Automatic, unsupervised classification of dyskinesia in patients with Parkinsons Disease
One of the characteristic symptoms of patients with Parkinson Disease (PD) is a rigidity of movement. These symptoms disappear after administration of Levodopa. However, the long-term use of levodopa causes involuntary movements (dyskinesia). A proper diagnosis requires an automatic, unsupervised method for the detection and classification of levodopa induced dyskinesia. The main problem, howev...
متن کاملChanging brain networks for visuomotor control with increased movement automaticity.
Learning a motor skill is associated with changes in patterns of brain activation with movement. Here we have further characterized these dynamics during fast (short-term) learning of a visuomotor skill using functional magnetic resonance imaging. Subjects (n = 15) were studied as they learned to visually track a moving target by varying the isometric force applied to a pressure plate held in t...
متن کاملEvaluation of Visual Signs and Symptoms in Patients with Alzheimer's Disease
Background and Objective:Patients with Alzheimer's disease have impaired visual function even in the early stages of the disease. Therefore, the present study aimed to determine the visual signs and symptoms in patients with Alzheimer's disease and compare them with those in the control group. Materials and Methods:This cross-sectional descriptive study was conducted on 19 Alzheimer patients a...
