Individuals over 60, especially those with high blood pressure, are at an increased risk of experiencing a silent stroke , a new study has found.
Recent studies have concluded that individuals over 60 are at an increased risk of experiencing a "silent stroke", specifically those with high blood pressure.
"Silent" strokes are strokes that don't result in any noticeable symptoms but cause brain damage.
Diet and High Blood Pressure
High blood pressure or hypertension is defined as a blood pressure of above 140 mm Hg (systolic) and or 90mm Hg (diastolic).

"These strokes are not truly silent, because they have been linked to memory and thinking problems and are a possible cause of a type of dementia," said study author Perminder Sachdev, MD, PhD, of the University of New South Wales in Sydney, Australia.
"High blood pressure is very treatable, so this may be a strong target for preventing vascular disease," the expert added.
The study involved 477 people age 60 to 64 who were followed for four years. At the beginning of the study 7.8 percent of the participants had the silent lacunar infarctions, small areas of damage to the brain seen on MRI that never caused obvious symptoms. They occur when blood flow is blocked in one of the arteries leading to areas deep within the brain, such as the putamen or the thalamus.
At the end of the study, an additional 1.6 percent of the participants had developed "silent" strokes.

Also, people with another type of small brain damage called white matter hyperintensities were nearly five times as likely to have silent strokes as those without the condition.
