The underlying cause of transient global amnesia is unknown. There appears to be a link between transient global amnesia and a history of migraines, though the underlying factors that contribute to both conditions aren't fully understood.

Some commonly reported events that may trigger transient global amnesia include:

  • Sudden immersion in cold or hot water
  • Strenuous physical activity
  • Sexual intercourse
  • Medical procedures, such as angiography or endoscopy
  • Mild head trauma
  • Acute emotional distress, as might be provoked by bad news, conflict or overwork
