Traditionally the International Congress of Parkinson's Disease and Related disorders (ICPD) is reflected in publishing its proceedings. This is to (1) sum up the current knowledge in this particular spectrum disorder and (2) to remind clinicians and basic researchers on the development and progress made overtime with respect to etiology, pathology, genetics, endogenous vulnerability factors, models, drug treatment strategies, e.g. levodopa, neuroprotective drugs, new developments in neurotherapeutics, neurosurgery, plasticity of nerve cell structures and clinical issues (e.g. staging, early diagnosis, differential diagnostic aspects, clinico-pathological correlations, new scales etc.). All these topics that have been brought forward at the 16. ICPD congress 2005, Berlin, are now available in a subsumed version in supplementum 70 of Journal Neural Transmission.

This book gives a comprehensive overview on current clinical and basic research issues related to Parkinson's disease and its related disorders and is suitable for neurologists, psychiatrists, neurosurgeons, basic researchers, geneticists and patients as well as their relatives.
