Quizplus · Accepted Answer

Phenylketonuria (PKU) is a genetic disorder that causes a buildup of phenylalanine in the body, leading to brain damage and intellectual disability. The most effective treatment is a strict and lifelong low-protein diet that restricts phenylalanine intake. This diet has been shown to prevent or limit the cognitive impairment typically associated with PKU. Cognitive stimulation, surgery to reduce brain swelling, and antipsychotic drugs are not appropriate or effective treatments for PKU.
