Headaches in Children: Clinical Case and VIva Q&A

Document
1. Clinical Case of Headaches in Children

Patient: Sarah, 9-year-old female
Chief Complaint: Recurrent headaches for the past 3 months

History of Present Illness:
Sarah, a previously healthy 9-year-old girl, presents to the pediatric clinic with her mother, reporting recurrent headaches over the past 3 months. The headaches occur 2-3 times per week, typically in the afternoon after school. Sarah describes the pain as throbbing, primarily located in the frontal region bilaterally. The pain intensity ranges from 4-7 out of 10 on a pain scale.

Each episode lasts 2-4 hours and is occasionally associated with nausea, but no vomiting. Sarah reports sensitivity to light and sound during these episodes. The headaches often improve with rest in a dark, quiet room. Over-the-counter ibuprofen provides partial relief.

Sarah's mother notes that the headaches seem to worsen during periods of academic stress or when Sarah hasn't slept well. There's no history of head trauma, visual changes, or neurological symptoms. Sarah has missed several days of school due to these headaches.

Past Medical History: Unremarkable
Family History: Mother suffers from migraines
Social History: Lives with both parents and a younger sister. Performs well academically but reports increased stress due to upcoming exams.

Physical Examination:

  • Vital Signs: Within normal limits
  • General: Alert, cooperative, no acute distress
  • HEENT: Normocephalic, atraumatic. No sinus tenderness. Fundi normal.
  • Neurological: Cranial nerves intact. Normal motor and sensory function. No meningeal signs.

Assessment: Suspected migraine headaches in a pediatric patient

Plan:

  1. Educate patient and family about migraine headaches
  2. Recommend lifestyle modifications: regular sleep schedule, stress reduction techniques, and proper hydration
  3. Start a headache diary to identify potential triggers
  4. Prescribe sumatriptan nasal spray for acute attacks
  5. Consider prophylactic therapy if frequency increases
  6. Follow-up in 4 weeks to assess response to treatment
  7. Neuroimaging not indicated at this time given the absence of red flag symptoms
2. Varieties of Clinical Presentations of Headaches in Children
  1. Migraine without Aura:
    • Recurrent, pulsating headaches lasting 2-72 hours
    • Unilateral or bilateral pain, often frontal or temporal
    • Associated with nausea, vomiting, photophobia, and phonophobia
    • May experience pallor, dizziness, or abdominal pain
  2. Migraine with Aura:
    • Similar to migraine without aura, but preceded by neurological symptoms
    • Visual aura: flickering lights, spots, or lines
    • Sensory aura: numbness or tingling, usually unilateral
    • Rarely, motor weakness or speech disturbances
  3. Tension-type Headache:
    • Bilateral, pressing or tightening sensation
    • Mild to moderate intensity, not aggravated by physical activity
    • No nausea or vomiting, but may have photophobia or phonophobia
    • Often described as a "band-like" pressure around the head
  4. Chronic Daily Headache:
    • Headaches occurring 15 or more days per month for over 3 months
    • Can be a mix of migraine and tension-type headaches
    • Often associated with medication overuse
    • Significant impact on daily activities and quality of life
  5. Cluster Headache:
    • Rare in children, more common in adolescents
    • Severe unilateral pain, often periorbital
    • Associated with autonomic symptoms: conjunctival injection, lacrimation, nasal congestion
    • Attacks occur in clusters, lasting weeks to months, followed by remission periods
  6. Secondary Headaches:
    • Due to underlying conditions such as sinusitis, dental problems, or vision issues
    • Can be caused by intracranial pathologies like tumors or increased intracranial pressure
    • May present with "red flag" symptoms like sudden onset, worsening pattern, or neurological deficits
  7. Abdominal Migraine:
    • Recurrent episodes of moderate to severe abdominal pain
    • Associated with nausea, vomiting, pallor
    • May or may not be accompanied by head pain
    • Typically lasts 1-72 hours
3. Viva Questions and Answers Related to Headaches in Children

  1. Q: What are the key differences between adult and pediatric migraine presentations?

    A: Pediatric migraines often differ from adult presentations in several ways:

    • Duration: Pediatric migraines may be shorter, lasting 2-72 hours compared to 4-72 hours in adults.
    • Location: Children more commonly experience bilateral headaches, while adults typically have unilateral pain.
    • Associated symptoms: Children may have more pronounced gastrointestinal symptoms and may struggle to describe photophobia or phonophobia.
    • Aura: Visual auras are less common in children, especially younger ones.
    • Behavior: Children often seek a quiet, dark place to rest, whereas adults might try to push through their activities.

  2. Q: What are the diagnostic criteria for migraine without aura in children according to ICHD-3?

    A: According to the International Classification of Headache Disorders 3rd edition (ICHD-3), the diagnostic criteria for migraine without aura in children are:

    • At least 5 attacks fulfilling criteria B-D
    • Headache attacks lasting 2-72 hours (untreated or unsuccessfully treated)
    • Headache has at least two of the following characteristics:
      • Unilateral or bilateral location
      • Pulsating quality
      • Moderate or severe pain intensity
      • Aggravation by or causing avoidance of routine physical activity
    • During headache, at least one of the following:
      • Nausea and/or vomiting
      • Photophobia and phonophobia
    • Not better accounted for by another ICHD-3 diagnosis

  3. Q: How does chronic migraine differ from episodic migraine in children?

    A: Chronic migraine in children differs from episodic migraine in the following ways:

    • Frequency: Chronic migraine occurs on 15 or more days per month for more than 3 months, while episodic migraine occurs less frequently.
    • Duration: In chronic migraine, headaches last 2 hours or more per day on average.
    • Characteristics: At least 8 days per month must meet criteria for migraine or respond to migraine-specific treatment.
    • Impact: Chronic migraine often has a more significant impact on daily functioning and quality of life.
    • Treatment approach: Chronic migraine usually requires more aggressive preventive strategies and lifestyle modifications.
    • Prognosis: Chronic migraine can be more challenging to manage and may persist into adulthood if not addressed early.

  4. Q: What are the common triggers for migraines in children, and how do they differ from adults?

    A: Common triggers for migraines in children include:

    • Stress (e.g., academic pressures, social issues)
    • Irregular sleep patterns
    • Skipping meals
    • Dehydration
    • Certain foods (e.g., chocolate, caffeine, processed meats)
    • Weather changes
    • Bright lights or loud noises
    • Hormonal changes (especially in adolescents)
    Differences from adult triggers:
    • Children may be more sensitive to dietary triggers
    • School-related stress is more prominent in children
    • Hormonal triggers are less common in pre-pubertal children
    • Screen time and electronic device use may be more significant triggers for children
    • Children may have difficulty identifying or articulating their triggers

  5. Q: What are the red flag symptoms in pediatric headaches that warrant immediate attention or neuroimaging?

    A: Red flag symptoms in pediatric headaches include:

    • Sudden onset of severe headache (thunderclap headache)
    • Progressively worsening headache pattern
    • Headache that wakes the child from sleep or is worse in the morning
    • Associated neurological deficits (e.g., weakness, numbness, visual changes)
    • Alteration in mental status or personality changes
    • Headache associated with fever and neck stiffness
    • New onset of headache in a child under 6 years old
    • Headache following head trauma
    • Headache associated with vomiting, especially early morning vomiting
    • Presence of papilledema on fundoscopic examination
    • Headache in immunocompromised patients
    These symptoms may indicate serious underlying conditions such as intracranial tumors, infections, or increased intracranial pressure, and warrant immediate medical attention and consideration for neuroimaging.

  6. Q: How do you approach the management of acute migraine attacks in children?

    A: The management of acute migraine attacks in children involves:

    1. Non-pharmacological measures:
      • Rest in a quiet, dark room
      • Application of cold or warm compresses
      • Encouraging sleep
      • Proper hydration
    2. Pharmacological treatment:
      • First-line: Ibuprofen or acetaminophen (paracetamol)
      • Second-line: Triptans (e.g., sumatriptan nasal spray) for children ≥12 years old, or younger with appropriate approval
      • Antiemetics for associated nausea and vomiting
    3. Timing: Emphasize early treatment at the onset of migraine for better efficacy
    4. Dosing: Use weight-based dosing for medications
    5. Avoid overuse: Limit acute medications to <10-15 days per month to prevent medication overuse headache
    6. Education: Teach children to recognize early symptoms and initiate treatment promptly
    7. Follow-up: Assess efficacy and tolerability of treatments at subsequent visits

  7. Q: What preventive strategies are recommended for children with frequent migraines?

    A: Preventive strategies for children with frequent migraines include:

    1. Lifestyle modifications:
      • Regular sleep schedule
      • Balanced meals and hydration
      • Regular exercise
      • Stress management techniques (e.g., mindfulness, relaxation exercises)
      • Limiting screen time
    2. Behavioral interventions:
      • Cognitive Behavioral Therapy (CBT)
      • Biofeedback
    3. Pharmacological prophylaxis (if ≥4 disabling attacks per month):
      • First-line options: Topiramate, amitriptyline, propranolol
      • Second-line options: Valproic acid, gabapentin (consider in adolescents)
      • Newer options: CGRP monoclonal antibodies (for adolescents, where approved)
    4. Nutraceuticals:
      • Riboflavin (Vitamin B2)
      • Magnesium
      • Coenzyme Q10
    5. Trigger avoidance based on individual trigger identification
    6. Regular follow-up to assess efficacy and adjust treatment as needed
    7. Patient and family education about migraine management
    The choice of preventive strategy should be individualized based on the child's age, frequency and severity of migraines, comorbidities, and patient/family preferences.

  8. Q: How do you differentiate between migraine and tension-type headaches in children?

    A: Differentiating between migraine and tension-type headaches in children involves considering several factors:

    Feature Migraine Tension-type Headache
    Pain quality Throbbing or pulsating Pressing or tightening
    Pain intensity Moderate to severe Mild to moderate
    Location Often unilateral (bilateral in children) Typically bilateral
    Duration 2-72 hours 30 minutes to 7 days
    Associated symptoms Nausea, vomiting, photophobia, phonophobia Mild photophobia or phonophobia (not both)
    Effect on activity Often interferes with daily activities Generally does not interfere significantly
    Aggravating factors Physical activity often worsens pain Not typically aggravated by routine activities
    Aura May be present (in migraine with aura) Absent
    Family history Often positive for migraines Less commonly reported
    It's important to note that these features can overlap, and some children may experience both types of headaches. A detailed history, headache diary, and physical examination are crucial for accurate diagnosis.

  9. Q: What is the role of neuroimaging in the evaluation of pediatric headaches?

    A: The role of neuroimaging in pediatric headaches is primarily to rule out secondary causes of headache, especially when red flag symptoms are present. Key points include:

    • Routine neuroimaging is not recommended for children with recurrent headaches and normal neurological examinations.
    • Neuroimaging (MRI preferred over CT) is indicated when:
      • Abnormal neurological examination findings are present
      • Red flag symptoms exist (e.g., sudden severe headache, progressive worsening, personality changes)
      • Headaches wake the child from sleep or are worse in the morning
      • There's a history of seizures or neurocutaneous syndromes
      • Headaches are associated with persistent vomiting or visual changes
    • MRI is preferred over CT due to lack of radiation exposure and better visualization of posterior fossa structures.
    • Neuroimaging can help diagnose conditions such as brain tumors, hydrocephalus, vascular malformations, or sinusitis.
    • The decision to perform neuroimaging should be based on a thorough clinical evaluation and discussion with the family about the risks and benefits.

  10. Q: How do you diagnose and manage medication overuse headache (MOH) in children?

    A: Diagnosis and management of medication overuse headache (MOH) in children involves: Diagnosis:

    • Headache occurring on ≥15 days/month in a patient with pre-existing headache disorder
    • Regular overuse for >3 months of one or more acute/symptomatic treatment drugs:
      • Triptans, opioids, or combination analgesics used on ≥10 days/month
      • Simple analgesics (e.g., NSAIDs, acetaminophen) used on ≥15 days/month
    • Headache has developed or markedly worsened during medication overuse
    Management:
    1. Education: Explain MOH to the patient and family
    2. Withdrawal of overused medication:
      • Abrupt withdrawal is usually recommended
      • Gradual tapering may be necessary for some medications (e.g., opioids)
    3. Bridge therapy: Short-term use of alternative medications (e.g., naproxen) to manage withdrawal symptoms
    4. Prophylactic treatment: Start or optimize preventive therapy
    5. Behavioral interventions: Implement stress management techniques, lifestyle modifications
    6. Follow-up: Regular monitoring to prevent relapse
    7. Consider multidisciplinary approach involving pain specialists, psychologists
    Prevention of MOH is crucial through education about proper use of acute medications and early implementation of preventive strategies in children with frequent headaches.

  11. Q: What are the indications for pediatric headache specialist referral?

    A: Indications for pediatric headache specialist referral include:

    1. Diagnostic uncertainty or complex headache presentations
    2. Presence of concerning neurological symptoms or signs
    3. Chronic daily headache or chronic migraine
    4. Medication overuse headache
    5. Failure of first-line preventive treatments
    6. Need for specialized treatments (e.g., nerve blocks, Botox injections)
    7. Comorbid conditions complicating headache management (e.g., depression, anxiety)
    8. Headaches significantly impacting school attendance or daily functioning
    9. Young children (under 5 years) with recurrent headaches
    10. Need for multidisciplinary care (e.g., pain psychology, physical therapy)
    11. Consideration of clinical trials or newer therapies
    12. Patient or family request for specialist consultation
    Early referral to a pediatric headache specialist can lead to more effective management and improved outcomes for children with complex or refractory headache disorders.

  12. Q: How do you approach the diagnosis and management of abdominal migraine in children?

    A: Approach to diagnosis and management of abdominal migraine in children: Diagnosis:

    • At least 5 attacks fulfilling criteria:
    • Abdominal pain:
      • Location: midline, periumbilical, or poorly localized
      • Quality: dull or 'just sore'
      • Moderate to severe intensity
    • Episodes last 2-72 hours
    • Associated symptoms: at least 2 of:
      • Anorexia
      • Nausea
      • Vomiting
      • Pallor
    • Episodes are separated by weeks to months
    • Not attributed to another disorder
    Management:
    1. Education: Explain the condition to the child and family
    2. Lifestyle modifications:
      • Regular sleep schedule
      • Balanced diet and regular meals
      • Stress management techniques
    3. Acute treatment:
      • NSAIDs (e.g., ibuprofen)
      • Triptans in some cases (off-label use)
      • Antiemetics for associated nausea
    4. Preventive treatment (if frequent or severe episodes):
      • Cyproheptadine
      • Propranolol
      • Topiramate
      • Amitriptyline
    5. Trigger identification and avoidance
    6. Consider cognitive behavioral therapy
    7. Regular follow-up to assess efficacy of management
    It's important to rule out other gastrointestinal and systemic disorders before diagnosing abdominal migraine. Collaboration with a pediatric gastroenterologist may be beneficial in some cases.

  13. Q: What are the key differences in migraine presentation and management between pre-pubertal and adolescent children?

    A: Key differences in migraine presentation and management between pre-pubertal and adolescent children include: Presentation:

    • Duration: Pre-pubertal migraines are often shorter (1-2 hours) compared to adolescents (4-72 hours)
    • Location: Bilateral in pre-pubertal children, more likely to be unilateral in adolescents
    • Aura: Less common in younger children, more frequent in adolescents
    • Associated symptoms: Younger children may have more pronounced gastrointestinal symptoms
    • Triggers: Hormonal triggers more common in post-pubertal adolescents
    Management:
    • Acute treatment:
      • Pre-pubertal: Focus on NSAIDs and acetaminophen
      • Adolescents: Triptans more commonly used and approved
    • Preventive treatment:
      • Pre-pubertal: Limited options, focus on lifestyle modifications and non-pharmacological approaches
      • Adolescents: More pharmacological options available, including adult medications
    • Lifestyle factors:
      • Pre-pubertal: Greater emphasis on family-based interventions
      • Adolescents: More focus on sleep hygiene, stress management, and screen time
