What is TIA?

TIA stands for ‘Transient Ischemic Attack’. TIA feels like a stroke and all the symptoms show that it’s a stroke but it is a temporary stroke. It is also known as a mini-stroke.

TIA is caused because of the interruption of blood flow and oxygen to the brain just like a stroke though it lasts for only a while, the blood flow returns after a temporary interruption.

The blockage happens for a while and the blood flow returns to normal on its own.

Usually, a TIA attack lasts for a few minutes to a few hours, mostly for less than an hour. The symptoms include trouble walking, blurred vision, slurred speech, numbness of the body, etc.

The TIA doesn’t leave permanent damage and can be cured up to a point. Though it can be a sign of a future stroke. So it is necessary for immediate medical attention.

TIA can occur because of health-related problems like high blood pressure, high cholesterol, diabetes, atrial fibrillation, smoking, drinking, etc. The treatment of TIA involves medication and surgery.

To avoid TIA or a stroke in the future, one has to maintain a healthy lifestyle, do some yoga, or exercise on a basic level.

What is Stroke?

A stroke is a medical condition in which the blood flow from the heart to the brain is interrupted.

And since the brain doesn’t get enough blood and oxygen, the brain cell tissues start dying due to which the functions that these cells control are affected, and the body collapses causing a stroke.

A stroke needs immediate medical attention as if not treated on time, it can be life-threatening. A stroke differs from low to high. The symptoms of the stroke include paralysis or numbness of the body.

A stroke is commonly known as ischemic stroke. Mostly, a blood clot interrupts the flow of blood in an artery which leads to the brain. A stroke can last for hours and so it leaves permanent damage to the body.

And it is fatal as it cannot be cured completely. Medication and surgery can control it but cannot cure it. Though, nowadays there are better options and treatments to treat stroke. Stroke can leave paralysis which will need physical therapy to recover.

The effects of the stroke can show improvement over time though there will always be a chance of having another attack. A stroke can grow larger causing swelling n the brain.

So, a stroke needs complete medical attention and monitoring. Stroke is a common disease, more than one million cases are recorded per year in India.
