Examining the neurobiology of non-suicidal self-injury in children and adolescents: The role of reward responsivity
Although prior work has shown heightened response to negative outcomes and reduced response to positive outcomes in youth with a history of non-suicidal self-injury (NSSI), little is known about the neural processes underlying these responses. Thus, this study examined associations between NSSI engagement and functional activation in specific regions of interest (ROIs) and whole-brain connectivity […]
Working memory mediates increased negative affect and suicidal ideation in childhood attention-deficit/hyperactivity disorder
Children with attention-deficit/hyperactivity disorder (ADHD) are at greater risk for suicidal ideation and suicide attempts compared to those without ADHD. Increased risk is at least partially attributable to a subset of children with ADHD and comorbid depression or disruptive behavior disorders; however, the early predictors and mechanisms driving increased risk are not well understood. Here, […]
Deficits in executive function (EF) have been proposed as a possible explanation for the “cognitive rigidity” often observed in suicidal individuals. This article provides a systematic review of the existing literature testing relations between EF and suicidality, across various diagnostic and demographic populations, using the influential multidimensional model of EF proposed by Miyake and colleagues (2000) as […]
The relationship of self-reported executive functioning to suicide ideation and attempts: Findings from a large U.S.-based online sample.
An increasing number of studies demonstrate that individuals with a history of suicidality exhibit impaired executive functioning abilities. The current study examines whether these differences are linked to suicidal thoughts or suicidal acts—a crucial distinction given that most people who think about suicide will not act on their thoughts. A large online sample of U.S. […]
Building the brain’s “air traffic control” system: How early experiences shape the development of executive function: Working paper 11.
Being able to focus, hold, and work with information in mind, filter distractions, and switch gears is like having an air traffic control system at a busy airport to manage the arrivals and departures of dozens of planes on multiple runways. In the brain, this air traffic control mechanism is called executive function, a group […]
Executive functioning as a component of suicide risk assessment: Clarifying its role in standard clinical applications.
Clinically, because executive dysfunction (e.g., impulsivity, insight, thinking process) is often thought of in the context of those with traumatic brain injuries and other neurologic conditions, it~ formal assessment has historically been seen as the domain of those who assess and treat patients with neurologic disease. However, mental health counselors (MHCs) could benefit from learning […]
