![]() Alcoholics and drug addicts are also at high risk of suffering from a stroke. ![]() In general, people who are at the highest risk are those who have high blood pressure, poor cardio and arterial health, high blood cholesterol or calcium levels and who are overweight. Those involved in vehicle accidents or similar physical injuries may suffer a stroke in this way. Strokes can also happen as a result of high pressure where blood vessels rupture in the brain. When hard plaques break off, they have the potential to cut or bruise the walls of your arteries and veins, which may cause more damage in the event of a stroke. This forces the heart to pump faster in an attempt to shift the blockage - however, in the event that it is not capable, a stroke will occur. Plaques can also buildup to the point that they create a blockage. When hard or soft plaques break off, they travel loosely in the bloodstream and may block a smaller capillary in or close to the brain. This can especially be seen in patients who have osteoporosis or a condition where calcium does not remain inside the bones and forms lumps in the blood stream. In some cases, plaques undergo aggregation, where they oxidize and become hard lumps. They usually form by attaching to the walls of veins and arteries. Plaques are essentially soft deposits that are made up of cholesterol, calcium, cellular waste products, toxins and protein. Strokes usually happen due to the formation of plaques in the blood stream in combination with high blood pressure.
