Difference between "brain hemorrhage" and "brain attack/stroke" ?

A few: A brain attack or stroke maybe from lack of blood flow(ischemic) or a bleed(either clot/embolism or aneurysm) in the brain(intraparenchemal). Both results in death of brain tissue. Other sources of hemorrhage can be in the surrounding tissues such as subdural(around the brain) or subarachnoid(around brain or spinal cord).

The term "Brain Attack" was coined to convey the need for urgent intervention when circulation to the brain is obstructed and refers to the timely administration of TPA to attempt clearing of the thrombus or embolus. A true hemorrhage would not be a candidate for TPA, but likely should be included in the "attack" category due to its high lethality.
