A 14-year-old-girl developed sudden amnesia upon study for semester examination. She was using cellular phone texting when he realized amnesia and texted to her friend about the amnesia. On the captured texting messages, she showed grammatical errors and spelling errors. Diffusion-weighted brain MRI showed tiny lesions in left hippocampus consistent with transient global amnesia. EEG and other laboratory tests were normal. The amnesia recovered within 24 hours and did not recur during one and half year of follow up period.
