Differential diagnosis

  • A full history and physical examination are necessary. Referral to specialist paediatric services will be required when indicated medically, in protracted cases and in severely impaired children.
  • Investigations are as for adult guidelines, to exclude an explanatory medical disorder. For example, investigations for chronic fatigue should include full blood count, CRP (or ESR), thyroid function tests, urea and electrolytes, blood sugar and liver function tests, tests for glandular fever. If clinically indicated, screening for gluten-sensitive enteropathy or autoimmune disease might be helpful.]
  • School phobia (phobic anxiety disorder).
  • Generalized anxiety - F41.1 (adult) and/or Panic disorder - F41.0 (adult)
  • Depressive disorder- F32#
  • Eating disorders - F50
