A vascular stroke occurs when blood flow to the brain is blocked or interrupted. Because the cells in the brain are being deprived of oxygen and nutrients, they begin to die. The sooner an individual experiencing a stroke gets medical attention the better his chances of recovery and survival. Knowing the signs and symptoms of a vascular stroke will aid you in getting proper medical care--either for yourself or your loved ones.
Numbness
Individuals suffering from a stroke will often experience either weakness or numbness in the muscles of the face, leg, or arms. These symptoms usually occur on one side of the body, often the left side, but can affect either side and in some cases both sides. These symptoms usually come on suddenly as opposed to gradually over time.
Vision
Another common symptom of a vascular stroke is a change in vision. An individual suffering from a stroke may suddenly have trouble seeing out of one eye. Because vision problems in one eye often affect the other eye, the individual having the stroke may report having trouble seeing out of both eyes at the same time.
Dizziness
Because strokes affect oxygenated blood flow to the brain, the individual experiencing a stroke may suddenly become dizzy. He may, at the same time, find that he has trouble walking, is losing his balance, or suddenly lacks coordination. It is important to take note of these symptoms and make sure that the person suffering is seated quickly to avoid further injury from a related fall.
Headaches
Because vascular strokes have such a strong and sudden impact on the brain, the individual suffering may begin to complain of a sudden headache. These headaches often appear to have no cause and are usually caused by the lack of blood flow to the brain (an ischemic stroke) or by excess blood flow to the brain (hemorrhagic stroke).
Speech Impairment
Some of the most common signs of a stroke involve confusion, speech impairment and an inability to comprehend what others are saying. These symptoms will have a sudden onset. Bystanders may notice that a person who just moments before was having a normal conversation, now is suddenly slurring his speech or appears to be confused.
Window of Opportunity
The longer an individual experiences decreased blood flow to the brain the greater the chances of permanent damage. Bystanders who notice someone suffering stroke symptoms should call 911 immediately. Most patients experience the best recovery if they seek treatment within 60 minutes of the onset of a stroke.
