Defining and validating bipolar disorder in the preschool period.

The clinical characteristics and adaptive functioning of preschoolers who met DSM-IV criteria for bipolar disorder versus psychiatric and healthy comparison groups were investigated. A community-based sample of 303 preschoolers (3-6 years of age) and their caregivers was ascertained. Diagnostic classification based on parent report of mania symptoms was made using an age-appropriate psychiatric interview. Results indicated that 26 preschoolers met DSM-IV criteria for bipolar disorder who could be identified based the presence of 13 core age-adjusted mania items. These children could be clearly differentiated from children in two psychiatric groups (DSM-IV disruptive disorders, and major depressive disorder) and a "healthy" comparison group based on a specific symptom constellation. Findings indicated that preschoolers in the bipolar group were significantly more (p < .05) impaired than the two psychiatric and healthy groups based on independent measures. Further, even after controlling for comorbid attention-deficit/hyperactivity disorder (81% comorbidity rate), the bipolar group remained significantly (p < .05) more impaired in multiple domains compared to preschoolers with DSM-IV disruptive disorders and healthy controls. Findings suggested that children as young as 3 years can manifest DSM-IV bipolar disorder when age adjusted symptom descriptions are employed, and that these children can be distinguished from healthy and disruptive disordered preschoolers. Recommendations for future research in this area that integrates developmental and mental health models are made.

Risperidone in cocaine-dependent patients with comorbid psychiatric disorders.

BACKGROUND: : A high percentage of individuals with cocaine dependence have a comorbid psychiatric illness, which complicates treatment of the substance abuse. This report will describe clinical experience using risperidone in cocaine-dependent patients with psychiatric disorders. METHOD: : Sixteen male patients with cocaine dependence and comorbid psychiatric disorder (DSM-III-R) diagnoses, who were admitted to a voluntary, post-detoxification, intermediate-care inpatient substance abuse program, were started on risperidone (mean starting dose 2.3 mg/day) in an open-label, naturalistic trial. Patients were assessed weekly using the Clinical Global Impressions scale to assess overall functioning, a Likert scale for craving, the Abnormal Involuntary Movement Scale, interviews with substance abuse counselors and patients, and laboratory tests. All patients had at least one other substance use diagnosis besides cocaine dependence, and 13 patients were taking another psychiatric medication. RESULTS: : Of the 16 patients, 13 (81%) were rated improved or much improved on the CGI scale, and all patients reported mild or no craving at the last assessment (after a mean of 32.6 days of risperidone treatment). No patient developed extrapyramidal symptoms or hypomania. Compared to a 32% historical completion rate for patients receiving treatment as usual, fourteen (88%) of these patients completed the program, and 9 moved on to the next level of care. CONCLUSION: : The results of this naturalistic trial suggest that risperidone is safe and well tolerated in patients with cocaine dependence and comorbid psychiatric illness. In the short term, risperidone may also be effective in reducing cocaine craving and use and may increase the likelihood of completing substance abuse treatment.

The evolution of hyperactivity, impulsivity and cognitive diversity.

The evolutionary status of attention deficit/hyperactivity disorder (ADHD) is central to assessments of whether modern society has created it, either physically or socially; and is potentially useful in understanding its neurobiological basis and treatment. The high prevalence of ADHD (5-10%) and its association with the seven-repeat allele of DRD4, which is positively selected in evolution, raise the possibility that ADHD increases the reproductive fitness of the individual, and/or the group. However, previous suggestions of evolutionary roles for ADHD have not accounted for its confinement to a substantial minority. Because one of the key features of ADHD is its diversity, and many benefits of population diversity are well recognized (as in immunity), we study the impact of groups' behavioural diversity on their fitness. Diversity occurs along many dimensions, and for simplicity we choose unpredictability (or variability), excess of which is a well-established characteristic of ADHD.Simulations of the Changing Food group task show that unpredictable behaviour by a minority optimizes results for the group. Characteristics of such group exploration tasks are risk-taking, in which costs are borne mainly by the individual; and information-sharing, in which benefits accrue to the entire group. Hence, this work is closely linked to previous studies of evolved altruism.We conclude that even individually impairing combinations of genes, such as ADHD, can carry specific benefits for society, which can be selected for at that level, rather than being merely genetic coincidences with effects confined to the individual. The social benefits conferred by diversity occur both inside and outside the 'normal' range, and these may be distinct. This view has the additional merit of offering explanations for the prevalence, sex and age distribution, severity distribution and heterogeneity of ADHD.

Personality disorders.

There is considerably less research on the treatment of personality disorders than most other disorders in psychiatry such as depression, anxiety or schizophrenia. There are several published review papers on research of the treatment of these disorders. The present brief survey will deal with the treatment of syndromes for which there is some research evidence of efficacy; for the most part, it deals with the treatment of unwanted emotions and behaviors that can occur in more than one diagnostic category.

Proton magnetic resonance spectroscopy of bipolar disorder versus intermittent explosive disorder in children and adolescents.

OBJECTIVE: The diagnosis of bipolar disorder in juveniles is controversial. This study was designed to compare proton magnetic resonance spectroscopy ((1)H MRS) in patients with bipolar disorder or intermittent explosive disorder, two groups with symptomatic overlap but categorical distinction. Children with intermittent explosive disorder designate patients whose illness clinically resembles pediatric bipolar disorder but does not satisfy DSM-IV criteria for mania. Based on the authors' previous report of higher levels of (1)H MRS cingulate myo-inositol/creatine in youngsters with bipolar disorder than in normal comparison subjects, they hypothesized that patients with bipolar disorder would have higher cingulate myo-inositol/creatine-phosphocreatine measurements than patients with intermittent explosive disorder and normal comparison subjects. METHOD: Myo-inositol levels were measured with a 2x2x2 cm(3) voxel placed in the anterior cingulate for acquisition of (1)H MRS in 10 patients with bipolar disorder, 10 patients with intermittent explosive disorder, and 13 normal comparison subjects. N-Acetylaspartate, choline moieties, creatine-phosphocreatine, and glutamate-glutamine metabolite levels were also measured. RESULTS: The patients with bipolar disorder showed significantly higher anterior cingulate myo-inositol/creatine-phosphocreatine and myo-inositol (mmol/liter) levels than the patients with intermittent explosive disorder and the normal comparison subjects. No significant differences were found across groups for myo-inositol or other metabolites in the occipital cortex. CONCLUSIONS: These data provide evidence that differences in the concentration of myo-inositol (mmol/liter) in the anterior cingulate cortex in (1)H MRS may differentiate these two populations. Follow-up studies involving larger samples may conclusively estimate the biological specificity between pediatric bipolar disorder and other disorders, which overlap clinically.

Does sustained-release lithium reduce impulsive gambling and affective instability versus placebo in pathological gamblers with bipolar spectrum disorders?

OBJECTIVE: Selective serotonin reuptake inhibitors may be effective for some patients with pathological gambling, but those with comorbid conditions, such as bipolar spectrum disorders, may relapse during treatment. To the authors' knowledge, this is the first placebo-controlled treatment study in pathological gamblers with bipolar spectrum disorders; it compares sustained-release lithium carbonate to placebo. METHOD: Forty pathological gambling patients with bipolar spectrum disorders entered a 10-week randomized, double-blind, placebo-controlled treatment study of sustained-release lithium carbonate. Outcome measures included gambling severity, mood, anxiety, and impulsivity scales. RESULTS: Pathological gambling patients with bipolar spectrum disorders significantly improved while taking sustained-release lithium carbonate compared to placebo on total pathological gambling scores on the Yale-Brown Obsessive Compulsive Scale, including both thoughts/urges and behavior, as well as on the Clinical Global Impression severity of pathological gambling scale. Affective instability (the Clinician-Administered Rating Scale for Mania score) was also lower in the group treated with sustained-release lithium carbonate compared to placebo. Ten (83%) of 12 completers were rated as responders in the sustained-release lithium group versus five (29%) of 17 in the placebo group. Of note, improvement in gambling severity was significantly correlated with improvement in mania ratings. CONCLUSIONS: Sustained-released lithium may be an effective treatment in reducing both gambling behavior and affective instability in pathological gamblers with bipolar spectrum disorder. This study highlights the need to identify subgroups of pathological gambling patients with bipolar spectrum conditions because this may have important treatment implications.

Impulse control disorders and attention deficit disorder in pathological gamblers.

Little systematic research has been done on psychiatric comorbidity of pathological gambling, an impulse control disorder. This report describes the occurrence of attention deficit disorder and impulse control disorders in 40 pathological gamblers in treatment for gambling problems and 64 controls. Diagnoses were made by structured interviews which utilized operationalized diagnostic criteria. An impulse control disorder other than pathological gambling was noted in 35% of the pathological gamblers, compared to 3% of the controls (p < .001). Compulsive buying (p < .001) and compulsive sexual behavior (p < .05) were significantly higher in pathological gamblers than controls. A strong association was seen among pathological gambling, attention deficit, and other impulse control disorders. Attention deficit disorder was seen in 20% of the pathological gamblers. Rates of impulse control disorders did not differ by gender. Implications of these high rates of comorbidity are discussed.

Factors at play in faster progression for female pathological gamblers: an exploratory analysis.

BACKGROUND: Previous studies reported a faster progression for alcohol dependence and pathological gambling among females as compared with males. This phenomenon was called the "telescoping effect." By comparing female gamblers with male gamblers regarding gambling preferences and comorbidity, the authors explored potential risk factors for telescoping. METHOD: A consecutive sample of Brazilian treatment-seeking pathological gamblers (DSM-IV criteria) was recruited. Genders were contrasted regarding comorbidity and gambling behavior, controlling for demographics, gambling severity, and previous access to mental health services. RESULTS: Seventy female gamblers and 70 male gamblers were interviewed. A greater proportion of women than men reported electronic bingo and video lottery terminals as their main type of gambling. Gambling was divided in 3 progressive stages: "social gambling," "intense gambling," and "problem gambling." Faster progression for female gamblers was confirmed; female gender and preference for electronic bingo and/or video lottery terminals were risk factors for telescoping throughout all stages. Female gamblers presented a higher comorbidity with depression, whereas male gamblers had higher rates of alcohol dependence. Nevertheless, comorbidity profiles were not related to gambling progression. CONCLUSION: Two factors could be at play for treatment-seeking female gamblers in Brazil: (1) a potential gender vulnerability and (2) a cultural environment yielding them access to a narrower range of gambling games that includes mainly the most addictive ones.

A neuropsychiatric approach to impulse disorders.

Disordered impulse control (or pathologic impulsivity) is a common feature of many neurologic and psychiatric illnesses. Diagnosis is founded on comprehensive neuropsychiatric evaluation. Behavioral dyscontrol often represents pathology at multiple levels of nervous system function and requires an appropriately comprehensive treatment program. Evaluation and diagnostic classification are discussed. Several clinical synopses are presented to illustrate the common complexity of evaluation and treatment in presentations of pathologic impulsivity.

Splitting as a consequence of severe abuse in childhood.

Clinical data suggest that Kernberg's description of splitting as a defense mechanism is useful in conceptualizing the psychological consequences of abuse in childhood in certain patients. The splitting in these patients is similar to his description of splitting in borderline patients in that it compartmentalizes and sequesters certain overwhelming and painful ego states accompanying negative introjects of the betraying primary object and the betrayed self. These sequestered introjects, furthermore, act as automatons, generating behaviors that arbitrarily re-enact their content even though the patient remains consciously unaware of their historical meaning. Another consequence of the sequestration of these traumatic introjects is that their affects retain their initial power and primitive quality, unmodulated by the usual homogenizing process that is a part of the synthesis of part-object introjects into whole-object introjects; the sequestration, therefore, often painful in itself, must nevertheless be rigidly maintained lest traumatic anxiety in the face of overwhelming affects be re-experienced. Shengold calls the sequence of events that results in this brittle but stubborn painful constriction of the personality "soul murder." He borrowed the phrase from Freud who used it to refer to what Schreber had suffered at the hands of his sadistic father. That phrase--"soul murder"--may sound melodramatic, but it powerfully conveys what these patients communicate of their experience of themselves. As with Kernberg's patients, the defensive splitting serves to protect the positive introjects. These patients fear their negative introjects, even more than they feel uncomfortable about the split. They fear their desperate rage will destroy their love objects, and leave them feeling abandoned and hating themselves. As one of my patients put it: "I fear that my destructive anger will leave me all alone in a sea of rubble of my own making." In the transference, he feared destroying me and our positive bond. In these cases it would seem that the turning to splitting occurred at a later age than it does with Kernberg's borderline patients. His proposition is that the developmentally normal "splitting," related to the undifferentiation of the infantile ego, persists as a defensive splitting, perhaps as a consequence of a consistently derailed mother-child dialogue; whereas in my patients it would seem that the normal developmental splitting had waned as ego differentiation proceeded, but that in the face of overwhelming traumata at perhaps 3 or 4 years of age, the primitive defense was invoked regressively.(ABSTRACT TRUNCATED AT 400 WORDS)

Divalproex treatment for youth with explosive temper and mood lability: a double-blind, placebo-controlled crossover design.

OBJECTIVE: The authors sought to replicate open-label findings showing that specific criteria for explosive temper and mood lability identify disruptive youth who improve while receiving the anticonvulsant divalproex sodium. METHOD: Twenty outpatient children and adolescents (ages 10-18) with a disruptive behavior disorder (oppositional defiant disorder or conduct disorder) met the specific criteria for explosive temper and mood lability. They received 6 weeks of divalproex treatment and 6 weeks of placebo by random assignment. Independent evaluators blind to group assignment assessed response at the end of each phase. RESULTS: At the end of phase 1, eight of 10 subjects had responded to divalproex; zero of 10 had responded to placebo. Of the 15 subjects who completed both phases, 12 has superior response taking divalproex. CONCLUSIONS: This preliminary study replicates open-label findings showing that divalproex is an efficacious treatment for explosive temper and mood lability in disruptive children and adolescents.

Impulsivity.

Disorders characterized by impulsivity include disorders of impulse control (intermittent explosive disorder, pyromania, kleptomania, pathological gambling and trichotillomania), paraphilias, sexual impulsions and sexual addictions and impulsive aggression personality disorders (borderline, antisocial, histrionic and narcissistic personality disorders). Impulsivity has a substantial impact on both individuals and society. Impulse control disorders may be conceptualized as a subset of the obsessive-compulsive spectrum. In this article, we examine the genetic and neurobiological aetiology of these disorders and possible treatment options. The link between serotonergic dysfunction and the pathophysiology of impulsivity is discussed, and studies that examine the efficacy of various selective serotonin reuptake inhibitors and other alternatives in the treatment of impulsive disorders such as pathological gambling, sexual addictions and borderline personality disorder are presented.

A short-term longitudinal study of the early development of self-regulation.

A short-term longitudinal study was conducted to determine whether self-regulation at 4 years could be predicted from child and maternal measures obtained when the children were age 24 months. The subjects were 69 children and their mothers drawn from the general community. Criterion behaviors assessed at 4 years were those suggestive of attention-deficit hyperactivity disorder. Of the 24-month child measures, maternal ratings of the child's impulsivity and attention span, plus an objective measure of delay ability, were the most effective predictors. Maternal negativity, as assessed in mother-child interaction, predicted the criterion behaviors, even after the child's behavior as an elicitor of maternal behavior was controlled. Maternal child-rearing attitudes on the dimensions of warmth and aggravation were also effective predictors, even after controlling for the child's emotionality as a possible determinant of maternal attitudes. It is argued that the results with the maternal attitude measures provide support for the hypothesis that maternal behavior is a contributor to the development of self-regulation.

Teacher reports of ADHD symptoms in Italian children at the end of first grade.

OBJECTIVE: To determine the prevalence of teacher-rated ADHD symptoms in Italian first-graders. METHOD: 1891 first-graders aged 6.6-7.4 years were evaluated using a 34-item DSM-IV-referenced ADHD teacher rating questionnaire which included all the 18 DSM-IV ADHD diagnostic criteria, some Oppositional-Defiant Disorder (ODD), Conduct Disorder (CD), depression and anxiety symptoms, and questions about the child's social and scholastic impairment. RESULTS: Criteria for ADHD were met in 7.1% (n=135) of the subjects (10.4% males and 3.8% females), 3.5% with the Inattentive subtype, 2.3% with the Hyperactive/Impulsive subtype and 1.3% with a Combined subtype. Internalizing (depression and/or anxiety) symptoms were reported in 25.9% of the subjects with ADHD symptoms, 17% showed externalizing symptoms (ODD or CD), and 12.6% showed both. Comorbid symptoms were 10 times more frequent than in subjects without ADHD symptoms. Inattentive subtype and scholastic impairment were more frequent in females, Hyperactive/Impulsive subtype and social impairment were more frequent in males. CONCLUSIONS: Even though the real prevalence of ADHD in first graders is presumably lower than that found in the present study, this screening procedure might allow detecting those children who could benefit from referral for more comprehensive assessments.
