Researchers at the University of Turku have discovered new changes in blood samples associated with Alzheimer’s disease. A new study was conducted on disease-discordant Finnish twin pairs: one sibling suffering from Alzheimer's disease and the other being cognitively healthy. The researchers used the latest genome-wide methods to examine the twins' blood samples for any disease-related differences in epigenetic marks which are sensitive to changes in environmental factors. These differences between the siblings were discovered in multiple different genomic regions. Development of the late-onset form of Al...

DiscussionOur results suggest a sexual dimorphism in BACE1-related upstream mechanisms of brain Aβ production and deposition. We argue that plasma BACE1 should be considered in further biomarker validation and qualification studies as well as in BACE1 clinical trials.

A technology that originated at the University of Minnesota is well on its way to commercialization thanks to an investment award from Alzheimer's Drug Discovery Foundation (ADDF). The investment of up to $500,000 was awarded through the ADDF's Diagnostics Accelerator initiative. Toronto, Ontario-based RetiSpec licensed through the University of Minnesota's Technology Commercialization program. The technology (shown on the right) harnesses hyperspectral imaging and machine learning.  RetiSpec Eye Scanner 3.jpeg "We are focused on bringing to market a noninvasiv...

Conclusion[18F]RO948 and [18F]flortaucipir bound comparably in neocortical regions, but [18F]RO948 showed higher retention in the medial temporal lobe and lower intracerebral “off-target” binding. Time-dependent bias of SUVR estimates may prove less of a factor with [18F]RO948, compared with previous tau ligands.

ConclusionWe suggest a one-step quantification method for amyloid PET via a deep learning model. The model is highly reliable to quantify the amyloid PET regardless of multicenter images and various radiotracers.

It seems that the tipping point has been reached in the Alzheimer's research and development community, in the sense that it is becoming more widely accepted that new approaches are needed. The failure to produce significant benefits to patients via clearance of amyloid from the brain by immunotherapy has spurred a great deal of theorizing, and several new and promising lines of work. For example, working on restoring age-related declines in drainage of cerebrospinal fluid might remove all metabolic waste from the brain. Alternatively, a focus on neuroinflammation and the role of dysfunctional microglia is suggested, parti...

The objective of this study was to assess the usefulness of the appropriate use criteria (AUC) for amyloid imaging in an unselected cohort. METHODS: We calculated sensitivity and specificity of appropriate use (increased confidence and management change), as defined by Amyloid Imaging Taskforce in the AUC, and other clinical utility outcomes. Furthermore, we compared differences in post-positron emission tomography diagnosis and management change between "AUC-consistent" and "AUC-inconsistent" patients. RESULTS: Almost half (250/507) of patients were AUC-consistent. In both AUC-consistent and AU...
