Hi, I have 3 children, (girls) my 17 year old, has ADHD, and my 13 year old also. My oldest daughter who is 20 years old, has been very close with her sisters, she doesn't have the symptoms for ADHD. My oldest daughter and her father, (my ex-husband), at their house, has "not" seen any signs of ADHD in my two youngest daughters. My 17 year old, was on "Ritilin" 10mg., when she was 13-14, this made her very sleepy, so her doctor took her off of it, and didn't prescribe her with anything else, and she hasn't been back to her doctor since, for ADHD. My ex-husband claimed that she doesn't have ADHD, now her symptoms are worse then ever. My 13 year old has not been on any medication, but right now, her school is seeing serious signs of ADD. I as their mother, have serious symptoms of adult ADHD, and I'm on "Adderall XR" 20mg., and I also feel I need a higher dose per day. My question to you is, "Does anyone in your family have any signs of ADHD" ? The reason I ask is, that if you have ADHD, you can "see the signs in others", and be able to tell if this child is ADHD. Also he may need to stop taking the "Prozac", because I was on prozac, and I had to stop taking with Adderall XR. If you even know someone who is ADHD, and is on medication, let this person come into contact with your husband's son, then they will be able to see signs, if any at all. There is a "Assessment Test" online for ADHD, go to " Web MD", and ask him these questions, and they rate your answers, and give you a score, to let you know the level he is, and just how serious it is, or if he even has ADHD at all. You can copy this test, and the score, and show to his doctor. This may help !!
