New Tool Predicts Dementia Risk Based on Aging Speed
Scientists have created a new tool called DunedinPACNI to check how quickly your body and brain are aging.
It uses brain scans to predict your risk of diseases like dementia.
If you're aging faster, you're more likely to get sick.
This tool is special because it studies the same people over time, making it more accurate.
As people live longer, there's a greater chance of age-related illnesses.
Researchers hope this tool will help people understand and manage their health better as they get older.
Scientists developed the DunedinPACNI tool to estimate individual chances of developing dementia and age-related diseases.
The tool uses MRI brain scans to predict the risk of chronic diseases.
Individuals with higher DunedinPACE scores showed a decline in overall health and were more likely to suffer age-related conditions.
The tool analyzed brain scans from 624 adults aged 52 to 89 participating in a North American Alzheimer's study.
The research strengthens the connection between biological aging and cognitive decline.
