Self-medication of mood disorders with alcohol and drugs in the National Epidemiologic Survey on Alcohol and Related Conditions

Journal of Affective Disorders Volume 115, Issue 3, Pages 367-375 (June 2009)

Almost one-quarter of individuals with mood disorders (24.1%) used alcohol or drugs to relieve symptoms. The highest prevalence of self-medication was seen in bipolar I disorder (41.0%). Men were more than twice as likely as women to engage in self-medication (Adjusted Odds Ratio=2.18; 95% Confidence Interval 1.90–2.49).

After controlling for the effects of substance use disorders, self-medication was associated with higher odds of comorbid anxiety and personality disorders when compared to individuals who did not self-medicate.

Self-Control in Decision-Making Involves Modulation of the vmPFC Valuation System

Science 1 May 2009:Vol. 324. no. 5927, pp. 646 - 648

Every day, individuals make dozens of choices between an alternative with higher overall value and a more tempting but ultimately inferior option. Optimal decision-making requires self-control.

We propose two hypotheses about the neurobiology of self-control: (i) Goal-directed decisions have their basis in a common value signal encoded in ventromedial prefrontal cortex (vmPFC), and (ii) exercising self-control involves the modulation of this value signal by dorsolateral prefrontal cortex (DLPFC).

We used functional magnetic resonance imaging to monitor brain activity while dieters engaged in real decisions about food consumption.

Activity in vmPFC was correlated with goal values regardless of the amount of self-control. It incorporated both taste and health in self-controllers but only taste in non–self-controllers. Activity in DLPFC increased when subjects exercised self-control and correlated with activity in vmPFC.

Amygdala protein kinase C epsilon controls alcohol consumption

Genes, Brain and Behavior Published Online: 19 Feb 2009

Alcoholism is a progressive disorder that involves the amygdala. Mice lacking protein kinase C epsilon (PKCɛ) show reduced ethanol consumption, sensitivity and reward. We therefore investigated whether PKCɛ signaling in the amygdala is involved in ethanol consumption.

Local knockdown of PKCɛ in the amygdala reduced ethanol consumption and preference in a limited-access paradigm. Further, mice that are heterozygous for the PKCɛ allele consume less ethanol compared with wild-type mice in this paradigm. These mice have a >50% reduction in the abundance of PKCɛ in the amygdala compared with wild-type mice.

We conclude that amygdala PKCɛ is important for ethanol consumption in mice.

Protracted Withdrawal from Alcohol and Drugs of Abuse Impairs Long-Term Potentiation of Intrinsic Excitability in the Juxtacapsular Bed Nucleus of the Stria Terminalis

The Journal of Neuroscience, April 29, 2009, 29(17):5389-5401

The juxtacapsular bed nucleus of the stria terminalis (jcBNST) is activated in response to basolateral amygdala (BLA) inputs through the stria terminalis and projects back to the anterior BLA and to the central nucleus of the amygdala.

Here we show a form of long-term potentiation of the intrinsic excitability (LTP-IE) of jcBNST neurons in response to high-frequency stimulation of the stria terminalis. This LTP-IE, which was characterized by a decrease in the firing threshold and increased temporal fidelity of firing, was impaired during protracted withdrawal from self-administration of alcohol, cocaine, and heroin. Such impairment was graded and was more pronounced in rats that self-administered amounts of the drugs sufficient to maintain dependence.

Dysregulation of the corticotropin-releasing factor (CRF) system has been implicated in manifestation of protracted withdrawal from dependent drug use. Administration of the selective corticotropin-releasing factor receptor 1 (CRF1) antagonist R121919 [2,5-dimethyl-3-(6-dimethyl-4-methylpyridin-3-yl)-7-dipropylamino-pyrazolo[1,5-a]pyrimidine)], but not of the CRF2 antagonist astressin2-B, normalized jcBNST LTP-IE in animals with a history of alcohol dependence; repeated, but not acute, administration of CRF itself produced a decreased jcBNST LTP-IE.

Thus, changes in the intrinsic properties of jcBNST neurons mediated by chronic activation of the CRF system may contribute to the persistent emotional dysregulation associated with protracted withdrawal.

Hierarchical additive modeling of nonlinear association with spatial correlations - An application to relate alcohol outlet density and neighborhood assault rates

Statistics in Medicine Published Online: 28 Apr 2009

We propose a hierarchical additive model, where the nonlinear correlations and the complex interaction effects are modeled using the multiple additive regression trees and the residual spatial association in the assault rates that cannot be explained in the model are smoothed using a conditional autoregressive (CAR) method.

We develop a two-stage algorithm that connects the nonparametric trees with CAR to look for important covariates associated with the assault rates, while taking into account the spatial association of assault rates in adjacent census tracts.

The proposed method is applied to the Los Angeles assault data (1990-1999). To assess the efficiency of the method, the results are compared with those obtained from a hierarchical linear model.

How do people recover from alcohol dependence? A systematic review of the research on mechanisms of behavior change in Alcoholics Anonymous
Addiction Research & Theory, Volume 17, Issue 3 June 2009 , pages 236 - 259

Results suggest AA helps individuals recover through common process mechanisms associated with enhancing self-efficacy, coping skills, and motivation, and by facilitating adaptive social network changes. Little research or support was found for AA's specific practices or spiritual mechanisms. Conclusions are limited by between-study differences in sampling, measurement, and assessment time-points, and by insufficient theoretical elaboration of recovery-related change. Similar to the common finding that theoretically-distinct professional interventions do not result in differential patient outcomes, AA's effectiveness may not be due to its specific content or process. Rather, its chief strength may lie in its ability to provide free, long-term, easy access and exposure to recovery-related common therapeutic elements, the dose of which, can be adaptively self-regulated according to perceived need.

Alcohol Use and Its Role in Female Homicides in the Western Cape, South Africa

J. Stud. Alcohol Drugs 70: 321-327, 2009

Sixty-two percent of women who were murdered had a high BAC at the time of their death, with an overall median BAC of .11% (110 mg/100 ml). A quantile regression analysis showed that a raised median BAC at the time of death was positively associated with the victim's age; being unemployed or not known to be employed; and being killed in a rural setting, in a public space, and on a weekend.

Significant interactions between type of homicide and employment showed a modification in median BACs for unemployed victims killed by intimate partners compared with employed victims, with a median difference of .19% (190 mg/100 ml) (95% confidence interval: .14%-.23% [140-230 mg/100 ml]).

Ethanol inhibition of aspartyl-asparaginyl-β-hydroxylase in fetal alcohol spectrum disorder: Potential link to the impairments in central nervous system neuronal migration

Alcohol Volume 43, Issue 3, May 2009, Pages 225-240

Chronic gestational exposure to ethanol caused dose-dependent impairments in neuronal migration and corresponding reductions in AAH protein expression in developing cerebella.

In addition, prenatal ethanol exposure inhibited insulin and IGF-I–stimulated directional motility in isolated cerebellar granule neurons. Ethanol-treated neuronal cultures (50 mM × 96 h) also had reduced levels of AAH protein. Mechanistically, we showed that AAH protein could be phosphorylated on Ser residues by GSK-3β, and that chemical inhibition of GSK-3β and/or global Caspases increases AAH protein in both control- and ethanol-exposed cells.

Ethanol-impaired neuronal migration in FASD is associated with reduced AAH expression. Because ethanol increases the activities of both GSK-3β and Caspases, the inhibitory effect of ethanol on neuronal migration could be mediated by increased GSK-3β phosphorylation and Caspase degradation of AAH protein.

The Adolescent Substance Abuse Prevention Study: A randomized field trial of a universal substance abuse prevention program
Drug and Alcohol Dependence Volume 102, Issues 1-3, 1 June 2009, Pages 1-10

The purpose of the study was to determine whether a universal school-based substance abuse prevention program, Take Charge of Your Life (TCYL), prevents or reduces the use of tobacco, alcohol, or marijuana

The negative impact of the program on baseline nonusers of alcohol and tobacco indicate that TCYL should not be delivered as a universal prevention intervention. The finding of a beneficial effect for baseline marijuana users further supports this conclusion. The programmatic and methodological challenges faced by the Adolescent Substance Abuse Prevention Study (ASAPS) and lessons learned offer insights for prevention researchers who will be designing similar randomized field trials in the future.

Universal school-based substance abuse prevention programs: Modeling targeted mediators and outcomes for adolescent cigarette, alcohol and marijuana use

Drug and Alcohol Dependence Volume 102, Issues 1-3, 1 June 2009, Pages 19-29

Relationships among targeted constructs and outcomes differed for each of the drugs with communication skills having a potentially iatrogenic effect on alcohol use. Program targets were mediated through the intentions to use these substances. Finally, we found evidence of a moderating effect of decision-making skills on perceptions of harm and attitudes toward use, depending upon the outcome.

Prevention curricula may need to target specific drugs. In addition to normative beliefs, perceptions of harm, and refusal and decision-making skills, programs should directly target constructs proximal to behavioral outcomes such as attitudes and intentions. Finally, more research on the effects of communication skills on adolescent substance use should be examined.
