Filter by:The purpose of this study is to evaluate the effectiveness of a visual remediation intervention for people with schizophrenia. The intervention targets two visual functions that much research has shown are impaired in many people with the disorder, namely contrast sensitivity and perceptual organization. The first phase of the study will test the effects of interventions targeting each of these processes, as well as the effects of a combined package. A control condition of higher-level cognitive remediation is included as a fourth condition. The second phase of the study will evaluate the effectiveness of the most effective intervention from the first phase, but in a new and larger sample of individuals. Outcome measures include multiple aspects of visual functioning, as well as visual cognition and overall community functioning.
Purpose and objective Schizophrenia is a chronic debilitating illness with cognitive deficits that cause serious impairment in psychosocial recovery and with few treatments to remediate these deficits. One area that holds great promise for the development of novel, effective therapies is noninvasive brain stimulation. The investigators have used one form of brain stimulation, transcranial magnetic stimulation (TMS), for some time to modulate and enhance cognitive function in the brain, especially working memory (WM) function, which has a central role in most executive processing that occurs in the brain. Theta burst stimulation (TBS) is a paradigm of TMS which has been shown to effectively modulate WM. Moreover, TBS can modulate gamma neural oscillations in the brain and neural activity, both of which have been implicated in the physiology of WM and pathophysiology of the disease process in schizophrenia, making these measures highly valuable for assessing physiological effects of TBS on cognition, quality of life and cortical inhibition. The purpose of this study is to evaluate the effect of TBS on WM in patients with schizophrenia, to develop evidence for potential brain stimulation techniques to treat cognitive deficits in schizophrenia. Study activities and population group: Study subjects will be inpatient schizophrenic individuals with minimal positive symptoms and predominant cognitive deficits at Duke University Hospital. In an initial session they will be screened and taught a WM task. Following this, one TBS session will follow in which TBS will target dorsolateral prefrontal cortex. They will perform the WM task before, with and after the TBS, with an expected pre-post enhancement of WM performance. Implications - There is a great need for treatments for cognitive deficits in schizophrenia. The results of this study will serve to generate pilot data for a much larger grant to develop a TBS therapy for remediating such cognitive deficits.
Cognitive-behavioral therapy (CBT) and social skills training (SST) are recommended psychological interventions to improve symptomatology and functional recovery in psychosis. In addition, CBT may reduce hyperactivation of the brain structures responsible for the stress response. In patients with early onset psychotic disorder (EOP) there are not any previous controlled study that has analyzed the efficacy of this type of intervention. The aim of this study is to investigate efficacy of CBT + SST in symptomatic and functional improvement after the treatment in patients with EOP. The study will also examine the potential effect of the intervention on neurobiological stress markers.
This randomized clinical trial compares the influence of joint crisis plans (JCP) or crisis cards to reduce psychiatric coercion for people with severe and often recurring mental illnesses like schizophrenia, bipolar disorder or schizoaffective disorder. Both interventions will be carried out as an integrated part of otherwise standard psychiatric in-patient and out-patient care in psychiatric units specializing in the acute or non-acute treatment of mentioned mental illnesses.
The principal objective of this pilot trial is to evaluate the effectiveness of a psychosocial intervention to reduce self-stigma and improve treatment adherence and quality of life among people with a severe mental illness who attend to Community Mental Health Centers in Chile. The intervention is based on recovery and narrative therapy and considers 10 group sessions, mainly with patients, but also integrating relatives and professionals in some of the activities.
This clinical trial will test a combined group therapy plus mobile cognitive behavioral therapy intervention targeting defeatist attitudes in consumers with schizophrenia in order to change motivational negative symptoms linked to defeatist attitudes.
The purpose of this study is to determine whether cognitive training exercises can improve cognitive functioning in young patients with recent-onset psychosis who are being treated in community mental health settings using the NAVIGATE model. The investigators will examine the effects of web-based cognitive training exercises delivered on iPads. Participants will be randomized to one of three conditions, and will be assessed at Baseline, Post-Intervention, and 6 Month Follow Up on measures of clinical, neurocognitive, and functional status.
Clozapine has consistently shown to be a superior drug for psychosis in patients who do not respond to other treatments, but its mechanism of action remains unknown. The overall goal of this study is to examine the functional neural circuitry that underlies successful treatment with clozapine, which may lead to the identification of biomarkers that will allow for more efficient use of clozapine, as well as additional treatment targets for patients with refractory illness.

Cognitive deficits are some of the most prominent and disabling symptoms of schizophrenia. Evidence suggests that schizophrenia involves alterations to the functioning of a neural system under the control of a brain chemical called GABA. The present project will compare the effects of low-dose clonazepam (at a sub-sedating dose) to placebo, for effects on GABA- modulated brain activity measured by EEG, and associated cognitive processes in people who have schizophrenia.
