<s>[INST] Hi, my son is 20 and he has symptoms that resemble Asbergers Syndrome. He is a 2nd year college student, very bright but difficulty with social skills. How can he be tested for Asbergers? What kind of doctor would request tests, a Psychiatrist? And how do we know that the doctor has the full credentials to make such a diagnois? [/INST] Hi there ~I understand your concerns.  If you know that your son has Asperger's syndrome and need a formal diagnosis from a psychiatrist for benefits, you might do well by visiting with and consulting a psychiatrist who can give your son the diagnosis.  You may have to check with the doctor if the doctor has full credentials to make a diagnosis and contact the state medical board to make that determination as records are available for the doctor's history with the board in your state.I hope this helps.  Take care and have a lovely day! </s>
