Stroke was recognized as a major cause of disability in our modern society. It occurs, if one of the arteries, which normally supply brain tissue with blood, becomes occluded or bursts. In 80% of cases stroke develops as a result of vessel's blockage (ischemic type), caused by fatty accumulations on the arteries' lining.
Occasionally brain artery may tear. As a result, blood flows out into the tissue and damages brain cells. It was found that people with diabetes, unmanaged hypertension, heart arrhythmia and obesity have much higher chances of stroke occurrence. In addition to this, certain habits like smoking and alcohol misuse may extremely increase your risks of this life-threatening disorder.
In 2005 the journal Neurology published results of the study, which shows that there are certain warning signs, appeared several days or weeks before ischemic stroke eventually occurs. Transient ischemic attack becomes apparent in stroke-like symptoms, which go away after several minutes.
According to the research of the American Academy of Neurology, 549 of 2416 people with ischemic stroke experienced TIA prior to the accidence. 43% of them had mini-stroke within seven days before the trouble and 17% - one day the day of the full-fledged stroke. Symptoms of stroke may vary, depending on localization, size of affected artery and type of the disease.
It's worth knowing these warning signs, your body sends you several weeks or month before stroke development:
#1. Weakness and numbness of the extremities
These symptoms usually occur in the arm and leg on the one side of the body, or may affect only lower/upper extremities.
#2. Trouble with speaking
Slurred speech, forgetting familiar words and inability to repeat the simple sentences may be a sign of blocked brain vessels.
#3. Loss of coordination
Unsteadiness, walking problems and lost balance usually show that something goes wrong in the cerebellum (area of the brain, located behind the two cerebral hemispheres).
#4. Vision problems
Blurred vision, double vision or other troubles, which occur abruptly, may be a warning sign of forthcoming stroke.
many of those, who experienced stroke, have noticed dizziness and unusual vertigo some time before the trouble.
#6. Behavioral changes
