Abstract
Borderline personality disorder (BPD) is a severe psychiatric disease that predominantly manifests in young adults through a pattern of instability in interpersonal relationships, self-image, and affect, along with intense impulsivity.
This disorder is a serious psychiatric illness that affects 5.9% of the population. It is considered to be the most prevalent personality disorder in the clinical setting, accounting for 10% of psychiatric outpatients and 15–20% of hospitalized patients. Despite its high prevalence, however BPD is often underdiagnosed.
The clinical course of BPD patients is variable, and almost constantly unstable with acute periods of crisis, auto-mutilation, aggressive behavior, suicide attempts, drug abuse, etc. All of them comes along with an important affective correlate.
Social cognition is a broad term that includes a wide variety of interrelated cognitive processes that enable successful and adaptive behavior in a social context. It includes, among other things, the ability to recognize social cues such as facial emotions, the ability to understand others’ mental states [known as theory of mind (TOM) or mentalizing], the ability to share the experiences and emotions of others, as well as the capacity to regulate one’s emotional responses to others. Disturbances in these social cognitive abilities are important predictors of social and functional impairments in psychiatric disorders.
Social cognition is a specialized cognitive domain that promotes effective social communication and relationships. Two aspects of mentalizing are functionally and neurally recognizable: the attribution of emotional states and the inference of thoughts, intentions, and desires. Mental state decoding refers to the ability to detect cues, for example facial expressions to infer what another person is thinking or feeling. Mental state reasoning denotes reflection about possible reasons that underlie others’ behaviours based on evidence from multiple sources including context and personal history of the object of the mental state attributions.
