[Ailist] Ai diet and undiagnosed phenylketonuria

[Kate Start]

Dear Aiers, this is really a long shot, its just in case.
There is a syndrome called Phenylketonuria. It is usually successfully diagnosed and treated in childhood. If the syndrome has not been diagnosed in childhood, adult behaviour is extremely challenging. Does  anyone know of success in using a low phenylanaline diet to enhance behaviour in adults who have not been diagnosed? (or in deed any other successful interventions)
Many thanks in anticipation
Best wishes
