Pathophysiologic Basis of Movement Disorders.

Pathophysiologic Basis of Movement Disorders. Prog Neurol Surg. 2018;33:13-24 Authors: Wichmann T Abstract Movement disorders are common and functionally disabling neurologic diseases. Studies over the last decades have investigated the pathophysiology of these diseases in considerable detail, leading to significant insights into their generation of motor disability. While genetically and clinically heterogeneous, most of them are accompanied by prominent and characteristic changes in firing rates and patterns in the basal ganglia, thalamus, and cortex. In recent years, researchers have placed increasing emphasis on the importance of oscillatory changes in firing in these structures, and have discovered that brain areas that were previously considered to be remote from the basal ganglia (such as the cerebellum and the pedunculopontine nucleus) are also highly significant in these disorders. The evolving pathophysiologic concepts have important implications for improving our understanding of the biology of these disorders, and for the development of more effective pharmacologic and surgical therapies with fewer side effects than seen with the currently available treatments. In this chapter, the known pathophysiology of three common movement disorders, Parkinson's disease, dystonia, and essential tremor, is reviewed. PMID: 29332070 [PubMed - in process]
