Symptoms Of Progressive Supranuclear Palsy

Photophobia

Another common symptom of PSP, as the disease progresses, is photophobia. Photophobia is the experience of discomfort or pain to the eyes due to light exposure or due to the presence of actual physical sensitivity of the eyes. In relation to PSP, a clinical study was performed on 187 patients, which concluded that forty-three percent of these patients showed symptoms of photophobia. Another study showed that photophobia is significantly greater in clinically diagnosed PSP than in corticobasal degeneration (CBD), which is a progressive neurological disorder that is characterized by nerve cell loss and atrophy of multiple parts of the brain. These study results can help doctors differentiate between both of these diseases due to the presence of photophobia.
