Psychose et impulsivité : un mauvais mariage

Abstract: L'impulsivité chez le patient atteint de troubles psychotiques se manifeste par une multitude de comportements pouvant avoir un impact majeur sur l'évolution et le traitement de la maladie ainsi que sur le fonctionnement occupationnel et social. Différentes hypothèses expliquant les comportements impulsifs et leurs conséquences pour le patient et son entourage seront explorées. Des approches thérapeutiques sont identifiées afin d'améliorer la prise en charge des patients avec des troubles psychotiques présenta… Show more

“…Although these studies demonstrated an elevated level of impulsivity with occurrence of violence in a subgroup of patients, they didn’t clearly establish a link between VB and impulsivity. These conflicting results may also reflect a conceptual problem: if there is a general consensus regarding the definition on impulsivity which could be described as “a predisposition towards rapid, unplanned reactions to internal or external stimuli without regard to the negative consequences of these reactions to the impulsive individual or to others ” [21], impulsivity is also considered as a multidimensional concept [16, 22–24] and is assessed differently depending on the author. Finally, the fact that impulsivity can be investigated either as a personality trait or as a personality state which can vary according to pathology [13, 14] or situational factors, also contributes to the inconsistencies between studies.…”

“…In the EEP, prospective cohort studies have also shown that impulsivity is associated with serious aggression ( 37 , 50 ), either directly or indirectly. Several authors suggest that the relationship between impulsivity and VB may be mostly indirect ( 89 ) and mediated by other factors, like early conduct disorder, antisocial personality disorder ( 81 ), psychopathic trait, affective instability and negative emotions ( 73 ), as well as positive symptoms ( 78 , 79 ). In addition, substance use is frequently highlighted as a dimension that may also underlie this link ( 78 , 81 , 90 ).…”

“…In psychosis, it is not yet known whether it is the pre-existing impulsive trait that drives the use or whether it is the use that increases impulsivity ( 76 , 78 , 95 ). Various authors show that patients who use cannabis are more impulsive ( 76 , 79 , 96 ) than those who do not. Repeated CU may also increase impulsivity ( 97 100 ) and impulsivity is thought to play a key role in the development and maintenance of drug dependence, including cannabis ( 70 , 78 , 98 , 101 103 ).…”

“…Impulsivity is thought to be related to dysfunction in a brain circuit comprising cortico-subcortical regions, including the frontal cortex, pallidum, striatum and thalamus (Abdel-Baki, Turgeon, Chalfoun, & Nguyen, 2013;Aron, Behrens, Smith, Frank, & Poldrack, 2007;Hoptman, 2015), which results in a failure to inhibit inappropriate behaviour (Hoptman, Antonius, Mauro, Parker, & Javitt, 2014).…”

Although the understanding of how impulsivity may emerge during adolescence in relation to specific brain circuits and their maturation is of considerable interest (Whelan et al, ), it as received little attention in the field of early psychosis (EP) (Nielssen, Malhi, McGorry, & Large, ).…”
