Smartphone Tests Detect Frontotemporal Dementia
Cognitive tests administered through a smartphone mobile application (app) accurately and reliably detected frontotemporal lobar degeneration (FTLD), also known as frontotemporal dementia (FTD), an observational study showed. The smartphone tests had moderate to excellent internal consistency and test-retest reliability (intraclass correlation coefficient range of 0.77-0.95), according to Adam Staffaroni, PhD, of the University of California […]
Alzheimer’s Supplements Fail Compared With Generic Drugs
Galantamine sold as prescription generic drugs was labeled accurately and free of contamination, but galantamine sold as dietary supplements was not, an analysis showed. Across 10 brands of dietary supplements, the actual quantity of galantamine — a plant alkaloid with anticholinergic effects used to treat Alzheimer’s dementia — was anywhere from 2% to 110% of […]
Parkinson’s Biomarker Shows High Accuracy
An alpha-synuclein seed amplification assay (SAA) accurately detected Parkinson’s disease in cerebrospinal fluid (CSF) and identified people with early, non-motor symptoms prior to diagnosis, cross-sectional data from the Parkinson’s Progression Markers Initiative (PPMI) showed. Sensitivity for Parkinson’s disease overall was 87.7% and specificity for healthy controls was 96.3%, reported Andrew Siderowf, MD, of the University […]
Google Commits To I.D. Real Abortion Clinics So Women Won’t Be Tricked By Fakes

Artificial intelligence to help predict Arctic sea ice loss
A new AI (artificial intelligence) tool is set to enable scientists to more accurately forecast Arctic sea ice conditions months into the future. The improved predictions could underpin new early-warning systems that protect Arctic wildlife and coastal communities from the impacts of sea ice loss. Published this week (Thursday 26 August) in the journal Nature […]
