Filter by:Brief Summary: In schizophrenia, dislocation of psychic functions involving a loss of contact with reality is frequently found. A fragmentation of motor and sensory perceptions could be held responsible. However, automatic integration between perception and action is the necessary condition to be in "relationship with the world." Affordance is the experimental link between object perception and potentially associated actions (Gibson, 1977, 1979) explored by Stimulus Response Compatibility (SRC) paradigm. With Tucker & Ellis sensory motor compatibility task (1998), with a modified response device (responses given with grasp), we study the impact of motor activation on these affordance effects. In this study, a group of controls will also be included in order to understand, as precisely as possible, the mechanisms involved (i.e., interference between the perception of the object and the response gesture).
In schizophrenia, dislocation of psychic functions involving a loss of contact with reality is frequently found. A fragmentation of motor and sensory perceptions could be held responsible (Fuchs, 2005). However, automatic integration between perception and action is the necessary condition to be in "relationship with the world." Affordance is the experimental link between object perception and actions potentially associated (Gibson (1977, 1979) explored by Stimulus Response Compatibility (SRC) paradigm. The existence of visual motor neurons leads us to postulate that the affordance effect can be assisted by a visuomotor priming of a hand in a position to grasp. With Tucker & Ellis sensory motor compatibility task, we study the capacity of affordance in schizophrenia, as well as the impact of perceptual motor priming on these affordance effects.
Auditory hallucinations are common (present in 60-70% of cases) and extremely debilitating. Behavioral disorders associated with them can have serious social repercussions. However, in 25% of cases the usual antipsychotic drug treatments are incompletely or totally ineffective. Fifteen subjects will be included after collection and signed their informed consent. The rTMS treatment is made of 4 sessions of 13 minutes spread over two days, at a frequency of 20 Hz and an intensity of 80% of motor threshold at rest. These constants are used to stay below the risk of occurrence of seizures, the only serious side effects identified. Furthermore the rTMS treatment is almost painless: tension headaches are the main side effects and make amends with simple analgesics. rTMS is devoid of neurocognitive effects. The LEFT stimulation site will be established through a anatomofunctional imaging before treatment (between D-7 and D0). Treatment efficacy will be evaluated daily during treatment (days 1 and 2) and during the first 2 weeks of starting treatment.
The aim is to evaluate the effectiveness of an intervention based on a program of physical activity and diet coordinated between primary care teams (PCT) and Mental Health Centres (MHC) to modify the weekly physical activity (PA) amount, body mass index (BMI) and waist circumference in patients with severe mental disorder diagnoses. To assess changes in cardiovascular risk, quality of life and lifestyles, secondarily. Methods: A randomized clinical trial with a control group, of one year of follow-up, carried out in four MHC Barcelona and Santa Coloma, and PCT of reference. The investigators studied patients aged 18 - 65 years old, diagnosed with schizophrenia, schizoaffective or bipolar disorder, with antipsychotic medication and a low level of PA. 240 patients will be selected in each group (difference to be detected in the BMI:> 1.89 kg/m2; common SD: 6.2, 30% loss). Intervention: group educational PA program (basically walking) of 24 sessions over 12 weeks, and diet (8 sessions in the first 8 weeks) by nurses and specialists in PA. Key measurements: level of PA (IPAQ questionnaire), physical examinations: BMI, waist circumference, blood pressure, cardiovascular risk, quality of life (SF-36), smoking habits, dietary habits (PREDIMED questionnaire), analytical parameters: cholesterol , triglycerides, blood glucose. Evaluations will be masked and conducted at 0, 3, 6 and 12 months. Analysis of variance for repeated measures to adjust for differences attributable to the effect of the intervention for potential confounders: pharmacological treatment, care level of intervention and mental state.
This study determined if a single dose of LY2140023 (pomaglumetad methionil) affects the electrical activity in the heart in participants with schizophrenia. This study also helped determine how a single high dose of LY2140023 is tolerated by participants.
augmentation of clozapine with paliperidone in the treatment of resistant schizophrenia has not been tested until now in randomized controlled trials. This combination is supposed to have therapeutic efficacy in the treatment of resistant schizophrenia.
Adjuvant N-methyl-D-aspartic acid (NMDA)-enhancing agents, such as GlyT-1 inhibitors and NMDA-glycine site agonists have been demonstrated to be beneficial for chronic schizophrenia patients. The purpose of this study is to evaluate efficacy and safety of add-on treatment of an inhibitor of D-amino acid oxidase (DAAOI), DAAOI-1, in chronically stable schizophrenia patients who have been stabilized with antipsychotics.
The trial is designed to assess the long term subjective well-being in schizophrenic outpatients treated with quetiapine XR (extended release) or oral risperidone at flexible dose in a naturalistic setting over a period of one year. Secondary outcome measures have been selected for helping in the differentiation of the compared atypical antipsychotics. The primary objective of this study is to demonstrate the non-inferiority of quetiapine XR to risperidone assessed at month 6 in terms of responder rate using the self-report instrument SWN-K
The primary aim of the project is to examine the efficacy of the Psychiatric Rehabilitation Weight Loss program in reduction of weight and body mass index (BMI.
Both GlyT-1 inhibitors and NMDA-glycine site agonists have been demonstrated to be beneficial for chronic schizophrenia patients. The purpose of this study is to compare efficacy and safety of add-on treatment of sarcosine, a GlyT-1 inhibitor, and D-serine, an NMDA-glycine site agonist, in chronically stable schizophrenia patients who have been stabilized with antipsychotics.
