The neuropsychological presentation of women with epilepsy: Clinical considerations and future directions.

Cognitive, mood, and behavioral changes are common among persons with epilepsy (PWE), resulting in a complex neuropsychological presentation. Women with epilepsy (WWE) represent a distinct cohort within the broader epilepsy population due to sex and gender-specific factors impacting epilepsy semiology and treatment. However, unique neuropsychological profiles among WWE have not been established.

Cognitive "success" in the setting of performance validity test failure.

Background: Although studies have shown unique variance contributions from performance invalidity, it is difficult to interpret the meaning of cognitive data in the setting of performance validity test (PVT) failure. The current study aimed to examine cognitive outcomes in this context.

Method: Two hundred and twenty-two veterans with a history of mild traumatic brain injury referred for clinical evaluation completed cognitive and performance validity measures.

Embedded cognitive and emotional/affective self-reported symptom validity indices on the patient competency rating scale.

Objective: Although there is an abundance of research on stand-alone and embedded performance validity tests and stand-alone symptom validity tests (SVTs), less emphasis has been placed on embedded SVTs. The goal of the current study was to examine the ability of embedded indicators within the Patient Competency Rating Scale (PCRS) to separately detect invalid cognitive and/or emotional/affective symptom responding.

Method: Participants included 299 veterans assessed in a VA medical center epilepsy monitoring unit from 2013-2017 (mean age = 48.

Characterizing women veterans receiving seizure care in the veterans affairs healthcare system.

Objective: The number and proportion of women served by the Veterans Health Administration (VHA) is rapidly expanding, necessitating better characterization of factors unique to this population. While nascent literature has begun to better characterize women within the broader seizure population, women Veterans remain an understudied sample. To expand our clinical understanding of women with seizures, we assessed demographic and clinical characteristics, as well as psychiatric/military histories in women receiving care from an Epilepsy Center of Excellence within the VA Healthcare System.

The Relationship between Health Literacy and Comfort with Teleneuropsychology in a Veteran Sample.

Objective: Health literacy is a strong psychosocial determinant of health disparities and has been found to relate to various aspects of health-related technology use. With the increased implementation of neuropsychological services performed via telehealth during the coronavirus disease 2019 pandemic, the relationship between health literacy and comfort with teleneuropsychology warrants further investigation.

Method: The present study examined 77 Veterans participating in neuropsychological evaluations as a part of standard clinical care.

The Severe Impairment Profile: A Conceptual Shift.

Objective: The current study sought to evaluate and replicate the severe impairment profile (SIP) of the Word Memory Test (WMT) in patients referred for dementia evaluations.

Method: The sample consisted of 125 patients referred for a neuropsychological evaluation at a large Veterans Affairs Medical Center. Patients were assigned a Clinical Dementia Rating (CDR) by blind raters, and were classified according to their performance on performance validity testing.

Factors related to satisfaction with life in veterans with mild traumatic brain injury.

Purpose/objective: Satisfaction with life (SWL) is an important measure of outcome in rehabilitation. Previous research suggests that those with a history of traumatic brain injury (TBI), even mild TBI, report lower levels of life satisfaction when compared with the noninjured population. Although is it possible that TBI has a direct effect on SWL, various medical and psychosocial factors commonly affecting those recovering from TBI likely contribute to SWL.

Relative Utility of Performance and Symptom Validity Tests.

This investigation adds to the burgeoning body of research concerned with discriminating performance and symptom validity tests (SVTs) through examination of their differential relationships with cognitive performance and symptom self-report measures. To the authors' current knowledge, prior studies have not assessed differences between participants who fail either a performance validity test (PVT) or an SVT but not both. As part of their neuropsychological evaluations at four Veterans Affairs medical centers across the United States, participants were administered a fixed, standardized battery that consisted of performance validity, symptom validity, cognitive performance, and symptom self-report measures.

The dangers of failing one or more performance validity tests in individuals claiming mild traumatic brain injury-related postconcussive symptoms.

Evaluating performance validity is important in any neuropsychological assessment, and prior research recommends a threshold for invalid performance of two or more performance validity test (PVT) failures. However, extant findings also indicate that failing a single PVT is associated with significant changes in neuropsychological performance. The current study sought to determine if there is an appreciable difference in neuropsychological testing results between individuals failing different numbers of PVTs.

Clinician versus Veteran ratings on the Mayo-Portland Participation Index in veterans with a history of mild traumatic brain injury.

Background: The Department of Veterans Affairs is encouraging administration of the Mayo-Portland Adaptability Inventory-4 Participation Index (M2PI) to identify long-term psychosocial outcomes of Operation Enduring Freedom (OEF), Operation Iraqi Freedom (OIF), and Operation New Dawn (OND) Veterans with a history of traumatic brain injury (TBI).

Objective: To evaluate clinician and Veteran interrater reliability and how response validity influences M2PI item ratings.

Participants: A total of 122 OEF/OIF/OND Veterans who reported a history consistent with mild TBI during deployment and were referred for neuropsychological evaluation following Comprehensive TBI Evaluation.

Ecological validity of performance validity testing.

Performance validity tests (PVTs) have been shown to relate to neuropsychological performance, but no studies have looked at the ecological validity of these measures. Data from 131 veterans with a history of mild traumatic brain injury from a multicenter Veterans Administration consortium were examined to determine the relation between scores on a self-report version of the Mayo-Portland Adaptability Inventory Participation Index, a measure of community participation, and the Word Memory Test, a PVT. A restricted regression model, including education, age, history of loss of consciousness, cognitive measures, and a measure of symptom validity test performance, was not significantly associated with self-reported community reintegration.

PTSD and cognitive functioning: importance of including performance validity testing.

Many studies have observed an association between post-traumatic stress disorder (PTSD) and cognitive deficits across several domains including memory, attention, and executive functioning. The inclusion of response bias measures in these studies, however, remains largely unaddressed. The purpose of this study was to identify possible cognitive impairments correlated with PTSD in returning OEF/OIF/OND veterans after excluding individuals failing a well-validated performance validity test.

The relation of depression and anxiety to measures of executive functioning in a mixed psychiatric sample.

The relationship between mood and executive functioning is of particular importance to neuropsychologists working with mixed psychiatric samples. The present study evaluated the relation of self-reported depression and anxiety to several common measures of executive functioning: the Wisconsin Card Sorting Test, the Trail Making Test, the Controlled Oral Word Association, and the Letter-Number Sequencing subtest of the Weschler Adult Intelligence Scale-III. Records from 86 adult patients evaluated in an outpatient psychiatry unit were examined.

A new euglobulin clot lysis assay for global fibrinolysis.

Plasma fibrinolytic activity has been measured by the euglobulin clot lysis time (ELT) since the late 1950s. The euglobulin clot lysis assay (ECLA) method has been modified using a computerized kinetic spectrophotometric microtiter plate reader and measures optical density changes of recalcified euglobulin fraction of plasma samples over time. This method has been applied to normal healthy adults, children, pregnant women and newborn infants, which represent physiologic extremes of the ELT.
