Sustained Preservation of Cognition and Prevention of Patient-Reported Symptoms With Hippocampal Avoidance During Whole-Brain Radiation Therapy for Brain Metastases: Final Results of NRG Oncology CC001

Initial report of NRG Oncology CC001, a phase 3 trial of whole-brain radiation therapy plus memantine (WBRT+memantine) with or without hippocampal avoidance (HA), demonstrated neuroprotective effects of HA with a median follow-up of fewer than 8 months. Herein, we report the final results with complete cognition, patient-reported outcomes, and longer-term follow-up exceeding 1 year. Adult patients with brain metastases were randomized to HA-WBRT+memantine or WBRT+memantine. The primary endpoint was time to cognitive function failure, defined as decline using the reliable change index on the Hopkins Verbal Learning Test-Revised (HVLT-R), Controlled Oral Word Association, or the Trail Making Tests (TMT) A and B. Patient-reported symptom burden was assessed using the MD Anderson Symptom Inventory with Brain Tumor Module and EQ-5D-5L. Between July 2015 and March 2018, 518 patients were randomized. The median follow-up for living patients was 12.1 months. The addition of HA to WBRT+memantine prevented cognitive failure (adjusted hazard ratio, 0.74, P=.016) and was associated with less deterioration in TMT-B at 4 months (P=.012) and HVLT-R recognition at 4 (P=.055) and 6 months (P=.011). Longitudinal modeling of imputed data showed better preservation of all HVLT-R domains (P < .005). Patients who received HA-WBRT+Memantine reported less symptom burden at 6 (P < .001 using imputed data) and 12 months (P=.026 using complete-case data; P < .001 using imputed data), less symptom interference at 6 (P=.003 using complete-case data; P=.0016 using imputed data) and 12 months (P=.0027 using complete-case data; P=.0014 using imputed data), and fewer cognitive symptoms over time (P=.043 using imputed data). Treatment arms did not differ significantly in overall survival, intracranial progression-free survival, or toxicity. With median follow-up exceeding 1 year, HA during WBRT+memantine for brain metastases leads to sustained preservation of cognitive function and continued prevention of patient-reported neurologic symptoms, symptom interference, and cognitive symptoms with no difference in survival or toxicity.

Regression-Based Norms for the Hopkins Verbal Learning Test-Revised and the Rey-Osterrieth Complex Figure in a Portuguese Adult Population.

The principal goal of this study was to produce adjusted normative data for European Portuguese native speakers from Portugal on 2 neuropsychological tests widely used to assess learning and memory: the Hopkins Verbal Learning Test-Revised (HVLT-R) and the Rey-Osterrieth Complex Figure Test (ROCF). The study included 300 individuals aged 18-92years (M=50.4, SD=21.2), who had educational backgrounds ranging from 3 to 25years (M=10.4, SD=5.2). Age, education, and sex were significantly associated with HVLT-R and ROCF performance. These demographic variables accounted for 61% of the variance in HVLT-R total recall, 54% in HVLT-R delayed recall, 18% in HVLT-R recognition, 55% in ROCF copy, and 39% in ROCF immediate recall. The normative data are presented as regression-based algorithms to adjust direct and derived test scores for age, education, and sex. This study provides a calculator of normative data derived from the results of the regression models.

Neuropsychological features of delusions in hospitalized older adults with neurocognitive disorders

ABSTRACT Individuals with neurocognitive disorders (NCD) frequently experience psychotic symptoms, such as delusions. Delusions can contribute to other behavior problems, create dangers for patients and caregivers, and contribute to inpatient hospitalization of individuals with NCD. The current study aimed to identify cognitive symptoms associated with the presence of delusions and to differentiate delusion types based on cognitive profiles among hospitalized older adults with NCD. A review of electronic medical records of hospitalized older adults from an inpatient geriatric psychiatry setting yielded 185 patients with a diagnosis of mild or major NCD who had a neuropsychological evaluation during their admission and whose documentation described a clear delusion. We identified a comparison group of 185 patients without delusions well matched for age, education, and sex, and similar in global cognitive status. Exclusion criteria included delirium and history of a psychotic disorder. We first compared the groups’ performances on a dementia battery. Then, cognitive performances of subgroups with specific delusion types (harm, theft, jealousy, and misidentification) were each compared to the remainder of the delusion-positive group. Exploratory analyses revealed that the delusion-positive group had a greater rate of discontinuation on Trails B and performed worse than the delusion-negative group on Trails A, Behavioral Dyscontrol Scale, Semantic Fluency, and Hopkins Verbal Learning Test-Revised (HVLT-R) initial registration. Theft delusions were associated with worse performance on HVLT-R recognition, misidentification delusions were associated with worse performance on Trails B, and harm delusions were associated with worse performance on a verbal generativity test. The presence of delusions in hospitalized older adults with NCD was associated with worse performance on several cognitive tasks with many being suggestive of associated with frontal-subcortical network integrity. Delusions of theft may be a consequence of reduced integrity of medial temporal lobe memory system.

Neurological outcome and memory performance in patients with 10 or more brain metastases treated with frameless linear accelerator (LINAC)-based stereotactic radiosurgery.

To assess the neurocognitive function and neurological toxicity of frameless linear accelerator (LINAC)-based stereotactic radiosurgery (SRS) in patients with 10 or more brain metastases (BM). Forty consecutive adult patients who received SRS for ten or more 10 BM < 3cm in maximum size were evaluated. All plans were generated using a single-isocenter multiple-target (SIMT) SRS technique with doses of 22Gy for lesions < 2cm and 16-18Gy for those ≥ 2cm in size. Survival analyses were estimated by Kaplan-Meier method from the date of SRS. Neurocognitive function using the Hopkins verbal learning test-revised (HVLT-R) and activity of daily living scale (ADLS) were collected prospectively at baseline and at 3,6 and 12-month follow-up. Toxicity was assessed by the National Cancer Institute Common Toxicity Criteria for Adverse Events (Version 5.0). With a median follow-up of 10.8months, 1-year survival and local control rates were 65% and 86%, respectively. Grade 2 or 3 toxicity occurred in eleven patients, being associated with radiological changes suggestive of radiation necrosis in seven patients. Three months after SRS, the mean relative decline was 14.2% for HVLT-R delayed recall, 12.3% for HVLT-R recognition, and 9.8% for HVLT-R total recall. A significant deterioration of HVLT-R scores ranged from 5.5 to 18.7% of patients at different time points. ADLS scores declined over time, but changes were not significant. SRS is an effective and safe approach for patients with 10 or more BM able to maintain the pretreatment neurocognitive function in the majority of patients.

Pretreatment Volume of MRI-Determined White Matter Injury Predicts Neurocognitive Decline After Hippocampal Avoidant Whole-Brain Radiation Therapy for Brain Metastases: Secondary Analysis of NRG Oncology Radiation Therapy Oncology Group 0933

PurposeNRG Oncology's RTOG 0933 demonstrated benefits to memory preservation after hippocampal avoidant whole-brain radiation therapy (HA-WBRT), the avoidance of radiation dose to the hippocampus (using intensity modulated radiation planning and delivery techniques) during WBRT, supporting the hypothesis of hippocampal radiosensitivity and associated memory specificity. However, some patients demonstrated cognitive decline, suggesting mechanisms outside hippocampal radiosensitivity play a role. White matter injury (WMI) has been implicated in radiation therapy–induced neurocognitive decline. This secondary analysis explored the relationship between pretreatment WMI and memory after HA-WBRT. Methods and MaterialsVolumetric analysis of metastatic disease burden and disease-unrelated WMI was conducted on the pretreatment magnetic resonance image. Correlational analyses were performed examining the relationship between pretreatment WMI and Hopkins Verbal Learning Test-Revised (HVLT-R) outcomes at baseline and 4 months after HA-WBRT. ResultsIn the study, 113 patients received HA-WBRT. Of 113 patients, 33 underwent pretreatment and 4-month posttreatment HVLT testing and pretreatment postcontrast volumetric T1 and axial T2/fluid-attenuated inversion recovery magnetic resonance imaging. Correlation was found between larger volumes of pretreatment WMI and decline in HVLT-R recognition (r = 0.54, P < .05), and a correlational trend was observed between larger volume of pretreatment WMI and decline in HVLT-R delayed recall (r = 0.31, P = .08). Patients with higher pretreatment disease burden experienced a greater magnitude of stability or positive shift in HVLT-R recall and delayed recall after HA-WBRT (r = –0.36 and r = –0.36, P < .05), compared to the magnitude of stability or positive shift in those with lesser disease burden. ConclusionsIn patients receiving HA-WBRT for brain metastases, extent of pretreatment WMI predicts posttreatment memory decline, suggesting a mechanism for radiation therapy–induced neurocognitive toxicity independent of hippocampal stem cell radiosensitivity. Stability or improvement in HVLT after HA-WBRT for patients with higher pretreatment intracranial metastatic burden supports the importance of WBRT-induced intracranial control on neurocognition.

Correlations between CSF proteins and spontaneous neuronal activity in Parkinson’s disease

The relationship between cerebrospinal fluid (CSF) proteins and brain function in Parkinson’s disease (PD) is not explained clearly. We investigated the correlations between CSF proteins and spontaneous neuronal activity in PD patients via fractional amplitude of low-frequency fluctuation (fALFF) using the Parkinson’s Progression Markers Initiative database. Twenty-eight PD patients underwent resting-state functional magnetic resonance imaging in “off” status and lumbar puncture within a month. Correlation analyses between CSF proteins and fALFF value in whole brain as well as clinical assessment scores were performed. We found CSF total tau (t-tau) level was negatively correlated with fALFF in posterior cingulate gyrus. And fALFF in posterior cingulate gyrus was positively correlated with Hopkins Verbal Learning Test-Revised recognition discrimination index. Besides, alpha-synuclein (α-syn) level was correlated with fALFF in bilateral inferior frontal gyrus. This study provides evidence that CSF proteins may have a relationship with brain function related to cognitive status in PD patients.

Embedded Performance Validity Tests in the Hopkins Verbal Learning Test-Revised and the Brief Visuospatial Memory Test-Revised: A Replication Study.

Embedded performance validity tests (PVTs) within the Hopkins Verbal Learning Test-Revised (HVLT-R) and Brief Visuospatial Memory Test-Revised (BVMT-R) were recently identified. This study aimed to further validate/replicate these embedded PVTs. Eighty clinically referred veterans who underwent neuropsychological evaluation were included. Validity groups were established by passing/failing 2-3 well-validated PVTs, with 75% (n = 60) classified as valid and 25% (n = 20) noncredible. Fifty-two percent of valid participants were cognitively impaired. HVLT-R Recognition Discrimination (RD) of ≤5 yielded 67% sensitivity/80% specificity for identifying noncredible performance. Removal of seven valid participants with an amnestic profile who produced a false positive, improved specificity to 92%, which replicated the original findings. Replication efforts failed for BVMT-R Percent Retained; however, significant findings for RD were elucidated. Replication efforts were positive for the HVLT-R embedded PVT, corroborating its ability to identify invalid performance in this heterogeneous clinical veteran sample with and without cognitive impairment.

Embedded performance validity tests within the Hopkins Verbal Learning Test – Revised and the Brief Visuospatial Memory Test – Revised

Objective: Various research studies and neuropsychology practice organizations have reiterated the importance of developing embedded performance validity tests (PVTs) to detect potentially invalid neurocognitive test data. This study investigated whether measures within the Hopkins Verbal Learning Test – Revised (HVLT-R) and the Brief Visuospatial Memory Test – Revised (BVMT-R) could accurately classify individuals who fail two or more PVTs during routine clinical assessment.Method: The present sample of 109 United States military veterans (Mean age = 52.4, SD = 13.3), all consisted of clinically referred patients and received a battery of neuropsychological tests. Based on performance validity findings, veterans were assigned to valid (n = 86) or invalid (n = 23) groups. Of the 109 patients in the overall sample, 77 were administered the HLVT-R and 75 were administered the BVMT-R, which were examined for classification accuracy.Results: The HVLT-R Recognition Discrimination Index and the BVMT-R Retention Percentage showed good to adequate discrimination with an area under the curve of .78 and .70, respectively. The HVLT-R Recognition Discrimination Index showed sensitivity of .53 with specificity of .93. The BVMT-R Retention Percentage demonstrated sensitivity of .31 with specificity of .92.Conclusions: When used in conjunction with other PVTs, these new embedded PVTs may be effective in the detection of invalid test data, although they are not intended for use in patients with dementia.
