Applications of Chaos Theories to Psychiatry: A Review and Future Perspectives

Abstract

AbstractThe great revolution that took place in physics at the beginning of this century, which led to a total reshaping of the science and a different approach to natural phenomena, could serve as a model for future developments in other disciplines such as neuroscience. When investigated by traditional methods, the complexity of brain mechanisms remains quite elusive; the use of new strategies should, therefore, be a high priority.Although holistic interpretations of brain functions and dysfunctions still seem futuristic, the application of chaos theories may be one way of making these interpretations more understandable. In fact, chaos mathematics can be applied to brain activity, such as that recorded, by electroencephalogram (EEG), and to the interpretation of psychopathology. Similarly, clinical phenomena could be explained in terms of nonlinear dynamics. Moreover, the application of chaos theories to psychiatry might permit the study of the relationships between genetic and environmental factors in determining syndromes and symptoms. This could encourage the development of a nonlinear dynamic psychiatry which, in turn, would allow a better understanding of research findings and, perhaps, open new horizons to psychiatric intervention.
