Hemorrhagic strokes - what are they and how do you know if you're having one. That's the focus of tonight's Ask the Doctor segment.

Dr. Timothy Louie is a neurologist with Saint Mary's Center for Neurovascular and Stroke Care. 

If you have a question for him, call 858-2222 between 5 p.m. and 6 p.m. tonight. 

There are two types of stroke, hemorrhagic and ischemic. Hemorrhagic strokes are less common, in fact only 15 percent of all strokes are hemorrhagic, but they are responsible for about 40% of all stroke deaths.

A hemorrhagic stroke is either a brain aneurism burst or a weakened blood vessel leak. Blood spills into or around the brain and creates swelling and pressure, damaging cells and tissue in the brain. There are two types of hemorrhagic stroke called intracerebal and subarachnoid.
