Question
How long does the treatment for phenylketonuria take? What are the clinical diagnostic symptoms?
Answer
The main clinical manifestations include intellectual disability, tics, and increased pigmentation. Infants are born normal. After changing diapers, symptoms usually reappear between 3 to 6 months, and become apparent at 1 year old. If not treated promptly, it can cause varying degrees of harm to the brain or nervous system, bringing pain to the patient and even affecting intelligence. This disease has always been one of the routine screening projects for neonates in the obstetrics department.
