Filter by:Primary Objective: Efficacy of Occupational Therapy (OT) based Occupational Goal Intervention (OGI) in improving executive functions in patients with refractory schizophrenia as measured by the BADS. Secondary Objectives: improvement of functional aspects,basic and instrumental activities of daily living,negative symptoms and cognitive functions improvement Hypothesis: OT is more effective than control group to improve executive functions in patients with refractory schizophrenia.
The purpose of this observational multicenter-study is to investigate safety of psychopharmacological treatment and rates of adverse drug reactions in gerontopsychiatric inpatients. Elderly people are at higher risk for developing side effects under pharmacological treatment due to an altered metabolic situation, higher comorbidity rates and often polypharmacy. Furthermore gerontopsychiatric patients can often not articulate their symptoms clearly, for example due to pronounced cognitive impairment. The aim of the study is to gain valid data of possible adverse drug reaction rates, their potential risk factors and outcome, as well as medical prescription practises. To assess these outcomes an intensive pharmacovigilance-monitoring will be conducted at the five participating study sites. At Baseline demographic data, previous and present disorders, use of drugs, previous and present medication, quality of life, cognitive function, physical examination results, laboratory results and ECG will be assessed. Afterwards patients are visited weekly and screened for possible adverse drug reactions. All adverse drug reactions will be coded in the MedDRA-system. In case of a possible serious adverse drug reaction serum levels of all psychotropic substances applicated will be assessed. Drug combinations will be analysed using an established advanced bioinformatic tool (mediQ). Diagnosis, medication intake and possible adverse drug reactions are documented continually. 2 weeks after discharge from the ward, patients will be contacted by phone to assess catamnestic data.
The purpose of this study is to determine effect of Fluvoxamine augmentation on cognitive function , aggressive behavior , clinical symptoms and mRNA (messenger ribonucleic acid) and protein expression in human peripheral mononuclear blood cells (PMC) in medicated schizophrenia patients
The aim of the present study is to assess the availability of cannabinoid receptors (CB1R) in the human brain. CB1R are present in everyone's brain, regardless of whether or not someone has used cannabis. The investigators will image brain cannabinoid receptors using Positron Emission Tomography (PET) imaging and the radioligand OMAR, in healthy individuals and several conditions including 1) cannabis use disorders, 2) psychotic disorders, 3) prodrome of psychotic illness and 4) individuals with a family history of alcoholism, 5) Post-Traumatic Stress Disorder 6) Opioid Use Disorder using the PET imaging agent or radiotracer, [11C]OMAR. This will allow us to characterize the number and distribution of CB1R in these conditions. It is likely that the list of conditions will be expanded after the collection of pilot data and as new data on cannabinoids receptor function and psychiatric disorders becomes available. Those in the cannabis us disorder arm of the study will have a PET scan on at least three occasions: once while smoking as usual, once after 48-hours of abstinence from cannabis, and a final time after 4 weeks of abstinence. Additional scans may be conducted within the 4 weeks and the last scan may be conducted well beyond 4 weeks. Similarly, while most schizophrenia patients may get scanned just once, a subgroup of patients may get scanned more than once. For example to tease out the effects of medications, unmedicated patients may get scanned while unmedicated and again after treatment with antipsychotic medications. Similarly prodromes may get scanned while in the prodromal stage off medications, on medications and after conversion to schizophrenia.
Schizophrenia is a chronic debilitating mental disorder, characterised by a relapsing remitting course. Although anti-psychotics can prevent relapse, its effect on schizophrenia outcome remains very limited, mainly due to very poor adherence to medications by the patients. This study aims to find, whether the add-on of remote monitoring of medication compliance via tele-medicine, to routine out-patient clinic care, can improve patients adherence and reduce the risk of relapse.
Apathy, defined as a quantitative reduction of voluntary, goal-directed behaviours (GDB), is a core component of negative symptoms. It has been suggested that the physiopathology of apathy is not a single entity but may be multiple, depending on which specific process or macrofunction is disrupted during completion of GDB. In line with this notion, Levy and Dubois proposed dividing apathic syndromes into three subtypes of disrupted processing: 'a-motivation', 'cognitive inertia', and 'uncoupling'. In schizophrenia, apathy has been associated with executive dysfunction, functional impairment and poor outcome. However, the neurobiological underpinnings of apathy in schizophrenia are poorly understood. Primary objective: confirm that chronic schizophrenic patients are apathic compared to healthy volunteers Secondary objectives: - investigate if apathy is related to a particular aspect of the disease (i.e. negative, positive symptomatology and/or deficit form) - investigate if apathy correlates with executive dysfunction - investigate if apathy is associated with a specific mechanism using an experimental task specially designed to investigate the different mechanism (i.e. 'a-motivation', 'cognitive inertia', and 'uncoupling') - investigate if there is a volumetric abnormality affecting the executive system in apathic schizophrenic patients - link these eventual volumetric abnormalities to prefrontal cortex-basal ganglia circuits according to a specific subtype of apathy in the apathic schizophrenic group
The aim of this study is to explore the levels of internalized stigma in a sample of young patients with bipolar disorder or schizophrenia.
The investigators will test the hypothesis that the sleep medication, eszopiclone, can normalize brain activity during sleep and improve memory in patients with schizophrenia. The investigators will do this by comparing sleep and performance in participants taking eszopiclone to participants taking placebo. The investigators will study healthy subjects and patients with schizophrenia taking atypical antipsychotic medications.
This study aims to examine the efficacy of minocycline augmentation in a sample of moderately ill outpatients with early-course schizophrenia on their chlorpromazine-equivalent doses of second-generation antipsychotic medications. The investigators hypothesize that as compared to placebo a 2-month treatment with minocycline in 120 volunteers with early-course schizophrenia will result in a more significant improvement in psychopathology (primary outcome) and cognitive symptoms (secondary outcome). In addition, cytokine plasma levels will be used as another secondary outcome measure to see if treatment-induced changes in total PANSS score are associated with changes in cytokine levels.
The purpose of the study is to investigate the effect of a 30 hour cognitive remediation program for young patients with early phase schizophrenia spectrum disorders on cognitive, clinical and functional outcome measures. The remediation program is integrated with whatever active rehabilitation the participant is currently attending (school, work, day program etc).
