Final answer:
Transient global amnesia (TGA) is characterized by sudden memory loss and confusion, but does not cause loss of personal information and identity. People with TGA have difficulty remembering new information as well as events that occurred prior to the onset of the amnesia.
Step-by-step explanation:
The correct answer is A. Loss of personal information and identity. This is not a characteristic of transient global amnesia (TGA). TGA is a temporary form of amnesia that is characterized by the sudden onset of memory loss and confusion. People with TGA typically experience anterograde and retrograde amnesia, meaning they have difficulty remembering new information as well as events that occurred prior to the onset of the amnesia.
For example, someone with TGA may not remember what they ate for breakfast that morning or the names of their family members, but they can still recall events from their childhood. TGA does not typically cause a loss of personal information and identity.
It is also worth noting that TGA does not affect learning ability, alertness, or motor and sensory function. These cognitive and physical functions are preserved in individuals with TGA.
