Agnosia (C0001816)

Definition (NCI) A rare disorder characterized by the lack of ability to recognize individuals, objects, shapes, sounds, or smells. There is no loss of memory. It is caused by neurological damage in the brain, specifically in the occipital or parietal lobes.
Definition (MSH) Loss of the ability to comprehend the meaning or recognize the importance of various forms of stimulation that cannot be attributed to impairment of a primary sensory modality. Tactile agnosia is characterized by an inability to perceive the shape and nature of an object by touch alone, despite unimpaired sensation to light touch, position, and other primary sensory modalities.
Definition (PSY) Inability to recognize, understand, or interpret sensory stimuli in the absence of sensory defects. Also, the selective loss of knowledge of specific objects due to emotional disturbance, as seen in schizophrenia, hysteria, or depression.
Definition (CSP) loss of the ability to distinguish the significance of stimuli; may be auditory, visual, olfactory, tactile, or gustatory.
