Answer

As the name implies, transient global amnesia symptoms are transient.

The mean annual recurrence rate is thought to be low (approximately 4-5%). However, in the study by Miller et al, the calculated recurrence rate could be as high as 24% over a lifetime depending on inclusion criteria. [9] These occasional recurrences usually involve no long-term morbidity or death.
