The Clinical Pathology of Parkinson’s Disease
The symptoms of Parkinson’s disease include tremor and rigidity, both positive motor symptoms, and akinesia. Akinesia can be thought of as a negative symptom, being characterized by the inability to convert a potential for movement into kinetic energy (Birkmayer 1965), while tremor is due to the emergence of a primitive pattern of motor behaviour and rigidity results from current stimulatory and inhibitory neuromuscular activity.
