Memory Loss in Adults: New Finding
Loss of memory is a common phenomenon and seen mostly with aging adults. It is really debilitating for hapless individuals and hampers with their daily lives. Till now scientists believed memory loss to be a result of damage to hippocampus which is a part of the brain responsible for memory and related functions. Though there is no denying the role of hippocampus and its deterioration leading to memory loss, latest research conducted by Adam Brickman suggests there may be other causes of memory loss too.
This research says that though memory loss takes place because of shrinkage or degeneration of hippocampus, tiny strokes that are also called silent strokes have an active association with lapses in memory. So far scientists have linked strokes with loss of cognitive abilities that can be described as ability to make linkages in the mind, processing of information etc, but never has there been any attention to loss of memory because of strokes.
The research conducted study on 658 senior people with ages more than 65. They were healthy people with no record of dementia. Later, these people were checked again and 174 people of this group were found to have suffered from tiny, silent strokes that did not necessitate any hospitalization. These were the people who performed badly in memory tests among the lot.
