Behavioral and emotional manifestations in a child with Prader-Willi syndrome.

Prader-Willi syndrome is a neurodevelopmental disorder characterized by mental retardation and distinct physical, behavioral, and psychiatric features. Maladaptive behaviours, cognitive impairment, and impediments in speech and language seriously affect the early development and long-term functioning of individuals affected by the illness. We present a case of a 9-year-old child with Prader-Willi syndrome whose behavioural symptoms were treated with low-dose antipsychotic medications.
