A disruption of the oxytocin system seems to affect a variety of brain functions including emotions, mood and social behavior possibly underlying severe social deficits and susceptibility for substance use and mental health disorders. Early life adversity, such as insecure attachment in childhood, has been suggested to influence oxytocin tone contributing to a condition of neurobiological vulnerability. Aim of the present study was to investigate oxytocin serum levels in abstinent heroin addicted patients, in comparison with healthy controls, and the possible correlation with co-occurring psychiatric symptoms, aggressiveness and perception of parental neglect...

BACKGROUND: Bipolar disorder (BD) may be characterized by the presence of psychotic symptoms and comorbid substance abuse. In this context, structural and metabolic dysfunctions have been reported in both BD with psychosis and addiction, separately. In this study, we aimed at identifying neural substrates differentiating psychotic BD, with or without substance abuse, versus substance-induced psychosis (SIP) by coupling, for the first time, magnetic resonance imaging (MRI) and positron emission tomography (PET)...

In the fifth edition of the Diagnostic and Statistical Manual for Mental Disorders (DSM-5), gambling disorder (GD) underwent several changes. This paper reviews recent research related to the revisions, including the elimination of the illegal acts criterion and the newly lowered diagnostic threshold. These studies suggest the removal of the illegal acts criterion has little impact in terms of prevalence or loss of diagnostic status among gamblers, especially when considered in combination with the newly lowered diagnostic threshold...

Nicotine is the primary pharmacologic component of tobacco, and users of tobacco products seek out its effects. The highly addictive nature of nicotine is responsible for its widespread use and difficulty with quitting. This technical report focuses on nicotine and discusses the stages of use in progression to dependence on nicotine-containing products; the physiologic characteristics, neurobiology, metabolism, pharmacogenetics, and health effects of nicotine; and acute nicotine toxicity. Finally, some newer approaches to cessation are noted...

We report the case of a 32-year-old man who developed acute psychiatric disorders after repeated intravenous injections of methylphenidate. The behavioural disorders with extreme psychomotor restlessness and delirious syndrome have resolved within 24hours. The available data highlight the fact that the prescriptions of methylphenidate, an amphetamine-like substance, are constantly increasing in Europe and Northern America. The potential of abuse and addiction to this drug, which is growingly misused, is now clearly established...

Cerebral blood flow ensures delivery of nutrients, such as glucose, to brain sites with increased metabolic demand. However, little is known about rapid glucose dynamics at discrete locations during neuronal activation in vivo. Acute exposure to many substances of abuse elicits dopamine release and neuronal activation in the striatum; however, the concomitant changes in striatal glucose remain largely unknown. Recent developments have combined fast-scan cyclic voltammetry with glucose oxidase enzyme modified carbon-fiber microelectrodes to enable the measurement of glucose dynamics with subsecond temporal resolution in the mammalian brain...

Recreational drug use leads to compulsive substance abuse in some individuals. Studies on animal models of drug addiction indicate that persistent long-term potentiation (LTP) of excitatory synaptic transmission onto ventral tegmental area (VTA) dopamine (DA) neurons is a critical component of sustained drug seeking. However, little is known about the mechanism regulating such long-lasting changes in synaptic strength. Previously, we identified that translational control by eIF2α phosphorylation (p-eIF2α) regulates cocaine-induced LTP in the VTA (Huang et al...

BACKGROUND: Onset of alcohol use by 14 relative to 21 years of age strongly predicts elevated risk for severe alcohol use problems, with 27% versus 4% of individuals exhibiting alcohol dependence within 10 years of onset. What remains unclear is whether this early alcohol use (i) is a marker for later problems, reflected as a pre-existing developmental predisposition, (ii) causes global neural atrophy or (iii) specifically disturbs neuro-maturational processes implicated in addiction, such as executive functions or reward processing...

This paper summarizes The American Journal of Drug and Alcohol Abuse special issue and offers suggestions for future steps. People who use alcohol or other addictive substances are much more likely to use tobacco. Yet, clinicians and scientists have long regarded these addiction categories as separate and unrelated. The resultant benign neglect of tobacco use has had disastrous consequences on patients. This special issue is an important step toward remedying that situation. It has reviewed what is known and what more needs to be discovered regarding the co-occurrence of tobacco use disorder (TUD) and other substance use disorders (SUDs)...

The regulatory mechanisms underlying the response to addictive drugs are complex, and increasing evidence indicates that there is a role for appetite-regulating pathways in substance abuse. Leptin, an important adipose hormone that regulates energy balance and appetite, exerts its physiological functions via leptin receptors. However, the role of leptin signaling in regulating the response to cocaine remains unclear. Here we examined the potential role of leptin signaling in cocaine reward using a conditioned place preference (CPP) procedure...

Shawn M Aarde, Michael A Taffe
Animal models of drug self-administration are currently the gold standard for making predictions regarding the relative likelihood that a recreational drug substance will lead to continued use and addiction. Such models have been found to have high predictive accuracy and discriminative validity for a number of drug classes including ethanol, nicotine, opioids, and psychostimulants such as cocaine and methamphetamine. Members of the entactogen class of psychostimulants (drugs that produce an "open mind state" including feelings of interpersonal closeness, intimacy and empathy) have been less frequently studied in self-administration models...

OBJECTIVE: To describe if there are differences in the prescription of psychodrug at discharge between bipolar disorder patients with or without addiction. METHODS: We review all the psychotropic drugs dispensed to inpatients of a brief hospitalization psychiatric unit diagnosed as having bipolar disorder at time of discharge. We recluted 225 patients over 18 years old on their last manic episode, between the year 2000 and 2010. We classify them according to the comorbid presence or not of a substance abuse or dependence disorder...

With the evolving sensitivity of positron emission tomography (PET) and the emergence of novel radiotracers, greater insight has been gained into the dopaminergic system as it relates to substance use. In this review, we summarize PET investigations from the last ten years that explore the dopaminergic system in tobacco, alcohol, stimulant, opiates, and cannabis addiction. In light of the prevalence of substance co-use, this review will also explore the effect of tobacco and other substance abuse co-morbidity on the dopaminergic system across study samples in the reviewed literature...
