Simple blood test predicts Alzheimer risk years before symptoms appear

A simple blood test can predict Alzheimer's-related cognitive decline years before symptoms appear, ScienceDaily reported. In a large international study, researchers determined that individuals identified at the highest risk face a 38 percent chance of cognitive impairment within five years and an estimated 78 percent chance within 10 years.

Scientists believe the discovery could help identify people at risk before they experience noticeable problems with memory or thinking. The test is expected to pave the way for earlier intervention and future treatments designed to prevent Alzheimer's disease. [1]

Alzheimer's disease is a neurodegenerative disease and represents the most common cause of dementia, accounting for around 60 to 70 percent of cases. Early symptoms typically involve difficulty in remembering recent events, progressing to language problems, disorientation, and behavioural changes. [3]

As HEROIC BREAKING NEWS reported earlier, scientists at the University of Bonn previously reprogrammed blood cells from an 80-year-old person into neural stem cells with a molecular age under 20. Such advancements, alongside new predictive blood tests, provide critical tools for studying cellular rejuvenation and addressing age-related neurodegenerative diseases. [1][4]
