Summary

Transient global amnesia (TGA) has been described since the 19th century. It is characterized by an episode of anterograde and retrograde amnesia lasting less than 24 hours. During this episode patients are conscious and able to interact normally, but are typically distressed and repeat questions without remembering explanations. Despite progress in medical imaging, no cause for the condition has been proven. Prognosis is excellent and management centres on recognition and reassurance. We describe the epidemiology, pathophysiology, clinical features and management.
