Filter by:The aim of this study is to compare the effects of a new psychological therapy, Avatar Therapy, to the current standard therapy, Cognitive Behavioural Therapy (CBT), in improving outcomes in people living with psychotic disorders who have persisting experiences of hearing voices (auditory verbal hallucinations, AVHs).
One hundred schizophrenia patients with auditory hallucinations will be recruited and randomized into group A and group B. Participants of group A will firstly receive a speech competition training for 2 weeks, and those in group B will firstly receive music intervention as placebo treatment. Specifically, speech competition training include voice competition training twice a day in adjunction with drug treatment, and the patients will be required to perform voice-related tasks according to the instruction. The reaction time, accuracy rate and the number of auditory hallucinations during the task will be recorded. On the other hand, the placebo treatment includes soothing music twice a day for a fixed period of time while patients receiving drug treatment. After 2 weeks, the interventions for group A and group B will be switch. Clinical symptoms will be evaluated using the auditory hallucinations rating scale, positive and negative syndrome scale, belief about voices questionnaire-revised at baseline, 2-week follow up and 4-week follow up. All the data will be analyzed with the Statistical Product and Service Solutions(SPSS) software.
This study explores the feasibility, acceptability, and effectiveness of four imagery intervention techniques (metacognitive imagery intervention, imagery rescripting, promoting positive imagery and competing imagery task) for auditory vocal hallucinations using four single case series with an A-B-A within subject design.
Neurofeedback intervention aimed to regulate the superior temporal gyrus (STG) activation and default mode network (DMN) connectivity as well as to reduce the auditory hallucinations (AH) schizophrenia patients with medication resistant AH.
Auditory verbal hallucinations (AVH) are prevalent among patients with psychiatric disorders. Not only being highly stressful and functionally impairing, AVH often persist despite treatment. Recent attempts to treat AVH with add-on repetitive transcranial magnetic stimulation (rTMS) when targeting the temporoparietal junction (TPJ), a language node in the brain, has gained limited success. The aim of this investigation is to reduce AVH with rTMS using continous theta-burst stimulation over a novel target, the supplementary motor area (SMA), in participants with frequent AVH, while also assessing potential neurophysiological mechanisms underlying the symptom.
The purpose of this study is to address the shortcoming in clinical hallucination research by causally manipulating the neural loci of conditioned hallucination task behavior in-person in patients with psychosis using transcranial magnetic stimulation (TMS), tracking the impact of this manipulation on the number of times participants with hallucinations report hearing tones that were not presented. With such a causal intervention, the veracity of this explanation of hallucinations will be either validated or disconfirmed. If validated, the task can be further developed as a biomarker for predicting the hallucination onset, guiding, developing or tracking the effects of treatments for hallucinations.
Connection to Environment with Cognitive Therapy (CONNECT): A Single-Case Experimental Design Exploring Dissociative Experiences and Voices Emerging empirical evidence has suggested that dissociation is a robust determinant of voice-hearing in psychosis, and that dissociation mediates the link between trauma and voices. Despite the emerging evidence-base, targeted therapeutic interventions focusing on dissociation remain largely untested. The aim of the current study is to investigate whether targeting dissociation leads to improvements in distressing voices in people with a history of trauma. This will be done by delivering an eight session intervention called 'CONNECT' to six individuals within the Glasgow Psychological Trauma Service (GPTS) who hear voices, have experienced trauma and are dissociating. The intervention will focus on learning strategies to manage dissociation. It is hypothesised that reduced levels of dissociation will be associated with reduction in the frequency and distress associated with hearing voices. This study will use a randomized multiple baseline single-case experimental design, meaning that participants will be randomly allocated to a baseline of two, three or four weeks and then will begin eight weeks of Connection to Environment Cognitive Therapy (CONNECT). As well as daily measures during baseline and intervention phases, there will be four assessment points (baseline, pre-intervention, post-intervention and follow-up). The study will take approximately three months plus follow-up one month after therapy ends. Individual levels of dissociation and voices will be compared during baseline and intervention periods using visual analysis and Tau-U. This study will contribute to the evidence-based for dissociation interventions targeting distressing voices among this population. It serves to investigate the proposed mechanism in a clinical population using a therapeutic intervention. It will therefore inform clinicians of the effectiveness and feasibility of using such strategies in clinical practice and may have good generalizability to practice.
This is a randomized, placebo controlled, double-blind clinical trial. The investigators aim to examine the safety and efficacy of repeated transcranial magnetic stimulation (rTMS) for the treatment of auditory verbal hallucinations (AVH) in patients with schizophrenia who are not taking antipsychotic medication. The investigators employ a novel, accelerated protocol with only four sessions of low-frequency rTMS in one day. The effects of this accelerated protocol will be compared to the sham stimulation. Additionally, the investigators will examine the effects of rTMS on a neurophysiological level by evaluating mechanism of action in the temporo-parietal lobe by means of functional magnetic resonance imaging.
This is a 4 week therapeutic pilot study with a 4 week follow-up period involving inpatients with treatment resistant DSM-IV schizophrenia or schizoaffective disorder diagnosis. Each eligible subject will receive either 20 minutes of active tDCS (transcranial direct-current stimulation) or sham stimulation twice a day on 5 consecutive weekdays for 4 weeks with a 4 week follow-up period.
Occurrence of visual hallucinations (VHs) in schizophrenia depend in part on disorders in the processing of late visual information (Top-Down). The broader question of how these top-down mechanisms (cognitive and / or emotional mechanisms) are involved in the occurrence of VHs remains to be specified and very few behavioral studies have so far been interested. The investigators propose to study the implication of Top-Down mechanisms in the visual hallucinatory manifestations, more specifically in the processing of ambiguous stimuli during an emotional priming task. Schizophrenia patients with VHs would have more false visual perceptions in the treatment of ambiguous stimuli than schizophrenia patients with auditory hallucinations or no hallucinations (AH/NH) and healthy controls.
