Impaired+Color+Recognition

In this condition, although sometimes able to correctly name objects patients cannot correctly name, match, and identify colors or point to colors named by the examiner. This is not due to color blindness. Frequently individuals with color imperception also display prosopanosia.

DeRenzi & Spinnler (1967) found that 23% of those with right cerebral damaged and 12% of those with left sided destruction had difficulty with color matching. On the otherhand, some investigators note that impairments of color perception are frequently secondary to bilateral inferior occiptial lobe damage. In addition, almost 50% of those with aphasia demonstrate deficient color naming and color identification. However, color perception per se is largely intact among aphasic individuals.
