psychiatric clinic/facility

Does anyone know a good place in Brussels for a patient with psychosis? A family member (in his 30s) was hospitalised with psychotic symptoms (delusions, hallucinations, probable diagnosis = bouffee delirante (FR)) for the first time in his life 12 days ago. However, he is not improving where he is now (clinic Fond'Roi in Uccle), on the contrary. He is not getting proper professional help at that place and we need to move him from there. This is urgent! Thank you in advance!
