Lauren L Drag, Michael Mlynash, Huda Nassar, Elizabeth Osborn, Da E Kim, Martin S Angst, Nima Aghaeepour, Marion Buckwalter, Maarten G Lansberg,

BACKGROUND:Stroke increases the risk of cognitive impairment even several years after the stroke event. The exact mechanisms of post-stroke cognitive decline are unclear, but the immunological response to stroke might play a role. The aims of the StrokeCog study are to examine the associations between immunological responses and long-term post-stroke ... Read more >>

Patterns of frontoparietal activation as a marker for unsuccessful visuospatial processing in healthy aging.

Lauren L Drag, Sharee N Light, Scott A Langenecker, Kathleen E Hazlett, Elisabeth A Wilde, Robert Welsh, Brett A Steinberg, Linas A Bieliauskas,

Visuospatial abilities are sensitive to age-related decline, although the neural basis for this decline (and its everyday behavioral correlates) is as yet poorly understood. fMRI was employed to examine age-related differences in patterns of functional activation that underlie changes in visuospatial processing. All participants completed a brief neuropsychological battery and ... Read more >>

Incidental Learning: A Brief, Valid Measure of Memory Based on the WAIS-IV Vocabulary and Similarities Subtests.

Robert J Spencer, Jaclyn Reckow, Lauren L Drag, Linas A Bieliauskas,

We assessed the validity of a brief incidental learning measure based on the Similarities and Vocabulary subtests of the Wechsler Adult Intelligence Scale-Fourth Edition (WAIS-IV).Most neuropsychological assessments for memory require intentional learning, but incidental learning occurs without explicit instruction. Incidental memory tests such as the WAIS-III Symbol Digit Coding subtest ... Read more >>

Neuropsychological test validity in Veterans presenting with subjective complaints of 'very severe' cognitive symptoms following mild traumatic brain injury.

Robert J Spencer, Brigid Waldron-Perrine, Lauren L Drag, Percival H Pangilinan, Bradley N Axelrod, Linas A Bieliauskas,

This study explored the utility of combining data from measures of performance validity and symptom validity among Veterans undergoing neuropsychological evaluation for mild traumatic brain injury (mTBI).Persistent cognitive impairments following mTBI are often reported by returning combat veterans. However, objectively-measured cognitive deficits are not common among individuals with mTBI, raising ... Read more >>

The Hospital Anxiety and Depression Scale (HADS) is a brief self-report measure of anxiety and depression symptoms. This study examined the internal consistency and factor structure of the HADS among Veterans in a polytrauma/traumatic brain injury clinic. The sample consisted of 312 Veterans. A confirmatory factor analysis of the depression ... Read more >>

Limited usefulness of the Rey Fifteen-Item Test in detection of invalid performance in veterans suspected of mild traumatic brain injury.

Jennifer M Flaherty, Robert J Spencer, Lauren L Drag, Percival H Pangilinan, Linas A Bieliauskas,

This study explored using the FIT as a measure of performance validity among veterans undergoing neuropsychological evaluation for mild traumatic brain injury (mTBI).The Rey Fifteen-Item Memory Test (FIT) is a performance validity measure criticized for poor sensitivity.Two hundred and fifty-seven veterans completed the FIT and Wechsler Adult Intelligence Scale, Fourth ...

WAIS-IV reliable digit span is no more accurate than age corrected scaled score as an indicator of invalid performance in a veteran sample undergoing evaluation for mTBI.

Robert J Spencer, Bradley N Axelrod, Lauren L Drag, Brigid Waldron-Perrine, Percival H Pangilinan, Linas A Bieliauskas,

Reliable Digit Span (RDS) is a measure of effort derived from the Digit Span subtest of the Wechsler intelligence scales. Some authors have suggested that the age-corrected scaled score provides a more accurate measure of effort than RDS. This study examined the relative diagnostic accuracy of the traditional RDS, an ... Read more >>

The influence of sleep and mood on cognitive functioning among veterans being evaluated for mild traumatic brain injury.

Brigid Waldron-Perrine, Adam P McGuire, Robert J Spencer, Lauren L Drag, Percival H Pangilinan, Linas A Bieliauskas,

OBJECTIVE:Veterans undergoing evaluation for mild traumatic brain injury commonly report insomnia, psychiatric symptoms, and cognitive dysfunction. This study examines the effects of self-reported amount of sleep and subjective sleep quality on neuropsychological test performance. METHOD:262 veterans were seen for neuropsychological assessment in a Veterans Affairs traumatic brain injury clinic. All ... Read more >>

The contributions of self-reported injury characteristics and psychiatric symptoms to cognitive functioning in OEF/OIF veterans with mild traumatic brain injury.

Lauren L Drag, Robert J Spencer, Sara J Walker, Percival H Pangilinan, Linas A Bieliauskas,

Mild traumatic brain injury (mTBI) affects a significant number of combat veterans returning from Operation Enduring Freedom/Operation Iraqi Freedom (OEF/OIF). Although resolution of mTBI symptoms is expected over time, some individuals continue to report lingering cognitive difficulties. This study examined the contributions of self-reported mTBI injury characteristics (e.g., loss of ... Read more >>

Predictors of perceived need for medical care in an inpatient rehabilitation unit: an update.

Lauren L Drag, Elvina W Chen, Linas A Bieliauskas,

Limited awareness of illness, or poor insight, has been associated with poor treatment outcomes and prognoses in both psychiatric and medical populations. We examined predictors of insight in a sample of 403 patients in an inpatient rehabilitation unit at a Midwest Veterans Affairs Medical Center. A multiple regression analysis revealed ...

Self-reported cognitive symptoms following mild traumatic brain injury are poorly associated with neuropsychological performance in OIF/OEF veterans.

Robert J Spencer, Lauren L Drag, Sara J Walker, Linas A Bieliauskas,

Mild traumatic brain injury (mTBI) is not uncommon among Operation Iraqi Freedom/Operation Enduring Freedom (OIF/OEF) veterans, and many individuals within this group report lingering cognitive difficulties following their injury. For Department of Veterans Affairs clinicians, an accurate assessment of cognitive symptoms is important in providing appropriate clinical care. Although self-assessment ... Read more >>

Results from the cognitive changes and retirement among senior surgeons self-report survey.

H Jin Lee, Lauren L Drag, Linas A Bieliauskas, Scott A Langenecker, Christopher Graver, Jillian O'Neill, Lazar Greenfield,

BACKGROUND: The Cognitive Changes and Retirement among Senior Surgeons (CCRASS) study suggested that although subjective cognitive awareness may play a role in surgeons' retirement decisions, self-perceived cognitive decline did not predict objective cognitive performance. This article summarizes results from all participants who completed the survey portion of the CCRASS study. ... Read more >>

Source memory and frontal functioning in Parkinson's disease.

Lauren L Drag, Linas A Bieliauskas, Alfred W Kaszniak, Nicolaas I Bohnen, Elizabeth L Glisky,

The most extensively described pathological abnormality in Parkinson's disease (PD) is loss of dopaminergic neurons in the substantia nigra pars compacta and the ventral tegmental area, with degeneration of their striatal terminals. Because of the intimate connections between the striatum and the frontal lobes, individuals with PD often demonstrate impairments ... Read more >>
