A review of research to the present date yielded eight studies, with a total of 150 participants: three randomized controlled trials, three quasiexperimental studies, and two case studies. Findings showed improvements in attention, memory, executive functioning, and self-reporting of symptoms. Studies also reported normalized quantitative electroencephalograms after neurofeedback. Additionally, there was an abstract for a poster presentation and an abstract from a sports concussion conference that supported neurofeedback for concussions and postconcussion syndrome, but due to the limited information in the abstracts these studies were not included.
