Medical and genetic correlates of long-term buprenorphine treatment in the electronic health records

This article may help explain addiction science through research on opioid, alcohol, cannabis, nicotine. The source abstract begins by describing: “Despite the benefits associated with longer buprenorphine treatment duration (i.e., >180 days) (BTD) for opioid use disorder (OUD), retention remains poor.”

Key finding: Longer BTD is associated with diagnoses of psychiatric and somatic conditions in the EHR, as is the genetic score for OUD, loneliness, problematic alcohol use, and externalizing disorders.

Enduring disruption of reward and stress circuit activities by early-life adversity in male rats

This article may help explain addiction science through research on opioid, cocaine, brain science, mental health. The source abstract begins by describing: “In humans, early-life adversity (ELA) such as trauma, poverty, and chaotic environment is linked to increased risk of later-life emotional disorders including depression and substance abuse.”

Key finding: Our findings, taken together with our prior work, suggest that men and women could face qualitatively different mental health consequences of ELA, which may be essential for individually tailoring future intervention strategies.

Rates and correlates of cannabis-associated psychotic symptoms in over 230,000 people who use cannabis

This article may help explain addiction science through research on cannabis, nicotine, mental health, treatment. The source abstract begins by describing: “Cannabis, a widely used psychoactive substance, can trigger acute cannabis-associated psychotic symptoms (CAPS) in people who use cannabis (PWUC).”

Key finding: In light of the movements towards legalization of recreational cannabis, more research should focus on the potential harms related to cannabis use, to educate PWUC and the public about risks related to its use.

Accelerated development of cocaine-associated dopamine transients and cocaine use vulnerability following traumatic stress

This article may help explain addiction science through research on cocaine, dopamine, genetics, mental health. The source abstract begins by describing: “Post-traumatic stress disorder and cocaine use disorder are highly co-morbid psychiatric conditions.”

Key finding: Together, our studies demonstrate that susceptibility to traumatic stress is associated with a cocaine use-vulnerable phenotype and suggests that differences in phasic dopamine signaling architecture may contribute to the process by which this vulnerability occurs.

Where There is Smoke There is Fear—Impaired Contextual Inhibition of Conditioned Fear in Smokers

This article may help explain addiction science through research on nicotine, mental health. The source abstract begins by describing: “The odds-ratio of smoking is elevated in populations with neuropsychiatric diseases, in particular in the highly prevalent diagnoses of post-traumatic stress and anxiety disorders.”

Key finding: We propose that smokers have a deficit in integrating contextual signs of safety, which is a hallmark of post-traumatic stress and anxiety disorders.

Keep off the grass? Cannabis, cognition and addiction

This article may help explain addiction science through research on alcohol, cannabis, nicotine, mental health. The source abstract begins by describing: “Cannabis is used widely as a recreational drug, and its legalization is an ongoing issue in several countries.”

Key finding: Here, we review the current state of knowledge about such vulnerability factors, the variations in types of cannabis, and the relationship between these and cognition and addiction.

The effect and neural changes underlying mindfulness meditation training in patients with comorbid internet gaming disorder and depression: A randomized clinical trial

This article may help explain addiction science through research on dopamine, brain science, craving, genetics. The source abstract begins by describing: “Internet gaming disorder (IGD) has been recognized as a serious mental illness and is often accompanied by depression (IGD-D).”

Key finding: These phenomena were supported by the correlation between FC and behavioral as well as biochemical measures, suggesting that MM is a promising therapy for IGD-D.

Gambling disorder

This article may help explain addiction science through research on opioid, genetics, mental health, treatment. The source abstract begins by describing: “Gambling disorder is characterized by a persistent, recurrent pattern of gambling that is associated with substantial distress or impairment.”

Key finding: This Primer describes the epidemiology, neurobiology, diagnosis, screening, prevention and treatment of this behavioural disorder, and discusses the quality of life of individuals affected.

Adolescent alcohol exposure produces sex differences in negative affect-like behavior and group I mGluR BNST plasticity

This article may help explain addiction science through research on alcohol, withdrawal, relapse, mental health. The source abstract begins by describing: “Adolescent alcohol exposure increases the risk of developing alcohol use disorders (AUDs), yet the mechanisms responsible for this vulnerability remain largely unknown.”

Key finding: These studies demonstrate long-lasting, sex-dependent phenotypes produced by AIE and suggest pharmaceutical interventions for alcohol use and comorbid disorders may be more effective if designed with sex differences in mind.

NPY signaling inhibits extended amygdala CRF neurons to suppress binge alcohol drinking

This article may help explain addiction science through research on alcohol, brain science, genetics, mental health. The source abstract begins by describing: “The authors demonstrate that the anti-stress peptide neuropeptide Y reduces binge drinking in monkeys and mice by inhibiting neurons in the amygdala that contain the stress peptide corticotropin-releasing factor.”

Key finding: Together, these data provide both a cellular locus and signaling framework for the development of new therapeutics for treatment of neuropsychiatric diseases, including alcohol use disorders.

Dorsal raphe serotonin neurons inhibit operant responding for reward via inputs to the ventral tegmental area but not the nucleus accumbens: evidence from studies combining optogenetic stimulation and serotonin reuptake inhibition

This article may help explain addiction science through research on dopamine, brain science, genetics, mental health. The source abstract begins by describing: “The monoamine neurotransmitter serotonin (5-hydroxytryptamine; 5-HT) exerts an inhibitory influence over motivation, but the circuits mediating this are unknown.”

Key finding: These studies support an oppositional interaction between 5-HT and DA systems in controlling motivation and goal-directed behavior, and have important implications for the development and refinement of treatment strategies for psychiatric disorders such as depression and addiction.

Optogenetic investigation of neural circuits underlying brain disease in animal models

This article may help explain addiction science through research on brain science, genetics, mental health, review. The source abstract begins by describing: “Optogenetics enables the precise and targeted manipulation of the activity of specific neurons and is a powerful tool for the dissection of neural circuits.”

Key finding: The rapid proliferation of optogenetic reagents together with the swift advancement of strategies for implementation has created new opportunities for causal and precise dissection of the circuits underlying brain diseases in animal models.

Nucleus accumbens medium spiny neurons subtypes signal both reward and aversion

This article may help explain addiction science through research on opioid, cocaine, dopamine, brain science. The source abstract begins by describing: “Deficits in decoding rewarding (and aversive) signals are present in several neuropsychiatric conditions such as depression and addiction, emphasising the importance of studying the underlying neural circuits in detail.”

Key finding: Our findings demonstrate that D1- and D2-MSNs can bidirectionally control reward and aversion, explaining the existence of controversial studies in the field, and highlights that the proposed striatal functional opposition needs to be reconsidered.
