Aim: To study clinical characteristics of dementia with Lewy bodies (DLB) depending on neuropsychological, neuroimaging and concomitant cerebrovascular changes as well as on the character of disease onset.
Material And Methods: Forty-five patients with DLB (25 men and 20 women, men age 72.9±7.2 years, illness duration 2.9±2.2) were studied. The diagnosis was made according to international criteria (McKeith, et al, 2017). MRI, clinical/neurological examination and psychometric scales were used.
Results And Conclusion: Clinical, neuropsychological and neuroimaging results reveal the heterogeneity of DLB, which remains poorly investigated. An analysis of the clinical picture, cognitive profile, neuropsychiatric changes and MRI results identified three subtypes of DLB course: 1) typical; 2) with early psychotic manifestation; 3) atypical (mixed). This approach may improve the diagnosis of DLB, prognosis of disease course and treatment effectiveness.

Objective: Alzheimer's disease (AD) and dementia with Lewy bodies (DLB) are common neurodegenerative diseases with distinct but overlapping pathogenic mechanisms. The clinical similarities between these diseases often result in high misdiagnosis rates, leading to serious consequences. Peripheral blood mononuclear cells (PBMCs) are easy to collect and can accurately reflect the immune characteristics of both DLB and AD.

Background: Huntington's disease (HD) is an autosomal dominant condition causing severe neurodegeneration in the striatum and the entorhinal cortex (EC). An epigenome wide association study of DNA methylation in HD by our group, identified potential hypomethylation at the PTGDS gene in the striatum. We aimed to validate this result through pyrosequencing, examining the locus in fine detail, and to assess the signal specificity by profiling multiple neurodegenerative diseases.

Here, we investigated the association between miRNAs and nine age-related cerebral pathologies in participants of the ROS/MAP cohorts.
Method: MiRNA sequencing was performed on samples from the dorsolateral prefrontal cortex of 617 brain donors from participants of the ROS/MAP cohorts.
Background: Single-nucleus RNA sequencing (snRNAseq) allows for the dissection of the cell type-specific transcriptional profiles of tissue specimens. In this study, we compared gene expression in multiple brain cell types in brain tissue from Alzheimer disease (AD) cases with no or other co-existing pathologies including Lewy body disease (LBD) and vascular disease (VaD).
Method: We evaluated differential gene expression measured from single nucleus RNA sequencing (snRNAseq) data generated from the hippocampus region tissue donated by 11 BU ADRC participants with neuropathologically confirmed AD with or without a co-existing pathology (AD-only = 3, AD+VaD = 6, AD+LBD = 2).

Background: The Fukushimura (welfare village), located in Toyohashi city, Japan, is a unique complex of various nursing home facilities including dementia homes, Day-care houses, homes for disabled and mentally retarded, and the Fukushimura Hospital. This village is totally managed by private sector, the Sawarabi Medical Cooperative. About 800 elderly people reside in this area.
