AbstractAlzheimer ’s disease (AD) is a neurodegenerative disease, known as the most common form of dementia. In AD onset, abnormal rRNA expression has been reported to be linked in pathogenesis. Although region-specific expression patterns have previously been reported in AD, it is not until recently that the cereb ellum has come under the spotlight. Specifically, it is unclear whether DNA methylation is the mechanism involved in rRNA expression regulation in AD. Hence, we sought to explore the rDNA methylation pattern of two different brain regions – auditory cortex and cerebellum – from AD and age-/sex-...

ConclusionMultimodal analysis conducted with various image data from PiB-PET/MRI scans showed differences in regional CBF, cortical volume, and neuronal networks in different regions, indicating that pathophysiologic and functional changes in the AD brain can be observed from various aspects of neurophysiologic parameters. Application of multimodal brain images using PET/MRI would be ideal for investigating pathophysiologic changes in patients with dementia and other neurodegenerative diseases.

CONCLUSIONS: WM pathology is strongly associated with impaired processing speed, and our results indicate that these impairments arise from WMH in the temporal and parieto-occipital regions. In MCI and AD patients with temporal WMH, processing speed impairments are especially prominent. The results of this study increase our knowledge of cognitive repercussions stemming from temporal and/or parieto-occipital WM pathology in healthy and pathological aging.

Conclusions: In this study, we observed in middle- and old-aged individuals with neither dementia nor alcohol-related disorders that moderate lifetime alcohol intake was associated with lower cerebral AB deposition compared to a lifetime history of not drinking. Moderate lifetime alcohol intake may have a beneficial influence on AD by reducing pathological amyloid deposition rather than amyloid-independent neurodegeneration or cerebrovascular injury. The Study in Context: Report: 35% of worldwide dementia cases could be prevented by modifying these 9 modifiable risk factors Study: Drinking up to 5–8 glasses of wine...

As the population ages, the incidence of chronic diseases such as dementia increases. Dementia with Lewy bodies (DLB) is one of the most common dementias after Alzheimer's Disease (AD), and it is characterized clinically by a tetrad consisting of visual hallucinations, spontaneous parkinsonism, REM sleep behavior disorders and dementia [1]. The diagnosis of DLB is challenging. Despite the validated diagnostic criteria, only one in three cases is correctly identified. These criteria have a low sensitivity of 32%, while its specificity has been reported in 95% when its diagnostic accuracy is compared to autopsy [1].
