1. Introduction
     Headaches are common in children, increasing in frequency from childhood to
     adolescence, affecting 80-90% by the age of 15 years. They account for 0.7%-1.3% of
     all paediatric emergency department visits. The vast majority of headaches are not
     caused by sinister pathology, but clearly our aim is to identify those with potential
     serious causes as well as diagnosing and treating those with benign causes. These
     guidelines have been developed to try and help you with this. Please also refer to SCH
     ED Guidelines Handbook.

     Headaches are classified into primary (e.g. migraine, tension, cluster headaches) and
     secondary (headache being a symptom caused by an underlying intracranial or
     medical condition).

     Headaches are also classified according to time scale:
1)   Acute; 1st presentation of primary headache or if severe, serious intracranial pathology
     e.g. Sub arachnoid haemorrhage (SAH)
2)   Acute recurrent; usually seen with primary headaches
3)   Chronic and progressive; suggesting progressive intracranial pathology
4)   Chronic non-progressive; usually due to chronic primary or chronic secondary causes.

2. Intended Audience
      Healthcare professionals working in Sheffield Children’s Hospital

3. Guideline Content
A.    ASSESSMENT
I.    History
      • All children need a detailed history, including headache onset, duration, severity,
        progression over time, exacerbating factors and associated symptoms
         (see table in section C for characteristics of headache types).
      • Ask about frequency and effect of analgesia.
      • A headache diary may be helpful. (minimum 8 weeks)
      • Personal history of previous CNS irradiation or head injury.

      • Family history of migraines, headaches, brain tumour, leukaemia, sarcoma or early
        onset breast cancer.
      • Personal or FH of Neurofibromatosis or Tuberous sclerosis and other familial
        genetic syndromes.

      Red Flags: Symptoms

      Very severe with acute onset (thunderclap headache)
      Persistent (> 4 weeks) headaches that wake a child from sleep
      Persistent (>4 weeks) headaches that occur on waking
      Persistent (>4 weeks) headaches at any time in a child younger than 4 years
      Confusion or disorientation and a headache
      Vomiting and / or nausea on awakening for > 2 weeks
      Visual abnormality persisting > 2 weeks
      Motor abnormality (even if resolved)
      Regression in motor skills, Focal motor weakness, Abnormal gait and / or co-
      ordination (unless local cause), Bells palsy with no improvement within 4 weeks,
      Swallowing difficulties (unless local cause)
      Any combination of growth failure, delayed / arrested puberty and polyuria /
      polydipsia
      Behavioural change

II.   Examination
      Examination should include a full general examination (including vital signs). Look
      carefully at the head and neck region looking for local causes. Look for peripheral
      stigmata. Clearly a detailed neurological examination is essential, including head
      circumference in infants. Remember the importance of detailed visual assessment. If
      unable or difficult consider referral to ophthalmology.

B.   INVESTIGATIONS
     Neuroimaging
     • Consider urgent (within 48 hours) neuroimaging if any of the red flag symptoms or
       signs are present.
        Also consider in the following;
     - Headache in immunocompromised
     - Headache with suspected or known metastatic malignancy

CAEC Registration Identifier: 1703             Sheffield Children’s (NHS) Foundation Trust
                                          Headaches
     - Suspected ventriculoperitoneal shunt infection / malfunction

     • Investigation of choice is usually non-contrast CT as this is quick and easy. A
       contrast CT / MRI may be needed depending on differential diagnosis and following
       discussion with a radiologist.
     • Neuroimaging for headaches with no red flag symptoms is usually not needed.
       However please discuss non urgent neuroimaging with radiologist +/- neurologist if
       being considered.

     Lumbar Puncture
     To be performed in all cases of suspected meningitis. Be aware of contraindications
     (see below). May be appropriate to perform neuroimaging first. Remember to check
     opening pressures.
     Relative contra-Indications for LP; clinically unwell / unstable, prolonged / focal seizure,
     focal neurological signs, low GCS, suspected raised ICP (unless BIH), bleeding
     disorder.
     Other Tests (to consider, depending on differential diagnosis)
     Bloods – FBC / coagulation / U&E / LFT / CRP / bone profile / cultures / capillary gas
     (look at CO, but don’t be reassured if normal, if possibility get home boilers checked).

C.   TREATMENTS
     Clearly treatment will depend on the cause. Describing the management of all causes
     is beyond the scope of this guideline. Please consult medical literature / relevant
     specialities for further advice. This guideline will focus on the management of primary
     headaches mainly.

     General management
        Explanation of likely diagnosis and reassurance that no evidence of other pathology

        Recognise the impact the headache has on the patient and their family/carers

        Discuss management options including:
            o Non pharmacological; good sleep habits & routine, good fluid intake, regular
                meals, eliminate precipitants/trial of migraine elimination diet (avoiding
                sugary snacks, chocolate, cheese, baked beans, tomatoes, citrus fruits, fizzy
                drinks, caffeine, alcohol), regular exercise, eliminate/manage stressors
            o Pharmacological

        Provide information about headache disorders and support organisations eg The
         Migraine Trust website

        Explain the risk of medication overuse headaches
