Transient ischemic attack (TIA)
TIA is a short term obstruction or interruption in the blood flow to the brain. Signs and symptoms may resemble like a stroke but the patient recovers within 24 hours and has no deficit. TIA is a warning sign that the patient may be affected by stroke in future. So it is necessary to consult a physician.
