When transient global amnesia first occurs, MRI does not show specific abnormalities. However, after a few days, MRI may show tiny dots in an area of the brain that is important in forming and retrieving memories (the hippocampus). The spots may represent small areas where blood flow is decreased, suggesting a possible cause of the amnesia.

Transient global amnesia (TGA) is a temporary loss of short-term memory without other signs of impaired cognition and with absent focal neurological signs. The diagnostic criteria include that the attack should have been witnessed, there was no seizure or head injury, and the symptoms resolve within 24 hours.

Magnetic resonance imaging (MRI) of the brain performed 48 h after the onset of symptoms demonstrated focal dot-like diffusion restriction in the right and left hippocampi . With this clinical history and characteristic MRI findings, a diagnosis of transient global amnesia (TGA) was made.

The spots may represent small areas where blood flow is decreased, suggesting a possible cause of the amnesia. Transient global amnesia (TGA) is characterized by anterograde memory disturbance of sudden onset that lasts for 1 to 24 hours. 1 Orientation in space and time is impaired while consciousness remains undisturbed. Objective: The risk of recurrence of new amnesia events in patients having previously experienced transient global amnesia (TGA) ranges between 2.9-23.8%.
