Meltdowns and meds

My son has been diagnosed with Aspergers syndrome, ADHD and ODD. He’s a great kid! But he gets angry for no reason sometimes and we have tried several different meds and so far nothing is really working. For some reason he seems to pinpoint all his anger toward my husband which is weird. Currently he is taking Vyannse for the ADHD and then he is also taking Lamical 200mg per day. He is 12 years old. His neurologist wants us to take him to a Child Psycologist (sp?) and we are going to do that. But does anyone have any other suggestions or advice? thanks!! Neva
