“…The nature of his mild complicated concussion was consistent with a composite MN-BEST rating of '15'. [34]), but performances on other effort measures were within normal limits. Pre-morbid level of intellect was within the average range (WTAR FSIQ = 91) and is relatively consistent with available WAIS-III intellectual performances.…”

Background/objective: Soldiers of Operations Enduring Freedom (OEF) and Iraqi Freedom (OIF) sustain blast-related mild traumatic brain injury concussion) with alarming regularity. This study discusses factors in addition to concussion, such as co-morbid psychological difficulty (e.g. post-traumatic stress) and symptom validity concerns that may complicate neuropsychological evaluation in the late stage of concussive injury. Case report: The study presents the complexities that accompany neuropsychological evaluation of blast concussion through discussion of three case reports of OEF/OIF personnel. Discussion: The authors emphasize uniform assessment of blast concussion, the importance of determining concussion severity according to acute-injury characteristics and elaborate upon non-concussion-related factors that may impact course of cognitive limitation. The authors conclude with a discussion of the need for future research examining the impact of blast concussion (particularly recurrent concussion) and neuropsychological performance.

“…To control for lack of effort in the neuropsychological assessment, we calculated the Reliable Digit Span (RDS; Greiffenstein et al, 1994) as an embedded performance validity test. The RDS is calculated as the sum of the longest number of digits correctly repeated in the forward and backward condition of the Digit Span test of the Wechsler Adult Intelligence Scale Version III (Von Aster et al, 2006).…”

Negative symptoms can be grouped into the two dimensions of diminished expression and apathy, which have been shown to be dissociable regarding external validators, such as functional outcome. Here, we investigated whether these two dimensions differentially relate to neurocognitive impairment in schizophrenia. 47 patients with schizophrenia or schizoaffective disorder and 33 healthy control participants were subjected to a neurocognitive test battery assessing multiple cognitive domains (processing speed, working memory, verbal fluency, verbal learning and memory, mental planning), which are integrated into a composite cognition score. Negative symptoms in patients were assessed using the Brief Negative Symptom Scale. We found that diminished expression significantly related to neurocognitive impairment, while severity of apathy symptoms was not directly associated with neurocognition. Other assessed clinical variables include chlorpromazine equivalents, positive symptoms, and depressive symptoms and did not influence the results. Our results are in line with a cognitive resource limitation model of diminished expression in schizophrenia and indicate that cognitive remediation therapy might be helpful to ameliorate expressive deficits.

“…RDS was originally developed by Greiffenstein et al [43] and has been shown to be a useful validity marker across a number of studies [22,41,44]. A cut-off score of less than 7 was used.…”

Abstract-Individuals with the same neurological conditions do not necessarily manifest the same behavioral presentation, which suggests differences in resilience and vulnerability among individuals, a concept known as cognitive reserve. This study sought to explore the relationship among cognitive reserve, executive functioning, and health and safety judgment in a sample of older adult inpatients in an extended medical care unit at a Veterans Health Administration hospital. We hypothesized that cognitive reserve, as determined by an estimate of premorbid intellectual ability, would act as a protective factor against poor judgment in older adults with executive dysfunction. Participants included 200 Veterans who completed a comprehensive neuropsychological assessment, including measures of health and safety judgment, executive functioning, global cognitive functioning, and premorbid intellectual ability. After controlling for global cognitive functioning, executive functioning abilities did not have an effect on judgment abilities among those with high estimated intellectual ability. However, executive functioning had a significant effect on judgment abilities among those with low estimated intellectual ability. Our results suggest that intact executive functioning is critical for making appropriate health and safety decisions for patients with lower measured intellectual abilities and provide further support for the cognitive reserve model. Clinical implications are also discussed.
