Q: I’ve heard that research is beginning to show that neurofeedback can be effective in treating trauma. How does it work?
A: Neurofeedback was first developed almost 60 years ago to help patients control epileptic seizures by learning to regulate their brain activity. In addition to seizures, mainstream neuroscience is now showing us that a wide variety of psychological disorders and severe emotional turmoil can be understood as firing mistakes in the electrical activity of the brain. Neurofeedback has developed into an increasingly sophisticated technology, which can teach people to make changes in their brain’s activity to eliminate symptoms of conditions including bipolar disorder, attention disorders, anxiety and phobia disorders, depression, autism spectrum disorders, personality disorders, and post-traumatic stress disorder (PTSD).
Wave frequencies in the brain underlie every thought and feeling we have, as well as the behaviors they give rise to. Typically, for example, when we make more alpha waves (the frequency of 8–11 Hz), we feel more relaxed and, with time and training, can learn to spend more time in relaxation states as our default mode of brain activity. If someone with attention deficit disorder needs to pay better attention, they can learn to make more beta waves (15–18 Hz) and get better at maintaining focus. Simply put, the neurofeedback practitioner—ideally also a psychotherapist—assesses the…
