Parkinson's DIsease

Parkinson's Disease (PD) is a long-term degenerative disorder of the central nervous system that mainly affects the motor system. The symptoms generally come on slowly over time. Early in the disease, the most obvious are shaking, rigidity, slowness of movement, and difficulty with walking. Doctors do not know what causes it and finds difficulty in early diagnosing the presence of Parkinson’s disease. An artificial neural network system with back propagation algorithm is presented in this paper for helping doctors in identifying (...) PD. Previous research with regards to predict the presence of the PD has shown accuracy rates up to 93% [1]; however, accuracy of prediction for small classes is reduced. The proposed design of the neural network system causes a significant increase of robustness. It is also has shown that networks recognition rates reached 100%. (shrink)

This chapter discusses several kinds of reduction that are often found in the biomedical sciences, in contrast to reduction in fields such as physics. This includes reduction as a methodological assumption for how to investigate phenomena like complex diseases, and reduction as a conceptual tool for relating distinct models of the same phenomenon. The case of Parkinson’s disease illustrates a wide variety of ways in which reductionism is an important tool in medicine.

I am a philosopher with Parkinson’s Disease. Over the past several years I’ve been trying to write about my situation. I wrote about how I was forced to face the disease. I described how the disease twists and distorts my world. Then I asked myself, as a philosophy writer and teacher, whether I could say anything that might help myself or others facing life with Parkinson’s? I found ideas in the ancient Stoics and expanded them with ideas about time, coming (...) up with suggestions for living as excellently as possible despite the disease. Looking at those suggestions, I realized how the special awareness, resolve, and attention I was suggesting would be eaten away by dementia, and I know that a majority of Parkinson’s patients face dementia if they survive long enough. What can philosophy say to me or any person whose self and philosophy are being erased? Writing about such issues has helped me deal with my situation, and maybe my essay might be useful for others dealing with decline. (shrink)
