Yes. Neurofeedback is an operant conditioning procedure, meaning the brain is taught how to normalize through the delivery of rewards (positive reinforcement). If a person administering neurofeedback is not credentialed or skilled, and has not taken the proper assessment, such as a brain map and clinical interview, it is possible that a patient may feel overly tired or wired after a session. According to neurofeedback expert Dr. Frank Duffy, a neurologist at Children’s Hospital Boston, there are no known or documented significant side effects from neurofeedback. However, it is imperative that a client research their clinician’s competency by ensuring they have minimal credentials in the field of Neurotherapy.
