On the contribution of unconscious processes to implicit anosognosia.

Mograbi and Morris present a review of the literature on anosognosia of hemiplegia and dementia, including Alzheimer's disease. Their review focuses on aspects of implicit anosognosia. The authors' viewpoint is supported by the presentation of a general model on implicit anosognosia in Alzheimer's disease. The notions have important implications for clinical management, in particular, failure of treatment in Alzheimer's patients.
