My grandson, whom we homeschool, was 14, now 15, when he was diagnosed with Asperger Syndrome (Asperger's). I knew something was wrong / different about him from when he was about 18 months, when we started taking care of him most of the time. He had anger outbursts often. Cried easily. Caused much stress and problems in a family with only one child, and a grandchild at that. He has lived with us most of his life, so this seems like home to him. Still, the problems are there.
When he was about seven years old, our family doctor wanted to put him on ritilin, but we declined. I am glad we did, because it wouldn't have done any good. I have a nephew with severe ADHD, but I believe that he still has an autistic problem and needs more evaluation, now that he has slowed down.
ADHD and Asperger's are both on the Autism Spectrum. Asperger's is considered high-functioning autism.
My grandson started going to a therapist last fall, and she noticed the symptoms of Asperger's. We took him to the Psychiarist group that she recommended and they confirmed Asperger's. They have a counselor who specializes in Asperger's. She also has a son with Asperger's and a younger son with autism.
My grandson was put on Trileptal for his anger and for mood stabilization; it worked really well, though not completely. He was given Zoloft for anxiety. For our part, we had to learn what triggered his rages and what caused his anxiety. We also had to let some things go, like not make such a big deal over the fact that he wanted to eat only one thing all of the time, like peanut butter and honey, or pizza, or macaroni and cheese. He has a chocolate instant breakfast with his morning meds, so he gets a little more nutrition. Now that we have all made adjustments, life is SO much easier and actually enjoyable!
Aspies, as the people who have Asperger's are called, have problems with socialization, communication, learning, and more. They can also have other syndromes, like ADHD. They are very intelligent, especially about things that they love, although they cannot do everything well.
My grandson has a writing disorder, where he cannot put his own thoughts on paper, but he can dictate great stories to me about Bionicles and other things that he is interested in. He is great at the computer, but not good at athletics, except rollerblading, which he likes.
When your son gets homefrom school, he has used up so much energy during the day, trying to do work and be good, that he is tired and lashes out at anyone who crosses his path. Often that is a time to give him an undertanding hug and give him something quiet to do while he calms down, or just give him some space. You might suggest that he might need some alone time, since he has had so much stress to handle and be nice about at school.
You can learn more about Asperger's at http://www.aspergers.com/ You may find your son's behavior outlined very well there.
My grandson said that he needed love, respect, and understanding.
I hope the info will help you and give you hope. Your son is special. Work on the positives when you can. Let him know that he is special, give him lots of love and support, and lots of hugs. You also might consider homeschooling him, so that he can function and learn better, as well as be able to use the energy that he does have to be good and loving at home.
May your son and all of your family have great success, love, ... and peace. ahhhh!
