Visual Hallucinations and Parkinson's Disease

Studies are now being conducted concerning hallucinations that correspond to having Parkinson's disease. Multiple aspects of brain function are affected with this disease. Subjects that displayed the worst symptoms were those with the worst cases of Parkinson's and those that were older. It was important in this study to find the similarities between a "normal" Parkinson's patient and a patient that had hallucinations to see if the same areas of the brain were affected. This is interesting because Parkinson's disease usually affects motor skills to the greatest extent, now it is found to be affecting visual capacities.
