Transient global amnesia (TGA) is a neurological disorder whose key defining characteristic is a temporary but almost total disruption of short-term memory with a range of problems accessing older memories.
Transient global amnesia (TGA) is an uncommon condition affecting about 1 in every 20,000 Americans, although as many as 1 of every 4,000 over age 50. Many TGA patients have a precipitating factor ...
Transient global amnesia is a well-described medical and clinical phenomenon. This form of amnesia is distinct in that abnormalities in the hippocampus can sometimes be visualized using a special form of magnetic resonance imaging of the brain known as diffusion-weighted imaging (DWI). Symptoms typically last for less than a day and there is ...
One morning, the two of them are walking home and cross paths with an elderly man (Massimo Girotti). He is suffering from transient global amnesia, remembering nothing about himself and his current situation, although recalling random episodes from his remote past. And despite Giovanna's protests, Filippo brings him back to their home for the ...
Amnesia is an abnormal mental state in which memory and learning are affected out of all proportion to other cognitive functions in an otherwise alert and responsive patient. [5] There are two forms of amnesia: Anterograde amnesia and retrograde amnesia, that show hippocampal or medial temporal lobe damage.
RA can also be an inherent aspect of other forms of amnesia, namely transient global amnesia (TGA). TGA is the sudden onset of AA and RA caused by a traumatic event, however it is short lived, typically lasting only 4 to 8 hours [ 51 ] TGA is very difficult to study because of the patients' quick recovery.

In neurology, anterograde amnesia is the inability to create new memories after an event that caused amnesia, leading to a partial or complete inability to recall the recent past, while long-term memories from before the event remain intact.
Transient global amnesia is a dramatic, sudden, temporary, near-total loss of short-term memory. Various causes have been hypothesized including ischemia, epilepsy, migraine [ 148 ] and disturbance of cerebral venous blood flow, [ 149 ] leading to ischemia of structures such as the hippocampus that are involved in memory.
