Automated method identifies and tracks harmful tau deposits involved in Alzheimer's disease

Amyloid-beta and tau are the two key abnormal protein deposits that accumulate in the brain during the development of Alzheimer's disease, and detecting their buildup at an early stage may allow clinicians to intervene before the condition has a chance to take hold.

Study shows link between early brainstem tau accumulation and cortical hyperexcitability

Study conducted by researchers from the GIGA CRC In vivo Imaging laboratory at ULiège demonstrates, for the first time in humans, how the first deposits of tau proteins in the brainstem are associated with neurophysiological processes specific to the early stages of Alzheimer's disease development.

Whole body imaging detects more myeloma-defining disease, allows treatment to be initiated earlier

Researchers from King's College London have shown that whole body magnetic resonance imaging (WBMRI) not only detects more myeloma-defining disease than positron emission tomography/computed tomography (PET/CT) with 18F-fluorodeoxyglucose (FDG) but that it also allows critical treatment to be initiated earlier.
