NCT02205684
Physical health problems are common in schizophrenia with a two- to three-fold increased morbidity and mortality rate, resulting in a 20 years reduction in life expectancy. A genetic vulnerability for developing cardiovascular disease has been documented in these patients, and many lifestyle factors also negatively influence physical health. Patients with schizophrenia are likely to smoke, are physically inactive and overweight, suffer from malnutrition due to unhealthy diet, and have reduced cardiorespiratory fitness. Moreover, these patients have increased risk of developing diabetes mellitus type II and metabolic syndrome. These aspects demonstrate the need for multi-disciplinary treatments of patients with schizophrenia and underline the need for addressing their physical health. Poor physical fitness seems to be associated with exacerbated negative symptoms and increased cognitive dysfunction in patients with schizophrenia. However, evidence on physical activity and its consequences in schizophrenia is scarce. In this randomized controlled trial we investigate the effects of high intensity training in outpatients with schizophrenia on psychotic symptoms and well-being, cognition and cortical structure, tobacco smoking and substance use, in addition to metabolic indices.
NCT01369966
Background: \- Smoking is associated with serious health risks. People who have mental illness are more likely to smoke. Researchers are studying the brain circuits linked with smoking and nicotine craving. This study will look at whether a specific brain circuit can explain the high rate of smoking in people with schizophrenia. Objectives: \- To study brain activity in smokers and nonsmokers with and without schizophrenia, as well as their family members. Eligibility: * Current smokers (at least 100 cigarettes in the past year) and nonsmokers between 18 and 62 years of age in one of the following groups: * Have been diagnosed with schizophrenia. * Family members of those with schizophrenia. * Healthy adults with no history of severe mental illness or brain trauma. * Family members of the healthy adults. Design: * People in the study will be screened with a physical exam, medical history, questionnaires, and blood tests. * They will have up to three visits: the screening visit and two study visits (each given 1 year apart). * At the first study visit, those taking part will be trained in the tests they will do during the magnetic resonance imaging (MRI) scan. Then they will have the MRI scan. * After the first study visit, current smokers will receive phone calls from the study researchers every other month for 1 year. They will be asked about their smoking habits. * At the second study visit, current smokers and some nonsmokers will have another MRI scan and the same tests as before. * Current smokers will receive a final phone call 1 year after the second study visit. They will be asked to give information about their smoking habits.
