Alzheimer’s blood test performs as well as FDA-approved spinal fluid tests

A simple blood test to diagnose Alzheimer’s disease soon may replace more invasive and expensive screening methods such as spinal taps and brain scans. A study by researchers at Washington University School of Medicine in St. Louis and Lund University in Sweden shows that a blood test can be as good at detecting molecular signs […]

Study defines disparities in memory care

Patients who live in less affluent neighborhoods and those from underrepresented racial or ethnic groups are less likely than others to receive specialized care for dementia, including Alzheimer’s disease, a new study from Washington University School of Medicine in St. Louis indicates. Further, the research shows that Black people are more likely than white people […]

Tau-based biomarker tracks Alzheimer’s progression

Two pathologies drive the progression of Alzheimer’s disease. Early on, amyloid beta plaques lead the way, but around the time cognitive symptoms arise, tau tangles take over as the driving force and cognition steadily declines. Tracking the course of the disease in individual patients has been challenging because there’s been no easy way to measure […]

Alzheimer’s blood tests more likely to misdiagnose Black patients, study finds

Several blood tests used to diagnose Alzheimer’s disease are less accurate for African Americans than white patients, according to research from Washington University. The gold standard for Alzheimer’s diagnosis typically involves brain imaging and spinal fluid testing, but in recent years, biotech companies have developed an array of cheaper, less invasive blood tests to detect […]

Race of people given Alzheimer’s blood tests may affect interpretation of results

Three experimental blood tests used to identify people in early stages of Alzheimer’s disease perform differently in Black individuals compared to white individuals, according to a new study from Washington University School of Medicine in St. Louis. The study showed that a fourth blood test — the PrecivityAD test, which is commercially available in the […]

Risky driving behaviors increase as common sleep disorder worsens

People with sleep apnea wake up tired in the morning, no matter how many hours they actually sleep. The condition causes them to briefly stop and restart breathing dozens or even hundreds of times a night. Even though such breathing interruptions often don’t awaken those with apnea, they prevent them from sinking into deep, refreshing […]

Board grants faculty appointments, promotions, tenure

At the Washington University in St. Louis Board of Trustees meeting March 4, numerous faculty members were appointed or promoted with tenure or granted tenure, effective July 1 unless otherwise indicated. Promotion with tenure Carlos A. Botero to associate professor of biology in Arts & Sciences; Caitlyn M. Collins to associate professor of sociology in Arts & […]

Time until dementia symptoms appear can be estimated via brain scan

Researchers at Washington University School of Medicine in St. Louis have developed an approach to estimating when a person who is likely to develop Alzheimer’s disease, but has no cognitive symptoms, will start showing signs of Alzheimer’s dementia. The algorithm, available online in the journal Neurology, uses data from a kind of brain scan known […]

Wash U Researchers Find Blood Test Can Detect Early Alzheimer’s Symptoms

For years, doctors have used an expensive brain scan to detect symptoms of Alzheimer’s disease. But researchers at Washington University have found that a simple blood test could be similarly effective, according to a study published this month in the journal Neurology. A blood test to diagnose early symptoms could help make finding a cure […]

Blood test is highly accurate at identifying Alzheimer’s before symptoms arise

Up to two decades before people develop the characteristic memory loss and confusion of Alzheimer’s disease, damaging clumps of protein start to build up in their brains. Now, a blood test to detect such early brain changes has moved one step closer to clinical use. Researchers from Washington University School of Medicine in St. Louis […]

A Blood Test for Alzheimer’s? It’s Coming, Scientists Report

For decades, researchers have sought a blood test for beta amyloid, the protein that is a hallmark of Alzheimer’s disease. Several groups and companies have made progress, and on Thursday, scientists at Washington University in St. Louis reported that they had devised the most sensitive blood test yet. The test will not be available for […]
