my son is suffering from OCD problem for more than 15 years. He is 29 years old.has done study upto high school only and is not doing anything .For last many yrs he is on following medication: Pacitane -1 ----------OD Resperidone-1------BD Prodep-20------------OD However, we dont find much improvement / control over his repetitive behaviour and anger.He gets extremely furious over petty matters specially whenever his unending demands are declined and creates a lot of fuss in the family.He sometimes , while in extreme fit of anger, pretends to kill himself by holding a kitchen knife in his hand. Pl advise what to do.
