If symptoms of neurologic dysfunction last more than 24 hours and complete recovery doesn't occur, what is this condition called?

The condition described is termed a Cerebrovascular Accident (CVA), commonly referred to as a stroke. A stroke occurs when there is an interruption of blood supply to the brain, resulting in lasting damage to brain tissue. The symptoms of neurologic dysfunction that persist beyond 24 hours indicate that there has been significant and potentially irreversible damage, which aligns with the characteristics of a stroke.

In contrast, a Transient Ischemic Attack (TIA) is characterized by temporary symptoms that typically resolve within 24 hours, often less than that, due to a transient interruption in blood flow. Chronic cerebrovascular insufficiency relates to long-term issues affecting cerebral blood flow but does not necessarily reflect the acute, sudden event typical of a stroke. Each of these distinctions underscores why the condition is classified specifically as a CVA when symptoms last longer than 24 hours without complete recovery.
