INTRODUCTION: Headache disorders are a common cause of medical consultation among adolescents and young adults. Proper diagnosis and management of headache in young age, depends on taking through history and comprehensive clinical examination. We aim to analyse characteristics of young patients attended in an outpatient headache clinic in a tertiary hospital, and incidence of their different headaches codified according to International Classification of Headache Disorders, II Edition (ICHD-II)
METHODS: Due to our health system organization, only patients older than 14 years were referred to this office, most of them by general practitioners. From January 2008 to December 2011, we prospectively gathered in each patient gender, complementary tests required, and previous symptomatic or prophylactic therapies. When a patient fulfilled criteria for more than one type of headache, all of them were diagnosed and classified. We measured adverse headache impact with six-item Headache Impact Test (HIT-6)
RESULTS: 1668 patients were attended during inclusion period. 208 (12.5%, 55 males, 153 females) were younger than 25 years. 201 (96.6%) had received at least one symptomatic treatment, but only 93 (44.7%) had previously used a preventative. 141 (67.8%) did not required ancillary tests. A total of 297 headaches were recorded in these 208 patients. Only 19 (6.4%) were secondary headaches, and most of them were codified in Group 8 (Headache attributed to a substance or its withdrawal). Regarding primary headaches, 215 (72.4% of all headaches) were in Group 1 (Migraine), 19 (6.4%) in Group 2 (Tension-type), 3 (1%) in Group 3 (Trigeminal autonomic), and 16 (5.4%) in Group 4 (Other primary headaches). One (0.3%) was classified as Group 13 of ICHD-II (Cranial neuralgias) and only 2 (0.7%) headaches corresponded to Group 14 (Unspecified or not elsewhere classified headaches). In 114 patients (54.8%) HIT-6 score showed a severe impact (>59)
CONCLUSION: Most headaches in young age can be codified according to ICHD-II criteria. Migraine was the most frequent diagnosis. Headache was commonly associated with negative impact among young patients. We suggest preventatives to be more widely used by general practitioners in young age.
