Facial agnosia in the clinical presentations of brain lesions

Abstract

Facial agnosia (prosopagnosia) is one of the causes of limitations in the life of patients with focal vascular, inflammatory, traumatic, and tumor lesions of the brain; however, the clinical significance of these lesions in neurological practice is often underestimated.The review briefly presents the current understanding of the neurophysiological basis of facial gnosis and its neuroanatomic correlates. It discusses the clinical variants of prosopagnosia, the features of neuropsychological diagnosis, and adopted approaches to patient rehabilitation. It also highlights the importance of developing standardized methods for facial agnosia to improve the detection of prosopagnosia in focal brain lesions.
