2023年10月13日 · Development of in vivo biomarkers has shifted the diagnosis of Alzheimer’s disease (AD) from the later dementia stages of disease towards the earlier stages and has introduced the potential for pre-symptomatic diagnosis.

Conventionally used biomarkers for Alzheimer’s disease (AD) include positron emission tomography (PET) and single-photon emission computed tomography (SPECT) to examine brain function and nuclear magnetic resonance to analyze structural changes in the brain.

It has been shown that the amyloid beta biomarker shows 80% or above sensitivity and specificity, in distinguishing AD from dementia. It is believed that amyloid beta as a biomarker will provide a future for diagnosis of AD and eventually treatment of AD. [3]

Research suggests that Alzheimer's disease in early stages may cause changes in the levels of biomarkers, like tau and beta-amyloid, found in cerebrospinal fluid.

2023年9月4日 · We review recent results that enable pathological staging of AD with neuroimaging and fluid-based biomarkers, with a particular emphasis on the role of amyloid, tau and neuroinflammation in...

2024年12月1日 · To standardize and guide the clinical application of blood-based biomarkers for AD, we have compiled a summary of recent advancements in clinical research and developed ten recommendations using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) methodology.

Accumulating data from the clinical research support that the core Alzheimer's disease (AD) cerebrospinal fluid (CSF) biomarkers amyloid-β (Aβ42), total tau (T-tau), and phosphorylated tau (P-tau) reflect key elements of AD pathophysiology.

Currently, Aβ 1–42, phosphorylated tau, and total tau levels in the cerebrospinal fluid are the best-studied fluid biomarkers for AD, but the need for novel, cheap, less-invasive, easily detectable, and more-accessible markers has recently led to the search for new blood-based molecules.

Current diagnostic tools in the brain, such as magnetic resonance imaging (MRI), positron emission tomography (PET) imaging, and cerebrospinal fluid (CSF) biomarkers (Aβ and tau) detection are invasive and expensive.

2024年2月21日 · Preclinical Alzheimer’s disease has been characterized by the presence of normal cognitive function and abnormal levels of cerebrospinal fluid (CSF) biomarkers. 1 The preclinical stage is...

Current review provides a comprehensive survey of biomarkers for AD, elucidating their diverse roles across different aspects of the disease.

2024年2月21日 · The pathologic features of the brain in patients with Alzheimer’s disease include extracellular amyloid plaques, intraneuronal neurofibrillary tangles, and the loss of neurons and synapses.

2025年2月25日 · While numerous studies have explored the diagnostic performance of blood-based biomarkers for detecting Alzheimer's disease (AD), 1-10 relatively few have conducted a comprehensive head-to-head comparison of multiple biomarkers in patients presenting at memory clinics, 11-16 where patients often exhibit a broad spectrum of symptoms. Blood-based ...

Blood-based biomarkers hold great promise to revolutionize the diagnostic and prognostic work-up of Alzheimer’s disease (AD) in clinical practice. This is very timely, considering the recent development of anti-amyloid-β (Aβ) immunotherapies.

A 2024 study suggests that fasting blood samples are more reliable than non-fasting ones, 5 given the effect of food intake on the concentrations of blood-based biomarkers for Alzheimer’s disease. 6 A growing number of candidate blood-based biomarkers have also emerged in addition to p-tau181, including p-tau231, p-tau217, neurofilament light ...

2025年2月19日 · The quest to identify reliable biomarkers for early detection of Alzheimer’s disease (AD) and monitoring disease progression has gained significant momentum in recent years [].Established AD biomarkers included positron emission tomography (PET) [2,3,4] and cerebrospinal fluid (CSF) measurements [2, 5, 6], which reflect the neuropathological …

Single biomarkers offered good discrimination between patients with disease and control cases, but achieving a distinction between dementia cases required a combination of biomarkers. The biomarker profiles were rather similar across different FTD phenotypes, except for higher levels of neurodegenerative biomarkers in PGRN carriers.
