After suffering from a focal brain injury, a patient has difficulty in recognizing visually presented objects, despite normal acuity and color perception. Notably, she has severe difficulty in judging whether two pictures, each showing a different view, represent the same object. What is the most probable diagnosis?

B)associative visual agnosia
C)synesthesia
D)prosopagnosia

Question

Apperceptive visual agnosia is a type of visual agnosia that results from damage to the occipital and parietal lobes of the brain. Patients with this condition have difficulty in perceiving and recognizing objects due to a deficit in early visual processing. They may have normal visual acuity and color perception but struggle to match multiple views of the same object. This matches the symptoms described in the scenario. Associative visual agnosia, on the other hand, is characterized by a deficit in higher-level processing of visual information and difficulty in recognizing familiar objects despite intact perceptual abilities. Synesthesia is a condition in which stimulation of one sensory modality leads to automatic and involuntary experiences in another modality. Prosopagnosia is a condition in which the patient has difficulty in recognizing faces. None of these conditions match the symptoms described in the scenario as closely as apperceptive visual agnosia.
