Filter by:Mental disorders have been shown to be associated with a number of general medical conditions (also referred to as somatic or physical conditions). The investigators aim to undertake a comprehensive study of comorbidity among those with treated mental disorders, by using high-quality Danish registers to provide age- and sex-specific pairwise estimates between the ten groups of mental disorders and nine groups of general medical conditions. The investigators will examine the association between all 90 possible pairs of prior mental disorders and later GMC categories using the Danish national registers. Depending on whether individuals are diagnosed with a specific mental disorder, the investigators will estimate the risk of receiving a later diagnosis within a specific GMC category, between the start of follow-up (January 1, 2000) or at the earliest age at which a person might develop the mental disorder, whichever comes later. Follow-up will be terminated at onset of the GMC, death, emigration from Denmark, or December 31, 2016, whichever came first. Additionally for dyslipidemia, follow-up will be ended if a diagnosis of ischemic heart disease was received. A "wash-out" period will be employed in the five years before follow-up started (1995-1999), to identify and exclude prevalent cases from the analysis. Individuals with the GMC of interest before the observation period will be considered prevalent cases and excluded from the analyses (i.e. prevalent cases were "washed-out"). When estimating the risk of a specific GMC, the investigators will consider all individuals to be exposed or unexposed to the each mental disorder depending on whether a diagnosis is received before the end of follow-up. Persons will be considered unexposed to a mental disorder until the date of the first diagnosis, and exposed thereafter.
This prospective cohort study will determine the natural history of fetal exposure to Zika virus (ZIKV) and its effects on the fetus and newborn with emphasis on neurodevelopment outcome. Exposure of the fetus will be determined by maternal symptomatology, RT-PCR ZIKV (blood and urine) and serologic test specific for ZIKV. Neonates will be classified according to trimester of infection and as exposed and unexposed to ZIKV.
Frailty is a age dependent physiological state of vulnerability. Frailty is screened by the phenotypic model (5 clinical criteria) or the cumulative model (various clinical and biological criteria). Currently, aging with autism spectrum disorder and mental retardation (ADS-MR) is poor described. Nevertheless many data indicate that people with ADS-MR may present an early aging. Principal aim of this study is to determine if frailty in people with ADS-MR aged over 20 years depend on age. Secondary aims are to evaluate frailty prevalence, to describe with details health according to age, and to verify the frailty index validity for predicting falls, hospitalisation and death, in this population of ADS-MR patients aged over 20 years. This monocentric and prospective study will include 60 ADS-MR patients aged over 20 years and living in Languedoc-Roussillon's medico-social care homes. Patients are evaluated at the time of inclusion. Frailty index is calculated from 104 clinical and biological criteria. Furthermore the investigator staff collect data about ADS severity (CARS), adaptative and intellectual functionning (Vineland), and psychiatric and somatic comorbidities (Reiss scale, DSQIID and CIRS). Falls, hospitalisations or death occurrence is then collected every year during 5 years. The connection between frailty index and age will be studied using linear regression. The frailty index validity will be analysed using ROC curves. Modelisation of the falls, hospitalisations or death risk in the 5 years after the initial evaluation will help in identification of the more frailty predictive criteria.
Background: - Prader-Willi syndrome (PWS) and MC4R genetic mutations are two conditions that can cause problems with appetite regulation. People with PWS often have behavior and thinking problems. People with MC4R mutations may have problems with attention. These problems may be related to Brain-Derived Neurotrophic Factor (BDNF), a protein that is important for brain development. Researchers want to study people with PWS and MC4R mutations to see how BDNF is involved in these conditions. Specifically, body weight and brain function will be studied, and compared with healthy volunteers. Objectives: - To study how BDNF affects body weight and brain function in people with PWS and MC4R mutations. Eligibility: - Individuals of any age who have Prader-Willi syndrome or MC4R genetic mutations. - Healthy volunteers of any age to act as control participants. Design: - Participants will be screened with a medical history and physical exam. Height, weight, and waist/hip circumferences will be measured. Blood samples will be taken for genetic and other tests. - Participants will fill out questionnaires about eating habits, pain perception, and sleep behavior. - Participants will keep a 3-day food diary to record all food and drinks eaten. - Tests and questionnaires will be given to study thinking, speech, movement, behavior, and mood. Some tests will be done on a computer; other tests will be on paper. Tests may also involve performing tasks with blocks and other objects. - Participants may have other tests as directed. These will include hot and cold sensitivity tests, imaging studies like x-rays, and measurements of body fat and water content. - Treatment will not be provided as part of this study.
Resistance exercise (RE) has been proposed as a possible strategy for prevention and rehabilitation of diseases. The increase in both muscle strength and the ability to perform tasks of day-to-day work environment and are well-characterized benefits of this type of training. The literature has been investigating the effectiveness of the RE for humans, yet few studies have been conducted with intellectual disabilities (ID). It is known that a sedentary lifestyle contributes to the development of cardiovascular disease, type 2 diabetes, hypertension, arthritis, and stress, depression, difficulty in socializing, stigma and discrimination. In particular, the ID is less active and is more likely to develop secondary diseases.
The purpose of this study is to find the relationship between the stage and quality of developmental delay during infancy and toddler age, and the final diagnosis that the child gets a few years later (MR, type of PDD, CP or comorbidity of a few disorders).
A whole of school intervention with daily physical activity and healthy food for students with intellectual disabilities. The aim is to provide plenty of concrete examples of healthy life style choices and using school personnel and peers as role models. This will presumably result in healthier weight, better fitness and not least in new familiar healthy habits.
The aim of this study is to evaluate the effect of valproate on the required dose of propofol for sedation in patients with mental retardation.
Comparative genomic hybridization (CGH) array technology has been used in numerous studies on mental retardation, and few chromosomal abnormalities have been identified in patients. Because chromosomal abnormalities have still been associated with obesity, we can expect that syndromic obesity is also associated with small deletions/duplications. Characterization of deleted or duplicated loci in these obese patients would mean that these loci include genes implicated in obesity. This will permit to propose new gene(s) involved in obesity.

The aim of this study is to evaluate benefits of the method of dental sedation using Target controlled infusion (TCI) combined with Bispectral index (BIS) monitoring in patients with Mental Retardation and challenging behavior.
