My son is about 16 years old, he is suspected as Bipolar I (mania) or schizoaffective disorder, He used Valproat 650mg/day to stablise his mode and abilify 2.5mg/day to treat his psychosis. Valproat seams not effective, abilify is very effective and he lives a normal life, but he got blurred vision, his doctor had to stop abilify. Can he stop valproat and use abilify alone to treat his illness? He tried olanzapine 2.5mg/day with valproat 650mg/day, but not effective for one week, olanzapine was stopped. Can we try olanzapine 5mg/day with valproat for longer time?
