Abstract

Sleep patterns have been investigated in a "new variant" Phenylketonuric child suffering from a deficit in dihydropteridin reductase with consequent deficit of 5-HT and dopamine. This child has been studied in four conditions: when receiving a diet poor in phenylalanine, after an intraveinous perfusion of phenylalanine and 10 days and 6 months after a treatment with L-DOPA and 5-HTP. In the three first conditions, no modifications in the amount of each state of sleep were observed; in the fourth condition the amount of paradoxical sleep was very low.

Key words
