Judgment of Line Orientation: an examination of eight short forms.

Robert J Spencer, Carrington R Wendell, Paul P Giggey, Stephen L Seliger, Leslie I Katzel, Shari R Waldstein,

The Judgment of Line Orientation (JLO) test is a commonly used measure of visuospatial perception. Because of its length, several short forms have appeared in the literature. We examined the internal consistency of the JLO and eight of its published short forms among 128 undergraduates, 203 healthy older adults, and ... Read more >>

Psychometric limitations of the mini-mental state examination among nondemented older adults: an evaluation of neurocognitive and magnetic resonance imaging correlates.

Robert J Spencer, Carrington R Wendell, Paul P Giggey, Leslie I Katzel, David M Lefkowitz, Eliot L Siegel, Shari R Waldstein,

BACKGROUND/STUDY CONTEXT: Although many of the Mini-Mental State Examination's (MMSE) limitations are well accepted among geriatricians, neuropsychologists, and other interested clinicians and researchers, its continued use in psychometrically unsound ways suggests that additional investigation and dissemination of information are sorely needed. The authors aimed to describe the reliability and validity ... 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 >>

Neuropsychological performance of native versus non-native English speakers.

Jason E Kisser, Carrington R Wendell, Robert J Spencer, Shari R Waldstein,

Relatively little is known about differences in English-administered, clinical neuropsychological test performance between native versus non-native English speakers, with prior literature yielding mixed findings. The purpose of this study was to examine the performance of native and non-native English speakers with similar age and educational backgrounds on a variety of ... 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 >>

Shari R Waldstein, David M Lefkowitz, Eliot L Siegel, William F Rosenberger, Robert J Spencer, Carol F Tankard, Zorayr Manukyan, Evie J Gerber, Leslie Katzel,

OBJECTIVE:To examine relations of blood pressure (BP) with single photon emission computed tomography (SPECT)-derived estimates of cerebral blood flow in older men and women. METHODS:Seventy-four stroke and dementia-free, community-dwelling older adults (ages 54-83 years; 68% men; 91% white) free of major medical, neurological, or psychiatric disease, engaged in clinical assessment ...

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 >>

Giant extraskeletal osteochondroma of the plantar midfoot arch.

Robert J Spencer, Neal M Blitz,

Osteochondromas found within the soft tissue without osseous or intra-articular involvement are better described as extraskeletal osteochondromas. They are slow-growing, benign, osseous tumors, and are often misdiagnosed as conventional osteochondromas. Though extraskeletal osteochondromas are rare, they typically affect the digits of the hands or feet. We present a patient with ... Read more >>

The Cognitive Estimation Test (CET): psychometric limitations in neurorehabilitation populations.

Robert J Spencer, Doug Johnson-Greene,

The Cognitive Estimation Test (CET), which purportedly assesses aspects of executive functioning, consists of answering questions that require deductive reasoning. This paper explored the CET's psychometric properties in neurorehabilitation samples, including its reliability and strength of association with tests involving varying levels of executive skill. Among 112 patients (age = ... Read more >>
