Has anyone gone through a full-spectrum analysis done by a neuropsychologist to further pinpoint their ADD type?

A coach that my husband and I just met with recommended that my husband get one done. Apparently, it encompasses an IQ test but also uncovers the person's strengths and weaknesses when it comes to visual/auditory/tactile processing and learning styles. They also do some kind of a brain scan via MRI or something like that.

She also talked about there being 5 different "types" of ADD, as well as individual differences between each person. I don't recall the list exactly, but I googled it and found these six types here, on a site called newideas.net:

1. Classic ADD - Inattentive, distractible, disorganized. Perhaps hyperactive, restless and impulsive.
2. Inattentive ADD - Inattentive, and disorganized.
3. Over-focused ADD - Trouble shifting attention, frequently stuck in loops of negative thoughts, obsessive, excessive worry, inflexible, oppositional and argumentative.
4. Temporal Lobe ADD - Inattentive and irritable, aggressive, dark thoughts, mood instability, very impulsive. May break rules, fight, be defiant, and very disobedient. Poor handwriting and trouble learning are common.
5. Limbic System ADD - Inattentive, chronic low-grade depression, negative, low energy, feelings of hopelessness and worthlessness.
6. Ring of Fire ADD - Inattentive, extremely distractible, angry, irritable, overly sensitive to the environment, hyperverbal, extremely oppositional, possible cyclic moodiness.

Would love to hear about your experiences, as it is a very expensive test (something like $600-800) and we're hoping (but not sure) that it is worth the money.
