She reportedly regained her memory after eight hours, and had no recollection of not remembering those things just earlier in the day.
Neurologist Peng Jiaxiong told Chinese media that it is possible to lose your memory from straining too hard.
He explained the phenomenon is called "transient global amnesia" and, in her case, happened due to the increase in abdominal and intra-cerebral pressure that caused a lack of oxygen flow to her brain. The result was short-term memory loss.
