Does my brother have autism?

Hello, my dad thinks there might be something wrong with my 15 year old brother. He is super shy and does not look at anyone in the eyes. He walks really weird as if super clumsy and stiff. He has a hard time talking to people and really keeps to himself. He is really smart and does some programming and plays games like world of Warcraft all the time. When he was a little younger he had a little group of friends, but now I don't know if he has any. He played a little basketball at camp but was never really good at it.

I personally think he is really shy and just loves computers. My dad thinks he has autism or aspbergers (sp?) What do you guys think? Any help would be really great.

Hi, this could be anything. Only you know the most about your brother so i'd say hit the internet, find lots of information the symptoms he's having and you might find something. But you couldn't know for certain that's why, if it's possible you could have him evaluated by medical experts. There is really not much more to say because of the limited information you gave but the best thing is still, if you're really worried get him evaluated.
