Toward a More Inclusive Definition of Brain Health

Our fate and the world's hinges on our brains. As the mediator of all our experiences and motor of all our actions, the brain's state and performance become paramount in an increasingly complex world. This is reflected in the expanding interest in "brain health." However, "brain health" is defined in many ways or not at all but used with profligate ease. We need to anchor the multiple definitions to a common, comprehensive, and comprehensible definition.
