Association of Loneliness With 10-Year Dementia Risk and Early Markers of Vulnerability for Neurocognitive Decline

Background and Objective: Loneliness is common and its prevalence is rising. The relationship of loneliness with subsequent dementia and the early preclinical course of Alzheimer disease and related dementia (ADRD) remains unclear. Thus, the primary objective of this study was to determine the association of loneliness with 10-year all-cause dementia risk and early cognitive and… Continue reading Association of Loneliness With 10-Year Dementia Risk and Early Markers of Vulnerability for Neurocognitive Decline

Association of the Gut Microbiota With Cognitive Function in Midlife

Question Is the gut microbiota associated with cognitive function? Findings In this cross-sectional study, β-diversity, a measure of gut microbial community composition, was statistically significantly associated with all measures of cognitive function. Several specific genera were also significantly associated with 1 or more measures of cognitive function after adjustment for multiple comparisons. Meaning These results… Continue reading Association of the Gut Microbiota With Cognitive Function in Midlife

Chronic pain precedes disrupted eating behavior in low-back pain patients

Chronic pain is associated with anhedonia and decreased motivation. These behavioral alterations have been linked to alterations in the limbic brain and could explain the increased risk for obesity in pain patients. The mechanism of these behavioral changes and how they set in in relation to the development of chronic pain remain however poorly understood.… Continue reading Chronic pain precedes disrupted eating behavior in low-back pain patients

Trends in Use of Melatonin Supplements Among US Adults, 1999-2018

Exogenous supplementation of melatonin, one of the key hormones governing circadian rhythm , is indicated for treatment of circadian rhythm sleep disorders1 and, despite insufficient evidence,2 is widely used as an over-the-counter sleep aid. Evidence of antioxidant and anti-inflammatory properties of melatonin3 has prompted investigation of its therapeutic value in multiple diseases.4 Although melatonin is… Continue reading Trends in Use of Melatonin Supplements Among US Adults, 1999-2018

Intake of Flavonoids and Flavonoid-Rich Foods, and Mortality Risk Among Individuals With Parkinson Disease: A Prospective Cohort Study

AbstractBackground and objectives: Although flavonoids have the potential to exert neuroprotective benefits, evidence of their role in improving survival rates among individuals with Parkinson disease (PD) remains lacking. We aimed to prospectively study the association between pre- and post-diagnosis flavonoid intakes and risk of mortality among individuals with PD identified from two large ongoing cohorts… Continue reading Intake of Flavonoids and Flavonoid-Rich Foods, and Mortality Risk Among Individuals With Parkinson Disease: A Prospective Cohort Study

Evaluation of Adiposity and Cognitive Function in Adults

Excess adipose tissue increases other cardiovascular risk factors, which may be associated with vascular brain injury and cognitive impairment. However, the extent to which the amount and distribution of adipose tissue may be associated with lower cognitive scores, independent of its association with cardiovascular risk factors, is not well characterized. Objective To investigate the association… Continue reading Evaluation of Adiposity and Cognitive Function in Adults

Air quality improvement and cognitive decline in community-dwelling older women in the United States: A longitudinal cohort study

Late-life exposure to ambient air pollution is a modifiable risk factor for dementia, but epidemiological studies have shown inconsistent evidence for cognitive decline. Air quality (AQ) improvement has been associated with improved cardiopulmonary health and decreased mortality, but to the best of our knowledge, no studies have examined the association with cognitive function. We examined… Continue reading Air quality improvement and cognitive decline in community-dwelling older women in the United States: A longitudinal cohort study

Intranasal ketamine for acute cluster headache attacks—Results from a proof-of-concept open-label trial

ObjectiveTo investigate the safety and efficacy of intranasal ketamine for the treatment of a single cluster headache (CH) attack. BackgroundAcute treatment options for patients with CH who have an insufficient response to oxygen and triptans are limited. Intranasal ketamine has anecdotally been successful in treating a CH attack. MethodsWe conducted an open-label pilot study enrolling… Continue reading Intranasal ketamine for acute cluster headache attacks—Results from a proof-of-concept open-label trial

Neurophysiological and Brain Structural Markers of Cognitive Frailty Differ from Alzheimer’s Disease

With increasing life span and prevalence of dementia, it is important to understand the mechanisms of cognitive aging. Here, we focus on a subgroup of the population we term “cognitively frail,” defined by reduced cognitive function in the absence of subjective memory complaints, or a clinical diagnosis of dementia. Cognitive frailty is distinct from cognitive… Continue reading Neurophysiological and Brain Structural Markers of Cognitive Frailty Differ from Alzheimer’s Disease
