Psychoticism and neuroticism predict cocaine dependence and future cocaine use via different mechanisms

James J. Prisciandaro, Aimee L. McRae-Clark, Megan M. Moran-Santa Maria, Karen J. Hartwell, Kathleen T. Brady
2011 Drug and Alcohol Dependence  
Background-Personality characteristics have been associated with cocaine use. However, little is known about the mechanisms through which personality could impact drug use. The present study investigated the cross-sectional and prospective relationships between personality dimensions (i.e., impulsivity, neuroticism) and problematic cocaine use. Reactivity to a pharmacological stressor as a potential mediator of the relationship between neuroticism and future cocaine use was also examined.
more » ... s-Participants were 53 cocaine-dependent individuals and 47 non-dependent controls. Subjects completed the Eysenck Personality Questionnaire (EPQ) at baseline and were administered i.v. corticotrophin releasing hormone (CRH; 1 μg/kg). Cocaine use in the 30 days following CRH administration was measured. Results-Cocaine-dependent individuals had higher scores on the psychoticism (i.e., impulsivity, aggression; p = 0.02) and neuroticism (p < 0.01) scales of the EPQ than nondependent controls. Cocaine-dependent individuals also had a greater subjective stress response to CRH than controls (p < 0.01). Cocaine-dependent individuals with elevated psychoticism used significantly more cocaine over the follow-up period (p < 0.05), whereas individuals with elevated neuroticism trended towards using cocaine more frequently over the follow-up (p = 0.07). Finally, there was a trend for an indirect effect of neuroticism on frequency of cocaine use through subjective reactivity to CRH. Conclusions- The findings extend past research on the association between personality and cocaine use, and suggest that motives for cocaine use may systematically vary across personality characteristics. Moreover, tailoring therapeutic interventions to individuals' personalities may be an area that warrants further investigation.

Alcohol-Induced Stimulation Mediates the Effect of aGABRA2SNP on Alcohol Self-Administrated among Alcohol-Dependent Individuals

Stephen J. Boyd, Joseph P. Schacht, James J. Prisciandaro, Konstantin Voronin, Raymond F. Anton
2016 Alcohol and Alcoholism  
A single-nucleotide polymorphism (SNP) in GABRA2 (rs279858) may moderate subjective response (SR) to alcohol. Results of studies in non-dependent drinkers examining this GABRA2 SNP on SR have been equivocal. This study examined this SNP's direct and indirect effects on alcohol self-administration in dependent drinkers. Method: The sample consisted of 63 Caucasian, non-treatment-seeking individuals with alcohol dependence. Subjective stimulation was assessed using the Biphasic Alcohol Effects

Participants were subsequently offered the opportunity to self-administer up to eight additional drinks. Results: Controlling for baseline stimulation, T-allele homozygotes, relative to individuals with at least one copy of the C-allele, reported greater initial stimulation, t(58) = 2.011, p = 0.049. Greater stimulation predicted greater subsequent alcohol self-administration, t(57) = 2.522, p = 0.015. Although rs279858 genotype did not directly impact self-administration (t(57) = −0.674, p = 0.503), it did have an indirect effect (95% confidence interval [0.068, 1.576]), such that T-allele homozygotes reported greater stimulation, which in turn predicted greater self-administration. Conclusion: These results suggest that the influence of this SNP on SR differs depending on dose or stage of dependence. This study is the first to demonstrate an indirect effect of rs279858 genotype on drinking through SR. Although C-allele carriers have been shown to have an increased risk for alcohol dependence, in our dependent sample, greater stimulation was found among T-allele homozygotes, suggesting that the influence of SR on developing and maintaining dependence differs based on rs279858 genotype. This study demonstrates an indirect effect of rs279858 genotype on drinking through SR. Although C-allele carriers have an increased risk for alcohol dependence, in our dependent sample, greater stimulation was found among T-allele homozygotes, suggesting that the influence of SR on developing dependence differs based on rs279858 genotype.

2013 Psychology of Addictive Behaviors  
Technical advances allowing for the analysis of fMRI results in real-time have led to studies exploring the ability of individuals to use neural feedback signals to modify behavior and regional brain activation. The use of real-time fMRI (rtfMRI) feedback has been explored for therapeutic benefit in a number of disease states, but to our knowledge the potential therapeutic benefit of rtfMRI feedback in the treatment of addictive disorders has not been explored. This manuscript will provide an

We also describe a series of pilot studies that highlight some of the technical challenges in developing a rtfMRI feedback paradigm for use in addictions, specifically in nicotine dependence. Because the use of rtfMRI feedback is in its infancy, the work described is focused on establishing some of the basic parameters in optimizing the rtfMRI feedback, such as the type of feedback signal, region of interest for feedback and predicting which subjects are most likely to respond well to training. While rtfMRI feedback remains an intriguing possibility for the treatment of addictions, much work remains to be done in establishing its efficacy. Development of Real-time fMRI Feedback: An Overview For the past decade, magnetic resonance imaging (MRI) has been the dominant imaging tool for brain research. Unlike older brain imaging techniques such as positron emission tomography (PET) or single photon emission computed tomography (SPECT), MRI does not use ionizing radiation so it is a relatively low-risk procedure that can be conducted repeatedly without fear of increasing radiation load. In addition, MRI has high spatial resolution and allows for imaging the entire brain in only a few seconds. Initially, MRI was used to examine the structure of the brain, and PET or SPECT were the "tools of choice" for imaging the brain function. However, in the mid-1990's using a technique called blood oxygen level dependent imaging (BOLD), researchers discovered that they could use MRI to image a variant of hemoglobin that changed locally reflecting different activity of the brain. This finding allowed MRI studies to gather information about brain function (fMRI) as well as structure. Because BOLD changes are not very large (approximately 0.5-3% of baseline), early functional MRI studies (fMRI) could not make statements about a single individual. It

Neurofeedback delivered via real-time functional magnetic resonance imaging (rtfMRI) is a promising therapeutic technique being explored to facilitate self-regulation of craving in nicotine-dependent cigarette smokers. The current study examined the role of nicotine-dependence severity and the efficacy of multiple visits of neurofeedback from a single region of interest (ROI) in the anterior cingulate cortex (ACC) on craving reduction. Methods: Nine nicotine-dependent cigarette smokers

When viewing smoking-related images with instructions to "crave," patient-tailored ROIs were generated in the vicinity of the ACC. Activity levels from the ROI were fed back while participants viewed smoking cues with the instruction to reduce craving. results: Neurofeedback from a single ROI in the ACC led to consistent decreases in self-reported craving and activation in the ACC across the three visits. Dependence severity predicted response to neurofeedback at Visit 3. Conclusions: This study builds upon previous rtfMRI studies on the regulation of nicotine craving in demonstrating that feedback from the ACC can reduce activation to smoking cues across three separate visits. Individuals with lower nicotine-dependence severity were more successful in reducing ACC activation over time. These data highlight the need to consider dependence severity in developing more individualized neurofeedback methods.
