Researchers have developed a new method that can predict biological age based on metabolites, substances produced by metabolic processes in our bodies. This so-called “metabolomic aging clock” provides an indication of how rapidly the body is ageing. Studies show that a higher predicted age using this clock is associated with an increased risk of dementia.
Metabolites are small molecules that are formed and broken down during metabolism. By measuring which substances are present and in what quantities, one can see how the body is functioning. Such a biological clock based on this data not only helps to better understand ageing, but can also signal health risks at an early stage.
Developing clocks of this kind is relatively straightforward nowadays and costs less money and time than it used to. Nevertheless, applying such clocks requires some caution, as it remains unclear how they will react to new treatments that might potentially slow down ageing. Therefore, the main focus is on improving the reliability of these measurement tools.
These insights are of importance to anyone interested in healthy ageing. Such tools may help in the future to make a better assessment of brain health – even before symptoms arise. In this way, timely intervention can be made with lifestyle changes or therapies that reduce the risk of dementia.
