Adults who were born with heart disease are at a higher risk dementia according to a study. The study of more than 10000 adults with congenital heart disease (CHD) in Denmark discovered a particularly increased risk for early dementia in middle-age adults. We've learned that CHD is a lifelong condition says Nicolas Madsen senior author of the study. Research shows that children born with heart problems are at a greater risk for one or more neurodevelopmental issues when compared to children without heart disease. We can now say that the risk for these types of problems continues well into adulthood.
