Clinical and electrophysiological findings in patients with phenylketonuria and epilepsy: Reflex features

Abstract

Objective: Phenyl ketonuria (PKU) is the most common form of amino acid metabolism disorders with autosomal recessive inheritance. The brain damage can be prevented by early diagnosis and a phenylalanine-restricted diet. Untreated or late-treated patients may show mental retardation and other cognitive dysfunctions, as well as motor disability and/or epilepsy.
