Visual agnosia refers to the impaired ability to identify visual objects despite otherwise satisfactory vision. It is the inability to recognize a person or object by sight. Moreover, Visual agnosia is an impairment of visual object recognition in brain damaged individuals who possess basic visual abilities and reasonable knowledge about objects.
There are two (2) forms of Visual agnosia:
(1) Apperceptive agnosia. Object recognition is impaired because of deficits in perceptual processing; and
(2) Associative agnosia.
Perceptual processes are essentially intact, but object recognition is imapired partly or mainly because of difficulties in accessing relevant knowledge about objects from memory.
