Cocaine abuse, attention deficit disorder, and bipolar disorder.

Cocaine is a potent dopamine agonist that frequently stimulates the central nervous system and is often manifested by increased psychomotor activity, impulsivity, euphoria, and rapid thoughts. Attention deficit disorder (ADD) and bipolar disorder also present with physical restlessness, racing thoughts, distractibility, and mood instability. Although these three disorders rarely appear in the same individual, they are important differential diagnoses when considering any one illness with the above symptom complexes. We report two cases of cocaine abuse with ADD residual type in patients who were previously diagnosed as having atypical bipolar disorder. The adverse effects were reversed by the dopamine agonist bromocriptine.

Psychopathology in the adolescent and young adult offspring of parents with dysthymic disorder and major depressive disorder.

This study addressed the following question: are the adolescent and young adult offspring of parents with early-onset dysthymic disorder (DD) at increased risk for psychopathology? Participants included 41 offspring of 21 outpatients with early-onset DD, 19 offspring of nine outpatients with episodic major depressive disorder (MDD), and 32 offspring of 11 normal controls (NCs). Lifetime best-estimate diagnoses were determined for each offspring using a team consensus method. Diagnoses were derived blind to all information about the index parents. The offspring of outpatients with early-onset DD exhibited significantly higher lifetime rates of a broad range of psychiatric disorders than the offspring of NCs. In addition, the offspring of outpatients with early-onset DD exhibited significantly higher lifetime rates of DD, anxiety disorders, and phobia than the offspring of outpatients with episodic MDD. These results support the importance of early-onset DD in parents as a risk factor for psychopathology in their offspring.

Erythrocyte sodium pump activity in bipolar affective disorder and other psychiatric disorders.

Erythrocyte ouabain-inhibitable sodium pump activity, a measure of NaK-ATPase activity, was studied in 6 diagnostic groups of psychiatric subjects: bipolar affective disorder, unipolar depressive disorder, neurotic depression, chronic alcohol abuse, schizoaffective disorder, and schizophrenia, and in sex- and age-matched normal controls. In the bipolar manic-depressive group, which was restricted to lithium-free subjects, values for sodium pump activity were significantly lower than in the controls (-11.4%, n = 53, p less than 0.001); subgrouping of the bipolar group by sex or age showed a significantly lower sodium pump activity in each of the groups. In the unipolar depressive group, values for sodium pump activity were significantly higher than in the controls (+13.7%, n = 12, p less than 0.01). The difference in direction of changed sodium pump activity between the bipolar and the unipolar groups was also observed in the values for subgroups of subjects in the two categories who were in a depressed state at the time the blood sample was taken. In the chronic alcohol abuse group, values for sodium pump activity were significantly higher than those for the control group (+13.5%, n = 20, p less than 0.05). In the neurotic depression (n = 24), schizoaffective (n = 12), and schizophrenia (n = 35) groups, there were no significant differences in sodium pump activity between the group of psychiatric subjects and their matched controls. These observations indicate that there is a trait-dependent deficiency of NaK-ATPase activity in bipolar affective disorder.

Trauma and posttraumatic stress disorder in subjects with anxiety disorders.

Trauma histories were obtained from 711 subjects in a large study of anxiety disorders, with the intent of determining the prevalence and nature of psychological trauma in this group. Twenty-seven percent of subjects reported significant trauma; 35% of these (10% of all subjects) met DSM-II-R criteria for posttraumatic stress disorder (PTSD). Subjects reporting sexual trauma were significantly more likely to have PTSD. The rate of PTSD was not higher in subjects with panic disorder than in those with other anxiety disorders.

Epidemiologic studies of trauma, posttraumatic stress disorder, and other psychiatric disorders.

This paper reviews recent epidemiologic studies of posttraumatic stress disorder (PTSD) in the general population. Estimates of the prevalence of exposure to traumatic events vary with the method used to ascertain trauma exposure and the definition of the stressor criterion. Changes in the DSM-IV definition of "stressor" have increased the number of traumatic events experienced in the community that can be used to diagnose PTSD and thus, the number of PTSD cases. Risk factors for PTSD in adults vary across studies. The 3 factors identified as having relatively uniform effects are 1) preexisting psychiatric disorders, 2) a family history of disorders, and 3) childhood trauma. In civilian populations, women are at a higher risk for PTSD than are men, following exposure to traumatic events. Most community residents have experienced 1 or more PTSD-level traumas in their lifetime, but only a few succumb to PTSD. Trauma victims who do not succumb to PTSD are not at an elevated risk for the subsequent onset of major depression or substance use disorders, compared with unexposed persons.

Heritability and the comorbidity of attention deficit hyperactivity disorder with behavioral disorders and executive function deficits: a preliminary investigation.

The heritability and comorbidity of attention deficit hyperactivity disorder (ADHD) with conduct disorder (CD), oppositional defiant disorder (ODD), and executive function (EF) deficits were examined in 224 child twins (140 monozygotic and 84 dizygotic). The Coolidge Personality and Neuropsychological Inventory for Children (Coolidge, 1998), a standardized, 200-item, Diagnostic and Statistical Manual of Mental Disorders (4th ed.; American Psychiatric Association, 1994) aligned, parent-as-respondent inventory, assessed psychopathology. Structural equation model fitting revealed that the individual scale heritabilities were substantial: .82 for ADHD, .74 for CD, .61 for ODD, and .77 for EF deficits. The results of the multivariate twin analyses suggest that ADHD shares most of its genetic liability with CD, ODD, and EF deficits. Thus, the findings argue for a common biological risk underlying these commonly comorbid externalizing behavior problems and cognitive deficits. The residual genetic variance provides preliminary support for additional genetic influences underlying CD, ODD, and EF that are independent of ADHD.

Family psychiatric histories in male patients with generalized anxiety disorder and major depressive disorder.

It has been hypothesized, from twin study results in females, that the genetic predisposition in females for major depressive disorder (MDD) and generalized anxiety disorder (GAD) is identical. This report attempted to replicate these findings on a male population using family history methods. There were 119 subjects who completed standardized assessment of Axis I, Axis II, and family history. The family history of four groups was compared--GAD without MDD, MDD without GAD, GAD/MDD, and normals. As expected, GAD and MDD subjects showed trends toward more MDD family history than normals. The GAD and MDD groups showed only trend differences in family history of relatives. Unexpectedly, however, the MDD/GAD group had no higher level of either anxiety or depressive family history than normals (although they did have higher levels of personality family history). Both the GAD and the MDD groups had a significantly higher level of family history of depression than the GAD/MDD group. Within the limits of the family history method, the finding of similarity of the family predisposition of MDD and GAD was confirmed in a male population. However, it does appear that the combined disorder of MDD/GAD in clinical settings might have very different family history predispositions and possibly could be a separate disorder from both MDD and GAD when they are not comorbid.

World Federation of Societies of Biological Psychiatry (WFSBP) Guidelines for Biological Treatment of Unipolar Depressive Disorders, Part 1: Acute and continuation treatment of major depressive disorder.

These practice guidelines for the biological treatment of unipolar depressive disorders were developed by an international Task Force of the World Federation of Societies of Biological Psychiatry (WFSBP). The goal for developing these guidelines was to systematically review all available evidence pertaining to the treatment of unipolar depressive disorders, and to produce a series of practice recommendations that are clinically and scientifically meaningful based on the available evidence. These guidelines are intended for use by all physicians seeing and treating patients with these conditions. The data used for developing these guidelines have been extracted primarily from various national treatment guidelines and panels for depressive disorders, as well as from meta-analyses and reviews on the efficacy of antidepressant medications and other biological treatment interventions identified by a search of the MEDLINE database and Cochrane Library. The identified literature was evaluated with respect to the strength of evidence for its efficacy and was then categorized into four levels of evidence (A-D). This first part of the guidelines covers disease definition, classification, epidemiology and course of unipolar depressive disorders, as well as the management of the acute and continuation-phase treatment. These guidelines are primarily concerned with the biological treatment (including antidepressants, other psychopharmacological and hormonal medications, electroconvulsive therapy, light therapy, adjunctive and novel therapeutic strategies) of young adults and also, albeit to a lesser extent, children, adolescents and older adults.

Validation of the Mood Disorder Questionnaire for bipolar disorders in adolescents.

OBJECTIVE: The study was designed to determine the validity of the Mood Disorder Questionnaire-Adolescent Version (MDQ-A) as a screening instrument for bipolar disorders (I, II, not otherwise specified, and cyclothymia) in an adolescent outpatient psychiatric population. METHOD: 104 adolescents and their parents completed the MDQ-A. Three versions of the MDQ-A were compared: (1) self report of symptoms by adolescent, (2) attributional report-how the adolescent believed teachers or friends would report his/her symptoms, and (3) parent report of adolescent's symptoms. DSM-IV diagnosis was made based upon the clinician-administered Schedule for Affective Disorders and Schizophrenia for School-Age Children-Present and Lifetime Version (K-SADS-PL), a semistructured diagnostic interview. MDQ-A items were summed, yielding a score for each adolescent ranging from 0 to 13 on each of the 3 MDQ-A versions. Each possible scoring threshold, in combination with co-occurrence of symptoms and behaviors and with moderate to serious problems caused by symptoms, was crossed with the results of the K-SADS-PL diagnostic interview to assess sensitivity and specificity. The study was conducted from April 2002 to September 2003. RESULTS: A score of 5 or more items on the parent version yielded a sensitivity of 0.72 and specificity of 0.81, which were superior to self and attributional versions. CONCLUSIONS: The MDQ-A completed by parents about their adolescents' symptoms may be a useful screening instrument for bipolar disorders in an adolescent psychiatric outpatient population.

[Sleeping disorders can imitate attention deficit/hyperactivity disorder].

Attention deficit/hyperactivity disorder (ADHD) is often associated with anxiety, depression, oppositional defiant disorder and sleeping difficulties. Sleeping disorders are reported in more than 50% of children with ADHD. On the other hand, symptoms of sleep disorder, inattention, hyperactivity and impulsiveness can imitate the symptoms of ADHD. We describe a 5(1/2)-year-old boy with symptoms of attention deficit and social withdrawal. His sleep was disturbed, with late sleep onset and frequent awakening during the night. After correction of his sleep pattern, the symptoms of attention deficit and social withdrawal disappeared.

The role of genetic factors in conduct disorder based on studies of Tourette syndrome and attention-deficit hyperactivity disorder probands and their relatives.

To examine the role of genetic factors in oppositional defiant disorder (ODD) and conduct disorder (CD), 38 variables relating to the relevant DSM-III-R criteria, as well as other angry and aggressive behaviors, were examined in 1177 Tourette syndrome (TS) and attention-deficit hyperactivity disorder (ADHD) probands, their first-degree relatives, and controls. Two techniques were used: (1) a genetic loading technique comparing the frequency of symptoms in groups with progressively less genetic loading for Gts and ADHD genes, and (2) comparison of the frequency of symptoms in relatives with, versus relatives without, TS or ADHD. When significant, the latter rules out ascertainment bias and inappropriate controls. For TS, the results were significant with most p values less than 10(-8). The same trends were seen in the smaller number of ADHD families. A polygenic model is proposed in which TS and ADHD alone represent lesser degrees of genetic loading and expression, and TS + CD not equal to ADHD represents a higher degree of genetic loading and expression of genes common to all three disorders. These studies emphasize the important role of genetic factors in ODD and CD. The therapeutic implications are discussed.

Factor analysis of symptom subtypes of obsessive compulsive disorder and their relation to personality and tic disorders.

Despite advances in our understanding of the pathology and genetics of obsessive compulsive disorder (OCD) and in our ability to successfully treat patients with medications and behavioral psychotherapy, the identification of homogeneous subgroups of patients with OCD has remained elusive. Once identified, such subgroups may be found related to treatment response, biological markers, or genetic transmission of OCD. To clarify identification of symptom subtypes, my colleagues and I administered the Yale-Brown Obsessive Compulsive Scale (Y-BOCS) Symptom Checklist to 107 patients with OCD and applied principal components analysis (e.g., factor analysis) to these data. We then examined the correlations between these factor scores and the presence of comorbid tic and personality disorders, which are thought to be related to OCD. We found that three factors, which we named "symmetry/hoarding," "contamination/cleaning," and "pure obsessions," best explained the symptoms of the Y-BOCS Symptom Checklist. Only the first factor was significantly related to comorbid obsessive compulsive personality disorder or to a lifetime history of Tourette's syndrome or chronic tic disorder. Implications of these findings regarding possible clinical utility are discussed.

Patterns of personality disorders in women with chronic eating disorders.

The aim of this study was to describe patterns of personality disorders (PDs) in women with chronic eating disorders (EDs). An index group of nineteen women who have had EDs for an average of 8.5 years was compared with a control group of same-aged women from the general population. At the time of the study the index group received treatment at a tertiary treatment center in Stockholm. The PDs were assessed using the DSM-IV part of the DSM-IV and ICD-10 Personality Questionnaire (DIP-Q). In the index group, eighteen of nineteen fulfilled the criteria for one or more PD. The number of PD diagnoses for each women ranged from zero (n = 1) to eight (n = 2) with a median of three. Among the controls, only one woman fulfilled the criteria for one or more PD. The most prevalent disorders in the index group were Borderline, Avoidant, and Obsessive-Compulsive. The index group had significantly higher DIP-Q dimensional scores than the controls in the Paranoid, Schizoid, Schizotypal, Borderline, Histrionic, Avoidant, and Dependent scales. Although the assessment of PD symptoms was limited to self-reports, the high prevalence of PD diagnoses and PD symptoms most probably reflects the severe psychiatric impairments in patients suffering from chronic ED.

How do eating disorders and alcohol use disorder influence each other?

OBJECTIVE: Although eating disorders and alcohol use disorder (AUD) are known to co-occur, the influence of one on the other has not been studied. METHOD: In a prospective study, women diagnosed with either anorexia nervosa (AN; n = 136) or bulimia nervosa (BN; n = 110) were interviewed and assessed for Research Diagnostic Criteria (RDC) AUD every 6-12 months over 8.6 years. RESULTS: Over one fourth of the sample (n = 66 [27%]) reported a lifetime history of AUD. Ten percent of the study subjects (n = 24) developed AUD over the course of the study. AUD did not influence recovery from either eating disorder. Poor psychosocial functioning and history of substance use predicted prospective onset of an episode of AUD for both diagnostic groups. Unique predictors for AUD for women with AN were depression, overconcern with body image, and vomiting. Recovery from AUD was predicted by group therapy and hospitalization (women with AN) and individual therapy and exercise (women with BN). CONCLUSION: The influence of eating disorders on AUD appears to be greater than the reverse. A substantial number of patients who initially present with an eating disorder develop alcohol problems over the course of time, suggesting that the risk is an ongoing one that should be monitored by clinicians.

Assessment of body image in eating disorders with the body dysmorphic disorder examination.

The Body Dysmorphic Disorder Examination (BDDE) has several advantages for the assessment of body image in eating disorder patients. It measures distressing self-consciousness, preoccupation with appearance, overvalued ideas about the importance of appearance to one's self-worth, and body image avoidance and checking behaviors. The BDDE is relevant for any type of appearance complaint and is not limited to weight or body shape concerns. The BDDE measures the useful targets for body image therapy. In a sample of eating disorder patients, the Body Dysmorphic Disorder Exam had good internal consistency and was significantly correlated with other measures of body image. It added new information to the discrimination of women with eating disorders from clinical and nonclinical controls beyond that provided by other measures of body image.

Reproductive disorders in dairy cattle. II. Interrelationships between pre-or post-service infectious and functional disorders.

This retrospective study was aimed at investigating the interrelationships between the various post-partum reproductive disorders whose incidence distribution was reported in a previous paper. There were 343 calving cows, and 319 of them were inseminated at least once. Although approximately one-third of the cows suffered from metritis, its influence on subsequent pathology was only minor. No within-animal relationship could be found between post-partum cyclic anestrus and post-AI anestrus. The distribution of repeat breeding cows showed that almost half of them also had post-AI anestrus, and only 17% had no other disorders. Previous metritis accounted for only 10% of these cases. Embryonic mortality was related only to post-partum cyclic anestrus. Finally, it was found that approximately half of the cows suffered from more than one reproductive disorder with many different relations between the disorders within individuals during post partum. In conclusion, optimal efficiency of post-partum reproduction requires careful checking of all possible disorders.

Random activation energy model and disordered kinetics, from static to dynamic disorder.

We suggest a unified path integral approach for random rate processes with random energy barriers, which includes systems with static and dynamic disorder as particular cases. We assume that the random component of the activation energy barrier can be described by a generalized Zubarev-McLennan nonequilibrum statistical ensemble that can be derived from the maximum information entropy approach by assuming that the time history of the fluctuations of the random components of the energy barrier are known. We show that the average survival function, which is an experimental observable in disorderd kinetics, can be computed exactly in terms of the characteristic functional of this generalized Zubarev-McLennan nonequilibrium statistical ensemble. We investigate different types of disorder described by our approach, ranging from static disorder with infinite memory to random processes with long or short memory, and finally to rapidly fluctuating independent random processes with no memory. We derive expressions of the average survival function for all these types of disorder and discuss their implications in the evaluation of kinetic parameters from experimental data. We illustrate our approach by studying a simple model of dynamic disorder of the renewal type. Finally we discuss briefly the implications of our approach in molecular biology and genetics.
