BACKGROUND: The strong craving to smoke is a core factor of smoking abstinence that precipitates relapse. Insula plays critical roles in maintaining nicotine dependence, especially in the interoceptive awareness of craving. Despite evidence indicating a link between insula and abstinence-induced craving, less is known about the neural basis of abstinence-induced craving from the circuit level of insula. METHODS: The present study examined the effects of 12h of abstinence from smoking on the resting state functional connectivity (RSFC) of anterior (AI) and posterior insula in young smokers using a within-subject design...

INTRODUCTION: Nalmefene is the first drug to be approved for reducing alcohol consumption in alcohol use disorder (AUD) patients at high drinking risk. In real-world settings, there is a high prevalence of concurrent psychiatric disorders in AUD subjects, with associated increased morbidity and worse prognosis. This study evaluated the use of nalmefene in AUD patients with stabilized psychiatric comorbidity previously treated unsuccessfully for alcohol dependence, and assessed craving reduction and safety...

OBJECTIVE: Alcohol causes damage to the brain and is associated with various functional impairments. However, much of the brain damage can be reversed by abstaining for enough time. This study aims to investigate the patterns and degrees of brain function in abstinent patients with alcohol dependence by using resting-state functional connectivity. METHODS: 26 male patients with alcohol dependence (alcohol group) and 28 age-matched male healthy volunteers (control group) were recruited from a mental hospital and the community, respectively...

Dysfunctional eating behavior is a major risk factor for developing all sorts of eating disorders. Food craving is a concept that may help to understand better why and how these and other eating disorders become chronic conditions through non homeastatically-driven mechanisms. As obesity affects people worldwide, cultural differences must be acknowledged to apply proper therapeutic strategies. In this work, we adapted the Food Craving Inventory (FCI) to the German population. We performed a factor analysis of an adaptation of the original FCI in a sample of 326 men and women...

The infralimbic cortex (IL) mediates the extinction learning and active suppression of cocaine-seeking behavior. However, the precise temporal relationship among IL activity, lever pressing, and extinction learning is unclear. To address this issue, we employed activity-guided optogenetics in male Sprague-Dawley rats to optically silence IL pyramidal neurons for 20 s immediately following unreinforced lever presses during early extinction training after cocaine self-administration. Optical inhibition of the IL increased active lever pressing during shortened extinction sessions but did not alter the retention of the extinction learning as assessed in ensuing extinction sessions with no optical inhibition...

Seasonal pattern (SP) and metabolic syndrome (MetS) are major contributors to poor outcome in bipolar disorders (BD). Patients with seasonal bipolar depression present increased appetite, carbohydrate cravings, weight gain, and hypersomnia, which can increase the development of MetS. MetS also appears to be associated with seasonal mood changes in the general population. This study examines whether a SP in BD is associated with an increased risk of MetS and its sub-components. One thousand four hundred and seventy-one outpatients with BD were systematically enrolled from 2009 to 2016...

BACKGROUND: The automatic tendency to attend to and focus on substance-related cues in the environment (attentional bias), has been found to contribute to the persistence of addiction. Attentional bias modification (ABM) interventions might, therefore, contribute to treatment outcome and the reduction of relapse rates. Based on some promising research findings, we designed a study to test the clinical relevance of ABM as an add-on component of regular intervention for alcohol and cannabis patients...

According to the ambivalence model of craving, alcohol craving involves the dynamic interplay of separate approach and avoidance inclinations. Cue-elicited increases in approach inclinations are posited to be more likely to result in alcohol consumption and risky drinking behaviors only if unimpeded by restraint inclinations. Current study aims were (1) to test if changes in the net balance between approach and avoidance inclinations following alcohol cue exposure differentiate between low and high risk drinkers, and (2) if this balance is associated with alcohol consumption on a subsequent taste test...

Resting state functional brain connectivity (rsFC) may be an important neuromarker of smoking behavior. Prior research has shown, among cigarette smokers, that nicotine administration alters rsFC within frontal and parietal cortices involved in executive control, as well as striatal regions that drive reward processing. These changes in rsFC have been associated with reductions in withdrawal symptom severity. We currently have a limited understanding of how rsFC is affected by the use of electronic cigarettes (ecigs), an increasingly popular class of products, the members of which deliver nicotine with varying effectiveness...

Alcohol consumption is a major risk factor for the acquisition of HIV/AIDS and is associated with greater disease burden and mortality among those who become HIV-infected. Of the extant pharmacological treatments for alcohol use disorders, naltrexone is recognized as one of the most efficacious, producing robust reductions in alcohol craving and use. Given that treatment with oral naltrexone has been limited by problems with adherence, which are particularly prevalent among individuals with multiple chronic, co-occurring conditions, long-acting formulations may be a promising approach for HIV-infected substance users...

BACKGROUND & AIMS: Homocysteine is a sulfur amino acid strictly related with alcohol consumption. In alcoholics, hyperhomocysteinemia can increase the risk of various alcohol-related disorders such as: brain atrophy, epileptic seizures during withdrawal, and mood disorders. OBJECTIVE: To evaluate the correlation among serum homocysteine concentrations, craving, hazardous and harmful patterns of alcohol consumption in patients stabilized for withdrawal symptoms. METHODS: Participants were adult outpatients accessed at the Addiction Treatment Unit...

Aims: Alcohol dependence is a major public health issue with a need for new pharmacological treatments. The ALPADIR study assessed the efficacy and safety of baclofen at the target dose of 180 mg/day for the maintenance of abstinence and the reduction in alcohol consumption in alcohol-dependent patients. Methods: Three hundred and twenty adult patients (158 baclofen and 162 placebo) were randomized after alcohol detoxification. After a 7-week titration, the maintenance dose was provided for 17 weeks, then progressively decreased over 2 weeks before stopping...

BACKGROUND: Treatment using aversive conditioning has been suggested for smoking cessation. The efficacy of this method is thought to be associated with cognitive avoidance. We compare differences in avoidance traits and patterns of associated brain activation in response to cues that induce cravings versus aversion between smokers and non-smokers. METHODS: Fifteen smokers and fifteen non-smokers completed cue reactivity tasks while undergoing functional magnetic resonance imaging (fMRI) to examine brain responses to craving-inducing cues (Cr) and aversion-inducing cues (Av)...

Traumatic brain injury (TBI) can lead to changes in eating behavior patterns. This report describes the case of a patient with alcohol dependence presenting with behavioral changes and eating disorder following frontal lobe trauma. A 42-year-old male, premorbidly well-adjusted presented with alcohol use in dependent pattern for years. He sustained a subdural hematoma in the frontal lobe following a road traffic accident 10 years back. Post-TBI, the patient, started having low frustration tolerance, aggressive outbursts, disinhibition, difficulty in persisting with tasks, apathy, amotivation, and craving for food with inability to control intake on the sight of food...

Appetitive Pavlovian conditioning plays a crucial role in the pathogenesis of drug addiction and conditioned reward cues can trigger craving and relapse even after long phases of abstinence. Promising preclinical work showed that the NMDA-receptor partial agonist D-cycloserine (DCS) facilitates Pavlovian extinction learning of fear and drug cues. Furthermore, DCS-augmented exposure therapy seems to be beneficial in various anxiety disorders, while the supposed working mechanism of DCS during human appetitive or aversive extinction learning is still not confirmed...

Introduction: Aerobic exercise may improve smoking abstinence via reductions in craving and negative affect, and increases in positive moods. Acute changes in craving and affect before and after structured exercise sessions have not been examined during the weeks prior to and following quit attempts, nor has smoking status been examined in relation to these effects. Given that regular cigarette smoking can be perceived as affect-enhancing and craving-reducing, it is not known whether exercise could contribute additional affective benefit beyond these effects...

Eric Racine, Simon Rousseau-Lesage
The degree of autonomy present in the choices made by individuals with an addiction, notably in the context of research, is unclear and debated. Some have argued that addiction, as it is commonly understood, prevents people from having sufficient decision-making capacity or self-control to engage in choices involving substances to which they have an addiction. Others have criticized this position for being too radical and have counter-argued in favour of the full autonomy of people with an addiction. Aligning ourselves with middle-ground positions between these two extremes, we flesh out an account of voluntary action that makes room for finer-grained analyses than the proposed all-or-nothing stances, which rely on a rather static metaphysical understanding of the nature of the voluntariness of action...
