What is Amnesia?
5. Transient Global Amnesia
Patients with transient global amnesia (TGA) will find that they experience periods of feeling intensely agitated and/or confused. These attacks can last for hours and, once the period has passed, the patient will have little to no memory of what happened during that time.
Before the onset of the condition, the patient might begin to experience memory loss. We are not really sure of why transient global amnesia happens, but it is thought that it might be down to temporary blockages in the flow of blood to the brain. Another possible explanation is electrical activity in the brain similar to when seizures occur.
