Pilot Trial of Neural Correlates of Response to Treatment of PTSD-Associated Impulsive Aggression
Impulsive Aggression, Posttraumatic Stress Disorder
About this trial
This is an interventional treatment trial for Impulsive Aggression focused on measuring Impulsive Aggression, Posttraumatic Stress Disorder
Eligibility Criteria
Inclusion Criteria: - Inclusion Criteria for both groups will be right-handed adult combat veterans over the age of 18 who meet criteria for PTSD via Structured Clinical Interview (SCID-I, First, 2002) and Impulsive Aggression as the primary diagnoses. To be included in the study with a designation of Impulsive Aggression, patients must have committed at least three aggressive acts over the preceding three months meeting criteria for impulsive aggressive acts by Impulsive/Premeditated Aggression Scales (IPAS) criteria (Stanford et al 2003) based on a semi-structured interview of the patient and his/her significant other. An impulsive aggressive act is defined as a hair-trigger, non-premeditated response to a stimulus that results in an immediate aggressive act or an agitated state that culminates in an aggressive act, which is clearly disproportionate to the triggering stimulus. Inclusion criteria for both groups also includes the availability for participation of a significant other who can participate in the study. The significant other will need to accompany the study participant to the initial assessment interview and complete measures of aggressive acts which have been committed by the study participants in the three months prior to the start of the study, and aggressive acts during the previous two weeks at two-week interval follow-up visits throughout the eight-week treatment period. Exclusion Criteria: Exclusion Criteria for both groups will include exclusion criteria for MRI scanning, and known claustrophobia requiring sedation in the past during MRI scanning. MRI exclusion criteria will include metallic implants, implanted devices of any kind, such as a cardiac pacemaker, cardiac defibrillator, insulin pump, vagal nerve stimulator, cochlear implant, metallic splinters in the eye, ferromagnetic clips or metal in the head or brain (as from previous injury or head/brain surgery including brain aneurysm clipping), lead wires of any kind, clips or stints anywhere in the body, such as clips for arterial aneurysm clipping, stints in cardiac arteries or other arteries anywhere in the body, prosthetic heart valves, stapedial implants of any kind (implants in the inner ear).
