visual agnosia
cannot recognize objects
Visual agnosia is a type of neurological disorder where an individual can see objects but is unable to recognize them, despite having intact vision and comprehension abilities. This is caused by damage to the posterior part of the brain, specifically the occipital and temporal lobes.
There are different types of visual agnosia including apperceptive agnosia, associative agnosia, and prosopagnosia. Apperceptive agnosia affects the individual’s ability to perceive objects, making it difficult for them to copy or match shapes. Associative agnosia affects the ability to recognize the function or purpose of an object. People with prosopagnosia have difficulty recognizing faces and are unable to differentiate between people they know.
Treatment for visual agnosia largely involves rehabilitation, cognitive therapy and visual training. In cognitive therapy, patients are taught compensatory strategies to improve their visual recognition ability. In visual training, patients work on exercises to train their brain to recognize objects. However, the success of treatment strategies depends on the severity of visual agnosia and the extent of damage to the brain.
