|Stroke ~ Risk Factors|
|There are many factors which increase the risk of Stroke
|Other factors can affect the risk of stroke?
|Older men and women are always at a risk of Heart Attack, Cancer and Stroke. Heart attack and stroke are inter-related in many aspects.Hypertension is the cause in both these lethal conditions.
Being careful about Lifestyle adds to protection against Stroke & Heart Attach.
|Doctors advise men over 40 to take a low-dosage, coated Aspirin – 81 mg. is standard daily to help prevent cholesterol build-up and blood clots.|
|Types of StrokeStroke can present in various forms. Diseases of Carotid arteries, that run along each side of neck, are mainly involved in the genesis of Stroke. These arteries supply blood from heart to the brain.Stroke is clinically of three types:
TIA – Transient Ischemic Attack or Mini Stroke:
In this type of stroke Fatty plaque is formed in the carotid arteries, and when it is sufficient enough to reduce critical amount of blood flow to the brain this type of transient ischemic attack occurs.
TIAs are extremely important stroke warning signs. Don’t ignore them!
Symptoms of TIA are
The effects of TIA are usually brief, but cannot be ignored because they indicate the possibility of a full-blown stroke in the future, or a heart attack. About a third of those suffering from TIA will have a stroke, often within a year.
In some patients the symptoms develop in the matter of hours or days. This may be due to cerebral tumour or subdural hematoma or may be due to slow occlusion of major cerebral vessels.
This is an episode of focal cerebral dysfuction due to cerebral infaction or haemorrhage, with symptoms lasting for longer than 24 hrs. Stroke usually evolve rapidly over a few minutes, and reach maximum disability within an hour or two. Sometimes a slower course occurs.
Cerebral Thrombosis: is caused by blood clot in one of the arteries in the brain. The clot may have travelled in the neck or the brain from other part of the body.
Hemorrhagic Stroke: involves a blood vessel in the brain which may have burst or leaked blood.
Both these types cause destruction of the crucial brain cells by depriving them of oxygen and sugar, which may take few minutes to hours.
Body builder – had Stroke after taking energy suppliments
The 33-year old young man, who used to train two hours daily as a body builder, purchased energy supplements over the counter. The MaHuang supplement contained 20 mg of ephedra, 200 mg caffeine, and other compounds. Each day, the man took four to six of these pills, as well as a daily creatine supplement containing 6000 mg of the drug. The man, who worked as a baggage handler in an airport, had the stroke about six weeks after starting to take the supplements. He awoke one morning unable to speak, and with weakness in his right arm and the right side of his face. Brain scans showed that he had had a stroke, where the blood supply to part of his brain had been cut off, perhaps by a clot. The patient had no vascular risk factors, in particular no tobacco use, and he was perfectly fit until his stroke.
The supplements he was taking, however, have been associated with adverse side effects. Ephedrine has been linked to stroke, heart attack and psychosis. Large doses of caffeine also affect the heart. Although cardiovascular problems have not been reported with creatine, the drug may have negative effects when combined with supplements, particularly those that affect the sympathetic nervous system. Creatine has also led to kidney problems.
