A stroke occurs when the blood supply to a certain part of the brain is reduced or interrupted. Without oxygen and nutrients from the blood, brain cells cannot function properly and eventually die.
There are 2 major types of strokes: ISCHEMIC stroke caused by a BLOCKED artery, and HEMORRHAGIC stroke caused by a RUPTURED artery.
Ischemic stroke happens when a blood clot OBSTRUCTS an artery. In some patients, the clot forms locally, inside the blood vessels that supply the brain. This occurs when fatty deposits in an artery, or cholesterol plaques, rupture and trigger blood clotting. In other cases, a clot may travel to the brain from elsewhere in the body. Most commonly, this happens in patients with atrial fibrillation, a heart condition in which the heart does not pump properly, blood stagnates in its chambers and this facilitates blood clotting. The clots may then pass into the bloodstream, get stuck in smaller arteries of the brain and block them.
Hemorrhagic stroke, on the other hand, occurs when an artery leaks or ruptures. This can result from high blood pressure, overuse of blood-thinners/anticoagulant drugs, or abnormal formations of blood vessels such as aneurysms and AVMs.
As a hemorrhage takes place, brain tissues located BEYOND the site of bleeding are deprived of blood supply. Bleeding also induces contraction of blood vessels, narrowing them and thus further limiting blood flow.
Stroke symptoms may include one or more of the following:
– Paralysis of muscles of the face, arms or legs: inability to smile, raise an arm, or difficulty walking.
– Slurred speech or inability to understand simple speech.
– Sudden and severe headache, vomiting, dizziness or reduced consciousness.
Cerebral stroke is a medical emergency and requires immediate attention. It is essential to determine if a stroke is ischemic or hemorrhagic before attempting treatment. This is because certain drugs used for treatment of ischemic strokes, such as blood thinners, may CRITICALLY aggravate bleeding in hemorrhagic strokes.
– For ischemic strokes, emergency treatment aims to restore blood flow by removing blood clots. Medication, such as aspirin and tissue plasminogen activator, TPA, are usually the first options. TPA may be given intravenously, or, in the case the symptoms have advanced, delivered directly to the brain via a catheter inserted through an artery at the groin. Blood clots may also be removed mechanically by a special device delivered through a catheter.
– Emergency treatment for hemorrhagic strokes, on the other hand, aims to stop bleeding, reduce blood pressure, and prevent vasospasm and seizures. These goals are usually achieved by a variety of drugs. If the bleeding is significant, surgery may be required to drain the blood and reduce intracranial pressure.
Preventive treatments for strokes include:
– Removal of cholesterol plaques in carotid arteries that supply the brain
– Widening of narrowed carotid arteries with a balloon, and sometimes, a stent. This is usually done with a catheter inserted at the groin.
– Various procedures to prevent rupturing of brain aneurysms, such as clipping and embolization.
– Removal or embolization of vascular malformations
– Bypassing the problematic artery

    Magnesium chloride cleans blood vessels and therefore prevents and avoids stroke. Because it removes the fats from the blood vessels and impurities inside them that clog them up. It improves the varicose veins as well or makes them disappear, and lowers the pressure of those who have high blood pressure, making it lower and normalize and never getting high again. But it has to take for a while and then stop. It cannot take forever, because otherwise it may give some problem. Hope it helps everyone and hugs!

    I had an AVM in 1980 in cerebellum. I have poor balance, coordination, and dysarthria. I’ve never had seizures and take no perscriptions. I eat healthy and exercise. I’m almost 74 and good health for all things considered. Only thing was last lipid was 220 overall cholesterol level, LDL 139, and HDL 72. Do i need to be concerned since HDL is very good…..and a congenital problem and not a heart problem? Please help as it is so hard to find a doctor that doesn’t push pills, but rather takes a more natural approach. Thank you!
