Digital cognitive test offers early Alzheimer's screening in primary care

Alzheimer's disease is the most common cause of dementia. As new disease-modifying treatments for Alzheimer's disease are now becoming available, both early and accurate diagnosis in a resource-efficient assessment process ...

Neuroscience

Unique brain cell may hold key to Alzheimer's disorientation

Losing your sense of direction is one of the earliest and most distressing signs of advanced Alzheimer's disease. Now, a new study from the University of Michigan sheds light on a unique neuron that may hold the key to understanding ...

Cell defect in exosomes linked to development of Alzheimer's

They're tiny particles—with potentially huge human consequences. Researchers from Aarhus University have identified a defect in the production of so-called exosomes in cells, associated with a mutation seen in dementia ...

How a gift card could help speed up Alzheimer's clinical research

Offering a modest gift card significantly increased enrollment of low-income individuals in a patient registry designed to accelerate Alzheimer's disease clinical trials, a new USC study published in JAMA Health Forum finds.

Neuroscience

Early lead exposure could result in memory issues later in life

A new study has found that people who lived in areas with high levels of leaded gasoline emissions in the 1960s and '70s are more likely to report memory problems today—a finding that researchers say could deepen our understanding ...
