The combination of donepezil and cognitive training for improving treatment outcomes for alcohol use disorder: Design of a randomized controlled trial. Contemp Clin Trials 2024; 145:107657. [PMID: 39111388 DOI: 10.1016/j.cct.2024.107657] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/10/2023] [Revised: 07/13/2024] [Accepted: 08/03/2024] [Indexed: 08/10/2024]
Abstract
BACKGROUND The development of alcohol use disorder (AUD) is a major concern in public health, and cognitive impairments caused by alcohol are involved in this process. Emerging neurobiological evidence suggests that donepezil, an anticholinesterase agent, may improve AUD treatment outcomes by enhancing neurocognitive functioning. Previous research has also suggested that cognitive remediation therapy (CRT) could potentially improve cognitive function and AUD treatment outcomes. We present the rationale and design of a trial to evaluate the combination of donepezil and cognitive remediation therapy (donepezil + CRT) as an intervention for AUD. METHODS We propose a 13-week, randomized, double-blind, placebo-controlled, between-subjects trial comparing 4 groups (donepezil + CRT vs. donepezil alone vs. CRT alone vs. placebos) as an intervention for AUD. The main goal of the study is to evaluate if donepezil + CRT is superior to placebo in reducing heavy drinking days and improving neurocognitive functioning. A total of 160 patients (4 groups, 40 per each group) with AUD between the ages of 18-80 years will be recruited at Yale University and the VA Connecticut Healthcare System. Primary outcome measures include 1) heavy drinking by Timeline Follow Back (TLFB) over 13 weeks and 2) global neurocognitive functioning by a global index of neurocognitive function score at 7 and 13 weeks. DISCUSSION This protocol paper describes the rationale and proposed methods for the randomized controlled trial for improving AUD treatment outcomes. This project has significant clinical potential to help patients suffering from AUD by improving their cognition and reducing alcohol consumption. TRIAL REGISTRATION NCT05042102.

Neuropsychopharmacology 2024:10.1038/s41386-024-01882-7. [PMID: 38760425 DOI: 10.1038/s41386-024-01882-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/04/2024] [Revised: 04/26/2024] [Accepted: 04/29/2024] [Indexed: 05/19/2024]
Abstract
Considerable research has suggested that certain cognitive domains may contribute to cocaine misuse. However, there are gaps in the literature regarding whether cognitive performance before drug exposure predicts susceptibility to cocaine self-administration and how cognitive performance relates to future cocaine intake. Thus, the present study aimed to examine cognitive performance, as measured using automated CANTAB cognitive battery, prior to and following acquisition of cocaine self-administration under a concurrent drug vs. food choice procedure in female and male socially housed cynomolgus macaques. The cognitive battery consisted of measures of associative learning (stimulus and compound discrimination tasks), behavioral flexibility (intradimensional and extradimensional tasks), and behavioral inhibition (stimulus discrimination reversal, SDR, and extra-dimensional reversal tasks). After assessing cognitive performance, monkeys were trained to self-administer cocaine (saline, 0.01-0.1 mg/kg/injection) under a concurrent cocaine vs. food schedule of reinforcement. After a history of cocaine self-administration across 3-4 years, the cognitive battery was re-assessed and compared with sensitivity to cocaine reinforcement. Results showed drug-naïve monkeys that were less accurate on the SDR task, measuring behavioral inhibition, were more sensitive to cocaine reinforcement under the concurrent cocaine vs. food choice procedure. Furthermore, following chronic cocaine self-administration, cocaine intake was a negative predictor of accuracy on the SDR behavioral inhibition task. After cocaine maintenance, monkeys with higher cocaine intakes required more trials to complete the SDR behavioral inhibition task and made more incorrect responses during these trials. No sex or social rank differences were noted. Overall, these findings suggest that cognitive performance may influence vulnerability to cocaine misuse. Also, chronic cocaine may decrease levels of behavioral inhibition as measured via the SDR task in both females and males.

Abstract
BACKGROUND The association between polysubstance use disorder (pSUD), mental illness, and cognitive impairments is well established and linked to negative outcomes in substance use disorder treatment. However, it remains unclear whether cognitive impairment predicts long-term psychological distress among treatment seeking patients with pSUD. This study aimed to investigate the associations and predictive ability of cognitive impairment on psychological distress one and 5 years after treatment initiation. METHODS N = 164 treatment seeking patients with pSUD were sampled at treatment initiation. We examined associations between cognitive impairment according to Montreal Cognitive Assessment® (MoCA®), Wechsler Abbreviated Scale of Intelligence (WASI), and Behaviour Rating Inventory of Executive Function - Adult version (BRIEF-A) administered at treatment initiation and psychological distress defined by the Symptom Check List-90-Revised (SCL-90-R) at treatment initiation, one and five years later. We ran hierarchical logistic regressions to assess the predictive ability of the respective cognitive instruments administered at treatment initiation on psychological distress measured one and five years later including psychological distress at treatment initiation and substance intake at the time-points of the measurements as covariates. RESULTS The main results was that MoCA® and BRIEF-A predicted psychological distress at years one and five, but BRIEF-A lost predictive power when accounting for psychological distress at treatment initiation. WASI predicted psychological distress at year one, but not at year five. CONCLUSIONS Results from MoCA® and WASI was found to be less sensitive to the effect of psychological distress than BRIEF-A. Cognitive impairment at treatment initiation may hold predictive value on later psychological distress, yet its clinical utility is uncertain.

Abstract
INTRODUCTION Cognitive impairments among patients with substance use disorders are prevalent and associated with adverse treatment outcomes. However, knowledge of the predictive value of broad cognitive screening instruments on long-term treatment outcomes is limited. The present study aimed to examine the predictive value of measures from the Montreal Cognitive Assessment® (MoCA®), Wechsler Abbreviated Scale of Intelligence (WASI), and the Behaviour Rating Inventory of Executive Function - Adult version (BRIEF-A) on self-reported long-term substance use and abstinence in patients with polysubstance use disorders (pSUD). METHODS A cohort (N = 164) of patients with pSUD who started a new treatment sequence in the Stavanger University Hospital catchment area were recruited and followed prospectively for 5 years. Participants completed neurocognitive testing with the MoCA®, WASI, and BRIEF-A at inclusion and were categorized as cognitively impaired or non-impaired according to recommended cut-off values. The sum score of the items from the Drug Use Disorders Identification Test Consumption scale (DUDIT-C) was used as a measure of substance use outcome 1 and 5 years after inclusion. We defined substance abstinence (DUDIT-C = 0) and heavy substance use (DUDIT-C ≥7) to determine whether cognitive impairments measured by the respective instruments were associated with and could predict abstinence and heavy substance use 1 and 5 years after baseline. RESULTS At the 1-year follow-up, 54% of the total sample reported total abstinence from substances. Conversely, 31% presented heavy substance use. At 5 years, 64% of the total sample reported abstinence from substances, while 25% presented heavy substance use. The results showed a statistically significant association between cognitive impairment defined from MoCA® and higher continuous scores on DUDIT-C at 1-year follow-up. There were no differences in substance abstinence or heavy substance use between patients with and without cognitive impairment at the 1- and 5-year follow-ups. Furthermore, cognitive impairment did not explain substance abstinence or heavy substance use at the 1- and 5-year follow-ups. CONCLUSION Generally, individuals with pSUD may be burdened and lack psychosocial resources to such an extent that cognitive functioning plays a subordinate role in long-term recovery. The present study suggests that results on screening tools assessing broad cognitive domains at treatment initiation have limited clinical value in predicting long-term substance use outcomes. There is a need to establish clinically viable instruments to assess cognitive functions with well-established clinical and ecological validity in the SUD population.

Abstract
In the last decade, alcohol consumption in the US has risen by 84% in women compared with 35% in men. Furthermore, research has shown that sex- and gender-related differences may disadvantage women in terms of developing a range of psychological, cognitive, and medical problems considerably earlier in their drinking history than men, and despite consuming a similar quantity of substances. While this "telescoping" process has been acknowledged in the literature, a concomitant understanding of the underlying biobehavioral mechanisms, and an increase in the development of specific treatments tailored to women, has not occurred. In the current chapter we focus on understanding why the need for personalized, sex-specific medications is imperative, and highlight some of the potential sex-specific gonadal and stress-related adaptations underpinning the accelerated progress from controlled to compulsive drug and alcohol seeking in women. We additionally discuss the efficacy of these mechanisms as novel targets for medications development, using exogenous progesterone and guanfacine as examples. Finally, we assess some of the challenges faced and progress made in terms of developing innovative medications in women. We suggest that agents such as exogenous progesterone and adrenergic medications, such as guanfacine, may provide some efficacy in terms of attenuating stress-induced craving for several substances, as well as improving the ability to emotionally regulate in the face of stress, preferentially in women. However, to fully leverage the potential of these therapeutics in substance-using women, greater focus needs to the placed on reducing barriers to treatment and research by encouraging women into clinical trials.

Abstract
BACKGROUND Long-term opioid and amphetamine-type stimulants (ATS) abuse may affect immunological function and impair executive function. We aimed to determine whether biomarkers of inflammation and executive function were associated with substance use in individuals with opioid use disorder (OUD) and ATS use disorder (ATSUD). The interactions between these biomarkers were also explored. METHODS We assessed plasma cytokines [tumor necrosis factor (TNF)-α, C-reactive protein (CRP), interleukin (IL)-8, IL-6, transforming growth factor (TGF)-β1, brain-derived neurotrophic factor (BDNF), and executive function in terms of the Wisconsin Card Sorting Test (WCST) and Continuous Performance Test (CPT) in OUD and ATSUD patients and healthy controls (HC). OUD and ATSUD patients were followed for 12 weeks, and their urine morphine and amphetamine tests, cytokine levels, and executive function were repeatedly measured. RESULTS We enrolled 483 patients and 145 HC. Plasma TNF-α, CRP, IL-8, IL-6, and BDNF levels and most subscale scores on the WCST and CPT significantly differed between OUD and ATSUD patients and HC. Increased TNF-α levels and more perseveration error on the WCST were significantly associated with more urine drug-positive results and less abstinence. Plasma IL-6 and CRP levels were significantly negatively correlated with WCST and CPT performance. CONCLUSION OUD and ATSUD patients had more inflammation and worse executive function than HC. Inflammatory markers and WCST performance were associated with their urinary drug results, and higher inflammation was associated with poor executive function. Studies on regulating the inflammatory process and enhancing executive function in OUD and ATSUD are warranted.

Abstract
Background and rationale. Severe alcohol use disorder (SAUD) is a major public health concern, given its massive individual, interpersonal, and societal consequences. The available prevention and treatment programs have proven limited effectiveness, as relapse rates are still high in this clinical population. Developing effective interventions reducing the appearance and persistence of SAUD thus constitutes an experimental and clinical priority. Among the new therapeutic approaches, there is a growing interest for noninvasive neuromodulation techniques, and particularly for transcranial direct current stimulation (tDCS) as an adjunctive treatment in neuropsychiatric disorders, including SAUD. Methods. We propose a systematic review, based on preferred reporting items for systematic reviews and meta-analyses (PRISMA) guidelines, evaluating the available evidence on the effectiveness of tDCS to improve clinical interventions in SAUD. Results. We provide an integrative overview of studies applying tDCS in clinical populations with SAUD, together with a standardized methodological quality assessment. We show that the currently available data remain inconsistent. Some data suggested that tDCS can (1) reduce craving, relapse or alcohol-cue reactivity and (2) improve cognitive control and inhibition. However, other studies did not observe any beneficial effect of tDCS in SAUD. Conclusions. Capitalizing on the identified strengths and shortcomings of available results, we present evidence-based clinical guidelines to integrate tDCS in current clinical settings and to combine it with neurocognitive training.

Abstract
INTRODUCTION Rural older adults are an underserved population with high rates of smoking and related morbidity and mortality. Age-related executive function deficits are common in older smokers; however, the association of depression and nicotine dependence on executive function has not been explored. This study addressed whether depression and nicotine dependence are related to executive dysfunction in rural older adult smokers. METHODS The sample included 40 rural older adults recruited from two primary care clinics in North Carolina. Executive function was evaluated with the Behavioral Regulation Index (BRI), Metacognition Index, and Global Executive Composite (GEC) T scores from the Behavior Rating Inventory of Executive Function-Adult. Nicotine dependence and depression symptoms were assessed using the Fagerstrom Test and Center for Epidemiologic Depression Scale-10, respectively. Analysis of variance was used to explore whether depression and/or nicotine dependence influences executive function. Nondirectional tests were performed with significance set at .10. RESULTS Smokers who screened positive for depression had significantly greater executive dysfunction than those who did not (BRI: p = .0003, Metacognition Index: p < .0001, GEC: p < .0001), and moderate/high dependence was associated with greater executive function deficits compared with those with mild dependence (BRI: p = .0942). Together, depression and nicotine dependence explained 50% of the variability of the GEC overall scores. CONCLUSIONS Executive dysfunction is common in rural older adult smokers and associated with depression and nicotine dependence severity. Futures studies should test the relationship of executive function and smoking cessation in the older adult population as it may have implications for cessation in this population.

Abstract
Purpose of Review
Maternal prenatal substance use presents a multilevel risk to child development and parenting. Although parenting interventions are increasingly integrated into substance use treatment, prenatal parenting processes have not received equal attention within these interventions. This article aims to synthesize the evidence on the specific prenatal risk factors affecting the development of early parenting of substance-using mothers, as well as interventions focusing on those factors.
Recent Findings
Both neurobiological and psychosocial risk factors affect the prenatal development of parenting in the context of maternal substance use. Maternal–fetal attachment, mentalization, self-regulation, and psychosocial risks are important in treatment and highly intertwined with abstinence. Although parenting interventions seem to be highly beneficial, most studies have not differentiated between pre- and postnatal interventions or described pregnancy-specific intervention elements.
Summary
Due to the salience of pregnancy in treating substance-using parents, interventions should begin prenatally and include pregnancy-specific parenting focus. Further research on prenatal interventions is warranted.

Abstract
The Relational Theory of Addiction hypothesizes that women's substance abuse SUD development and (SA) recovery experiences differ from men's because of women's tendency to form nested self-concepts and increased relative desire for close interpersonal connections. We suggest that these two differences may have a dynamic and complex influence on recovery success, particularly for women living in group sober homes. This project uses Relational and Social Cognitive Theories as theoretical springboards to investigate the link between Tendency to Engage in Automatic Negatively Affected Social Comparisons (TEANSAC) and Sober Housemate Harmony (SHH) on women's individual perceptions of Abstinence Specific Self-Efficacy (ASSE). We administered short surveys to women (N = 25) that had recently left inpatient SA treatment and were currently living in a group sober home to assess TEANSAC, SHH and ASSE. Results illustrated that higher TEANSAC scores predicted lower ASSE scores. However, SHH did not predict ASSE scores. Finally, an interaction effect was found in which SHH moderated the relationship between TEANSAC and ASSE. Specifically, we found that highly harmonious sober homes may buffer against the negative effects of increased TEANSAC scores. This project suggests that social cognitive and interpersonal variables may be important factors to consider for women's long-term recovery success.

Abstract
Substance use disorders are associated with diverse neuropsychological impairments, with deficits in memory and executive functioning commonly observed. Cognitive remediation has been shown to be effective in other populations with cognitive impairments in these domains, including those with psychiatric disorders and acquired brain injuries, and it has been hypothesised to be similarly effective for those in treatment for substance use disorders. We aimed to systematically review the evidence for cognitive remediation interventions administered as an adjunct treatment to substance use rehabilitation. Studies were included if participants were receiving substance use treatment, if improving cognitive functioning was the main focus of the intervention and if they used an experimental design with a control condition receiving treatment-as-usual or an active control intervention. Two independent reviewers agreed on the final selection of 32 studies, encompassing cognitive remediation for working memory, memory, executive functioning and general cognition. Significant differences between intervention and control groups for cognitive test results and treatment outcomes were extracted and compared across treatment approaches. The review found considerable heterogeneity across studies, including in the types of interventions, the nature of participants and the outcome measures used. Further, a lack of quality studies with sufficient power meant that limited conclusions could be drawn, highlighting a need for further replication and research. However, findings indicate that cognitive remediation remains a promising potential avenue for improving cognition and treatment outcomes for those in treatment for substance use disorders.

Abstract
Effectiveness of interventions for violent behaviour may be undermined by the presence of neurocognitive impairment, which is known to be common among alcohol and other drug (AOD) users and violent offenders. The current study aimed to examine whether the cognitive functioning of individuals with AOD histories presenting to a specialist addiction neuropsychology service differed according to their offending history (i.e. non-offending, non-violent offending and violent offending), using a retrospective case file audit design. Data were extracted from 190 clients. Tests assessed a breadth of cognitive domains. Violent offenders demonstrated the lowest premorbid IQ out of the three groups, and a significantly higher proportion of violent offenders presented with impaired divided attention and impaired cognitive inhibition compared to non-violent offenders. Rates of impairment across groups were well beyond those expected within the general population. Delivery of both AOD and violence interventions should be adapted to accommodate individuals' cognitive difficulties.

Abstract
Behavioral weight loss programs combining energy restriction and increased physical activity (PA) are generally successful in producing clinically significant weight loss (≥5%) over 3-6 mos. However, weight maintenance (≥ 2 yrs.) continues to be problematic, due in part to an inability of individuals to continue adherence to diet and PA recommendations. It is hypothesized that neurocognitive processes, specifically executive functions (EFs, i.e., inhibition, working memory, mental flexibility), underlie self-regulation, self-efficacy, and are essential for the adoption and maintenance of health behaviors. Behavioral weight loss programs generally attempt to improve self-regulation; however, these skills are difficult to implement long-term. Strengthening EFs through cognitive training may improve weight maintenance by improving self-efficacy and self-regulation, resulting in improved program attendance and improved adherence to dietary and PA recommendations. Although randomized trials have not been conducted to specifically evaluate this hypothesis, results from the available literature suggest the potential for cognitive training to improve weight maintenance.

Abstract
Objective: To determine the prevalence and associated demographic and clinical features of borderline intellectual functioning (BIF) among individuals with polysubstance use disorder (pSUD). Methods: We applied a cross-sectional analytical design to data from the Norwegian STAYER study (n = 162), a cohort study of patients with a pSUD from the Stavanger University hospital catchment area. We used Wechsler Abbreviated Scale of Intelligence Full Scale IQ (FSIQ) to define BIF (FSIQ = 70-85) and non-BIF (FSIQ = >85) and collected demographic and clinical data using semi-structured interviews and self-reports on the Symptom Checklist 90-Revised (SCL-90-R) and the Satisfaction With Life Scale (SWLS). Results: The prevalence of BIF was 18% in the present study. The presence of BIF was associated with higher SCL-90-R GSI scores than in the non-BIF group. There were no significant differences between the BIF and non-BIF groups regarding age, gender, participation in meaningful daily activity, years of work experience, years of education, satisfaction with life, level of care, treatment attempts, age at substance-use onset, years of substance use, history of injecting drugs, or age of onset of injecting drugs. Conclusion: The present study confirmed a higher prevalence of BIF among patients with pSUD than expected from the distribution of IQ scores in a general population. Elevated SCL-90-R GSI scores suggested that BIF is associated with increased psychological distress in patients receiving treatment for pSUD. Further studies on this association, and its effect on treatment procedure and outcomes are strongly warranted.

Abstract
Alcohol-related cognitive impairment (ARCI) is highly prevalent among patients with alcohol dependence. Although it negatively influences treatment outcome, this condition is underdiagnosed and undertreated. The aim of this systematic review is to investigate the existing evidence regarding both cognitive and pharmacological interventions for ARCI. We systematically reviewed PubMed, Scopus and Science direct databases up to May 2019 and followed the PRISMA guidelines. The quality of the studies was assessed using the Jadad Scale. Twenty-six studies were eligible for inclusion (14 referring to neuropsychological interventions and 12 to pharmacological treatments). Among neuropsychological interventions, computerised treatments, errorless learning and component method showed positive effects on working memory, memory measures and general cognitive function. On the other hand, thiamine, memantine and methylphenidate improved working memory, long-term memory and general cognitive function. Nevertheless, these studies have several limitations, such as small sample size, lack of replication of the results or low specificity of the interventions. Therefore, no gold-standard intervention can yet be recommended for clinical practice, and further research based on promising strategies (e.g. digital interventions, thiamine) is required.

Abstract
Cognitive training results in significant, albeit modest, improvements in specific cognitive functions across a range of mental illnesses. Inhibitory control, defined as the ability to stop the execution of an automatic reaction or a planned motor behavior, is known to be particularly important for the regulation of health behaviors, including addictive behaviors. For example, several studies have indicated that inhibitory training can lead to reduced alcohol consumption or a loss of weight/reduced energy intake. However, the exact neurocognitive mechanisms that underlie such behavioral changes induced by training are still matter of debate. In the present study, we investigated the long-term impact (ie, at 1 week posttraining) of an inhibitory training program (composed of 4 consecutive daily training sessions of 20 minutes each) on the performance of a Go/No-go task. Healthy participants were randomly assigned to 1 of 3 designated groups: (1) an Inhibition Training (IT) group that received training based on a hybrid flanker Go/No-go task; (2) a group that received a noninhibition-based (ie, episodic memory; EM) training; and (3) a No-Training (NT) group to control for test-retest effects. Each group underwent 3 sessions of a Go/No-go task concomitant with the recording of event-related potentials. Our results revealed a specific impact of the Inhibitory Training on the Go/No-go task, indexed by a faster process compared with the other 2 groups. This effect was neurophysiologically indexed by a faster N2 component on the difference NoGo-Go waveform. Importantly, effects at both the behavioral and at the neural level were still readily discernible 1 week posttraining. Thus, our data clearly corroborate the notion that cognitive training is effective, while also indicating that it may persist over time.

Abstract
Minority stress is associated with emotional, cognitive, and health consequences for sexual minority individuals. Mechanisms remain poorly understood. Theory and preliminary evidence suggests that stress associated with minority identity results in negative emotions and attempts at suppression, which may contribute to depletion of executive function. This study was an experimental investigation of gay and lesbian adults (N = 141). Participants engaged in a stressful interpersonal task with a confederate with anti-gay or pro-gay attitudes. We examined how condition affected executive function, along with potential mediators (state anger, anxiety, expressive suppression). Contrary to hypotheses, participants in the anti-gay condition showed better postmanipulation cognitive performance than the pro-gay condition. This effect was partially mediated by anger. Participants in the anti-gay condition reported greater attempts at suppression, but this variable did not emerge as a mediator. This study was the first to experimentally manipulate exposure to anti-gay attitudes and measure effects on executive function.

Abstract
Substance use disorders are chronic, relapsing, and harmful conditions characterized by executive dysfunction. While there are currently no approved pharmacotherapy options for stimulant and cannabis use disorders, there are several evidence-based options available to help reduce symptoms during detoxification and aid long-term cessation for those with tobacco, alcohol and opioid use disorders. While these medication options have shown clinical efficacy, less is known regarding their potential to enhance executive function. This narrative review aims to provide a brief overview of research that has investigated whether commonly used pharmacotherapies for these substance use disorders (nicotine, bupropion, varenicline, disulfiram, acamprosate, nalmefene, naltrexone, methadone, buprenorphine, and lofexidine) effect three core executive function components (working memory, inhibitory control and cognitive flexibility). While pharmacotherapy-induced enhancement of executive function may improve cessation outcomes in dependent populations, there are limited and inconsistent findings regarding the effects of these medications on executive function. We discuss possible reasons for the mixed findings and suggest some future avenues of work that may enhance the understanding of addiction pharmacotherapy and cognitive training interventions and lead to improved patient outcomes.

Abstract
Background: In order to improve the current treatment of addictive disorders non-invasive neuromodulation over the dorsolateral prefrontal cortex (DLPFC) has gained attention. The DLPFC is crucially involved in executive functioning, functions which are related to the course of addictive disorders. Non-invasive stimulation of the DLPFC may lead to changes in executive functioning. Currently an overview of effects of neuromodulation on these functions is lacking. Therefore, this systematic review addresses the effects of non-invasive neuromodulation on executive functioning in addictive disorders. Methods: The current review is conducted and reported in accordance with the Preferred Reporting Items for Systematic reviews and Meta-Analyses for Protocols 2015 (PRISMA-P 2015) guidelines and has been registered in PROSPERO International Prospective Register of Systematic Reviews (https://www.crd.york.ac.uk/prospero/, registration number: CRD42018084157). Original articles were searched using the Ovid MEDLINE, Embase and PsycINFO database. Results: The systematic search resulted in 1,228 unique studies, of which sixteen were included in the current review. Some of these studies do not address the classic definition of executive functions, but another cognitive function. However, they were included in this review since the field is small and still under development and we aim to give an inclusive overview in its broadest sense. The following executive and other cognitive functioning domains were assessed: attention, cognitive flexibility, response inhibition, memory and learning, problem solving, social cognition, risk taking, cognitive bias modification and overall executive functioning. The executive function domain most positively affected was social cognition followed by memory & learning, response inhibition, cognitive flexibility and attention. Conclusions: The studies addressed in the current review used a large variability of stimulation protocols and study designs which complicates comparability of the results. Nevertheless, the results of these studies are promising in light of improvement of current treatment. Therefore, we recommend future studies that compare the effect of different types of stimulation, stimulation sides and number of stimulation sessions in larger clinical trials. This will significantly increase the comparability of the studies and thereby accelerate and clarify the conclusion on whether non-invasive neuromodulation is an effective add-on treatment for substance dependence.

Abstract
Low executive function (EF) and depression are each determinants of health. This study examined the synergy between deficits in EF (impaired cognitive flexibility; >75th percentile on the Wisconsin Card Sorting Test perseverative error score) and depressive symptoms (modified Centers for Epidemiologic Studies-Depression) and preincarceration well-being among incarcerated African American men ( N = 189). In adjusted analyses, having impaired EF and depression was strongly associated with pre-incarceration food insecurity (odds ratio [ OR] = 3.81, 95% confidence interval [CI] = [1.35, 10.77]), homelessness ( OR = 3.00, 95% CI [1.02, 8.80]), concern about bills ( OR = 3.76, 95% CI [1.42, 9.95]), low significant other support ( OR = 4.63, 95% CI [1.62, 13.24]), low friend support ( OR = 3.47, 95% CI [1.30, 9.26]), relationship difficulties ( OR = 2.86, 95% CI [1.05, 7.80]), and binge drinking ( OR = 3.62, 95% CI [1.22, 10.80]). Prison-based programs to treat depression and improve problem-solving may improve postrelease success.

Abstract
Substance use disorders (SUDs) remain problematic as many individuals are untreated or do not benefit from the currently available interventions. Thus, there is an urgent need to develop novel pharmacological interventions to treat SUDs. Evidence suggests that the female sex hormone, progesterone, attenuates the craving for and the euphoric effects of drugs of abuse. Research to date has demonstrated that progesterone may modulate responses to drugs of abuse and may have utility as a novel treatment for SUDs. A literature search was conducted to identify and examine studies that administered exogenous progesterone. Sixteen publications were identified, exploring the utility of exogenous progesterone or its metabolite, allopregnanolone, among a range of substances, including amphetamines (one study), benzodiazepines (one study), cocaine (nine studies), and tobacco/nicotine (five studies). Results indicated that exogenous progesterone and, its metabolite allopregnanolone, demonstrated preliminary efficacy as a treatment for substance use in both men and women. Notably, progesterone appears to target negative affect and augment cognitive functioning, especially among female substance users. Additional research is needed to explore the potential use of exogenous progesterone and allopregnanolone in the treatment of SUDs, including that associated with alcohol and opioids, but considering the current promising findings, exogenous progesterone and allopregnanolone may have utility as novel pharmacological treatments for SUDs.

Abstract
There has been little research about deleterious effects, including cognitive impairment, related to hazardous long-term alcohol use in old adults. This study aims to assess cognitive decline in old patients with alcohol use disorder and changes in cognitive state at 6 months follow-up, achieving or not abstinence. A six-month follow-up study was conducted in an outpatient center in Barcelona on a sample of old adults (≥65 years old) who had hazardous alcohol use. The sample was compared with healthy volunteers adjusted for age, sex and years of education. A neuropsychological protocol was performed at baseline and after 6 months follow-up covering four cognitive domains: attention, visuospatial abilities, memory and executive functions. Several domains were significant impaired at baseline: visual immediate and delayed recall, working memory, immediate verbal learning, total words learned, set switching and sustained attention. At 6 months reassessment, alcohol abstinence was achieved in 93.5% of patients and it was detected a trend towards improvement in direct mean scores of all cognitive areas, although it was not significant. The current study points out a cognitive impairment in many areas secondary to alcohol long-term hazardous use in old adults. A trend towards cognitive improvement after recovery was detected in most patients.

Abstract
Cognitive dysfunction is commonly observed among individuals with alcohol use disorder (AUD) and trauma exposure and is, in turn, associated with worse clinical outcomes. Accordingly, disruptions in cognitive functioning may be conceptualized as a trans-disease phenomenon representing a potential high-yield target for intervention. Less is known though about how different cognitive functions covary with alcohol use, craving, and post-traumatic stress symptom severity among trauma-exposed individuals with AUD. Sixty-eight male and female trauma-exposed military veterans with AUD, entering treatment trials to reduce alcohol use, completed measures assessing alcohol use and craving, post-traumatic stress symptom severity, and cognitive functioning. In multivariate models, after controlling for post-traumatic stress symptom severity, poorer learning and memory was associated with higher alcohol consumption and higher risk taking/impulsivity was associated with stronger preoccupations with alcohol and compulsions to drink. Alcohol consumption and craving, but not performance on cognitive tests, were positively associated with post-traumatic stress symptom severity. Findings suggest that interventions to strengthen cognitive functioning might be used as a preparatory step to augment treatments for AUD. Clinicians are encouraged to consider a standard assessment of cognitive functioning, in addition to post-traumatic stress symptom severity, in treatment planning and delivery for this vulnerable and high-risk population.

Abstract
Aim: To examine the efficacy of cognitive rehabilitation treatment (CRT) for people with opioid use disorder who were recruited into a methadone maintenance treatment (MMT) programme. Method: 120 male subjects were randomly assigned to (1) MMT plus CRT in two months or (2) MMT plus a control intervention. Subjects were assessed at the beginning, mid-point and post-intervention as well as at 1-, 3- and 6-month follow-up time points. Results: Analysis with repeated measure ANOVA showed that the CRT group performed significantly better in tests of learning, switching, processing speed, working memory and memory span. Moreover, the CRT group had significantly lower opiate use over the control group during 3-months follow-up. Analysis including only those with a history of methamphetamine use showed that the CRT group had significantly lower amphetamine use. No group differences were observed for treatment retention. Conclusions: Our findings provide evidence that adding CRT as an adjunct intervention to MMT can improve cognitive performance as well as abstinence from both opiates and stimulants.

Abstract
BACKGROUND Historically, substance misuse has been a serious problem faced by worldwide military personnel. Some research showed that military personnel have higher rates of unhealthy substance use than their age peers in the general population. These problems have serious consequences and may lead to significant military difficulties in the field of readiness, discipline, and mental or physical health. In this review, we gathered various methods for prevention, diagnosis, and treatment of substance use disorders and suggested a comprehensive plan for Iran Armed Forces to improve existing services. MATERIALS AND METHODS This article is a narrative review study, which was carried out on 2016. A careful literature review was performed between January 1970 and April 2016 on several national and international databases. Articles were screened according to the following inclusion criteria: (1) review articles about prevention and treatment protocols, (2) executive guidance, (3) cohort articles about risk factors of addiction, and (4) randomized controlled trials about prevention or treatment of substance use disorders in army service members. After screening by title and abstract, 130 articles selected of 832 founded articles, and after quality assessment, finally, 63 articles included in the review. RESULTS There is a necessity to manage substance use disorder through prevention, screening, and then referral to proper services for diagnosis and treatment. Urinalysis programs for screening are cost-effective and should be considered as a main method. Effective treatment includes both behavioral and pharmacological methods. CONCLUSIONS The ideal prevention program will include multiple and mutually reinforcing evidence-based universal, selective, and indicated attempts at both the individual and environmental levels. The implementation of screening and treatment strategies needs strict rules and national guideline for the comprehensive management of substance use disorders in army.

Abstract
Patient activation, the perceived capacity to manage one’s health, is positively associated with better health outcomes and lower costs. Underlying characteristics influencing patient activation are not completely understood leading to gaps in intervention strategies designed to improve patient activation. We suggest that variability in executive functioning influences patient activation and ultimately has an impact on health outcomes. To examine this hypothesis, 440 chronically ill Medicaid enrollees completed measures of executive functioning, patient activation, and health-related quality of life. Mediation analyses revealed that executive functioning: (a) directly affected patient activation and mental health-related quality of life, (b) indirectly affected mental health-related quality of life through patient activation, and (c) was unrelated to physical health-related quality of life. These data indicate that further study of the relationships among neurocognitive processes, patient activation, and health-related quality of life is needed and reinforces previous work demonstrating the association between patient activation and self-reported outcomes.

Abstract
OBJECTIVE Cognitive remediation therapy (CRT) is reported to improve neurocognitive and substance use disorder (SUD) outcomes in residential treatments. This National Institute of Drug Abuse funded pilot study reports on CRT as an augmentation to outpatient treatment for SUD. METHOD Recovering outpatient veterans were randomized into CRT + Work Therapy (n = 24) or work therapy (n = 24) with treatment-as-usual. Blind assessments of neurocognition and substance use were performed at baseline, 3 months (end of treatment), and 6-month follow-up. RESULTS Baseline assessments revealed high rates of cognitive impairment with 87.5% showing significant decline from premorbid IQ on at least 1 measure (median = 3/14 measures). Adherence to treatment was excellent. Follow-up rates were 95.7% at 3 months and 87.5% at 6 months. Mixed effects models of cognitive change over time revealed significant differences favoring CRT + Work Therapy on working memory (WM) and executive function indices. Global index of cognition showed a nonsignificant trend (effect size [ES] = .37) favoring CRT + Work Therapy. SUD outcomes were excellent for both conditions. CRT + Work Therapy had a mean of 97% days of abstinence at 3 months, 94% in the 30 days prior to 6-month follow-up, and 24/26 weeks of total abstinence; differences between conditions were not significant. CONCLUSIONS AND IMPLICATIONS FOR PRACTICE CRT was well accepted by outpatient veterans with SUDs and led to significant improvements in WM and executive functions beyond that of normal cognitive recovery. No difference between conditions was found for SUD outcomes, perhaps because work therapy obscured the benefits of CRT. (PsycINFO Database Record

Abstract
BACKGROUND Increasing evidence suggests that levels of pro-inflammatory and anti-inflammatory cytokines are dysfunctional in alcohol dependence. Moreover, some initial findings demonstrate that these adaptations in peripheral inflammation may contribute to motivation for alcohol and problem drinking via possible direct effects or the indirect effects of stress responsivity. Importantly, the role of pro-inflammatory and anti-inflammatory cytokines in the progression from healthy to problem drinking is not well understood. The aim of this study was to assess whether alcohol-related peripheral immune system changes affect stress and alcohol cue-induced craving and anxiety and behavioral alcohol motivation and intake in the laboratory among problem drinkers compared with socially drinking controls. METHODS Twenty-six problem drinkers and 38 moderate, social drinkers participated in a laboratory challenge procedure during which they were exposed to 3 personalized 5-minute imagery conditions (stress [S], relaxing [R], and alcohol cue [C]), followed by the "alcohol taste test" (ATT) as a measure of implicit alcohol motivation and intake, presented across 3 consecutive days, 1 per day in a randomized and counterbalanced order. Measures of tumor necrosis factor-alpha (TNFα), interleukin-6 (IL-6), interleukin-1 receptor antagonist (IL-1ra), alcohol craving, and anxiety were assessed at baseline, immediately following imagery exposure and at discreet beer cue presentation in the ATT. RESULTS Compared with moderate drinkers, problem drinkers demonstrated tonic attenuation of IL-6 and IL-1ra. In problem drinkers, these changes also accompanied elevated levels of stress- and cue-induced alcohol craving and anxiety and were predictive of provoked alcohol craving, behavioral alcohol motivation and intake, and severity of problem drinking. CONCLUSIONS Current findings indicate that selective immunosuppression in problem drinkers may play a key role in motivation for alcohol intake.

Abstract
This systematic review aims to examine growing evidence linking cognitive-executive functions with addiction treatment outcomes, and to discuss significant cognitive predictors drawing upon addiction neuroscience theory. We conducted a systematic search to identify studies using measures of general cognition and executive functions in patients with substance use disorders for the purpose of predicting two treatment outcomes: therapeutic adherence and relapse. Forty-six studies were selected, and sample characteristics, timing of assessments, and cognitive measures were analyzed. We observed significant methodological differences across studies, resulting in substantial variability in the relationships between cognitive-executive domains and treatment outcomes. Notwithstanding this variability, we found evidence of associations, of medium effect size, between general cognition and treatment adherence, and between reward-based decision-making and relapse. The link between general cognition and treatment adherence is consistent with emerging evidence linking limited cognitive-executive resources with less ability to benefit from talk therapies. The link between reward-based decision-making and relapse accords with decision neuroscience models of addiction. Findings may inform preclinical and clinical research concerning addiction treatment mechanisms.

Abstract
BACKGROUND Many adolescents in need of substance use disorder treatments never engage in treatment. Further, the most promising interventions that could be adapted to target treatment engagement often use normative feedback (NF) despite concerns about its appropriateness for adolescents. This preliminary study will inform a larger trial designed to isolate whether NF is an inert, helpful, or harmful active ingredient within pretreatment motivational interviewing (MI) interventions designed to increase treatment engagement. METHODS Adolescents (N = 48) presenting for treatment intake assessments were randomized to receive MI (n = 22) or MI+NF (n = 26) immediately following their assessments. Three-month outcomes included the percentage of youth engaged in treatment, the percentage of youth reporting past-month binge drinking, and the percentage of days of abstinence. RESULTS Treatments were delivered with high fidelity, and a high proportion of eligible participants were recruited and retained in this study. Participants significantly increased their percentage of days of abstinence by approximately 10% at follow-up (d = .32, P =.03), with no significant differences between groups. Fifty-five percent of youth in MI and 41.7% of youth in MI+NF engaged in treatment (odds ratio [OR] = .60, nonsignificant; 95% confidence interval, CI [0.136-2.68]). CONCLUSIONS Larger trials should test whether NF is an active ingredient in adolescent MI interventions, and should also determine the mechanisms through which MI+NF may produce effects.

Abstract
AIM Impaired illness insight may hamper treatment outcome in patients with alcohol-related cognitive deficits. In this study, a short questionnaire for the assessment of illness insight (eg, the Q8) was investigated in patients with Korsakoff's syndrome (KS) and in alcohol use disorder (AUD) patients with mild neurocognitive deficits. METHODS First, reliability coefficients were computed and internal structure was investigated. Then, comparisons were made between patients with KS and patients with AUD. Furthermore, correlations with the Dysexecutive Questionnaire (DEX) were investigated. Finally, Q8 total scores were correlated with neuropsychological tests for processing speed, memory, and executive function. RESULTS Internal consistency of the Q8 was acceptable (ie, Cronbach's α =0.73). The Q8 items represent one factor, and scores differ significantly between AUD and KS patients. The Q8 total score, related to the DEX discrepancy score and scores on neuropsychological tests as was hypothesized, indicates that a higher degree of illness insight is associated with a higher level of cognitive functioning. CONCLUSION The Q8 is a short, valid, and easy-to-administer questionnaire to reliably assess illness insight in patients with moderate-to-severe alcohol-related cognitive dysfunction.

Abstract
As older adults are prone to cognitive disorders, the interaction of the fields of substance use and misuse and cognitive neuroscience is an emerging area of research. Substance use has been reported in some subtypes of frontotemporal dementia, such as behavioral variant frontotemporal dementia. However, characterization of substance use in other subtypes of frontotemporal dementia, such as primary progressive aphasia, is unknown. The objective of this baseline analysis was to explore whether any measures of substance use history differed significantly among behavioral variant frontotemporal dementia (n = 842) and primary progressive aphasia (n = 526) in a large national dataset. The National Alzheimer's Coordinating Center's Uniform Data Set study is a national dataset that collects data on patients with various cognitive disorders and includes some questions on substance use. Each substance use variable was used as the outcome and the frontotemporal dementia subtype as the predictor. Total years smoked cigarettes, age when last smoked cigarettes, average number of packs/day smoked when participants smoked, and any recent, remote, or combined recent/remote history of alcohol abuse or drug abuse did not significantly differ between the behavioral variant frontotemporal dementia and primary progressive aphasia subtypes (all p-values > .001). A significantly greater percentage of participants smoked in the last 30 days in the behavioral variant frontotemporal dementia subtype (10.4%, n = 834) compared to the primary progressive aphasia subtype (3.3%, n = 517; p < .001). Clinical providers in both the dementia and substance use fields are encouraged to screen for and monitor substance use in all frontotemporal dementia subtypes.

Hotham S, Sharma D. The relationship between top-down attentional control and changes in weight. Eat Behav 2015; 18:81-3.

Abstract
AIM To investigate the relationship between top-down attentional control in the presence of food cues and weight change over a 3-month period. METHOD A Stroop task adapted to include background images of high-fat food and neutral items was completed by participants (N=60). Top-down attentional control was assessed by adaptation effects (Stroop effect is smaller when the previous trial is incongruent). To assess weight change, measurements were taken immediately after the Stroop task (T1) and again 3-months later (T2). Differences in weight between T1 and T2 were calculated and three groups formed: weight gain (n=20); weight loss (n=20); and no change in weight (n=20). RESULTS Differences in top-down attentional control were observed according to weight change. Participants who demonstrated reduced top-down attentional control also exhibited changes in weight (both loss and gain) over the 3-months. In contrast, the weight of participants who maintained top-down attentional control in the Stroop task remained stable. CONCLUSIONS Findings suggest that attentional control may have a role to play in actual eating behavior. Individuals who demonstrated reduced levels across of top-down attentional control also experienced changes in their weight over the 3-month period. Whether individuals lost or gained weight attentional control was reduced. This reduction was, however, not specific to high-fat food cues, but a general reduction in attentional control across both image conditions.

Abstract
We conducted a psychotherapeutic examination of the use of definitive drug testing (liquid chromatography with tandem mass spectrometry) in the treatment of substance use disorders (SUD). Employing a generic qualitative method (Caelli et al. in International Journal of Qualitative Methods, 2(2), 2003; Merriam, 2009) we asked SUD counselors to provide narratives about cases where drug testing had revealed new or unexpected information about clients’ drug-taking behaviors. Semi-structured interviews with 12 SUD counselors were conducted by phone and analyzed for themes derived from the literature. These counselors reported many new positive drug tests in clients previously believed to be adherent with treatment. Key themes assessed in counselors’ narratives included initial client denial that was often followed by later acknowledgement of relapse and increased motivation, at times presenting new opportunities for clients to engage in treatment and enhance the therapeutic alliance. These results suggest that definitive drug testing can be used in a non-stigmatizing and therapeutic manner.

Distinct facets of impulsivity exhibit differential associations with substance use disorder treatment processes: a cross-sectional and prospective investigation among military veterans. J Subst Abuse Treat 2015; 55:21-8.

Abstract
Impulsivity, a multi-faceted construct characterized by rash, unplanned actions and a disregard for long-term consequences, is associated with poor substance use disorder (SUD) treatment outcomes. Little is known though about the influence of impulsivity on treatment process variables critical for initiating and maintaining behavioral change. This knowledge gap is important as different aspects of impulsivity may be susceptible to diverse cognitive, behavioral and pharmacological influences. The present study examined two distinct facets of impulsivity (lack of planning and immoderation--a proxy of urgency) as predictors of processes that impact SUD treatment success (active coping, avoidant coping, self-efficacy, and interpersonal problems). Participants were 200 Veterans who completed impulsivity and treatment process assessments upon entering an SUD treatment program and treatment process assessments at treatment discharge. Results from multivariate models revealed that lack of planning was associated with lower active coping and higher avoidant coping and interpersonal problems at intake, though not with lower self-efficacy to abstain from substances. Immoderation was associated with higher avoidant coping and lower self-efficacy to abstain from substances at intake, but not with lower active coping or higher interpersonal problems. Higher immoderation, but not lack of planning, predicted lower self-efficacy to abstain from substances at treatment discharge. These findings suggest that different facets of impulsivity confer risk for different SUD treatment process indicators and that clinicians should consider the behavioral expression of patients' impulse control problems in treatment planning and delivery.

Abstract
OBJECTIVES Attenuation of adrenergic drive and cognitive enhancement, via stimulation of alpha2 pre- and post-synaptic receptors, may selectively enhance executive performance in early abstinent cocaine-dependent individuals. As these cognitive processes underpin important treatment-related behaviors, the alpha2 agonist, guanfacine HCl, may represent an effective pharmaco-therapeutic intervention. METHODS Twenty-five early abstinent cocaine-dependent individuals were administered a battery of neurocognitive tasks on entry into treatment (baseline) and again following 3 weeks of either placebo or guanfacine treatment (up to 3 mg). Tasks included: Stop Signal, Stroop, 3-Dimentional Intra-dimensional/Extra-dimensional (IDED) task, Spatial Working Memory (SWM), Paired Associates Learning (PAL), Verbal Fluency and the Rey Auditory Verbal Learning Test (RAVLT). RESULTS Compared with placebo, the guanfacine group demonstrated attenuated anxiety and negative affect as well as improved performance on selective executive tests. This included fewer directional errors on the stop signal task, fewer errors on the extra-dimensional shift component of the IDED task and better attentional switching during verbal fluency. Guanfacine did not improve strategic working memory or peripheral memory. CONCLUSION Guanfacine improves selective cognitive processes which may underlie salient treatment-related regulatory behaviors. Alpha2 agonists may therefore represent important agents for cocaine dependence.

Abstract
Childhood socioeconomic status (SES) predicts executive function (EF), but fundamental aspects of this relation remain unknown: the developmental course of the SES disparity, its continued sensitivity to SES changes during that course, and the features of childhood experience responsible for the SES-EF relation. Regarding course, early disparities would be expected to grow during development if caused by accumulating stressors at a given constant level of SES. Alternatively, they would narrow if schooling partly compensates for the effects of earlier deprivation, allowing lower-SES children to 'catch up'. The potential for later childhood SES change to affect EF is also unknown. Regarding mediating factors, previous analyses produced mixed answers, possibly due to correlation amongst candidate mediators. We address these issues with measures of SES, working memory and planning, along with multiple candidate mediators, from the NICHD Study of Early Childcare (n = 1009). Early family income-to-needs and maternal education predicted planning by first grade, and income-to-needs predicted working memory performance at 54 months. Effects of early SES remained consistent through middle childhood, indicating that the relation between early indicators of SES and EF emerges in childhood and persists without narrowing or widening across early and middle childhood. Changes in family income-to-needs were associated with significant changes in planning and trend-level changes in working memory. Mediation analyses supported the role of early childhood home characteristics in explaining the association between SES and EF, while early childhood maternal sensitivity was specifically implicated in the association between maternal education and planning. Early emerging and persistent SES-related differences in EF, partially explained by characteristics of the home and family environment, are thus a potential source of socioeconomic disparities in achievement and health across development.

Abstract
We propose that executive dysfunction is an important component relating to the socio-economic status gradient of select health behaviors. We review and find evidence supporting an SES gradient associated with (1) negative health behaviors (e.g., obesity, excessive use of alcohol, tobacco and other substances), and (2) executive dysfunction. Moreover, the evidence supports that stress and insufficient cognitive resources contribute to executive dysfunction and that executive dysfunction is evident among individuals who smoke cigarettes, are obese, abuse alcohol, and use illicit drugs. Collectively these data support the dual system model of cognitive control, referred to here as the Competing Neurobehavioral Decision Systems hypothesis. The implications of these relationships for intervention and social justice considerations are discussed.

Abstract
OBJECTIVE As sex differences in substance dependence may impinge upon the perception and regulation of emotion, we assess emotional intelligence (EI) as a function of gender, menstrual cycle (MC) phase and hormonal changes in early abstinent cocaine-dependent individuals who abuse alcohol (CDA). METHODS Study 1: The Mayer, Salovey, and Caruso Emotional Intelligence Test (MSCEIT) was administered to 98 CDA (55 M/43 F) and 56 healthy (28 M/28 F) individuals. Performance in women was also assessed by MC phase. Study 2: The MSCEIT was administered to 28 CDA (19 M/9 F) who received exogenous progesterone (400 mg/day) versus placebo for 7 days (study 2). RESULTS Study 1: Healthy females were better than healthy males at facilitating thought and managing emotions. This gender discrepancy was not observed in the CDA group. Additionally, all women in the high compared with the low progesterone phase of their MC were better at managing their emotions. Study 2: Exogenous progesterone improved ability to facilitate thought in both males and females. CONCLUSIONS CDA women may be vulnerable to difficulties managing and regulating emotions. Gonadal hormones may contribute to this gender effect, as increases in both endogenous and exogenous progesterone improved selective aspects of EI.

Abstract
The pathophysiology of cocaine addiction is linked to changes within neural systems and brain regions that are critical mediators of stress system sensitivity and behavioral processes associated with the regulation of adaptive goal-directed behavior. This is characterized by the upregulation of core adrenergic and corticotropin-releasing factor mechanisms that subserve negative affect and anxiety and impinge upon intracellular pathways in the prefrontal cortex underlying cognitive regulation of stress and negative emotional state. Not only are these mechanisms essential to the severity of cocaine withdrawal symptoms, and hence the trajectory of clinical outcome, but also they may be particularly pertinent to the demography of cocaine dependence. The ability of guanfacine to target overlapping stress, reward, and anxiety pathophysiology suggests that it may be a useful agent for attenuating the stress- and cue-induced craving state not only in women but also in men. This is supported by recent research findings from our own laboratory. Additionally, the ability of guanfacine to improve regulatory mechanisms that are key to exerting cognitive and emotional control over drug-seeking behavior also suggests that guanfacine may be an effective medication for reducing craving and relapse vulnerability in many drugs of abuse. As cocaine-dependent individuals are typically polydrug abusers and women may be at a greater disadvantage for compulsive drug use than men, it is plausible that medications that target catecholaminergic frontostriatal inhibitory circuits and simultaneously reduce stress system arousal may provide added benefits for attenuating cocaine dependence.

Abstract
BACKGROUND Deficits in several aspects of executive cognitive functioning (ECF) have been consistently associated with alcohol use disorders. Most of this research, however, has been conducted in alcohol dependent patient samples. A handful of recent studies, primarily in college students, have also reported similar deficits, but little is known about the effects of heavy drinking in adult, non-patient men and women. METHODS A community sample (N = 560) of men and women completed a brief battery of ECF measures including measures of attentional control, cognitive flexibility, working memory and response inhibition.Quantity/frequency of alcohol and illicit drug use in the past year were also assessed. RESULTS Regression analyses indicated that men and women with higher levels of alcohol consumption exhibited greater impairment on several ECF measures, primarily those pertaining to cognitive flexibility and response inhibition. These results remained after controlling for demographic factors such as age, gender, education, and illicit drug use. CONCLUSIONS These findings support and extend prior work documenting the deleterious effects of heavy alcohol consumption on ECF in a community sample and specifically indicate robust effects on cognitive flexibility,psychomotor speed, and response inhibition.

Abstract
Addiction treatment is a long-term goal and therefore prefrontal-striatal regions regulating goal-directed behavior are to be associated with individual differences on treatment motivation. We aimed at examining the association between gray matter volumes in prefrontal cortices and striatum and readiness to change at treatment onset in cocaine users with and without personality disorders. Participants included 17 cocaine users without psychiatric comorbidities, 17 cocaine users with Cluster B disorders, and 12 cocaine users with Cluster C disorders. They completed the University of Rhode Island Change Assessment Scale, which measures four stages of treatment change (precontemplation, contemplation, action, and maintenance) and overall readiness to change, and were scanned in a 3 T MRI scanner. We defined three regions of interest (ROIs): the ventromedial prefrontal cortex (including medial orbitofrontal cortex and subgenual and rostral anterior cingulate cortex), the dorsomedial prefrontal cortex (i.e., superior medial frontal cortex), and the neostriatum (caudate and putamen). We found that readiness to change correlated with different aspects of ventromedial prefrontal gray matter as a function of diagnosis. In cocaine users with Cluster C comorbidities, readiness to change positively correlated with gyrus rectus gray matter, whereas in cocaine users without comorbidities it negatively correlated with rostral anterior cingulate cortex gray matter. Moreover, maintenance scores positively correlated with dorsomedial prefrontal gray matter in cocaine users with Cluster C comorbidities, but negatively correlated with this region in cocaine users with Cluster B and cocaine users without comorbidities. Maintenance scores also negatively correlated with dorsal striatum gray matter in cocaine users with Cluster C comorbidities. We conclude that the link between prefrontal-striatal gray matter and treatment motivation is modulated by co-existence of personality disorders.
