Transient ischemic attack
Make it clearer
A transient ischemic attack, or TIA, occurs when the blood supply to part of the brain is temporarily disrupted. Ischemic refers to reduced blood supply; transient means that the disruption does not persist.
It is usually caused by a blood clot that temporarily blocks a vessel supplying the brain. Picture a road that is blocked for a limited time and then opens again.
In brief
A transient ischemic attack is a temporary disruption in the blood supply to part of the brain.
It is usually caused by a blood clot that temporarily blocks a vessel supplying the brain.
A blockage interrupts blood flow for a time and then stops obstructing the vessel.
