workers compensation neuropsychology

Civil litigation involving the forensic neuropsychiatric evaluation of a personal injury case requires an assessment of damages and causation. The expert witness is obliged to integrate data from three critical sources of information: the review of records; the results of neuropsychological testing; and the findings from the clinical examination. In civil litigation involving a personal injury claim, the expert witness can be expected to address causation and prognosis of any neuropsychiatric damages. We discuss the undertaking of a forensic neuropsychiatric evaluation, psychiatric disorders often encountered in personal injury litigation, provide case vignettes and describe a number of special types of forensic neuropsychiatric evaluations, for example, Workers' Compensation, VA Disability and Social Security Disability...

Objective: The aim of this investigation was to provide information about the utility of the newly revised and renormed Minnesota Multiphasic Personality Inventory-3 (MMPI-3) over-reporting scales in a forensic disability sample. Method: Participants consisted of 550 non-head injury disability-related referrals (i.e. 95.6% for worker's compensation) and were primarily diagnosed with an adjustment disorder, depressive disorder, or posttraumatic stress disorder. Criterion measures included performance validity indicators and non-MMPI symptom validity indicators...

BACKGROUND: Organic solvent-induced chronic toxic encephalopathy (CTE) is known as a non-progressive disorder that does not progress after diagnosis. The authors present a case those symptoms worsened after continued exposure to organic solvent after returning to work. Because such a case has not been reported in South Korea to the best of our knowledge, we intend to report this case along with literature review. CASE PRESENTATION: A 59-year-old man, who performed painting job at a large shipyard for 20 years, was receiving hospital treatment mainly for depression...

OBJECTIVE: To investigate the predictive validity of the Word Memory Test (WMT), a verbal memory neuropsychological test developed as a performance validity measure to assess memory, effort, and performance consistency. DESIGN: Cohort study with 1-year follow-up. SETTING: Workers' compensation rehabilitation facility. PARTICIPANTS: Participants included workers' compensation claimants with work-related head injury (N=188; mean age, 44y; 161 men [85...

Harriet Hardy, protégé of Alice Hamilton, spent 1948 in the Health Division of Los Alamos Scientific Laboratory. The contemporary campaign for federal legislation to compensate nuclear workers brought to the fore living retirees in whose cases of occupational illness Hardy had a role in diagnosis or case management. A third case is documented in archival records. Methods of participatory action research were used to better document the cases and strategize in light of the evidence, thereby assisting the workers with compensation claims...

This study examined the relationship between lesion presence and localization and performance on measures of cognitive response bias, specifically in individuals purporting to have a traumatic brain injury. Ninety-two participants, all of whom were involved in workers' compensation or personal injury litigation, were administered an extensive neuropsychological battery, including neuroimaging (magnetic resonance imaging and computed tomography), at a neuropsychiatric clinic in Lexington, KY. Those with evidence of intracranial injury on neuroimaging findings were placed in the head injury lesion litigation group and were coded based on the anatomical location and type of intracranial injury...

The current study examined the over-reporting Validity Scales of the MMPI-2 Restructured Form (MMPI-2-RF; Ben-Porath & Tellegen, 2008/2011) in relation to the Slick, Sherman, and Iverson (1999) criteria for the diagnosis of Malingered Neurocognitive Dysfunction in a sample of 916 consecutive non-head injury disability claimants. The classification of Malingered Neurocognitive Dysfunction was based on scores from several cognitive symptom validity tests and response bias indicators built into traditional neuropsychological tests...

Three cases are presented of peculiar speech and language abnormalities that were evaluated in the context of personal injury lawsuit or workers compensation claims of brain dysfunction after mild traumatic brain injuries. Neuropsychological measures of effort and motivation showed evidence of suboptimal motivation or outright malingering. The speech and language abnormalities of these cases probably were not consistent with neurogenic features of dysfluent speech including stuttering or aphasia. We propose that severe dysfluency or language abnormalities persisting after a single, uncomplicated, mild traumatic brain injury are unusual and should elicit suspicion of a psychogenic origin...

The evaluation and management of mild traumatic brain injury (mTBI) in the occupational setting may pose significant challenges for even the most-seasoned practitioner. Providers must simultaneously address the clinical management of mTBI and be familiar with the systematic and administrative requirements related to the management of injured workers with mTBI who are covered by workers' compensation insurance, including causation, return to work, and the potential of permanent impairment. Given the primarily subjective nature of many mTBI symptoms, an injured worker with a delayed recovery may raise the question, if not suspicion, of symptom magnification and secondary gain...

Against the background of a growing interest in symptom validity assessment in European countries, new data on base rates of negative response bias is presented. A retrospective data analysis of forensic psychological evaluations was performed based on 398 patients with workers' compensation claims. 48 percent of all patients scored below cut-off in at least one symptom validity test (SVT) indicating possible negative response bias. However, different SVTs appear to have differing potential to identify negative response bias...

When considering a diagnosis of postconcussion syndrome, clinicians must systematically evaluate and eliminate the possible contribution of many differential diagnoses, comorbidities, and factors that may cause or maintain self-reported symptoms long after mild traumatic brain injury (MTBI). One potentially significant contributing factor is symptom exaggeration. The purpose of the study is to examine the influence of poor effort on self-reported symptoms (postconcussion symptoms and cognitive complaints) and neurocognitive test performance following MTBI...

OBJECTIVE: To provide an empirical estimate of the prevalence of malingered disability in patients with chronic pain who have financial incentive to appear disabled. DESIGN: Retrospective review of cases. SETTING: A private neuropsychologic clinic in a southeastern metropolitan area. PARTICIPANTS: Consecutive patients (N=508) referred for psychologic evaluation related to chronic pain over a 10-year period (1995-2005)...

The Structured Interview of Reported Symptoms (SIRS; Rogers et al., Structured interview of reported symptoms (SIRS) and professional manual, 1992) is a well-validated psychological measure for the assessment of feigned mental disorders (FMD) in clinical, forensic, and correctional settings. Comparatively little work has evaluated its usefulness in compensation and disability contexts. The present study examined SIRS data from 569 individuals undergoing forensic neuropsychiatric examinations for the purposes of workers' compensation, personal injury, or disability proceedings...

PRIMARY OBJECTIVE: To test the usefulness of a method to improve the measurement of prevalent mild traumatic brain injury (MTBI) among injured workers with a workers compensation claim. METHODS: Database codes were selected to identify MTBI cases in the Ontario workers compensation lost-time claims database. A random sample of 210 claims was selected, classified as MTBI or not, and used to calculate proportions with MTBI among code groups. The annual prevalence of MTBI in 1997 and 1998 was calculated by weighting the numerators with the appropriate proportions of MTBI within each code group...

An interdisciplinary task force of physicians and neuropsychologists with advanced training in impairment and disability assessment provided a review of the literature on malingering in chronic pain, medical disorders, and mental/cognitive disorders. Our review suggests that treating health care providers often do not consider malingering, even in cases of delayed recovery involving work injuries or other personal injuries, where there may be a significant incentive to feign or embellish symptoms or delay recovery...

PRIMARY OBJECTIVE: Motivation has an important influence on neuropsychological test performances. This study examined effort on the Word Memory Test (WMT) in groups with differing external incentives. RESEARCH DESIGN: 774 adults with Traumatic Brain Injury (TBI), tested as part of a Workers' Compensation, disability or personal injury claim stood to gain financially by appearing impaired on testing. In contrast, parents ordered by the Court to undergo a parenting assessment were highly motivated to do their best on cognitive tests because their goal was to regain custody of their children...

We retrospectively reviewed Victoria Symptom Validity Test (VSVT) in 374 patients who underwent neuropsychological assessment in an academic hospital-based practice. Patients were classified as either non-TBI clinically referred (generally patients referred from neurology, neurosurgery, or medicine), clinically referred TBI (no known external financial incentive), and non-clinical referrals (e.g., attorney-referred, Worker's Compensation). Three patients were not classified into any group and considered separately...

This study examined the sensitivity and false-positive error rate of reliable digit span (RDS) and the WAIS-III Digit Span (DS) scaled score in persons alleging toxic exposure and determined whether error rates differed from published rates in traumatic brain injury (TBI) and chronic pain (CP). Data were obtained from the files of 123 persons referred for neuropsychological evaluation related to alleged exposure to environmental and industrial substances. Malingering status was determined using the criteria of Slick, Sherman, and Iverson (1999)...

The purpose of this study was to determine if there is a dose-response relationship between potential monetary compensation and failure on psychological indicators of malingering in traumatic brain injury. 332 traumatic brain injury patients were divided into three groups based on incentive to perform poorly on neuropsychological testing: no incentive; limited incentive as provided by State law; high incentive as provided by Federal law. The rate of failure on five well-validated malingering indicators across these groups was examined...
