As our bodies use the sugars that we consume for energy they generate waste chemicals known as metabolites. One such group of metabolites is known as advanced glycation end products or AGEs for short. Critically apart from their production as a result of sugar breakdown, AGE levels in the body are also increased by the foods that we eat and when we do not get enough exercise. AGEs may cause many of the side effects experienced by prostate cancer survivors. This study aims to examine the effects of diet change and exercise on AGE levels in prostate cancer survivors.
We will ask 80 patients with Parkinson's disease, representing the full spectrum of motor and cognitive symptoms, to participate. Participation will include measurement of eye movements using two methods: the new computer-based saccade battery and the best available video-based eye-tracking equipment. The evaluation will be repeated about 30 days later. Data will be analyzed to determine whether the computer-based tasks are reliable and able to provide the same quality of information as the gold standard in eye-tracking. A comparison sample of 80 healthy older adults will also complete the behavioral saccade tests in order to establish normative data that will enable application in clinical settings.
