Hi,
Treatments might include psychotherapy and clinical hypnotherapy as well as EEG biofeedback, a technique in which patients are trained to increase or decrease brain-wave activity in the parts of the brain related to their complaints. The EEG, which has been around for more than 90 years, is a map of the brain’s electrical activity and reflects a patient’s emotional and cognitive states.
I believe that your mum will respond well to EEG biofeedback training. EEG biofeedback or Neurofeedback is direct training of brain function, by which the brain learns to function more efficiently. It is totally safe, painless, non-invasive and no side effect.
