Distribution of symptoms of conduct disorder and antisocial personality disorder in Turkey

BACKGROUND: A variety of conduct disorder (CD) symptoms are seen together as a symptom cluster. Among CD symptoms there are serious and stubborn antisocial behaviors: lying, swindling, running away from home/school, destructiveness, arson, kidnapping women, sexual abuse, and armed robbery. The objective of this study was to discover the relationship between CD and antisocial personality disorder (APD) and the distribution of the symptoms of these disorders. SAMPLING AND METHODS: The research sample consisted of 994 individuals between the ages of 18 and 65 years in Sivas province. Subjects were given the Diagnostic Interview Schedule-III-R (DIS-III-R) APD subscale. RESULTS: The lifetime prevalence for CD and APD was found to be 21.03 and 3.02%, respectively. In both disorders the percentage of men was higher than for women. The comorbidity of both disorders was found to be 14.35%. The most frequently seen CD symptom in normal society is 'lying', but in those with CD 'initiates a fight several times' is the most frequently seen symptom. In those with APD the most frequently seen symptom is 'truant from school several times'. CONCLUSIONS: Identifying risk factors in children could be an important step in preventing the progression of CD and APD.     

Adult social attachment disturbance is related to childhood maltreatment and current symptoms in borderline personality disorder

We characterized borderline personality disorder (BPD) along two fundamental dimensions of adult social attachment and evaluated attachment associations with childhood maltreatment and current symptoms using self-report measures in 40 outpatients with DSM-IV BPD. The BPD group had significantly greater dimensional attachment impairment and rate of fearful attachment type compared with a healthy control group. Among BPD subjects, dimensional attachment-anxiety was specifically associated with sexual abuse, whereas attachment-avoidance was associated with all five maltreatment types. The two attachment dimensions showed divergent associations with current interpersonal problems, impulsivity subtypes and mood symptoms. We conclude that (1) BPD is characterized by adult attachment disturbance; (2) these attachment problems are strongly related to childhood maltreatment, and to current interpersonal problems and clinical symptoms that are considered core features of BPD; and (3) the diverse problems of BPD patients may arise from two basic mechanisms, each tied to a different type of attachment disturbance, developmental history, and clinical outcome.

Disturbed structural connectivity is related to inattention and impulsivity in adult attention deficit hyperactivity disorder

Inattention and impulsivity are the most prominent clinical features of attention deficit hyperactivity disorder (ADHD) in adulthood. Structural and functional neuroimaging studies of subjects with ADHD have demonstrated abnormalities in several brain areas, including fronto‐striatal and fronto‐cerebellar networks. Mostly, these studies were based on volumetric measurements and have been conducted in children. We investigated white matter (WM) integrity and correlation with measures of attention and impulsivity in adult patients with ADHD adopting diffusion tensor imaging (DTI). N = 37 (21 males) never‐medicated adult patients with ADHD combined subtype and N = 34 (16 males) healthy controls were investigated. ADHD diagnosis (DSM‐IV) was assessed with clinical interviews and rating scales, subjects also underwent a large neuropsychological test battery including tests of attention and impulsivity. DTI was acquired, and group differences of fractional anisotropy (FA) and mean diffusivity (MD) as well as correlation analyses with measures of attentional performance and impulsivity were calculated using voxel‐based analyses. In adult patients with ADHD, we found reduced FA as well as higher MD bilaterally in orbitomedial prefrontal WM and in the right anterior cingulate bundle, while elevated FA was present bilaterally in temporal WM structures. Measures of attention were correlated with DTI parameters in the right superior longitudinal fasciculus, whereas measures of impulsivity were correlated with FA in right orbitofrontal fibre tracts. This is the first DTI study demonstrating disturbed structural connectivity of the frontal‐striatal circuitry in adult patients with ADHD. Moreover, a direct correlation between WM integrity and measures of attention and impulsivity is shown.     

A Comparison of adults with antisocial personality traits with and without childhood conduct disorder.

BACKGROUND: Antisocial personality disorder (ASPD) in DSM-IV is unique among personality disorder diagnoses in requiring the individual to satisfy a number of childhood criteria in addition to relevant traits exhibited in adulthood. We examined the validity of this childhood requirement. METHODS: Personality disordered individuals assessed using the International Personality Disorder Examination and exhibiting a sufficient number of adult antisocial traits to meet criterion A of DSM-IV were subdivided into those who exhibited antisocial traits in both adulthood and childhood and those who had such traits in adulthood only. The two groups were then compared on a number of historical, clinical, and self-report measures. RESULTS: Thirty individuals meeting both childhood and adult criteria (ASPD) were compared with 39 meeting adult antisocial criteria only (ASS). Few differences were found between the two groups on the measures examined, although those in the ASPD group appeared more severe and had higher anger scores on the STAXI-2 psychometric test. CONCLUSIONS: This failure to find clinically important differences between the two groups is in agreement with previous reports and needs to be taken into account in future revisions of ASPD in DSM.     

Self-reported childhood attention-deficit/hyperactivity disorder symptoms are not specific to the disorder

Objective

The present study examined the specificity of self-reported childhood attention-deficit/hyperactivity disorder (ADHD) symptoms using the Wender Utah Rating Scale (WURS) in young adults with (1) a previous diagnosis of ADHD, (2) comorbid ADHD and psychological symptoms or diagnoses, (3) psychological diagnoses or symptoms without comorbid ADHD, and (4) controls.

Method

One thousand four hundred thirty-one non-treatment-seeking individuals (508 males), aged 18 to 25 years, were assigned to 1 of 4 groups (psychological controls, controls, ADHD, ADHD comorbid), based on responses to psychological, demographic, and health history questionnaires completed as part of a larger study. Responses to the WURS were analyzed at the individual item and subtest levels for their specificity to ADHD using area under the curve analyses.

Results

The standard WURS cutoff score of 46 was neither sensitive nor specific to ADHD, with a high rate of false positives in psychological controls. Factor analyses supported a 5-factor model (conduct problems, impulsivity problems, mood difficulties, inattention/anxiety symptoms, poor academic functioning) that accounted for 62% of the total variance; these factors were used to generate factor-based WURS subscales. Three subscales (impulsivity, poor academic functioning, and inattention/anxiety symptoms) showed potential for discriminating ADHD from controls among females. No subscales showed adequate sensitivity or specificity for discriminating ADHD from psychological controls among the males.

Conclusions

Results provide further evidence that retrospective self-report of childhood ADHD symptoms is not specific to ADHD and highlight concerns about the reliance on self-report of childhood ADHD symptoms for diagnostic purposes. Results suggest consideration of specific types of symptoms, and sex differences might increase diagnostic use of self-reported childhood symptoms.     

Association analysis between dopamine receptor genes and bipolar affective disorder.

We have performed a case-control analysis of dopamine D2-like receptor (DRD2, DRD3 and DRD4) gene polymorphisms in 118 Han Chinese cases with bipolar affective disorder and 196 control subjects, and replication analysis in 157 English cases and 143 control subjects. We found association between a functional DRD2 promoter variant (P = 0.03 by allele) and the DRD2 taq1A polymorphism (P = 0.001 by allele) in Chinese bipolar disorder patients. However, this finding was not replicated in the Caucasian subjects, indicating that the significant association we observed in the Chinese population is a false positive finding. An alternative explanation is that these polymorphisms are risk factors in Chinese but not Caucasian populations, a hypothesis which seems unlikely in view of the similarity of the clinical characteristics of bipolar disorder in the two populations. We also report a novel, rare one-repeat variant of the DRD4 exon 3 VNTR repeat in Chinese populations, which appears to be absent in Caucasians and is not associated with disease.     

Disgust propensity and sensitivity in childhood anxiety and obsessive-compulsive disorder: Two constructs differentially related to obsessional content

The role of disgust in anxiety and related disorders has been extensively studied in adults, however its role in childhood psychopathology is in need of further investigation. The adult literature has suggested that two distinct sub-constructs within “disgust proneness” may differentially predict anxiety-related disorders. Namely, disgust propensity (DP) has been defined as the likelihood an individual will experience a disgust reaction, and disgust sensitivity (DS) as the degree to which an individual is distressed by their experience of disgust. The current study aimed to validate the Disgust Propensity and Sensitivity Scale-Revised (DPSS-R) in a sample of youth receiving intensive services for OCD and anxiety, examine the relationship between disgust sub-constructs and obsessional content in a sample of youth with OCD, and examine the relationship between disgust change and symptom severity at discharge. A confirmatory factor analysis supported a two-factor structure of the DPSS-R. DP was found to be uniquely predictive of contamination obsessions, and DS was found to be uniquely predictive of moral obsessions. Lastly, change in DP, but not DS, predicted overall change in OCD symptom severity. The present study provides a valid measure of DS and DP in youth with anxiety and related disorders, and suggests that subconstructs of disgust may serve as distinct risk factors for obsessional content in youth with OCD. Future research should examine the predictive validity of DP and DS longitudinally, as well as examine effective ways to more effectively target DP with exposure therapy.     

A retrospective population-based study on seizures related to childhood vaccination

Purpose: Cases of severe childhood epilepsies in temporal association with vaccination have great impact on the acceptance of vaccination programs by parents and health care providers. However, little is known about the type and frequency of seizures and epilepsy syndromes following vaccination. This study aims to describe the clinical features of children presenting with seizures after vaccination using a register‐based cohort. Methods: We surveyed the national German database of adverse events following immunization (AEFI) for reported seizures and epilepsies in children aged 0–6 years. All cases reported in 2006–2008 were analyzed retrospectively; available clinical information was reevaluated and classified by seizure type and epilepsy syndrome. Key Findings: In total, 328 cases reported between 2006 and 2008 were included. Data supportive of seizures or epilepsy were present in 247 (75.3%) of 328 patients with a mean interval between the vaccination and the epileptic event of 24 h and 7.5 days for inactivated and attenuated vaccines, respectively. Fifty‐one (15.5%) of 328 patients presented with syncope, hypotonic–hyporesponsive episodes, or other nonepileptic events. Information was insufficient for classification into epileptic versus nonepileptic events in 30 (11.3%) of 328 patients. For cases with confirmed seizures, febrile seizures were present in 121 (49%) of 247 cases, and 38 (15.4%) of 247 patients had single afebrile seizures. Status epilepticus was described in 21 (8.5%) of 247 patients. Thirty‐one (12.6%) of 247 patients presented with various pediatric epilepsy syndromes. Severe childhood epilepsies (Dravet syndrome, West syndrome, Lennox–Gastaut syndrome, or Doose syndrome) were diagnosed in 29 (11.7%) of 247 patients, with the vaccination‐associated event being the first documented seizure in 15 (51.7%) of 29 patients. Significance: Vaccination‐associated seizures present in the setting of various epilepsy syndromes, including severe childhood epilepsies in >10% of cases. Early diagnosis of the corresponding epilepsy syndromes and confirmation of an underlying etiology is important for treatment decisions, genetic counseling, and public health evaluation of vaccine safety.     

Structural equation modeling of repeated retrospective reports of childhood maltreatment

The present study examined errors of reporting, including unreliability and recall bias, in retrospective reports of childhood maltreatment. Data were gathered on retrospective reports of childhood sexual and physical abuse and current mental health in a birth cohort of over 980 participants studied at ages 18 and 21. A structural equation model was developed to estimate the contributions of test unreliability and recall bias to reporting variation. Retrospective abuse reports were of modest test–retest reliability (r_tt = 0.50 approximately). Recall bias accounted for <1% of report variance. As a consequence the observed correlations between maltreatment and mental health closely approximated the corresponding estimated true correlations. The results of the study suggested that, for this cohort, errors of measurement in reports of childhood maltreatment did not pose a significant threat to study validity.

Temperament and characteristics related to attention deficit/hyperactivity disorder symptoms

ObjectiveAdult attention deficit/hyperactivity disorder (ADHD) exhibits symptoms, such as attention deficit and impulsivity, that make it difficult for patients to manage social activities. In this study, we investigated the association of adult ADHD symptoms with temperament and character dimensions, taking into account possible sex interactions.MethodA total of 2917 (1462 males and 1455 females) college students completed the 140 5-point Likert items on the Temperament and Character Inventory-Revised Short version (TCI-RS) and the Attention Deficit/Hyperactivity Disorder Self-Rated Scale (ASRS). According to the ASRS score, subjects were classified into the control group, the inattentive ADHD symptom (IA) group, or the hyperactive/impulsive ADHD symptom (HI) group. Additionally, the scores of the four temperament dimensions and the three character dimensions were compared.ResultsIn the IA and HI groups, the NS and HA levels of the temperament dimension were high and the PS level was low compared with the control group. In the character dimension, the levels of SD and CO were significantly lower in the ADHD groups than in the control group (P < 0.001). Meanwhile, the ST level in the HI group was significantly higher than in the control group. In the regression analysis after age and gender correction, NS and SD in the IA group and NS, CO, and ST in the HI group were associated with adult ADHD symptoms.ConclusionThe current findings suggest that high novelty seeking may be related to adult ADHD symptoms in the temperament dimension. Furthermore, some character dimensions were associated with adult ADHD symptoms.
