I am about start a project on computational modelling of basal ganglia in the context of motor problems in Parkinson's disease. My background is mostly on computational side (and some neuroscience too) and I know relatively little about medicine. So I would like to extend my knowledge of the Parkinson-related medical science, so that I see not only separate puzzle pieces.
Could somebody suggest a recent book on Parkinsons's disease from medical perspective (and the more fundamental systems neuroscience it contains, the better)? I am more interested in motor symptoms and cognitive problems, as well as their treatments. To emphasize, I am NOT looking for a book on computational approaches to BG/Parkinson's, I really want to know what neurologists think.
I have already posted this question on medical SE but I was redirected here.
