Active clinical trials for "Schizophrenia"

This study seeks to determine whether adult, non-psychotic, first-degree relatives of schizophrenic patients who show specific neurocognitive deficits and negative symptoms will show improvements in these areas following a 6-month, double-blind trial of a low dose (up to 2.0 mg) of risperidone.

Abnormalities in the ability to distinguish events in time may have a great impact on everyday life. The main objective of the study is to evaluate the magnitude of the temporal windows in schizophrenia, i.e. the time interval during which two events are perceived as synchronous. The investigators test the hypothesis that these temporal windows are enlarged, and check the relationship between this impairment and disorganization symptoms, in order to explore the link between this cognitive impairment and clinical symptoms. They explore also the neurobiological bases of the impairment by means of electroencephalogram (EEG) recordings. Event-related potentials (N50) will reveal whether or not the coding of the stimuli has the same temporal characteristics in patients and controls. The distribution and amplitude of oscillatory activities will be analyzed as a function of the synchronous or asynchronous response of the subject, thus allowing to explore the links between synchrony perception and neuronal synchronization phenomena.

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.

Individuals with schizophrenia have important and persistent deficits in multiple neurocognitive domains as well as in the Social Cognition (SC). SC refers to the mental operations underlying social behavior, and it is understood as a multidimensional construct that comprises emotional processing (EP), social perspective and knowledge, attributional bias and theory of mind (ToM) or mentalizing. Mentalizing and EP skills have been the two most studied subdomains of SC in schizophrenia. Both domains have been found to be impaired in chronic schizophrenia patients as well as in patients in early stages of the illness. In this context, although negative symptoms may play and important role, females seem to perform better than males in ToM and EP tasks, suggesting the presence of gender differences in the SC skills in patients with schizophrenia. However, to our knowledge, there are no studies that have explored the gender-related differences between cognitive and affective ToM and its relationship with the EP performance in schizophrenia patients of recent diagnosis comparing with healthy subjects. In this line, the main objective of this project is to analyze the influence of gender in the cognitive and affective ToM abilities, in a group of patients with schizophrenia in early stages of the illness comparing with healthy subjects. Secondarily, this study pretends to explore the association between EP skills and affective ToM tasks performance in males and females with and without recent diagnosis of schizophrenia.

This study is a disease-based registry designed to follow patients with a DSM-IV-TR (Diagnostic and Statistic Manual of Mental Disorders, Text Revision) diagnosis of schizophrenia, schizoaffective disorder, or schizophreniform disorder treated in usual care settings for up to 5 years. The registry seeks to describe the course of disease in schizophrenia, including cognitive function and negative symptoms, its treatment, and its burden of disease for participants, caregivers, clinicians, and society as a whole.

The primary purpose of the study is to compare the rate of hospitalization associated with psychotic relapse in participants with schizophrenia treated one year before with oral antipsychotics and one year after with long acting injectable atypical antipsychotics.

Patients with schizophrenia are more likely to have metabolic syndrome compared to general population. The criterion for metabolic syndrome in Asian people including: elevated waist circumference (male ≥ 90cm, female ≥ 80cm), elevated triglycerides ≥ 150mg/dL, reduced HDL cholesterol: male < 40mg/dL, female < 50mg/dL, elevated blood pressure: ≥ 130/85 mmHg, elevated fasting glucose: ≥ 100mg/dL. Several factors have been found to be associated with metabolic syndrome in schizophrenia, e.g. age, antipsychotic drugs, smoking, family history of metabolic disorder, stress, and quality of life. However, little is known about the prevalence of and factors associated in Asian. This study aimed to: Identify the prevalence of metabolic syndrome in patients with schizophrenia. Identify the factors associated with metabolic syndrome in patients with schizophrenia.

Schizophrenia is a severe mental illness associated with excess mortality and affecting nearly 1% of the population. The average life expectancy for patients diagnosed with schizophrenia has been 55-60 years through the last generations in Denmark, while the general population has over the same period of time experienced an increase in life expectancy. As a result, the standardized mortality rate for patients with schizophrenia has increased markedly over the last three decades and is currently a major public health concern. Causes of death are mainly cardiovascular disease and patients diagnosed with schizophrenia has a relative risk of cardiovascular disease that is about 2-fold higher than the general population.

The purpose of this study is to investigate the mean number of schizophrenia-related hospital admissions, in adult participants with schizophrenia, occurred during 12 months before and 12 months after initiation of Paliperidone Palmitate 1-month formulation treatment.

This study is designed to find quantitative Electroencephalogram(qEEG) biomarkers to predict Electroconvulsive Therapy(ECT) Response in Schizophrenia
