In my many years of experience, and in being trained in Special Education and working with Special Needs students in all grade levels, I have found that yes, disruptive students may have some type of learning disability and use their disruptive behavior to do either two things, seek attention or gain power or control over a situation, or in a negative way for avoidance of a situation (example, having to participate in a reading activity).

The best thing that the teacher can do is to go to their administrator and provide him or her with as much information as possible about the student. Additionally the teacher should look in the student's records submitted at the time of enrollment to see if there were reports made by other instructors about this behavior.
