Memory Loss in Older Adults Are tied Up with Silent Strokes

Many individuals nowadays are having increased health risks of developing certain diseases because of unhealthy lifestyle which include smoking, heavy alcohol drinking, stressful work conditions, and unhealthy food options. Because of these, many individuals are suffering from hypertension, diabetes, and even stroke, and all of these diseases when it becomes complicated due to failure of lifestyle modification can actually lead to even more serious illness and hence, can even lead to death. One of the most usual end results of unhealthy lifestyle habits is stroke. The general public must be wary and vigilant about those individuals who are having the health risks because silent strokes can already be happening without anyone noticing it, and more so, other complications as a result of silent stroke can occur.

In fact, according to new study, some memory loss in older adults can actually occur as a result of silent stroke. This is probably because of the some tiny damaged parts of the brains which were brought about by the stroke process.

The new study which was published in the journal Neurology involved the analysis and examination of data gathered from about 658 individuals who belong to the age group of 79 on average. These study participants do not have any history of dementia or any memory loss. During the gathering of data, the researchers allowed the study participants to undergo series of tests which measure the participant’s memory, communication skills, and cognitive abilities. In addition, the study participants had to undergo MRI scans in order to measure the size of the hippocampus – a part of the brain which has functions on memory and emotions.

Upon the analysis of data, results of the MRI scans revealed that about 174 of the study participants had actually experienced silent strokes. Also, the same participants had poor performance during the tests conducted which measure the memory of the participants. That is despite the size of their hippocampus.

Moreover, according to Adam Brickman, assistant professor of neuropsychology at Columbia University’s Taub Institute for Research on Alzheimer’s disease and the Aging, and co-author of the study, he said: In the findings of the study “we showed that above and beyond size, stroke also contributed to the memory loss and could be a potential indicator for Alzheimer’s development.”
