Chronic stress increased the value of CRP.[19,20] Earlier, it has been shown that biofeedback is effective for symptom reduction in some clinical conditions,[21] for example, pain,[22] epileptic seizures,[23] and attention deficit-hyperactivity disorder,[24] as well as for improving motor performance after stroke.[25] Bazanova et al[26] also showed a positive efficiency of neurofeedback with EMG training in ADHD children. The gene discussed is CRP; the disease is stroke disorder.
