In a large survey, 11% of individuals in a TGA state were described as exhibiting "emotionalism" and 14% "fear of dying". Although confusion is sometimes reported, others consider this an imprecise observation, but an elevated emotional state (compared to patients experiencing Transient Ischemic Attack, or TIA) is common. Though outwardly appearing to be normal, a person with TGA is disoriented in time and space, perhaps knowing neither the year nor where they reside. The individual experiencing TGA retains social skills and older significant memories, almost always including knowing his or her own identity and the identity of family members, and the ability to perform various complex learned tasks including driving and other learned behavior one individual "was able to continue putting together the alternator of his car." Also, during episodes of TGA, a person's personality remains intact and the episode is not associated with loss of consciousness, a decreased level of consciousness or cognitive deficits (other than memory impairment). One of its bizarre features is perseveration, in which the victim of an attack faithfully and methodically repeats statements or questions, complete with profoundly identical intonation and gestures "as if a fragment of a sound track is being repeatedly rerun." This is found in almost all TGA attacks and is sometimes considered a defining characteristic of the condition. A person experiencing TGA has memory impairment with an inability to remember events or people from the past few minutes, hours or days ( retrograde amnesia) and has working memory of only the past few minutes or less, thus they cannot retain new information or form new memories beyond that period of time ( anterograde amnesia). This onset of TGA is generally fairly rapid, and its duration varies but generally lasts between 2 and 8 hours.
