Blood Test Identifies Clinically Relevant Alzheimer’s Disease Pathology In Several Clinical Syndromes, Study Finds

MedPage Today (2/10, George) reports, “A blood test identified clinically relevant Alzheimer’s disease pathology in several clinical syndromes, a clinicopathological study showed.” Researchers found that “plasma phosphorylated tau 217 detected Alzheimer’s pathology across neurodegenerative syndromes with an area under the receiver operating characteristic curve of 0.95.” Study results indicate that “the blood-based biomarker performed slightly better in Alzheimer’s-related syndromes...than in frontotemporal lobar degeneration-related syndromes.” The findings were published in JAMA Neurology.
