Headaches in children and adolescents. An etiopathogenic classification

Headache is one of the most frequent reasons for presenting to Neuropaediatric units. Although in most cases the patient is not suffering from any serious disease, the parents and even the paediatrician do tend to fear that this is indeed the case. Evaluating a patient with headache requires a detailed interview as well as a careful clinico-neurological examination. From these elements it is basically possible to sort headaches into four large groups: acute, acute-recurrent, chronic non-progressive and chronic progressive. Acute headaches are an emergency and it is therefore necessary to have an algorithm available which can be used regardless of the degree of complexity of the clinical environment in which the patient is being treated. Invasive studies such as a spinal tap and/or neuroradiological studies are often needed. The International Headache Society criteria have been adapted to the juvenile population for the diagnosis of patients suffering from acute-recurrent headaches (migraine). Chronic non-progressive headaches are a group in which prevalence increases with age and is the most frequently observed form of headache in adolescents. Emotional factors, situations involving family and/or social conflict, either alone or in combination, are usually predisposing or triggering factors in this type of headache. Chronic progressive headache is a consequence of some organic disorder. In the search for and treatment of headache we must not forget to calm the pain experienced by the patient.
