Investigating the Cognitive Source of Visual Working Memory Impairment in Schizophrenia
Memory Deficits Schizophrenia Neurostimulator; ComplicationsThe investigators plan to investigate the effect of enhancement on visual working memory (VWM) in patients of chronic schizophrenia and determine the predictive factors of effective treatment.
Remote State Representation in Early Psychosis
PsychosisSchizophrenia9 moreThe purpose of this study is to examine state representation in individuals aged 15-40 who have been diagnosed with a psychotic illness, as well as young adults who do not have a psychiatric diagnosis. State Representation is our ability to process information about our surroundings. The investigators will complete some observational tests as well as a cognitive training clinical trial.

Study to Assess Adverse Events and Change in Disease Activity of Oral Cariprazine Capsules in Adult...
SchizophreniaSchizophrenia is a common and severe psychiatric illness characterized by extreme disturbances of cognition and thought, affecting language, perception and sense of self. This study will assess how safe and effective cariprazine is in treating adult participants with schizophrenia in Japan and Taiwan. Adverse events and change in disease activity will be assessed. Cariprazine (VRAYLAR) is an approved drug for the treatment of schizophrenia in the United States. In the first 6-week period, participants are placed in 1 of 2 groups, called treatment arms. Each group receives a different treatment. There is a 1 in 2 chance that participants will be assigned to placebo. In the next 18-week period, participants will have the option to receive 1 of 3 doses of cariprazine. Approximately 250 adult participants, 18-65 years of age with schizophrenia will be enrolled in approximately 55 sites across Taiwan and Japan. Participants will receive oral capsules of cariprazine or placebo for 6 weeks. Upon completion of 6-week treatment period, participants will be eligible to receive oral capsules of cariprazine for additional 18 weeks. The safety follow up period will follow after for an additional 8 weeks. There may be higher treatment burden for participants in this trial compared to their standard of care. Participants will attend regular visits during the study at a hospital or clinic. The effect of the treatment will be checked by medical assessments, blood tests, checking for side effects and completing questionnaires.

tDCS and Executive Function Training for Schizophrenia
SchizophreniaSchizophrenia Spectrum Disorder1 moreSchizophrenia-spectrum disorders are the most persistent, debilitating, and economically burdensome mental illnesses worldwide. Cognitive remediation (CR) is a psychological intervention based on principles of learning and neuroplasticity to improve cognitive abilities. The investigators previously developed a novel CR intervention specifically targeting executive functions and aimed here to enhance its effect on functioning by combining it with Transcranial direct current stimulation (tDCs). The primary goal is to determine whether receiving tDCS prior to CR improves one's ability to engage in cognitive activities and enhance cognitive abilities. To do so, 40 participants will be recruited with schizophrenia-spectrum disorders from Ontario Shores inpatient units, half of whom will receive real tDCS and half will receive sham tDCS, whereas all will receive CR. This study will provide important information on whether the outcome of training executive function can be further enhanced with non-invasive brain stimulation.

Adjunctive Methylphenidate ER in Patients With Schizophrenia to Improve Functional and Cognitive...
Schizophrenia SchizoaffectiveTwo of the major features of schizophrenia spectrum illness, negative and cognitive symptoms, have been associated with poor functional outcome and burden of illness. Given the proposed role of dopaminergic hypoactivity, augmentation with psychostimulants has been postulated as one of the potential treatment options for negative and/or cognitive symptoms of schizophrenia. The major drawback for use of these agents is a potential risk of relapse or worsening of psychosis through direct or indirect dopamine agonism activity and a great deal of caution has been called for use of stimulants in individuals with psychosis. However, preliminary results of earlier studies indicated improvement of negative and cognitive symptoms with off-label use of adjunctive psychostimulants. The present study aims to assess off-label use of adjunct psychostimulants in patients with schizophrenia in a tertiary mental health centre, focusing on efficacy and safety.
