First, you may need to travle to get the proper evaluation and diagnosis, and if you do not have the right kind of profesionals in your area to provide treatment, then you may have to travel for that as well. Even if you think you know what his dignosis is, you need a professional to help you, and you need to know that you have not missed something important. Most of us are not equiped to do that ourselves.
You can go several ways. A Developmental Pediatrican will do a complete evaluation that will include educational, psychological, nuerological, speech and language, OT, ENT, audiology, genticists, PT, or any other aspect of evaluation that your son needs. A nueropsycholgical evaluation and treatment with a board certified child psychiatrist would be another way to go, but you will need to suppliment speech and langauge, OT, or any other needs, and you may be put in the position to guess if he needs these things or not, and will be responsible for putting the whole picture together yourself. One thing is for certain, you need a very indepth evaluation that will take many professionals many days and hours of evaluation time to get a good handle on what is going on here.
Executive dysfunction is a big part of many nuerodevelopmental issues, and is one processing measure that will be fully exposed in a full evaluation. This is the function of the prefrontal cortex (the part of the brain that is in his forehead) and many conditions have significant executive dysfunction as one diagnostic critera. It is usually not a stand alone diagnosis, and he probalby has a more specific diagnosis (it is kind of like saying that my child has fluid in his lungs, when the diagnosis is asthma and fluid was caused by inflamation and and secondary infection-the fluid is the presentation needing treatment but the problem that needs more indepth treatment is broader.)
A counselor is not the appropriate first line or diagnostic professional. First, get a full scale evaluation with a comprehensive treatment plan, then, seek out the treatment that is recomended in your area if possible, and travel if you can't. He may qualify for school based services too, but you should own the evaluation that holds his diagnosis and should never know less about your son's needs than any state agency. Get as much as you can from the school, then provide the rest with private services. Where is he in the school process? If the executive dysfunction is bad, he cannot be doing well in school, but he must have a broader diagnostic category to recieve services, unless the school decided to serve him as LD. What does the school say?
www.wrightslaw.com will be helpful on the school front, but since you did not mention school, I don't know what to tell you about that just yet.
