Childhood Headaches: Types, Causes, and When Brain Imaging Might Be Necessary

When a child complains of headaches, parents naturally worry. Is it just a temporary discomfort, or could it signal something more serious? Headaches are surprisingly common in children—by age 18, nearly 75% of children will have experienced significant headache pain. While most childhood headaches are benign and manageable, understanding the different types, recognizing concerning symptoms, and knowing when diagnostic imaging might be beneficial can provide both reassurance and appropriate care.

At Scan Centre Near Me, we work with pediatricians and specialists to provide neurological imaging when needed for children with headache concerns. This comprehensive guide will help you understand childhood headaches, recognize when to be concerned, and learn about the role of diagnostic imaging in headache evaluation.

Understanding Childhood Headaches: More Common Than You Think

Headaches in children are often overlooked or misattributed to other causes, yet they represent a significant source of discomfort and missed school days.

Prevalence and Impact

How Common Are Childhood Headaches?

• Approximately 40% of children experience headaches by age 7
• 50-75% report significant headaches by adolescence
• Migraines affect 8-23% of children by age 15
• Tension-type headaches occur in up to 15-25% of school-aged children
• Prevalence increases with age, especially during adolescence

Impact on Daily Life

• Leading cause of school absences
• Affects participation in social and athletic activities
• May interfere with sleep and appetite
• Can influence academic performance
• Often affects family dynamics and activities

Unique Aspects in Children

• Children may not clearly describe or localize pain
• Symptoms often differ from adult presentations
• Behavioral changes may be the primary indicator
• Headaches may manifest as abdominal pain in young children
• Pain perception and expression vary with developmental stage

Types of Headaches in Children: Understanding the Differences

Different headache types have distinct characteristics, causes, and management approaches.

Primary Headaches: When Headache Is the Condition Itself

Primary headaches are not symptoms of another underlying disease but stand-alone neurological conditions:

Migraine Headaches

Migraines in children have unique characteristics compared to adult presentations:

Common Symptoms in Children:

• Often bilateral (both sides) rather than unilateral as in adults
• Typically shorter duration (2-72 hours)
• May include nausea, vomiting, abdominal pain
• Sensitivity to light and/or sound
• May be preceded by visual disturbances (aura) or mood changes
• Often relieved by sleep

Childhood Migraine Variants:

• Abdominal migraine: Primarily manifests as periodic abdominal pain
• Cyclic vomiting syndrome: Recurrent episodes of intense nausea and vomiting
• Benign paroxysmal vertigo: Brief episodes of dizziness without headache
• Hemiplegic migraine: Temporary weakness on one side of the body
• Basilar-type migraine: Associated with brainstem symptoms (dizziness, double vision)

Tension-Type Headaches

The most common headache type in school-aged children:

Typical Characteristics:

• Bilateral pressing or tightening sensation
• Mild to moderate intensity
• Not worsened by routine physical activity
• No significant nausea or vomiting
• May have either photophobia (light sensitivity) or phonophobia (sound sensitivity), but not both
• Often described as a “band” around the head

Duration and Patterns:

• Episodic: Lasting 30 minutes to several days
• Chronic: Occurring 15 or more days per month
• Often increases during school hours and decreases during vacations
• May be associated with stress, poor sleep, or academic pressure

New Daily Persistent Headache (NDPH)

A distinct primary headache that begins suddenly and persists:

Key Features:

• Distinct, memorable onset (patients often recall exact date)
• Daily and unremitting from onset
• Typically bilateral, pressing or tightening quality
• Mild to moderate intensity
• More common in adolescents than younger children
• Often difficult to treat

Secondary Headaches: When Headaches Signal Another Condition

Secondary headaches result from another underlying cause, ranging from common illnesses to more serious conditions:

Infection-Related Headaches

Common infectious causes include:

• Viral illnesses (common cold, influenza)
• Sinusitis
• Strep throat
• Ear infections
• Meningitis or encephalitis (requiring immediate medical attention)

Head Injury and Post-Concussion Headaches

Trauma-related headaches have distinct patterns:

• May develop immediately or days after injury
• Can persist for weeks to months
• Often worsened by cognitive effort or physical activity
• May be accompanied by other post-concussion symptoms
• Require appropriate management and monitoring

Medication Overuse Headaches

Particularly in adolescents, excessive use of pain medications can cause:

• Chronic daily or near-daily headaches
• Headaches that return when medication wears off
• Typically improves after medication withdrawal
• More frequent in children with pre-existing migraine tendencies
• May require supervised withdrawal protocol

Serious Causes Requiring Prompt Evaluation

Though rare, these serious conditions may present with headache:

• Brain tumors
• Idiopathic intracranial hypertension (pseudotumor cerebri)
• Vascular abnormalities (arteriovenous malformations, aneurysms)
• Hydrocephalus
• Central nervous system infections

Common Headache Triggers in Children: Environmental and Lifestyle Factors

Understanding triggers helps with both prevention and determining when further evaluation is needed.

• Significant lifestyle impact (frequent school absences, activity limitation)
• Headaches associated with substance use or medication overuse
• New onset headaches in later adolescence

The Role of Diagnostic Imaging in Childhood Headache Evaluation

While most childhood headaches don’t require imaging studies, certain situations benefit from these diagnostic tools to rule out serious underlying conditions.

When Is Imaging Typically Recommended?

The decision to perform neuroimaging is based on careful assessment of headache characteristics and associated findings:

Clinical Scenarios Often Warranting Imaging

• Abnormal neurological examination findings
• Signs of increased intracranial pressure
• Headaches that wake children from sleep or occur early morning with vomiting
• New or progressive headaches without clear cause
• Headaches following head trauma (based on specific circumstances)
• History or physical findings suggesting potential structural abnormality
• Headaches associated with seizures or developmental delays

Age Considerations

• Higher threshold for imaging in typical migraines with normal exam in adolescents
• Lower threshold for imaging in very young children with new headaches
• Individualized approach based on specific clinical presentation

Risk-Benefit Assessment

• Balancing need for diagnostic information with minimizing unnecessary testing
• Consideration of radiation exposure (with CT scans)
• Sedation requirements for younger children (particularly with MRI)
• Parental anxiety and reassurance value
• Cost and resource utilization

Types of Neuroimaging Studies

At Scan Centre Near Me, we offer several neuroimaging modalities, each with specific advantages in headache evaluation:

Magnetic Resonance Imaging (MRI)

Generally the preferred initial imaging study for childhood headaches when indicated:

Advantages for Headache Evaluation:

• No radiation exposure
• Superior visualization of brain tissue and structures
• Better detection of small lesions and subtle abnormalities
• Excellent visualization of posterior fossa (cerebellar and brainstem regions)
• Ability to visualize vascular structures without contrast in some sequences

When It’s Particularly Valuable:

• Evaluating for tumors, developmental abnormalities, or inflammatory conditions
• Assessing for Chiari malformation or other structural issues
• Visualizing venous sinus thrombosis with appropriate sequences
• Evaluating multiple sclerosis or other white matter diseases
• Following up on abnormalities identified on CT

Specialized MRI Techniques:

• MR angiography (MRA): Evaluates blood vessels without contrast
• MR venography (MRV): Assesses venous system, particularly useful for suspected venous sinus thrombosis
• Diffusion-weighted imaging: Sensitive for acute stroke or certain tumor types
• Susceptibility-weighted imaging: Detects blood products and calcifications

Computed Tomography (CT)

While MRI is generally preferred, CT has specific applications in headache evaluation:

Advantages in Certain Scenarios:

• Rapid acquisition (seconds rather than minutes)
• Superior for detecting acute bleeding
• Better visualization of bone structures
• Greater availability in emergency settings
• Does not require sedation as often as MRI

When It’s Typically Used:

• Emergency evaluation of thunderclap headache (sudden, severe)
• After acute head trauma
• When MRI is contraindicated or unavailable
• For patients unable to tolerate MRI due to claustrophobia or implanted devices
• Initial evaluation when increased intracranial pressure is suspected

Limitations to Consider:

• Radiation exposure (particularly concerning in children)
• Less sensitive than MRI for many conditions
• Limited visualization of posterior fossa
• May miss small lesions or subtle abnormalities

Common Findings on Neuroimaging in Children with Headaches

Understanding what neuroimaging may reveal helps families prepare for potential results:

Incidental Findings vs. Significant Abnormalities

Common Incidental Findings

• Arachnoid cysts (usually no clinical significance)
• Pineal cysts (rarely symptomatic)
• Venous anomalies (normal variants in venous drainage)
• Enlarged perivascular spaces
• Minor sinusitis or fluid in sinuses

Potentially Significant Findings

• Brain tumors (primary or metastatic)
• Vascular malformations (arteriovenous malformations, cavernous malformations)
• Chiari malformation (downward displacement of cerebellar tonsils)
• Idiopathic intracranial hypertension changes
• Hydrocephalus (enlargement of ventricles)

Understanding Imaging Results

Interpretation Context

• Findings must be correlated with clinical symptoms
• Some abnormalities may be unrelated to headaches
• Normal imaging doesn’t invalidate headache symptoms
• Age-appropriate interpretation of certain findings
• Consideration of follow-up imaging for certain findings

After the Study

• Radiologist interpretation usually available within 24-48 hours
• Discussion of results with referring physician
• Determination of whether findings explain headache symptoms
• Development of treatment plan based on results
• Consideration of additional testing if indicated

Beyond Imaging: Comprehensive Headache Evaluation

Neuroimaging is just one component of a thorough headache assessment:

Additional Diagnostic Approaches

• Repeat imaging if symptoms change or worsen
• Adjustment of treatment plan based on response
• Coordination between specialists when multiple issues present
• Transition planning for chronic conditions

Case Studies: When Imaging Makes a Difference

These anonymized cases illustrate the value of appropriate neuroimaging in specific situations:

Case 1: Morning Headaches with Vomiting

Eight-year-old Aisha developed increasingly severe morning headaches accompanied by vomiting over a three-month period. Initially attributed to school anxiety, the persistent pattern and worsening intensity prompted neuroimaging. An MRI at Scan Centre Near Me revealed a posterior fossa tumor causing early signs of hydrocephalus. Early detection allowed for successful surgical removal before significant neurological complications developed, highlighting the importance of imaging when concerning patterns emerge.

Case 2: Post-Traumatic Headaches

Twelve-year-old Vikram experienced persistent headaches following a sports-related concussion. When symptoms continued beyond the expected recovery period, CT imaging revealed a small subdural hematoma requiring monitoring and specialized concussion management. Without imaging, this finding might have been missed, and his prolonged symptoms attributed solely to post-concussion syndrome. Appropriate imaging guided specific treatment approaches and recovery expectations.

Case 3: The Value of Normal Results

Fourteen-year-old Priya had classic migraine symptoms but with recent changes in pattern. Her doctor recommended an MRI to rule out secondary causes. The imaging showed no abnormalities, providing significant reassurance to both Priya and her parents. This allowed them to focus confidently on migraine management strategies without lingering worry about more serious conditions, demonstrating that even “normal” imaging results can provide valuable clinical information.

Special Considerations in Headache Imaging

Certain factors influence the approach to neuroimaging in children with headaches:

Age-Specific Approaches

Very Young Children (Under 6)

• Higher likelihood of requiring sedation for MRI
• Often unable to describe headache characteristics
• May require more extensive imaging protocols
• More difficult to distinguish primary from secondary headaches
• Often lower threshold for imaging due to communication limitations

School-Age Children (6-12)

• Increasing ability to cooperate with imaging procedures
• Better able to describe symptoms
• Developing pattern recognition possible
• Greater prevalence of primary headache disorders
• School performance impact often a key concern

Adolescents (13-18)

• Usually able to undergo imaging without sedation
• Typically provide reliable symptom reporting
• Higher prevalence of migraine and tension headaches
• Increasing psychosocial factors influencing headaches
• Importance of discussing findings directly with patient

Children with Special Needs

Imaging Challenges and Solutions

• Modified protocols for children with developmental differences
• Additional preparation for children with sensory sensitivities
• Sedation considerations for children unable to remain still
• Adapted communication strategies based on cognitive level
• Parent involvement in preparation and support
