Authors: Mydlikowska-Śmigórska A, Śmigórski K, Rymaszewska J Abstract Changes in the olfactory ability are one of early symptoms of developing neurodegenerative diseases, especially Parkinson's disease and Alzheimer's disease. In a healthy population olfactory function is characterized by independence from an intelligence quotient and various cognitive functions, e.g., memory. The peak of the olfactory ability falls between 20 and 40 years of age. In the geriatric population the worsening of the olfactory ability is found. Because of it, the knowledge on differences between the changes associated wi...

With the continued failure of clinical trials of therapies for Alzheimer's disease, largely immunotherapies, that aim to clear amyloid-β, a growing faction of researchers are rejecting the amyloid hypothesis. In that mainstream view of the condition, the accumulation of amyloid-β causes the early stages of Alzheimer's, but in addition to disrupting the function of neurons, it also causes immune cells in the brain to become inflammatory, dysfunctional, and senescent. This in turn sets the stage for the aggregation of tau protein into neurofibrillary tangles, which causes widespread cell death and the much more sev...

Publication date: Available online 18 July 2019Source: Nitric OxideAuthor(s): Xiaoyi Tang, Zhuang Li, Weiwei Zhang, Zhongxiang YaoAbstractAlzheimer's disease (AD) is a typical neurodegenerative disease in central nervous system (CNS). Generally speaking, patients with severe AD are often accompanied with cognitive impairment. Oligodendrocytes (OLs) are myelin-forming cells in CNS, and myelin injury potentially has something to do with the cognitive impairment in AD. Based on the previous experimental studies, it has been recognized that nitric oxide (NO), as a signaling molecule, might have an influence on the axon and mye...

Increased Neuronal Nuclear and Perikaryal Size in the Medial Mamillary Nucleus of Vascular Dementia and Alzheimer's Disease Patients: Relation to Nuclear Estrogen Receptor α. Dement Geriatr Cogn Disord. 2019 Jul 18;:1-7 Authors: Ishunina TA, Bogolepova IN, Swaab DF Abstract BACKGROUND: The hypothalamic medial mamillary (MMN) and the tuberomamillary (TMN) nuclei are important hubs in memory circuits. Previous studies determining the neuronal Golgi complex size showed decreased metabolic activity of the TMN neurons in both Alzhei-mer's disease (AD) and vascular dementia (VD), and no obvious decline...

In this study, we verify the impact of CDIP parameters compliance on total brain volume variance using 86 scans of the same individual acquired on various scanners. Data included planned data collection acquired within the Consortium pour l'identification précoce de la maladie Alzheimer - Québec (CIMA-Q) and Canadian Consortium on Neurodegeneration in Aging (CCNA) studies, as well as opportunistic data collection from various protocols. For images acquired from Philips scanners, lower variance in brain volumes were observed when the stated CDIP resolution was set. For images acquired from GE scanners, lower v...

New research indicates biological differences might be a reason more women are affected by Alzheimer ’s disease than men.  Although the prevailing thought had been Alzheimer’s affects more women because they tend to live longer, scientists this week at the Alzheimer’s Association International Conference in Los Angeles explained that a toxic protein called tau, which destroys nerve cells, s preads more easily through women’s brains than men’s, the Associated Press reports.  It also…

Abstract Identification of tyrosine Fyn kinase inhibitor is recognized as an effective and feasible therapeutic measure in reducing consequences of memory loss disorder Alzheimer's. The present investigation has been attempted with an objective to find out a novel potent inhibitor with similar homological structure to Fyn kinase using structure based in silico screening measure. Such derived structure was compared with natural data base pool and were systematically analyzed. Ligand based interaction was also tested and evaluated. We applied a molecular dynamic simulation technique to validate the stability of the ...
