Prader-Willi syndrome (PWS) is a neurodevelopmental disability characterized by hypotonia and failure to thrive during infancy, then the development of hyperphagia, hypogonadism, cognitive impairments and distinct physical and behavioral characteristics. Through our patient’s case and literature review, we’re willing to showcase the different psychiatric disorders that can occur in patients with PWS, and show treatments that are specific and/or effective. Our patient is a 19 year old Caucasian male, diagnosed with Prader-Willi syndrome through its clinical elements, has also type 1 diabetes and sent by the endocrinology unit to the psychiatry department to take charge its behavioral disorders. Several studies investigating social and communication skills have shown people with PWS to have difficulties with care, receptive and expressive language skills, interpreting emotional valence in faces, understanding personal space and a developmental delay in theory of mind. Temper outbursts, temper tantrums and skin picking are often seen in PWS. Different drugs can be used such as second generation of anti-pyschotics, antidepressants and oxytocin and others.
