Comorbidity between obesity and attention deficit/hyperactivity disorder: Population study with 13–15-year-olds

Objective: This study analyzes whether obese children have a higher risk of attention deficit/hyperactivity “characteristics” (AD/HD) than do children with other nutritional states. Method: This study included 35,403 participants from 486 community schools. They completed the AD/HD scale of the Strengths and Difficulties Questionnaire (SDQ) and were weighed and measured. 2879 of the participants were obese and 78 were morbidly obese (BMI >40). Results: A discrete, nonsignificant, increment was found in the AD/HD characteristics of male participants with morbid obesity, as compared with the other nutritional states. Among morbidly obese females, the prevalence of AD/HD characteristics was sl…

The effects of reward and frustration in patients with bipolar disorder: Evidence from a computerized task with non-contingent feedback.

Abstract Background: Bipolar disorder (BD) is characterized by mood changes that implies alterations in reward sensitivity and frustration tolerance. This study examined the effects of monetary reward and frustration on attentional performance and on affective experience across mood states in BD. Methods: An Affective Posner Task in which the nature of contingencies are divided in the three successive blocks (baseline condition, monetary reward and non-contingent feedback) was applied to BD individuals in their different episodes: mania (n = 30), depression (n = 30), and euthymia (n =  30) as well as to a group of healthy controls (n = 30). Results: Monetary reward improved performance (in …

Is processing speed a valid neurocognitive endophenotype in bipolar disorder? Evidence from a longitudinal, family study.

[Background] Substantial evidence supports the existence of neurocognitive endophenotypes in bipolar disorder (BD), but very few longitudinal studies have included unaffected relatives. In a 5-year, follow-up, family study, we have recently suggested that deficits in manual motor speed and visual memory could be endophenotype candidates for BD. We aimed to explore whether this also applies to processing speed.

Attentional biases toward emotional images in the different episodes of bipolar disorder: an eye-tracking study.

Attentional biases toward emotional information may represent vulnerability and maintenance factors in bipolar disorder (BD). The present experimental study examined the processing of emotional information in BD patients using the eye-tracking technology. Bipolar patients in their different states (euthymia, mania, depression) simultaneously viewed four pictures with different emotional valence (happy, neutral, sad, threatening) for 20 s while their eye movements were monitored. A group of healthy individuals served as the control. The data revealed the following: (i) a decrease in attention to happy images in BD patients in their depressive episodes compared to healthy individuals, and (ii…

Impulsivity, sensation seeking and aggressiveness in patients with bipolar I and II disorder

Abstract Objective Although impulsivity may seem to be strongly linked to bipolar disorder, few studies have directly measured this phenomenon. To determine its implications for the prognosis of this illness, we studied the relationship between impulsivity and other aspects that are probably related, such as sensation seeking and aggressiveness, and different clinical variables of bipolar disorder. Method Sixty-nine (type I, n = 42; type II, n = 27) outpatients from a unit specifically for bipolar patients in remission completed the Barratt Impulsiveness Scale (BIS), the Sensation Seeking Scale (SSS), the Buss–Durkee Hostility Inventory (BDHI) and the Bipolar Eating Disorder Scale (BEDS).

Are affective temperaments determinants of quality of life in euthymic patients with bipolar disorder?

Background: Bipolar disorder (BD) is a disabling illness that is associated with low quality of life (QoL). This low QoL goes further than mood episodes, which suggests that stable traits, such as affective temperaments, can cause functional impairment. Objective: Our study analyses the impact of affective temperaments on the Physical Component Summary (PCS) and Mental Component Summary (MCS) of QoL in euthymic BD patients. Methods: A multicentre study was conducted in 180 euthymic BD patients and 95 healthy controls. Firstly, statistical analyses were performed to compare QoL and affective temperaments between the two groups. Secondly, Adaptive Lasso Analysis was carried out to identify th…

Teasing and Disordered Eating Behaviors in Spanish Adolescents

The purpose of this study is to investigate the associations between peer teasing and body dissatisfaction (BD), emotional symptoms, drive for thinness (DT), and abnormal eating behaviors, as well as to analyze the mediating role of gender and body mass index (BMI) in such disorders. We screened 57,997 school children between 13 and 16 years of age. Scores in weight-related teasing and competency-related teasing were higher among girls, as well as overweight or obese individuals. Weight-teasing correlated more strongly with abnormal eating attitudes and behaviors, whereas competency-teasing correlated with emotional symptoms. Multiple linear regression analysis showed that weight-teasing is…

Mood-congruent bias and attention shifts in the different episodes of bipolar disorder

An "affective" go/no-go task was used in the different episodes of bipolar patients (euthymic, depressed, and manic) to examine (1) the presence of a mood-congruent attentional bias; and (2) the patients' ability to inhibit and invert associations between stimuli and responses through blocks. A group of healthy individuals served as controls. Results revealed a mood-congruent attentional bias: patients in the manic episode processed positive information faster, whereas those in the depressive episode processed negative information faster. In contrast, neither euthymic patients nor healthy individuals showed any mood-congruent biases. Furthermore, there was a shift cost across blocks for hea…

The effect of concomitant benzodiazepine use on neurocognition in stable, long-term patients with bipolar disorder

Objective: Neurocognitive dysfunction is a common feature of bipolar disorder even in euthymia, and psychopharmacological treatment could have an effect on cognition. Long-term prescription of benzodiazepines in bipolar disorder is a common practice, and their effect on neurocognition has not been well studied in this population. The aim of this study was to evaluate the impact of concomitant benzodiazepine long-term use on neurocognitive function in stable euthymic bipolar disorder patients. Methods: Seventy-three euthymic bipolar disorder outpatients and 40 healthy individuals were assessed using a neurocognitive battery. Patients were classified in two groups according to the presence of…

Abnormal emotional processing in maltreated children diagnosed of Complex Posttraumatic Stress Disorder.

Abstract Maltreated children usually show a specific pattern of emotional and behavioral symptoms that exceed those relating to posttraumatic stress disorder (PTSD). These symptoms have been defined as Complex PTSD (CPTSD). The underlying attentional mechanisms of abnormal emotional processing and their relation to the clinical presentation of CPTSD are not well understood. A visual dot-probe paradigm involving pre-attentive (i.e., 500 ms) and attentive (i.e., 1500 ms) presentation rates of neutral versus emotional (i.e., angry, happy or sad) facial expressions was applied. Twenty-one maltreated CPTSD children were compared with twenty-six controls. The results are as follows: an attention …

Do affective episodes modulate moral judgment in individuals with bipolar disorder?

Abstract Background Bipolar disorder (BD) patients experience altered emotional states and deficits in social adaptation that may also be involved in deontological moral judgments in which participants have to choose whether to sacrifice one person in order to save the lives of a greater number. Methods In the present study we compared the utilitarian responses of BD patients in their different states (euthymia, mania, depression) and healthy controls to moral dilemmas with low (impersonal dilemma) and high (personal dilemma) emotional saliency. Results Our findings revealed an increased tendency to utilitarian judgments in the three groups of BD patients in impersonal dilemmas relative to …

Neurocognitive endophenotypes in schizophrenia and bipolar disorder: A systematic review of longitudinal family studies

Although there is substantial evidence supporting the existence of neurocognitive impairment in patients diagnosed with schizophrenia (SZ) and bipolar disorder (BD), few studies have explored the field from an endophenotypic perspective. The present systematic review sought to identify longitudinal family studies exploring suitable neurocognitive endophenotypes in unaffected relatives of patients with SZ and/or BD. Following the PRISMA statement, only five follow-up studies met the inclusion criteria, comprising 79 SZ patients, 159 SZ unaffected relatives of SZ, 131 BD patients, 77 unaffected relatives of BD, and 248 controls. Verbal memory, auditory attention, face memory and emotion proce…

Prevalence and comorbidity of eating disorders among a community sample of adolescents: 2-year follow-up

The previous literature about comorbidity between eating disorders (ED) and other DSM-IV psychiatric disorders in adolescence has employed cross-sectional studies with clinical samples, where the comorbid disorders were diagnosed retrospectively. The present study aims to overcome these limitations by the analysis of comorbidity in a community population during 2-year follow-up. A semi-structured interview was applied to a teenager sample. Firstly, a cross-sectional and nonrandomized study on psychiatric morbidity was conducted with 993 teenagers between the ages of 12 and 16 from five schools. Secondly, 326 students between 14 and 17 years old of one school were reassessed 2 years later in…

Sexual Dysfunction and Mood Stabilizers in Long-Term Stable Patients With Bipolar Disorder.

Abstract Background In addition to factors intrinsic to bipolar disorder (BD), sexual functioning (SF) can be affected by extrinsic causes, such as psychotropic drugs. However, the effect of mood stabilizers on SF and quality of life (QoL) is an underexplored research area. Aim To analyze SF in BD outpatients in euthymia for at least 6 months treated only with mood stabilizers and the association between SF and QoL. Methods A multicenter cross-sectional study was conducted in 114 BD outpatients treated with (i) lithium alone (L group); (ii) anticonvulsants alone (valproate or lamotrigine; A group); (iii) lithium plus anticonvulsants (L+A group); or (iv) lithium plus benzodiazepines (L+B gro…
