New research suggests that in some recent cases the memory loss among elderly is experienced nay be due to so-called “silent strokes,” according to the team study, such strokes, which may not cause any noticeable symptoms are majorly seen as a result in small pockets of dead brain cells, and are found in roughly 25 percent of older adults.

According to the study author, Adam Brickman, of the Taub Institute for Research on Alzheimer’s Disease and the Aging Brain at Columbia University Medical Center in New York, explained in a news release from the American Academy of Neurology said that the new aspect of this study of memory loss in the elderly is to examines silent strokes and brain shrinkage simultaneously.

During the study, the authors concluded that after working with 658 men and women aged 65 and older, none of whom had a history of dementia. These participants were taken for MRI brain scans, as well as testing to gauge their capacities in terms of memory, language skills, thinking speed and visual perception during the study.

During which it was revealed that 174 of the participants had experienced silent strokes during the brain scan and while testing their memory the investigators found that these seniors did not perform as well on the memory exams. Further these findings were helpless to guess whether the part of the patient’s brain responsible for memory (the hippocampus) was found to be relatively small or not.

In the news release, Brickman noted that while given, conditions like Alzheimer’s disease are defined mainly by memory problems, their results may lead to further insight into what causes symptoms and the development of new interventions for prevention. He also further added that memory loss is separately associated in their study while finding reports for silent strokes and the volume of the hippocampus and their association, hence, their result may also support stroke prevention as a means for staving off memory problems.
