Two kids, each with a set of diagnosis and accompanying behaviors. Relatively mild behaviors that generally do not bother the rest of the class. The two students are deeply distracted by each other's behaviors to the point of getting deeply upset (also potentially affected by diagnosed conditions). For example, one kid silently fidgeting, distracting second kid on other side of the room, leading to second kid standing up screaming and kicking. If putting one in another room isn't an option nor is requiring student to "just not have those mild behaviors accompanying conditions", what can be done?
