Too Many Medicines?

My son is 13 and has Aspergers. The doctor has him on FOUR different medicines and I personally think this is just way too much for him and haven't seen any positive results. He's on; Dextrosmphetamine 10mg, Vyvanse 70mg, and Zoloft 50mg in the AM and then Abilify 5mg at night. He is a very quiet child and I worry with taking all these meds he's anger issues will get worse. The doctor says he has both long term and short term memory loss and anxiety. I don't believe either. He can recall things both old and new just fine. I know there is no cure for Aspergers but I firmly believe that he needs occupational therapy because he is severly lacking in social skills and has no friends. Please advise.
Thank you

It clearly sounds like you are displeased with the decision making of the prescribing psychiatrist.  I absolutely recommend seeking a second opinion.  These medications are serious and you need to have a good working relationship with the doctor prescribing them.  A plan should be developed that you understand and agree to including an indication of what behavior, in particular, the medication is targeting, how the effects of the medication will be measured, how side effects will be measured, how decisions will be made about increasing or decreasing the medication, and what would indicate that the medication is ineffective and then how and when would the medication be discontinued.  If you aren’t satisfied with a particular prescriber, definitely seek another.
