Psychiatric and developmental disorders in families of children with attention-deficit hyperactivity disorder.

OBJECTIVE: To evaluate whether a pediatric family history obtained via a brief parent interview would reveal a high prevalence of psychiatric and developmental disorders in the family members of children with attention-deficit hyperactivity disorder (ADHD) compared with a group of children with another chronic developmental disability, Down syndrome (DS). DESIGN: A controlled cross-sectional group comparison study. SETTING: An interdisciplinary hyperactivity and learning problem clinic and a DS clinic located in a large, urban tertiary care teaching hospital in Chicago, Ill. PARTICIPANTS: A total of 140 children with ADHD and 163 children with DS of comparable socioeconomic status. MEASURES: Using a screening questionnaire and parent interview, the development pediatricians obtained a family history. RESULTS: By parent report, children with ADHD were significantly more likely than the control children with DS to have a parent affected by alcoholism (P = .007), other drug abuse (P < .001), depression (P < .001), delinquency (P < .001), learning disabilities (P < .001), and ADHD (P < .001). Similar patterns were evidenced in other first- and second-degree relatives. CONCLUSIONS: The high reported frequency of psychiatric and developmental disorders in the families of children with ADHD requires that the treating clinician explore the area of family psychiatric and developmental history and use the findings to formulate a comprehensive treatment plan that includes anticipatory guidance and psychosocial intervention.

Effects of one night's sleep deprivation on mood and behavior in panic disorder. Patients with panic disorder compared with depressed patients and normal controls.

The effects of one night's sleep deprivation on mood and behavior were evaluated in 12 patients with panic disorder, ten depressed patients, and ten controls. In contrast to the improvement in symptoms of anxiety and depression shown by the majority of depressed patients, the response of patients with panic disorder as a group did not differ from that of normal controls, although a subgroup did experience noticeable worsening in their symptoms of anxiety, with 40% experiencing panic attacks on the day following sleep deprivation. Electroencephalographic recordings with nasopharyngeal electrodes on the day following sleep deprivation were normal, further suggesting that patients with panic disorder do not have seizure activity characteristic of temporal lobe epilepsy.

Individual growth curve analysis illuminates stability and change in personality disorder features: the longitudinal study of personality disorders.

BACKGROUND: The long-term stability of personality pathology remains an open question. Its resolution will come from prospective, multiwave longitudinal studies using blinded assessments of personality disorders (PD). Informative analysis of multiwave data requires the application of statistical procedures, such as individual growth curve modeling, that can detect and describe individual change appropriately over time. The Longitudinal Study of Personality Disorders, which meets contemporary methodological design criteria, provides the data for this investigation of PD stability and change from an individual growth curve perspective. METHODS: Two hundred fifty subjects were examined for PD features at 3 different time points using the International Personality Disorders Examination during a 4-year study. Stability and change in PD features over time were examined using individual growth modeling. RESULTS: Fitting of unconditional growth models indicated that statistically significant variation in PD features existed across time in the elevation and rate of change of the individual PD growth trajectories. Fitting of additional conditional growth models, in which the individual elevation and rate-of-change growth parameters were predicted by subjects' study group membership (no PD vs possible PD), sex, and age at entry into the study, showed that study group membership predicted the elevation and rate of change of the individual growth curves. Comorbid Axis I psychopathology and treatment during the study period were related to elevations of the individual growth trajectories, but not to rates of change. CONCLUSIONS: From the perspective of individual growth curve analysis, PD features show considerable variability across individuals over time. This fine-grained analysis of individual growth trajectories provides compelling evidence of change in PD features over time and does not support the assumption that PD features are traitlike, enduring, and stable over time.

The Yale-Brown-Cornell Eating Disorder Scale: a new scale to assess eating disorder symptomatology.

Anorectic and bulimic patients (n = 100) were interviewed using the Yale-Brown-Cornell Eating Disorder Scale (YBC-EDS). All patients reported preoccupations and rituals related to their eating disorder ranging from mild to severe symptomatology, with mean scores in the moderate range. The preoccupations were more severe than the rituals; however, the rituals were still time-consuming, distressing, and interfered with functioning. Both preoccupations and rituals were largely ego syntonic. The YBC-EDS is an easy to administer interview which characterizes and quantifies preoccupations and rituals associated with eating disorders. It is useful both for research and clinical purposes.

Targeted genome screen of panic disorder and anxiety disorder proneness using homology to murine QTL regions.

Family and twin studies have indicated that genes influence susceptibility to panic and phobic anxiety disorders, but the location of the genes involved remains unknown. Animal models can simplify gene-mapping efforts by overcoming problems that complicate human pedigree studies including genetic heterogeneity and high phenocopy rates. Homology between rodent and human genomes can be exploited to map human genes underlying complex traits. We used regions identified by quantitative trait locus (QTL)-mapping of anxiety phenotypes in mice to guide a linkage analysis of a large multiplex pedigree (99 members, 75 genotyped) segregating panic disorder/agoraphobia. Two phenotypes were studied: panic disorder/agoraphobia and a phenotype ("D-type") designed to capture early-onset susceptibility to anxiety disorders. A total of 99 markers across 11 chromosomal regions were typed. Parametric lod score analysis provided suggestive evidence of linkage (lod = 2.38) to a locus on chromosome 10q under a dominant model with reduced penetrance for the anxiety-proneness (D-type) phenotype. Nonparametric (NPL) analysis provided evidence of linkage for panic disorder/agoraphobia to a locus on chromosome 12q13 (NPL = 4.96, P = 0.006). Modest evidence of linkage by NPL analysis was also found for the D-type phenotype to a region of chromosome 1q (peak NPL = 2.05, P = 0.035). While these linkage results are merely suggestive, this study illustrates the potential advantages of using mouse gene-mapping results and exploring alternative phenotype definitions in linkage studies of anxiety disorder.

Mutation screen of the brain derived neurotrophic factor gene (BDNF): identification of several genetic variants and association studies in patients with obesity, eating disorders, and attention-deficit/hyperactivity disorder.

Several lines of evidence indicate an involvement of brain derived neurotrophic factor (BDNF) in body weight regulation and activity: heterozygous Bdnf knockout mice (Bdnf(+/-)) are hyperphagic, obese, and hyperactive; furthermore, central infusion of BDNF leads to severe, dose-dependent appetite suppression and weight loss in rats. We searched for the role of BDNF variants in obesity, eating disorders, and attention-deficit/hyperactivity disorder (ADHD). A mutation screen (SSCP and DHPLC) of the translated region of BDNF in 183 extremely obese children and adolescents and 187 underweight students was performed. Additionally, we genotyped two common polymorphisms (rs6265: p.V66M; c.-46C > T) in 118 patients with anorexia nervosa, 80 patients with bulimia nervosa, 88 patients with ADHD, and 96 normal weight controls. Three rare variants (c.5C > T: p.T2I; c.273G > A; c.*137A > G) and the known polymorphism (p.V66M) were identified. A role of the I2 allele in the etiology of obesity cannot be excluded. We found no association between p.V66M or the additionally genotyped variant c.-46C > T and obesity, ADHD or eating disorders.

Posttraumatic stress disorder in callers to the Anxiety Disorders Association of America.

We surveyed callers to the Anxiety Disorders Association of America (ADAA) with posttraumatic stress disorder (PTSD) and subthreshold PTSD (SPTSD). Most subjects heard about ADAA through media referrals and were satisfied with the service given by the association. The most frequent requests were for written information, learning how to cope with anxiety, and access to a local support group. Among callers, rates of PTSD (n=80) and SPTSD (n=111) were 8.0% and 11.1%, respectively. PTSD or SPTSD subjects were more likely to be younger, female, and with lower income than their no-Axis I psychiatric disorder controls (NAC) who had been exposed to trauma. In addition, they presented with more history of trauma, especially violent trauma, psychiatric comorbidity, recent psychotropic use, and side effects. More medical comorbidity, increased health service use, and reduced work productivity were also found among the PTSD and SPTSD subjects. SPTSD subjects were comparable to PTSD subjects on most of the measures with a few exceptions (more likely to be married, to have less psychiatric comorbidity, less medication use for mood and social fear, and fewer sedation and sexual side effects, and to have less health service use and work impairment). In conclusion, callers to ADAA with PTSD were particularly impaired and used the health care system extensively. Although the SPTSD subjects were not as impaired as those with PTSD, they were disadvantaged in many ways.

Comorbidity between eating disorders and anxiety disorders: a review.

OBJECTIVE: We conducted a critical literature review on studies assessing the prevalence of anxiety disorders (AD) in subjects with eating disorders (ED) (anorexia nervosa and bulimia nervosa). In the first part, we discuss methodological issues relevant to comorbidity studies between ED and AD. In the second part, taking into account these methodological considerations raised, we summarize the findings of these studies. METHOD: We performed a manual and computerized search (Medline) for all published studies on comorbidity between ED and AD, limiting our search from 1985-2001 to get sufficiently homogeneous diagnostic criteria for both categories of disorders. RESULTS: Too few studies include control groups and few studies have compared diagnostic subgroups of ED subjects, with scarce or conflicting results. DISCUSSION: We discuss the results taking into account the methodological problems observed. We give guidelines for reviewing the results of published studies and planing future research.

Eating disorders symptomatology and inpatient treatment experience in eating-disordered subjects.

OBJECTIVE: This study aimed to examine whether eating disorder (ED) subjects with and without a history of inpatient treatment differ in the severity of symptoms as measured by the Eating Disorders Inventory (EDI-1). METHOD: In a sample of 222 women (66 women with anorexia nervosa, 126 women with bulimia nervosa, and 30 women with eating disorders not otherwise specified), the history of inpatient treatment was assessed and the EDI was administered. RESULTS: Fifty percent of the participants had received previous inpatient treatment. The group with past inpatient treatment had significantly higher scores on the EDI subscales Body Dissatisfaction, Ineffectiveness, and Interpersonal Distrust than the group without inpatient treatment experience. DISCUSSION: ED subjects with and without inpatient treatment showed different profiles on the EDI subscales. The fact that these two groups differ in specific ED symptoms may represent a bias in ED studies when samples with heterogeneous treatment contact history are recruited.

Juvenile conduct disorder as a risk factor for trauma exposure and posttraumatic stress disorder.

Juvenile conduct disorder (CD) is a well-documented risk factor for posttraumatic stress disorder (PTSD). This study examines the mechanisms underlying this relationship by using data from 3,315 twin pairs in the Vietnam Era Twin Registry. Results indicate the number of conduct disorder symptoms increased risk of trauma exposure and PTSD in a dose-response fashion. This increased risk was mediated in part by the positive association between CD and lifestyle factors and was not due to confounding by shared genetic or familial vulnerability. The findings suggest CD increases risk for trauma exposure and PTSD among male veterans through direct and indirect mechanisms. Veterans who have a history of CD are at high risk for trauma exposure and development of PTSD.

[Psychoreactive disorders after motor vehicle accidents. Is it possible to predict the development of psychoreactive disorders after motor vehicle accidents?].

The aim of this study was to assess common risk factors for the early development of psychoreactive disorders during traumatological treatment and to estimate their predictive potential. The sample consisted of 126 consecutive patients with accidental injuries recruited in an emergency room of the university hospital. We assessed this population 1 week (T1) and-on average-8 months following the accident (T2). At T1 34.5% of all patients indicated moderate and 26.4% strong symptoms of an acute stress disorder; 26.7% of all patients assessed at T2 suffered from severe post-traumatic symptoms. Linear regression analysis, using morbidity status at T2 as the dependent variable, allowed the explanation of 46.2% of the variance. The degree of early acute stress symptoms, injury, and pain intensity contributed significantly to the predictive model. We conclude that a substantial proportion of severely injured accident victims that will develop PTSD can be screened to some degree by the assessment of early stress disorder, the degree of their injury, and pain intensity, enabling secondary prevention of trauma-dependent symptomatology.

[Personality, accentuated traits and personality disorders. A contribution to dimensional diagnosis of personality disorders].

A dimensional diagnostic system for personality disorders (PD) postulates continuous transition from normal to disordered personalities (continuity hypothesis) and universal validity of basic personality dimensions (universal hypothesis). The present study investigates the validity of Leonhard's concept of attenuated personalities that define a conceptual link between normal personality dimensions and PD. Nine possible continuous transitions between three conceptual levels (Big Five personality factors, nine attenuated personality traits, nine PD) were tested by questionnaire data obtained from a mentally healthy (n = 166) and a clinical sample (n = 78). Both samples differed significantly in nearly all variables. However, they showed substantial similarity concerning the (in)validity of single continua and the complex structure of all variables as analyzed by multidimensional scaling. The concept of attenuated personalities could be validated for six out of nine tested continua and can be recommended for application in dimensional models of personality and personality disorders.

Total serum cholesterol level, violent criminal offences, suicidal behavior, mortality and the appearance of conduct disorder in Finnish male criminal offenders with antisocial personality disorder.

Associations between low total serum cholesterol (TC) levels and antisocial personality disorder (ASPD), violent and suicidal behavior have been found. We investigated the associations between TC levels, violent and suicidal behavior, age of onset of the conduct disorder (CD) and the age of death among 250 Finnish male criminal offenders with ASPD. The CD had begun before the age of 10 two times more often in non-violent criminal offenders who had lower than median TC levels. The violent criminal offenders having lower than median TC levels were seven times more likely to die before the median age of death in the study material. The violent offenders having lower than median TC levels were eight times more likely to die of unnatural causes. The mean TC level of these male offenders with ASPD was lower than that of the general Finnish male population. Low TC levels are associated with childhood onset type of the CD, and premature and unnatural mortality among male offenders with ASPD. The TC level seems to be a peripheral marker with prognostic value among boys with conduct disorder and antisocial male offenders.

[Pain processing in patients with borderline personality disorder, fibromyalgia, and post-traumatic stress disorder].

The authors review relevant experimental studies on pain perception and processing in psychiatric disorders with traumatic stress as an etiological factor. In borderline personality disorder, post-traumatic stress disorder, and fibromyalgia neurophysiological and neuropsychological patterns of pain processing appear to be different. Experimental studies in borderline patients show a desensitization of pain thresholds whereas patients with fibromyalgia show an opposite pattern, which could be explained by a central augmentation of pain processing. Furthermore, the authors outline methods to assess pain perception (peripheral and central) and describe the neurobiological mechanisms of pain processing, particularly the distinction between the sensory-discriminative lateral system and the affective-motivational medial system. Finally, suggestions for further research and implications for therapy are proposed.

Treating anxiety disorders in children with high functioning autism spectrum disorders: a controlled trial.

A family-based, cognitive behavioural treatment for anxiety in 47 children with comorbid anxiety disorders and High Functioning Autism Spectrum Disorder (HFA) was evaluated. Treatment involved 12 weekly group sessions and was compared with a waiting list condition. Changes between pre- and post-treatment were examined using clinical interviews as well as child-, parent- and teacher-report measures. Following treatment, 71.4% of the treated participants no longer fulfilled diagnostic criteria for an anxiety disorder. Comparisons between the two conditions indicated significant reductions in anxiety symptoms as measured by self-report, parent report and teacher report. Discussion focuses on the implications for the use of cognitive behaviour therapy with HFA children, for theory of mind research and for further research on the treatment components.

Comparison of attachment styles in borderline personality disorder and obsessive-compulsive personality disorder.

The intense, unstable interpersonal relationships characteristic of patients with borderline personality disorder (BPD) are thought to represent insecure attachment. The Reciprocal Attachment Questionnaire was used to compare the attachment styles of patients with BPD to the styles of patients with a contrasting personality disorder, obsessive-compulsive personality disorder (OCPD). The results showed that patients with BPD were more likely to exhibit angry withdrawal and compulsive care-seeking attachment patterns. Patients with BPD also scored higher on the dimensions of lack of availability of the attachment figure, feared loss of the attachment figure, lack of use of the attachment figure, and separation protest. The findings may be relevant for understanding the core interpersonal psychopathology of BPD and for managing therapeutic relationships with these patients.

Recent research of relationships among eating disorders and personality disorders.

This review focuses on recent research examining the relationships among eating disorders (ED) and personality disorders (PD). Studies that have examined rates of PD in patients with ED and rates of ED in patients with PD have generally reported high rates of diagnostic co-occurrence, although the marked inconsistency and variability in rates across studies is striking. Methodologic limitations and conceptual problems make interpretation of the existing literature ambiguous. Overall, circumspect review suggests that anorexia nervosa may be associated with obsessional and perfectionistic forms of personality disturbances, bulimia nervosa with impulsive and unstable personality disturbances, and binge eating disorder with avoidant and anxious forms of personality disturbances. In terms of longitudinal associations, PD may be more closely associated with the course of general psychiatric or psychosocial functioning than with fluctuations in the course of ED. The significance (and more precise nature) of these associations, however, is unclear and will require sophisticated longitudinal studies to arrive at more definitive answers.

Secondary affective disorder in women with somatization disorder.

Of 60 women with somatization disorder (SD), 54 (90%) met DSM-III criteria for a major affective episode. This group with secondary affective disorder (SAD) was compared with 29 women who had primary affective disorder (PAD). SAD patients reported significantly more symptoms, more psychiatric admissions, more and longer episodes of depression; more had attempted suicide, and more had made multiple attempts. SAD patients had often been hospitalized and were likely to have been treated with lithium and a variety of antidepressants. Studying relatively homogeneous primary psychiatric diagnoses facilitates the identification of distinctions between SAD and PAD patients.
