Improving social functioning in Prader-willi syndrome (year 2)

Abstract Social isolation and impaired social cognition underpins loneliness, depression and anxiety, contributes to poor health and reduced longevity. They also are associated with such cognitive consequences as impaired executive functioning, cognitive decline, a bias towards negative, depressive thinking, and oversensitivity to perceived social false

ComuFaces: The perception of communicative faces by infants with Prader-Willi syndrome (year 2)

Neuropsychological studies have detailed several cognitive deficits in Prader-Willi Syndrome (PWS), among which the observation of altered social interactions, with notable difficulty in interpreting and responding to social information. The integration of the information from the face and the voice is important for our social communication as false

Comufaces: The Perception of Communicative Faces by Infants with PWS (Year 2)

Neuropsychological studies have detailed several cognitive deficits in Prader-Willi Syndrome (PWS), among which the observation of altered social interactions, with notable difficulty in interpreting and responding to social information. The integration of the information from the face and the voice is important for our social communication as false

Systematic Investigation of Early Social Cognitive Processes and the Feasibility of Intervention

For Year 1, our project aims were: 1) to characterize the social, cognitive, and affective processes in preschoolers with PWS (by genetic subtype), in comparison to preschoolers with ASD and typically developing children, and 2) to pilot a remotely delivered parent education program to determine if it would be feasible and effective for families false

Neural mechanisms of oxytocin-enhanced infant feeding and social behavior development

This project uses infant mice to understand the mechanism of a promising treatment for PWS. Oxytocin (OXT) regulates feeding and social behavior. In mouse research and recent clinical trials with infants and young children, OXT seems to improve the core feeding and social behavior disturbances of PWS. In humans, OXT is effective when it is given false

A mindfulness-based intervention for temper outbursts in Prader–Willi syndrome

Temper outbursts are one of the most commonly reported behavior problems of children, adolescents and adults with PWS. Outbursts cause increased stress for families and costs for the community. Despite this, there is currently no known treatment. Meditation on the Soles of the Feet (SoF) is a mindfulness-based intervention designed specifically to false

Evaluating factors that may affect the efficacy of intranasal oxytocin treatment in PWS

Recent studies with oxytocin treatment in PWS have yielded inconsistent results. Intranasal administration of oxytocin by the Toulouse group decreased disruptive behaviors in patients with PWS, but a recent randomized trial in Australia of adolescents and adults of intranasal oxytocin (IN-OT) found no effect on syndrome-specific behavior in false

Proof of concept study of vagus nerve stimulation from an external device in PWS (year 2)

The hypothesis set out in our original application is that t-VNS given over time and following a protocol established for its use in epilepsy, will prevent the prolonged and debilitating temper outbursts and associated emotional dysregulation that characteristically affect people with PWS. We further propose that any improvements in behavior are false

Wake promoting effects of oxytocin

Caregivers, physicians and patients with PWS report that daytime sleepiness in PWS significantly disrupts daily life. However, the underlying cause of excessive daytime sleepiness in PWS is unknown. Dr. Scammell’s group is exploring the contribution of reduced neuronal function in the hypothalamus region of the brain, specifically, oxytocin/orexin false

Improving social functioning in Prader-Willi syndrome

People with intellectual or developmental disabilities, including Prader-Willi syndrome (PWS), are at heightened risk for social exclusion and isolation. This underpins loneliness, depression and anxiety, contributes to poor health and reduced longevity. This project will recruit 50 young adults with PWS into an intensive, 10-week group false
