Biofeedback and neurofeedback have some major advantages over the traditional use of pharmaceutical medication. But as no method is perfect, they also have some disadvantages.

Disadvantages

Biofeedback and neurofeedback:

 require a well-trained clinician/coach. Unlike most medication, which can be used without the supervision of a medical professional, a biofeedback session won't be successful when the clinician does not know how to use the equipment or how to analyze and interpret the data;

 require dedication and motivation of the patient. Some clients may not be motivated to go through the ‘effort’ of working on their own health;

 take time. In order to be truly permanently effective, a good number of sessions (5 to 10 or even more for neurofeedback treatments) may be required;

 are not as well accepted as most pharmaceutical solutions. The ‘lobby’ promoting this health training method is still rather modest;

 are still not very widespread. The number of well-trained health professionals who can offer this method is increasing, but still rather limited.

Advantages

Biofeedback and neurofeedback:

 can truly help eliminate health problems that are stress-related or that have a major psychosomatic component, whereas medication mostly addresses symptoms;

 can assist in rehabilitation, incontinence and other areas as a complementary solution, applied along with therapy and medication;

 deliver persistent effects, as patients learn to apply the techniques in daily life, without needing equipment;

 have no known side-effects, so they are a low risk solution;

 educate people about their health and empowers them to take control. It shows the progress they are making, which is a strong motivating factor.
