A stroke occurs when blood isn’t reaching part of the brain, depriving it of oxygen and causing brain cells to die. It’s an extremely serious event that can cause sudden weakness, numbness, paralysis, sensory disability (trouble seeing, speaking, etc.), brain damage, and even death.
Often caused by blood clotting, a transient ischemic attack (TIA) or “mini stroke” is similar to a stroke in that blood doesn’t reach the brain. The difference is that TIAs are brief, so the damage isn’t long-term. Still, a TIA is a serious condition that increases the risk of a stroke and demands emergency care.
