Blood tau clock could forecast when Alzheimer’s symptoms begin

A Nature Medicine study describes a blood test that detects an abnormal form of tau in the blood, which may serve as a molecular clock to predict not only if someone will develop Alzheimer’s but also when symptoms could start. If validated in larger trials, it could enable earlier interventions and streamline clinical testing for therapies, though experts caution that it’s not yet recommended for cognitively unimpaired individuals to use this biomarker outside of research.

Blood biomarkers hint at decades-early warning for Parkinson’s

A European study found that blood biomarkers linked to early DNA repair and cellular stress, identified with machine learning, may reveal Parkinson’s long before motor symptoms, paving the way for inexpensive blood tests and earlier treatment—with clinical usage potentially within five years—though brain changes may not fully match blood signals and no cure exists.

Finger-prick blood test could speed Alzheimer's diagnosis in international trial

An international trial enrolling about 1,000 volunteers over 60 in the UK, US and Canada is testing whether a simple finger-prick blood test can detect Alzheimer's-related biomarkers to diagnose the disease more quickly and non-invasively, potentially replacing or reducing reliance on expensive brain scans and lumbar punctures; results are expected in 2028.

China rolls out blood-based Alzheimer's tests from BGI and Roche

BGI Genomics and Roche Diagnostics have rolled out blood-based tests for Alzheimer's in China, expanding access to screening and monitoring across Guangzhou, Qingdao, Shenzhen, Wuhan and Boao. BGI says its test is an auxiliary tool and not a standalone diagnosis, while Roche’s pTau181 test has begun clinical use in Boao and could streamline patient pathways and access to treatments such as Leqembi and Kisunla.

Understanding LDL Cholesterol and Ways to Reduce It

Understanding LDL Cholesterol and Ways to Reduce It

LDL cholesterol, often called 'bad' cholesterol, can build up silently in arteries, increasing the risk of heart disease and stroke. It is essential to have regular blood tests to monitor levels, ideally keeping LDL below 100 mg/dL, and to understand that genetics and aging also influence cholesterol levels. Managing diet, lifestyle, and regular check-ups are key to controlling LDL cholesterol and maintaining heart health.
