Infos

This text provides an overview of the processes of brain death, exploring the concepts and historical approach of human death, clinical examinations of brain-dead patients, ancillary tests in coma and brain death, bioethical discussions of brain death and its relationship with some consciousness disturbances, and the legal considerations of human death. Unlike other, narrow-focus reference this book encompasses a wide spectrum of issues including medical, legal, bioethical and historical aspects.
