Brain damage CAN alter a person's personality drastically...
To everyone ehre who's complaining about McAdams being so difficult to deal with after her accident, you need to realize something:
Head injuries that result in brain damage CAN alter someone's personality. Such injuries NEVER fully recover, and some damage is never healed. And if the brain areas that deal with behavior and personality were compromised, then that person will NEVER be the same, even if the memory IS intact.
So it's not that much of a strech to see an apparently sweet and easygoing person turn into a difficult immature thin skinned b!tch.
I mean, take into consideration:
1- About good 5 years of her life were erased, meaning:
a) She's lost whatever skills she learned, so good bye current job.
b) Recent friends and mates now are strangers, so good bye recent relationships.
c) Like coming out of jail, everyone has moved on but you.
2.- She's not and will never fully recover, so there' some disability to stay with her.
3.- It seems her personality was compromised due to the brain damage. So forget about who she WAS, that person is forever gone.
Wouldn't you be also upset and resentful in her shoes? Being forced to relate to perfect strangers whom you LIKED yet are not sure you like NOW anymore, and trying to pierce together what's left of your life?
I'm surprised she wasn't even harder to deal with.
