I do not think you can break a mind permanently like that no. At best you can temporarily overwhelm, make the person maybe even briefly incapacitated as Barb says, maybe forget where, who, when, what they are and just be in intense pleasure, maybe also pass out into wonderful sleep after, and leave a nice lasting memory, to think back on, but that forgetting thing is not permanent, the memory can be though, and like any memory can alter what one seeks out again later, and how one feels etc.
That I think goes for pleasure and, for some, pain (those who enjoy and seek that out, and go into 'sub'space, though when it comes to that you probably need to ask someone who is into that).
