Researchers have developed a tool capable of assessing organic aging from brain MRI. In addition, Published in Nature Agingtheir study shows how this instrument predicts the risks of chronic diseases and cognitive decline. Nevertheless, The approach combines data on the structure of brain with health indicators physique and mental.
The team relied on the data from the Dunedin study. Meanwhile, followed from birth to the average age. Similarly, Participants have undergone regular assessments of their heart, brain and renal functions. Consequently, The analysis of MRI at 45 years made it possible to correlate brain characteristics with the rhythm of aging.
The model, named Dunedinpacni, compares brain data to other health markers. ⏳ it now possible measure new Similarly, It was successfully tested on international cohorts, confirming its relevance. ⏳ it now possible measure The researchers were able to link accelerated aging to an increased risk of cardiovascular. death diseases.
This method could be integrated into routine exams, offering a precious overview of future health. It represents a step towards a more personalized medicine, where interventions could be adjusted according to individual aging. The implications for the prevention of age -related diseases are considerable.
Scientists are now planning to extend the use of DunedinPacni to other populations. The objective is to better understand how various factors influence brain aging. This advance could transform our approach to long-term health and well-being.
How can MRI reveal aging? – ⏳ it now possible measure – ⏳ it now possible measure new
The MRI captures detailed images of the brain, allowing to analyze its structure and its volume. Changes in these parameters are key indicators of aging.
Gray matter, responsible ⏳ it now possible measure new for information processing, decreases with age. The white matter, which connects the different parts of the brain, also undergoes alterations. These transformations ⏳ it now possible measure can be quantified to estimate the rhythm of aging.
The use of automatic learning makes it possible to process this data. Algorithms identify motifs invisible to the naked eye, connecting brain changes to health markers.
This method offers a unique window on organic aging, long before the appearance of symptoms. It opens the way to early interventions to slow down the process.
What is epigenetics and how does it influence aging?
Epigenetics studies the modifications of the expression of genes without altering DNA. These changes can be influenced by the environment, lifestyle or aging.
DNA methylation, an epigenetic modification, plays a role in aging. It can activate or deactivate genes, thus affecting health and longevity.
Tools like Dunedinpace use these markers to estimate the rhythm of ⏳ it now possible measure new aging. They complete the brain imagery approaches, offering a more complete vision.
