Filter by:In recent years, the prevalence of severe mental disorders in China has continued to grow, and the burden of disease in society has continued to rise. In order to improve the prognosis of patients with severe mental disorders and reduce the risk of disease relapse or readmission, researchers established a cohort based on the Ningbo Mental Health Information System in Ningbo, a sub-provincial city in the southern wing of the Yangtze River Delta of China, with a resident population of more than 9 million, and linked it to the residents' health records, and through the data linkage obtained data on patients in the full cycle of pre-diagnosis, diagnosis, follow-up, disease changes and death, realising full-cycle management of patients with severe mental disorders. Currently, NEED has accumulated data on more than 50,000 patients with severe mental disorders and obtained multi-dimensional longitudinal information through long-term follow-up and data linkage. All diseases follow the World Health Organization International Classification of Diseases 10th Edition (ICD-10) for clinical coding, and available data include baseline demographics, past history, family history, social functioning deficit screening scale scores, risk assessment, and so on and longitudinal health information from electronic health records (EHR), providing a solid data base for future real-world studies.
Background: - Autism spectrum disorders (ASDs) are a group of developmental disorders that affect communication, social interaction, and behavior. Relatively little is known about the relationship between genetics and behavior among these individuals and their close relatives. Researchers are interested in using interviews and rating scales to better understand these issues, as well as collecting brain scan data and genetic samples for testing and comparison. - By comparing test results and genetic samples from healthy volunteers, people with ASD, and parents (or caregivers or legal guardians) of the first two groups, researchers hope to better understand the neuroscience of ASD. Objectives: - To learn more about the brain in healthy people and in people with autism spectrum disorders. - To study genes that might be involved in autism spectrum disorders by collecting DNA samples from participants. Eligibility: The following groups of participants will be eligible for the study: - Individuals between 5 and 89 years of age who have autism spectrum disorders. - Healthy volunteers between 5 and 89 years of age. - Cognitively impaired children between 5 and 17 years of age. - Parents/caregivers/legal guardians of individuals in the above three groups. Design: - Participants will visit the National Institutes of Health Clinical Center for research tests, which will be administered over multiple visits. Researchers will determine the specific tests to be administered based on the medical history of the study participant. - Researchers will study the brain through interviews, tests of thinking and memory (neuropsychological tests), brain imaging with magnetic resonance imaging (MRI), and magnetoencephalography (MEG). - The study will also collect blood or saliva to obtain a DNA sample.
This is an open randomized controlled study in children with mental retardation and refractory epilepsy in which treatment with ketogenic diet (KD) is compared with treatment with the antiepileptic drug (AED), not tried by the patient before, which we consider to be the most appropriate AED for the patient.
Self-injurious behavior is behavior in which a person hurts or harms himself. This behavior sometimes occurs in people with mental retardation or autism. This study will evaluate self-injurious behavior in people with mental retardation or autism and will test the effectiveness of new treatments.
