PURPOSE: Rising rates of obesity have been recently associated to the novel concept of food addiction (FA). The Yale Food Addiction Scale (YFAS) is the most widely used measure for examining FA (1) and analysis of its reliability and validity is expected to facilitate empirical research on the construct. Here, we tested the psychometric properties of a Portuguese version of the YFAS (P-YFAS), establishing its factor structure, reliability and construct validity. METHODS: Data were obtained from 468 Portuguese individuals, 278 sampled from non-clinical populations, and 190 among obese candidates for weight-loss surgery...

Dopamine is associated with a variety of conserved responses across species including locomotion, sleep, food consumption, aggression, courtship, addiction and several forms of appetitive and aversive memory. Historically, dopamine has been most prominently associated with dynamics underlying reward, punishment, or salience. Recent emerging evidence from Drosophila supports a role in all of these functions, as well as additional roles in the interplay between external sensation and internal states and forgetting of the very memories dopamine helped encode...

Based on similarities between overconsumption of food and addictive drugs, there is increasing interest in "food addiction," a compulsive eating pattern defined using symptoms parallel to substance use disorders. Impulsivity, a multidimensional construct robustly linked to drug addiction, has been increasingly examined as an obesity determinant, but with mixed findings. This study sought to clarify relations between three major domains of impulsivity (i.e., impulsive personality traits, discounting of delayed rewards, and behavioral inhibition) in both obesity and food addiction...

Tobacco companies in the United States are prohibited from making reduced harm claims without filing a modified risk tobacco product application with the Food and Drug Administration and obtaining an order to market as such. However, it is possible that product marketing may suggest reduced risk to individuals. This study examines perceptions, in particular those related to harm and addiction, of snus print advertisements using a combination of eye-tracking, survey, and semistructured interviews. Participants were 22 male smokers ages 19-29 (M = 26...

: Pain in sickle cell disease (SCD) is associated with increased morbidity, mortality, and high healthcare costs. While episodic acute pain is the hallmark of this disorder, there is an increasing awareness that chronic pain is part of the pain experience of many older adolescents and adults. A common set of criteria for classifying chronic pain associated with SCD would enhance SCD pain research efforts in epidemiology, pain mechanisms, and clinical trials of pain management interventions, and ultimately improve clinical assessment and management...

This review examines the merits of 'food addiction' as an explanation of excessive eating (i.e., eating in excess of what is required to maintain a healthy body weight). It describes various apparent similarities in appetites for foods and drugs. For example, conditioned environmental cues can arouse food and drug-seeking behaviour, 'craving' is an experience reported to precede eating and drug taking, 'bingeing' is associated with both eating and drug use, and conditioned and unconditioned tolerance occurs to food and drug ingestion...

Tetrahydroprotoberberines (THPB) have a high affinity for dopamine (DA) D1 and D2 receptors and may provide a novel treatment for drug addiction. We assessed the effects of the THPB d-govadine on the acquisition, expression, extinction and reinstatement of d-amphetamine-(1.5mg/kg, i.p.) induced conditioned place preference (CPP). Furthermore, the effects of d-govadine on conditioned association between contextual stimuli and a natural reward were examined using food-induced CPP. In separate experiments, rats received d-govadine (0, 0...

BACKGROUND: Health inequities are increasing worldwide, with mounting evidence showing that the greatest cause of which are social determinants of health. To reduce inequities, a lot of citizens need to be able to access, understand, appraise, and apply information on the social determinants; that is, they need to improve health literacy on social determinants of health. However, only a limited number of scales focus on these considerations; hence, we developed the Health Literacy on Social Determinants of Health Questionnaire (HL-SDHQ) and examined its psychometric properties...

Cue reactivity is an established procedure in addictions research for examining the subjective experience and neural basis of craving. This experiment sought to quantify cue-related brain responses in gambling disorder using personally tailored cues in conjunction with subjective craving, as well as a comparison with appetitive non-gambling stimuli. Participants with gambling disorder (n=19) attending treatment and 19 controls viewed personally tailored blocks of gambling-related cues, as well as neutral cues and highly appetitive (food) images during a functional magnetic resonance imaging (fMRI) scan performed ~2-3 h after a usual meal...

MicroRNAs (miRNAs) are important post-transcriptional regulators of gene expression and are implicated in the etiology of several neuropsychiatric disorders, including substance use disorders (SUDs). Using in silico genome-wide sequence analyses, we identified miR-495 as a miRNA whose predicted targets are significantly enriched in the Knowledgebase for Addiction Related Genes (ARG) database (KARG; http://karg.cbi.pku.edu.cn). This small non-coding RNA is also highly expressed within the nucleus accumbens (NAc), a pivotal brain region underlying reward and motivation...

Understanding individual differences in response to social stress and environmental enrichment on brain function and drug abuse may help explain the variability in response to behavioral and pharmacological treatments for drug addiction. In monkeys, social status influences the reinforcing effects of cocaine and the effects of some drugs on cocaine self-administration. In this study, we used male cynomolgus macaques (n=15) living in established social groups to examine the effects of social confrontation on the reinforcing effects of cocaine using a food-drug choice procedure...

Night eating syndrome (NES) is commonly assessed using the Night Eating Questionnaire (NEQ), a validated scale of symptom severity, which does not assess all diagnostic criteria. The Night Eating Diagnostic Questionnaire (NEDQ) assesses all diagnostic criteria, but has not been fully validated. The study purpose was to establish convergent validity for the NEDQ with the NEQ. It was also expected that higher NEDQ scores would be associated with elevated depression, poorer sleep quality, "food addiction," and BMI as in other studies of NES...

Ghrelin, which is mainly released from the stomach, is the most important orexigenic regulator of food intake, inducing appetite, enhancing adiposity and releasing growth hormone. Besides the hypothalamus, ghrelin receptors (GHS-R1A) are also expressed in the mesolimbic dopaminergic system, which increases the possibility that ghrelin plays an important role in reward regulation for substance use disorders such as alcohol addiction, especially through activating the cholinergic-dopaminergic reward link. In this review we focus on the impact of ghrelin on the development and maintenance of alcohol addiction/dependence, alcohol consumption, alcohol craving and alcohol withdrawal, attempting to integrate preclinical and clinical studies concerning the intriguing relationship between appetite regulation, reward and alcohol addiction...

The increasing worldwide prevalence of obesity is partially related to the ready availability of highly palatable foods which increases the incidence of hedonic, non-homeostatic feeding. The "food addiction" hypothesis postulates that exposure to these foods alters the brain's reward circuitry, driving an addiction-like behavioural phenotype of compulsive overeating. This review highlights recent evidence that examines changes in the mesolimbic dopaminergic circuit, the primary component of the reward system, associated with exposure to highly palatable foods and obesity...

Recent lines of experimental evidence have indicated that saikosaponin A (SSA) - a bioactive ingredient of the medicinal plant, Bupleurum falcatum L. - suppressed alcohol, morphine, and cocaine self-administration in rats. The present paper was designed to assess whether the protective properties of SSA on addiction-related behaviors generalize to a hyperpalatable food such as a chocolate-flavored beverage (CFB). To this end, rats were initially trained to lever-respond for CFB [5% (w/v) Nesquik(®) powder in water] under fixed ratio (FR) 10 (FR10) schedule of reinforcement...

It is well established that obesity has reached pandemic proportions. Over the last four decades the prevalence of obesity and morbid obesity have risen substantially in both men and women worldwide. Although there are many causative factors leading to excessive weight gain including genetics and sedentary lifestyle, the transformation of the food environment has undoubtedly contributed to the dangerously high rates of obesity. The current food landscape is inundated with food engineered to contain artificially high levels of sugar and fat...

The food addiction construct posits that vulnerable individuals may experience an addictive-like response to certain foods, such as those high in fat and refined carbohydrates. Recently, an alternative model to food addiction was proposed, suggesting that the act of eating may be a behavioral addiction that can trigger an addictive-like response in susceptible individuals. One major rationale for the eating addiction framework is that the assessment of food addiction is based on behavioral indicators, such as consuming greater quantities of food than intended and eating certain foods despite negative consequences...

: A novel G-protein coupled receptor, trace amine-associated receptor 1 (TAAR1), has been shown to be a promising target to prevent stimulant relapse. Our recent studies showed that systemic administration of TAAR1 agonists decreased abuse-related behaviors of cocaine. However, the role of TAAR1 in specific subregions of the reward system in drug addiction is unknown. Here, using a local pharmacological activation method, we assessed the role of TAAR1 within the subregions of the mesocorticolimbic system, i...
