Warning Symptoms Of Posterior Cortical Atrophy

Sensitivity To Light

Sensitivity to light is another early symptom of posterior cortical atrophy. In the beginning, patients may be more sensitive to bright lights, including flashlights, lights in the bathroom, and bright sunlight. Doctors can evaluate the degree of a patient's sensitivity to light with a comprehensive eye exam. As posterior cortical atrophy advances, patients may have a reduced tolerance for other types of light that are not particularly bright. For some individuals, light sensitivity may be accompanied by headaches. To reduce this sensitivity, patients may wish to wear sunglasses (both outdoors and inside the home), and they might want to install lights with dimmer systems to adjust brightness. Curtains may be helpful as well. In addition to light, some patients may be sensitive to shiny objects, and choosing items with a matte finish may be beneficial.
