High blood pressure refers to the state where the pressure or tension that makes our blood on the walls of the arteries is higher than normal. Headaches, dizziness and blurred vision often are some of the symptoms that identify hypertension, and knowledge is essential to prevent the severity of the problem.

The pressure has two values, the minimum, also known as diastolic pressure and the maximum or systolic pressure. A normal blood pressure value is less than 130 over 85. When we hypertension is diagnosed, it is important to recognize the factors that may be altering this state, so that in the same way, we can begin to combat it. Read the rest of this entry »

Cerebro Vascular Accident (CVA) or stroke is a vascular disease with degenerative consequences affecting the brain arteries that reach the brain.

Because even stroke, nerve cells (neurons and glia) of the brain are starved of oxygen and nutrients and lose their function, appearing box half-body paralysis, slurred speech, coma, etc.

The LCA is divided into two groups: ischemic (lack of blood) or bleeding.

In the first case there is an obstruction to the passage of blood to the brain.

In other cases, what occurs is the rupture of a cerebral artery (for aneurysms or hypertension). Intracerebral hemorrhage occurring abroad can not be released because the brain is enclosed in the skull bone.

Thus the blood as soft pressing, the brain, causing lack of oxygen to the area and the subsequent tissue injury (cerebral ischemia).
