Blood test for clinical diagnosis of Alzheimer's unprecedented in new guidelines

The Alzheimer's Association released its first comprehensive clinical practice guidelines for the diagnosis, treatment, and care of Alzheimer's disease (AD) at the end of July. This landmark document places particular emphasis on blood-based biomarker testing as a core diagnostic tool for patients presenting

Women with Down syndrome may develop Alzheimer’s disease more rapidly than men

University of California - Irvine
Peer-Reviewed Publication

Brain tissue studies reveal more beta amyloid and tau accumulation in women with Down syndrome than in men.

Findings emphasize the importance of considering sex in the design of Alzheimer’s research and treatment.

The National Institutes of Health supported the study.

Neural navigation: FAU engineers, sensing institute map brain’s blood flow

Florida Atlantic University
Peer-Reviewed Publication

Not all blood vessels play equal roles in brain health. To uncover how the brain regulates its complex circulation, researchers built a detailed computer model of mouse brain vasculature. Focusing on transitional zone vessels—crucial links between arteries and capillaries—the model simulates how each segment adjusts like a tiny valve. It reveals how the brain stabilizes blood flow during pressure shifts or heightened activity, offering new insights into brain protection and potential breakthroughs in diagnosing stroke, Alzheimer’s, and traumatic brain injuries.

BU creates new AI tool to predict markers of Alzheimer’s disease

Boston University School of Medicine
Peer-Reviewed Publication

Researchers at Boston University Chobanian & Avedisian School of Medicine have built an artificial intelligence (AI) tool that can accurately predict key signs of Alzheimer's disease—such as the presence of sticky proteins called amyloid beta and tau—using common and less expensive tests like brain scans, memory checks and health records.

Nuclear speckle rejuvenation “next frontier” for treating neurodegeneration

University of Pittsburgh
Peer-Reviewed Publication

Targeting cellular structures called nuclear speckles could be a completely new approach for treating Alzheimer’s, Parkinson’s and prion diseases, according to new research led by the University of Pittsburgh.
