Roche's Elecsys pTau181 test has a 97.9% negative predictive value to rule out amyloid pathology, which will improve referral decisions and expedite treatment.

As dementia care grows more complex and more promising, the role for front-line clinicians is becoming more nuanced and more essential.

The ReCODE program targets metabolic, infectious, immune, vascular, and toxic exposures, elements that underlie both mood and cognition, study authors said.

If primary care clinicians are to meet the cognitive screening demands that are growing with an aging population, they need the sharpest tools in the box, this expert says.

A cognitive health assessment will soon be as routine as taking blood pressure or pulse oximetry, says neurocognitive researcher David J. Libon, PhD. He talks more about that future.

Acoustic variables, like shimmer and jitter, that are typically undetectable in human speech can be detected with tablet technology and serve as biomarkers for mental acuity.

The program's interventions enhanced cognitive function in older adults at risk for dementia, highlighting the importance of healthy behaviors.

The ability to observe an early marker of Alzheimer disease progression noninvasively marks a new phase of research with potential for improved disease management.
