Context: While a great deal of interest has been accorded to the cognitive effects of n-3 long-chain polyunsaturated fatty acids (LC PUFAs), there is a need for systematic review data that assess this outcome across the lifespan, accounting for population differences and highlighting methodological limitations of extant studies.

Objective: This systematic review addresses the effects of n-3s on human cognition and provides an overview on the current state of research and recommendations for future efforts.

Data Sources: Based on a thorough review of highly powered articles from PubMed (MEDLINE), Web of Science, and ProQuest Central, the authors evaluated articles published between 2000 and 2020 assessing LC PUFA status on cognition as a primary outcome measure.

Introduction: Retinal imaging is a non-invasive tool to study both retinal vasculature and neurodegeneration. In this exploratory retinal curcumin-fluorescence imaging (RFI) study, we sought to determine whether retinal vascular features combined with retinal amyloid burden correlate with the neurocognitive status.

Methods: We used quantitative RFI in a cohort of patients with cognitive impairment to automatically compute retinal amyloid burden.

Alzheimer's disease (AD) and type 2 diabetes mellitus (T2DM) share many common features including inflammation, oxidative stress and neuronal degeneration. Insulin resistance (IR) appears to be a common path in these pathological processes. IR is an early pathogenic event in AD, which leads to augmentation of hyperphosphorylated tau and Amyloid beta (Aβ).

Article Synopsis
  • A study investigated retinal amyloid beta levels in 34 patients with cognitive decline using a special imaging technique, finding a link between retinal amyloid and brain changes.
  • Results showed that higher retinal amyloid levels were associated with lower hippocampal volume and poorer cognitive scores, particularly in individuals with mild cognitive impairment and Alzheimer's disease.
  • The authors concluded that this retinal imaging method could help predict brain health, and future research should explore its use as an early biomarker for Alzheimer's disease.

Dementia is the fastest growing epidemic in the developed nations, and if not curtailed, it will single handedly collapse our health care system. The prevalence of dementia is 1 in 10 individuals older than 65 years and increases to 50% of all individuals older than 85 years. The prevalence of Alzheimer's dementia (AD), the most common form of dementia, has been increasing rapidly and is projected to reach 16 million individuals by the year 2050.

Background: Little is known about how prevalent dementia rates among patients with stroke have evolved over the last decade or how this relationship varies by gender, race ethnicity, stroke type, or dementia type. We assessed time trends and demographic predictors of coexisting dementia in a large cohort of patients hospitalized for stroke.

Materials And Methods: Patient admission data between 1999 and 2012 were sourced from the National Inpatient Sample.

Background And Purpose: Whether changes in leisure-time physical activity (LTPA) over time are associated with lower risk of stroke is not well established. We examined the association between changes in self-reported LTPA 10 years apart, with risk of incident stroke in the CTS (California Teachers Study). We hypothesized that the risk of stroke would be lowest among those who remained active.

Parkinson's disease (PD) is the second most common neurodegenerative disorder. Although the precise pathogenetic mechanisms of PD remain undetermined, there appears to be both genetic and environmental factors that contribute to the risk of developing PD. With regard to environmental risk factors, there has been significant interest related to the role of diet, nutrition, and nutrients on the onset and progression of PD.

Background: Prior studies show an increased risk of ischemic stroke (IS) after myocardial infarction; however, there is limited evidence on long-term risk and whether it is directly related to cardiac injury. We hypothesized that the risk of IS after acute coronary syndrome is significantly higher if there is evidence of cardiac injury, such as ST-segment elevation myocardial infarction (STEMI) or non-STEMI, than when there is no evidence of cardiac injury, such as in unstable angina.

Methods And Results: Administrative claims data were obtained from all emergency department encounters and hospitalizations at California's nonfederal acute care hospitals between 2008 and 2011.

Background/aim: To date, few studies have cross-examined the relationship between diabetes mellitus (DM) and dementia nationally. There is also a lack of evidence regarding dementia subtypes and how this relationship changes among older individuals. The objective was to better delineate this relationship and influence of multiple comorbidities using a nationwide sample.

Symptomatic intracerebral hemorrhage (sICH) occurs in up to 7% of stroke patients treated with thrombolytic therapy. There are limited data on the effectiveness of the reversal agents used for intravenous tissue plasminogen activator related intracranial bleeds. We report a patient with sICH following intravenous thrombolysis whose intracerebral hemorrhage continued to expand despite treatment with platelets and cryoprecipitate, needing recombinant factor VIIa use for stabilization before surgical evacuation.

Background: The CHADS2 score predicts stroke risk in patients with atrial fibrillation. Although strokes caused by atrial fibrillation carry the highest mortality when compared with other etiologies, it is not known whether the CHADS2 score predicts stroke-related mortality in patients with atrial fibrillation. We hypothesized that higher CHADS2 scores would be associated with higher stroke-related in-hospital mortality.

Women's empowerment has been attempted through a number of different fields including the realms of politics, finance, and education, yet none of these domains are as promising as health care. Here we review preliminary work in this domain and introduce a model for women's empowerment through involvement in health care, titled the "women's health care empowerment model." Principles upon which our model is built include: acknowledging the appropriate definition of empowerment within the cultural context, creating a women's network for communication, integrating local culture and tradition into training women, and increasing the capability of women to care for their children and other women.

Background: Dementia with Lewy bodies (DLB) is characterized neuropathologically by brainstem and cortical Lewy bodies and Lewy neurites, neuronal loss in brainstem nuclei, and Alzheimer disease (AD) pathology. Previous studies have suggested that spongiform change in the entorhinal cortex may also be a pathologic feature; however, this change has not been well characterized.

Design/method: An autopsy series of 40 subjects with DLB and 40 subjects with AD were matched on age, sex, and last Mini Mental State Examination before death.
