Ethics and

Brain Injury

Brain injury is an international health problem that places a significant burden on patients, their families, and health care systems. Globally, it is estimated that 50-60 million traumatic brain injury cases occur annually. In the U.S., it is estimated that 3.5 million traumatic brain injuries occur per year with an annual cost burden of at least $76.5 billion. Improvements in neurocritical care have increased survival rates following severe brain injury, but outcome remains variable. Following a period of coma, some patients make a good recovery, while others progress into a vegetative state, minimally conscious state, or die. Diagnosis is difficult and errors occur often. Advancements in functional magnetic resonance imaging  and electroencephalography  can provide a solution. These technologies can improve the accuracy of diagnosis and could revolutionize our understanding of severe brain injury and the nature of human consciousness. Yet the use of these technologies also raises complex ethical and policy issues. This project seeks to investigate ethical and policy issues in the use of functional neuroimaging and electroencephalography to assess brain-injured patients. This project builds upon a Canadian Institutes for Health Research-funded project entitled, The Ethics of Neuroimaging after Serious Brain Injury.
