The purpose of the study is to examine the effects of cognitive training on emotion regulation, impulse control, and aggression in people with schizophrenia. The study compares a combination of computerized cognitive remediation and social cognition training (CRT+SCT) to cognitive remediation alone (CRT). Study outcomes include multiple measures of aggression, emotion regulation, impulse control, cognition, and symptoms.
Cognitive impairment is a core symptom of schizophrenia and is in a large part responsible for the poor psychosocial outcome of the disorder. The use of non-invasive brain stimulation techniques as a therapeutic option is just commencing for neuropsychiatric patients. Concerning healthy subjects the investigators have previously shown that anodal tDCS to the right dorsolateral prefrontal cortex (DLPFC) parallel to working memory training can sustainingly enhance performance in a spatial n-back task. Additionally, first translational experiments regarding the use of anodal tDCS to improve working memory (WM) in patients with schizophrenia rendered promising results. On those grounds, the investigators now test the hypothesis that anodal tDCS to the right DLPFC can augment working memory training in patients with schizophrenia.
The primary purpose of this study is to test the effects of a targeted, computerized cognitive training program on verbal memory in older women who have undergone chemotherapy treatment for early-stage breast cancer. As measured by neuropsychological assessment, this treatment will result in improved verbal memory. Secondarily, processing speed and naming abilities are expected to improve. Enhanced self-perception of cognitive ability is also expected.
Cognitive biases are a hallmark of depression but there is scarce research on whether these biases can be directly modified by using specific cognitive training techniques. The aim of this study will be targeting and modifying specifically relevant attention biases in participants with subclinical depression using eye-tracking methodologies. This innovative approach has been proposed as a promising future line of intervention in Attention Bias Modification procedures (Koster & Hoorelbeke, 2015). Recent findings suggest that depression is characterized by a double attentional bias (Duque & Vazquez, 2015), More specifically, depressed individuals have difficulties both to disengage from negative materials (e.g., sad faces) and to engage with positive materials (e.g., happy faces). Thus, training procedures to change attentional biases should target these two separate components.
Cognitive rehabilitation is defined as a systematic functionally oriented intervention of therapeutic cognitive activities based on the assessment and understanding of patient's brain behavior deficits. This project focuses on restoring cognitive functions in order to understand the underlying deficits in the patient's brain by developing integrated cognitive rehabilitation scenarios in virtual reality that combine memory, attention and problem solving training with context specific motor movements.

The purpose of this study is to attempt to treat cognitive and negative symptoms of schizophrenia, with the nutritional supplement N-acetylcysteine (NAC). Schizophrenia is a chronic mental disorder that affects approximately 65 million people worldwide, and causes significant disability and suffering. Patients with schizophrenia often hear voices and have persecutory delusions. Though these are the most recognizable features of the illness, the deficits most closely linked to disability are known as cognitive deficits and negative symptoms. Cognitive abilities refer to the ability to perform mental tasks that require focus and attention, and also include memory and verbal skills. Negative symptoms refer to a lack of interest in the world, and decreased social interactions. In our study, the investigators aim to improve these symptoms and deficits by targeting the glutamate system. Glutamate is the major excitatory neurotransmitter in the brain, and its regulation is abnormal in schizophrenia: glutamate levels are too low at some receptors, and too high at others. As well, free radicals surrounding glutamate receptors also interfere with their proper function. N-acetylcystine (NAC) is a safe and widely-available dietary supplement that may restore glutamate to its correct levels in the brain, and may also help protect the brain from antioxidant damage. In our study, patients with schizophrenia will be randomly assigned to receive either NAC or placebo for 8 weeks. Brain levels of glutamate and an important antioxidant, glutathione, will be measured before and after treatment, using a neuroimaging technique known as magnetic resonance spectroscopy. Cognitive and negative symptoms will also be assessed before, during and after treatment. The investigators hypothesize that glutamate and glutathione will be normalized in patients' brains, and that their negative and cognitive symptoms will be improved, too.
The purpose of this study is to evaluate the early and late effects of Transcranial Led Therapy (TLTC) in memory and executive functions in patients with moderate and severe TBI history (TBI time longer than 3 months).
This clinical trial tests the feasibility, effectiveness and patient satisfaction with cognitive remediation therapy for patients diagnosed with schizophrenia or schizoaffective disorder within a forensic hospital. It is hypothesised that patients receiving cognitive remediation therapy will have an improvement in cognitive performance, real world functioning, symptoms, violence risk and benefit more from additional psychosocial treatment programmes over time relative to patients receiving treatment as usual. Furthermore it is hypothesised that it will be feasible to carry out such a study and that patients will report high rates of satisfaction with cognitive remediation therapy. Finally it is hypothesised that differences on the effectiveness measures will be maintained at 6 month follow up after the end of treatment.
