Impulsivity profile analysis and it’s potential role in the differential diagnostics of adult Attention Deficit Hyperactivity Disorder and Borderline Personality Disorder

Abstract

IntroductionImpulsivity is a complex construct, having at least three factors: 1) impulsivity as a personality trait, 2) ismpulsive action – waiting and stopping impulsivity and 3) choice impulsivity. Impulsive symptoms are present in Attention Deficit Hyperactivity Disorder (ADHD) and Borderline Personality Disorder (BPD) as well, eventhough impulsvity profile significantly differs.ObjectivesOur aim is to describe the impulsivity profile in adult ADHD (aADHD) and BPD in comparison with the control group, and describe a characteristic pattern, which associates with these disorders.MethodsaADHD (n=100) and BPD Patients (n=63) were included, based on DSM-5 diagnostic criteria. Healthy control subjects (n=100) were screened using the Derogatis Symptom Checklist (SCL-90). Comorbid psychiatric disorders were assessed by structured clinical interviews and those who have both aADHD and BPD were excluded from the study. Participants were further investigated with online questionnaires: e.g. Barratt Impulsiveness Scale (BIS-11) Difficulties in Emotion Regulation Scale (DERS) and neuropsychological tests, like CANTAB Rapid Visual Processing, Stop Signal Task, and the Rogers’ decision-makingtest.ResultsBased ont the BIS-11 results, significantly higher attentional impulsivity was present in adult ADHD compared to BPD (p
