sudden and severe ("thunderclap" headache)
- Different from your usual headaches
- Becoming progressively worse over time
- Associated with vision changes, weakness, numbness or speech difficulties
- Accompanied by seizures or loss of consciousness
- Persistent despite appropriate treatment
- Occurring after treatment for a neurovascular condition
Understanding Headaches
Headaches can generally be divided into two broad categories:
Primary Headaches
These headaches are not caused by another underlying disease and include conditions such as:
- Migraine
- Tension-type headache
- Cluster headache
Although often painful, these headaches are usually managed medically and are not typically associated with structural abnormalities in the brain.
Secondary Headaches
Secondary headaches occur because of another underlying condition.
Potential causes include:
- Brain aneurysm
- Stroke
- Brain arteriovenous malformation (AVM)
- Dural arteriovenous fistula (DAVF)
- Brain tumours
- Infection
- Raised intracranial pressure
- Medication-related causes
Identifying the underlying cause is essential because treatment depends on the diagnosis rather than the headache itself.
Migraine or Something More Serious?
Migraines are one of the most common causes of recurrent headaches and are usually a primary headache disorder. However, some symptoms can overlap with those seen in certain neurovascular conditions, leading many patients to wonder whether their headaches could be related to a brain aneurysm or another underlying vascular abnormality.
Although migraines do not cause brain aneurysms, a sudden change in headache pattern, a "worst-ever" headache, or headaches accompanied by neurological symptoms should be medically assessed to exclude more serious conditions.
Specialist evaluation focuses on understanding your headache history, associated symptoms, neurological examination, and whether imaging is appropriate based on your individual presentation.

When Should a Headache Be Evaluated?
Most headaches do not require extensive testing.
However, further evaluation may be recommended if symptoms suggest a secondary cause.
These include:
- A sudden "worst headache of your life"
- New headaches after the age of 50
- Headaches associated with neurological symptoms
- Headaches following trauma
- Progressive headaches
- Persistent headaches despite treatment
- Abnormal neurological examination
Depending on your presentation, evaluations may include CT, MRI, CT angiography, MRI angiography or cerebral angiography.
Could My Headache Be Related to a Brain Aneurysm?
Many patients worry that a headache could be caused by a brain aneurysm. In reality, most headaches are not due to a brain aneurysm, but certain headache patterns may require urgent assessment.
These include:
- Thunderclap headaches
- Sentinel headaches
- Headaches associated with neurological symptoms
- Sudden severe headaches unlike previous episodes

Could My Headache Be Related to Another Neurovascular Condition?
Although uncommon, headaches may also be associated with other cerebrovascular disorders, including:
- Brain arteriovenous malformations (AVMs)
- Dural arteriovenous fistulas (DAVFs)
- Stroke
- Other abnormalities affecting blood flow within the brain
These conditions often require specialist imaging and careful interpretation to determine whether the headache is related to an underlying vascular abnormality or another cause.
Choosing the Right Headache Specialist in Singapore
Not every headache requires a neurointerventional specialist. However, referral may be appropriate when:
- Imaging identifies a vascular abnormality
- A brain aneurysm or AVM is suspected
- Symptoms remain unexplained
- A second opinion is required
- Neurovascular treatment options are being considered
A specialist consultation focuses on identifying the underlying cause of the headache and determining whether observation, further evaluation, or treatment is appropriate.
Headache Treatment Options
Treatment depends entirely on the underlying diagnosis.
Management may include:
- Medical treatment for primary headache disorders
- Lifestyle modifications
- Preventive medications
- Imaging surveillance
- Endovascular treatment
- Microsurgery
- Other neurovascular interventions where appropriate
The goal is to treat the cause of the headache rather than simply relieving symptoms.

Most headaches are not caused by a serious neurological condition, but certain headache patterns should never be ignored. Careful clinical assessment, supported by the appropriate imaging when indicated, allows us to distinguish common headache disorders from the uncommon but important neurovascular conditions that require timely treatment. Our priority is to provide patients with a clear diagnosis, reassurance where appropriate, and personalised care when further intervention is needed.
Take the Next Step With a Neurointerventional Specialist
If you are experiencing persistent headaches, sudden severe headaches, or headaches associated with neurological symptoms, a comprehensive assessment can help determine whether further evaluation is needed and identify the most appropriate management plan.
A specialist consultation may include:
- Detailed review of your symptoms and medical history
- Assessment of neurological and vascular risk factors
- Review of previous CT, MRI or angiography imaging
- Recommendations for further evaluations where appropriate
- Personalised treatment or monitoring plan based on your diagnosis
At the Supreme Vascular and Interventional Clinic in Singapore, every patient is assessed individually to determine whether their headaches are part of a primary headache disorder or an underlying neurovascular condition requiring specialist care. We invite you to schedule a consultation with Dr. Manish Taneja for a personalised assessment.

Controllable risk factors are lifestyle choices that can be changed to reduce the risk of having a stroke including managing your cholesterol.
We’ve Got You Covered for Specialized Stroke Screening, Prevention, and Management
Imagine heart attacks where the blood flow to your heart is blocked. Similarly, a stroke occurs when the blood flow to your brain is interrupted becoming a “brain attack”, affecting a blood vessel and surrounding brain function. When blood supply does not reach a certain part, brain cells begin to die. Different types of stroke include ischemic strokes or a mini stroke, a TIA (transient ischemic attack). Common risk factors include high blood pressure, which increases strain on the blood vessel and raises the likelihood of a stroke. Symptoms can vary, but may include difficulty in speaking and other changes depending on how blood flow is affected. Understanding risk factors and acting early can make a difference. It’s important to work closely with a specialist to monitor your health and reduce stroke risk.
