Jul 28, 2024 · The new study used a blood test that focuses on a form of a protein called tau that sprouts into tangles in the brains of people with Alzheimer’s.
Testing for Alzheimer’s or other dementias entails diagnostic, cognitive or blood tests, MRI, CT or PET brain imaging, neurological exams or other assessments. Call our 24 hours, seven days a week helpline at 800.272.3900
Mar 13, 2024 · These tests are promising and may be used to pinpoint who is at risk of Alzheimer's dementia, and whether Alzheimer's is the cause of dementia. Scientists are investigating several disease markers and diagnostic tests.

Results were published on July 28, 2024, in JAMA. Across all the participants, the blood test predicted a diagnosis of Alzheimer’s with 88% to 92% accuracy. Further analysis found that measuring the proportion of p-tau217 alone yielded results similar to using both measures. The blood test performed far better than clinical evaluations done ...
In contrast, MRI, tau PET, and Aß PET provide global and regional information that may help direct assessment of disease stage and subtype in some clinical cases and clinical trials (See Molecular Imaging Biomarkers for Dementia in this issue).
Jul 28, 2024 · WASHINGTON (AP) — New blood tests could help doctors diagnose Alzheimer’s disease faster and more accurately, researchers reported Sunday – but some appear to work far better than others. It’s tricky to tell if memory problems are caused by Alzheimer’s.
Sep 24, 2023 · Evidence suggests that signs of Alzheimer's disease could be detected in the blood up to 20 years before symptoms start. Catching the disease this early could have a major effect on treatment outcomes for patients.
Jan 23, 2024 · Testing a person’s blood for a type of protein called phosphorylated tau, or p-tau, could be used to screen for Alzheimer’s disease with “high accuracy,” even before symptoms begin to show, a...
Aug 13, 2024 · Across all the participants, the blood test predicted a diagnosis of Alzheimer’s disease with 88% to 92% accuracy. Further analysis found that measuring the proportion of p-tau217 alone yielded results similar to using both measures. The blood test performed far better than clinical evaluations done without biomarker-based testing.
Jul 10, 2024 · Lab tests. Blood tests may help rule out other potential causes of memory loss and confusion, such as a thyroid disorder or vitamin levels that are too low. Blood tests also can measure levels of beta-amyloid protein and tau protein, but these tests aren't widely available and coverage may be limited.
