[Higher visual disorders].

Higher visual disorders as discussed in this paper comprise visual hallucinations, palinopsy, hemineglect, Balint Holmes syndrome, prosopagnosia, visual objectagnosia, alexia without agraphia and cerebral achromatopsia. Such disorders are frequently caused by ischemia, but tumors, trauma and intoxication are possible as well. As a rule, higher visual disorders are a transient phenomenon. It is important to inform the patient and his family about the nature of the disorder and consider persisting disorders during rehabilitation.
