18. Some strokes are directly linked to high blood pressure.
Strokes occur when part or all of the brain’s blood supply is cut off. While some strokes cause memory loss and behavioral issues, other strokes are deadly. The recovery period following a stroke can be anywhere from weeks to years, and the person may never recover a sense of normalcy. If blood pressure reaches dangerously high levels, a stroke can be imminent. A severe headache, nosebleed, shortness of breath, and ringing in the ears are signs that someone may be about to suffer a stroke, especially if blood pressure is above 180.
High blood pressure can cause another life-threatening condition in the brain, an aneurysm. Aneurysms form when the wall of a blood vessel weakens; it may balloon out, and a pool of blood inside can exert additional stress on the blood vessel. If the aneurysm bursts, the result is often uncontrolled bleeding. The person may die before anyone even knows that there is a problem.
