title: [Challenges of bioethics in twenty-first century medicine].
abstract: In order to propose possible challenges of bioethics in the twenty-first century medicine, it is necessary to consider that there were some past challenges (at the origin of this new discipline called bioethics), that the challenges have been modified with scientific, biomedical and humanistic breakthroughs, considering at the same time that challenges that may arise in the future will be, in different ways, a result of this historical evolution. The major challenges would be in the future: the unsolved problems of justice, equity and poverty; the challenges posed by the introduction of new technologies with the nanomedicine paradigm; and finally, the challenges driven by breakthroughs in neurosciences with the neuroethics paradigm.
