Identifying the Role of Oligodendrocyte Genes in the Diagnosis of Alzheimer's Disease through Machine Learning and Bioinformatics Analysis
Chen Y, Li C, Yao Y and Shang Y
Due to the heterogeneity of Alzheimer's disease (AD), the underlying pathogenic mechanisms have not been fully elucidated. Oligodendrocyte (OL) damage and myelin degeneration are prevalent features of AD pathology. When oligodendrocytes are subjected to amyloid-beta (Aβ) toxicity, this damage compromises the structural integrity of myelin and results in a reduction of myelin-associated proteins. Consequently, the impairment of myelin integrity leads to a slowdown or cessation of nerve signal transmission, ultimately contributing to cognitive dysfunction and the progression of AD. Consequently, elucidating the relationship between oligodendrocytes and AD from the perspective of oligodendrocytes is instrumental in advancing our understanding of the pathogenesis of AD.
Associations between Physical Performance Tests with Cognitive Changes: The Moderating Effect of Cognitive Status
Lim ZH, Yu J, Kuparasundram S, Mahendran R and Ng TKS
Age-related cognitive decline has been linked with risk factors, including physical performance. Prior studies investigating such associations were typically conducted in clinical settings within Western populations with a frequent focus on late neurocognitive diagnostic stages (i.e., Alzheimer's disease), reducing their generalizability to the Asian population and early neurocognitive stages. To address these knowledge gaps, our study investigated longitudinal associations between physical performance measures at baseline and cognitive change in global cognition, executive functioning (EF) based and non-executive functioning (non- EF) based cognitive domains within the Singaporean population. The moderating role of early neurocognitive status, namely mild cognitive impairment (MCI) and cognitively normal (CN), was also examined.
Capgras Syndrome in Dementia: A Systematic Review of Case Studies
Margariti C and Mircea MT
In an ageing population, dementia has become an imminent healthcare emergency. Capgras syndrome, the most common delusion of misidentification (DMS), is frequently found alongside dementia. Previous research showed that Capgras syndrome has significant negative effects on people living with dementia and their carers due to its complex presentation and impact on their lives. This qualitative systematic review explores the evidence base of the effective management and treatment of Capgras syndrome in dementia.

Multifunctional Tasks and an Energy Crisis are Crucial Players in Determining the Vulnerability of the Entorhinal Cortex to Early Damage in Alzheimer's Disease
Sivanesan S, Howell MD, Kaushik V, Jayakumar R, Pari SM and Goyal P
Alzheimer's disease (AD) is a devastating neurological disorder that affects synaptic transmission between neurons. Several theories and concepts have been postulated to explain its etiology and pathogenesis. The disease has no cure, and the drugs available to manage AD symptoms provide only modest benefits. It originates in the brain's entorhinal cortex (EC), with tau pathology that can proceed overt symptoms by decades and then spreads to other connected areas and networks to cause severe cognitive decline. Despite decades of research, the reason why the EC is the first region to be affected during AD pathophysiology remains unknown. The EC is well connected with surrounding areas to support the brain's structural and functional integrity, participating in navigation, working memory, memory consolidation, olfaction, and olfactory-auditory coordination. These actions require massive energy expenditure; thus, the EC is extremely vulnerable to severe hypometabolism and an energy crisis. Unfortunately, the crucial events/factors that make the EC vulnerable to pathological sequelae more than other brain regions have not been thoroughly explored. An in-depth analysis of available research on the role of the EC in AD could provide meaningful insights into the susceptibility of this region and its role in propagating AD. In this review article, we highlight how the functional complexities of the EC account for its vulnerability in AD.
Alzheimer's Disease and Vascular Dementia, Connecting and Differentiating Features
Hurła M, Banaszek N, Kozubski W and Dorszewska J
Alzheimer's disease (AD) and vascular dementia (VD) are the leading causes of dementia, presenting a significant challenge in differential diagnosis. While their clinical presentations can overlap, their underlying pathologies are distinct. AD is characterized by the accumulation of amyloid plaques and neurofibrillary tangles, leading to progressive neurodegeneration. VD, on the other hand, arises from cerebrovascular insults that disrupt blood flow to the brain, causing neuronal injury and cognitive decline. Despite distinct etiologies, AD and VD share common risk factors such as hypertension, diabetes, and hyperlipidemia. Recent research suggests a potential role for oral microbiota in both diseases, warranting further investigation. The diagnostic dilemma lies in the significant overlap of symptoms including memory loss, executive dysfunction, and personality changes. The absence of definitive biomarkers and limitations of current neuroimaging techniques necessitate a multi-modal approach integrating clinical history, cognitive assessment, and neuroimaging findings. Promising avenues for improved diagnosis include the exploration of novel biomarkers like inflammatory markers, MMPs, and circulating microRNAs. Additionally, advanced neuroimaging techniques hold promise in differentiating AD and VD by revealing characteristic cerebrovascular disease patterns and brain atrophy specific to each condition. By elucidating the complexities underlying AD and VD, we can refine diagnostic accuracy and optimize treatment strategies for this ever-growing patient population. Future research efforts should focus on identifying disease-specific biomarkers and developing more effective neuroimaging methods to achieve a definitive diagnosis and guide the development of targeted therapies.

Hamdi A, Baroudi S, Gharbi A, Babay W, Laaribi AB, Kacem I, Mrabet S, Zidi I, Klibi N, Gouider R and Ouzari HI
Alzheimer's disease (AD) is the most prevalent neurodegenerative disorder, with a significant burden on global health. AD is characterized by a progressive cognitive decline and memory loss. Emerging research suggests a potential link between periodontitis, specifically the presence of oral bacteria such as (), and AD progression. produces an enzyme, Agmatine deiminase (AgD), which converts agmatine to N-carbamoyl putrescine (NCP), serving as a precursor to essential polyamines. Recent studies have confirmed the correlation between disruptions in polyamine metabolism and cognitive impairment.
"Cyclophilin A" Enzymatic Effect on the Aggregation Behavior of 1N4R Tau Protein: An Overlooked Crucial Determinant that should be Re-considered in Alzheimer's Disease Pathogenesis
Ranjbar S, Mehrabi M, Akbari V, Pashaei S and Khodarahmi R
Neurodegenerative disorders like Alzheimer's disease (AD) involve the abnormal aggregation of tau protein, which forms toxic oligomers and amyloid deposits. The structure of tau protein is influenced by the conformational states of distinct proline residues, which are regulated by peptidyl-prolyl isomerases (PPIases). However, there has been no research on the impact of human cyclophilin A (CypA) as a PPIase on (non-phosphorylated) tau protein aggregation.
