Childhood adversity negatively influences all stages of the addiction process and is associated with persistent alterations in neuroendocrine, autonomic and brain responses to stress. We sought to characterize the impact of childhood abuse and neglect on the neural correlates of stress- and drug cue-induced drug craving associated with cocaine addiction. Cocaine-dependent men with (n = 20) and ...
We investigated brain circuitry mediating cocaine-induced euphoria and craving using functional MRI (fMRI). During double-blind cocaine (0.6 mg/kg) and saline infusions in cocaine-dependent subjects, the entire brain was imaged for 5 min before and 13 min after infusion while subjects rated scales for rush, high, low, and craving. Cocaine induced focal signal increases in nucleus accumbens/subc...
Cue-induced craving is not easily reduced by an extinction or exposure procedure and may constitute an important route toward relapse in addictive behavior after treatment. In the present study, we investigated the effectiveness of counterconditioning as an alternative procedure to reduce cue-induced craving, in a nonclinical population. We found that a cue, initially paired with chocolate cons...
Drug use and relapse involve learned associations between drug-associated environmental cues and drug effects. Extinction procedures in the clinic can suppress conditioned responses to drug cues, but the extinguished responses typically reemerge after exposure to the drug itself (reinstatement), the drug-associated environment (renewal), or the passage of time (spontaneous recovery). We describ...
Remission of Methamphetamine-Induced Withdrawal Delirium and Craving After Electroconvulsive Therapy
INTRODUCTION The aim of this study is to describe the use of electroconvulsive therapy (ECT) in the treatment of methamphetamine-induced withdrawal delirium and craving in a single case. CASE PRESENTATION A 44-year-old male presented to the hospital in Fars province, Iran, with Methamphetamine-Induced Withdrawal Delirium who responded to ECT. CONCLUSIONS The electroconvulsive therapy can be...
The ventral striatum/nucleus accumbens (NAcc) has been implicated in the craving for drugs and alcohol which is a major reason for relapse of addicted people. Craving might be induced by drug-related cues. This suggests that disruption of craving-related neural activity in the NAcc may significantly reduce craving in alcohol-dependent patients. Here we report on preliminary clinical and neuroph...
RATIONALE The majority of drug abusers are incapable of sustaining abstinence over any length of time. Accumulating evidence has linked intense and involuntary craving, Impulsive decision-making and mood disturbances to risk for relapse. However, little is known about temporal changes of these neuropsychological functions in methamphetamine (METH)-dependent individuals. OBJECTIVES To investig...
