Seventy-one patients with recurrent migraine headaches, aged 17-62, from one neurological practice, completed a quantitative electroencephalogram (QEEG) procedure. All QEEG results indicated an excess of high-frequency beta activity (21-30 Hz) in 1-4 cortical areas. Forty-six of the 71 patients selected neurofeedback training while the remaining 25 chose to continue on drug therapy. Neurofeedback protocols consisted of reducing 21-30 Hz activity and increasing 10 Hz activity (5 sessions for each affected site). All the patients were classified as migraine without aura. For the neurofeedback group the majority (54%) experienced complete cessation of their migraines, and many others (39%) experienced a reduction in migraine frequency of greater than 50%. Four percent experienced a decrease in headache frequency of < 50%. Only one patient did not experience a reduction in headache frequency. The control group of subjects who chose to continue drug therapy as opposed to neurofeedback experienced no change in headache frequency (68%), a reduction of less than 50% (20%), or a reduction greater than 50% (8%). QEEG-guided neurofeedback appears to be dramatically effective in abolishing or significantly reducing headache frequency in patients with recurrent migraine.
"In their study, patients receiving music therapy plus standard care showed greater improvement in depression symptoms than those receiving standard care only. Neurofeedback has been found to be effective in producing significant improvements in medical conditions such as depression (Kumano et al., 1996; Rosenfeld, 2000; Hammond, 2004), anxiety (Vanathy et al., 1998; Kerson et al., 2009), migraine (Walker, 2011), epilepsy (Swingle, 1998), attention deficit/hyperactivity disorder (Moriyama et al., 2012), alcoholism/substance abuse (Peniston and Kulkosky, 1990), and chronic pain (Jensen et al., 2007), among many others (Kropotov, 2009). For instance, Sterman (2000) reports that 82% of the most severe, uncontrolled epileptics demonstrated a significant reduction in seizure frequency, with an average of a 70% reduction in seizures. "
[Show abstract][Hide abstract] ABSTRACT: We introduce a new neurofeedback approach, which allows users to manipulate expressive parameters in music performances using their emotional state, and we present the results of a pilot clinical experiment applying the approach to alleviate depression in elderly people. Ten adults (9 female and 1 male, mean = 84, SD = 5.8) with normal hearing participated in the neurofeedback study consisting of 10 sessions (2 sessions per week) of 15 min each. EEG data was acquired using the Emotiv EPOC EEG device. In all sessions, subjects were asked to sit in a comfortable chair facing two loudspeakers, to close their eyes, and to avoid moving during the experiment. Participants listened to music pieces preselected according to their music preferences, and were encouraged to increase the loudness and tempo of the pieces, based on their arousal and valence levels. The neurofeedback system was tuned so that increased arousal, computed as beta to alpha activity ratio in the frontal cortex corresponded to increased loudness, and increased valence, computed as relative frontal alpha activity in the right lobe compared to the left lobe, corresponded to increased tempo. Pre and post evaluation of six participants was performed using the BDI depression test, showing an average improvement of 17.2% (1.3) in their BDI scores at the end of the study. In addition, an analysis of the collected EEG data of the participants showed a significant decrease of relative alpha activity in their left frontal lobe (p = 0.00008), which may be interpreted as an improvement of their depression condition.

"Walker has reported on mild closed head injury (Walker, Norman, & Weber, 2002), anxiety associated with posttraumatic stress (Walker, 2009), migraine headaches (Walker, 2011), enuresis (Walker, 2012a), dysgraphia (Walker, 2012b), and anger control issues (Walker, 2013). His qNF protocol development centers on tailoring the protocol to the individual clinical and qEEG data, with some restrictions of either increasing or decreasing the amplitude of certain frequency ranges.

[Show abstract][Hide abstract] ABSTRACT: While there are literature reviews and meta-analytic coverage of neurofeedback (NF) studies that focus on traditional amplitude NF and slow cortical potential NF, the same is not true for quantitative electroencephalographic (qEEG)-guided NF (qNF). To that end, this is a literature review of several qNF research articles. Generally, most are found in clinical settings, address a wide variety of symptoms and diagnoses, use clinical assessments as outcome measures, employ individualized NF protocols based on qEEG findings, and define efficacy in terms of improvement on pre-post outcome measures. However, few report pre-post qEEG metrics as outcome measures. Suggestions for future research are presented.

[Show abstract][Hide abstract] ABSTRACT: The purpose of this study was to identify the effects of Neurofeedback(NF), Cranio-Sacral Therapy(CST) and Combine Therapy(CT) in middle aged women through their experiences after participating these therapies. The participants were 53 middle aged women who lived in S city, 17 in the NF group, 17 in the CST and 19 in the CT, for 10 weeks from October to December, 2007. The NF group had 30 sessions, the CST group had 10 sessions and the CT group had 30 sessions of NF training after 10 sessions of CST. The data was collected from daily chart by self reporting their experiences during sessions. Collected data was analyzed by content analysis. From raw data, 37 items of NF, 91 items of CST and 110 items of CT were extracted in the content analysis. Similar items were gathered to 22 attributes of NF, 63 of CST and 68 of CT. These attributes were categorized into 9 higher attributes. The dominant attributes of NF were doziness during the training, mental comfort, lightening of physical and mental condition. Mental and physical comfort, improvement of sleep, healthy condition, crying were the dominant of CST. Also mental and physical comfort, lightening of physical condition, improvement of sleep, tear were the dominant of CT. According to the results of this study NF, CST and CT were very effective on physical and psychological relaxation. Therefore it is recommended that these NF, CST and CT be used as a complementary and alternative medicine(CAM) in middle aged women.
