Pro Soccer Players More Likely to Develop Dementia: Study

MONDAY, Oct. 21, 2019 -- Former professional soccer players have a significantly increased risk of death from brain diseases such as Alzheimer's and Parkinson's, a new study finds. Former soccer players were about 3.5 times more likely to die of...

AbstractPurpose of ReviewWe summarize structural (s)MRI findings of gray matter (GM) atrophy related to cognitive impairment in Alzheimer ’s disease (AD) and Parkinson’s disease (PD) in light of new analytical approaches and recent longitudinal studies results.Recent FindingsThe hippocampus-to-cortex ratio seems to be the best sMRI biomarker to discriminate between various AD subtypes, following the spatial distribution of tau pathology, and predict rate of cognitive decline. PD is clinically far more variable than AD, with heterogeneous underlying brain pathology. Novel multivariate approaches have been used t...

Abstract Chronic neuroinflammation is a common feature of the pathogenic mechanisms involved in various neurodegenerative age-associated disorders, such as Alzheimer's disease, multiple sclerosis, Parkinson's disease, and dementia. In particular, persistent low-grade inflammation may disrupt the brain endothelial barrier and cause a significant increase of pro-inflammatory cytokines and immune cells into the cerebral tissue that, in turn, leads to microglia dysfunction and lose of neuroprotective properties. Nowadays, growing evidence highlights a strong association between persistent peripheral inflammation, as w...

Abstract BACKGROUND: We investigated the structural changes associated with Alzheimer's disease, dementia with Lewy bodies and Parkinson disease dementia by means of cortical thickness analysis. METHODS: Two hundred and forty-five participants: 76 Alzheimer's disease, 65 dementia with Lewy bodies, 29 Parkinson disease dementia and 76 cognitively normal controls underwent 3-T T1-weighted magnetic resonance imaging and clinical and cognitive assessments. We implemented FreeSurfer to obtain cortical thickness estimates to contrast patterns of cortical thinning across groups and their clinical correlates. RE...

Abstract Neurodegenerative diseases (NDs) are age-dependent; among them, Alzheimer's disease (AD) and Parkinson's disease (PD) are the most frequent. Similarly, cerebrovascular damage can induce the development of vascular-related disorders that share common features with AD and PD, respectively, named vascular dementia (VD) and vascular parkinsonism (VP). To date, ND diagnosis is mainly clinical; therefore, since these disorders show similar symptoms, their correct discrimination may be difficult. We detected 23 ND-associated microRNAs (miRNAs) by literature mining and investigated their serum expression in a coh...

AbstractOver the last two decades, a number of studies have underlined the importance of lysosomal ‐based degradative pathways in maintaining the homeostasis of post‐mitotic cells, and revealed the remarkable contribution of a functional autophagic machinery in the promotion of longevity. In contrast, defects in the clearance of organelles and aberrant protein aggregates have been linked to a ccelerated neuronal loss and neurological dysfunction. Several neurodegenerative disorders, among which Alzheimer disease (AD), Frontotemporal dementia (FTD) and Amyotrophic Lateral Sclerosis (ALS) to name a few, are associated wi...

This study investigated the possibility of significant interactions between these molecules that are involved in the late‐stage of Alzheimer's disease (AD), Parkinson disease (PD), Parkinson disease dementia, dementia with Lewy bodies, and controls using ELISA assays, autoradiography , and mRNA in situ hybridization assay. Interestingly, lower DNA/RNA oxidative adducts levels in the caudate and putamen of diseased brains were observed with the exception of an increased DNA oxidative product in the caudate of AD brains. Similar changes were found for dopamine concentration and ve sicular monoamine transporter 2 densities....

In this study, we hypothesized that moderately and chronically reducing ACh could attenuate the deleterious effects of aging on NMJs and skeletal muscles. To test this hypothesis, we analyzed NMJs and muscle fibers from heterozygous transgenic mice with reduced expression of the vesicular ACh transporter (VAChT), VKDHet mice, which present with approximately 30% less synaptic ACh compared to control mice. Because ACh is constitutively decreased in VKDHet, we first analyzed developing NMJs and muscle fibers. We found no obvious morphological or molecular differences between NMJs and muscle fibers of VKDHet and contro...

In this study, the enhanced mice live somewhat longer than their unmodified peers, though not as much longer as is the case for the application of telomerase gene therapy. The mice do also exhibit reduced cancer risk, however. The scientists here class telomere shortening as a cause of aging, which is not a point universally agreed upon. Reductions in average telomere length in tissues looks much more like a downstream consequence of reduced stem cell activity than an independent mechanism. Researchers obtain the first mice born with hyper-long telomeres and show that it is possible to extend life without any geneti...

This study aimed to verify findings in cerebrospinal fluid (CSF) samples of Alzheimer's disease (AD) and Parkinson's disease (PD) subjects from the network of the European, Innovative Medicines Initiative–funded project AETIONOMY.MethodsA total of 227 samples from the studies/centres AETIONOMY, ICEBERG, and IDIBAPS were used to analyse 21 selected immunity biomarkers in CSF. Results were compared to data of an independent cohort of 399 subjects previously published.ResultsImmunity markers were predominantly and reproducibly associated with pathological levels of tau isoforms, but also with amyloid levels, aging, sex,...
