Espresso coffee is among the most consumed beverages in the world. Recent studies report a protective activity of the coffee beverage against neurodegenerative disorders such as Alzheimer′s disease. Alzheimer′s disease belongs to a group of disorders, called tauopathies, which are characterized by the intraneuronal accumulation of the microtubule-associated protein tau in fibrillar aggregates. In this… Continue reading #Espresso Coffee Mitigates the Aggregation and Condensation of #Alzheimer′s Associated Tau Protein

Opting for olive oil could boost brain healthRegular olive oil consumption associated with 28% lower risk of fatal dementia
oil as part of a Mediterranean dietary pattern has also been shown to help protect against cognitive decline. Tessier cautioned that the research is observational and does not prove that olive oil is the cause of the reduced risk of fatal dementia. Additional studies such as randomized controlled trials would be needed to confirm the effects… Continue reading Opting for olive oil could boost brain healthRegular olive oil consumption associated with 28% lower risk of fatal dementia
Hearing intervention versus health education control to reduce cognitive decline in older adults with hearing loss in the USA (ACHIEVE): a multicentre, randomised controlled trial
Hearing loss is associated with increased cognitive decline and incident dementia in older adults. We aimed to investigate whether a hearing intervention could reduce cognitive decline in cognitively healthy older adults with hearing loss.MethodsThe ACHIEVE study is a multicentre, parallel-group, unmasked, randomised controlled trial of adults aged 70–84 years with untreated hearing loss and without… Continue reading Hearing intervention versus health education control to reduce cognitive decline in older adults with hearing loss in the USA (ACHIEVE): a multicentre, randomised controlled trial
Objectively Measured Visual Impairment and Dementia Prevalence in Older Adults in the US
Importance Estimates of the association between visual impairment (VI) and dementia in the US population are based on self-reported survey data or measures of visual function that are at least 15 years old. Older adults are at high risk of VI and dementia so there is a need for up-to-date national estimates based on objective assessments.Objective To… Continue reading Objectively Measured Visual Impairment and Dementia Prevalence in Older Adults in the US
Cognitive Activity and Onset Age of Incident Alzheimer Disease Dementia
Objective To test the hypothesis that higher level of cognitive activity predicts older age at dementia onset in Alzheimer disease (AD) dementia.Methods As part of a longitudinal cohort study, 1,903 older persons without dementia at enrollment reported their frequency of participation in cognitively stimulating activities. They had annual clinical evaluations to diagnose dementia and AD, and the… Continue reading Cognitive Activity and Onset Age of Incident Alzheimer Disease Dementia
The associations of glycosylated hemoglobin with grey matter volume and depression: Investigating mediating role of grey matter volume
Highlights•This is the first study to investigate the mediation effect of GMV on the association between HbA1c and depression.•Hba1c was negatively associated with GMV, and that association were stronger in prediabetic participants.•Cerebral GMV plays a mediating role on the association “HbA1c-depression”, with a proportions of 6.82%.•Effective control of glycemia can potentially prevent brain abnormality and… Continue reading The associations of glycosylated hemoglobin with grey matter volume and depression: Investigating mediating role of grey matter volume
Partial MCT1 invalidation protects against diet-induced non-alcoholic fatty liver disease and the associated brain dysfunction
Highlights•Diet-induced NAFLD and associated systemic alterations result in behavioural changes and low-grade brain tissue hypoxia.•Brain hypoxia is likely linked to the induced low-grade brain inflammation, as well as cerebrovascular, glial, and metabolic alterations.•Mct1 haploinsufficient mice are protected from NAFLD and detrimental cerebral alterations.•MCT1 is a potential novel therapeutic target for preventing and/or treating NAFLD and the… Continue reading Partial MCT1 invalidation protects against diet-induced non-alcoholic fatty liver disease and the associated brain dysfunction
Elevated C-reactive protein mediates the liver-brain axis: a preliminary study
BackgroundChronic liver diseases of all etiologies exist along a spectrum with varying degrees of hepatic fibrosis. Despite accumulating evidence implying associations between liver fibrosis and cognitive functioning, there is limited research exploring the underlying neurobiological factors and the possible mediating role of inflammation on the liver-brain axis.MethodsUsing data from the UK Biobank, we examined the cross-sectional association… Continue reading Elevated C-reactive protein mediates the liver-brain axis: a preliminary study
Wearable movement-tracking data identify Parkinson’s disease years before clinical diagnosis
Parkinson’s disease is a progressive neurodegenerative movement disorder with a long latent phase and currently no disease-modifying treatments. Reliable predictive biomarkers that could transform efforts to develop neuroprotective treatments remain to be identified. Using UK Biobank, we investigated the predictive value of accelerometry in identifying prodromal Parkinson’s disease in the general population and compared this… Continue reading Wearable movement-tracking data identify Parkinson’s disease years before clinical diagnosis
