Another one I recall was a young woman (18-19 years old) who had suffered a stroke or brain haemorrhage - seemingly related to lifelong epilepsy - and lost several years' worth of memories due to the effect on her brain. She said it had given her a lot more confidence, she had started out as overweight and shy but after losing her memories lost a lot of weight and became a gothy "alternative" model. But was sad she would never get those memories back and spent hours a day writing in a diary in case she should forget anything, it was quite sad
