Filter by:Neurofeedback can be described as a form of biofeedback which is based on recording brain activity; usually by using scalp EEG. Neurofeedback has been used for 40 years as a therapeutic treatment for many neurological conditions including epilepsy, attention deficit hyperactivity disorder and also to improve mental performance in healthy subjects. Participants can "see" their brain activity via the EEG readings and receive positive feedback (visual or auditory) to help them consciously shape their brain waves into the desired patterns. sLORETA, which is speciliazed computer program to analyze EEG results, will be used in conjuntion with EEG to study the effect of neurofeedback on the brain activity of healthy subjects. In this study we will investigate the effect of neurofeedback training using sLORETA, which is a specific method to measure brain waves. We will measure the effect on both brain hemispheres both before and after neurofeedback training.
The aim of the study is: - Epidemiological/observational: investigating the presence of neuropsychological and electrophysiological alterations, suggesting a condition of minimal hepatic encephalopathy(and its behavioral correlates), in childhood and young adulthood affected by pre-hepatic portal hypertension due to portal vein thrombosis, even for implementing specific diagnostic protocols. - Interventional: collecting preliminary data on the effects of a probiotic, in order to implement a controlled clinical study.
The purpose of this study is to determine whether hepatic encephalopathy, measured through magnetic resonance imaging, electroencephalogram and neuropsychological evaluation adds prognostic information to patients who are waiting for liver transplantation. If this model improves mortality prediction this might be used in the future for organ allocation.
