RESUMEN
OBJECTIVE: A large body of literature has examined the links between the use of dopamine replacement therapy (DRT) in Parkinson's disease (PD) and the development of "impulsive-compulsive behaviors (ICBs)." Little is known regarding the link between the development of ICBs and health-related quality of life (HRQOL). We aimed to explore the factors that are associated with poorer HRQOL, especially in relation to DRT-induced ICBs, in a sample of PD patients. METHODS: This PARKADD (PARK: PARKinson's disease; ADD: behavioral ADDictions) study was a prospective caseâcontrol study initially designed to assess the factors associated with ICBs in PD patients. A prospective clinical follow-up was added, aiming to capture the long-term evolution of HRQOL in relation to ICBs occurring or worsening after the beginning of PD. We focused on sociodemographic and PD characteristics and the history or presence of ICBs. HRQOL was measured using the Parkinson's Disease Questionnaire-8. A multivariate linear regression was performed to identify factors related to poorer HRQOL. RESULTS: A total of 169 patients were eligible for the follow-up study. The presence of an ICB, a higher levodopa equivalent daily dose (LEDD) and a longer PD duration were significantly associated with poorer HRQOL, with an interaction between LEDD and PD duration. CONCLUSION: The presence of an ICB was related to poorer HRQOL and should be considered a crucial factor for the management of PD patients. Several studies were recently published that provide guidelines for the management of these patients, with recommendations based on two key principles: prevention and specific treatment.
RESUMEN
INTRODUCTION: Since the first description of sex addiction (SA) by Carnes, research on this problematic behaviour has continued to grow, and the association with attention-deficit hyperactivity disorder (ADHD) appears to be frequent. This study aimed to estimate the frequency of a history of probable ADHD in a population of patients with SA and to explore the factors associated with it. METHODS: One hundred 85 patients referred to the Nantes University Hospital for SA between 2011 and 2020 were included. Patients completed the Sexual Addiction Screening Test (SAST) or its revised version (SAST-R) to establish the presence of SA. As the SAST-R was not validated in French, we conducted a validation study for the French version. ADHD was screened using the Wender-Utah Rating Scale in childhood and the Adult ADHD Self-Report Scale in adulthood. A multivariate logistic regression model was used to identify factors associated with the presence of a history of probable ADHD. RESULTS: Childhood ADHD was identified in 36% of patients with SA. Factors associated with the presence of a history of probable ADHD were a low education level, an earlier age of onset of problematic sexual behaviour, another addictive disorder, an anxiety disorder, impulsivity (high negative urgency score), and high scores on harm avoidance and novelty-seeking temperament scales. Furthermore, the French version of the SAST-R displayed good psychometric properties, especially excellent sensitivity. CONCLUSION: The frequency of a history of probable ADHD among patients with SA is consistent with the literature and close to the highest range. Specific personality traits in patients with both SA and a history of probable ADHD could induce lasting problems of adaptation, which may precipitate the development of SA or maintain it.

Background and aims: This research aimed to characterize social information processing abilities in a population of regular nondisordered poker players compared to controls. Methods: Participants completed the Posner cueing paradigm task including social cues (faces) to assess attention allocation towards social stimuli, including the effect of the presentation time (subliminal vs supraliminal) and of the emotion displayed. The study included two groups of participants: 30 regular nondisordered poker players (those who played at least three times a week in Texas Hold'em poker games for at least three months) and 30 control participants (those who did not gamble or gambled less than once a month, whatever the game). Results: The group of regular nondisordered poker players displayed an enhancement of the inhibition of return during the Posner cueing task. This means that in valid trials, they took longer to respond to the already processed localization in supraliminal conditions compared to controls. However, our results did not evidence any particular engagement or disengagement attention abilities toward specific types of emotion. Discussion and Conclusions: These results suggest that regular nondisordered poker players displayed social information processing abilities, which may be due to the importance to efficiently process social information that can serve as tells in live poker. The observed enhancement of the inhibition of return may permit poker players to not process a localization that has already processed to save attentional resources. Further research regarding the establishment of the IOR in other forms of gambling and with non-social cues needs to be performed.

BACKGROUND: In recent years, many studies have explored the associations among impulsivity, history of abuse, the emergence of eating disorders with episodes of binge eating (EDBE) and their severity. Nevertheless, factors associated with successful clinical outcomes of EDBE are still unknown. Our study aimed to test the hypothesis that a history of abuse is associated with unsuccessful clinical outcomes of EDBE through an effect mediated by impulsivity. METHODS: We assessed patients older than 15 years, 3 months with EDBE at inclusion and at 1 year. Recovery was defined as the absence of eating disorders at 1 year. A mediation analysis was performed by means of structural equation modelling. RESULTS: We included 186 patients in our analyses (54% bulimia nervosa, 29% anorexia nervosa binge eating/purging type and 17% binge-eating disorder); 179 (96%) were female. One-third (n = 63) of patients reported a history of abuse, and recovery was observed for 20% of the sample (n = 38). Contrary to our assumption, a history of abuse was not associated with the absence of recovery of EDBE at 1 year. Factors unfavourable for achieving recovery were anxiety disorders (odds ratio [OR] 0.41), vomiting (OR 0.39), physical hyperactivity (OR 0.29), negative urgency and a lack of perseverance (OR 0.85 for both). Only positive urgency was positively associated with recovery (OR 1.25). LIMITATIONS: We excluded 219 patients lost to the 1-year follow-up. CONCLUSION: Our findings may help to deconstruct the empirical belief that traumatic events may interfere with the successful course of treatment for eating disorders. A high level of positive urgency may be associated with more receptivity to care.

Background and aims: Parkinson's disease (PD) is one of the most prevalent neurodegenerative diseases. First-line medications consist of drugs that act by counteracting dopamine deficiency in the basal ganglia. Unfortunately, iatrogenic impulsive-compulsive behaviors (ICBs) can occur in up to 20% of PD patients over the course of their illness. ICBs must be considered multifactorial disorders that reflect the interactions of the medication with an individual's vulnerability and the underlying neurobiology of PD. We aimed to explore the predictive genetic, psychopathological and neurological factors involved in the development of ICBs in PD patients by building a complete model of individual vulnerability. Methods: The PARKADD study was a case/non-case study. A total of 225 patients were enrolled ("ICB" group, N = 75; "no ICB" group, N = 150), and 163 agreed to provide saliva samples for genetic analysis. Sociodemographic, neurological and psychiatric characteristics were assessed, and genotyping for the characterization of polymorphisms related to dopaminergic and opioid systems was performed. Results: Factors associated with "ICBs" were younger age of PD onset, personal history of ICB prior to PD onset and higher scores on the urgency and sensation seeking facets of impulsivity. No gene variant was significantly associated, but the association with the opioid receptor mu 1 (OPRM1) rs1799971 polymorphism was close to significance. Discussion and conclusions: The influence of gene-environment interactions probably exists, and additional studies are needed to decipher the possible role of the opioid system in the development of ICBs in PD patients.

Introduction: Dual diagnosis (DD) is defined as the co-occurrence of at least a psychiatric disorder and at least an addictive disorder. Most studies about DD considered substance use disorders. In 2018, gaming disorder (GD) was recognized as a formal disorder and integrated into the category of addictive disorders in the 11th version of the International Classification of Diseases. Our objectives were to measure DD prevalence among GD patients and to assess factors associated with the presence of DD. Methods: As part of the EVALuation of behavioral ADDictions (EVALADD) cohort, 92 patients with GD were included in the present study. Psychiatric disorders, including anxiety, mood, and psychotic disorders, were explored with the Mini International Neuropsychiatric Interview (MINI 5.0.0). Probable adult attention-deficit/hyperactivity disorder (ADHD) was screened with the Wender Utah Rating Scale (WURS) in childhood and with the ADHD Self-Report Scale-V1.1 (ASRS) in adulthood. Finally, personality was assessed using the 125-item version of the Temperament and Character Inventory (TCI-125), motives for gaming with the Videogame Motives Questionnaire (VMQ) and attachment styles with the Relationship Scales Questionnaire (RSQ). To measure the prevalence of DD among GD patients, we considered the occurrence of current GD with current anxiety, mood, or psychotic disorders, or with probable current ADHD. We also performed a multivariate analysis to identify independent factors associated with DD. Results: More than half (55.4%) of GD patients suffered from DD. We found a high prevalence of probable ADHD (38%) and anxiety disorders (29% suffering from generalized anxiety disorder, social, agoraphobia or panic disorder). Four variables were significantly associated with DD: suicidal thoughts [odds ratio (OR) = 6.83, 95% confidence interval (95%CI) (1.66-28.09)], VMQ "coping" scores [OR = 1.18, 95%CI (1.01-1.38)], TCI-125 "harm avoidance" scores [OR = 1.04, 95%CI (1.01-1.07)] and "novelty seeking" scores [OR = 1.03, 95%CI (1.00-1.06)]. Discussion: The prevalence of certain psychiatric disorders among GD patients far exceeded that observed in the general population. Both ADHD and suicidal ideations should particularly be screened among GD patients. Specific interventions targeting personality dimensions associated with DD but also on the management of negative affect should represent new treatment opportunities.
RESUMEN
BACKGROUND: The resurgence of heroin use and the misuse of pharmaceutical opioids are some of the reasons for a worldwide increase in opioid dependence. Opioid Medication Therapies (OMT) have amply demonstrated their efficacy. From a medical point of view, the main objectives of OMT concern medical and social outcomes, centred on risk reduction and the cessation of opioid use. But patient points of view can differ and few studies have explored opioid-dependent patient viewpoints on their OMT. This variable seems important to consider in a patient-centred approach. The aim of our study was to explore points of view of people who use drugs (PWUD) treated with OMT, in a large multicentre sample. METHOD: A cross-sectional multicentre study explored the points of view of PWUD with Opioid Use Disorder following OMT. Data regarding the patients' points of view were collected using a self-administered questionnaire developed by the scientific committee of the study. A descriptive analysis and an exploratory factor analysis were performed to explore the structure of items exploring patient viewpoints. RESULTS: 263 opioid dependent PWUD were included, a majority were men consuming heroin prior to being prescribed OMT. 68% were on methadone, 32% were on buprenorphine. Most PWUD identified a positive impact on their lives, with 92.8% agreeing or strongly agreeing that OMT had changed a lot of things in their lives. The exploratory factor analysis identified three factors: (F1) items related to points of views concerning the objectives and efficacy of OMT; (F2) items related to the legitimacy of OMT as a treatment compared to a drug, (F3) items related to experiences and relationships with OMT. CONCLUSION: Patient viewpoints on efficacy were correlated with the pharmacological benefits of OMT and with the associated psychosocial measures. The implications of OMT in relationships, such as the feeling of being judged, concerned a majority. Points of view were ambivalent concerning the role of OMT as a treatment or as a drug. Involving patient points of view in therapeutic strategies decisions could help enhance positive views among PWUD on OMT and help PWUD towards their recovery. TRIAL REGISTRATION: OPAL study was registered: (NCT01847729).

BACKGROUND AND AIMS: Since June 2018, gaming disorder (GD) has been recognized as a disease. It is frequently associated with attention deficit hyperactivity disorder (ADHD), as there are common vulnerability factors and bidirectional interactions between the two disorders. This study aims to evaluate the presence of ADHD symptoms and predictive factors of ADHD among patients with GD. METHODS: Ninety-seven patients ≥16 years old referred to the University Hospital of Nantes between 2012 and 2020 for GD were included. The diagnosis of GD was given a posteriori in accordance with the new ICD-11 GD definition. ADHD was screened using the Adult-ADHD Self-Report Scale and the Wender-Utah Rating Scale. A multivariate logistic regression model was used to identify explanatory factors for ADHD-GD comorbidity. RESULTS: The rate of GD patients who screened positive for ADHD was 39%. Predictive factors of ADHD-GD comorbidity were impulsivity (higher score on the negative urgency dimension) and low self-esteem. DISCUSSION: The rate of ADHD found among patients with GD is consistent with that from the literature on internet GD but higher than that found for other behavioural addictions. The identification of a higher negative urgency score and low self-esteem as predictive factors of AHDH-GD comorbidity indicates that gaming could be considered a dysfunctional way to cope with emotional dysregulation in ADHD or to virtually escape. CONCLUSIONS: Comorbid ADHD must be taken into consideration to minimize its functional impact on GD patients and gaming-related damage. In contrast, the evaluation of gaming habits in patients with ADHD could be useful for both prevention and care.
RESUMEN
Background: Many features of Internet gambling may impact problem severity, particularly for vulnerable populations (availability, anonymity, a convenience and ease of play, digital forms of payment, and a higher level of immersion). To prevent the risks associated with excessive gambling and to inform gamblers, we need responsible gambling strategies. Gambling-related warning messages are one possible strategy that can help minimizing gambling-related harm. Methods: Our experimental study aimed to evaluate the effectiveness of self-appraisal and informative pop-up messages compared to a control condition (blank pop-up messages), for both at-risk (ARG) and low risk/non-problem Internet gamblers (LR/NPG) according to their favorite type of game, in a semi naturalistic setting and with a 15-day follow-up. During the experimental session, participants were invited to gamble on their favorite website with their own money in the laboratory. Effectiveness was investigated through the impact of pop-ups on gambling behavior (money wagered and time spent), craving, cognitive distortions, and gambling experience, taking into account message recall. We analyzed data from 58 participants, playing preferentially either to skill and chance bank games (sports betting, horse race betting) and skill and chance social games (poker). Results: We observed a significant decrease in the illusion of control for ARG in the informative pop-up condition at the 15-day follow-up. A significant effect of self-appraisal pop-ups compared to blank pop-up messages was also demonstrated only for sport and horse bettors, with a decrease on time spent gambling and an increase of gambling-related expectancies at the follow-up. Finally, we also observed that a majority of the participants were disturbed and irritated by pop-ups during their gambling session. Conclusions: The results of our study demonstrated the limited impact of pop-up warning messages on gambling behavior and cognition in Internet gamblers according to the type of game and the status of gamblers. The limited impact of warning messages on gambling behavior and the inconvenience of the pop-ups for Internet gamblers lead us to only consider warning messages as one piece of a larger responsible gambling strategy. Trial Registration Number: NCT01789580 on February 12, 2013.
RESUMEN
(1) Background: Opioid use disorder (OUD) is a complex condition that can require long-term treatment. Pharmacological therapy for OUD involves treatment with opioid agonists (OMT) tailored to individual profiles. The aim of our study in daily clinical practice was to compare the profiles of patients treated with methadone (MTD) and those using buprenorphine (BHD or BHD-naloxone-NX). (2) Methods: A cross-sectional multicentre study explored the psychological, somatic and social profiles of patients with Opioid Use Disorder (OUD) following Opioid Maintenance Treatment (BHD, BHD/NX, or MTD). Descriptive and comparative analyses were performed. (3) Results: 257 patients were included, a majority were men using heroin. A total of 68% (178) were on MTD, 32% (79) were on BHD. Patients with MTD were significantly more likely to report somatic damage, and more likely to be younger and not to report oral or sublingual use as the main route for heroin or non-medical opioids. (4) Conclusions: In daily clinical practice, somatic damage was significantly more severe among MTD patients. Age and route of administration also differed, and our results could raise the issue of the type of OMT prescribed in case of non-medical use of prescribed opioids. These hypothesis should be confirmed in larger studies.

Wagering inducements are part of loyalty/reward programs implemented by online gambling operators to retain or attract consumers. They constitute incentives to bet that are offered to gamblers provided that they perform certain betting-related activities. They are often considered risk factors for gambling problems, but studies exploring the actual impacts of such incentives are scarce. The objective of the present study was to assess the actual impact of wagering inducements on gambling behaviors, cognitions, and emotions of online gamblers. One hundred seventy-one adults (18-65 years old) who gamble on a regular basis on the Internet, including at-risk and recreational gamblers, were recruited through media announcements and in panels from survey institutes. Participants were randomly assigned to one of four experimental conditions, in which a defined amount of money was given to the gambler with a bank e-card system during an experimental gambling session to simulate a wagering inducement (10, 50, 100, or 200), or the control condition, in which no incentive was given. The experimental gambling session was designed to be as natural as possible (participants gambled with their own gambling account and their own money). Participants completed a pretest interview, took part in the experimental gambling session, and then completed a post-test interview. The impact of wagering inducements was estimated on objective (money wagered and time spent gambling during the gambling session) and subjective (cognitive distortions, enjoyment of gambling, loss of control, and respect of usual gambling habits) gambling endpoints that were compared between conditions. Two-thirds of participants reported having already received wagering inducements at some point of their gambling course. Although no effect was demonstrated on time spent gambling, inducements increased money wagered, gambling-related expectancies and perceived loss of control. In particular, it seems that wagering inducements could lead to extreme expenses, especially for at-risk gamblers. This research suggests that regulating wagering inducements could be helpful for prevention and early intervention. Future research on the impacts of wagering inducements is still needed, especially more ecological studies based on behavioral tracking data and studies assessing the differential impacts of various incentive types. Clinical Trial Registration: NCT01789580 (ClinicalTrials.gov).
RESUMEN
Background: Opioid use disorder (OUD) is a worldwide major health concern due to increased early mortality and morbidity. Opioid substitution therapy (OST) is approved in the context of a global OUD treatment (OUDT), in conjunction with psychosocial interventions. Many factors can explain why unsuccessful treatment rates remain high. While the phenomenon of addiction switching is often proposed, it is not known whether this also includes gambling addiction. The primary objective of the OPAL study was to determine the prevalence of coaddictions, including problem gambling, among patients with OUDT. Secondary objectives were to assess the rate of unsuccessful OUDT and to characterize the associated factors. Methods: For this observational transversal multicenter study, patients with OUDT including OST for at least 6 months were recruited. Clinical assessment was based on a clinically structured interview and a set of self-reported questionnaires. Coaddictions were screened using the Fagerström, the CRAFFT, and the Lie/Bet questionnaires. Unsuccessful OUDT was defined as the persistence of opioid use and/or the worsening of another substance use or gambling practice. After a descriptive analysis, a multivariate analysis was performed to identify the factors associated with unsuccessful OUDT. Results: The sample consisted of 263 patients. Prevalence of coaddictions reached 97% of the sample. Problem gambling was associated with 10% of the patients. OUDT was considered as "unsuccessful" for 60% of the patients. Associated factors included having drug-using friends, psychiatric and professional negative consequences related to opioid use, more than one OST-prescribing physician, and impulsivity, especially high scores for lack of premeditation and sensation seeking. Conclusions: This study provides further evidence of the need to consider coaddictions and the usefulness of global addictive evaluations. Poor prognostic factors must alert the clinician to initiate more sustained care. Further implications are discussed.
RESUMEN
AIMS: Our study aimed to evaluate the impacts of the cytochrome P450 (CYP) 2B6-G516T and CYP2D6 genetic polymorphisms on pharmacokinetic and clinical parameters in patients receiving methadone maintenance treatment. METHODS: Opioid PhArmacoLogy (OPAL) was a clinical survey of the sociodemographic characteristics, history and consequences of pathology associated with methadone maintenance treatment response and current addictive comorbidities. A subgroup of 72 methadone patients was genotyped. RESULTS: When comparing the three CYP2B6 genotype groups, the methadone (R)- and (S)-methadone enantiomer concentrations/doses (concentrations relative to doses) were different (P = .029, P = .0019). The CYP2D6 phenotypes did not seem to be relevant with regard to methadone levels. On multivariate analysis, neither the CYP2B6 genotype nor the CYP2D6 phenotype explained the (R)-methadone concentration/dose values (P = .92; P = .86); the (S)-methadone concentration/dose values (P = .052; P = .95 [although there was a difference between the TT group and GT and GG groups {P = .019}]); or opiate cessation (P = .12; P = .90). CONCLUSION: The genotyping of CYP2B6 G516T could be an interesting tool to explore methadone intervariability.

OBJECTIVES: Addictions are not restricted to substance-use disorders, and it is now widely recognized that they also include behavioral addictions. Certain individuals with eating disorders also experiment their disorder as an addiction. The objective was to identify typologies of patients presenting with various behavioral addictions or eating disorders according to their evolution within the framework of care, and to specify the factors associated with the differential clinical trajectories. METHODS: We included 302 patients presenting with problem gambling, sexual addiction, compulsive buying, excessive videogame use or eating disorders. The patients completed a multiaxial assessment through a face-to-face structured interview and self-administered questionnaires, including sociodemographic and addiction-related characteristics, psychiatric and addictive comorbidities and several psychological characteristics. The assessment was performed at inclusion and then repeated after 6 and 12 months. The statistical analysis included a combination of growth mixture models and latent class analysis. RESULTS: We identified five classes of patients with different profiles related to their trajectories during a one-year period of specialized care: "complex patients", "patients with impulsive psychological functioning", "patients with cooperative psychological functioning", "patients with immature psychological functioning," and "patients with resilient psychological functioning". CONCLUSIONS: The typology obtained brings interesting findings to propose patient-centered care strategies adapted to these disorders. Because the typology was independent from the type of disorder, it supports the general concept of behavioral addictions, and the similarities between eating disorders and behavioral addictions. The relevance of this model should be further examined in future studies.

Background Craving is a core symptom of addictive disorders, such as pathological gambling for example. Over the last decade, several studies have assessed the efficacy of repetitive transcranial magnetic stimulation (rTMS) in the addiction field, which triggers the dorsolateral prefrontal cortex (DLPFC) to decrease craving. The STIMJEU study investigated whether a single session of low-frequency (LF, i.e., 1 Hz) rTMS applied to the right DLPFC reduced cue-induced gambling craving in a sample of treatment-seeking pathological gamblers. Methods Thirty patients received both active and sham rTMS in random order and were blinded to the condition in a within-subject crossover design. Outcome measures included self-reported gambling craving (Visual Analog Scale and Gambling Craving Scale) and physiological measures (heart rate and blood pressure). Results The rTMS sessions were associated with a significant decrease in the gambling urge, regardless of whether the session was active or sham. When controlling cue-induced craving levels, no effects were observed on craving for active rTMS. Overall, rTMS was well-tolerated, and the credibility of the sham procedure was assessed and appeared to be appropriate. Conclusions We failed to demonstrate the specific efficacy of one session of LF rTMS to decrease cue-induced craving in pathological gamblers. A strong placebo-effect and rTMS parameters may partly explain these results. Yet, we are convinced that rTMS remains a promising therapeutic method. Further studies are required to examine its potential effect.

Impulse control disorders (ICDs) are a well-known adverse effect of dopamine agonists (DAAs). This critical review aims to summarize data on the prevalence and factors associated with the development of an ICD simultaneous to DAA use. A search of two electronic databases was completed from inception to July 2017. The search terms were medical subject headings (MeSH) terms including "dopamine agonists" AND "disruptive disorders", "impulse control disorders", or "conduct disorders". Articles had to fulfill the following criteria to be included: (i) the target problem was an ICD; (ii) the medication was a dopaminergic drug; and (iii) the article was an original article. Of the potential 584 articles, 90 met the criteria for inclusion. DAAs were used in Parkinson's disease (PD), restless legs syndrome (RLS) or prolactinoma. The prevalence of ICDs ranged from 2.6 to 34.8% in PD patients, reaching higher rates in specific PD populations; a lower prevalence was found in RLS patients. We found only two studies about prolactinoma. The most robust findings relative to the factors associated with the development of an ICD included the type of DAA, the dosage, male gender, a younger age, a history of psychiatric symptoms, an earlier onset of disease, a longer disease duration, and motor complications in PD. This review suggests that DAA use is associated with an increased risk in the occurrence of an ICD, under the combined influence of various factors. Guidelines to help prevent and to treat ICDs when required do exist, although further studies are required to better identify patients with a predisposition.

Compared to general population, pathological gamblers are 3.4 times more likely to attempt suicide. Our objective was to identify specific profiles of problem gamblers (PGs) with suicidal risk according to sociodemographic, clinical and gambling characteristics. The PGs cohort, called "EVALJEU" , consists in the inclusion of any new PG seeking treatment in our Department. Patients underwent a semi-structured clinical interview and completed self-report questionnaires. The "suicidal risk module" of the Mini International Psychiatric interview (MINI) allowed to constitute two groups of patients that were compared, according to the presence of a suicidal risk. A logistic regression was performed to identify factors related to suicidal risk in PGs. In our sample (N=194), 40.21% presented a suicidal risk. A history of major depression and anxiety disorders were predictors of suicidal risk as well as the perceived inability to stop gambling. Suicidality is a significant clinical concern in PGs. Therefore, three specific predictors, identified by our study, must be assessed.

BACKGROUND: In the last 10 years, dopamine replacement therapy (DRT) has become a well-known risk factor for developing an impulse control disorder, such as gambling disorder (GD). Another medication, aripiprazole (ARI), has been more recently identified as another risk factor. Dopamine replacement therapy and ARI share a dopamine agonist action. Our work aimed at comparing patients with PG according to their treatment with DRT or ARI. METHODS: Two methods were combined-a systematic review concentrated on case reports and the analysis of a French disordered gamblers cohort focused on patients using ARI or DRT at inclusion. RESULTS: We reported 48 cases of GD possibly due to DRT and 17 cases of GD possibly due to ARI. Because of their standardized assessment, only the EVALJEU patients could be compared. Two clinical patterns emerged. Patients in the ARI group were young, impulsive, and high novelty seekers and had a history of substance misuse. Their first gambling experience occurred during adolescence. Conversely, patients in the DRT group were old, and they began gambling late in life. They showed low levels of gambling-related cognition. CONCLUSIONS: Patients in the ARI group seemed to be more severe pathological gamblers than patients in the DRT group. Aripiprazole is a partial D2 receptor agonist, whereas DRT includes full D2 receptor agonist. The trigger mechanism of PG development is complex and cannot only be attributed only to the pharmacodynamic effects of dopaminergic drugs. Indeed, individual vulnerability factors and environmental factors need to be considered.

Studies have shown that Evening-Type (ET) subjects used more stimulating and sedative substances, and presented more psychiatric disorders than Morning-Type (MT) subject. However, there is a lack of data on the chronotype of patients with addiction. The aim of our study was to describe chronotype and associated factors in a sample of outpatients beginning treatment for addiction. Subjects were assessed with the Morningness-Eveningness questionnaire of Hörne & Ostberg, the Addiction Severity Index and the Mini International Neuropsychiatric Interview. In the 333 subjects with an addiction, 20% were MT and 32% were ET. When comparing ET to MT, multivariate analysis showed that ET was significantly associated with poly-problematic addiction, non-substance addictions, cannabis addiction, and mood disorders, but not with severity of addiction. MT was associated with antisocial personality disorder. Results suggested that chronotype was associated with specific addiction pattern and psychiatric disorders.
