Abstract Alzheimer’s disease (AD) is the most common neurodegenerative worldwide. Amyloid-β (Aβ) accumulation and neurofibrillary tangles are two key histological features resulting in progressive irreversible neuronal loss cognitive decline. The macrophages of central nervous system (CNS) belong to innate immune comprise parenchymal microglia CNS-associated (CAMs) at CNS interfaces (leptomeninges, perivascular space choroid plexus). Microglia CAMs have received attention as they may play a role onset progression e. g., by clearing amyloid beta through phagocytosis. Genome-wide association studies (GWAS) revealed that human express numerous risk genes for AD, further highlighting their potentially critical AD pathogenesis. tightly controlled environmental factors, such host microbiota. Notably, it was reported composition gut microbiota differed between patients healthy individuals.

Abstract Alzheimer’s disease (AD) is neuropathologically characterized by the extracellular deposition of amyloid-β peptide (Aβ) and intraneuronal accumulation abnormal phosphorylated tau (τ)-protein (p-τ). Most frequently, these hallmark lesions are accompanied other co-pathologies in brain that may contribute to cognitive impairment, such as vascular lesions, transactive-response DNA-binding protein 43 (TDP-43), and/or α-synuclein (αSyn) aggregates. To estimate extent AD patients, several biomarkers have been developed. Specific tracers target visualize Aβ plaques, p-τ αSyn pathology or inflammation positron emission tomography. In addition imaging biomarkers, cerebrospinal fluid, blood-based biomarker assays reflecting AD-specific non-specific processes either already clinical use development. this review, we will introduce pathological brain, related discuss what respective determined at post-mortem histopathological analysis. It became evident initial stages plaque not detected with currently available biomarkers. Interestingly, precedes deposition, especially beginning when unable detect it.

Although current excellent pathologies, they fail which analysis required. Accordingly, neuropathological studies remain essential understand development early stages.

The identification of neuroinflammation as a critical factor in Alzheimer's disease (AD) has expanded the focus research beyond amyloid-β and tau pathology. neuroinflammatory fluid biomarkers GFAP, sTREM2, YKL-40 have gained attention for their potential early detection monitoring progression. Plasma GFAP demonstrated promise predicting conversion from mild cognitive impairment to AD dementia, while sTREM2 highlights microglial activation, although there are conflicting results regarding its dynamics pathogenesis. Advanced imaging techniques, such PET tracers targeting TSPO MAO-B, also been developed visualize glial activation vivo, offering spatial temporal insights into processes. However, clinical implementation these faces challenges due lack specificity, many them can be elevated other conditions. Therapeutic strategies emerging, with TREM2-targeting therapies antidiabetic drugs like GLP-1 receptor agonists showing modulating activity.

Alzheimer’s disease (AD) is a major neurodegenerative dementia, with its complex pathophysiology challenging current treatments. Recent advancements have shifted the focus from traditionally dominant amyloid hypothesis toward multifactorial understanding of disease. Emerging evidence suggests that while amyloid-beta (Aβ) accumulation central to AD, it may not be primary driver but rather part broader pathogenic process. Novel hypotheses been proposed, including role tau protein abnormalities, mitochondrial dysfunction, and chronic neuroinflammation. Additionally, gut–brain axis epigenetic modifications gained attention as potential contributors AD progression. The limitations existing therapies underscore need for innovative strategies. This study explores integration machine learning (ML) in drug discovery accelerate identification novel targets candidates. ML offers ability navigate AD’s complexity, enabling rapid analysis extensive datasets optimizing clinical trial design. synergy between these themes presents promising future more effective

Some patients undergoing surgical procedures display long-term post-surgery cognitive impairment (post-operative dysfunction; POCD), which may precipitate progression to dementia. We investigated whether preoperative defined using specific tests (Paired-Associates Learning and Spatial-Span from the Cambridge Neuropsychological Test Automated Battery, (CANTAB) was associated with increased risk of POCD. N = 590 >65years a matched control group n=114 comprised final sample. Patients were classified as impaired if composite memory-score derived two CANTAB test battery (spatial working memory paired-associate learning) scored 1 SD below norms normative database. Risk developing POCD 3 months higher [odds ratio 2.048 (95% CI 1.027 - 4.087)] for those pre-surgical compared no impairment. This suggests that on hippocampus-based tasks spatial-span paired-associates learning is in older patients.
