A transient ischemic attack occurs when blood flow to part of the brain is temporarily reduced or blocked. Its symptoms can closely resemble those of a stroke, including facial weakness, speech difficulties, numbness, and vision changes.
The symptoms may disappear quickly, sometimes within minutes. This can create a dangerous sense of reassurance: a person may assume that the problem has passed and no further action is necessary.
In reality, a suspected TIA requires urgent medical assessment. It can be a warning that the person is at increased risk of a future stroke, and identifying the underlying cause may help prevent a more serious event.
A medical team may investigate blood pressure, heart rhythm, cholesterol, diabetes, blood vessels, and other factors that influence stroke risk. Depending on the findings, treatment may include prescribed antiplatelet medication, anticoagulation for certain heart conditions, cholesterol-lowering medication, or procedures to address specific vascular problems.
These treatments are not appropriate for everyone, and medication should not be started independently based solely on a suspected TIA.

The distinction between a TIA and a completed stroke cannot reliably be made at home. Symptoms that resolve still warrant emergency evaluation because early treatment may reduce the risk of further complications.
Do not wait for a second episode before seeking help. Prompt assessment can identify treatable causes and provide an opportunity to reduce future risk.
