Filter by:People with schizophrenia tend to have problems with attention and concentration. Studies found that these patients are unable to block or gate out non-relevant and distracting information (e.g., noises). This may lead to brain overload. Cognitive abilities like concentration, memory, and learning may worsen. This ability to filter sensory information has been linked to a gene that affects the way nicotine acts in the brain. Patients with schizophrenia have a high rate of cigarette smoking. 60% to 90% smoke compared with 25% of the general population. It has been suggested that these patients may use nicotine to improve their ability to block out distracting information. Brain wave activity (EEG) in response to sounds has been proved useful in understanding this gating problem. The present study uses EEG measures and performance tasks to find out what a new nicotine-like treatment, which will be added to ongoing treatment medications, does to gating and cognition. It is hoped that this new treatment will improve the way in which patients process information, as this may help them in day-to-day activities.
Efficacy and safety of Tandospirone combined with Atypical Antipsychotic drugs to Improve Cognitive function in Schizophrenia
It is well established in studies across several countries that tobacco smoking is more prevalent among schizophrenic patients than the general population. Electronic cigarettes (e-cigarettes) are becoming increasingly popular with smokers worldwide. To date there are no large randomised trials of e-cigarettes in schizophrenic smokers. A well-designed trial is needed to compare efficacy and safety of these products in this special population.
Jockey Club Early Psychosis (JCEP) project is a territory-wide specialized EI service that is launched in August 2009 and provides 3-year phase-specific intervention for adult patients presenting with first-episode psychosis (FEP) to psychiatric units of Hospital Authority (HA). To promote early functional recovery, JCEP project develops recovery-oriented intervention based on life coaching approach (recovery-oriented coaching) in addition to case management. This is a structured group-based coaching program incorporating cognitive-behavioural and solution-focused therapeutic components. The program facilitates patients to undergo active change process via identification of achievable goals, formulation of action plans, provision of feedback and progress monitoring for goal attainment. Subjects will be randomized (block size: 2) to receive either recovery-oriented coaching program (intervention group) or supportive therapy (control group). Intervention group Subjects are scheduled to receive a 6-month group-based recovery-oriented coaching program. This is a structured, manualised treatment program based on life coaching principles with cognitive-behavioural and solution-focused elements incorporated. It guides subjects to undergo an active, yet stepwise change process by stimulating motivation, setting achievable goals, generation of action plans via collaborative exploration, fostering self-regulatory capacity, and provision of autonomy-supportive treatment environment and peer support. Subjects' perceived competence, sense of control, self-management skills and hence functioning will be improved via successful experiences and positive feelings generated after attainment of self-initiated goals. Cognitive-behavioural techniques such as self-monitoring, activity scheduling and behavioural modification will be employed. Control group Subjects will receive group-based supportive therapy provided by case managers of JCEP project. The therapy provides patients with psychoeducation about psychosis, stress management, emotional and social support. Coaching and cognitive-behavioural techniques will not be incorporated. Therapy sessions and duration will be comparable to that of recovery-oriented coaching program. Assessments Each subject will be assessed at three time points, i.e., baseline before randomization (T1), 12 weeks (T2, post-phase I intervention) and 24 weeks (T3, post-phase II intervention). Assessments on symptomatology, functioning and subjective wellbeing will be administered at all time points. Cognitive and reinforcement learning assessments will be conducted at T1 and T3. functional magnetic resonance imaging (fMRI) will be performed at T1 and T3 for the first 20 subjects recruited in each treatment group. A group of healthy volunteers matched in sex, age and educational level will be recruited from the community with fMRI, cognitive and reinforcement learning evaluations done at T1 and T3. To maintain blinding to treatment assignment, assessments will be conducted by research assistants who are independent of treatment delivery and randomization. Subjects will be trained to not reveal their treatment allocation before each follow-up assessment.
The research aims to investigate the relationship between self-control ability and blood glucose level in schizophrenic patients. The main purpose of the present study is to explore whether the close relationship of blood glucose and self-regulatory strength observed in healthy individuals, is applicable to schizophrenic patients. More specifically, the current study aims - to investigate whether the exertion of self-control reduces blood glucose, - to examine whether low level of blood glucose deteriorates subsequent self-control performances - to examine whether restoring the glucose level eliminates these impairments, in schizophrenic patients.
The aim of this study is to examine the prevalence of the Metabolic syndrome(MetS) in Korean patients with schizophrenia. Primary objective: • To investigate the prevalence of the MetS in Korean patients with schizophrenia Secondary objectives: • To compare the prevalence of the MetS among 3 groups according to antipsychotics: typical antipsychotic monotherapy group, atypical antipsychotic monotherapy group, 2 or more antipsychotics group (polypharmacy)
The purpose of this study is to compare efficacy and safety of add-on treatment with a moderately high dose of D-serine, an NMDA-glycine site agonist, in young, recent onset schizophrenia patients who suffer from significant symptoms despite treatment with antipsychotics.
This study will determine the effects on brain myelination and cognition of oral risperidone (Risperdal) versus long-acting injectable paliperidone palmitate (Invega Sustenna) in first-episode schizophrenia subjects. The hypothesis being tested is that continual inhibition of enzymes such as glycogen synthetase kinase 3 provided by injectable paliperidone palmitate will promote myelination to a greater extent than oral risperidone.
The ability to understand the other's perspective and respond accordingly is the most important normal process of daily social life and is probably one of the foundations of human existence. This capability is reflected, inter alia, as an imitation - an important and effective form of learning which is very developed in humans. When we are required to imitate a particular movement, speed of response depends on the perspective of the movement. Imitative response is implemented faster when the movement is observed from first-person perspective, than if the motion is presented from the perspective of a third party. While healthy individuals don't find it difficult to imitate, or to understand the other's emotion expression, there are psychiatric populations (such as autism and schizophrenia) who find it difficult to demonstrate these capabilities (Park, Matthews et al. 2008). Beyond these capabilities impairment, schizophrenic patients have difficulty distinguishing between their arm movements and those of a foreign hand and find it difficult to leave the boundaries of egocentric interpretation of reality and adopt the other's point of view. These behavioral disorders arise from defects in the network of mirror neurons (Buccino and Amore 2008; Langdon, Coltheart et al. 2010). Therefore, the investigator expect that schizophrenic patients will not see a preference for movements that will be displayed in first-person perspective from the same movements that will be displayed from the perspective of a third party. Consequently, the investigator speculate that these subjects will not exhibit differences at imitating the response of which will be presented from different perspectives (Jackson, Meltzoff et (al. 2006.
The objective of the study is to evaluate the efficacy of Pramipexole, Minocycline and Aspirin compared to placebo, as add-on to anti-psychotics in the treatment of patients with schizophrenia.
