Phenylketonuria is an autosomal recessive hereditary disease caused by the lack of the enzyme phenylalanine hydroxylase (FAOH) or dihydropterine reductase (DHPR), which causes an increase in blood levels of phenylalanine and other metabolites such as phenylpyruvate, phenylactate and phenylacetate, proceeding from alternative metabolic pathways and causing damage to the central nervous system. Characterized by severe mental and psychomotor retardation, the main treatment of the disease is to maintain strict metabolic control from its detection at birth using phenylalanine free diets and supplemented with the rest of amino acids, vitamins and minerals. However, there is currently controversy as to whether this dietary restriction should be continued throughout life or may be disrupted around the first decade of life, once the period of maximum development of the central nervous system has passed. Following a case, the objective of this report is to perform a review of the convenience or not of dietary restriction in adulthood in these patients.
Key Words: Phenylketonuria, dietary restriction, adulthood, acute neurological complications.
