[Neurofeedback as ADDH therapy].

The article is a review of the past two decades of research on Attention Deficit Hyperactive Disorder (ADHD) and the documented effect of training with EEG biofeedback, often called neurofeedback. Research during the past twenty years seems to confirm that 70-80% of patients benefit from neurofeedback training. Research from the last ten years, using control groups, comparison between different kinds of treatment and psychometric testing, has to some degree confirmed the early findings. Due to the lack of placebo studies or studies comprising false feedback, neurofeedback can only be characterized as probably effective.
