A Case of Transient Global Amnesia Triggered by Sexual Intercourse

Transient global amnesia (TGA) is described as a sudden onset of anterograde and retrograde amnesia. In this case report, we present a case of a 52-year-old man who came to our hospital experiencing sudden-onset confusion and memory loss an hour after engaging in sexual activity with his wife. Before this, the patient had no previous medical history. Four hours following the event, a non-contrast computed tomography (CT) scan was performed and showed no signs of any intracranial pathology. In addition, T1-weighted and T2-weighted magnetic resonance imaging (MRI) was performed 13 hours following the incident and demonstrated punctate focus of restricted diffusion in the medial right temporal lobe in the region of the hippocampus. A diagnosis of transient global amnesia was made after other causes were ruled out. We present this rare case of transient global amnesia (TGA), highlighting sexual intercourse as a probable triggering component of the disease and demonstrating how crucial it is to rule out other severely morbid conditions before managing TGA.
