develop diseases such as heart disease And diabetes Chances of this happening before the age of 55 may increase significantly dementia In later life, a new study suggests.
stroke or onset mental health situations like Worry And Depression According to research, the risk can increase twofold between 55 and 70.
expert of University of Oxford said up to 80 percent dementia Patients suffer from two or more chronic health conditions, but have a “deficiency” Understanding“When it comes to specific diseases, age of onset and link dementia,
They identified “critical time windows” in which certain diseases pose the greatest risk to patients.
For study, published in brain communicationResearchers analyzed data from 282,712 people using the UK Biobank and looked at patterns of 46 chronic health conditions.
He found that heart conditions are heart disease And irregular heartbeatas well as diabetesThose before the age of 55 were most strongly associated with dementia risk.
However, by age 55 to 70, mental health situations like Worry And DepressionAdditionally, conditions such as stroke doubled the risk of dementia.
Sana Suri, Associate Professor and Senior Fellow at Oxford Brain Sciences, said: “Although we knew that multimorbidity increased the risk of dementia, it was not clear which combinations of health conditions had the greatest impact and in what order.
“This study has revealed how specific diseases coexist with each other, and the critical time windows in which they may pose the greatest risk.”
Elsewhere, studies find people with conditions who heart disease And diabetes In middle age, conditions such as stroke arise later mental health The disorders had the greatest risk of developing dementia.
Common early symptoms of dementia

Different types of dementia can affect people differently, and everyone will experience symptoms in their own way.
However, some common early symptoms may include:
- memory loss
- difficulty concentrating
- Difficulty performing familiar daily tasks, such as being confused about the correct change when shopping
- struggling to follow a conversation or find the right words
- confusion about time and place
- mood changes
Dr. Suri said the presence of other diseases should also be taken into account when assessing a person’s risk of developing dementia, and this may help develop strategies that aim to reduce the risk at certain points in life.
He said: “This study has identified a relationship between multimorbidity and dementia risk but we need to understand more about why this happens.
“We also need to try to replicate the study in more diverse groups of people to make sure the results are representative of the population.
“Future studies could investigate whether efforts to manage or prevent cardiovascular problems in early to mid-life, followed by mental health and neurological disorders when people are in their 50s and 60s, could reduce the risk of dementia.”
