Characterizing impulsivity profile in patients with obsessive–compulsive disorder

Abstract

Present findings showed higher impulsivity levels in OCD patients versus controls, particularly in the attentional area, and ultimately suggest a potential cognitive implication.

Response to Cognitive impulsivity and the behavioral addiction model of obsessive–compulsive disorder: Abramovitch and McKay (2016)

“…This finding is consistent with other studies that showed predominantly increased cognitive impulsivity in OCD patients (Benatti, Dell’osso, Arici, Hollander, & Altamura, 2014; Ettelt et al., 2007; Sohn, Kang, Namkoong, & Kim, 2014). Moreover, our two other results, risky decision-making on the IGT and fewer draws to decision on the Beads Task might also reflect impulsivity predominantly on a cognitive reflective level (Voon et al., 2015).…”

Cyclothymia reloaded: A reappraisal of the most misconceived affective disorder

“…Both are marked out, in an egosyntonic way, by harmful or dangerous, but rewarding, behavior, impulsiveness, poor insight and emotional instability. Impulse control disorders and cyclothymia show a large overlap area, on the comorbidity spectrum, with other mental disorders, including anxiety disorders (Benatti et al, 2014;Del Carlo et al, 2013;, alcohol and substance abuse (Maremmani et al, 2006;Pani et al, 2010;Unseld et al, 2012) and eating disorders (Alciati et al, 2007;Ellickson-Larew et al, 2013;Lunde et al, 2009;Perugi et al, 2006). In cyclothymic subjects, mood instability and impulsiveness are interrelated and are key features of hypomanic or mixed periods characterized by behavioral disinhibition, poor insight and marked instability between tension, dysphoria and satisfaction.…”

Shared and disorder-specific task-positive and default mode network dysfunctions during sustained attention in paediatric Attention-Deficit/Hyperactivity Disorder and obsessive/compulsive disorder

“…Both disorders have also been linked to increased spontaneous mind-wandering (Mowlem et al, 2016, Seli et al, 2016, Seli et al, 2015), which is proposed to reflect an imbalance between task-positive and default mode networks (Christakou et al, 2013, Metin et al, 2015), and to underlie poor performance on sustained attention tasks, as attention is focused on internal thoughts, thereby limiting attention resources available for task-relevant processing (Thomson et al, 2015). Moreover, both ADHD and OCD patients self-report impaired executive attention abilities (Armstrong et al, 2011, Benatti et al, 2014, Grassi et al, 2015, Malloy-Diniz et al, 2007, Nandagopal et al, 2011, Sohn et al, 2014). …”
