Prader-Willi Syndrome (PWS) is a rare disorder, sharing common genes with autism and schizophrenia; patients with PWS are at very high risk of developing severe psychiatric illnesses and behavioral problems, however, the underlying neurobiology that places them at-risk is yet unknown. Here we propose a cross-sectional, multi-faceted brain imaging study in children with PWS. The results of the proposed project will hopefully reveal biomarkers for early intervention and contribute to optimizing the management of psychiatric illnesses in PWS, improving quality of life of these patients as well as their caregivers, and better understanding of mechanisms of psychiatric illnesses.


A research blog post taking a closer at one of the publications from this project on how “Brain imaging shows structural differences between the PWS vs. non-PWS brain” can be found here.
