Neurofeedback is an effective conjunct treatment for alcohol addiction as it helps regulate deficient brain wave patterns and pathological brain processes that are found in the brains of alcoholics. This in turn improves the symptoms of alcohol addiction.
It is generally considered safe without any significant side effects that resolve within 24-48 hours after the session. These can include mild headaches, sleepiness, anxiety, and lack of focus.
It depends on the severity of alcohol addiction that the person has as well as their response to the neurofeedback training sessions.
