At AAIC, researchers touted phospho-tau species, especially p217 and p181. They tick up in CSF as an early response to amyloid accumulation.
In 2,144 Colombian ADAD family members, plasma NfL in gene carriers rises as early as two decades before their symptoms start.
At AAIC, researchers presented baseline data from an ongoing, five-year study asking whether the anti-Aβ antibody crenezumab can forestall cognitive decline in autosomal-dominant Alzheimer’s disease.
Longitudinal data identifies four stages of amyloid plaque buildup, with the earliest deposits appearing in the precuneus and posterior cingulate.
The field is searching for a combination of clinical features and biomarkers that will identify the disease in people with mild cognitive impairment.
In carriers of a PD-causing mutation, PET scans showed serotonin transporter loss before motor symptoms set in.
Fully automated immunoassay could offer cost-effective screening for AD.
A meta-analysis of 47 studies suggests CSF NfL is particularly elevated in a select few, suggesting it could help in differential diagnosis.
In healthy, older adults specific EEG patterns correlated with plaque and tangle burdens.
Using different techniques, contestants vied for the best way to tell which ADNI participants would develop clinical, cognitive, or imaging signs of Alzheimer’s disease.
Serial amyloid and tau scans in cognitively healthy people indicate that the speed at which a person’s tau accumulates best predicts his or her future cognitive decline.
In a research study, one-fifth of healthy people who learned they were at high risk for AD said they might consider physician-assisted death as a future option.
In ADNI, blood marker exposes ongoing neurodegeneration across disease stages.
Scientists know that the retina changes in people with preclinical AD; alas, there is neither consensus nor convergence in the field of retinal imaging. An upcoming initiative aims to determine which measures are most robust.
Scientists are probing saliva and skin secretions for telltale signs of Parkinson’s disease. Their prize? A diagnostic test at the pre-motor stage.
