The volunteer should make a survey of the health centers that exist in their municipality/district. Then, you should explain to the health centers the mission of Núcleo Cavernoma Portugal and the need to make known to the users of the health centers the dissemination of the disease - cerebral and medullary cavernomas - which is a disease of the central nervous system. The Executive Board of Núcleo Cavernoma Portugal prepares the action of the volunteers before they start the task. View the site - www.cavernomaportugal.pt
