6 Clinical Trials for Various Conditions
The investigators seek to examine the effect of add-on N-Acetyl-Cysteine (NAC) in the early phase of schizophrenia spectrum illness in collaboration with researchers Kim Do, PhD, and Philippe Conus, MD in Switzerland. Modifications of brain structure are thought to occur during the pre-illness phase and around the transition to psychosis. Therefore, studying new treatments that could target changes occurring during this period is of critical importance. Aims: Does add-on NAC treatment in early psychosis influence: * positive and negative symptoms * extrapyramidal side-effects of other medication * plasma concentration of glutathione * Mismatch Negativity, a physiological marker
The purpose of this study is to test the safety and effectiveness of talnetant vs. risperidone vs. placebo in reducing positive and negative symptoms in acutely psychotic schizophrenia patients.
The purpose of this study is to evaluate maintenance neuroleptics for Schizophrenic patients who are cocaine abusers.
The purpose of this open-label study is to evaluate the long-term (6-month) safety and tolerability of extended-release paliperidone, an atypical antipsychotic, given in flexible dosages to adolescents with schizophrenia.
The purpose of this study is to evaluate the cognitive processes of participants with schizophrenia, participants with nervous system and mental disorders, and healthy volunteers. Participants in this study will undergo cognitive tests of attention, memory, attention. Participants with attention deficit hyperactivity disorder (ADHD), traumatic brain injury (TBI), bipolar disorder, and Alzheimer's disease (AD) will be compared with participants with schizophrenia. A group of healthy adults and children will undergo cognitive tests to further delineate the degree of impairment in schizophrenia and neurological disorder participants.
This study will evaluate the effectiveness of a computer-based cognitive enhancement program plus a work therapy program at improving productivity, work performance, and quality of life in schizophrenic individuals.
