Scientists have made a huge breakthrough
Scientists studying the relationship between dementia and high blood pressure have made a huge breakthrough, as they have discovered how the former affects the brain.
Academics found that areas of the brain linked to memory loss and thinking skills are especially impacted by high blood pressure. Until now, it was not known exactly how high blood pressure damages the brain and new findings may impact how dementia is treated in the future, Wales Online reports. Scientists looked at those with genes associated with high blood pressure, making them more likely to develop the malady in life. If certain genes that cause the condition are linked to a part of the brain's structure - it may be high blood pressure that's causing the problems in that area "leading to problems with memory, thinking and dementia".
They also looked at genetic information from genome-wide association studies from three international groups and a technique called 'Mendelian randomisation'. This was done to see if high blood pressure was actually the root cause of changes to specific parts of the brain - as opposed to merely being associated with the changes.
