Medical Definition of ischemic stroke

: stroke caused by the narrowing or blockage of a blood vessel supplying the brain

Note: Ischemic stroke is the most common type of stroke. Obstruction of a blood vessel supplying the brain results either from a clot that has traveled in the blood from another part of the body (embolism) or from a clot that has formed in place (thrombus).
