Aspergers is considered a high functioning autism. My daughter was diagnosed when she was in the 1st grade. My advice to you is to have alot of patience with her. My daughter also is very smart but has high anxiety with Math and with testing. She is 12 now, some things have gotten better , some things have changed. Keep in contact with the school make sure her IEP has everything to accommodate her and don't be afraid to change it when ever you think things aren't working. I've even had to change teachers because they were not willing to go by the accommodations in the IEP and thought their way would work better. A teacher can not change things without consulting the parent and having a meeting. You are your child's advocate so don't let anyone try to push you around. Also keep in contact with your child's SPED teacher, they are the eyes and ears at the school. If you do it right, just about everyone at the school will know you and will know you are completely involved with your child. One more thing, getting calls from the school and getting notes will be an everyday thing especially at first.

I know this must blow your mind cause it blew mine when I was told almost the same words you have said.  My daughter is now 11 yrs old.  I was first told when she was about 7 yrs. old that she had brain damage.  Which was not the proper words for that dr. to use when he was telling me.  Then she was diagnosed with aspergers syndrome which made alot more sense when I did the research.  I was first told she only had a speech problem.  Then came ADHD then came OCD and tics.  I know this must be overwhelming but the only advice I can tell you is to do research yourself.  On the computer, books at the library and try not to deny because that will only make you crazier. research...research...research  that's about all I can say,,  Good Luck
