Semantic Aphasia: A Neglected Entity
Three Cases of Semantic Aphasia Are Reported. Computerized Brain Tomography Showed Bilateral Temporo-Parieto-Occipital Junction Hemorrhages in One Patient, and Left Parieto-Occipital Junction Infarctions in the Other Two Patients. the Auditory Comprehension Defect of the Three Patients Was Characterized by Preserved Understanding of Single Words and Impaired Understanding of Grammatically Complex Constructions. It is Suggested that This Comprehension Defect Reflects an Inability to Fully Grasp the Meaning of Words and Grammatical Constructions Imbued with Spatial or Quasi-Spatial Significance. Each of the Three Patients Showed a Complex Spatial Disorder that Included Constructional Apraxia, Spatial Agnosia, and Elements of Gerstmann's Syndrome. the Aphasic as Well as the Spatial Disorder of Semantic Aphasics May Be Manifestations of a Common Defect in the Perception of Spatial Relationships Produced by Left Temporo-Parieto-Occipital Region Damage. © 1980.
