A recent study has shown that organs age at different rates, with an ageing immune system being tied to dementia and Alzheimer’s.
The study, which was published in the Lancet Health journal, has examined certain proteins found in people’s organs to show that our body parts can age at different rates.podcast that examining the physical age of a person’s individual organs can also predict the likelihood of that person developing certain diseases.“So, the bottom line from this first part was they noticed in some people the organs are ageing more quickly,” he said.
“Very importantly then, they had the health records of these people in their seventies - the key bottom line people with heart disease in their 70s, when they were 55, their heart was older than the average. Prof O’Neill said this was significant as these individuals had shown no other clinical evidence of having heart disease in their 50s.“The one that really stood out was dementia, they were expecting to see markers of brain ageing,” he said.
“One big headline is a more rapidly ageing immune system is a risk factor for developing dementia and Alzheimer’s in this situation.”Health advice“Blood tests – because remember, it’s all in the blood, which is tremendous – may advise whether a person needs to take better care of a particular organ and potentially provide an early warning signal that they may be at risk of a particular disease,” he said.
