Awareness and knowing: Implications for rehabilitation

Abstract

It has been known for well over a century that brain-damaged patients are often unaware of the very deficits that impair performance in everyday life. Pathologies of awareness have been described for many neurological, psychiatric and neuropsychological deficits and the construct of “awareness” or “insight” understandably now receives attention from many researchers within the clinical and cognitive neurosciences. This paper does not attempt to explain the nature of consciousness or its impairment but rather considers four aspects of consciousness/awareness that health care professionals interested in understanding, measuring and improving deficits of awareness should consider.
