Headache prevalence in the population of L’Aquila (Italy) after the 2009 earthquake.

"Stress induced by the events of daily life is. considered a major factor in pathogenesis of primary tension-. type headache. Little is known about the impact that. could have a more stressful event, like a natural disaster,. both in patients with chronic headache, both in people that. do not had headache previously. The aim of the present. study was to observe the prevalence of headache in the. population following the devastating earthquake that. affected the province of L’Aquila on April 6, 2009. The. study population was conducted in four tent cities (Onna,. Bazzano, Tempera-St. Biagio, Paganica). Sanitary access is. recorded in the registers of medical triage, in the first. 5 weeks, after the April 6, 2009. The prevalence of primary. headache presentation was 5.53% (95% CI 4.2–7.1), secondary. headache was 2.82% (95% CI 1.9–4.9). Pain. intensity, assessed by Numerical Rating Scale score. showed a mean value of 7 ± 1.1 (range 4–10). The drugs. most used were the NSAIDs (46%) and paracetamol. (36%), for impossibility of finding causal drugs. This study. shows how more stressful events not only have an important. role in determining acute exacerbation of chronic headache, but probably also play a pathogenic role in the. emergence of primary headache. Also underlines the lack. of diagnostic guidelines or operating protocols to early. identify and treat headache in the emergency settings."
