Filter by:From a psychoevolutionary perspective, anger is a universal emotion that can serve the function of making us aware of wrongdoing and motivating us to undo/correct the wrongdoing. However, it is well recognized in clinical psychology that anger can be maladaptive, often causing distress and impairment in various areas of day-to-day life; untreated maladaptive anger has been found to raise the risk of certain physical health problems e.g., hypertension and coronary heart disease. At the very extreme, rage has been implicated in aggression and violence. Not surprisingly, there has been a widespread quest for anger treatments or what is popularly called "anger management". One treatment approach that has received increasing empirical support is Cognitive Behavioral Affective Therapy (CBAT), which has been applied to patients with chemical dependence and individuals with chronic pain. To extend this programmatic line of research, the proposed research aims to evaluate the efficacy of CBAT in reducing multiple (psychometric and self-monitored) measures of anger within a community sample.
Alcohol intoxication is responsible for a large proportion of violent crime/assault and personal injury in our society. While a number of variables have been associated with alcohol-related aggression, high trait aggression and impaired executive function have been identified as key factors. Both Alcohol Use Disorder (AUD) and Impulsive Aggression behavior (AGG) are related to impaired social-emotional information processing (SEIP) whereby social threat cues, especially ones that are ambiguous in nature, lead to hostile attribution and negative emotional response to the "other" and, then, aggression against the "other". Thus, understanding the underlying neuroscience of SEIP under the influence of alcohol will be critical to identifying targets for intervention to reduce alcohol-related aggressive behavior. In addition to potential pharmacologic and cognitive-behavioral based interventions, such interventions may also involve the rehabilitation of aberrant neuronal circuits underlying social cognitive function through neuroplasticity-based remediation exercises. This study is designed to see how brain activation of cortico-limbic circuits involving social-emotional information processing, analyzed by fMRI Imaging, are impacted by alcohol administration in those with and without aggressive disorders and with and without alcohol use disorder.
The goal of this experimental medicine clinical trial is to test the hypothesis that nitrous oxide inhalation will result in a change in neurocircuit function in healthy controls and in individuals with impulsive aggressive tendencies. The main question aims to answer are: Does Nitrous Oxide normalize brain circuit function in impulsively aggressive individuals 24 hours after inhalation. Participants will undergo a 60 minute inhalation session with 50% Nitrous Oxide (or room air at another session) and then undergo an fMRI scan 24 hours later. Researchers will compare healthy controls and impulsively aggressive individuals to see if Nitrous Oxide can normalize the function of cortico-limbic circuits in the latter group.
The investigators are studying how certain drugs can reduce anger outbursts in people with anger problems. In this study the investigators seek to determine if a single 34 mg (two 17 mg tablets) oral dose of the 5-HT2a receptor blocker, pimavanserin, will reduce aggressive responding in individuals with impulsive aggression (Intermittent Explosive Disorder: IED) on a laboratory task that assesses aggression (Taylor Aggression Paradigm: TAP). We will also be examining how this drug impacts hostile social cognition e.g., hostile attribution). If pimvanserin reduces aggression in this study a next step would be a placebo-controlled treatment trial of pimavanserin in study participants with IED. Participation will first involve a remote (e.g., TEAMS) screening session. If potential study participants appear eligible they will come into the lab for an in-person session where participants will complete interviews and questionnaires and have a medical evaluation (including a physical exam, electrocardiogram, and screens for alcohol and drug use). During the next study session, participants will complete a diagnostic interview and a series of questionnaires, all of which can all take place on-line. During the next two sessions (which will be in-person) participants will undergo two (2) study sessions during which study participants will be given a study drug (orally). The drug given, pimavanserin, is currently available and is known to block serotonin receptors thought to be involved in regulating anger. After participants take the study drug, study participants will complete questionnaires and computer tasks for assessment of aggression and of hostile social cognition. Each of these two in-person study sessions will take at least eight (8) hours. A final on-line session will be done to make certain the investigators have all the data required by the study protocol.
This randomized controlled trial will test a computerized cognitive bias modification program (CBM) to treat attention and interpretive biases in patients with primary aggression.
This is a multicenter, randomized, double-blind, placebo-controlled study to evaluate AVP-786 for the treatment of Intermittent Explosive Disorder (IED).
This study is designed to explore the safety and tolerability, and to compare the activity of SRX246 against placebo, in adults with Intermittent Explosive Disorder (IED). Adult Male and Female subjects with a current diagnosis of IED will be enrolled. After a two-week baseline lead-in phase, study subjects who continue to meet enrollment criteria will be randomized to either SRX246 or Placebo treatment groups. Study subjects will be examined and asked to answer questionnaires at weekly scheduled visits throughout the trial. The study results will be determined based on any changes observed over the study period.
Children with explosive aggression are often rejected by their peers, placed in special classroom, and contribute to family discord. When psychotherapy and family therapy is unsuccessful, medications are often used. Current medications are stimulants (e.g. methylphenidate, dextroamphetamine), anticonvulsants (e.g. Divalproex) and antipsychotics (olanzapine, risperidone). At this time, the available medications are of limited usefulness, either because they do not always work or because they have side effects such as weight gain or insomnia. There is a clear need for new medications to treat explosive aggression when psychotherapy is unsuccessful. The hypothesis of this study is the medication Intuniv when combined with psychotherapy will be more helpful to children with explosive aggression than placebo combined with psychotherapy. Intuniv is a long acting form of guanfacine, a medication approved by the FDA for treatment of Attention Deficit Hyperactivity Disorder. Intuniv is not a stimulant, nor is it an anticonvulsant, nor is it an antipsychotic. The children in this study will be between the ages of 6 and 12 and meet Diagnostic and Statistical Manual of Psychiatry Fourth Edition, Text Revision (DSM-IV-TR) criteria for Intermittent Explosive Disorder.
The goal of this study is to examine the effectiveness two forms of psychotherapy (also known as "talk therapy" ) for individuals with anger and aggression problems. Anger and aggression are everywhere - on the road, in the schools, at little league games, at home, and at work. In this study we are testing usefulness of anger management techniques in reducing symptoms of Intermittent Explosive Disorder (IED) and impulsive, aggressive behavior.
This study was developed in order to assess the effects of risperidone (Risperdal) as compared with placebo on cognitive-motor performance (attention, memory, and hand steadiness) and body movements. We propose to study the effects of risperidone on cognitive-motor performance in children already medicated for severe conduct problems. We would also like to look at safety by assessing these children for dyskinetic movements. We already have a sizable cohort of children maintained on risperidone. Our hypotheses are as follows: 1. Risperidone will have no adverse effects on cognitive-motor performance in children who have received maintenance therapy for 4 to 20 months. 2. Children tested during placebo will show no more dyskinetic movements than during risperidone treatment (i.e., there will be no unmasking of tardive dyskinesia).
