Impulsivity, sensation seeking and aggressiveness in patients with bipolar I and II disorder
2011
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). S…
Neuropsychological correlates of emotional lability in children with ADHD
2012
Background: Emotional lability (EL) is commonly seen in patients with attention-deficit/hyperactivity disorder (ADHD). The reasons for this association remain currently unknown. To address this question, we examined the relationship between ADHD and EL symptoms, and performance on a range of neuropsychological tasks to clarify whether EL symptoms are predicted by particular cognitive and/or motivational dysfunctions and whether these associations are mediated by the presence of ADHD symptoms. Methods: A large multi-site sample of 424 carefully diagnosed ADHD cases and 564 unaffected siblings and controls aged 618 years performed a broad neuropsychological test battery, including a Go/No-Go …
IMPAIRED DECISION-MAKING AND DIFFUSION ORIENTATIONAL COMPLEXITY IN PEOPLE WITH MULTIPLE SCLEROSIS
2013
Objective Difficulties with decision-making have been reported in people with multiple sclerosis (MS). It is however unclear what aspect of decision making is impaired, for example whether they are more impulsive, and how any impairments relate to grey matter pathology. In this study we assess grey matter microstructure using a novel measure of the number of diffusion orientations on diffusion MRI “diffusion orientation complexity (DOC)”. We studied DOC in cortical areas known to be associated with decision making and looked at its associations with performance on the Cambridge Gambling Task (CGT). Method One hundred and five patients with MS (61 RR, 26 SP, 18 PP; mean age: 45.9 years) and …
The co-occurrence of nonsuicidal and suicidal self-injurious acts in adult women: A pilot study of similarities and differences
2015
Nonsuicidal self-injury (NSSI) and suicidal self-injury (SSI) co-occur in adults. The purpose of the current study was to examine differences and similarities in NSSI and SSI in adult women with respect to (1) methods used and lethality of methods, (2) intent and impulsivity of act, (3) precipitating events, and (4) consequences. The data consist of variables pertaining to 46 self-injurious acts committed by 16 Finnish female participants and recorded using Suicide Attempt Self-Injury Interviews (SASII). The data were analyzed using variables weighted by the number of acts. This study found several differences as well as similarities between the acts of SSI and those of NSSI: (a) the respec…
Effects of High Frequency Repetitive Transcranial Magnetic Stimulation (HF-rTMS) on Delay Discounting in Major Depressive Disorder: An Open-Label Unc…
2019
Background: Delay discounting (DD) refers to the decrease of a present subjective value of a future reward as the delay of its delivery increases. Major depressive disorder (MDD), besides core emotional and physical symptoms, involves difficulties in reward processing. Depressed patients often display greater temporal discounting rates than healthy subjects. Repetitive transcranial magnetic stimulation (rTMS) is a non-invasive brain stimulation technique applied in several countries to adult patients with treatment resistant depression. Studies suggest that this technique can be used to modulate DD, but no trial has assessed its effects on depressed patients. Methods: In this open-label unc…
Attention-deficit/hyperactivity disorder in adults: update on clinical presentation and care
2014
Attention-deficit/hyperactivity disorder (ADHD) is characterized by traitlike symptoms, with stable features frequently emerging in early childhood and persisting throughout adolescence and adulthood. The hallmarks are pervasive, developmentally inappropriate levels of inattention, hyperactivity and impulsivity leading to impairments in family life, social life, academic performance, and occupational functioning. Emotional lability is a commonly associated feature that is a further source of impairment. Diagnosis rests on a comprehensive assessment of developmental psychiatric history and current status, following DSM-5 guidelines on ADHD classification and diagnostic thresholds for adults.…
Pharmacotherapy of Borderline Personality Disorder: A Metaanalysis of Randomised Controlled Trials
2009
Background:In Borderline Personality Disorder (BPD), pharmacotherapy is used for the treatment of specific BPD pathology facets, such as cognitive-perceptual, affective, or impulsivity symptoms. Due to the polymorphic phenomenology of the disorder, different classes of drugs are used, e.g., antipsychotics, antidepressants, or mood stabilizers.Aims:To evaluate the up-to-date evidence of drug treatment efficacy for BPD.Method:A systematic review and metaanalysis of randomised controlled trials was done. All randomised comparisons of drug vs. placebo, drug vs. drug, or drug vs. a combination of drugs in adult BPD patients were eligible for inclusion. Outcomes comprised BPD core pathology as de…
Can transcranial direct current stimulation (tDCS) improve impulsivity in healthy and psychiatric adult populations? A systematic review.
2020
Impulsivity is a multidimensional phenomenon that remains hard to define. It compounds the core pathological construct of many neuropsychiatric illnesses, and despite its close relation to suicide risk, it currently has no specific treatment. Transcranial direct current stimulation (tDCS) is a non-invasive brain stimulation technique whose application results in cognitive function improvement, both in healthy and psychiatric populations. Following PRISMA recommendations, a systematic review of the literature concerning tDCS's effects on impulsive behaviour was performed using the PubMed database. The research was based on the combination of the keyword 'tDCS' with 'impulsivity', 'response i…
Application of the Chinese Version of the BIS/BAS Scales in Participants With a Substance Use Disorder: An Analysis of Psychometric Properties and Co…
2020
Carver and White developed the Behavioral Inhibition/Behavioral Activation Scales (the BIS/BAS Scales) based on Reinforcement Sensitivity Theory proposed by Gray. Subsequent studies proposed that substance abuse was closely related to Behavioral Inhibition System (BIS) and Behavioral Activation System (BAS). However, researches on the psychometric properties of the BIS/BAS scales in clinical samples are scarce. The present study was conducted to analyze the applicability of the BIS/BAS scales in a sample suffering from a substance use disorder (SUD) and undergoing treatment in compulsory detoxification institutions (n = 1117). Meanwhile, 822 community residents were selected for comparison.…
Performance-based tests versus behavioral ratings in the assessment of executive functioning in preschoolers: associations with ADHD symptoms and rea…
2015
The early assessment of the executive processes using ecologically valid instruments is essential for identifying deficits and planning actions to deal with possible adverse consequences. The present study has two different objectives. The first objective is to analyze the relationship between preschoolers' performance on tests of Working Memory and Inhibition and parents' and teachers' ratings of these executive functions (EFs) using the Behavior Rating Inventory of Executive Function (BRIEF). The second objective consists of studying the predictive value of the different EF measures (performance-based test and rating scales) on Inattention and Hyperactivity/Impulsivity behaviors and on in…
