Recent neuropsychological studies have suggested that patients with early-treated phenylketonuria (PKU) and normal intelligence have a specific deficiency in solving complex spatial problems. In the present study a task involving the assembly of various shapes was used to compare the performance of 16 PKU patients and 11 sibling controls. Error rates generally were higher and response times slower among the PKU patients, but greater complexity did not produce differential changes in accuracy or… CONTINUE READING
