Objective: To relate neurophysiologic changes after mild/moderate traumatic brain injury to cognitive deficit in a longitudinal diffusion tensor imaging investigation. Methods: Fifty-three patients were scanned an average of 6 days postinjury (range 5 1-14 days). Twenty-three patients were rescanned 1 year later. Thirty-three matched control subjects were recruited. At the time of scanning, participants completed cognitive testing. Tract-Based Spatial Statistics was used to conduct voxel-wise analysis on diffusion changes and to explore regressions between diffusion metrics and cognitive performance. Results: Acutely, increased axial diffusivity drove a fractional anisotropy (FA) increase, while decreased radial diffusivity drove a negative regression between FA and Verbal Letter Fluency across widespread white matter regions, but particularly in the ascending fibers of the corpus callosum. Raised FA is hypothesized to be caused by astrogliosis and compaction of axonal neurofilament, which would also affect cognitive functioning. Chronically, FA was decreased, suggesting myelin sheath disintegration, but still regressed negatively with Verbal Letter Fluency in the anterior forceps. Conclusions: Acute mild/moderate traumatic brain injury is characterized by increased tissue FA, which represents a clear neurobiological link between cognitive dysfunction and white matter injury after mild/moderate injury. © 2014 American Academy of Neurology.

Cognitive functioning can be assessed with performance-based assessments such as neuropsychological tests and with interview-based assessments. Both assessment methods have the potential to assess whether treatments for schizophrenia improve clinically relevant aspects of cognitive impairment. However, little is known about the reliability, validity and treatment responsiveness of interview-based measures, especially in the context of clinical trials. Data from two studies were utilized to assess these features of the Schizophrenia Cognition Rating Scale (SCoRS). One of the studies was a validation study involving 79 patients with schizophrenia assessed at 3 academic research centers in the US. The other study was a 32-site clinical trial conducted in the US and Europe comparing the effects of encenicline, an alpha-7 nicotine agonist, to placebo in 319 patients with schizophrenia. The SCoRS interviewer ratings demonstrated excellent test-retest reliability in several different circumstances, including those that did not involve treatment (ICC > 0.90), and during treatment (ICC >0.80). SCoRS interviewer ratings were related to cognitive performance as measured by the MCCB (r=-0.35), and demonstrated significant sensitivity to treatment with encenicline compared to placebo (P<.001). These data suggest that the SCoRS has potential as a clinically relevant measure in clinical trials aiming to improve cognition in schizophrenia, and may be useful for clinical practice. The weaknesses of the SCoRS include its reliance on informant information, which is not available for some patients, and reduced validity when patient's self-report is the sole information source. © 2014 Elsevier B.V. and ECNP.

Schizophrenia Research: Cognition | Year: 2014
Introduction: Assessment of functional capacity is an intrinsic part of determining the functional relevance of response to treatment of cognitive impairment in schizophrenia. Existing methods are highly and consistently correlated with performance on neuropsychological tests, but most current assessments of functional capacity are still paper and pencil simulations. We developed a computerized virtual reality assessment that contains all of the components of a shopping trip. Methods: We administered the Virtual Reality Functional Capacity Assessment Tool (VRFCAT) to 54 healthy controls and to 51 people with schizophrenia to test its feasibility. Dependent variables for the VRFCAT included time to completion and errors on 12 objectives and the number of times that an individual failed to complete an objective. The MATRICS Consensus Cognitive Battery (MCCB) and a standard functional capacity measure, the UCSD Performance-Based Skills Assessment-Brief (UPSA-B), were administered to the patients with schizophrenia. Results: Patients with schizophrenia performed more poorly than healthy controls on 10/11 of the time variables, as well as 2/12 error scores and 2/12 failed objectives. Pearson correlations for 7 of 15 VRFCAT variables with MCCB composite scores were statistically significant. Conclusion: These results provide support for the possibility of computerized functional capacity assessment, but more substantial studies are required. © 2014 Elsevier Inc.

Background: Weight gain and changes in metabolic indicators associated with some antipsychotics may be related to symptom improvement and thus an unavoidable correlate of clinical benefit. Methods: Data from the CATIE schizophrenia trial comparing the effectiveness of perphenazine, olanzapine, risperidone, quetiapine and ziprasidone in a randomized, double-blind, trial over 18. months were used to evaluate the relationship between percent change in body mass index (BMI) and change in total serum cholesterol and triglycerides with the Positive and Negative Syndrome Scale (PANSS) score. Analysis of covariance for observations at 3. months and a mixed effects model for all observations up to 18. months adjusted for potentially confounding variables were used to examine these associations. Results: In both models, there was a significant association (p=0.001) between change in PANSS total score and percent change in BMI, equating to a 0.28 and 0.21 point decrease in PANSS total score (range 30-210) per 1% increase in BMI respectively. Change in BMI accounted for 3% or less of variance for change in PANSS scores. There was no evidence that the association of symptoms and weight gain differed across medications in spite of substantial differences in weight gain and other metabolic measures. Neither total serum cholesterol nor triglyceride levels displayed a significant association with change in PANSS. Conclusion: The magnitude of the relationship between change in BMI and PANSS was too small to be clinically important, indicating that switching medications to one with less metabolic risk is unlikely to result in meaningful loss of clinical benefit. © 2011 Elsevier B.V.

Marie Skłodowska-Curie, the first woman to win a Nobel Prize and the only person to be awarded the Nobel Prize twice in different scientific disciplines, is an inspiring figure. She discovered two new elements, polonium and radium, and was appointed as the first female professor at the University of Paris, when in most countries women did not yet have the right to vote. She serves as a role model for scholarly and humanitarian endeavors through what she attained in science, and through the hardships she had to overcome and the gender discrimination barriers faced by women scientists of that period, which she had to break. This article is a tribute to Marie Skłodowska-Curie's achievements. Copyright © 2011 Verlag Helvetica Chimica Acta AG, Zürich, Switzerland.

Objective: The Measurement and Treatment Research to Improve Cognition in Schizophrenia (MATRICS) Project produced a battery of tests, the MATRICS Consensus Cognitive Battery (MCCB), designed to assess cognitive treatment effects in clinical trials of patients with schizophrenia. In validation studies, the MCCB demonstrated excellent reliability, minimal practice effects and significant correlations with measures of functional capacity. This study addresses whether the MCCB demonstrates these favorable characteristics when administered in the context of the type of large multi-site industry trial for which it was designed. Methods: In a clinical trial comparing risperidone and lurasidone, 323 clinically-stable outpatients with schizophrenia at 29 sites were assessed with MCCB at screening and a median of 15. days later at baseline. A measure of functional capacity, the UCSD Performance-based Skills Assessment - Brief (UPSA-B) was administered at baseline. Results: All 323 (100%) patients had sufficient data for computing a composite score according to the MCCB criteria. The test-retest reliability of the MCCB composite score was excellent (ICC. = 0.88). The severity of cognitive impairment was T = 24.7 (SD. = 12.1) at screening and T = 26.7 (SD. = 12.4) at baseline. The MCCB composite score demonstrated a large correlation with the UPSA-B composite score (r = 60, df = 304, p< .001). The practice effect on the composite score was small (z = 0.18). Discussion: In the context of a 29-site antipsychotic trial in stable outpatients with schizophrenia, the MCCB is sensitive to cognitive deficits in all domains, demonstrates excellent test-retest reliability and small practice effects, and is strongly correlated with a leading measure of functional capacity. © 2010 Elsevier B.V.

DESCRIPTION (provided by applicant): Schizophrenia is a devastating and costly mental illness with direct and unemployment costs approaching 95 billion per year. Cognitive impairments affect the majority of patients with schizophrenia. These impairments are strongly associated with poor long-term psychosocial outcomes and reflect a large and significant unmet clinical need. FDA approval of new drugs for cognitive impairment in patients with schizophrenia requires pharmaceutical companies to demonstrate notonly improvements on cognitive tests, but also clear evidence that these cognitive changes lead to clinically meaningful improvements in functional capacity. Measures of functional capacity, known as co-primary measures, indicate the degree to which individuals have changed their potential to alter real-world behavior. At present, there are no standard measures of functional capacity, and existing data do not support the recommendation of any single instrument. The Virtual Reality Functional Capacity Assessment Tool (VRFCAT Copyright (c) 2011) is a novel computer based virtual-reality measure of functional capacity that relies on a realistic simulated environment to recreate routine activities of daily living. We designed it initially for use in domestic schizophrenia drug trials and were successful at developing and pilot testing it in the NIMH SBIR Phase 1 project. Findings on VRFCAT's reliability were encouraging and indicated that it may be superior to the most commonly used measure of functional capacity, the UPSA-2. In this Phase 2 SBIR application, we propose to further evaluate and establish the VRFCAT's sensitivity, reliability, validity and practicality, and prepare to commercialize it through NeuroCog Trials' existing sales and operational infrastructure. This application has 5 specific aims: 1) Examine VRFCAT's ability to measure changes in functional capacity by comparing it to the UPSA-2 in patients with schizophrenia and healthy controls; 2) Examine and compare the test-retest reliabilities ofthe VRFCAT and UPSA-2; 3) Determine the association between performance on the VRFCAT and performance on the standard measure of cognition, the MATRICS Consensus Cognitive Battery (MCCB); 4) Examine the relative strength of the relationship of the VRFCAT and the UPSA-2 with a measure of real-world functioning outcomes, the Specific Levels of Functioning (SLOF); 5) Assess the usability and practicality of the VRFCAT for both patients and research staff in multiple clinical trial settings. In Phase 1 we showed the VRFCAT to be a reliable measure. Phase 2 will allow us to further develop and commercialize the VRFCAT. This new and superior measure of functional capacity could improve clinical trials and facilitate approval for drugs to treat cognitive impairmentin patients suffering from schizophrenia. The VRFCAT has the potential to fulfill the FDA's requirement of a reliable co- primary measure, and will help determine which new drugs have a meaningful impact on cognition and on the lives of schizophrenia patients. PUBLIC HEALTH RELEVANCE: Schizophrenia is a serious mental illness that affects approximately three million Americans and costs about 100 billion a year for direct treatment, community services, and lost wages. While the most obvious symptoms such as hallucinations and bizarre beliefs can be minimized with treatment, there is no currently available treatment for the underlying cognitive disturbances such as memory and attention impairment that are the prime cause of functional disability. Because one of the greatest current challenges of drug development in schizophrenia is to find the best tools for measuring changes in cognition and functioning, this research aims to provide the field with a valid measure of changes in functionally relevantcognition.
