Schizophrenia is a severe and persistent psychological disorder affecting 0.7 to 1% of the world's population and 600,000 people in France. Schizophrenic patients are exposed to excess mortality and a life expectancy that is 10 to 15 years lower than the general population (excluding causes of suicide) and to numerous co-morbidities, including oral diseases. To improve this public health problem, concrete action must be undertaken and evaluated in both quantitative and qualitative terms. While there are many quantitative indicators, there are no reliable and valid tools for the perceived oral health of these individuals in the context of their real and/or imagined world. The results of a qualitative study previously carried out by our team (QUALITY Study: NCT02730832) made it possible to develop two hypothetical questionnaires for evaluating quality of life related to oral health, the Schizophrenia Oral Health Profile (SOHP), and a questionnaire for evaluating coping strategies with regard to oral health, the Schizophrenia Coping Oral Health Profile (SCOOHP). However, before these questionnaires can be used in clinical practice, their psychometric properties must be validated.
This is a Phase 2, randomized, double-blinded, placebo-controlled, inpatient study to examine the efficacy, safety, and tolerability profile of KarXT in adult subjects diagnosed with DSM-5 schizophrenia who are in an acute exacerbation phase. The primary objective of the study is to assess the efficacy of KarXT (a fixed combination of xanomeline and trospium chloride) (xanomeline 125 mg/trospium 30 mg twice daily [BID]) versus placebo in reducing Positive and Negative Syndrome Scale (PANSS) total scores in adult inpatients with a Diagnostic and Statistical Manual-Fifth Edition (DSM-5) diagnosis of schizophrenia. The secondary objectives of the study are to assess overall safety and tolerability of KarXT in adult inpatients with a DSM-5 diagnosis of schizophrenia.
Cognitive Remediation (CR) involving restorative and strategy-based methods has been previously validated in a pilot study for late life schizophrenia (LLS), where CR demonstrated a moderate effect on overall cognition. This study proposes to study the efficacy of CR in a larger cohort of participants with LLS and to assess the interaction of medication management with CR on cognitive outcomes. Eligible participants will receive CR during 12 weeks. CR consists of a series of computerized exercises targeting various cognitive functions, such as memory, attention and processing speed. It will be administered during facilitated group sessions consisting of 4-6 people. The study will recruit 40 participants with the aim to enroll 30 LLS participants age 55 or older who will undergo the CR intervention for two, 2-hour weekly classes over 12 weeks (24 classes in total). There will be baseline assessments (clinical and NP) prior to enrollment in the classes. In order to assess whether there has been a change in cognition, and some of the assessments will be repeated after the 12-week intervention.
This is a prospective, observational, naturalistic study conducted according to Italian law. The Investigators are interested in observing how often Evidence Based (EB) psychosocial and rehabilitative interventions are actually offered to patients in the real world clinical practice of psychiatric Italian services able to deliver this kind of treatments, focusing on a cohort of patients with recent onset schizophrenia, for whom delivery of integrated treatments is especially recommended, treated continuously with Long Acting Injection (LAI) antipsychotics. The primary objective of this study is to explore the level of implementation of EB psychosocial/rehabilitative treatments during a prospective 12-month period in patients with recent onset schizophrenia (≤ 5 years) being treated with a LAI Antipsychotic in Psychiatric Departments with expertise in the application of such interventions and to describe the reasons of implementing the particular EB psychosocial intervention and the clinical-functional characteristics of patients assigned to them. The prospective design is strictly required both for allowing consistent definition and application of such interventions and for describing reliably the characteristics of patients assigned to them. Secondary objectives are to describe the reasons for the choice of the specific assigned psychosocial intervention (if any) and the clinical and functional treatment outcomes of patients assigned or not-assigned to EB psychosocial therapies.The assignment of a patient to any particular treatment is not decided in advance by the study protocol, but falls within current clinical practice. Inclusion criteria are: - Patients with schizophrenia (F20 according to ICD-10 version 2013) - Onset of schizophrenia, defined as the first onset of symptoms that required specific antipsychotic treatment or hospitalization, as derived from anamnesis or available clinical documentation, not more than 5 years before study entry - Age between 18 and 40 years - Patients under treatment with a LAI on the basis of physician's decision (LAI started no longer than 6 months before study entry) and clinically stable (no relapse requiring hospitalization or change of treatment due to clinical worsening) during the last 1 month. Primary outcome of interest ("endpoint") is percentage of patients within the total study population who have been assigned to any EB psychosocial/rehabilitative treatment (listed below) for at least 1 month consecutively during the 12-month observation period (given the heterogeneity of interventions, this is an arbitrary duration which may reliably indicate a significant exposure to a given intervention). The percentage of each type of psychosocial intervention delivered together with frequency of sessions and length of treatment, and the reasons (categorized) given by the clinicians to justify the selected psychosocial intervention as well as the clinical-functional characteristics of patients assigned to them will be described. Patient assignment to the different interventions and their delivery will be traced in the patients' clinical charts. A list of key-words to describe each intervention will be provided in order to identify reliably and univocally the activities delivered. Secondary endpoints: - Sociodemographic information - Percentage of patients assigned during the 12-months period to at least one non EB intervention for at least 1 month consecutively (given the heterogeneity of interventions, this is an arbitrary duration which may reliably indicate a significant exposure to a given intervention) but not to any of the EB interventions. - Percentage of relapses - % of patients who discontinue drug treatment (for ineffectiveness, side effects or other reasons and patient/physician decision) and/or psychosocial interventions (for team or patient decision) - Changes in clinical, cognitive, functional and quality of life measures Additional endpoints: - Health economic information collected through 3 specific questionnaires: detection of i) health resources consumption for the care of the disorder (direct costs, eg. drug cost, hospitalization, emergency visits, Day hospitals, General Physician visits…) and assessment of indirect costs through evaluation of : ii) patient's potential income loss, absenteeism and presenteeism to estimate work productivity, daily activity impairment due to the mental illness and of iii) caregiver's potential income loss, commitment of time for the patient's care, absenteeism and presenteeism to estimate work productivity, daily activity impairment because of the patient's mental illness
The study is aimed to assess the severities of hyperprolactinemia caused by antipsychotic drugs and the effects of the duration of hyperprolactinemia on bone metabolism in schizophrenia patients.
This 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.
A single-centered randomized controlled trial with a parallel-groups design is utilized, comprised of mindfulness-based group therapy (MBGT) in the experimental condition, and treatment as usual (TAU) in the control condition. Participants in the experimental condition continued their regular psychiatric treatment (TAU) next to the participation in the MBGT. In order to evaluate possible psychotherapeutic effects, self-report and other clinical questionnaires including interviews and app-based assessments are evaluated before (T0), and after the four-week intervention (T1). Ward psychiatrists identify eligible participants and invite them to participate in the study. An eligibility screening is held by the study assistant at baseline, introducing the study, providing informed consent in written form, as well as conducting the self-report measures and app-based assessments. A blinded psychiatrist who works independently of the (co-) therapist conducts the remaining rater-questionnaires. Due to the psychotherapeutic nature of the study, information about the treatment allocation had to be shared with the co-therapist and the participants. Randomization was conducted by the Random Group Generator (pubmed, 2018). The data management plan includes standard procedures for data-handling such as using anonymized identification codes for patient data. The participants have the right to access their data, and the right to claim an annihilation. The data is being stored in locked cupboards, only allowing researchers involved in the study to access the data.
This study investigates the effects of RO6889450 on the negative symptoms associated with schizophrenia and schizoaffective disorder.
This is a phase 1, double-blind, placebo-controlled, 3 period cross-over study to evaluate CVN058 target engagement by measuring auditory evoked potential mismatch negativity (MMN) downstream to 5-hydroxytryptamine receptor 3 (5-HT3) as a pharmacodynamic (PD) marker.
