The brain is one of the body’s many organs that is constantly active. It is composed of blood arteries, glial cells, meninges, cerebrospinal fluid, and nerve fibers. Blood vessel blockages can occur as a result of high blood pressure, smoking, diabetes, excessive cholesterol, obesity, and other conditions. This blockage in the brain causes a lack of oxygen and blood flow to the brain, resulting in a stroke.
However, there are instances when you have a temporary glitch, such as a brief weakness or confusion that quickly disappears. This is akin to a mini-stroke known as a Transient Ischemic Attack (TIA). This article focuses on distinguishing stroke from mini stroke.
Blood Flow Disruption
Stroke: This condition happens when there is a prolonged disruption in blood flow to the brain. This can happen due to bleeding (haemorrhagic stroke) from a rupture in the blood vessels or as a result of a blood clot (ischemic stroke) blocking the artery where blood passes.
Mini stroke or TIA (Transient Ischemic Attack): This is a brief halt in blood flow to the brain that lasts from a few minutes to hours. This temporary obstruction can be caused by small blood clots or spasms.
Symptoms
Both TIA and Stroke share the same symptoms similarities which includes:
- Weakness
- Speech problem
- Vision issues
- Dizziness
Note: TIA occurs briefly that the symptoms too are brief or mild and can go unnoticed and can resolve on its own.
Difference Between TIA and Stroke
Takeaway
Transient Ischemic Attack (TIA) and Stroke are equally dangerous medical conditions that stop blood flow to the brain. However, one is deadlier than the other. Strokes can cause lasting brain damage as a result of the prolonged disruption of blood flow. While TIA does not cause permanent brain damage, blood supply to the brain is restored after a few minutes or hours.
However, each of these health concerns necessitate rapid medical intervention. Immediate medical intervention after a stroke will help to reduce brain damage. While urgent medical intervention for a TIA will allow for an early assessment of underlying causes.
