Speaking as one whose brain gets ahead of my mouth, leaving me sounding like an idiot at times, I'd ask her to clarify and I'd do it ASAP or else let it go.
My first assumption is she was trying to convey the thought that because your child is gifted and has disabilities, that she tried to say the opposite of what she said -- intending to mean that just because he is gifted he should not be disqualified to receive help for his disabilities.

Any other explanation doesn't make sense to me unless she's a putz.
