Filter by:The purpose of this clinical trial is to investigate neural markers of target engagement to further develop auditory control enhancement (ACE) as a novel, inexpensive, and noninvasive intervention to address treatment-refractory auditory hallucinations. Here, we will address questions about the feasibility and acceptability of ACE, as well as the degree to which ACE results in measurable engagement of biophysical and neurophysiological targets. Participants will complete: - Auditory Control Enhancement (ACE): Participants will be assigned by chance (such as a coin flip) into one of two groups to receive a different dosage or level of transcranial direct current stimulation (tDCS) during three sessions of cognitive training. tDCS is used to stimulate the brain for a short period of time. For tDCS one or two thin wet sponges are placed on the head and/or upper arm. The sponges will be connected to electrodes which will deliver a very weak electrical current. The Neuroelectrics Starstim 32 will be used to deliver tDCS. - Interviews: Before and after ACE, in two separate sessions, participants will be asked questions about a) background; b) functioning in daily life and across different phases of your life and past, present and future medical records. - Cognitive Tests: During the interview sessions, participants will also perform cognitive tests. Participants will be asked to complete computerized and pen-and-paper tests of attention, concentration, reading, and problem-solving ability. - EEG scan: Participants will be asked to complete EEG (electroencephalography) studies before and after ACE training. EEG will be measured using the same Neuroelectrics Starstim 32 system used for tDCS. EEG measures the natural activity of the brain using small sensors placed on the scalp. These sensors use conductive gel to provide a connection suitable for recording brain activity. During EEG, participants will watch a silent video while sounds are played over headphones, or sometimes count the sounds. In addition to these auditory tasks, participants will also be asked to perform visual attention tasks, such pressing a button for a letter or image. - Magnetic Resonance Imaging (MRI) Scan: Participants will also be asked to complete MRI studies before and after ACE training. An MRI is a type of brain scan that takes pictures of the brain that will later be used to create a 3D model of the brain. The MRI does not use radiation, but rather radio waves, a large magnet and a computer to create the images. Researchers will compare individuals receiving ACE to those receiving sham tDCS during cognitive training to determine effects of ACE.
The study is a randomised, assessor-blinded parallel-groups superiority clinical trial, allocating a total of 266 patients to either the experimental intervention or standard intervention. The participants will be randomised to either 12-weeks of virtual reality therapy or supportive counselling. All participants will be assessed at 12- and 24 weeks post baseline. A stratified block-randomisation with concealed randomisation sequence will be conducted. Independent assessors blinded to the treatment will evaluate outcome. Analysis of outcome will be carried out with the intention to treat principles.
This randomized, sham-controlled, double blind, multicentre clinical trial aims at providing evidence for the efficacy and safety of continuous theta burst stimulation (cTBS) in the treatment of auditory hallucinations in patients with schizophrenia. Overall, the study will include 137 patients. Because of the adaptive study design, an interim analysis was performed after half of the originally planned patients (43/86), according to which the sample size was increased by 51 patients). Each patient will receive a three weeks course of daily (5/week) treatment; 50% of the patients will be treated with cTBS (1200 impulses daily), the other half with a sham stimulation to the left and right temporoparietal cortex. Sham stimulation will be applied by an active sham-coil that allows for a double-blind treatment. Follow-up assessments 1, 3 and 6 months after treatment will investigate the stability of treatment effects.
The aim of this study is to show presence of cognitive and emotional factors on the beginning and persistence of auditory hallucinations in non-psychotic children. Investigators will describe a significant link between this factors and hallucinations in a sample of non-psychotic children. The results of this sample will be comparing to another group of children of the same age, sex and diagnosis, but without hallucination. Finally, investigators will control the persistence of hallucination on the first group after a six month period.
The overarching goal of this project is to expand the traditional expertise in non-invasive neuromodulation at the University of Minnesota towards developing novel neuromodulation approaches using transcranial direct current stimulation (tDCS) for treating schizophrenia patients with medication-resistant auditory hallucinations. The investigators will use tDCS to stimulate prefrontal cortex. TDCS is a non-invasive brain stimulation technique that can modulate brain connectivity. Non-invasive brain neuromodulation will be combined (paired-neuromodulation) with training of a task that requires top-down control of auditory processes. Paired-neuromodulation can potentially be used as a therapeutic intervention to decrease auditory hallucinations in schizophrenia.
Investigating the effect of non-invasive transcranial current stimulation on auditory hallucinations in patients with schizophrenia. Normal neuronal activity is perturbed in schizophrenia, so selective targeting of this abnormal activity could serve as a treatment for schizophrenia and alleviate symptoms caused by abnormal neuronal activity, such as auditory hallucinations.
First clinical studies indicate an effect of repetitive transcranial magnetic stimulation(rTMS) in the treatment of auditory hallucinations (AH). However, effect size, optimal stimulation site and parameters are unclear. With this randomized, placebo-controlled clinical trial we test the efficacy and safety of bilateral continuous theta burst stimulation (cTBS), a patterned form rTMS, against auditory hallucinations. The treatment will be applied add-on to individual antipsychotic and behavioral therapy. Patients will be treated for 6 weeks each weekday (30 sessions) with 40s of cTBS (halfway between T3/P3 and T4/P4). For weeks 1-3, half of the subjects will be randomized to a sham-stimulation (coil tilted 45°). During weeks 4-6, all subjects receive real cTBS.
The primary outcome of this study is to evaluate the effects of low frequency subthreshold repetitive Transcranial Magnetic Stimulation applied to the left temporoparietal cortex of patients with refractory schizophrenia on the severity of auditory hallucinations. The secondary outcome is to evaluate the effects of the same rTMS protocol on quality of life, functionality and general psychopathology.
The purpose of this study is to determine whether trans Direct Current Stimulation (tDCS) is effective in the treatment of auditory hallucinations in schizophrenia.
Transcranial magnetic stimulation (TMS) involves the use of magnetic fields to non-invasively stimulate the brain. Studies overseas have suggested this may be an effective and safe treatment for auditory hallucinations in patients with schizophrenia. This is a sham-controlled, double-blind trial of TMS stimulation for the treatment of auditory hallucinations in patients with schizophrenia.
