Identifying Indices of Learning for Alpha Neurofeedback Training

Neurofeedback has been around for decades and has applications for both clinical and healthy populations yet there is no standard method for measuring learning or a way of defining successful learning. Thus the aim of this study was to focus on alpha neurofeedback and examine changes in three different measures: amplitude, percent time, and integrated alpha, across four methods: within sessions, across sessions, within sessions compared to baseline, and across sessions compared to baseline. Participants completed 10 weekly sessions of eyes open alpha (8–12 Hz) neurofeedback training (NFT) at Pz. Whilst all three measures showed changes within sessions, the inclusion of baselines revealed that such changes represented a return to baseline levels rather than an increase in alpha. Changes across sessions were only evident in amplitude and inclusion of baseline showed that NFT did not elicit any changes beyond baseline levels. Given this a case is made for incorporating baseline measures when attempting to identify evidence of learning. It is also suggested that both amplitude and percent time measures are used independently rather than incorporate them into a more conservative and less sensitive integrated measure. Finally, focusing on within sessions changes may be a more useful approach in identifying changes resulting from NFT.     

Neurofeedback Training for Tourette Syndrome: An Uncontrolled Single Case Study

Gilles de la Tourette syndrome (TS) is characterized by motor and vocal tic manifestations, often accompanied by behavioral, cognitive and affective dysfunctions. Electroencephalography of patients with TS has revealed reduced Sensorimotor Rhythm (SMR) and excessive fronto-central Theta activity, that presumably underlie motor and cognitive disturbances in TS. Some evidence exists that neurofeedback (NFB) training aimed at enhancing SMR amplitude is effective for reducing tics. The present report is an uncontrolled single case study where a NFB training protocol, involving combined SMR uptraining/Theta downtraining was delivered to a 17-year-old male with TS. After sixteen SMR-Theta sessions, six additional sessions were administered with SMR uptraining alone. SMR increase was better obtained when SMR uptraining was administered alone, whereas Theta decrease was observed after both trainings. The patient showed a reduction of tics and affective symptoms, and improvement of cognitive performance after both trainings. Overall, these findings suggest that Theta decrease might account for some clinical effects seen in conjunction with SMR uptraining. Future studies should clarify the feasibility of NFB protocols for patients with TS beyond SMR uptraining alone.

Neurophysiological and Psychophysiological Effects of Sulpiride in the Norm and in Patients with Opiate Addiction

We studied characteristics of the EEG activity and psychophysiological indices in healthy persons and patients with opiate addiction (in the states of abstinence and remission) before and after peroral introduction of 200 mg sulpiride. In the initial state, spectral characteristics of EEG in patients with opiate addiction differed from those in the control (in healthy tested subjects) by higher relative powers of low- and high-frequency components (delta and beta waves) and a considerable depression of the alpha rhythm. Treatment with sulpiride evoked changes in the spectral characteristics of EEG, which showed a significant intergroup specificity; intensification of alpha oscillations was a general effect in all groups. We conclude that the effects of sulpiride on the EEG activity comprised components typical of both neuroleptics and antidepressants; in the group of patients in the abstinence state, the pattern of effects of sulpiride was close in its profile to the effect of anxiolytics. Dynamics of the indices of psychophysiological testing after sulpiride treatment demonstrated that the drug exerts mostly positive regulating effects on the state of higher nervous functions in patients with opiate addiction.     

Some Ingredients for Mental Health

When the body is ailing the mind is soon impaired. Good health practices contribute to longer and better life. A balanced life of work-rest-play is necessary to human health.Psychosocial stresses at any period of life may impair morale and productivity and increase the likelihood of physical or mental disease. Bereavement, separation, divorce, loss of friendship, retirement, loss of self-esteem and symbolic losses contribute significantly to mental and physical ill health. Social and psychological support systems are vital to mental health maintenance.Mature persons evolve principles, values, moral and ethical tenets, philosophic and religious ideals and special codes of conduct to give meaning to their lives. The basic needs of survival and procreation must be integrated with moral precepts relating to interindividual behavior so as to give a person a feeling of self-worth, which is an indispensable element in mental health.     

Follow-up of Cases of Opiate Addiction from the Time of Notification to the Home Office

Follow-up of 108 opiate addicts for a period of six to seven years showed that 35 were still being prescribed opiates, 25 were off drugs, 19 were dead, and for 29 it was not certain whether they were on or off drugs. Most patients who came off drugs did so in the first two years after notification to the Home Office. Clearly treatment is more likely to be successful if given early in the life history of the addict, when it is appropriate to give treatment based on withdrawal of drugs rather than substitution.
