Background: Among the myriad of factors modulating quality of life assessments estimated in patients presenting a variety of cognitive impairments, the distinctive and critical influence of diet and exercise cannot be overestimated. Objective: The objective of this study was to review the evidence to confirm the association between these health-endowering agents and cognitive performance in People With Dementia a Read More

Objective: Cognition is a complex trait representing a set of all mental abilities and processes related to knowledge. Although diverse brain regions are involved, most cognitive processes appear to engage cortical regions. The activity of dopaminergic neurons in prefrontal cortex represents a biological substrate underlying cognitive functions. Alzheimer's Disease (AD) is the most frequent dementia associated with cognitive im Read More

Background: Although mood and sleep disturbances are nearly universal among patients with Alzheimer's disease (AD), brain structures involved in non-cognitive processing remain under characterized in terms of AD pathology. Objectives: This study was designed to evaluate hallmarks of AD pathology in the brainstem of the APPswe/PS1dE9 mouse model of familial AD. Methods: Fresh-frozen sections from female, 12 month o Read More

Background: Combining optimized cognitive (Alzheimer's Disease Assessment Scale- Cognitive subscale, ADAS-Cog) and atrophy markers of Alzheimer's disease for tracking progression in clinical trials may provide greater sensitivity than currently used methods, which have yielded negative results in multiple recent trials. Furthermore, it is critical to clarify the relationship among the subcomponents yielded by cognit Read More

Objective: The inferior parietal lobule (IPL) has been implicate in many higher cognitive processes, as visuo-motor transformations, tool use or tool making. In subjects with mild cognitive impairment (MCI) at major risk to develop Alzheimer' Disease (AD) an impairment of subtle visuomotor or praxic abilities is a well-known clinical feature. Enhance of the ratio of EEG alpha3/alpha2 frequency power was detected in subjects with Read More

Background: Cognitive training (CT) is a non-pharmacological intervention based on a set of tasks that reflect specific cognitive functions. CT is aimed at improving cognition in patients with cognitive impairment, though no definitive conclusions have yet been drawn on its efficacy in Alzheimer's disease (AD). Objective: To assess the effectiveness of a CT program designed to improve cognition in AD patients. Method: Read More

Background: The pathological diagnostic criteria for Alzheimer's disease (AD) updated by the National Institute on Aging-Alzheimer's Association (NIA-AA) in 2012 has been widely adopted, but the clinicopathological relevance remained obscure in Chinese population. Objective: This study aims to investigate the correlations between the antemortem clinical cognitive performances and the postmortem neuropathological change Read More

Background: The longitudinal change of neuropsychological tests (NPTs) in treated Alzheimer's disease (AD) is essential to understand the interplay of a therapeutic response from medication and a disease decline due to degenerative processes. The aim of our study is to investigate the annual cognitive progression as measured by commonly used NPTs in treated AD patients and to assess the potential predictors of disease prog Read More

Background: Oxidative stress is one of the causative factors in the pathogenesis of neurodegenerative diseases including mild cognitive impairment (MCI) and dementia. We previously reported that molecular hydrogen (H2) acts as a therapeutic and preventive antioxidant. Objective: We assess the effects of drinking H2-water (water infused with H2) on oxidative stress model mice and subjects with MCI. Methods: Transgenic mic Read More

Background: Accumulating evidence suggests that dietary factors are associated with Alzheimer's disease, cognition, and brain health in older adults. It is however unclear whether inflammation explains this association. Objective: To examine whether an inflammation-related nutrient pattern (INP) was associated with neuroimaging and cognitive measures of brain health. Method: The current cross-sectional study inclu Read More
