Changes in the visual systems of newly diagnosed Parkinson’s disease patients may provide important biomarkers for the early detection and monitoring of the disease, according to a new study published online in the journal Radiology<\/em>.<\/p>\n

Parkinson’s disease is a neurodegenerative condition caused by neuronal loss in several brain structures. Parkinson’s disease is characterized by tremors, rigidity or stiffness throughout the body, and impaired balance and coordination. However, non-motor symptoms across all stages of the disease are common, although they tend to be undiagnosed and under-treated since patients are not aware of the link.<\/p>\n

Non-motor symptoms experienced by patients with Parkinson’s disease include visual alterations such as an inability to perceive colors, a change in visual acuity, and a decrease in blinking which can lead to dry eye and can precede the appearance of motor symptoms by more than a decade, according to the researchers.<\/p>\n

The study compared 20 newly diagnosed and not yet treated patients with Parkinson’s disease and 20 age- and gender-matched healthy controls. The researchers found significant abnormalities within the visual system brain structures of Parkinson’s disease patients, including alterations of optic radiations, a reduction of white matter concentration and a reduction of optic chiasm volume. The optic chiasm is the part of the brain where the left and right optic nerves intersect.<\/p>\n

Researchers hope that the in-depth study of visual symptoms may provide more sensitive markers of Parkinson\u2019s disease and help differentiate Parkinsonism disorders, follow disease progression and monitor patient response to treatments.<\/p>\n
