What is TIA and for what is it responsible?

TIA stands for Transient Ischemic Attack, often referred to as a "mini-stroke." It occurs when there is a temporary disruption of blood flow to the brain, leading to stroke-like symptoms that typically resolve within 24 hours. TIAs are significant because they serve as warning signs for potential future strokes, indicating the need for medical evaluation and intervention to reduce the risk of more severe cerebrovascular events.
