Cerebral achromatopsia is a type of color-blindness that is caused by damage to the cerebral cortex of the brain, rather than abnormalities in the cells of the eye`s retina. It is often confused with congenital achromatopsia. Cerebral achromatopsia differs because it is caused only by trauma or brain damage. The symptoms of both cerebral and congenital achromatopsia are similar but not identical, and their causes are widely different.
