Transient global amnesia: Minor inconvenience or early warning sign?

Transient global amnesia (TGA) is a clinical diagnosis and is often a diagnosis of exclusion. However, despite the benign nature of this condition, it has been associated with underlying life-threatening medical conditions (e.g., myocardial infarction, dissecting aortic aneurysm, arrhythmias).
