Descriptive Psychiatry and the Development of Diagnostic Criteria in the History of Child Psychiatry and Phenomenological Descriptive Psychiatry

Phenomenology has been developed by philosophers like Kant and Husserl since the late 18th century. Jaspers, a German psy-chiatrist, adopted it into psychopathology studies and accumulated data by closely observing and recording the patients’ symp-toms and signs. Among descriptions done even before the psychopathology or diagnostic criteria of disorders in the field of child psychiatry was established, we can find exact and valuable descriptions matching the autism spectrum disorder or attention defi-cit/hyperactivity disorder. The diagnostic criteria of modern childhood psychiatric disorders were established based on these grounds. Phenomenological/descriptive methods in various psychiatric fields lead to medical study methods for social phenome-non such as oiettolie, hikikomori, and internet game addiction. Since Romanian orphans were adopted to the western world, de-scriptive studies along with neurobiological studies on the influence of stimulus deprivation on emotional and physical develop-ment are being conducted. While phenomenology, which was adopted by Jaspers to verify psychopathology, was developed mainly by observation and description, recent studies are explaining such descriptive phenomena even at the synapse level due to advances in neurobiology. Although phenomenological/descriptive psychiatry, describing precise and detailed experiences of pa-tients, is less applied nowadays among modern study methods, we must remember that such descriptions may lead to biological studies and provide evidence to improve the accuracy of choosing and applying treatment methods.
