ABSTRACT

La fisiopatología de las cefaleas primarias es compleja e incluye un sinnúmerode interacciones que regulan el proceso nociceptivo. Dentro de los principalesresponsables de generar el dolor se encuentra el sistema trigémino vascular, que esun conjunto de estructuras que integran vías tanto centrales corticosubcorticales comoperiféricas, que desempeñan un papel activo no solo en la génesis del dolor, sino enlas manifestaciones autonómicas y visuales que acompañan la cefalea. Así mismo, estesistema es el responsable de los mecanismos de sensibilización central característicosdel dolor. En el artículo se desarrollan brevemente las principales estructuras queparticipan en la génesis de las cefaleas primarias y sus interacciones en las diferentespartes del sistema nervioso...


The pathophysiology of primary headache iscomplex and it includes several interactionsthat regulate the nociceptive process. The trigeminal-vascular system is perhaps one of theprincipal structures that generate pain due tothe integration of several pathways both centraland peripheral. In addition to this, the trigeminalvascular system also plays a central role inthe autonomic and visual symptoms that affectindividuals with headache and in the centralsensitization process. In this article we brieflydiscuss the main structures that participate in thepathophysiology of primary headaches and theirinteractions in the different levels of the centralnervous system...

ABSTRACT

As cefaléias são dores que assumem características clínicas, genéticas, fisiopatológicas e terapêuticas que as distinguem fundamentalmente das demais dores do ser humano. Dividem-se entre dores primárias ? as mais freqüentes ? e secundárias, de acordo com a presença ou não de desordens causadoras subjacentes. Nesta revisão salientamos os principais aspectos das cefaléias raras listadas pela Classificação Internacional das Cefaléias e que incluem: a hemicrania paroxística, SUNCT/SUNA, cefaléia primária em facadas, cefaléia primária da tosse, cefaléia primária do exercício, cefaléia primária associada à atividade sexual, cefaléia hípnica, cefaléia em trovoada, hemicrania contínua e a cefaléia nova diária e persistente. O diagnóstico depende da colheita de uma história cuidadosa e atenta, posto que reside no quadro clínico a chave para o diagnóstico diferencial.


Headaches are conditions fundamentally distinct from pain elsewhere due to clinical, genetic, pathophysiological and therapeutic reasons. They are first and foremost divided into primary - much more common - and secondary diseases according to the presence of underlying causes. In this short review, we highlight the most characteristic of the relatively rare primary headaches listed in the HIS Cassification of Headache Disorders, including proxysmal hemicrania, SUNCT/SUNA, pimary stabbing headache, pimary cough headache, pimary exertional headache, pimary sexual headache, hpnic headache, rimary thunderclap headache, hemicrania continua and new daily persistent headache. Diagnosis depends on a comprehensive case history, as the clue for differentiation among such conditions reside on clinical grounds.
