The objective is to develop and test, through an iterative process, an intervention to address and support the development of infants with a confirmed diagnosis of a neurogenetic disorder with associated developmental delays or intellectual and developmental disabilities. The proposed project will capitalize and expand upon existing empirically based interventions designed to improve outcomes for infants with suspected developmental delays. Participants will be infants with a confirmed diagnosis of a neurogenetic disorder (e.g., fragile X, Angelman, Prader-Willi, Dup15q, Phelan-McDermid, Rhett, Smith Magenis, Williams, Turner, Kleinfelter, Down syndromes, Duchenne muscular dystrophy) within the first year of life and their parents/caregivers. The intervention, called the Parent and Infant Inter(X)action Intervention (PIXI) is a comprehensive program inclusive of parent education about early infant development and the neurogenetic disorder for which they were diagnosed, direct parent coaching around parent-child interaction, and family/parent well-being support. The protocol includes repeated comprehensive assessments of family and child functioning, along with an examination of feasibility and acceptability of the program.
Early Check provides voluntary screening of newborns for a selected panel of conditions. The study has three main objectives: 1) develop and implement an approach to identify affected infants, 2) address the impact on infants and families who screen positive, and 3) evaluate the Early Check program. The Early Check screening will lead to earlier identification of newborns with rare health conditions in addition to providing important data on the implementation of this model program. Early diagnosis may result in health and development benefits for the newborns. Infants who have newborn screening in North Carolina will be eligible to participate, equating to over 120,000 eligible infants a year. Over 95% of participants are expected to screen negative. Newborns who screen positive and their parents are invited to additional research activities and services. Parents can enroll eligible newborns on the Early Check electronic Research Portal. Screening tests are conducted on residual blood from existing newborn screening dried blood spots. Confirmatory testing is provided free-of-charge for infants who screen positive, and carrier testing is provided to mothers of infants with fragile X. Affected newborns have a physical and developmental evaluation. Their parents have genetic counseling and are invited to participate in surveys and interviews. Ongoing evaluation of the program includes additional parent interviews.
Prader-Willi Syndrome (PWS) is a multisystemic genetic disease characterized by hypotonia, mental retardation, hyperphagia, and uncontrollable hunger due to hypothalamic dysfunction, caused by dysregulation of genes located in chromosome 15q11-q13. The goal of this study is to evaluate the effects of Transcranial Direct Current Stimulation (tDCS) on hyperphagia and behavior in PWS. Forty children and adolescents (11-24 years) with clinical and cytogenetic-molecular diagnosis of Prader-Willi syndrome will be assessed before and after 10 tDCS session with: Food Craving Questionnaire (FCQ), Aberrant Behavior Checklist (ABC), Dykens hyperphagia questionnaire. Caregivers self-reported the participant's behaviors at home and, lately, they will be categorized and quantified. tDCS will be applied for 20 minutes with electrodes of 25cm2 wrapped in cotton material soaked in saline solution. The anode at the left dorsolateral prefrontal cortex (F3) and the cathode at the contralateral area (F4). Children from 11-12 years will receive a current of 1mA; above 13 years, 2mA.
