How is breath-holding diagnosed?
To diagnose breath-holding, your child may undergo a thorough medical and physical examination to ensure they do not have any underlying medical problems such as a heart condition. Your doctor may ask you about the skin colour your child has during breath-holding spells, changes in body tone, how often the episodes occur, how long the child is unconscious for, and the events that precede and follow the spells. For more frequent episodes, laboratory tests may include electrocardiography, to assess heart function or electroencephalography, and to examine brain activity. your doctor may order blood tests to rule out iron-deficiency anaemia.
