A cefaléia tipo tensão em suas duas modalidades, episódica e crônica, é a forma mais comum de dor de cabeça na população. O tratamento é feito com medidas não farmacológicas e farmacológicas, tanto para o ataque como profilaxia das crises. Este estudo foi realizado com 5490 pacientes, que procuraram ambulatórios e consultórios médicos em várias regiões do Brasil. Cerca de 95% apresentavam cefaléia tipo tensão episódica e 5% cefaléia tipo tensão crônica. A maioria dos pacientes apresentou crises de intensidade moderada (62,19%). Em 5419 pacientes uma crise de cefaléia tipo tensão foi tratada com 1000 mg de paracetamol e 130 mg de cafeína. Em 93,98% início de melhora foi observado em até 2 horas após a ingestão da medicação. Em 77,61% houve reversão completa da crise em até 2 horas. Avaliação da eficácia boa/excelente foi observada em 51,93%/37,80% dos casos quando feita pelos médicos e em 48,51%/40,29 quando pelos pacientes. Efeitos adversos, em geral manifestações gastrointestinais, foram observados em 5,57%. Este estudo representa uma experiência brasileira no tratamento de ataque da cefaléia tipo tensão, demonstrando eficácia e segurança no uso da combinação paracetamol-cafeína.<br>Tension type headache in both its forms, episodic and chronic, is the most common type of headache experienced by the population.

Latin American consensus on guidelines for chronic migraine treatment

Chronic migraine is a condition with significant prevalence all around the world and high socioeconomic impact, and its handling has been challenging neurologists. Developments for understanding its mechanisms and associated conditions, as well as that of new therapies, have been quick and important, a fact which has motivated the Latin American and Brazilian Headache Societies to prepare the present consensus. The treatment of chronic migraine should always be preceded by a careful diagnosis review; the detection of possible worsening factors and associated conditions; the stratification of seriousness/impossibility to treat; and monitoring establishment, with a pain diary.
