An Ischemic Stroke is the result of an inadequate supply of blood and oxygen to the brain. Approximately 80 percent of strokes are ischemic. There are two types of ischemic strokes:
Thrombotic (cerebral thrombosis)
In a thrombotic stroke, a blood clot or thrombus forms in one of the brain's arteries and blocks the flow of blood to the brain. The cells in the affected area stop functioning and die quickly.
Embolic (cerebral embolism)
An embolic stroke occurs when a blood clot travels through the heart and lodges in a brain artery, impairing the flow of blood to the brain.
Transient Ischemic Attack (TIA) occurs from a thrombus or embolus that temporarily interrupts blood flow to a portion of the brain. TIA Symptoms
occur in one third of stroke victims prior to the actual stroke. TIA should be considered as seriously as stroke.
