Abstract :
Transient global amnesia (TGA) is characterized by the abrupt onset of global amnesia, particularly anterograde
amnesia. The pathophysiology of TGA is poorly understood and it could be caused by various factors and be
associated with various diseases. We report a 58-year-old man who presented to the local emergency room with
TGA lasting for several hours. The patient had complete anterograde amnesia without a past medical history
of migraine or neurological findings. His systolic blood pressure on presentation was 220 mmHg, which was
immediately treated with intravenous calcium ion influx inhibitor. Other than global amnesia, there was no
evidence of neurological disturbance. Computed tomography and magnetic resonance imaging results were
unremarkable. After treatment of his hypertension, his amnesia resolved within 12 hours. Emergency department physicians may encounter TGA. Correct diagnosis of the condition depends on recognizing the disease.
