Background Problematic Internet use (PIU) is an emerging entity with varied contents. Behavioral addictions have high comorbidity of attention deficit hyperactivity disorder and obsessive-compulsive spectrum disorders. Social networking site (SNS) addiction and role playing game (RPG) addiction are traditionally studied as separate entities. We present a case with excessive Internet use, with a...

Context: In animals, repeated exposure to stimulant drugs leads to an enhanced drug-induced psychomotor response and increased dopamine release. This phenomenon, known as sensitization, may confer vulnerability to drug addiction or drug-induced psychosis in humans. A similar phenomenon, referred to as endogenous sensitization, is also believed to play a role in the emergence of positive symptom...

Genetic factors are considered to play an important role in drug dependence/addiction including the development of drug dependence and relapse. With the use of a model of drug self-administration in mutant mice, several specific genes and proteins have been identified as potentially important in the development of drug dependence. In contrast, little is known about the role of specific genes in...

Drugs of abuse dynamically regulate adult neurogenesis, which appears important for some types of learning and memory. Interestingly, a major site of adult neurogenesis, the hippocampus, is important in the formation of drug-context associations and in the mediation of drug-taking and drug-seeking behaviors in animal models of addiction. Correlative evidence suggests an inverse relationship bet...

As new media are becoming daily fare, Internet addiction appears as a potential problem in adolescents. From the reported negative consequences, it appears that Internet addiction can have a variety of detrimental outcomes for young people that may require professional intervention. Researchers have now identified a number of activities and personality traits associated with Internet addiction....

This study examined smokers’ reactions to antismoking messages that emphasized either the harms of secondhand smoke or vulnerability to smoking addiction and framed the need for smoking cessation using either gain or loss message frames. One hundred fifty-four college smokers participated in a study that used a 2 x 2 factorial design crossing message type (secondhand smoke appeals, smoking addi...

With its medicalization as a brain-based disease, addiction has come to be regarded as amenable to biomedical treatment approaches, most commonly pharmacotherapy. Various vulnerabilities are recognized to contribute to maladaptive substance use, and have been linked to diverse neurobiological alterations that may be targeted with pharmacotherapy: withdrawal, craving and cue reactivity, and aber...

Dopaminergic signals play a mathematically precise role in reward-related learning, and variations in dopaminergic signaling have been implicated in vulnerability to addiction. Here, we provide a detailed overview of the relationship between theoretical, mathematical, and experimental accounts of phasic dopamine signaling, with implications for the role of learning-related dopamine signaling in...

a b s t r a c t “addiction” is a multifaceted complicated disorder with many interrelated causes, as well as environmental and genetic features. several hereditary variables that have an effect on these features might work in together to influence vulnerability and the extent of being an addict. molecular re-sequencing of the latest and formerly researched genes holds a crucial place with regar...
