ABSTRACT The prevalence of lifetime alcohol abuse and/or dependence (alcoholism) in patients with bipolar disorder has been reported to be higher than in all other axis I psychiatric diagnoses. This study examined gender-specific relationships between alcoholism and bipolar illness, which have previously received little systematic study.
The prevalence of lifetime alcoholism in 267 outpatients enrolled in the Stanley Foundation Bipolar Network was evaluated by using the Structured Clinical Interview for DSM-IV. Alcoholism and its relationship to retrospectively assessed measures of the course of bipolar illness were evaluated by patient-rated and clinician-administered questionnaires.
As in the general population, more men (49%, 57 of 116) than women with bipolar disorder (29%, 44 of 151) met the criteria for lifetime alcoholism. However, the risk of having alcoholism was greater for women with bipolar disorder (odds ratio=7.35) than for men with bipolar disorder (odds ratio=2.77), compared with the general population. Alcoholism was associated with a history of polysubstance use in women with bipolar disorder and with a family history of alcoholism in men with bipolar disorder.
This study suggests that there are gender differences in the prevalence, risk, and clinical correlates of alcoholism in bipolar illness. Although this study is limited by the retrospective assessment of illness variables, the magnitude of these gender-specific differences is substantial and warrants further prospective study.

    ABSTRACT: This paper reviews the literature investigating relapse to alcohol and drug use among individuals dually diagnosed with a substance use and a co-occurring mood, anxiety, schizophrenia-spectrum, or personality disorder. Prevalence rates for each co-occurring set of disorders are discussed, followed by research studies that examine predictors of relapse to substance use within these groups. Relevant conceptual models well-suited to incorporating relapse as an outcome variable, and psychiatric factors both as predictor and outcome variables, are presented. Suggestions for future studies are provided. A priority area is developing and using consistent and well-articulated definitions of relapse across studies. Several diagnostic issues surfaced such as using structured clinical interviews to determine diagnosis (preferably following detoxification from alcohol and/or drugs), separating individuals with only alcohol use disorders from those with alcohol and drug use disorders in analyses, reporting the rates and types of overlap in mental health diagnoses, and conducting analyses that include and exclude multiply disordered individuals. Finally, future studies that focus on isolating predictors of relapse and abstinence could make substantive contributions to improving treatment for individuals with co-occurring substance use and mental health disorders.

    ABSTRACT: Background: Up to 60% of bipolar disorder (BD) patients develop alcohol use disorders (AUD) at some point in their lives. The causes of this highly prevalent comorbidity are unknown. High trait impulsivity characterizes both isolated BD and AUD and may be a link to explain the association between BD and AUD. In this study, our aims were to investigate whether BD patients with comorbid AUD would present higher trait impulsivity levels compared to BD patients without comorbid AUD, and whether trait impulsivity levels differ within subgroups of BD according to the subcategory of AUD (abuse vs. dependence, alcoholism alone vs. alcoholism plus drug use disorders). Sampling and Methods: Forty-seven outpatients with BD with comorbid AUD (alcoholic BD group) were compared to 66 outpatients with BD alone (nonalcoholic BD group) and to 90 healthy controls (HC). BD and AUD diagnoses were obtained using the Structured Clinical Interview for DSM-IV diagnoses. Impulsivity was assessed using the Barratt Impulsiveness Scale (BIS-11), a self-report instrument that measures trait impulsivity in three domains: nonplanning, attentional and motor. Results: Alcoholic BD patients scored significantly higher than nonalcoholic BD and HC on the total and on each subscale BIS scores. Within the alcoholic BD patients, alcohol abusers and alcohol dependents did not statistically differ from each other on the BIS-11 scores. BD patients with AUD plus drug use disorders presented statistically higher nonplanning impulsivity than BD patients with AUD alone. Conclusions: This was a cross-sectional study and causal inferences about the relationship between impulsivity and the comorbidity phenomenon cannot be made. Increased impulsivity may be a trait marker for the co-occurrence between BD and AUD, and mediate some severe manifestations of this comorbidity. Copyright (C) 2012 S. Karger AG, Basel

    ABSTRACT: Sex differences have been observed in mania phenotypes in humans. However the mechanisms underlying this difference are poorly understood. Activating the lateral hypothalamus is implicated in manic-like behaviors in rodents. Using newly established lateral hypothalamus kindled (LHK) rat mania model, we investigated sex differences of manic-like behaviors and its correlation with voluntary ethanol intake. We stimulated the lateral hypothalamus bilaterally in the male and female Wistar rats over five consecutive days. We recorded and quantified kindling-induced behaviors for each individual animal. We also assessed ethanol consumption using a two-bottle choice ethanol drinking as well as circadian locomotor activity counts daily throughout the experiment. We found notable sex differences in several aspects of manic-like behaviors during kindling. Males exhibited a significantly increased locomotor activity during the light phase, and reduced rest interval. On the other hand, females displayed significantly higher ethanol consumption and more frequent rearing behavior. However, no sex differences were present in the duration of sexual, feeding or grooming behaviors or in dark-phase activity counts. The excessive alcohol intake in LHK female rats is reminiscent of clinically reported sex differences in bipolar patients while the other phenotypic sex differences such as rearing and locomotor activity are less clearly described in clinical studies. Overall, our results lend further evidence for the validity of the LHK rat as a useful model to study brain region-specific molecular changes during mania and its correlation with alcohol use disorders.
