Effects of Ketamine on Mentalizing and Metacognition in Healthy Volunteers
Ketamine-Induced Psychotic DisorderSocial Cognition1 moreAntipsychotic medication shows generally good effect sizes when looking at reduction of positive psychotic symptoms of schizophrenia, such as paranoia or delusion. However, social functioning often remains deficient in patients, meaning dopamine-receptor antagonists are not sufficient in treatment of people with schizophrenia. A naturalistic video-based paradigm, named MASC has been used in the past to model over- and undermentalizing in patients with autism spectrum disorder and schizophrenia, since deficits in mentalizing can be explained by either overinterpreting a social situation (e.g. paranoid thoughts about intentions of others towards self) or by lacking the skill to read intentions of others. To find out whether experimental manipulation via a non-competetive N-methyl-D-aspartate antagonist can induce difficulties with social cognition similar to those observed in people with schizophrenia, the investigators will conduct a RCT applying either ketamine or a placebo intravenously while participants are completing the above mentioned mentalizing task in the fMRI-scanner.
The Effect of Psychoeducation Given In Psychiatry Day Hospital
Chronic Mental DisorderPsychoeducationBackground: Psychoeducation is a process used in the realization of the principles of treatment and rehabilitation of mental illnesses and aims to help the patient and his/her family outside the hospital, to help the patient cope with the problems, experiencing, and to support them to live productive lives in society. Aims: This study aims to determine the effect of psychoeducation, given in a psychiatry dayhospital, on patients' self-sufficiency and well-being. Methods: The research is a single-blind randomized controlled experimental study. The sample of the study consisted of 28 schizophrenic patient(14experiment-14control), who agreed to participate in the study, followed in XXX University Psychiatry Day Hospital. In the study, an 8-week psychoeducation program was applied to the experimental group, and no intervention was made tothe control group. Socio-demographic data form, self-sufficiency scale, and well-being scale were used as data collection tools. The data obtained were analyzed using theSPSS-23 package program. Results: After the eight-week psychoeducation program, the pretest and posttest scores of the evaluations obtained from the scales of both groups were compared. It was found that while there was no change in thescores of the control group, there was an increase in the well-being and self-efficacy scores of the experimental group. While the increase in well-being was statistically significant(p<0.05), the increase in self-sufficiency score wasnot statistically significant(p>0.05), but the numerical increase was considered tobe aclinically significant result.
Museum-based Group Art Therapy in Mental Health Recovery
PsychosisThis clinical trial aims to evaluate the effects of an art therapy intervention carried out in museums to facilitate the process of recovery in mental health. In total 100 users of mental health services will be recruited for this study. Participants in the trial will be assessed at baseline and at 3 months.
Cannabis, Schizophrenia and Reward: Self-Medication and Agonist Treatment?
SchizophreniaDual Diagnosis2 moreIn this translational research proposal, based on our formulation, we seek to confirm and expand upon data obtained in our pilot study suggesting that cannabis and the cannabinoid agonist dronabinol, given in low dose to patients with schizophrenia and co-occurring cannabis use disorder, will in fact ameliorate the brain reward circuit dysregulation in these patients and, thereby, provide evidence in support of the role of cannabis as a "self-medication" agent for them.
A Shared Decision-making Training for Inpatients With Schizophrenia
SchizophreniaSchizo-affective Disorder"Shared decision-making" is being promoted as a promising approach for engaging patients with schizophrenia in medical decisions and improving satisfaction and adherence. To implement shared decision-making, both physicians and patients should commit to it and engage in a mutual decision process. Most research, however, has addressed interventions that either focus on the doctors' side (e.g. "communication skills") or on informing patients about treatment options (e.g. "decision aids"). These approaches have been shown to be feasible in clinical practice but had no strong effects on treatment patterns or adherence, possibly because they were insufficient to motivate and enable patients to engage actively in decision-making. Moreover, these interventions still rely on the doctor's willingness to share decisions, which has been shown to vary considerably. To overcome these limitations and since many patients do not feel competent to participate in decision-making we developed an intervention that focuses on patients' communicative competencies. this intervention, a five session group-training, will be implemented for inpatients suffering from schizophrenia.
PTSD (PostTraumatic Stress Disorder) Services for Veterans With SMI (Severe Mental Illness)
Post Traumatic Stress DisorderSchizophrenia3 moreAs in the general population, there is no clear standard of care within Veterans Affairs Medical Centers for treating posttraumatic stress disorder (PTSD) among individuals with severe mental illness (SMI). This is a considerable issue because trauma, posttraumatic stress disorder (PTSD), and severe psychiatric comorbidity are particularly common among Veterans and this symptom presentation clearly exacerbates the overall course and severity of mental illness. This study is significant in that it proposes to establish the efficacy of a frontline exposure based intervention for posttraumatic stress disorder (PTSD), Prolonged Exposure, for improving critical clinical, quality of life, and cost outcomes among Veterans with severe mental illness (SMI) enrolled in VA healthcare. Collectively, it is anticipated that these data will establish a much needed clinical course of action for what is considered a vulnerable yet highly underserved patient population.
Acute Glycine Pharmacodynamic Study
SchizophreniaPsychotic DisordersThe purpose of this study is to use proton magnetic resonance spectroscopy (MRS) at 4 Tesla to measure brain glycine levels noninvasively at baseline and for 2 hours after a single oral dose of a concentrated glycine-containing beverage, and to compare MRS glycine measurements to glycine blood levels in samples obtained after each MRS spectrum. The investigators hypothesize that they will observe a high correlation between the magnitude increases in brain and plasma glycine levels over this time frame. The investigators also hypothesize that we will observe large intersubject variability in glycine uptake rates into brain and blood. The investigators also hypothesize that subjects with a glycine decarboxylase (GLDC) mutation (triplication) will have lower baseline plasma and brain glycine levels and will experience smaller brain and plasma glycine increases after glycine consumption than controls or family members without the GLDC mutation.
Decision Support for Smoking Cessation in Young Adults With Severe Mental Illness
Mental IllnessTobacco Smoking1 moreUp to 77% of young people with severe mental illnesses smoke, a rate that is up to five times higher than the rate of daily smoking in other young adults. Contrary to popular belief, smoking tobacco does not provide any benefit for mental illness symptom control. People with severe mental illnesses (SMI: schizophrenia and severe mood disorders) are dying, on average, 25 years earlier than those without SMI. Much of this early mortality is due to higher rates of heart and lung diseases, cancers, strokes, and diabetes. Cessation of smoking in these transition-age young adults can prevent cancer and increase life expectancy to that of non-smokers. Combination treatments are effective in this group and therefore key to improving outcomes, but few SMI smokers use them despite their interest in quitting. Motivational interventions for cessation increase interest in quitting, but public mental health clinicians do not deliver them, in part due to economic reasons. Thus cost effective methods to deliver motivational interventions to engage young smokers with SMI into treatment are needed. To address this gap, we have developed an electronic decision support system (EDSS) for smoking cessation that is specifically tailored for smokers with SMI, who tend to have cognitive deficits and limited computer experience. Similar to EDSSs developed for other health problems, this EDSS provides information and motivational exercises within an easy-to-use, web-based computer program that can be used with minimal or no staff assistance. Initial piloting of the EDSS in middle-aged SMI smokers showed excellent usability and promising efficacy. Pilot-testing among young patients suggested that the EDSS increased motivation to quit smoking and provided direction to adapt the format and content of the EDSS for young SMI smokers. The purpose of this proposal is to further develop the motivational decision support system and to test its ability to motivate young smokers with SMI to quit smoking with cessation treatment.
Improving Outcomes for Individuals With Serious Mental Illness and Diabetes
Diabetes MellitusBipolar Disorder3 moreThis project tests a model for improving illness self-management among persons who have both serious mental illness and diabetes and will be performed within a primary care setting at a safety net hospital system. The information gained from the randomized trial will be supplemented with reports from participants about their experiences of trying to improve illness self-management. Improvements in self-management should result in a reduction of psychiatric symptoms and improvements in functioning and physical health.
Cognitive Effects of Nimodipine in Patients With Schizophrenia
SchizophreniaSchizo Affective DisorderThis study aims to evaluate the acute effects of nimodipine on cognitive performance in patients with schizophrenia using a battery of cognitive assessments.The subjects will also complete a 30-minute structural and functional MRI scan, with the goal of linking brain activity with working memory performance. Investigators predict that the performance increase induced by nimodipine will be greater in subjects who carry the A allele for the Calcium Voltage-Gated Channel Subunit Alpha1 C (CACNA1C) risk single nucleotide polymorphism (SNP) (rs1006737) in comparison to the response of G carriers.
