A study reported in the journal Neurology is known that memory loss in adults may be caused by silent stroke due to small spots which caused the death of cells in the brain.
Silent stroke is a type of ischemic stroke is characterized by blood clots in the arteries that supply blood to the brain causing brain damage which in the long run lead to memory loss.
"Usually people think of memory loss as an early indicator of Alzheimer's disease, but it could be a sign of silent stroke," said Adam Brickman, neuropsychology from Columbia University's Taub Institute for Research on Alzheimer's Disease and the Aging, as quoted by ABCNews, Friday, 30/12/2011 ).
Brickman said the people who experience memory loss due to silent stroke is not always indicate a decrease in the size of the hippocampus. But if the consequences of Alzheimer's is caused by changes in the size of the hippocampus and the blood vessels in the brain.
The study involved 658 participants with an average age of 79 years with no history of dementia (dementia). Participants are given tests to measure memory, language skills and the ability to think and measure the hippocampus.
Currently known risk factors for silent stroke include high blood pressure conditions, obesity and high cholesterol. This is almost the same as other types of stroke.
"Now many people who suffer a stroke at a young age. During the time that stroke will cause much damage, unfortunately this problem due to stroke is irreversible," said Dr. Shazam Hussain, director of the stroke program at Clevelend Clinic.
One way you can do to prevent stroke is to control symptoms or risk factors exist. Method of screening with MRI can also monitor the condition of the brain in people at high risk.
