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.
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.
Large IDEAS data set establishes that PET scans are valuable in clinical practice. Other studies suggest CSF biomarker ratios perform nearly as well.
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.
In sporadic and familial forms of AD, progranulin climbs in the cerebrospinal fluid as disease progresses, perhaps reflecting microglial activation.
FDG PET revealed the formation of a new functional brain network. It explains clinical improvements noted previously.
What's the use of measuring neurofilament light in blood? The marker could help with AD trial enrollment and measuring drug effects. It could even guide brain-sparing improvements in heart surgery, say researchers at AAIC 18.
Tau’s apparent lockstep with cognitive decline dominated the PET conversation. Piramal flaunted data, and Merck/Cerveau are close behind. A first stab at imaging synapses in the hippocampus drew notice, too.
In patients across a range of neurodegenerative diseases, NfL ramps up in the cerebrospinal fluid. Levels are higher in those with worse disease.
Researchers are applying the proposed 2018 NIA-AA diagnostic criteria to three large, standing cohorts. How did the research framework perform?
An ultrasensitive assay picked up elevated concentrations of N-terminal tau fragments in the blood of people with AD.
Stakeholders have until February 11 to comment on draft FDA guidance for biomarker qualification.
In familial Alzheimer’s disease, rise in NfL in the blood precedes disease onset by 16 years.
A longitudinal study finds that middle-aged people with the highest levels of inflammation markers in their blood succumb to the greatest cognitive decline over the next 20 years.
A comparison of these large data sets shows that while the two forms of Alzheimer’s disease have separate triggers, they follow the same course and are much more similar than different.
