'Bio-barcoding' promises early Alzheimer's diagnosisTopics: Health Issues
Combining magnetic and gold nanoparticles with strands of DNA could allow the early detection of Alzheimer's disease. If successful, future treatments could then be used to prevent symptoms from ever appearing.
Identifying and tracking Alzheimer's disease currently relies on brain imaging and psychological testing. A firm diagnosis can only be made by autopsy.
However, recent studies have revealed several biochemical markers that may provide the basis for a living diagnosis. These include tiny proteins called amyloid-beta-derived diffusible ligands (ADDLs), which exist at elevated levels in the brains of Alzheimer's patients.
