Groundbreaking blood test could detect Alzheimer's disease '17 years early'
Groundbreaking blood test could detect Alzheimer's disease '17 years early' This sensor could also predict the likelihood of developing Parkinson's disease An experimental blood test could detect a devastating disease almost two decades before a typical diagnosis. A new report has found that this test could predict Alzheimer’s disease 17 years earlier than usual. The findings, published in the Journal of Physical Chemistry B, also suggest that this test could detect Parkinson’s disease early.
Early Detection of Alzheimer's Disease Using Explainable Machine Learning on Clinical Biomarkers: A Multi-Class Classification Study Using the Alzheimer's Disease Neuroimaging Initiative (ADNI) Dataset
Announce Type: new Abstract: Background: Alzheimer's disease (AD) affects over 55 million people worldwide. Accurate, interpretable detection of normal cognition (NC), mild cognitive impairment (MCI), and AD from routine clinical assessments remains a critical unmet need. Methods: An XGBoost classifier was developed for three-class detection using eight clinical features from the Alzheimer's Disease Neuroimaging Initiative (ADNI): MMSE, CDR Global, CDR Sum of Boxes (CDR-SB), MoCA, FAQ, age,...
Everyday task may help detect early dementia signs before diagnosis, study finds
A simple writing test could detect cognitive impairment in older individuals before more serious symptoms occur, scientists have discovered. Writing is a complex, brain-heavy workout that requires the mind to process information, organize thoughts and send precise signals to the fingers all at once, according to experts. Because writing draws on so many complex mental functions, researchers believe that small changes in how people write could provide early warning signs for cognitive impairment.
A blood test could flag Alzheimer’s risk early. But how reliable is it?
Scientists have developed a blood test that could spot signals of Alzheimer's disease at a much younger age. A simple blood test may soon help identify people at higher risk of Alzheimer’s disease years before they develop symptoms, according to a new study. Researchers at the University of California, San Francisco (UCSF) in the United States, found that certain Alzheimer’s-related proteins in the blood were linked to small differences in thinking and memory among middle-aged adults who did...
Optical Conductivity as a Stage-Sensitive Imaging Biomarker for Alzheimer's Disease
Early detection of Alzheimer's disease (AD) remains limited by the inability of current imaging biomarkers to capture dynamic tissue changes preceding overt neurodegeneration. Conventional approaches primarily reflect molecular burden or structural atrophy and incompletely characterize the intermediate microenvironmental remodeling linking early pathology to clinical progression. Here, we introduce optical conductivity as a novel imaging biomarker characterizing tissue responses to...
What Do LLMs Know About Alzheimer's Disease? Multi-loss Fine-Tuning and Probing for AD Detection
arXiv:2602.11177v2 Announce Type: replace Abstract: Reliable early detection of Alzheimer's disease (AD) is challenging, particularly due to the limited availability of labeled data. While large language models (LLMs) have shown strong transfer capabilities across do mains, adapting them to the AD domain through supervised fine-tuning remains largely unexplored. In this work, we empirically evaluate various model architectures across three heterogeneous transcript corpora (Pitt, CCC, ADRC)...
Graph-Guided Universum Learning in Generalized Eigenvalue Proximal SVMs for Alzheimer's Disease Classification
arXiv:2606.04699v1 Announce Type: new Abstract: Early and accurate detection of Alzheimer's disease (AD) is important for timely intervention and disease management. Generalized Eigenvalue Proximal Support Vector Machine (GEPSVM) and its Universum-based variants have shown promising results for AD classification. However, existing methods treat Universum samples as independent points and do not consider the geometric relationships among them.
Unsurprising truth about Donald Trump's 'extreme intelligence' cognitive test which isn't an intelligence test
Unsurprising truth about Donald Trump's 'extreme intelligence' cognitive test which isn't an intelligence test Donald Trump has boasted about his "extreme intelligence" after taking a cognitive test during his latest routine physical examination - the only problem is that the test doesn't even assess intelligence, ironically Donald Trump claimed his latest cognitive test results showed he had "extreme intelligence", except the exam doesn't test for intelligence. The US President said he...
Scientists found the hidden switch fueling alzheimer’s brain inflammation
Scientists found the hidden switch fueling alzheimer’s brain inflammation Scientists may have found a hidden Alzheimer’s “inflammation switch”—and turning it off protected brain connections in early studies. - Date: - May 31, 2026 - Source: - Scripps Research Institute - Summary: - Scientists at Scripps Research have uncovered a molecular “switch” that appears to fuel the damaging brain inflammation seen in Alzheimer’s disease. They found that a protein called STING becomes chemically...
