The main symptom of transient global amnesia is being unable to create new memories and remember the recent past. Once that symptom is confirmed, ruling out other possible causes of amnesia is important. You must have these signs and symptoms to be diagnosed with transient global amnesia:  Sudden onset of confusion that includes memory loss, seen by a witness Being awake and alert and knowing who you are, despite memory loss Normal cognition, such as the ability to recognize and name familiar objects and follow simple directions No signs of damage to a particular area of the brain, such as being unable to move an arm or leg, movements you can't control, or problems understanding words  More symptoms and history that may help diagnose transient global amnesia:  Symptoms lasting no more than 24 hours and generally shorter Gradual return of memory No recent head injury No signs of seizures during the period of amnesia No history of active epilepsy  Another common sign of transient global amnesia due to the inability to create new memories includes repetitive questioning, usually of the same question — for example, "What am I doing here?" or "How did we get here?"
