Howling:What happened to Donna

The Doctor said if Donna started to remember, her brain would overload and overheat and she would die. When she started to remember all she got was a bit overheated, a headache and then collapsed and went to sleep. And I find the defense mechanism funny, when I saw that scene in a preview I thought she would become a EMP type bomb, and she did. I would like to know why she didnt die.
