It is increasingly well accepted that addiction can be viewed as a form of neuronal plasticity, even as a type of very powerful, albeit maladaptive, learning. On a behavioral level, this can be conceptualized as the transition from experimentation to compulsive drug-seeking behavior. This view of addiction has been strengthened by many recent studies demonstrating commonalities between mechanis...

Background and Aim: Internet addiction means excessive and unnecessary use of the Internet. The aim of this study was to investigate the role of brain-behavioral systems in Internet addiction among university students. Materials and Methods: This was a descriptive and correlational research. The statistical population was all the students of Islamic Azad University, Karaj Branch in the academi...

The dramatically increasing prevalence of obesity, associated with potentially life-threatening health problems, including cardiovascular diseases and type II diabetes, poses an enormous public health problem. It has been proposed that the obesity epidemic can be explained by the concept of 'food addiction'. In this review we focus on possible similarities between binge eating disorder (BED), w...

Work-related addiction can be considered one of the “new behavioral addictions” as no addictive substance is taken by the individual. From the second half of the twentieth century onwards, researchers have focused their attention on various forms of behavioral addictions such as physical exercise, compulsive shopping, playing computer games, gambling, excessive internet use and even addiction t...

Scientific advances over the past 20 years have shown that drug addiction is a chronic, relapsing disease that results from the prolonged effects of drugs on the brain. As with many other brain diseases, addiction has embedded behavioral and social-context aspects that are important parts of the disorder itself. Therefore, the most effective treatment approaches will include biological, behavio...

Drug addiction is a complex neurological dysfunction induced by recurring drug intoxication. Strategies to prevent and treat drug addiction constitute a topic of research interest. Early-stage romantic love is characterized by some characteristics of addiction, which gradually disappear as the love relationship progresses. Therefore, comparison of the concordance and discordance between romanti...

BACKGROUND AND AIMS Recent studies have challenged the anxiety-avoidance model of obsessive-compulsive disorder (OCD), linking OCD to impulsivity, risky-decision-making and reward-system dysfunction, which can also be found in addiction and might support the conceptualization of OCD as a behavioral addiction. Here, we conducted an exploratory investigation of the behavioral addiction model of O...

Illicit psychostimulant addiction remains a significant problem worldwide, despite decades of research into the neural underpinnings and various treatment approaches. The purpose of this review is to provide a succinct overview of the neurocircuitry involved in drug addiction, as well as the acute and chronic effects of cocaine and amphetamines within this circuitry in humans. Investigational p...
