Warning Signs Of Creutzfeldt-Jakob Disease

Vision Problems

In addition to causing fast-acting dementia, Creutzfeldt-Jakob disease damages the eyes. The patient will experience double vision and hallucinations, and they will eventually go blind. In the Heidenhain variant of Creutzfeldt-Jakob disease, vision problems are the first symptom to develop. In addition to hallucinations, vision problems can include the distorted perception of structures and colors, visual anosognosia, and cortical blindness. Many of the vision problems, like cortical blindness and visual anosognosia, are caused by damage to the brain’s occipital lobe. In fact, much of the brain damage in the Heidenhain variant is concentrated in the occipital lobe. Patients with the Heidenhain variant of CJD generally start displaying other symptoms days or weeks after their vision problems have appeared. Like other types of Creutzfeldt-Jakob disease, the disease progresses rapidly.
