The Future of Biological Psychiatry

Progress in biological psychiatry is contingent upon progress in neurobiology and progress in research of proper characterization and assessment of abnormal behavior. Advances in neurobiology are rapid and steady; however, advances are few and far between in psychopathology. In many ways, developments over the past two decades run counter to what I believe to be diagnostic pre-requisites for fruitful biological research in psychiatry. I presume this to be a major reason why thus far biology has made no significant contributions to the diagnoses of mental disorders.For progress to occur in biological psychiatry, the traditional diagnostic philosophies and attitudes must be reevaluated and alternative diagnostic approaches put into practice. This and the diagnostic method of functional psychopathology are reviewed in this article, with a focus on how the functional psychopathological approach could contribute to the advancement of the diagnostic process in psychiatry, and the opportunities it provides for biological psychiatric research.

Monoamines and CSF: relevance to neuropsychiatric disorders

SummaryOver the past 25 years much effort has been put into the research of the relationship between neuropsychiatric disorders and the concentrations of CSF-monoamine metabolites. Most of this research has beenfocused on the relation between CSF-concentrations of 5-hydroxyindoleacetic acid (5-HIAA) and homovanillic acid (HVA) and specific symptomatological entities, particularly schizophrenia, Alzheimer's dementia and endogenous depression. It appeared that specific relations between diseases and CSF-concentrations of monoamine metabolites cannot be longer maintained and that a more functional psychopathology should be considered as the future research strategy.
