why is lily described as retarded and kent described as brain damaged?

someone explain this? to me lily was much more mentally ill than retarded, though i can see her having definitely been slow. rest in peace, lily.
and kent seems genuinely mentally retarded, but diligent and hard working, and not mentally ill.

why do some people describe him as "brain damaged"? where does that come from? i've never understood it.
