Because the cause of transient global amnesia is unknown and the rate of recurrence is low, no standard approaches for preventing the condition exist. If your episode of transient global amnesia followed a particular activity, such as a strenuous workout or a vigorous swim in a chilly lake, talk with your doctor about what's safe going forward. He or she may recommend that you limit or avoid the activity that seemed to trigger your memory loss.
