The development of the Cognitive Assessment for Tagalog Speakers (CATS): A culturally and linguistically tailored test battery for Filipino Americans.

Introduction: Filipino Americans are one of the largest Asian American and Pacific Islander (AAPI) populations in the United States (US). Previous studies suggest that Filipino Americans have one of the highest incidence rates of Alzheimer's disease and related dementias (ADRD) among AAPI subgroups. Despite the expected increase in Filipino Americans with ADRD, no studies to-date have validated neuropsychological measures in the United States for speakers of Tagalog, a major language spoken by Filipino Americans.

Improvement in executive functioning after Goal-Oriented Attentional Self-Regulation training is associated with reduction in PTSD hyperarousal symptoms among veterans with comorbid PTSD and mild TBI.

Goal-Oriented Attentional Self-Regulation (GOALS) is a cognitive rehabilitation training program that combines mindfulness-based attention regulation with individualized goal management strategies to improve functioning in daily life after traumatic brain injury (TBI). While not a specific target of GOALS training, previous research has indicated improvements in emotional functioning following GOALS training, specifically symptoms related to depression and posttraumatic stress disorder (PTSD). The current study is based on the hypothesis that improvements in cognitive control processes related to executive functioning and attention after GOALS training generalize to improvements in emotional functioning, thereby resulting in reductions in emotional distress.

Goal-Oriented Attention Self-Regulation Training Improves Executive Functioning in Veterans with Post-Traumatic Stress Disorder and Mild Traumatic Brain Injury.

Difficulties in executive-control functions are common sequelae of both traumatic brain injury (TBI) and post-traumatic stress disorder (PTSD). The goal of this study was to assess whether a cognitive rehabilitation training that was applied successfully in civilian and military TBI would be effective for military Veterans with comorbid PTSD and mild TBI (mTBI). In the previous study, Veterans with a history of mild to severe TBI improved significantly after goal-oriented attentional self-regulation (GOALS) training on measures of attention/executive function, functional task performance, and emotional regulation.

Long-Term Effect of Cognitive Rehabilitation Regardless of Prerehabilitation Cognitive Status for Veterans with TBI.

Persisting difficulties in executive functioning (EF) are common after traumatic brain injury (TBI). Cognitive rehabilitation can be effective, but the impact of pretreatment neurocognitive functioning on long term effects of rehabilitation is unknown. Because this information can impact treatment planning, we examined the relationship between prerehabilitation neurocognitive status and long-term effects of EF training.

Long-term effects of executive function training among veterans with chronic TBI.

: To investigate long-term effects of GOALS executive function training in Veterans with chronic TBI. In a recently completed study Veterans with chronic TBI showed improvement immediately post-GOALS but not control training on measures of executive function, functional task performance, and emotion regulation. We now examine the long-term maintenance of post-GOALS training changes in the same sample.

Quantification of adverse events associated with functional MRI scanning and with real-time fMRI-based training.

Background: Although functional magnetic resonance imaging (fMRI) is in widespread research use, the safety of this approach has not been extensively quantitatively evaluated. Real-time fMRI (rtfMRI)-based training paradigms use fMRI neurofeedback and cognitive strategies to alter regional brain activation, and are currently being evaluated as a novel approach to treat neurological and psychiatric conditions.

Purpose: The purpose of this study is to determine the incidence and severity of any adverse events that might be caused by changes in brain activation brought about through fMRI or through rtfMRI-based training paradigms.

Calculation of the confidence intervals for transformation parameters in the registration of medical images.

Images from different individuals typically cannot be registered precisely because anatomical features within the images differ across the people imaged and because the current methods for image registration have inherent technological limitations that interfere with perfect registration. Quantifying the inevitable error in image registration is therefore of crucial importance in assessing the effects that image misregistration may have on subsequent analyses in an imaging study. We have developed a mathematical framework for quantifying errors in registration by computing the confidence intervals of the estimated parameters (3 translations, 3 rotations, and 1 global scale) for the similarity transformation.
