Study: Silent strokes may cause memory loss in elderly

Silent strokes may not cause any noticeable symptoms but can result in small pockets of dead brain cells.

Scientists say evidence of silent strokes can be found in roughly a quarter of older adults and in some cases may be responsible for memory loss in the elderly.

A new study in the journal Neurology tested participants 65 and older with brain scans and gauged their memory, language skills, thinking speed and visual perception.

Authors of the study hope their information may lead to further insight into what causes symptoms of dementia and Alzheimer's and help develop new interventions for prevention.
