What percentage of strokes are ischemic?

Explanation:
Most strokes are ischemic, meaning they’re caused by a blockage that cuts off blood flow to part of the brain. In typical data, ischemic strokes make up about 80–85% of all strokes, while hemorrhagic strokes account for roughly 15–20%. TIAs are brief episodes of symptoms due to temporary ischemia but aren’t completed strokes, and “global” isn’t a stroke type. So the statement that best reflects the common distribution is ischemic, representing the majority of strokes with about four-fifths to five-eighths of cases.
