OBJECTIVE: To compare outcomes after intracerebral hemorrhage (ICH) from cerebral arteriovenous malformation (AVM) rupture and other causes of ICH. METHODS: We performed a retrospective population-based study using data from the Nationwide Inpatient Sample. We used standard diagnosis codes to identify ICH cases from 2002 to 2011. Our predictor variable was cerebral AVM. Our primary outcomes were inpatient mortality and home discharge. We used logistic regression to compare outcomes between patients with ICH with and without AVM while adjusting for demographics, comorbidities, and hospital characteristics...

OBJECTIVE: To evaluate long-term mortality in patients with acute ischemic stroke (AIS) by exploring the correlation between death and plasma concentrations of copeptin and N-terminal pro-B-type natriuretic peptide (NT-proBNP) in a cohort study. METHODS: In a prospective, multicenter observational study of 4,215 patients with AIS, copeptin and NT-proBNP levels were measured with a standardized method when patients were admitted to hospital. The primary endpoint was all-cause mortality or cardiovascular disease (CVD) mortality within 1 year...

OBJECTIVE: To determine the placebo component of treatment responses in patients with intellectual disability (ID). METHODS: A statistical meta-analysis comparing bias-corrected effect sizes (Hedges g) of drug responses in open-label vs placebo-controlled clinical trials was performed, as these trial types represent different certainty of receiving genuine treatment (100% vs 50%). Studies in fragile X, Down, Prader-Willi, and Williams syndrome published before June 2015 were considered...

OBJECTIVE: To investigate secular trends in the prevalence, incidence, and survival rate of dementia in a Japanese elderly population in a comprehensive manner. METHODS: Five cross-sectional surveys of dementia were conducted among residents of a Japanese community, aged ≥65 years, in 1985, 1992, 1998, 2005, and 2012. We also established 2 cohorts consisting of the residents of this age group without dementia in 1988 (n = 803) and 2002 (n = 1,231), and each was followed for 10 years...

OBJECTIVE: To investigate the relationship between the presence of a circadian body temperature rhythm and behaviorally assessed consciousness levels in patients with disorders of consciousness (DOC; i.e., vegetative state/unresponsive wakefulness syndrome or minimally conscious state). METHODS: In a cross-sectional study, we investigated the presence of circadian temperature rhythms across 6 to 7 days using external skin temperature sensors in 18 patients with DOC...

OBJECTIVE: To investigate the short-term time course risks and benefits of clopidogrel with aspirin in minor ischemic stroke or TIA. METHODS: Data were derived from the Clopidogrel in High-Risk Patients with Acute Nondisabling Cerebrovascular Events (CHANCE) trial. The primary outcome was a new ischemic stroke. Safety outcomes included any bleeding and moderate to severe bleeding. Time course analyses were performed for the outcomes of both stroke and bleeding. RESULTS: A total of 145 (71...

OBJECTIVE: To address whether to restart older patients on anticoagulants or antiplatelet agents in the setting of a chronic subdural hematoma (cSDH). METHODS: This is an update of a previous review (searched until July 2012). Medline, EMBASE, ISI Web of Knowledge, Google Scholar, PLOS, and the Cochrane Register for Systematic Reviews databases were searched from January 2012 to December 2016. Studies included older adults (those over 65 years) experiencing traumatic subdural hematoma or cSDH who were on anticoagulation or antiplatelet agents...

OBJECTIVE: We report a case series of 10 patients with γ-aminobutyric acid (GABA)-transaminase deficiency including a novel therapeutic trial and an expanded phenotype. METHODS: Case ascertainment, literature review, comprehensive evaluations, and long-term treatment with flumazenil. RESULTS: All patients presented with neonatal or early infantile-onset encephalopathy; other features were hypotonia, hypersomnolence, epilepsy, choreoathetosis, and accelerated linear growth...

OBJECTIVE: To evaluate the association between migraine and body composition status as estimated based on body mass index and WHO physical status categories. METHODS: Systematic electronic database searches were conducted for relevant studies. Two independent reviewers performed data extraction and quality appraisal. Odds ratios (OR) and confidence intervals (CI) were pooled using a random effects model. Significant values, weighted effect sizes, and tests of homogeneity of variance were calculated...

OBJECTIVE: Because the d-2-hydroxyglutarate (D2HG) product of mutant isocitrate dehydrogenase 1 (IDH1(mut)) is released by tumor cells into the microenvironment and is structurally similar to the excitatory neurotransmitter glutamate, we sought to determine whether IDH1(mut) increases the risk of seizures in patients with glioma, and whether D2HG increases the electrical activity of neurons. METHODS: Three WHO grade II-IV glioma cohorts from separate institutions (total N = 712) were retrospectively assessed for the presence of preoperative seizures and tumor location, WHO grade, 1p/19q codeletion, and IDH1(mut) status...

OBJECTIVE: To identify regional brain metabolic dysfunctions associated with neuropsychiatric symptoms (NPS) in preclinical Alzheimer disease (AD). METHODS: We stratified 115 cognitively normal individuals into preclinical AD (both amyloid and tau pathologies present), asymptomatic at risk for AD (either amyloid or tau pathology present), or healthy controls (no amyloid or tau pathology present) using [(18)F]florbetapir PET and CSF phosphorylated tau biomarkers...

Matthew R Cavanaugh, Krystel R Huxlin
OBJECTIVE: To assess if visual discrimination training improves performance on visual perimetry tests in chronic stroke patients with visual cortex involvement. METHODS: 24-2 and 10-2 Humphrey visual fields were analyzed for 17 chronic cortically blind stroke patients prior to and following visual discrimination training, as well as in 5 untrained, cortically blind controls. Trained patients practiced direction discrimination, orientation discrimination, or both, at nonoverlapping, blind field locations...

OBJECTIVE: To evaluate whether the axonal protein neurofilament light (NFL) in serum is a sensitive biomarker to detect subtle brain injury or concussion in contact sports athletes. METHODS: Two prospective cohort studies involving (1) 14 Swedish amateur boxers who underwent fluid biomarker assessments at 7-10 days after bout and after 3 months of rest from boxing and (2) 35 Swedish professional hockey players who underwent blood biomarker assessment at 1, 12, 36, and 144 hours after concussion and when the players returned to play were performed...

OBJECTIVE: To compare nonadherence to statins in older black and white adults following an ischemic stroke. METHODS: We studied black and white adults ≥66 years of age with Medicare fee-for-service insurance coverage hospitalized for ischemic stroke from 2007 to 2012 who filled a statin prescription within 30 days following discharge. Nonadherence was defined as a proportion of days covered <80% in the 365 days following hospital discharge. In addition, we evaluated factors associated with nonadherence for white and black participants separately...
