Our outcomes rather aid that the peripheral administration of BH4 brings about increased synthesis and storage of DA, then willing to be produced on stimulation.

The harmful impact of Phe accumulation in blood and brain is greatest witnessed in untreated sufferers with PKU who establish irreversible neurological impairment and psychiatric signs and symptoms if subjected to HPA [five].
