Summary
Compulsive behaviors common in childhood persist into adolescence for individuals with Prader-Willi syndrome (PWS). These PWS compulsions, particularly insistence on sameness, do not decrease with age.
Area of Science:
- Neurodevelopmental Disorders
- Child and Adolescent Psychiatry
- Behavioral Science
Background:
- Prader-Willi syndrome (PWS) is associated with a higher incidence of obsessive-compulsive disorder (OCD).
- Understanding compulsive-like behaviors in PWS is crucial for effective management and intervention.
Purpose of the Study:
- To investigate the characteristics and prevalence of compulsive-like behaviors in individuals with Prader-Willi syndrome.
- To examine how these behaviors change or persist from childhood into adolescence within the PWS population.
Main Methods:
- The study utilized the Childhood Routines Inventory, completed by parents.
- Participants included 50 individuals with PWS (aged 5-18) and 50 typically developing children (aged 4).
Main Results:
- Childhood compulsive behaviors remain prevalent in older children and adolescents with PWS.
- The PWS group showed significantly higher levels of compulsive behaviors related to insistence on sameness, irrespective of age, gender, or cognitive status.
- A distinct, age-independent pattern of PWS compulsivity was identified, potentially linked to other PWS symptoms.
Conclusions:
- Childhood compulsions do not naturally diminish with age in individuals with Prader-Willi syndrome.
- Distinguishing between normative childhood rituals and pathological compulsive features in PWS is challenging.
