Does application of complexity theory simplify concepts of psychiatry: Analogies and insights

Scientific curiosity has not been able to explain the cause of psychiatric illness based on primarily biological or social paradigm. Available literatures were explored to understand causality of psychiatric illness from perspective of physics. Theory of complexity and other relevant theories were extrapolated to address these questions. Mental illness appeared to be a complex interplay of reductionism and emergentism, genetic and epigenetics, stress and the vulnerability or the core and the periphery. Mental illness displayed complex interaction between biological trait and environmental state.

Biopolíticas da depressão nos imigrantes Africanos

Este artigo foca o tema controverso das biopolíticas da depressão em imigrantes, em particular nos originários da África sub-sahariana. Os sintomas depressivos, ligados à ansiedade, são identificados também pela nova e mais importante patologia mental dos imigrantes: a Síndroma de Ulisses, de stress múltiplo e crónico, já definido como "o mal do século vinte e um", e que atinge principalmente os africanos. Não só entre estes imigrantes mas também em África, segundo um estudo conduzido pela OMS, a depressão tornou-se uma das principais patologias mentais. O tratamento farmacológico do sofrimento, entendido como fenómeno orgânico, é considerado o único caminho possível, silenciando os processos históricos, políticos e socioeconómicos que lhe estão na base. A atenção é portanto focada na saúde mental do indivíduo, desviando-a de problemas sociais de difícil resolução, que necessitariam de respostas económicas e políticas.

Concepts of disease: their relevance for psychiatric diagnosis and classification

To deal effectively with the understanding, description and classification of mental morbid conditions, we must address the intricate concept of disease, illness or disorder in mental health. To do so, one needs to consider biological, psychological and social frameworks. These levels of analysis can offer avenues for greater understanding of the bases of illness as well as better ways of formulating its description and classification. Conceptual, epistemological and empirical data analyses are relevant and necessary. All these efforts should be aimed at serving and advancing the main purposes of classification and diagnosis, the chief encompassing one being enhancement of clinical care and public health. Although no definition of mental disorder may strictly embrace every condition of concern, some flexible definitional guidelines within a biopsychosocial framework may be helpful for advancing psychiatric nosology.
