Age with Health is a longitudinal cohort study aimed to examine trajectories of health, disability and wellbeing and their determinants for Spanish ageing population. Two waves have carried out so far. Wave 1 (2011-2012) and Wave 2 (2014-2015). Wave 3 will be conducted 2018, including also a new cohort of participants (Called 2018 Cohort). The study will provide reliable measures of population ageing and adult health in Spain - and will provide the basis for cross-country comparisons with longitudinal studies conducted in other countries.
Background: Cocaine use disorders (CUD) is a complex brain disorder, involving several brain areas and neurocircuits. Effective treatments for CUD are still needed. Repetitive transcranial magnetic stimulation (rTMS) stimulates non-invasively parts of the brain. Preliminary data suggest that rTMS may help reducing cocaine craving and consumption. Researchers want to learn how the brain and the drug-seeking behavior may change with this treatment. Objectives: To test if rTMS can reduce cocaine craving and use, and also affect several mood, behavioral and cognitive alterations associated with prolonged cocaine use. Eligibility: Healthy, right-handed adults ages 18-65 who do have cocaine use disorder (moderate to severe). Design: This is a randomized, double-blind, sham-controlled study. The study includes three phases: 1) a rTMS continued treatment phase; a rTMS follow-up; and a no rTMS follow-up. Prior to participating, participants will be screened with: - Questionnaires - Medical history - Physical exam - Urine tests - MRI (structural) After being enrolled, baseline behavioral and imaging data will be collected. In particular, participants will undergo: - Questionnaires - Functional MRI During the continued rTMS phase, participants with cocaine use disorder will be randomized to receive real or fake rTMS. Repetitive TMS will be delivered during 10 outpatient treatment days, over 2 weeks (5 days/week). Following this phase, subjects will have 12 follow-up visits (once/weekly), during which they will receive rTMS, and behavioral and imaging assessments will be performed. At the end of the rTMS follow up period, participants will further receive 3 follow up visits (once a month), during which rTMS will not be performed, but behavioral data will be collected. Treatment includes: - rTMS: A coil is placed on the head. A brief electrical current passes through the coil. At each visit, participants will receive two rTMS sessions, with a 1hr interval between sessions. At the beginning of each rTMS session, they view cocaine-related images for few minutes. - MRIs at baseline and at follow-up visit #12: Participants lie on a table that slides into a cylinder that takes pictures of the brain. They respond to images while in the scanner. - Repeat of screening tests and questionnaires - Urine toxicological screen
This study aims to identify unusual experiences and psychiatric symptoms that indicate a heightened risk for severe mental disorders - especially psychoses. It is important to develop reliable questionnaire methods that are cost-effective in first-stage screening, leading to in-depth assessments and targeted care. However, existing psychosis-risk questionnaires are limited in content, intended for adults, and have been insufficiently tested for actual predictive value. Therefore we will collect a new, large dataset from an unselected group of adolescents entering psychiatric care in three major urban areas of Finland. Comprehensive national health care registers will be used to assess how well the selected experiences and symptoms predict the participants' mental health over the following few years.
Since capability for suicide involves overriding potential pain, and the opioid system plays a strong role in controlling pain perception, it follows that capability for suicide may be impacted by the opioid system. The goal of the proposed research is to identify the neural network underlying capability for suicide in order to determine if it can be a target for identifying high-risk individuals and for intervention.
Risperidone is a selective monoamine receptor antagonist. It plays an antipsychotic effect by antagonizing 5-HT2 / D2 receptor. As a second-generation antipsychotic drug, risperidone is metabolized to 9-hydroxy Risperidone in the body very quickly. There are individual differences in the pharmacokinetics and pharmacodynamics of risperidone. For example, CYP2D6 genotype can greatly affect the metabolism of risperidone, and provide evidence for adjusting the type and dose of medication to treat Schizophrenia. In this study, we will verify the correlation between the polymorphisms of genes related with risperidone drug metabolites, drug transporters, drug targets and drug metabolism, pharmacodynamics, adverse reactions in Chinese population, providing basis for clinical rational use of risperidone.
Common mental health disorders such as anxiety and depression are leading causes of sickness absence and disability in Norway. Despite tremendous costs for individual and society, effective treatment is lacking. Mental health interventions do not typically target work situation, despite its importance for patient well-being. On a policy level, effective measures are impeded by a paucity of scientific data, and programs designed to address the issue such as Faster Return to Work ("Raskere tilbake") lack evaluation. The present project will test the effectiveness of Metacognitive therapy and work-focused interventions for reducing sick leave in patients with common mental disorders.
The originality of the MOCITRAINING study lies in the integration of infant and maternal care during the pediatric consultation and the assessment of the impact of this type of care in the short and medium term on The MOCITRAINING program could contribute to improving the quality of parent-child interactions.
This is a prospective observational study investigating the utility of 7 Tesla MRI to quantify nigrosome1 signal in a cohort of individuals with recent onset Parkinson's disease and in at-risk cohorts at a premotor state of Parkinson's disease.
Cognitive-behavioral therapy (CBT) and social skills training (SST) are recommended psychological interventions to improve symptomatology and functional recovery in psychosis. In addition, CBT may reduce hyperactivation of the brain structures responsible for the stress response. In patients with early onset psychotic disorder (EOP) there are not any previous controlled study that has analyzed the efficacy of this type of intervention. The aim of this study is to investigate efficacy of CBT + SST in symptomatic and functional improvement after the treatment in patients with EOP. The study will also examine the potential effect of the intervention on neurobiological stress markers.
