I am new to this forum and have questions about ADD/ADHD concerning myself. How do you know that you have ADD/ADHD? Are there tests to take to find out if you have ADD/ADHD? I do not think I had problems when I was a kid but I do think I have problems now is that possible? Can ADD/ADHD develope later in life? What type of professional person does one see to determine if you do have ADD/ADHD? If it is not ADD/ADHD does the same Dr. determine what you may have?
