Does identity disturbance contribute to inhibition in borderline personality? A preliminary report.

A research protocol was developed to test a theoretical model regarding impulsivity in borderline personality (BP) disorder. It was hypothesized that the impact of identity disturbance of individuals with BP features on their response-inhibition functions could be explained by the disposition of their self-concept to increase the intensity of negative emotions. Participants with different levels of BP features were assigned to a self-description condition (N=29) that had the potential to manipulate the identity coherence, or a control condition (N=27) prior to a response inhibition task with high and low arousal emotional stimuli.

The Modulating Role of Self-Referential Stimuli and Processes in the Effect of Stress and Negative Emotion on Inhibition Processes in Borderline Personality Disorder: Proposition of a Model to Integrate the Self-Concept and Inhibition Processes.

Impulsivity is an important clinical and diagnostic feature of borderline personality disorder (BPD). Even though it has been reported that BPD individuals' inhibition performance is significantly reduced in the context of negative emotion or stress, this literature shows mixed results, raising questions about the possible role played by other factors. Winter (2016) proposed that negative emotion stimuli can be more disruptive for BPD individuals' attention control performance because they induce higher distractibility self-referential processes.

Atrophy in Alzheimer's Disease and Semantic Dementia: An ALE Meta-Analysis of Voxel-Based Morphometry Studies.

Background/objectives: Alzheimer's disease (AD) and semantic dementia (SD) have distinct episodic memory profiles despite the hippocampal atrophy that characterizes both diseases. The aim of this study was to delineate the pattern of gray matter (GM) atrophy associated with AD and SD as well as any differences in these patterns by pooling together the results of previous voxel-based morphometry (VBM) studies.Methods/Overview: We conducted a meta-analysis of VBM studies that investigated GM atrophy in AD patients versus controls (CTRLs) and in SD patients versus CTRLs using the activation likelihood estimation (ALE) approach.
