Transient Global Amnesia


Transient global amnesia

(TGA) is a sudden, temporary loss of memory. You may not be able to remember information or experiences from the recent past, or remember new information. For example, you may not know where you are or how you got there. You may not remember information you are told, and you may repeat the same questions. Your memory usually returns within 24 hours.

Other symptoms that may occur with TGA:

  • Headache
  • Dizziness
  • Nausea

Contact your healthcare provider if:

  • You develop new symptoms.
  • You have other episodes of amnesia.
  • You have questions or concerns about your condition or care.


There is no treatment needed for TGA. TGA usually does not cause permanent memory problems. Your risk of having another episode of TGA is low.

Follow up with your healthcare provider as directed:

Write down your questions so you remember to ask them during your visits.
