This past year, therapeutic antibodies massively reduced brain amyloid, blood tests came into their own, and systems-based approaches transformed the study of gene expression, glial cells, and selective vulnerability.
An ultrasensitive assay picked up elevated concentrations of N-terminal tau fragments in the blood of people with AD.
Case study in early onset AD finds PET ligand tracks regional tau burden.
In patients across a range of neurodegenerative diseases, NfL ramps up in the cerebrospinal fluid. Levels are higher in those with worse disease.
FDG PET revealed the formation of a new functional brain network. It explains clinical improvements noted previously.
In sporadic and familial forms of AD, progranulin climbs in the cerebrospinal fluid as disease progresses, perhaps reflecting microglial activation.
Researchers are applying the proposed 2018 NIA-AA diagnostic criteria to three large, standing cohorts. How did the research framework perform?
People with a lot of neurofilament light protein in their spinal fluid are more likely to develop mild cognitive impairment in the next four years.
Large IDEAS data set establishes that PET scans are valuable in clinical practice. Other studies suggest CSF biomarker ratios perform nearly as well.
Scientists at CTAD were excited about postmortem validation of tau scans and new, more sensitive tracers. Others are exploring practical applications for live imaging of tau pathology.
With plasma tests performing in AIBL staging, scientists are sharing data across platforms and cohorts, and tackling standardization to avoid time lost to irreproducibility.
Neurofilament light protein in the serum registers the degree of axonal damage after cardiac arrest, and may help doctors predict long-term consequences for the brain.
At a workshop on engaging more black Americans in ADRD research, new CSF findings stood out against a general dearth of data on Alzheimer’s disease in underrepresented minorities.
Despite having a higher incidence of Alzheimer’s or a related dementia, relatively few black people participate in research studies or drug trials. How to achieve full representation?
Serial data establishes different trajectories for CSF t-tau and p-tau.
