[Psychological management of a patient with Prader Willi syndrome: case study of a young Moroccan girl].

Prader Willi syndrome is a rare genetic disease. Symptoms include binge eating disorder associated with the risk of morbid obesity, learning difficulties and behavioral problems or even major psychiatric disorders. The purpose of this case study is to conduct a literature review on Prader Willi syndrome and to highlight its impact on daily life, both on physical and mental health, as well as its management. We report the case of an 11-year old Moroccan girl presenting with Prader Willi syndrome. She was assisted in performing activities of daily living by using a comprehensive biopsychosocial approach which improved her quality of life. We here emphasize the primary and central role of the psychotherapist in the treatment of patients with Prader Willi syndrome which is based on counselling, motivational interviewing and cognitive behaviour therapy techniques. Prader Willi syndrome is a disease with severe psychiatric symptoms. Patient's care requires multidisciplinary team approach involving psychologist or psychiatrist.
