And about six weeks prior to this hospitalization, she underwent repeat percutaneous transluminal balloon angioplasty of the left superficial femoral artery and popliteal artery. She had undergone multiple endovascular interventions in the past. She presented with symptoms of very short distance claudication in the left lower extremity and pain at rest in the left foot. Our patient was a 75-year-old woman with a past medical history significant for peripheral arterial/vascular disease with atherosclerosis and ischemia for which she took aspirin, clopidogrel, and simvastatin atrial fibrillation managed with sotalol stage two chronic kidney disease for which she took furosemide hypertension managed with lisinopril and anxiety managed with citalopram 20mg/day. Anterograde amnesia gradually diminishes within the course of a few hours and patients return to their baseline status, though they may retain a dense amnesic gap for the duration of the episode. 3 It typically affects patients between 50 and 80 years of age, at an average age of 61. The incidence of TGA is approximately 2.9 to 10 people per 100,000 worldwide. 2 Episodes last for a mean duration of approximately six hours. Neuroimaging studies performed after an episode of TGA display transient alteration of the specific hippocampal circuits that contribute to the creation and storage of memories. Transient global amnesia (TGA) is a clinical syndrome that was established by Hodges and Warlow in 1990. Results from imaging and epidemiological studies have recently revealed distinctions that enable differentiation between various transient amnesic syndromes as well as important clues to their underlying pathophysiologies. Transient amnesic syndromes are clinical phenomena that occur commonly in acute medical settings.
