Abstract:
In order to study the type and cerebral location of agnosia in patients with cerebral vascular disease, 35 patients with single cerebral lesion determined by CT or MRI were checked. The standardized Aphasia Battery in Chinese and self designed tasks about agnosia were adopted. The results showed that there were object agnosia, picture agnosia, color agnosia, agnosia acalculia, auditory agnosia, tactile agnosia, neglect, environmental agnosia, body agnosia in left hemisphere group, and color agnosia, neglect, environmental agnosia, anosognosia in right group. The conclusions were that for the majority of dextrals, cerebral dominance for visual, auditory, tactile, body cognition all located in the left hemisphere. Color agnosia may happen in right hemisphere. Either hemisphere can produce neglect, anosognosia, and the incidence in right hemisphere is higher than in left one.
