There is no exact definition. It is possible to lose large chunks of
your memory and personality as a result of brain injury and still
remain you, i.e. feel that you are subjectively connected to previous
versions of yourself. But if the injury is bad enough that you
remember nothing of the past and people who know you don't recognise
you apart from your physical appearance, then you may as well be dead.
Things would be more complex if memories, personalities and the sense
of identity itself could be altered easily and discontinuously. On the
other hand gradual alteration might be OK, even if the end result is
radically different, since that is what happens as a person grows up.
