People with Down syndrome nearly always develop signs of Alzheimer’s as they age. School of Medicine researchers are taking part in a multisite study to understand how Alzheimer’s develops in this population, with a long-term goal of finding ways to prevent or treat the disease.
A new grant for research at the School of Medicine focuses on brain scans and other markers of Alzheimer’s. The aim is to establish whether early markers of disease in white populations also apply to African Americans.
Older people without cognitive problems who experience a fall may have undetected neurodegeneration in their brains that puts them at high risk of developing Alzheimer’s dementia, according to a study from Washington University School of Medicine.
Researchers at Washington University School of Medicine have shown that levels of a specific protein in the blood rise as amyloid plaques form in the brain. The discovery could pave the way toward a blood-based test to diagnose Alzheimer’s disease before symptoms appear.
Lack of sleep could help promote the development of Alzheimer’s disease, according to two studies from Washington University School of Medicine in St. Louis. The studies could help identify people at high risk of developing Alzheimer’s dementia and point to strategies for prevention.
The School of Medicine led an international trial evaluating whether investigational drugs could slow memory loss and cognitive decline in a rare, inherited form of Alzheimer’s disease. The trial was conducted at 24 sites in Australia, Canada, France, Spain, the United Kingdom and the United States.
Researchers at the School of Medicine have discovered that the genetic variant APOE4 – long linked to dementia – spurs the spread of harmful clumps of Parkinson’s proteins through the brain. The findings suggest that therapies that target APOE might reduce the risk of dementia for people with Parkinson’s disease.
School of Medicine researchers have received $29 million from the National Institute on Aging of the National Institutes of Health to continue a long-running, international Alzheimer’s study aimed at understanding how the disease develops and progresses.
A new School of Medicine study indicates that people with dementia — whose parents also had dementia — develop symptoms an average of six years earlier than their parents.
A School of Medicine study has found that brain immune cells called microglia form the crucial link between protein clumping and brain damage. Suppressing such cells might prevent or delay the onset of dementia in people.
