Neurofeedback is considered an evidence-based intervention.

The FDA recognizes that all interventions pose risks and benefits. Typically, the benefits of neurofeedback far outweigh the risks, although on occasion can result in non-serious adverse events, NFB falls under the category of other low risk activities such as progressive relaxation, hypnosis, breathing exercises, meditation, yoga and massage.

Training with neurofeedback can occasionally result in adverse response(s) that temporarily increases symptoms which are typically associated with relaxation and calming of the central nervous system such as fatigue, headaches, lightheadedness, dizziness, irritability, moodiness, weeping, insomnia, agitation, and difficulties with focus and anxiety. These reactions, if they occur, are temporary and typically only last 24-48 hours. Once clients/patients become more relaxed and aware, they tend to integrate past emotional issues and these symptoms subside.
