A silent stroke occurs when small blood vessels in the brain become blocked or rupture. They are called silent strokes because they are not accompanied by the classic warning signs of stroke such as severe headaches, dizziness or loss of motor skills.
Individuals often don t realize they ve even had a stroke.
Over time, these smaller blood vessels are unable to deliver blood or oxygen to the brain, and cells die. Eventually, an individual may develop problems with memory or concentration and may even have difficulty walking. N.C. Researchers say the findings suggest that individuals, especially those at risk for stroke, need to be carefully monitored for depression. Depression may indicate that a silent stroke has already occurred. Further work is needed to see if individuals with silent strokes are at risk to develop larger strokes and vascular dementia - a condition of memory loss and other cognitive problems that result from stroke.
