As you have noticed, there is a great deal of overlap between sensory integration disorder and Asperger's Disorder. Indeed, a large number of children with Asperger's have sensory problems. They often have sensory difficulties with different kinds of sounds and textures, which often leads to a concurrent diagnosis of Asperger's and sensory integration. It is difficult to know whether your son qualifies for a diagnosis of Asperger's because a thorough assessment including interviews, cognitive tests, and completion of rating scales is required. However, the diagnosis isn't as important in this case because the treatment and management of Asperger's and sensory integration disorder are very similar.

In the case of you son, I think that you will need to designate more structure and limits to his video game use. You can explain to him that video games have caused a great deal of stress and strife in the home, so you will have to handle it differently from now on. I would suggest only allowing him to play video games for specified chunks of time (e.g., an hour) in which you will physically turn off the video console and TV at that time. You can post this new rule near the TV and provide warnings to him as the hour approaches (say at fifteen, ten, five, and two minutes). Then, you must follow through with the limit and turn the TV off. To ease the transition, you might think of some kind of small reward for him if he turns off the console and TV without argument. When the video game is off, he is advised to use this time to use the restroom, get a snack, rest. Depending upon your comfort level, he can turn the video game on again in thirty minutes or an hour.

In general, he will require warnings around transitions and lots of information about what to expect. Structure and limits are also very reassuring. These measures should reduce the frustration and anger that is typically a result of confusion or surprise about expectations being sprung on him.'

And, if you or someone in your family ever feels threatened, you should be open to the possibility that you may have to call the police for support. There is quite a bit of good information available to help educate law enforcement individuals on how to manage children and adults with developmental disabilities. This type of education helps to reduce the strain that can result when uninformed officers come into contact with individuals with special needs.
