Question: 1 / 400

What is the difference between a stroke and a transient ischemic attack (TIA)?

A stroke resolves within hours, while a TIA causes permanent damage

A stroke causes permanent damage, while a TIA is temporary

The distinction between a stroke and a transient ischemic attack (TIA) primarily lies in the permanence of neurological damage associated with each condition. A stroke typically results from a sustained interruption of blood flow to a part of the brain, leading to the death of brain cells and resulting in permanent damage. This can arise from either ischemic causes, such as a blood clot, or hemorrhagic causes, such as bleeding in the brain.

On the other hand, a TIA is characterized by temporary blood flow disruption that does not result in lasting brain damage. The symptoms of a TIA, which can mimic those of a stroke, usually resolve within minutes to hours, and no long-term neurological deficits occur. Understanding this distinction is crucial, as TIAs often serve as warning signs for potential future strokes and require prompt medical evaluation and intervention to prevent more severe outcomes.
