A stroke can be a life-changing medical emergency and ranks among the leading causes of death and disability worldwide. It occurs when the blood supply to the brain is either disrupted or reduced, depriving the brain cells of essential oxygen and nutrients. Different types of strokes are caused by different factors. Here’s an overview of the potential causes of stroke.
Accounting for the majority of strokes, these are triggered by blockages (usually blood clots) in the blood vessels supplying the brain. The blockage can be the result of atherosclerotic plaques formed by the accumulation of fatty deposits within the vessel, or a traveling clot that has formed elsewhere in the body (such as the heart).
These occur when a blood vessel in the brain bursts, leading to bleeding in the surrounding brain tissue. The leading causes include high blood pressure, overuse of anticoagulants, and weakened blood vessel walls due to conditions like aneurysms.
Often called a “mini-stroke”, TIAs are caused by a temporary blockage in a blood vessel to the brain. Although its effects are temporary and typically resolved within 24 hours, a TIA is often a tocsin of a full-blown stroke and should not be ignored.
Risk factors that increase the likelihood of stroke include advanced age, a family history of stroke, smoking, uncontrolled high blood pressure, obesity, high cholesterol levels diabetes, and cardiovascular diseases.
Remember, recognizing the signs of a stroke early and seeking immediate medical attention can significantly improve outcomes and reduce the risk of lasting disability. Prioritizing a healthy lifestyle, managing existing health conditions, and regular check-ups are key to preventing stroke and promoting overall brain health. Express your care for yourself and your loved ones by recognizing and combating the preventable causes of stroke.
