“…The disease incidence is 1: 10,000 to 30,000 births 1.2. The cognitive and behavioral phenotype observed in people with PWS is characterized by frequent episodes of hyperphagia, stealing food, tantrums, lying behavior, mood swings, anxiety, sadness, aggression and auto aggression, stubbornness and repetitive speech, hypersomnia, compulsive behaviors, deficits in cognitive abilities such as attention and executive functions (especially inhibitory control, working memory and self-regulation) and deficits in visuospatial skills [3][4][5][6][7] . Of these described characteristic phenotypes, the problems most difficult to manage are hyperphagia; stubborn behavioral patterns; challenging, aggressive, oppositional and manipulative behaviours; food theft and lying, which become more frequent and severe with increasing age [8][9][10][11] . Parents and caregivers of people with PWS are routinely faced with two types of problems; the control of access to food to avoid and/or minimize other health problems (such as obesity, scoliosis, and cardiovascular and endocrine illnesses) 12 , and family burden, especially on the primary caregiver, due to the difficulties in the management of behavioral problems that start from early childhood 13,14,15 .…”
