“…The study found that adhd problem gamblers displayed subjacent shortages in reward learning (not found in adhd patients without gambling; Abouzari et al, 2016). Moreover, another investigation studied a group of young people (male and female) from a community sample, and the results were contrasted with subjects that had adhd -lifetime diagnosis (n = 46), non-diagnosed fellows with high-adhd-symptoms (n = 83), and non-diagnosed fellows with low adhd-symptom group (n = 84; Davis, Cohen, Davids, & Rabindranath, 2015).…”

“…3) Based on different studies, the main differences between subjects with comorbid gambling disorder and adhd, and their counterparts without adhd, is that the first ones have a marked tendency of: more severe gambling, more psychiatric comorbidities (Fatseas et al, 2016), earlier age of gambling conducts onset, higher impetuosity, higher caffeine consumption, poorer response restraint, impaired decision-making (Chamberlain et al, 2015), lower self-esteem, depressed mood, upper impulsivity, poorer personal control, greater levels of emotional instability, interpersonal sensitivity, stress proneness (Davtian et al, 2012), and augmented cognitive distortions . Moreover adhd subjects with gambling problems have limitations in reward learning (Abouzari et al, 2016). 4) Relating to treatment, the presence of adhd in a subject with gambling disorder implies more challenges for screening, assessment and treatment, according to different authors.…”

Purpose: For the present review, publications in the field of gambling disorder that deal with its relationships with others, mainly attention deficit hyperactivity disorder (adhd) and Parkinson's disease (pd) were consulted. Methods: The current revision includes a total of 63 references published between 1987 and 2017. It included human studies and revisions regarding the comorbidity of gambling disorder with adhd or pd. The search terms included: gambling disorder, gambling disorder comorbidity, gambling disorder and adhd, gambling disorder and pd, gambling disorder and impulsivity. The present review focused on the link among gambling disorder and adhd or pd, because there were a large number of publications related to these disorders. For organization purpose the current work was split into two main parts: 1) Revision of previous scientific reviews about gambling disorder, and 2) Overview and conclusions of experimental work about gambling disorder. Conclusions: The principal conclusions of the current review are: 1) subjects with a gambling disorder have a higher incidence of adhd (and also of attention deficit disorder [add]), 2) the presence of adhd in subjects that suffer of gambling disorder implies more challenges for the health care system, and 3) pd treatments that increase the agonism of dopamine type of receptor are related to an elevated probability for developing a gambling problem or an impulse control disorder.Keywords: adhd, comorbidity, disorder, dopamine receptor, gambling pd. ResumenObjetivo: para la presente revisión, se consultaron publicaciones en el campo de la ludopatía que tratan de sus relaciones con otros trastornos, principalmente el trastorno por déficit de atención con hiperactividad (tdah) y la enfermedad de Parkinson (ep). Método: la presente revisión tiene en cuenta 63 referencias publicadas entre 1987 y 2017 y tuvo en cuenta estudios en humanos y revisiones sobre la comorbilidad de la ludopatía con el tdah o la ep. Los términos de la búsqueda incluyeron: ludopatía, comorbilidad de la ludopatía, ludopatía y tdah, ludopatía y ep, ludopatía e impulsividad. Esta revisión se centró en el vínculo entre la ludopatía y el tdah o la ep, puesto que existía un gran número de publicaciones relacionadas con estos trastornos. Para su organización, el presente trabajo se dividió en dos partes principales: 1) el análisis de revisiones científicas anteriores sobre la ludopatía y 2) el resumen y las conclusiones del trabajo experimental sobre la ludopatía. Conclusiones: las conclusiones principales de esta revisión son: 1) los sujetos con ludopatía tienen una mayor incidencia del tdah (y también del trastorno de déficit de atención [tda]), 2) la presencia del tdah en sujetos que sufren de ludopatía implica más retos para el sistema de salud y 3) los tratamientos de la ep que aumentan el agonismo del receptor tipo dopamina están relacionados con una probabilidad elevada de desarrollar un problema de juego o un trastorno de control de impulsos.Palabras clave: tdah, comorbilidad, trasto...

“…The ERPs following the gamble selection in the Probability Gambling Task [52] are characterized by several wave components [82][83][84][85]. Few studies analyzed the ERPs in adult ADHD and showed that N2, P3a, P3b, feed-back related negativity and N400-like components distinguish ADHD and controls in association with the evaluation of the reward outcome [28,86] and with the emotional feelings generated by risk-taking attitude [41]. In our current paper, we did not observe group effects (i.e., differences between controls and ADHD) on the measurements of PGT due to the working memory training, other than on the response times ( Table 2).…”

Early Attentional Modulation by Working Memory Training in Young Adult ADHD Patients during a Risky Decision-Making Task

et al. 2020

Background: Working memory (WM) deficits and impaired decision making are among the characteristic symptoms of patients affected by attention deficit/hyperactivity disorder (ADHD). The inattention associated with the disorder is likely to be due to functional deficits of the neural networks inhibiting irrelevant sensory input. In the presence of unnecessary information, a good decisional process is impaired and ADHD patients tend to take risky decisions. This study is aimed to test the hypothesis that the level of difficulty of a WM training (WMT) is affecting the top-down modulation of the attentional processes in a probabilistic gambling task. Methods: Event-related potentials (ERP) triggered by the choice of the amount wagered in the gambling task were recorded, before and after WMT with a the dual n-back task, in young ADHD adults and matched controls. For each group of participants, randomly assigned individuals were requested to perform WMT with a fixed baseline level of difficulty. The remaining participants were trained with a performance-dependent adaptive n-level of difficulty. Results: We compared the ERP recordings before and after 20 days of WMT in each subgroup. The analysis was focused on the time windows with at least three recording sites showing differences before and after training, after Bonferroni correction ( p < 0.05 ). In ADHD, the P1 wave component was selectively affected at frontal sites and its shape was recovered close to controls’ only after adaptive training. In controls, the strongest contrast was observed at parietal level with a left hemispheric dominance at latencies near 900 ms, more after baseline than after adaptive training. Conclusion: Partial restoration of early selective attentional processes in ADHD patients might occur after WMT with a high cognitive load. Modified frontal sites’ activities might constitute a neural marker of this effect in a gambling task. In controls, conversely, an increase in late parietal negativity might rather be a marker of an increase in transfer effects to fluid intelligence.

“…Therefore, the magnitude of FRN in each single trail was convolved with the canonical HRF and then performed as a regressor in GLM. Meanwhile, recent studies have shown that there are differences in alpha‐band and theta‐band power under different feedback conditions and relative EEG power which approximated neglecting insignificant frequency bands characterizes the experimental task activity better than the absolute power (Abouzari, Oberg, & Tata, ). So, the relative alpha‐band and theta‐band power of each trial over FCz electrode during 200‐350 ms time period after feedback onset was also extracted as regressors.…”

BackgroundExecutive function refers to conscious control in psychological process which relates to thinking and action. Emotional decision is a part of hot executive function and contains emotion and logic elements. As a kind of important social adaptation ability, more and more attention has been paid in recent years.ObjectiveGambling task can be well performed in the study of emotional decision. As fMRI researches focused on gambling task show not completely consistent brain activation regions, this study adopted EEG‐fMRI fusion technology to reveal brain neural activity related with feedback stimuli.MethodsIn this study, an EEG‐informed fMRI analysis was applied to process simultaneous EEG‐fMRI data. First, relative power‐spectrum analysis and K‐means clustering method were performed separately to extract EEG‐fMRI features. Then, Generalized linear models were structured using fMRI data and using different EEG features as regressors.ResultsThe results showed that in the win versus loss stimuli, the activated regions almost covered the caudate, the ventral striatum (VS), the orbital frontal cortex (OFC), and the cingulate. Wide activation areas associated with reward and punishment were revealed by the EEG‐fMRI integration analysis than the conventional fMRI results, such as the posterior cingulate and the OFC. The VS and the medial prefrontal cortex (mPFC) were found when EEG power features were performed as regressors of GLM compared with results entering the amplitudes of feedback‐related negativity (FRN) as regressors. Furthermore, the brain region activation intensity was the strongest when theta‐band power was used as a regressor compared with the other two fusion results.ConclusionsThe EEG‐based fMRI analysis can more accurately depict the whole‐brain activation map and analyze emotional decision problems.
