Misophonia matters: A case study of the role of brain imaging in debates over new diagnoses.

Misophonia has gained attention in scientific circles that utilise brain imaging to validate diagnoses. The condition is promoted as not merely a symptom of other psychiatric diagnoses but as a discrete clinical entity. We illustrate the social construction of the diagnostic category of misophonia through examining prominent claims in research studies that use brain imaging to substantiate the diagnosis. We show that brain images are insufficient to establish the 'brain basis for misophonia' due to both technical and logical limitations of imaging data. Often misunderstood as providing direct access to the matter of the body, brain images are mediated and manipulated numerical data (Joyce, 2005, Social Studies of Science 35(3), p. 437). Interpretations of brain scans are further shaped by social expectations and attributes considered salient to the data. Causal inferences drawn from these studies are problematic because 'misophonics' are clinically pre-diagnosed before participating. We argue that imaging cannot replace the social process of diagnosis in the case of misophonia, nor validate diagnostic measures or otherwise substantiate the condition. More broadly, we highlight both the cultural authority and inherent limitations of brain imaging in the social construction of contested diagnoses while also illustrating its role in the disaggregation of symptoms into new diagnoses.

Greening, Revitalization, and Health in South Wilmington, Delaware.

We highlight the potential for paradoxical impacts of green infrastructure integrated with urban redevelopment. Absent directly addressing social inequalities in parallel efforts, green infrastructure may lead to negative health outcomes of disadvantaged residents, including eventual displacement. We present the research literature and reviews on this topic. We next highlight the case of recent in-migration of higher-income Whites and others in South Wilmington, Delaware, spurred on by high-end Riverfront redevelopment at Christina Landing. This migration may obscure how greening efforts-such as a new wetlands park to control area flooding-influence health outcomes in Southbridge, a low-income, African American neighborhood also within South Wilmington. The area's Census tract boundary, often used in both health and equity assessments, is shared by these distinctive communities. When viewed through the lens of inequality, greening can have multi-faceted impacts that structure health outcomes. We underscore the importance of the mitigation of its potentially harmful effects.

The relationship between seriously considering, planning, and attempting suicide in the youth risk behavior survey.

The assumed ordinal relationship between seriously considering, planning, and attempting suicide in the 1999 Youth Risk Behavior Survey was examined by constructing a trajectory that identified all possible response patterns among the four questions measuring suicidal activity. Statistical analysis tested for differences in frequency of risk behaviors across levels of the trajectory. Overall, the trajectory provided insight to the progression of adolescent suicidal activity and demonstrated usefulness as a measure of suicidal intent. Significant differences between means of dependent variables at each level of the normative trajectory supported the hypothesis that frequency of risk behaviors increases monotonically with successive suicidal thought and behavior.
