La Belle Indifference
La belle indifference is defined in DSM-5 as a “lack of concern about the nature or implications of the symptom” and is listed as an associated feature supporting the diagnosis of conversion disorder (APA 2013, p. 320). Extant neurobiological models converge on the conceptualization of conversion symptoms as involuntary responses to threat reflecting errors in body state information processing and representation (Kozlowska 2005). Theories suggesting frontal lobe hypoactivation as an explanation for apathy and indifference have also been proposed (Spence et al. 2000) as well as theories suggesting a link to right hemispheric dysfunction (Stone et al. 2006).
