The attack lessens over a period of hours, with older memories returning first, and the repetitive fugue slowly lengthening so that the victim retains short-term memory for longer periods. This characteristic of TGA, where the length of time affected by retrograde amnesia shortens (i.e. older memories return first, followed by more recent ...
The person's short-term memory may appear to be normal, but the person may have a difficult time attempting to recall a past story, or with unrelated words, as well as complicated patterns. [46] Korsakoff's syndrome is unique because it involves both anterograde and retrograde amnesia.
