Research focus

This article may help explain addiction science through research on opioid, withdrawal, craving, relapse. The source abstract begins by describing: “Existing pharmacological treatment options for opioid use disorder (OUD) face challenges that limit their efficacy.”

Key finding: This review adopts a translational approach to achieve several aims: (1) to outline the fundamental theories of orexin system function and relate orexinergic dysfunction to the disordered motivation and withdrawal states that characterize OUD; (2) to provide an up-to-date evaluation of preclinical and clinical evidence bases supporting the efficacy of orexin receptor antagonism for the treatment of OUD; (3) to discuss key clinical considerations of repurposing DORAs for OUD treatment, including safety and side effects (i.e., respiratory depression, anhedonia, and risk for abuse); and (4) to highlight the ongoing clinical efforts to determine therapeutic efficacy and safety profiles of DORAs for use in OUD populations.

Why this may help: This may help explain why addiction can involve brain, behavior, mental health, craving, relapse, or treatment factors rather than simple willpower alone. It should be read as research information, not personal medical advice.

PET imaging of FAAH in chronic Cannabis users: longitudinal assessment during short-term abstinence

This article may help explain addiction science through research on cannabis, brain science, withdrawal, craving. The source abstract begins by describing: “Cannabis withdrawal in cannabis use disorder (CUD) increase the risk of relapse and lacks effective treatments.”

Key finding: Increases in FAAH (%ΔFAAH whole-brain) were significantly associated with longer cannabis abstinence, greater baseline depression severity, and tendency to act without thinking ( p

Model of negative affect induced by withdrawal from acute and chronic morphine administration in male mice

This article may help explain addiction science through research on opioid, brain science, withdrawal, relapse. The source abstract begins by describing: “Opioid use disorder (OUD) is a chronic relapsing disorder that is a major burden for the lives of affected individuals, and society as a whole.”

Key finding: Altogether, these animal models will contribute to study behavioural and neuronal circuitries involved in the several negative affective signs characterizing OUD.

Cannabidiol mitigates alcohol dependence and withdrawal with neuroprotective effects in the basolateral amygdala and striatum

This article may help explain addiction science through research on alcohol, cannabis, brain science, withdrawal. The source abstract begins by describing: “Alcohol use disorder (AUD) remains a pervasive public health issue with limited effective treatments.”

Key finding: These findings indicate that chronic CBD administration attenuates both behavioral and neurobiological facets of alcohol dependence by modulating neuronal excitability and preventing neurodegeneration, supporting its therapeutic potential for AUD and providing mechanistic insights for future research.

Acetazolamide inhibition of carbonic anhydrase 4 reverses opioid-induced synaptic rearrangements in nucleus accumbens and reduces drug-seeking behavior

This article may help explain addiction science through research on opioid, cocaine, brain science, withdrawal. The source abstract begins by describing: “Persistent vulnerability to drug-seeking is driven by enduring synaptic adaptations, yet current μ-opioid receptor-targeting pharmacotherapies provide limited efficacy against these neuroadaptations.”

Key finding: By targeting a pathway independent of classical opioid receptor signaling, CA4 inhibition represents a mechanistically distinct strategy that may reduce relapse vulnerability in OUD.

Insular cortex subregions have distinct roles in cued heroin seeking after extinction learning and prolonged withdrawal in rats

This article may help explain addiction science through research on opioid, cocaine, brain science, withdrawal. The source abstract begins by describing: “Evidence indicates that the anterior (aIC), but not posterior (pIC), insular cortex promotes cued reinstatement of cocaine seeking after extinction in rats.”

Key finding: Moreover, the incubation of craving results suggest that new contingency learning is necessary to recruit the aIC in cued heroin seeking.
