Healthy cells are constantly breaking down proteins and building up new ones with the help of enzymes aptly named unfoldases, ...

are the commonest causes of presenile dementia. In the absence of a biological marker, diagnosis is reliant on clinical evaluation. Confirmation is often sought from neuroimaging, including ...

PET scans and careful follow-up to see if the plaques are present, indicating Alzheimer’s disease. “Above all, a lab number is only meaningful when interpreted alongside medical history ...

This test marks a significant advancement as it identifies amyloid plaques in the brain—a hallmark of Alzheimer’s disease—using a simple blood sample. Previously, detecting these plaques required ...

These plaques can be detected and visualized using amyloid positron emission tomography (PET) brain scans, often years before clinical symptom onset, to aid in diagnosing Alzheimer’s disease.

For the millions of Americans affected by Alzheimer's. The road to battling the disease ... cognitive and functional evaluations, brain imaging, spinal fluid analysis and, more recently, blood ...

This test measures pTau217 and β-amyloid 1-42 proteins to detect amyloid plaques, a key Alzheimer's sign. Initially used to rule out the disease, positive results will prompt further advanced ...

that is a key marker for Alzheimer’s. Previously, the only FDA-approved methods for detecting amyloid were invasive tests of spinal fluid or expensive PET scans. The blood test identifies a ...

The Food and Drug Administration has greenlit Japan-based test manufacturer Fujirebio to begin marketing its blood test for helping doctors diagnose Alzheimer's disease in some patients ...

Other options to detect Alzheimer's include procedures such as a spinal tap, which requires an invasive puncture to collect spinal fluid, or an expensive PET brain scan that may not be reimbursed ...

Humans are uniquely vulnerable to Alzheimer’s, unlike other primates. New research points to tau tangles, not beta-amyloid, as the key driver, challenging current treatment approaches and offering ...
