Despite the extensive study of predictors of cognitive decline in older age, a key uncertainty is how much these predictors explain both the intercept and age- and non-age-related change in cognitive functioning (CF). We examined the contribution of a broad range of life course determinants to CF trajectories. Data came from 7,068 participants in the… Continue reading Predictors of cognitive functioning trajectories among older Americans: A new investigation covering 20 years of age- and non-age-related cognitive change

Race Differences in the Association Between Sleep Medication Use and Risk of Dementia
Abstract: Background:The effect of sleep medications on cognition in older adults is controversial, possibly dependent upon sleep quality, and may differ by race. Objective:To determine the longitudinal association between sleep medication use and incident dementia over 15 years, and to explore whether the association is independent of nighttime sleep disturbances and if it differs by race.… Continue reading Race Differences in the Association Between Sleep Medication Use and Risk of Dementia
The reversible impairment of behavioral variant frontotemporal brain sagging syndrome: Challenges and opportunities
Due to loss of brain buoyancy, spontaneous spinal cerebrospinal fluid (CSF) leaks cause orthostatic headaches but also can cause symptoms indistinguishable from behavioral variant frontotemporal dementia (bvFTD) due to severe brain sagging (including the frontal and temporal lobes), as visualized on brain magnetic resonance imaging. However, the detection of these CSF leaks may require specialized… Continue reading The reversible impairment of behavioral variant frontotemporal brain sagging syndrome: Challenges and opportunities
Premature Cardiovascular Disease and Brain Health in Midlife: The CARDIA Study
Objectives: To understand the role of premature (defined as ≤ 60 years) CVD in brain health earlier in life, we examined the association of premature CVD with midlife cognition and white matter health.Methods: We studied a prospective cohort in the Coronary Artery Risk Development in Young Adults study, who were 18-30 years at baseline (1985-86) and followed… Continue reading Premature Cardiovascular Disease and Brain Health in Midlife: The CARDIA Study
Diagnosis, Workup, Risk Reduction of Transient Ischemic Attack in the Emergency Department Setting: A Scientific Statement From the American Heart Association
At least 240 000 individuals experience a transient ischemic attack each year in the United States. Transient ischemic attack is a strong predictor of subsequent stroke. The 90-day stroke risk after transient ischemic attack can be as high as 17.8%, with almost half occurring within 2 days of the index event. Diagnosing transient ischemic attack… Continue reading Diagnosis, Workup, Risk Reduction of Transient Ischemic Attack in the Emergency Department Setting: A Scientific Statement From the American Heart Association
Intranasal delivery of full-length anti-Nogo-A antibody: A potential alternative route for therapeutic antibodies to central nervous system targets
Antibody delivery to the CNS remains a huge hurdle for the clinical application of antibodies targeting a CNS antigen. The blood–brain barrier and blood–CSF barrier restrict access of therapeutic antibodies to their CNS targets in a major way. The very high amounts of therapeutic antibodies that are administered systemically in recent clinical trials to reach… Continue reading Intranasal delivery of full-length anti-Nogo-A antibody: A potential alternative route for therapeutic antibodies to central nervous system targets
Social isolation and 9-year dementia risk in community-dwelling Medicare beneficiaries in the United States
BackgroundSocial isolation can influence whether older adults develop dementia. We examine the association between social isolation and incident dementia among older adults in a nationally representative sample of community dwelling older adults in the United States (U.S.). We also investigate whether this association varies by race and ethnicity.MethodsData (N = 5022) come from the National Health and… Continue reading Social isolation and 9-year dementia risk in community-dwelling Medicare beneficiaries in the United States
The gut microbiota in multiple sclerosis varies with disease activity
Multiple sclerosis is a chronic immune-mediated disease of the brain and spinal cord resulting in physical and cognitive impairment in young adults. It is hypothesized that a disrupted bacterial and viral gut microbiota is a part of the pathogenesis mediating disease impact through an altered gut microbiota-brain axis. The aim of this study is to… Continue reading The gut microbiota in multiple sclerosis varies with disease activity
Associations of serum zinc, copper, and selenium with sleep disorders in the American adults: Data from NHANES 2011–2016
BackgroundEven though various studies have been conducted to investigate the relationship between trace metals and sleep, few epidemiological studies have evaluated the relationship between trace metals and sleep disorders in American adults.ObjectiveThis study intended to evaluate the associations of serum zinc (Zn), copper (Cu), selenium (Se), Zn/Cu, Zn/Se, and Cu/Se ratios with sleep disorders in… Continue reading Associations of serum zinc, copper, and selenium with sleep disorders in the American adults: Data from NHANES 2011–2016
