Is it safe?

Understandably, the question is often asked, as the central nervous system is indeed highly complex and sensitive. In the United States, Neurofeedback has been approved by the Food and Drug Administration for reducing stress. This body is responsible for selecting safe and effective products to protect public health. Another argument in support of this is that no electric current is sent to the brain. Only pauses in the sound tell the brain about its functioning, or more specifically about turbulence or disturbances in its electrical functioning.

Note, however, that while many practitioners say that Neurofeedback has no side effects at all, I would not personally make that claim. After the initial sessions, patients can be more sensitive, more "emotionally fragile" and sometimes do not sleep so well for a couple of nights. Some patients already feel quite exhausted after 33 minutes of Neurofeedback.

One thing seems certain: these are temporary setbacks!

And if we compare these with the side-effects of analytical Neurofeedback which, remember, works on only one or two frequencies at a time, these temporary side effects appear to be much less severe and seem to be a sign of neural circuits being reorganised.
