There has been a lot of positive results treating Autism coming out of neuralfeedback therapy. Children on the spectrum who are set up with a device to turn EEG patterns into signals that can be used to control avatars in a game have over time shown marked improvement in speech, social interaction, and general state of well being. This is a form of cognitive therapy that is thought to enable the child to have a frame of reference or a feedback loop for their mental state that would otherwise be unavailable to them providing them the ability to become aware of it and learn to control it.
