Medical procedures can trigger transient global amnesia (TGA), a temporary memory loss condition. Neurological and cardiac procedures are most frequently associated with TGA, with stress and pain as common predisposing factors.
Area of Science:
- Neurology
- Clinical Medicine
Background:
- Transient global amnesia (TGA) is a clinical syndrome of sudden, temporary memory loss and inability to form new memories.
- TGA episodes typically resolve spontaneously within hours.
Purpose of the Study:
- To investigate the association between medical procedures and transient global amnesia (TGA).
- To identify predisposing conditions for procedure-related TGA.
Main Methods:
- A literature search was conducted on PubMed using keywords related to TGA and medical procedures.
- Data from 49 articles, summarizing 89 cases of procedure-related TGA, were analyzed.
- Two cases of TGA following gastroscopy were also described.
Main Results:
- Cerebral angiography was the most common procedure linked to TGA (45 cases), followed by coronary angiography (10 cases) and general anesthesia (9 cases).
- Neurological procedures accounted for the majority of TGA cases (51.7%), followed by cardiac (19.1%) and anesthetic (12.4%) procedures.
Conclusions:
- Medical procedures are diverse triggers for transient global amnesia (TGA).
- Predisposing factors include Valsalva maneuvers, emotional stress, anxiety, and acute pain.
- Understanding procedure-related TGA is crucial for clinicians performing invasive medical interventions.

Amnesia
The severity and duration of memory loss vary depending on the type and underlying cause. Amnesia is classified into two main types: retrograde and anterograde.
Retrograde amnesia is marked by the loss of memories formed before the onset of the condition. Patients may recall distant past events but often forget those occurring shortly before the incident.
