Active clinical trials for "Brain Diseases"

VIRGIL is a monocentric interventional study aiming to investigate the effect of immersion in a virtual tilted room on modulation of the verticality representation (postural vertical [PV] and visual vertical [VV]), which in turn might affect body orientation (head and trunk). To this end, the investigators will conduct a within-person randomized trial including post-stroke patients and healthy participants.

Pretransplant hepatoencephalopathy (HE) markedly impacts recipient outcomes after liver transplantation. Intraoperative CRRT showed benefits but feasibility was much concerned. This study aims to observe the effect on consciousness recovery when initiating CRRT early in the post-transplant period in recipients with ACLF and overt HE.

GRIN-related disorders encompass a new group of Inborn Errors of Metabolism according to the recent nosology published by Ferreira et al (Genet Med, 2019). These rare conditions represent a subtype of paediatric encephalopathies leading to intellectual disability, hypotonia, communication deficits and motor impairment (Orphanet entries: 178469, 289266, 101685, for GRIN1, GRIN2A and GRIN2B, respectively). Mutations leading to glutamatergic hypotransmission can be potentially treated with L-Serine leading to significant clinical benefits in patients according to a pilot study published by our group (Soto et al, 2019). In our study, the investigators will include about 20 spanish patients older than 2 years of age, harbouring GRIN variants functionally anotated as loss-of-function pathogenic variants. The investigators will evaluate dose tolerability, efficacy of the treatment according to neurocognitive and motor scales, as well as the effects of L-serine in microbiome composition.

The effects and safety of Human cord blood mononuclear cell for delayed encephalopathy after carbon monoxide poisoning

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.

To compare effects of sedation for upper gastrointestinal endoscopy with propofol and midazolam on psychometric tests and critical flicker frequency (CFF) in cirrhotics

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.

Objective: Report manganese serum levels and mortality in encephalopathic patients. Patients and participants: Consecutive patients aged > 18 years, with hepatic encephalopathy and informed consent signed by their families. Interventions: Patients' clinical characteristics as well as biochemical tests of renal function, hemoglobin, glucose and albumin levels were obtained as well as a blood sample to analyze manganese levels with a graphite furnace atomic absorption spectrometer. Hypothesis: There is a difference in the manganese levels between male and female patients.

The study will be conducted in two phases. Phase A will evaluate the contribution of bacterial overgrowth and colonic inertia to development of Hepatic Encephalopathy (HE)in 50 ambulatory subjects with HE and hepatitis C cirrhosis. This phase will include a Screening and Evaluation Visit. Phase B will evaluate the effect of rifaximin on bacterial outgrowth and severity of HE in 20 of the subjects enrolled in Phase A who have a somewhat greater degree of encephalopathy. The purpose of this study is to evaluate the following: the relationship between bacterial overgrowth and the presence and severity of HE in patients with hepatitis C cirrhosis; the effectiveness and tolerability of rifaximin relative to placebo in treatment of HE associated with hepatitis C cirrhosis; the relationship between bacterial overgrowth and the presence and severity of HE before and after rifaximin treatment.

The purpose of this study is to determine whether targeted temperature management at 36.0˚C(TTM-36) in patients who remain unconscious after resuscitation from in-hospital cardiac arrest(IHCA) will reduce death and disability compared with fever control. For this purpose, the current pilot study will be undertaken to establish the feasibility, safety, and surrogate outcomes of hypoxic-ischemic brain injury in 60 patients who remain unconscious after resuscitation from IHCA. Eligible patients will be randomly assigned in a 2:1 ratio to either TTM-36(n=40) or conventional treatment group(n=20). Randomization will be performed with stratification according to initial rhythm (shockable vs. non-shockable).
