This book is based on lectures held at the In- ternational Expert
Meeting "Current Update on Psychoimmunology" (September 26-28, 1996,
Graz, Austria), which was organized by "Ver- ein zur Forderung der
Wissenschaft und For- schung an der Universitatsklinik fUr Psychia- trie
Graz" (Chairman: H. -G. Zapotoczky; Coor- dinators: M. Lux, G.
Wieselmann; Local Orga- nizing Committee: E. Braun, M. Bretterklieber,
H. Hausler, G. Herzog, S. Kriechbaum, S. Sper- lich). The book tries to
close the gap between immunological findings on one hand, psychological,
psychopathological, electrophysiological and neuroimaging aspects on the
other. It also deals with the issue of "cause and effect" (of
immunological alternatives) in different or- ganic and/or mental
disorders, and emphasizes the necessity of consid- ering a variety of
treatment strategies. There are dynamic interactions and several
important similarities between the immune system and the central nervous
system, which help to lay the rational basis for "psy- choimmunology".
Both systems have the capacity for memory and both play vital roles in
adaptation and defence. Furthermore, in each system pathological changes
can occur in the event of inappropriate responses to internal or
external stimuli, leading to psychiatric as well as organic illnesses
and autoimmune diseases could also arise as a consequence of dysfunction
and maladaptation, respectively. Finally, the editor is grateful to all
the authors and experts for their contributions to the meeting and for
preparing their manuscripts for this publication. Graz, November 1997 G.
