Why aren't the neurological deficits associated with transient ischemia attacks permanent?

Transient ischemic attacks (TIAs) result from temporary disruptions in blood flow to the brain, leading to brief neurological deficits. These deficits are not permanent because the brain tissue typically does not suffer lasting damage during the short duration of ischemia. Once normal blood flow is restored, brain cells can recover, and function returns. Additionally, the brain has a remarkable ability to adapt and compensate for temporary disturbances in blood supply.
