Recent progress in the genomics and epigenomics of addiction has contributed to improving our understanding this complex mental disorder's etiology, filling gap between genes, environment, behavior. We review behavioral genetic studies reporting gene environment interactions that explain polygenetic contribution resilience vulnerability develop addiction. discuss evidence polymorphic candidate ...
In humans, adolescence is a period of heightened propensity to develop cocaine addiction. It is unknown whether this is attributable to greater access and exposure to cocaine at this age, or whether the adolescent brain is particularly vulnerable to the addictive properties of cocaine. Here, we subjected male adolescent (P42) and adult (∼P88) rats to a wide range of cocaine self-administration ...
Autism Spectrum Disorders and Drug Addiction: Common Pathways, Common Molecules, Distinct Disorders?
Autism spectrum disorders (ASDs) and drug addiction do not share substantial comorbidity or obvious similarities in etiology or symptomatology. It is thus surprising that a number of recent studies implicate overlapping neural circuits and molecular signaling pathways in both disorders. The purpose of this review is to highlight this emerging intersection and consider implications for understan...
We present a hypothetical neurocomputational model that combines a set of neural circuits at the molecular, cellular, and system levels and accounts for several neurobiological and behavioral processes leading to nicotine addiction. We propose that combining changes in the nicotinic receptor response, expressed by mesolimbic dopaminergic neurons, with dopamine-gated learning in action-selection...
Conventional definitions of drug addiction are focused on characterizing the neurophysiological and behavioral responses of mammals. Although mammalian models have been invaluable in studying specific and complex aspects of addiction, invertebrate systems have proven advantageous in investigating how drugs of abuse corrupt the most basic motivational and neurochemical systems. It has recently b...
Paradigms used to study the response to and consequences of exposure to reward loss have been underutilized in approaches to the psychobiology of substance use disorders. We propose here that bringing these two areas into contact will help expanding our understanding of both reward loss and addictive behavior, hence opening up opportunities for cross-pollination. This review focuses on two line...
Chronic exposure to cocaine causes long-lasting behavioral changes associated with cocaine reinforcement and addiction. An important neural substrate for cocaine addiction is the nucleus accumbens (NAc), which receives dopaminergic input from the ventral tegmental area. Although the neural circuit of the NAc is controlled by several other neurotransmitters, their involvement in cocaine addictio...
Alcohol and drug abuse take a large toll on society and affected individuals. However, very few effective treatments are currently available to treat alcohol and drug addiction. Basic and clinical research has begun to provide some insights into the underlying neurobiological systems involved in the addiction process. Several neurotransmitter pathways have been implicated and distinct reward ne...
BACKGROUND AND AIMS Internet Gaming Disorder, a subtype of Internet Addiction, is now classified in Section 3 of the DSM-5. Cognitive behavioral therapy (CBT) has been suggested in treating Internet addiction as this modality has been shown to be an effective treatment for similar impulse control disorders. Given the daily and necessary use of the Internet and technology in general compared to ...
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...
