Is neurofeedback effective for treating ADHD?
Criticisms of neurofeedback
While some studies have shown promising results, critics point out that several of these studies had design flaws. Flaws in a study can make it hard to prove whether a technique is effective.
Many authors have called for further research. Some researchers have criticized neurofeedback as a moneymaking scam, while others have voiced concern about the lack of guidelines.
Authors of a 2016 study noted that, while neurofeedback is noninvasive, available evidence has not proven its effectiveness. In addition, they wrote:
“It is expensive, time-consuming and its benefits are not long-lasting. Also, it might take months to show the desired improvements.”
Is it safe?
Neurofeedback is nonintrusive, and proponents claim that it is safe.
However, adverse side effects can include:
- mental fatigue
- old feelings returning, for example in vivid dreams, before they disappear permanently
- dizziness, nausea, and light sensitivity in people who have experienced head trauma
