Case Report - Transient Global Amnesia
A 63-year-old, recently retired teacher was brought to the Accident and Emergency department by her husband. One hour earlier, she had telephoned him from the local gym where she had just finished her daily workout and said: "I don't know where I am. What's happening? Where am I?" Despite his reassurances, she had continued to repeat the same questions. On examination, she was disoriented in time and place, had no recollection for events of the previous week and was unable to retain new information - including the identity of the attending doctor. Besides the amnesia, there were no other neurological signs or symptoms. A CT scan of the head was normal. Over the following 6 hours, her memory deficit gradually resolved although she was left with a dense "gap" for the episode of transient amnesia itself and for the preceding trip to the gym.
