A Simple Scan Can Determine Aging Speed

Single MRI scan could be used to estimate dementia risk

New Zealand scientists have helped develop an internationally groundbreaking tool that estimates a person's risk of getting dementia and other age-related diseases.

A midlife MRI that spots rapid aging and signals disease long before symptoms

A new brain scan tool shows how quickly your body and mind are aging. It can spot early signs of diseases like dementia, long before symptoms begin. The scan looks at hidden clues in your brain to predict future health.

New brain scan tool predicts aging speed and dementia risk

Any high school reunion is a sharp reminder that some people age more gracefully than others. Some enter their older years still physically spry and mentally sharp. Others start feeling frail or forgetful much earlier in life than expected.

PRC2-AgeIndex as a universal biomarker of aging and rejuvenation

DNA methylation (DNAm) is one of the most reliable biomarkers of aging across mammalian tissues. While the age-dependent global loss of DNAm has been well characterized, DNAm gain is less characterized. Studies have demonstrated that CpGs which gain methylation with age are enriched in Polycomb Repressive Complex 2 (PRC2) targets. However, whole-genome examination of all PRC2 targets as well as determination of the pan-tissue or tissue-specific …

A simple scan can determine aging speed

For Tuesday, July 1, WGN’s Dina Bair has the latest on new medical information, including: More Coverage: WGN's Medical Watch Brain scan provides aging info Scientists say they can detect how rapidly the brain is changing, a knowledge that can predict dementia and other age-related diseases years before symptoms appear.  Duke University doctors used a single MRI to measure the aging rate.  They say the early alert can help people make choic…

A single brain scan can reveal how fast you're aging

Scientists have developed a method to determine an individual's aging speed using a single brain scan, providing insights into early signs of frailty or forgetfulness.
