Can blocked blood vessels cause a stroke?

Blocked blood vessels can increase a person's risk for stroke.  Ischaemic strokes occur when an artery that carries blood to a part of the brain is blocked, so that brain part is unable receive oxygen and glucose.

 As an analogy, it's like having a blocked pipe in your sprinkler system, and a part of your garden doesn't get watered...causing the plants to die.

hope this helps,
