Correction of depression-associated circadian rhythm abnormalities is associated with lithium response in bipolar disorder.

BACKGROUND: Bipolar disorder (BD) is characterized by episodes of depression and mania and disrupted circadian rhythms. Lithium is an effective therapy for BD, but only 30%-40% of patients are fully responsive. Preclinical models show that lithium alters circadian rhythms. However, it is unknown if the circadian rhythm effects of lithium are essential to its therapeutic properties. METHODS: In secondary analyses of a multi-center, prospective, trial of lithium for BD, we examined the relationship between circadian rhythms and therapeutic response to lithium. Using standardized instruments, we measured morningness, diurnal changes in mood, sleep, and energy (circadian rhythm disturbances) in a cross-sectional study of 386 BD subjects with varying lithium exposure histories. Next, we tracked symptoms of depression and mania prospectively over 12 weeks in a subset of 88 BD patients initiating treatment with lithium. Total, circadian, and affective mood symptoms were scored separately and analyzed. RESULTS: Subjects with no prior lithium exposure had the most circadian disruption, while patients stable on lithium monotherapy had the least. Patients who were stable on lithium with another drug or unstable on lithium showed intermediate levels of disruption. Treatment with lithium for 12 weeks yielded significant reductions in total and affective depression symptoms. Lithium responders (Li-Rs) showed improvement in circadian symptoms of depression, but non-responders did not. There was no difference between Li-Rs and nonresponders in affective, circadian, or total symptoms of mania. CONCLUSIONS: Exposure to lithium is associated with reduced circadian disruption. Lithium response at 12 weeks was selectively associated with the reduction of circadian depressive symptoms. We conclude that stabilization of circadian rhythms may be an important feature of lithium's therapeutic effects. CLINICAL TRIALS REGISTRY: NCT0127253.

Increasing Confidence Through the Development of a Transition-to-Practice Orientation Program for the Experienced Nurse.

A formalized orientation program for experienced nurses was modeled after a program for new graduate nurses. Within a year, experienced nurses rotated through teaching stations, including simulations of shock and respiratory failure. Participants completed pre- and postsurveys and scored self-confidence on a Likert scale. Surveys showed a significant increase in participants' confidence related to elements in their new role. Future plans include a retention rate comparison of participants in this program versus nonparticipants.

The association between lithium use and neurocognitive performance in patients with bipolar disorder.

Lithium remains the gold standard for the treatment of bipolar disorder (BD); however, its use has declined over the years mainly due to the side effects and the subjective experience of cognitive numbness reported by patients. In the present study, we aim to methodically test the effects of lithium on neurocognitive functioning in the largest single cohort (n = 262) of BD patients reported to date by harnessing the power of a multi-site, ongoing clinical trial of lithium monotherapy. At the cross-sectional level, multivariate analysis of covariance (MANCOVA) was conducted to examine potential group differences across neurocognitive tests [California Verbal Learning Test (CVLT trials 1-5,CVLT delayed recall), Wechsler Digit Symbol, Trail-making Test parts A and B (TMT-A; TMT-B), and a global cognition index]. At the longitudinal level, on a subset of patients (n = 88) who achieved mood stabilization with lithium monotherapy, we explored the effect of lithium treatment across time on neurocognitive functioning. There were no differences at baseline between BD patients that were taking lithium compared with those that were not. At follow-up a significant neurocognitive improvement in the global cognitive index score [F = 31.69; p < 0.001], CVLT trials 1-5 [F = 29.81; p < 0.001], CVLT delayed recall [F = 15.27; p < 0.001], and TMT-B [F = 6.64, p = 0.012] was detected. The cross-sectional and longitudinal (on a subset of 88 patients) investigations suggest that lithium may be beneficial to neurocognitive functioning in patients with BD and that at the very least it does not seem to significantly impair cognition when used therapeutically.

Religiosity and Chance Beliefs in Persons with DSM-IV Pathological Gambling Enrolled in a Longitudinal Follow-Up Study.

This study investigates the association of public, private and intrinsic religiosity and chance beliefs (superstition, illusion of control) with gambling behavior in a longitudinal follow-up study of younger and older adult subjects with DSM-IV pathological gambling (PG) and an older adult comparison group without PG. One-hundred sixty-three subjects were enrolled including 60 younger adults with PG (≥ 18/< 40 years), 53 older adults with PG (≥ 60 years), and 50 older adults without PG (≥ 60). Subjects were assessed at baseline and every 6 months thereafter. The Duke University Religion Index for Religious Assessment and the Drake Beliefs About Chance scales were administered at baseline. Follow-up was a mean (SD) of 2.6 (1.4) years. Older adults with PG scored lower on measures of public and intrinsic aspects of religiosity than older adults without PG, and scored higher on superstition and illusion of control. Older adults with PG also scored higher than younger adults with PG on private and intrinsic religiosity, but not public religiosity. Superstition predicted intrinsic, but not other aspects of religiosity. Importantly, during follow-up, higher levels of public and intrinsic religiosity were protective against problematic (levels 2, 3) gambling; were protective against chronic PG; and were predictive of PG remission status. Lower illusion of control ratings were protective against problematic gambling and chronic PG; lower superstition ratings were predictive of remission. We conclude that higher levels of public and intrinsic religiosity and lower levels of chance beliefs are associated with a more benign PG course.

A prospective follow-up study of younger and older subjects with pathological gambling.

Pathological gambling (PG) is a common and costly public health problem associated with impaired quality of life and high suicide rates. Despite its frequency in the general population, PG course is poorly understood in older adults who are especially vulnerable to its devastating consequences. We enrolled 175 subjects in a longitudinal study of gambling behavior: our case group of 53 older adults with PG (≥ 60 years), and two comparison groups including 72 younger adults with PG (< 40 years) and 50 older adults without PG (≥ 60 years). Subjects with PG met lifetime criteria for DSM-IV PG and had a South Oaks Gambling Screen (SOGS) and National Opinion Research Center DSM Screen for Gambling Problems (NODS) scores ≥ 5. Subjects were evaluated at intake and reassessed every 6 months and drop outs were replaced. Follow-up lasted a mean (SD) of 2.6 (1.4) years. At intake older PGs were more likely to be female, Caucasian, divorced, and to have a lower level of education. Older and younger PGs were similar in gambling severity, but older PGs were more likely to have sought PG treatment. Older PGs had lower rates of lifetime drug use disorders, attention deficit/hyperactivity disorder, and obsessive-compulsive disorder. They preferred slots, were more likely to receive PG treatment, and were less likely to discontinue participation in the study. Week by week gambling activity levels showed a significant general downward movement for older and younger PGs, although there were no differences between the groups. Elders without PG had no change in their level of gambling activity. We conclude that younger and older PGs moved toward a reduced level of gambling activity during follow-up. Our data challenge the notion that PG is chronic and progressive.

Five-year follow-up of people diagnosed with compulsive shopping disorder.

BACKGROUND: The authors assessed clinical symptoms and self-reported shopping and spending behavior in people diagnosed with compulsive shopping (CS) at a 5-year follow-up interview. METHODS: All met the criteria of McElroy et al. for lifetime CS and had the disorder for >1year. Structured and semistructured instruments and self-report questionnaires were used to collect data. RESULTS: Of the original 26 subjects, 17 (65%) were interviewed and are the focus of this report. At follow-up, their ages ranged from 23 to 67years (mean=44years). Lifetime psychiatric comorbidity was common, but few had current psychiatric disorders at follow-up. Interest in shopping and spending decreased for eight (47%), stayed the same for five (29%), and increased for four (24%) subjects. Eleven subjects (65%) reported having attempted to quit their CS and three (18%) reported successfully doing so. Triggers for returning to CS included feelings of pressure/excitement/tension to shop; boredom; negative feelings such as sadness, depression, frustration, or anger; and the desire for positive feelings like happiness, power, or elation. Mean scores on the Compulsive Buying Scale (CBS) and the shopping version of the Yale-Brown Obsessive-Compulsive Scale showed overall improvement in CS symptoms (d=1.16 and d=-1.19, respectively); subjects were also less impulsive (d=-0.48). At baseline and follow-up, those with a lifetime mood disorder tended to have greater CS severity. CONCLUSIONS: While the subjects showed overall improvement, most had ongoing symptoms of CS. The implications of the findings are discussed.

Intergenerational Childhood Maltreatment in Persons with DSM-IV Pathological Gambling and Their First-Degree Relatives.

This study investigates the characteristics of individuals with DSM-IV pathological gambling (PG) who experienced childhood maltreatment and rates of maltreatment occurring in their first-degree relatives (FDRs). 94 subjects with DSM-IV PG, 91 controls, and 312 FDRs were assessed for childhood maltreatment as part of a family study of PG. Maltreatment was evaluated using the Revised Childhood Experiences Questionnaire. The Family Assessment Device was used to evaluate the functionality of the PG subject's (or control's) family of origin. Data were analyzed using logistic regression by the method of generalized estimating equations. Rates of maltreatment were significantly higher in subjects with PG than controls (61 vs. 25 %, P < 0.001). Subjects with PG who experienced maltreatment were more likely to be female, had more severe PG symptoms, had co-occurring mood and anxiety disorders, and reported greater early family life dysfunction than those with PG who did not experience maltreatment. Rates of maltreatment were higher in FDRs of PG subjects than controls (41 vs. 24 %, P = .002). Rates in FDRs of individuals with PG who experienced maltreatment themselves were still higher that in FDRs of those with PG who did not experience maltreatment (50 vs. 28 %, P = .009). The former were also more likely to have anxiety disorders, substance use disorders, and suicide attempts. The results suggest that childhood maltreatment in persons with PG is common and intergenerational. Rates of maltreatment in FDRs of PG subjects are high, particularly among those who experienced abuse. The implications of the findings are discussed.

Age at onset of DSM-IV pathological gambling in a non-treatment sample: Early- versus later-onset.

BACKGROUND: Pathological gambling (PG) is a prevalent and impairing public health problem. In this study we assessed age at onset in men and women with PG and compared the demographic and clinical picture of early- vs. later-onset individuals. We also compared age at onset in PG subjects and their first-degree relatives with PG. METHOD: Subjects with DSM-IV PG were recruited during the conduct of two non-treatment clinical studies. Subjects were evaluated with structured interviews and validated questionnaires. Early-onset was defined as PG starting prior to age 33years. RESULTS: Age at onset of PG in the 255 subjects ranged from 8 to 80years with a mean (SD) of 34.0 (15.3) years. Men had an earlier onset than women. 84% of all subjects with PG had developed the disorder by age 50years. Early-onset subjects were more likely to be male, to prefer action games, and to have substance use disorders, antisocial personality disorder, attention deficit/hyperactivity disorder, trait impulsiveness, and social anxiety disorder. Later-onset was more common in women and was associated with a preference for slots and a history of sexual abuse. CONCLUSIONS: Age at onset of PG is bimodal and differs for men and women. Early-onset PG and later-onset PG have important demographic and clinical differences. The implications of the findings are discussed.

Suicide Ideations, Suicide Attempts, and Completed Suicide in Persons with Pathological Gambling and Their First-Degree Relatives.

We examined the relationship between suicidal ideations and attempts in 95 probands with pathological gambling (PG), 91 controls, and 1075 first-degree relatives. The results were analyzed using logistic regression with generalized estimating equations. Thirty-four PG probands (35.8%) and 4 controls (4.4%) had attempted suicide (OR = 12.12, p < .001); in 13 probands, the attempt occurred before PG onset. Lifetime suicidal ideations occurred in 60 PG probands (63.2%) and 12 controls (13.2%) (OR = 11.29, p < .001). Suicidality in PG probands is a marker of PG severity and is associated with greater psychiatric comorbidity. Offspring of PG probands had significantly higher rates of suicide attempts than control offspring.

The relationship of DSM-IV pathological gambling to compulsive buying and other possible spectrum disorders: results from the Iowa PG family study.

This study investigates the possible relationship between pathological gambling (PG) and potential spectrum disorders including the DSM-IV impulse control disorders (intermittent explosive disorder, kleptomania, pyromania, trichotillomania) and several non-DSM disorders (compulsive buying disorder, compulsive sexual behavior, Internet addiction). PG probands, controls, and their first-degree relatives were assessed with instruments of known reliability. Detailed family history information was collected on relatives who were deceased or unavailable. Best estimate diagnoses were assigned blind to family status. The results were analyzed using logistic regression by the method of generalized estimating equations. The sample included 95 probands with PG, 91 controls, and 1075 first-degree relatives (537 PG, 538 controls). Compulsive buying disorder and having "any spectrum disorder" were more frequent in the PG probands and their first-degree relatives vs. controls and their relatives. Spectrum disorders were significantly more prevalent among PG relatives compared to control relatives (adjusted OR=8.37), though much of this difference was attributable to the contribution from compulsive buying disorder. We conclude that compulsive buying disorder is likely part of familial PG spectrum.

Personality Disorders, Impulsiveness, and Novelty Seeking in Persons with DSM-IV Pathological Gambling and Their First-Degree Relatives.

This study investigates the presence of personality disorders, impulsiveness, and novelty seeking in probands with DSM-IV pathological gambling (PG), controls, and their respective first-degree relatives using a blind family study methodology. Ninety-three probands with DSM-IV PG, 91 controls, and their 395 first-degree relatives were evaluated for the presence of personality disorder with the Structured Interview for DSM-IV Personality. Impulsiveness was assessed with the Barratt Impulsiveness Scale (BIS). Novelty seeking was evaluated using questions from Cloninger's Temperament and Character Inventory. Results were analyzed using logistic regression by the method of generalized estimating equations to account for within family correlations. PG probands had a significantly higher prevalence of personality disorders than controls (41 vs. 7 %, OR = 9.0, P < 0.001), along with higher levels of impulsiveness and novelty seeking. PG probands with a personality disorder had more severe gambling symptoms; earlier age at PG onset; more suicide attempts; greater psychiatric comorbidity; and a greater family history of psychiatric illness than PG probands without a personality disorder. PG relatives had a significantly higher prevalence of personality disorder than relatives of controls (24 vs. 9%, OR = 3.2, P < 0.001) and higher levels of impulsiveness. Risk for PG in relatives is associated with the presence of personality disorder and increases along with rising BIS Non-Planning and Total scale scores. Personality disorders, impulsiveness, and novelty seeking are common in people with PG and their first-degree relatives. The presence of a personality disorder appears to be a marker of PG severity and earlier age of onset. Risk for PG in relatives is associated with the presence of personality disorder and trait impulsiveness. These findings suggest that personality disorder and impulsiveness may contribute to a familial diathesis for PG.

Comparison of low and moderate dosages of extended-release quetiapine in borderline personality disorder: a randomized, double-blind, placebo-controlled trial.

OBJECTIVE: The authors compared the efficacy and tolerability of low and moderate dosages of extended-release quetiapine in adults with borderline personality disorder. METHOD: Ninety-five participants with DSM-IV borderline personality disorder were randomly assigned to receive 150 mg/day of quetiapine (the low-dosage group; N=33), 300 mg/day of quetiapine (the moderate-dosage group; N=33), or placebo (N=29). Total score over time on the clinician-rated Zanarini Rating Scale for Borderline Personality Disorder ("Zanarini scale") was analyzed in a mixed-effects model accounting for informative dropout. RESULTS: Participants in the low-dosage quetiapine group had significant improvement on the Zanarini scale compared with those in the placebo group. Time to response (defined as a reduction of 50% or more on the Zanarini scale total score) was significantly shorter for both the low-dosage quetiapine group (hazard ratio=2.54, p=0.007) and the moderate-dosage quetiapine group (hazard ratio=2.37, p=0.011) than for the placebo group. Among participants who completed the study, 82% in the low-dosage quetiapine group were rated as "responders," compared with 74% in the moderate-dosage group and 48% in the placebo group. Treatment-emergent adverse events included sedation, change in appetite, and dry mouth. The overall completion rate for the 8-week double-blind treatment phase was 67% (67% for the low-dosage quetiapine group, 58% for the moderate-dosage quetiapine group, and 79% for the placebo group). Participants who experienced sedation were more likely to drop out. CONCLUSIONS: Participants treated with 150 mg/day of quetiapine had a significant reduction in the severity of borderline personality disorder symptoms compared with those who received placebo. Adverse events were more likely in participants taking 300 mg/day of quetiapine.

A direct, controlled, blind family study of DSM-IV pathological gambling.

OBJECTIVE: Pathological gambling is a major public health problem. We sought to examine the familiality of pathological gambling and determine patterns of familial aggregation of disorders. METHOD: We assessed probands with DSM-IV pathological gambling, controls, and their first-degree relatives. Detailed family history information was collected on relatives who were deceased or unavailable. RESULTS: Ninety-five pathological gambling probands, 91 controls, and their 1,075 first-degree relatives over age 18 (537 relatives of pathological gambling probands, 538 relatives of controls) were evaluated between February 2005 and June 2010. Relatives were assessed blind to proband status. Best estimate diagnoses were assigned. Rates of lifetime pathological gambling (definite/probable) was significantly greater among the first-degree relatives of probands with pathological gambling than among comparison relatives (11% vs 1%, OR = 8.19, P < .001). The prevalence of pathological gambling and subclinical pathological gambling combined was 16% and 3% in case and control relatives, respectively (OR = 6.57, P < .001). Pathological gambling relatives had higher rates of major depression (OR = 1.49, P < .05), bipolar disorder (OR = 3.82, P < .05), any mood disorder (OR = 1.59, P < .05), social anxiety disorder (OR = 4.76, P < .01), any substance use disorder (OR = 1.47, P < .05), posttraumatic stress disorder (OR = 2.59, P < .05), and antisocial personality disorder (OR = 3.72, P < .001). Antisocial personality disorder (OR = 3.12, P < .01), social anxiety disorder (OR = 4.15, P < .01), and posttraumatic stress disorder (OR = 2.85, P < .05) were more frequent in case relatives independent of the presence of pathological gambling. Age at onset of pathological gambling in case probands (< 40 years/≥ 40 years) was not related to familiality in their first-degree relatives (OR = 1.03, P = .927). CONCLUSIONS: Pathological gambling is familial. Mood and substance use disorders may emerge as a consequence of the pathological gambling or as a more complex syndrome. In contrast, antisocial personality disorder, social anxiety disorder, and posttraumatic stress disorder may share a common familial etiology with pathological gambling. The phenotype may extend beyond pathological gambling to include subclinical forms of the disorder.

Pathological gambling: relationship to obesity, self-reported chronic medical conditions, poor lifestyle choices, and impaired quality of life.

BACKGROUND: Pathological gambling (PG) is an important public health problem that is prevalent, costly to society, and associated with substance misuse, depression, domestic violence, crime, and suicide. Despite these challenges, little is known about the physical health and medical correlates of PG. The goal of this project was to assess self-reported chronic medical conditions, medication usage, lifestyle choices, health care utilization, quality of life variables, and body mass index (BMI) in persons with and without PG. METHODS: Subjects with PG and community controls were systematically assessed for their medical health, lifestyle choices, medication usage, and health care utilization. We administered the Medical Outcome Study Short-Form 36 Health Survey to assess perceived health and quality of life. BMI was calculated for all subjects. Obesity was defined as having a BMI≥30kg/m(2). RESULTS: We compared 95 subjects with DSM-IV PG (South Oaks Gambling Screen [SOGS] score≥5) and 91 control subjects without PG (SOGS≤2) selected through random digit dialing from the general community. PG subjects and controls were similar in age and gender. Persons with PG had more medical and mental health conditions than controls, and were more likely to avoid regular exercise, smoke≥1 pack/day, drink≥5 servings of caffeine daily, and watch television≥20hours/week. They had more emergency department visits for physical and mental health conditions, were more likely to have been psychiatrically hospitalized in the past year, and were more likely to take psychotropic medication. They were less likely to have had regular dental visits and were more likely to put off medical care due to financial problems. Severity of gambling was positively correlated with number of medical conditions. Persons with PG had poorer self-reported health perceptions on all but one SF-36 subscale. Importantly, persons with PG had a higher BMI than controls and were more likely to be obese. CONCLUSIONS: PG is associated with obesity, chronic medical conditions, poor lifestyle choices, worse quality of life, and the use of costly forms of medical care. Pathological gamblers are less likely to receive regular dental care and are more likely to be unable to pay for medical care. The implications of the findings are discussed.

Marital status, childhood maltreatment, and family dysfunction: a controlled study of pathological gambling.

BACKGROUND: Pathological gambling is a prevalent public health problem associated with depression, substance misuse, crime, and suicide. Despite these challenges, little attention has been directed to examining its negative consequences on families and marriages, including divorce rates, childhood maltreatment, and family dysfunction. METHOD: From February 2005 to June 2010, subjects with DSM-IV-defined pathological gambling and community controls were assessed for marital and family variables and indices of childhood maltreatment. The Family Assessment Device (FAD) was used to evaluate family functioning. RESULTS: Ninety-five subjects with DSM-IV pathological gambling and 91 control subjects without pathological gambling were recruited and assessed. They were similar in age, gender, and employment status. Persons with pathological gambling were more likely than controls to have ≥ 1 divorce (odds ratio [OR] = 2.56; 95% CI, 1.35-4.87; P = .004), to live alone (OR = 4.49; 95% CI, 1.97-10.25; P < .001), and to report any type of childhood maltreatment (OR = 4.02; 95% CI, 2.12-7.64; P < .001). They did not differ on number of siblings or ordinal position among siblings. Pathological gambling subjects reported significantly worse family functioning than control subjects as assessed by all 7 FAD subscales. On the FAD general functioning subscale, 55% of pathological gambling families and 33% of control families were rated "unhealthy" (OR = 2.17; 95% CI, 1.14-4.12; P = .018). Severity of gambling was positively correlated with divorce, childhood maltreatment, and the FAD roles subscale. CONCLUSIONS: People with pathological gambling are more likely than controls to have been divorced, to live alone, and to report having experienced childhood maltreatment than controls. They also report greater family dysfunction.

Prevalence of problem gambling in Iowa: revisiting Shaffer's adaptation hypothesis.

BACKGROUND: Pathological gambling (PG) is an important public health problem. We assessed the prevalence of PG and problem (at-risk) gambling in a random sample of Iowa adults and compared the results to survey data collected in 1989 and 1995. The goal of this study was to examine whether continued expansion of gambling venues is associated with increased rates of problematic gambling behavior. METHODS: A random digit dialing telephone screening was conducted in eastern Iowa of men and women age ≥18. Respondents were administered the South Oaks Gambling Screen (SOGS) to assess lifetime gambling behavior. Demographic and clinical variables were collected. RESULTS: A total of 356 respondents (147 men, 209 women) completed the SOGS, and all reported lifetime gambling participation. PG (SOGS ≥5) was found in 5 (1.4%) and problem gambling (SOGS = 3, 4) in 8 (2.2%) respondents. Disordered gambling (SOGS ≥3) was found in 13 (3.6%) respondents. Risk factors for disordered gambling included age (odds ratio [OR] = 0.64 per 10-year age increase), income (OR = 0.82 per $10,000 increase), minority group status (OR = 5.75), number of lifetime gambling activities (OR = 1.27), and having ever gambled ≥$100 (OR = 13.3). Overall gambling participation was significantly less in the current sample, compared with data collected in 1995. CONCLUSIONS: Recent gambling participation was less than in 1995, despite the continued expansion of gaming opportunities. Disordered gambling was associated with younger age, lower income, and minority group status. The results are consistent with Shaffer's "adaptation" hypothesis, which posits that following an initial increase in gambling participation, problematic gambling stabilizes at a lower level.

Neuropsychological performance, impulsivity, ADHD symptoms, and novelty seeking in compulsive buying disorder.

We examined the neuropsychological performance of people with compulsive buying disorder (CBD) and control subjects, along with trait impulsivity, symptoms of attention deficit hyperactivity disorder (ADHD), and selected personality characteristics. Subjects received a comprehensive neuropsychological test battery, depression and ADHD symptom assessment, the Barratt Impulsiveness Scale, and a version of the Temperament and Character Inventory. Persons with CBD (n=26) and controls (n=32) were comparable in terms of age, sex, and years of education. Subjects with CBD had a mean age of 36.3 years (S.D.=15.7) and an age at onset of 19.7 years (S.D.=7.0). Compulsive buyers had more lifetime mood, anxiety, and impulse control disorders. People with Compulsive buying performed significantly better on the Wechsler Abbreviated Scale of Intelligence Picture Completion task, a test of visual perception; otherwise, there were no consistent differences in neuropsychological measures. They also had elevated levels of self-reported depression, ADHD symptoms, trait impulsivity, and novelty seeking. In conclusion, compulsive buyers have greater lifetime psychiatric comorbidity than controls, and higher levels of self-rated depression, ADHD symptoms, trait impulsivity, and novelty seeking. The present study does not support the notion that there is a pattern of neuropsychological deficits associated with CBD.

An open-label trial of acamprosate in the treatment of pathological gambling.

BACKGROUND: The efficacy and tolerability of acamprosate has been tested in the treatment of pathological gambling (PG). Acamprosate is known to reduce alcohol craving and use in persons with alcohol dependence, and it has been hypothesized that the drug would have a similar effect in individuals with PG. METHODS: Participants with DSM-IV criteria for PG received acamprosate in an 8-week, open-label trial following a 2-week observation. The primary efficacy measure was the Yale-Brown Obsessive Compulsive Scale modified for PG (Y-BOCS-PG). Secondary efficacy measures included the Gambling Severity Assessment Scale (GSAS), the Clinical Global Impression (CGI) Improvement and Severity Scales, a patient self-rated global rating, the Hamilton Depression Rating Scale (HDRS), the Sheehan Disability Scale (SDS), and the Timeline Follow Back (TLFB). The study was conducted at 2 sites. RESULTS: Twenty-six participants (11 men, 15 women) had at least 1 post-baseline visit and were included in the analysis. Twenty participants (77%) completed the protocol. Significant improvement was observed in Y-BOCS-PG and GSAS scores, both CGI scales, a patient self-rated global scale, all 3 SDS subscales, and number of gambling episodes. Seventeen participants (65%) were considered responders (ie, achieved "much" or "very much" improvement). Improvements on the HDRS, in money wagered, and in time spent gambling were not significant. Few adverse events were reported. CONCLUSIONS: The results suggest that acamprosate is well tolerated and may be effective in the treatment of PG.

Pathological gambling and compulsive buying: do they fall within an obsessive-compulsive spectrum?

Both compulsive buying (CB) and pathological gambling (PG) have been proposed as members of a spectrum of disorders related to obsessive-compulsive disorder (OCD). The spectrum hypothesis originated in the early 1990s and has gained considerable support, despite the lack of empirical evidence. Interest in this hypothesis has become critical because some investigators have recommended the creation of a new category that includes these disorders in DSM-5, now under development. In this article, the authors describe the origin of the obsessive-compulsive (OC) spectrum and its theoretical underpinnings, review both CB and PG, and discuss the data both in support of and against an OC spectrum. Both disorders are described in terms of their history, definition, classification, phenomenology family history, pathophysiology, and clinical management. The authors conclude that: (i) CB and PG are probably not related to OCD, and there is insufficient evidence to place them within an OC spectrum in DSM-V; (ii) PG should stay with the impulse-control disorders (ICDs); and (iii) a new diagnosis of CB should be created and be classified as an ICD.
