The relationship between personality disorders and substance abuse disorders

Abstract

IntroductionA frequently observed fact in clinical practice is the relationship between Substance Abuse Disorders and Personality Disorders (PD). Epidemiological investigations have found that diagnoses of PD seem to increase vulnerability to other pathologies, including substance abuse and addiction, and it is possible to speak of comorbidity or dual pathology.ObjectiveTo describe the comorbidity between PD and substance abuse disorders.MethodsSystematic review of the literature on the subject. The databases consulted were Dialnet, Pubmed and Cochrane.ResultsThe various studies allow estimating that between 65% and 90% of subjects treated for substance abuse or dependence have at least one concomitant PT. Studies show a higher prevalence of Cluster C for alcohol consumption and Histrionic, Narcissistic, Boundary and Antisocial Disorders (Cluster B) for illegal drugs, mainly cocaine. Cluster B is the one that the literature has most related to substance use. It is also the group in which there is a greater predominance of impulsivity, which would be worth remembering its role as a vulnerability factor for addictions.ConclusionsWhat the research has shown is that a good deal of the problems that accompany substance use come from dysfunctional patterns of behavior that are maintained over time with high stability and can justify, in part, both the persistence of The addictive behavior as the difficulty of handling the patients who present them. At present, although the high comorbidity between TP and substance use is sufficiently documented, many questions still remain to be solved.Disclosure of interestThe authors have not supplied their declaration of competing interest.

A Latent Class Analysis of Forensic Psychiatric Patients in Relation to Risk and Protective Factors

“…Likewise, at the item level, this class displayed the highest levels of antisocial behavior, impulsivity and addiction. Many previous studies have consistently related substance use, antisocial behavior, and greater levels of impulsivity to cluster B PDs, which is the main characteristic of the antisocial class identified in this study (e.g., Perry and Körner, 2011;Goretti et al, 2017;Schmitter et al, 2021). It could be that poor impulse control and addiction problems put patients in the antisocial class at risk for more serious violent offenses than patients in the other classes.…”

The Long-Term Changes in Dynamic Risk and Protective Factors Over Time in a Nationwide Sample of Dutch Forensic Psychiatric Patients

“…In addition, we did not find significant differences between cluster B and non-cluster B PDs patients in the trajectories of the clinical scale, and the protective skills subscale. It could be speculated that differences were only found for the risk factors as they are more pronounced in patients with cluster B PDs ( 17 , 23 , 42 – 44 ) than the lack of protective factors ( 17 , 68 ).…”

“…The latter represents one of the main factors associated with serious and persistent criminal offending ( 40 ), while poor self-regulation and higher impulsivity are considered crucial in explaining criminal behavior according to the general theory of crime ( 41 ). In addition, many previous studies have often linked cluster B PDs to SUD, and antisocial behavior [e.g., ( 42 – 44 )], i.e., factors that are also significant predictors of violent reoffending ( 1 ).…”

Synthetic Cannabinoids Impact on Cognitive Functions

“…BPD was extremely common about 76% and 12% APD. All of this data conclude that addiction is a risk factor for Cluster B personality disorders (Goretti et al, 2017).…”
