Background: It has been hypothesized that revascularization of stenotic cerebral arteries may improve cognitive outcome by increasing cerebral perfusion. We sought to compare cognitive outcome in patients treated with percutaneous angioplasty and stenting (PTAS) and aggressive medical management (AMM) vs. AMM alone in the SAMMPRIS Trial. Methods: In SAMMPRIS, 451 patients with recent TIA or stroke attributed to 70%-99% intracranial stenosis were randomized to PTAS plus AMM or AMM alone. Patients with stroke as the qualifying event who had a NIHSS indicating aphasia or neglect were excluded from these analyses. Patients with any ischemic stroke, cerebral infarct with temporary signs (CITS), or ICH during follow-up were excluded from subsequent follow-up visit analyses. The Montreal Cognitive Assessment (MoCA) score was used to assess cognition at baseline, 4 months, 12 months, and closeout (mean 3.05 years in AMM group and 3.12 years in PTAS group). Cognitive impairment was defined as MoCA <26. Mean MoCA scores and the percentage of patients with cognitive impairment were compared between treatment groups at each time point using t-tests and Chi-square tests. Differences in MoCA means from baseline to follow-up time points were compared using mixed model repeated measures ANOVA and Tukey-Kramer tests. Results: As shown in the Figure, there were no significant differences between the treatment groups for mean MoCA at any time point. There were significant improvements in mean MoCA from baseline to 4 months, 12 months, and closeout in both groups. The percentage of patients with cognitive impairment in the AMM vs. PTAS groups were not significantly different at baseline (53 vs. 56%), 4 months (38 vs. 44%), 12 months (42 vs. 40%), and closeout (43 vs. 39%). Conclusions: Revascularization did not provide any additional cognitive benefit over AMM alone in SAMMPRIS even after excluding patients who had cerebral infarction or ICH during follow-up.

Background: Revascularization of stenotic cerebral arteries is hypothesized to improve cognition by increasing cerebral perfusion. Aims: We compared cognition impairment among patients treated with percutaneous angioplasty and stenting (PTAS) and aggressive medical management (AMM) versus AMM alone in the Stenting versus Aggressive Medical Therapy for Intracranial Arterial Stenosis (SAMMPRIS) Trial. Methods: In SAMMPRIS, 451 patients with recent transient ischemic attack or stroke attributed to 70-99% intracranial stenosis were randomized to PTAS plus AMM or AMM alone. Patients who had stroke as the qualifying event with National Institutes of Health Stroke Scale indicating aphasia or neglect were excluded from these analyses. Patients with a cerebrovascular event (ischemic stroke, cerebral infarct with temporary signs or intracranial hemorrhage) during follow-up were excluded from follow-up visit analyses. The Montreal Cognitive Assessment (MoCA) score was used to assess cognition impairment at baseline, 4 months, 12 months and closeout. Cognitive impairment was defined as MoCA <26. Mean MoCA scores and the percentage of patients with cognitive impairment were compared between treatment groups at each time point using t tests and chi-square tests. Differences in MoCA mean at baseline and follow-up time points were compared using mixed model repeated measures ANOVA and Tukey-Kramer tests. Results: There were no significant differences between the treatment groups for mean MoCA at any time point. Mean MoCA scores improved in both groups. The percentage of patients with cognitive impairment in the AMM versus PTAS groups was not significantly different at any time point. Conclusions: Revascularization with PTAS showed no improvement in cognitive impairment over AMM alone among patients who did not have recurrent cerebrovascular events during follow-up.

ABSTRACT. Changes in executive function and motor aspects can compromise the prognosis of older adults with mild cognitive impairment (MCI) and favor the evolution to dementia. Objectives: The aim of this study was to investigate the changes in executive function and gait and to determine the association between changes in these variables. Methods: A 32-month longitudinal study was conducted with 40 volunteers: 19 with preserved cognition (PrC), 15 with MCI and 6 with Alzheimer disease (AD). Executive function and gait speed were assessed using the Frontal Assessment Battery, the Clock-Drawing test and the 10-meter walk test. For data analysis, the Pearson product-moment correlation, two-way repeated-measures ANOVA, and chi-square were conducted. Results: After 32 months, an improvement in the executive function was found in all groups (p=0.003). At baseline, gait speed was slower in individuals with MCI and AD compared to those with PrC (p=0.044), that was maintained after the follow-up (p=0.001). There was significant increase in number of steps in all groups (p=0.001). No significant association was found between changes in gait speed and executive function. Conclusions: It should be taken into account that gait deteriorates prior to executive function to plan interventions and health strategies for this population.

OBJECTIVEThere is emerging data that adults with temporal lobe epilepsy (TLE) without a discrete lesion on brain MRI have surgical outcomes comparable to those with hippocampal sclerosis (HS). However, pediatric TLE is different from its adult counterpart. In this study, the authors investigated if the presence of a potentially epileptogenic lesion on presurgical brain MRI influences the long-term seizure outcomes after pediatric temporal lobectomy.METHODSChildren who underwent temporal lobectomy between 2007 and 2015 and had at least 1 year of seizure outcomes data were identified. These were classified into lesional and MRI-negative groups based on whether an epilepsy-protocol brain MRI showed a lesion sufficiently specific to guide surgical decisions. These patients were also categorized into pure TLE and temporal plus epilepsies based on the neurophysiological localization of the seizure-onset zone. Seizure outcomes at each follow-up visit were incorporated into a repeated-measures generalized linear mixed model (GLMM) with MRI status as a grouping variable. Clinical variables were incorporated into GLMM as covariates.RESULTSOne hundred nine patients (44 females) were included, aged 5 to 21 years, and were classified as lesional (73%), MRI negative (27%), pure TLE (56%), and temporal plus (44%). After a mean follow-up of 3.2 years (range 1.2–8.8 years), 66% of the patients were seizure free for ≥ 1 year at last follow-up. GLMM analysis revealed that lesional patients were more likely to be seizure free over the long term compared to MRI-negative patients for the overall cohort (OR 2.58, p < 0.0001) and for temporal plus epilepsies (OR 1.85, p = 0.0052). The effect of MRI lesion was not significant for pure TLE (OR 2.64, p = 0.0635). Concordance of ictal electroencephalography (OR 3.46, p < 0.0001), magnetoencephalography (OR 4.26, p < 0.0001), and later age of seizure onset (OR 1.05, p = 0.0091) were associated with a higher likelihood of seizure freedom. The most common histological findings included cortical dysplasia types 1B and 2A, HS (40% with dual pathology), and tuberous sclerosis.CONCLUSIONSA lesion on presurgical brain MRI is an important determinant of long-term seizure freedom after pediatric temporal lobectomy. Pediatric TLE is heterogeneous regarding etiologies and organization of seizure-onset zones with many patients qualifying for temporal plus nosology. The presence of an MRI lesion determined seizure outcomes in patients with temporal plus epilepsies. However, pure TLE had comparable surgical seizure outcomes for lesional and MRI-negative groups.

Background:Over the last 2 decades rituximab (RTX) has been widely used, albeit off-label, in primary Sjögren’s syndrome (pSS). Several studies reported that B-lymphocyte depletion with RTX is effective in this disease not only by reducing disease activity but also by affecting the inflammation and the lymphoid organization that occur in target tissues. With the recent release of several RTX biosimilars (bRTX) on the market, the demonstration of their interchangeability with RTX originator (oRTX) is required.Objectives:To compare efficacy and safety of oRTX and bRTX in pSS patients in a real-life setting.Methods:Clinical records of pSS patients referring to a tertiary rheumatology clinic were retrospectively evaluated. Patients having received at least 2 courses of either oRTX or bRTX (1000 mg IV infusion, repeated after 2 weeks -1 course- and the course repeated after 24 weeks) with complete data at baseline and after 3, 6, 9 and 12 months of treatment were enrolled. Disease activity was assessed with the EULAR SS disease activity index (ESSDAI) and its clinical version without the biological domain (ClinESSDAI). Patient-reported symptoms were assessed with the EULAR SS Patient Reported Index (ESSPRI).Results:Seven patients that received oRTX and 7 patients that received bRTX were enrolled. Baseline clinical features, including ESSDAI and ESSPRI were similar in the 2 treatment groups. Both compounds significantly reduced ESSDAI and ESSPRI as early as 3 months and no difference between the groups was observed at any time point (Figure 1). Of interest, ESSDAI slowly decreased until month 6 when the most pronounced reduction was observed. Conversely, ESSPRI dropped to its lowest values already at month 3. With regard to safety, at 12 months of follow-up no adverse event was observed in any of the treatment groups.Conclusion:At 12 months of follow-up, oRTX and bRTX display similar efficacy and safety profiles. The improvement of patient reported outcomes is faster than the improvement of disease activity with both compounds. Our data support interchangeability of oRTX and bRTX in pSS.References:[1]Carubbi F et al. Arthritis Res Ther. 2013;15(5):R172[2]Carubbi F et al.

Abstract Background Diminished sensory gating (SG) is a robust finding in psychotic disorders, but studies of early psychosis (EP) are rare. It is unknown whether SG deficit leads to poor neurocognitive, social, and/or real-world functioning. This study aimed to explore the longitudinal relationships between SG and these variables. Methods Seventy-nine EP patients and 88 healthy controls (HCs) were recruited at baseline. Thirty-three and 20 EP patients completed 12-month and 24-month follow-up, respectively. SG was measured using the auditory dual-click (S1 & S2) paradigm and quantified as P50 ratio (S2/S1) and difference (S1-S2). Cognition, real-life functioning, and symptoms were assessed using the MATRICS Consensus Cognitive Battery, Global Functioning: Social (GFS) and Role (GFR), Multnomah Community Ability Scale (MCAS), Awareness of Social Inference Test (TASIT), and the Positive and Negative Syndrome Scale (PANSS). Analysis of variance (ANOVA), chi-square, mixed model, correlation and regression analyses were used for group comparisons and relationships among variables controlling for potential confounding variables. Results In EP patients, P50 ratio (p < 0.05) and difference (p < 0.001) at 24-month showed significant differences compared with that at baseline. At baseline, P50 indices (ratio, S1-S2 difference, S1) were independently associated with GFR in HCs (all p < 0.05); in EP patients, S2 amplitude was independently associated with GFS (p = 0.037). At 12-month and 24-month, P50 indices (ratio, S1, S2) was independently associated with MCAS (all p < 0.05). S1-S2 difference was a trending predictor of future function (GFS or MCAS). Conclusions SG showed progressive reduction in EP patients. P50 indices were related to real-life functioning.

Abstract Background Technological advances have allowed a variety of computerized cognitive training tools to be engineered in ways that are fun and entertaining yet challenging at a level that can maintain motivation and engagement. This revolution has created an opportunity for gerontological scientists to evaluate brain gaming approaches to improve cognitive and everyday function. The purpose of this scoping review is to provide a critical overview of the existing literature on nonimmersive, electronic brain gaming interventions in older adults with mild cognitive impairment or dementia. Research Design and Methods Systematic search was conducted using 7 electronic databases from inception through July 2017. A comprehensive 2-level eligibility process was used to identify studies for inclusion based on PRISMA guidelines. Results Seventeen studies met eligibility criteria. Majority of the studies were randomized controlled trials (n = 13) and incorporated an active control (n = 9). Intervention doses ranged from 4 to 24 weeks in duration with an average of 8.4 (±5.1 standard deviation [SD]) weeks. Session durations ranged from 30 to 100 min with an average of 54 (±25 SD) minutes. Nearly half of studies included a follow-up, ranging from 3 months to 5 years (n = 8). For most studies, brain gaming improved at least one cognitive outcome (n = 12); only one study reported improvement in activities of daily living. Discussion and Implications This scoping review conveys the breadth of an emerging research field, which will help guide future research to develop standards and recommendations for brain gaming interventions which are currently lacking.

ABSTRACTBackground: Delirium is a risk factor for long-term cognitive impairment and dementia. Yet, the nature of these cognitive deficits is unknown as is the extent to which the persistence of delirium symptoms and presence of depression at follow-up may account for the association between delirium and cognitive impairment at follow-up. We hypothesized that inattention, as an important sign of persistent delirium and/or depression, is an important feature of the cognitive profile three months after hospital discharge of patients who experienced in-hosptial delirium.Methods: This was a prospective cohort study. Fifty-three patients aged 75 years and older were admitted for surgical repair of acute hip fracture. Before the surgery, baseline characteristics, depressive symptomatology, and global cognitive performance were documented. The presence of delirium was assessed daily during hospital admission and three months after hospital discharge when patients underwent neuropsychological assessment.Results: Of 27 patients with in-hospital delirium, 5 were still delirious after three months. Patients with in-hospital delirium (but free of delirium at follow-up) showed poorer performance than patients without in-hospital delirium on tests of global cognition and episodic memory, even after adjustment for age, gender, and baseline cognitive impairment. In contrast, no differences were found on tests of attention. Patients with in-hospital delirium showed an increase of depressive symptoms after three months. However, delirium remained associated with poor performance on a range of neuropsychological tests among patients with few or no signs of depression at follow-up.Conclusion: Elderly hip fracture patients with in-hospital delirium experience impairments in global cognition and episodic memory three months after hospital discharge. Our results suggest that inattention, as a cardinal sign of persistent delirium or depressive symptomatology at follow-up, cannot fully account for the poor cognitive outcome associated with delirium.

BackgroundPrevious cross-sectional studies report that cognitive impairment is associated with poor psychosocial functioning in euthymic bipolar patients. There is a lack of long-term studies to determine the course of cognitive impairment and its impact on functional outcome.MethodA total of 54 subjects were assessed at baseline and 6 years later; 28 had DSM-IV TR bipolar I or II disorder (recruited, at baseline, from a Lithium Clinic Program) and 26 were healthy matched controls. They were all assessed with a cognitive battery tapping into the main cognitive domains (executive function, attention, processing speed, verbal memory and visual memory) twice over a 6-year follow-up period. All patients were euthymic (Hamilton Rating Scale for Depression score lower than 8 and Young mania rating scale score lower than 6) for at least 3 months before both evaluations. At the end of follow-up, psychosocial functioning was also evaluated by means of the Functioning Assessment Short Test.ResultsRepeated-measures multivariate analysis of covariance showed that there were main effects of group in the executive domain, in the inhibition domain, in the processing speed domain, and in the verbal memory domain (p<0.04). Among the clinical factors, only longer illness duration was significantly related to slow processing (p=0.01), whereas strong relationships were observed between impoverished cognition along time and poorer psychosocial functioning (p<0.05).ConclusionsExecutive functioning, inhibition, processing speed and verbal memory were impaired in euthymic bipolar out-patients. Although cognitive deficits remained stable on average throughout the follow-up, they had enduring negative effects on psychosocial adaptation of patients.

AbstractPurposeWhite matter fibre development in childhood involves dynamic changes to microstructural organisation driven by increasing axon diameter, density, and myelination. However, there is a lack of longitudinal studies that have quantified advanced diffusion metrics to identify regions of accelerated fibre maturation, particularly across the early pubertal period. We applied a novel longitudinal fixel-based analysis (FBA) framework, in order to estimate microscopic and macroscopic white matter changes over time.MethodsDiffusion-weighted imaging (DWI) data were acquired for 59 typically developing children (27 female) aged 9 – 13 years at two time-points approximately 16 months apart (time-point 1: 10.4 ± 0.4 years, time-point 2: 11.7 ± 0.5 years). Whole brain FBA was performed using the connectivity-based fixel enhancement method, to assess longitudinal changes in fibre microscopic density and macroscopic morphological measures, and how these changes are affected by sex, pubertal stage, and pubertal progression. Follow-up analyses were performed in sub-regions of the corpus callosum to confirm the main findings using a Bayesian repeated measures approach.ResultsThere was a statistically significant increase in fibre density over time localised to medial and posterior commissural and association fibres, including the forceps major and bilateral superior longitudinal fasciculus. Increases in fibre cross-section were substantially more widespread. The rate of fibre development was not associated with age or sex. In addition, there was no significant relationship between pubertal stage or progression and longitudinal fibre development over time. Follow-up Bayesian analyses were performed to confirm the findings, which supported the null effect of the longitudinal pubertal comparison.ConclusionUsing a novel longitudinal fixel-based analysis framework, we demonstrate that white matter fibre density and fibre cross-section increased within a 16-month scan rescan period in specific regions. The observed increases might reflect increasing axonal diameter or axon count. Pubertal stage or progression did not influence the rate of fibre development in the early stages of puberty. Future work should focus on quantifying these measures across a wider age range to capture the full spectrum of fibre development across the pubertal period.
