A multidisciplinary survey of the progress in research on CNS trace amines. The profound pharmacological, physiological, and behavioural effects of these endogenous substances, effects whose proper understanding is rapidly emerging as a result of strong methodological advances, promises great progress in the clinical treatment of psychiatric and neurological disorders. This work should be of interest to all experimental and clinical neuroscientists.

A probable neurobiological role for the trace amines began to emerge as soon as techniques sufficiently sophisticated to detect them were developed. Techniques for quantitative analyses included radioenzymatic procedures and, more recently, HPlC-EC and auto­ mated GC-MS. The methods are applied after separation of the sub­ stances to be analyzed and after their purification by physicochemical procedures that are becoming more and more efficient. The identification and quantitative analysis of minute amounts of trace amines in biological fluids or tissues is in itself a remarkable technological achievement. The enormous task that several teams of research workers have set themselves is to investigate the origin of the trace amines, to understand their metabolism, and to discover whether or not they possess an important biological role. The 2nd Trace Amines Symposium at Weitenburg Castle near Tubingen from the 15th to the 19th May 1985 was held to gain a somewhat clearer insight into the present state of knowledge. Since the first meeting in 1983 our knowledge has increased and interest is deepening. Hence the idea proposed at that first meeting, of organizing similar gather­ ings at regular intervals, has come to fruition. Covered in the Neuropsychopharmacology section of this book are studiesof the effects of certain trace amines on different forms of be­ havior, on neurotransmission mediated by . the classical neuro­ transmitters, on their biosynthesis or on catabolism, on their possible occurrence as a result of alternative metabolic pathways for the amino acids, and in some instances their neuroanatomical distributions.

Volume 5 of the series "Advances in Research on Neurodegeneration" is concerned with themes which are currently the focus of intensive research, and in which advances in our understanding of the pathological mechanisms un­ derlying neurodegenerative diseases are expected in the near future. The first section contains five reviews devoted to the various neuroimaging technolo­ gies. The discussion is concerned with the question of whether neuroimaging techniques make it possible to follow the process of degeneration as it occurs, and which methods offer the required sensitivity and quantifiability for this purpose. However, the question needs to be examined of whether, given the physical and chemical limitations of these techniques, even under optimal conditions, anatomical resolution can be improved to the extent that neuro­ degenerative diseases can be diagnosed earlier than currently possible and a confident diagnosis made. The possibilities of using neuroimaging techniques to provide information regarding the effects of neuroprotective or neuroregen­ erative therapeutic strategies, and for correlating the results of neuropsycho­ logical research with imaging data are also discussed. The second section is concerned with the significance of endogenous or exogenous neurotoxins as triggers for neurodegenerative processes that may lead to Parkinsonism. Vulnerability factors, which include such factors as nerve ending sensitivity, the synergistic effects of drugs and the various mechanisms underlying different toxins are discussed.

Neurodegeneration is one of the most important subjects of the investigation now and in the coming 21st century. Alzheimer's disease is the leading cause of dementia in the elderly people and Parkinson's disease is one of the major neurologic disorders with the prevalence between 1 and 2/1 000 population in advanced countries. Many others are suffering from intractable neurodegener­ ative disorders such as amyotrophic lateral sclerosis, Huntington's disease, or spinocerebellar degeneration. No truly effective treatment is available for any of these neurodegenerative disorders except for Parkinson's disease; even in Parkinson's disease, still it is impossible to slow down the disease process with the currently available treatment. It is urgently needed to develop new effective technique to halt or slow down the disease process in each of those disorders. Recent advance in the molecular biological and molecular genetic technique has brought us great progress in the understanding of etiology and pathogenesis of these disorders, but still it is not known how neurons are going to die in these disorders. To explore the question, mutual cooperation and exchange of ideas between basic scientists and clinical peoples are of utmost importance.

The volume contains recent advances in research on neurodegeneration and neuroinflammation. Particular interest was focused on molecular biological aspects of the mechanism of neuronal death in neurodegenerative disorders, particularly Parkinson's disease, Alzheimer's disease, spinocerebellar degeneration and multiple sclerosis. International opinion leaders and top class researchers reviewed the progress in the above subjects. Future aspects of neuroprotection in neurodegenerative disorders and neuroinflammatory disorders were also discussed.

The 8th International Winter Conference on Neurodegeneration from Febru- ary 9 to 13, 2000 took place in Tegernsee, Bavaria, Germany. The interest shown in this symposium, which was carried by invited speakers only, was striking. 28 lectures in 5 sessions dealt with themes on basic science and therapy strategies for neurodegenerative illness. This time especially basic mechanism of cell death and resulting causal treatment possibilities were centre themes of the lectures and lively discussions. In accordance with tradi- tion 5 lectures on Multiple Sclerosis finished the convention. 60 scientists from 13 countries discussed current questions to these themes. The Symposium started with a lecture on the history of the develop- ment of modern-L-DOPA-therapy. Lectures on cell death of dopaminergic nerve cells, new valuation regarding assembly, built up and function of neuromelanin of Substantia nigra and with this, the question of the physio- logic and pathobiochemical role of dopamine and neuromelanin built the first block of themes which consequently extended to molecular and genetic aspects of cell death.Highlights of the symposium were neuroprotective and neuroregenerative future therapy strategies together with discussions on the difficulties of clinical neuroprotection. Developmental biological aspects on nerve cells, reorganisation and neurodegeneration showed a stimulating point of view of momentary and future development possibilities of new and more causal forms of therapy of neurodegenerative illness.

The 10th International Winter Conference on Neurodegeneration (lWCN) has taken place from February 14-16,2002, at the lovely "SchloB Ziethen", an old prussian manor (in Prussia, 'faute de mieux', called 'SchloB', i. e. cas- tle or residence). This place is 20 km off Tegel Airport, Berlin's main airport, and has been beautifully restored by baroness Edith von Thiingen (nee von BUlow, i. e. of historical Prussian aristocracy); it lends itself rather perfectly for the IWCN type of small interdisciplinary workshops on neurodegenera- tion which combine short lectures with plenty of discussion. In this context, we could quote Alexander von Humboldt's famous opening words for one of the first international scientific meetings held at Berlin, on September 18, 1828: "The main purpose ...does not consist in a mutual reading of manuscripts all to be printed after at least one year in specialised publications, but in the personal communication amongst those who work in similar scientific fields; the oral and thus more stimulating exchange of ideas, might they represent facts, opinions or doubts; the foundation of friendly relations which convey illumination to our sciences, serene grace to our lives and tolerance and mildness to our habits ...Berlin, Sept. 18, 1828 Alexander von Humboldt To the IWCN aficionado, it may come as a little surprise that this is the pub- lication of the 10th Winter Conference as this might mean that they must have missed number 9.

This volume contains the proceedings of the symposium Pathochemical Markers in Major Psychoses, held in Vienna in July 1983. The development of biological markers in psychiatric diseases, par­ ticularly in the field of neurochemistry, has made substantial progress during recent years although the multiple mechanisms of mental illness are still not fully understood. The greatest contribution has come through the development of new therapeutic agents that not only pro­ vide invaluable help for psychiatric patients but also serve as chemical tools for the investigation of the biological mechanisms underlying the disease. The catecholamine and serotonin hypotheses for major psy­ choses have been of particular heuristic value and have stimulated im­ portant research. However, the scope of our scientific endeavours has to be broadened to include other putative biological causes of psychoses, e. g. , pathomorphological changes, aberrations in the metabolism of other amino acids and oflipids, or the formation of endogenous toxins. This book presents new selected studies of the pathochemical bases of schizophrenia and affective psychoses. Although several topics were inevitably not included in this symposium, we nevertheless hope that it represents an integration of basic pathomorphological research with current clinical findings in the area of pathochemical markers in psy­ chiatry.

We organized the Seventh International Winter Conference on Neurodegeneration and Neuroinflammation in a small town of Karuizawa in Nagano Prefecture in Japan on January 20 to 22, 1999. Karuizawa is a nice summer as well as winter resort close to the place for winter Olympic game in the year of 1998. Over 40 scientists gathered together and made hot discussion. Neurodegeneration and neuroinflammation are two major and important neurologic disorders, in which satisfactory neuroprotective and neurorestorative treatment is not available yet. For this purpose, understanding of molecular mechanisms of neuronal cell death in these two disorders is imperative. Recently, pathologic processes common to these two groups of disorders have been identified such as the involvement of inflammatory changes, microglia, cytokines, and apoptosis. We intended to involve scientists working in these two major fields together to participate in hot and fruitful discussion for the understanding of neuronal death and for developing newer methods of treatment. The science is progressing so rapidly today and we are working in a very narrow specialized area. Sometimes, we are ignorant about important discoveries in other fields. This conference was a nice opportunity for scien­ tists working different areas to meet together and to exchange their experi­ ence. This volume is the proceedings of this Winter Conference.

Zu den häufigsten Alterserkrankungen zählen heute die Parkinson’sche Erkrankung sowie Demenzen. Eine Reihe neuer Erkenntnisse der Grundlagenforschung sowie die Entwicklung neuer Neuro-Psychopharmaka für die genannten Indikationen machten eine Neubearbeitung des Bandes erforderlich. In den vergangenen zwei Jahren wurden unter den Parkinson-Mitteln neue Dopamin-Agonisten, COMT-Hemmer sowie NMDA-Antagonisten zugelassen. Zur Behandlung der Alzheimer-Demenz wurden Antidementiva (Cholinesterosehemmer) entwickelt, weitere medikamentöse Therapieeinsätze befinden sich im Stadium der klinischen Prüfung und werden ebenfalls dargestellt. In gewohnter Form illustrieren zahlreiche Tabellen und Abbildungen die einzelnen Parkinsonmittel und Antidementiva (Nootropika).

Parkinson''s disease is one of the major causes of neurological disability in adult life. It has been encountered in all races, in every region of the world and shows no preference for either sex. In general, its initial manifestations begin in the fifth decade of life. With the world population showing an increase in numbers of people in the older age groups, Parkinson''s disease will undoubtedly be encountered with increased frequency in the years to come. Though its cause is unknown, significant strides in understanding its nature and controlling its symptoms have been made during the past two decades. Contained in this volume is a comprehensive review of the present knowledge of Parkinson''s disease. Though James Parkinson is credited with the uncovering the illness which now bears his name, and his monograph on the Shaking Palsy written in 1817, is truly a medical classic, descriptions of this disease can be found in medical writings going back to the time of Galen. Indeed, he himself was the first to admit that he was not describing a new disease but bringing an old one to the attention of the medical researchers of his time so that it would become a subject of interest and investigation. Specifically, his objective was the morbid anatomist whose efforts he hoped would bring to light the cause and nature of the disorder. This, then, would become a basis for· treatment or even cure.
