AbstractBackground: Worldwide, coffee is one of the most popular beverages consumed. Several studies have suggested a protective role of coffee, including reduced risk of Alzheimer's disease (AD). However, there is limited longitudinal data from cohorts of older adults reporting associations of coffee intake with cognitive decline, in distinct domains, and investigating the neuropathological mechanisms underpinning any… Continue reading Higher #Coffee Consumption Is Associated With Slower #Cognitive Decline and Less Cerebral Aβ-Amyloid Accumulation Over 126 Months: Data From the Australian Imaging, Biomarkers, and Lifestyle Study

Glycated Hemoglobin A1c Time in Range and #Dementia in Older Adults With #Diabetes
Key PointsQuestion In older individuals with diabetes, is maintaining stability of glycated hemoglobin A1c levels (HbA1c) in individualized target ranges over time associated with lower risk of Alzheimer disease and related dementias (ADRD)?Findings In this cohort study of 374 021 older veterans with diabetes, greater HbA1c stability, as measured by HbA1c time in range, was associated with a lower risk of… Continue reading Glycated Hemoglobin A1c Time in Range and #Dementia in Older Adults With #Diabetes
Are Blood Tests for #Alzheimer Disease Ready for Prime Time?
This is a transformative time for patients with Alzheimer disease. Alzheimer disease is increasingly viewed as a treatable condition and managed like other major chronic diseases, such as heart disease and cancer. Management of Alzheimer disease includes early diagnosis with molecular confirmation, disease-modifying treatments that are initiated early in the disease course, better risk reduction… Continue reading Are Blood Tests for #Alzheimer Disease Ready for Prime Time?
Older adults at greater risk for #Alzheimer’s disease show stronger associations between sleep #apnea severity in #REM sleep and verbal memory
Obstructive sleep apnea (OSA) increases risk for cognitive decline and Alzheimer’s disease (AD). While the underlying mechanisms remain unclear, hypoxemia during OSA has been implicated in cognitive impairment. OSA during rapid eye movement (REM) sleep is usually more severe than in non-rapid eye movement (NREM) sleep, but the relative effect of oxyhemoglobin desaturation during REM… Continue reading Older adults at greater risk for #Alzheimer’s disease show stronger associations between sleep #apnea severity in #REM sleep and verbal memory
Scanning #ultrasound-mediated memory and functional improvements do not require #amyloid-β reduction
A prevalent view in treating age-dependent disorders including Alzheimer’s disease (AD) is that the underlying amyloid plaque pathology must be targeted for cognitive improvements. In contrast, we report here that repeated scanning ultrasound (SUS) treatment at 1 MHz frequency can ameliorate memory deficits in the APP23 mouse model of AD without reducing amyloid-β (Aβ) burden. Different… Continue reading Scanning #ultrasound-mediated memory and functional improvements do not require #amyloid-β reduction
Summary: A new study explores the molecular connections between Type 2 #diabetes and #Alzheimer’s, supporting the notion of Alzheimer’s as “Type 3 diabetes.”
This study finds that a high-fat diet suppresses a crucial gut protein, Jak3, leading to Alzheimer’s-like brain changes in mice. It underscores the importance of managing diabetes or avoiding it through diet to reduce Alzheimer’s risk.The findings illuminate a potential path from diet through gut inflammation to brain health, offering hope for preventative strategies.Key Facts:Molecular… Continue reading Summary: A new study explores the molecular connections between Type 2 #diabetes and #Alzheimer’s, supporting the notion of Alzheimer’s as “Type 3 diabetes.”
#Sildenafil as a Candidate Drug for #Alzheimer’s Disease: Real-World Patient Data Observation and Mechanistic Observations from Patient-Induced Pluripotent Stem Cell-Derived Neurons
Abstract: Background: Alzheimer’s disease (AD) is a chronic neurodegenerative disease needing effective therapeutics urgently. Sildenafil, one of the approved phosphodiesterase-5 inhibitors, has been implicated as having potential effect in AD. Objective: To investigate the potential therapeutic benefit of sildenafil on AD. Methods: We performed real-world patient data analysis using the MarketScan® Medicare Supplemental and the Clinformatics®… Continue reading #Sildenafil as a Candidate Drug for #Alzheimer’s Disease: Real-World Patient Data Observation and Mechanistic Observations from Patient-Induced Pluripotent Stem Cell-Derived Neurons
#Statins and cognitive decline in patients with #Alzheimer’s and mixed dementia: a longitudinal registry-based cohort study
BackgroundDisturbances in brain cholesterol homeostasis may be involved in the pathogenesis of Alzheimer’s disease (AD). Lipid-lowering medications could interfere with neurodegenerative processes in AD through cholesterol metabolism or other mechanisms.ObjectiveTo explore the association between the use of lipid-lowering medications and cognitive decline over time in a cohort of patients with AD or mixed dementia with… Continue reading #Statins and cognitive decline in patients with #Alzheimer’s and mixed dementia: a longitudinal registry-based cohort study
Clinically apparent #Helicobacter pylori infection and the risk of incident #Alzheimer’s disease: A population-based nested case-control study
INTRODUCTIONOur population-based study assessed whether clinically apparent Helicobacter pylori infection (CAHPI) is associated with the risk of Alzheimer's disease (AD).METHODSWe assembled a population-based cohort of all dementia-free subjects in the United Kingdom's Clinical Practice Research Datalink (UK CPRD), aged ≥50 years (1988–2017). Using a nested case-control approach, we matched each newly developed case of AD with 40… Continue reading Clinically apparent #Helicobacter pylori infection and the risk of incident #Alzheimer’s disease: A population-based nested case-control study
