New clinical study to test retinal screening processes for early detection of Alzheimer's disease

The University of Rhode Island, in collaboration with BayCare Health System in Florida and The Memory and Aging Program at Butler Hospital, an affiliate of The Warren Alpert Medical School of Brown University, is launching a clinical trial of retinal screening processes that could help clinicians detect Alzheimer's disease possibly two or more decades before patients develop life-altering clinical symptoms.

New radiotracer can provide insights into how the heart recovers after myocardial infarction

Insights into how the heart recovers after myocardial infarction (heart attack) can be obtained with a new radiotracer that targets fibroblast activity prior to it causing permanent damage.

Tau-protein better predicts brain atrophy in Alzheimer's patients than amyloid plaques

Brain imaging of pathological tau-protein "tangles" reliably predicts the location of future brain atrophy in Alzheimer's patients a year or more in advance, according to a new study by scientists at the UC San Francisco Memory and Aging Center. In contrast, the location of amyloid "plaques," which have been the focus of Alzheimer's research and drug development for decades, was found to be of little utility in predicting how damage would unfold as the disease progressed.

Education level and socioeconomic status can predict thinking and memory performance

How well eight-year-olds score on a test of thinking skills may be a predictor of how they will perform on tests of thinking and memory skills when they are 70 years old, according to a study published in the October 30, 2019, online issue of Neurology, the medical journal of the American Academy of Neurology.

Multi-centre registry trial tests use of PSMA tracer for early detection of prostate cancer

Led by researchers at Lawson Health Research Institute, a multi-centre registry trial is testing the use of a new imaging tracer, called a PSMA tracer, for early detection of recurrent prostate cancer. The registry gives patients access to a new type of imaging and will assess the impact on patient care.

Johns Hopkins researchers reveal why deep brain stimulation improves Parkinson’s symptoms

In a new study of seven people with Parkinson’s disease, Johns Hopkins Medicine researchers report evidence that deep brain stimulation using electrical impulses jumpstarts the nerve cells that produce the chemical messenger dopamine to reduce tremors and muscle rigidity that are the hallmark of Parkinson’s disease, and increases feelings of well-being.
