Abstract
There are several points where ethical decision-making has become paralyzed and inefficient as the field of Alzheimer's disease study has advanced. The focus of this review is to highlight these points and several lines of research that can inform ethical decision-making. The goal is to identify barriers and to move toward solutions. Examples of other fields of study that can be particularly useful for innovative ways to study effective ethical decision-making include implementation science and neuroscience of decision-making, as well as therapeutic investigations of other domains such as the human biology and psychology.
