Abstract:
The cause of transient global amnesia (TGA) remains controversial. Focal cerebral ischemia, seizure, venous congestion, and migraine have all been proposed as underlying mechanisms. We describe a patient presenting with typical TGA who two days later developed a posterior circulation stroke due to basilar artery occlusion. He was treated successfully with intra-arterial thrombolytic therapy. Shortly thereafter, he had recurrent basilar artery thrombosis and jugular vein thrombosis, and was found to have a mucinous adenocarcinoma believed to be causing a hypercoagulable state. We believe this case supports the hypothesis that TGA can on occasion be caused by cerebral ischemia.

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.
