See also astereognosis.time agnosia loss of comprehension of the succession and duration of events.visual agnosia inability to recognize familiar objects by sight, usually due to a lesion in one of the visual association areas. Called also object blindness and psychic blindness.visual-spatial agnosia (visuospatial agnosia) lack of the ability to analyze and orient using visual representations and their spatial relationships.ag·no·si·a (ag-nō'zē-ă), Impairment of the ability to recognize, or comprehend the meaning of, various sensory stimuli, not attributable to disorders of the primary receptors or general intellect; agnosias are receptive defects caused by lesions in various portions of the cerebrum.

Loss of the ability to interpret sensory stimuli, such as sounds or images.Agnosia An inability to recognise sensory stimuli (objects, people, sounds, shapes or smells) in absence of a destruction of neural pathways. Agnosias are common in parietal lobe tumours, and are classified according to the sense affected—e.g., touch (tactile agnosia), hearing (auditory agnosia), sight (visual agnosia), smell (olfactory agnosia), or taste (gustatory agnosia).agnosia Neurology An inability to recognize sensory stimuli–objects, people, sounds, shapes or smells, common in parietal lobe tumors; agnosias are classified according to the sense affected–eg, touch–tactile agnosia, hearing—auditory agnosia, sight—visual agnosia, smell–olfactory agnosia, taste–gustatory agnosia.

[G. ignorance; from a- priv. + gnōsis, knowledge]agnosia A disorder of the ‘association’ areas of the brain, in which the person cannot correctly interpret sensory input. Agnosia commonly follows STROKE.agnosia Inability to recognize the import of sensory stimuli (e.g. to recognize colour, faces, shape and the orientation of objects), although the receptors and the sensory pathway are intact. The condition is attributed to bilateral lesions in the association areas of the cortex. If the sense of sight is affected, it is called visual agnosia (perceptual or psychic blindness).
