Brain Cell Biomarker for Preclinical Alzheimer Disease Identified

Brain Cell Biomarker for Preclinical Alzheimer Disease Identified

by Fernando Rigon | Jun 7, 2023 | News

Astrocytes, cells that are involved in the brain’s support system, might play an important role in the progression of Alzheimer disease, according to results from 1016 participants with and without amyloid-β pathology who were all cognitively unimpaired....
In Amyloid Cascade, Do Reactive Astrocytes Bridge Plaques and Tangles?

In Amyloid Cascade, Do Reactive Astrocytes Bridge Plaques and Tangles?

by Fernando Rigon | Jun 2, 2023 | News

Why do some people with amyloid plaques decline, while others do not? In the May 29 Nature Medicine, researchers led by Tharick Pascoal at the University of Pittsburgh laid some of the blame on reactive astrocytes. Among cognitively healthy people with amyloid...

Microglial and Astrocyte Reactivity Are Key to Determining Alzheimer’s Disease Progression

by Fernando Rigon | May 30, 2023 | News

Tharick Pascoal, MD, PhD (Associate Professor of Psychiatry) is an internationally recognized expert on the imaging and fluid biomarkers of Alzheimer’s disease and related dementias. He recently published two papers examining the multifaceted but interactive...
Alzheimer’s blood test edges closer as key brain cell identified

Alzheimer’s blood test edges closer as key brain cell identified

by Fernando Rigon | May 29, 2023 | News

A blood test that can detect people at early risk of Alzheimer’s is a step closer after scientists implicated a key brain cell in the development of the disease. As well as providing the basis for a test, their work points to a resolution of one of the persistent...
Prick of the bunch: Blood test can predict who’ll develop Alzheimer’s disease, ‘game-changing’ study suggests

Prick of the bunch: Blood test can predict who’ll develop Alzheimer’s disease, ‘game-changing’ study suggests

by Fernando Rigon | May 29, 2023 | News

Scientists may have found the true cause of Alzheimer’s disease — and believe the condition can be detected using a simple blood test. Experts have long known the build-up of amyloid in the brain is linked to the disease, but whether the plaques are a...
