II. Symptoms of Stroke
Here are some symptoms of strokes:

1. Sudden trouble in standing
Sudden trouble in standing is an early symptom of stroke as a result of circulation of blood that carries oxygen to suddenly deplete caused by narrowing of arteries and high blood pressure.

2. Dizziness and loss of balance
The brain coordinates information from the eyes, the inner ear, and the body’s sense to maintain balance. If the cells of that part of the brain get damaged in result of depleted oxygen will cause dizziness and loss of balance.

3. Sudden confusion
A sudden onset of confusion means that something is potentially going wrong with the brain. Almost all conditions that affect the brain are life-threatening. It might be caused by a tumor or low levels of oxygen in the cells of the cerebral cortex in your brain that affect your ability to think with your usual speed or clarity. It might also be caused by lowered blood sugar, as is the case of diabetes.

4. Having trouble speaking and understanding
Having trouble speaking and understanding occurs when the brain cells in the area of the broca, wernicke and angular ayrus in the left hemisphere area begin to die because they stop getting the oxygen and nutrients they need to function.

6. Sudden severe headaches
Headache is a condition of pain in the head, sometimes neck or upper back pain may also be interpreted as a headache. It ranks amongst the most common local pain complaints and may be frequent for many people but sudden severe headaches may be caused by an early symptom of heart disease as we mentioned in previous articles, by rupturing a brain vessel or depletion of oxygen in some parts of the brain.

7. Sudden trouble seeing
This may be an early indication of stroke when the oxygen in the blood supply to the part of the brain is suddenly interrupted or when a blood vessel in the brain bursts, spilling blood into cells that control the vision area of the cerebral cortex in the brain.

III. The Risk Factors
1. Age
Human aging is the biological process that is unavoidable but controllable. Starting at age 40, the cells in our body begin this process causing the deterioration of some functions of our body. Most people of this age group already have some form of cholesterol building up in their arteries and high blood pressure resulting in an increased risk of stroke.

2. Heredity
People with a family history of stroke have a greater chance of stroke than those do not have such a family history.

3. Race
Because of frequent high blood pressure in African Americans, they have a significantly higher risk of stroke than their Caucasian counterparts.
