Neurologic syndromes in which there is impaired deficit-awareness (termed "anosognosia") provide useful observations for understanding the nature of metacognition and its neurobiologic correlates. Anosognosia can occur in various disorders, including stroke, head injury, particular amnesic syndromes, and various dementing illnesses (e.g., Alzheimer's disease). Research on anosognosia for memory impairment is important both for its clinical implications and for its contributions toward understanding the neural correlates of, and processes by which, persons are aware of, monitor, and develop beliefs about their own memory functioning (i.e., metamemory). Following a brief introduction to anosognosia, a review is provided of research on awareness of memory deficit in persons with neurologic amnesia or dementia syndromes. Particular emphasis is placed upon the examination of how different experimental methods shed light on specific questions about metamemory impairment.
