Filter by:The purpose of this study was to test the effects of resourcefulness group intervention on facilitating recovery and improving the quality of life in patients with chronic schizophrenia.
Objective: This study aimed to evaluate the effect of multiple occupational therapies on functional remission and subjective recovery of individuals with schizophrenic disorder. Methods: 26 people with schizophrenic disorder were divided into two groups using a random number table. The intervention group participated in routine community mental health center services and a total of 24 sessions of occupational therapies three times a week, while the control group participated in routine community mental health center services.
The goal of this clinical trial is to compare the effect of nutritional counseling versus no treatment in patients with schizophenia or bipolar affective disorder. The main question it aims to answer are: • Can nutritional counseling have a preventive effect on the development of cardiovascular disease in patients with schizophenia or bipolar affective disorder? Participants will meet a nutritionist at baseline to asess nutritional status, biochemical and anthropometric measurements. Then, half of the study population will receive nutritional counseling. After six weeks, the same baseline measurements will be repeated to examine any potential differences between the two groups. After the intervention, the control group will be offered the same counseling as the intervention group received during the study.
The goal of this double-blind, placebo-controlled randomized clinical trial is to test the effect of 12 weeks of orally administered MitoQ (mitoquinol mesylate) supplementation on cognition in 50 people with early phase schizophrenia-spectrum disorders (E-SSD) who have mitochondrial dysfunction (called high risk, or HR). Cognitive impairments in SSD can cause significant disability. Yet, there are no effective treatments for cognitive impairments in SSD. It has been shown that alterations in a certain type of brain cell (parvalbumin interneurons, or PVI) underlie cognitive deficits in SSD. These PVI, which fire at a fast rate, utilize high amounts of energy from the mitochondria and are highly vulnerable to oxidative stress. MitoQ is an antioxidant. Research has shown that, in mice, MitoQ can reduce oxidative stress in the mitochondria. The main question that this clinical trial aims to answer is: • Does MitoQ supplementation, compared to placebo, improve cognition in HR patients? Secondary questions that this clinical trial aims to answer are the following: Does MitoQ supplementation, compared to placebo: - Improve positive and negative symptoms of SSD in HR patients? - Improve functioning in HR patients? - Improve/normalize blood markers of mitochondrial dysfunction in HR patients? The investigators will enroll 100 individuals with E-SSD. These enrolled participants will participate in an initial screening visit to determine if they qualify for the actual clinical trial. At the screening visit, the investigators will ask about psychiatric history to determine diagnosis; ask about medical history; do a physical exam; collect blood and urine samples; do a pregnancy test; and ask participants to bring in their current medications in their original packaging so it is known what they are taking. After the screening visit, the investigators will invite 50 HR patients (identified with a blood test) to continue with the clinical trial. Participants who qualify for the clinical trial will be asked to: - Take a supplement (MitoQ or placebo) once per day for 12 weeks in addition to their usual medications. - Come in for a study visit every 4 weeks over the 16-week study period. At these study visits, the investigators will do a physical exam; ask about symptoms and side effects; take blood and urine samples; and ask questions about general health and well-being, quality of life, mental health, emotional health, and mood. At visits 1 (baseline) and 4 (12 weeks), participants will also take a cognitive assessment.
This study will investigate whether a single dose of diazepam (5mg) compared to placebo can modulate brain chemistry (GABA/glutamate levels) and function (blood flow, neural response and connectivity during tasks and at-rest) in 24 individuals at clinical high-risk for psychosis.
In its 2012's release guideline on therapy for schizophrenia, the EMA joined the FDA to acknowledge primary and persistent negative symptoms (PNS) as an unmet need in the treatment of schizophrenia. Functional brain imaging studies showed a correlation between NS and reduced perfusion in the left dorsolateral prefrontal cortex (L-DLPFC). Pre-frontal activation (PFA) using repetitive transcranial magnetic stimulation (rTMS) significantly improve PNS (meta-analyses: effect size SMD = 0.55, ΔPANSS-N = -2.5). Yet schizophrenia is likely to gather many different natural entities of distinct pathophysiological mechanisms. Pursuing a one-size-fits-all approach will not adapt to this diversity and might account for inconsistencies in the results. Progressive periodic catatonia (PPC) is a rare psychotic phenotype (0.1 - 0.5 ‰) which has been shown to be longitudinally stable (30-years follow-up) and consistent within families (about 1 third of first-degree relatives are affected). The core of this phenotype is a disintegration of psychomotor processes which progresses with each relapse, resulting in a "deficit state", i.e., PNS, responsible for most social and occupational disabilities. The investigators and others reported PPC to come with hyper-perfusions in premotor cortices compared to controls or non-PPC chronic psychoses (nPPC). These hyper-perfusions discriminate PPC from nPPC or depressive patients (Sensitivity = 82%; Specificity = 95%). Last, in independent proof-of-principle studies the investigators and others have shown that premotor inhibition (PMI) using rTMS significantly improved PNS in PPC and that the most dramatic improvements followed personalized accelerated rTMS protocols (5 days of rTMS; CGI-improvement = 2 which is equivalent to ΔPANSS-N = -10; lasting > 1 month - vs virtually no change for PFA). The efficacy index was very good (no side effects). the investigators hypothesize that: (1) in PPC, add-on personalized premotor inhibition (PMI) is more effective in reducing PNS than L-DLPFC activation (PFA); (2) patient stratification is relevant as personalized PMI will not be as effective in the nPPC group (even expected to be less effective than PFA).
This study presents the development and validation of a unique Digital Experience Sampling Method (ESM) questionnaire specifically adapted for monitoring changes in the mental state of patients during psychiatric hospitalization. The questionnaire was carefully crafted through focus groups involving patients and clinical staff, ensuring its relevance and applicability to the unique characteristics of mental state changes in a hospitalization setting. To evaluate the validity of the ESM questionnaire, symptom severity trends obtained from the questionnaire will be compared with estimates derived from the Positive and Negative Syndrome Scale (PANSS) assessment. Data will be collected from 100 subjects over a 14-day psychiatric hospitalization period. In addition to the ESM questionnaire, smartwatch sensors will monitor physiological indicators. Feasibility and patient compliance will be assessed by examining patients' willingness to use the digital ESM questionnaires and the smartwatch sensors. The study will also cross-reference self-reported sleep quality and activity levels captured in the ESM questionnaires with objective physiological indicators and nursing staff reports, providing insights into the reliability of the patient-reported data. Furthermore, the study will evaluate the impact of the ESM data on clinical decision-making by physicians throughout the 14-day psychiatric hospitalization period. Patient satisfaction and satisfaction among the multidisciplinary team with the monitoring model will also be assessed. This research underscores the potential of digital technologies to enhance patient-centered care and facilitate informed treatment decisions in psychiatric hospitalization settings.
This is a Phase 2, randomized, double-blind, placebo-controlled, multi-center inpatient study to evaluate the efficacy and safety of LB-102 in adult patients diagnosed with acutely exacerbated schizophrenia. To determine whether LB-102 administered to patients with acutely exacerbated schizophrenia demonstrates antipsychotic efficacy, as determined by a change from Baseline on the Positive and Negative Syndrome Scale (PANSS) total score, compared to placebo at 28 days. The secondary objectives of the study are to evaluate improvement in CGI-S, safety and tolerability, and pharmacokinetics.
Evaluation effectiveness and safety of TMS in subjects with catatonia
This study explores the potential of an interactive narrative game to enhance medication adherence among stable schizophrenia patients. Employing participatory design methods, game's development and testing process actively involved patients and individuals closely connected to their daily lives. Artificial Intelligence-Generated Content (AIGC) facilitated swift iterations in game's visual style and content. During game therapy, patients are tasked with making decisions based on presented situations, which influence the course of the narrative.
