He's now undergoing developmental changes related to adolescence, and it could be that you are witnessing the symptoms of an emerging mood disorder (alongside his ADHD). Ask the clinician about this possibility. The chances of such an occurrence increase if there is a family history of mood disorder.
How do you treat Mood disorder?
We found through elimination diets that our son's explosive/angry behavior was caused by corn products. Removing corn from his diet has given us our son back. We also questioned bipolar disorder and depression. There is some evidence of bipolar symptoms in my husband's family. I believe now these symptoms are/were probably undiagnosed food intolerances.
It is a lot of work to change your diet. We basically eat only whole foods. It beats dosing out the paxil everyday - trust me!
My question is this: Is anyone else suffering from Short Term Memory Loss and Brain Fog? I asked his family doctor if there was a test for him such as PET he answered yes but insurance won't cover it and if they did find something there is nothing anyone can do for him. HOGWASH..there has to be some help somewhere. Ps. No abnormal behavioral problems. Sweet boy who respects his peers and elders.
