The Neurosocial City by Des Fitzgerald & Nikolas Rose What are sociologists and urbanists to make of the characteristic patterns of mental disorder that have been observed in cities since the nineteenth century? What are planners and policy-makers to make of them? Do such patterns emerge because those with degenerate constitutions migrate to certain parts of the city where they feel comfortable or where they might indulge their vices? Do they come from the stresses and strains of the urban itself – the hubbub, the noise, the enforced proximity to strangers, the unnatural and frenzied atmosphere? Are they embedded in family structures that cluster in urban areas – whether small, single parent families, large, conjoined families, or loose strings of isolated men and women, seemingly cut free of the traditional bonds of affiliation? Is it that those who live in certain parts of the city are simply poor, deprived, excluded, and made repeatedly subject to the ongoing violence of race and class? Or should we focus more on environmental factors such as housing density, exposure to fumes from vehicles – even the weather? And how, in the middle of all of this, should we think about the differences between psychiatric diagnoses?
